5 Common Chimney Myths and Misconceptions

Wednesday 19th April 2017

Most people know that keeping their chimney clean is essential to the safe and efficient operation of their fireplace. But there are many myths and misconceptions about chimneys and how to keep them in proper, working order. In this month’s Admiralty Chimney blog, we’ll discuss 5 common chimney myths and misconceptions. Some may surprise you.

1. I don’t use my chimney that often so I don’t need to have it cleaned or inspected. Although creosote buildup may not be an issue, you might be surprised about the amount of debris that can fall into your chimney, or how quickly your structure erodes over time. While cleaning your chimney, your chimney sweep will remove any debris and check for dangerous cracks  the chimney and flue. 

Spring is a great time to schedule a chimney cleaning. Hold off until fall and you’ll have to wait in line for an appointment with everyone else.

2. I have a metal chimney liner so I no longer need annual inspections. While metal liners help protect the interior of your chimney, they are still subject to soot and creosote build-up. Regardless of your liner type and condition, an annual inspection is still recommended by the Chimney Safety Institute of America (CSIA).


3. Cleaning a chimney is easy and something I can do myself. Some household maintenance jobs are best left to the professionals, and chimney sweeping happens to be one of these. For the non-professional, cleaning a chimney can be extremely messy, time-consuming, and dangerous. You need the appropriate equipment, including a respirator (to protect your lungs from soot and creosote). Make it easy on yourself and schedule your chimney cleaning with the CSIA-certified professionals at Admiralty Chimney.

4. Masonry chimneys are indestructible. Unfortunately this is not true. While doing chimney cleanings and inspections, the Admiralty Chimney team frequently finds cracks in masonry chimneys caused by the freezing and thawing of water.

5. Burning pine and other softwoods (which contain large amounts of sap) can cause creosote damage to your chimney. A University of Georgia study put an end to this long-held belief. Creosote forms from burning low-temperature fires, not sap-rich wood. If the wood you burn has dried for at least a year, creosote shouldn’t be a concern.

Don’t be misled by these common chimney myths and misconceptions. Even if you only use your fireplace just a few times a year, it’s important to have your chimney inspected and cleaned annually. Contact the CSIA-certified professionals at Admiralty Chimney today to schedule your annual chimney inspection and cleaning.

Benefits of Cleaning and Inspecting Your Chimney in the Spring

Friday 10th March 2017

Ahhh…springtime. There’s no better season to get your home in order. When you start your spring cleaning, don’t forget about your chimney—it’s been working hard for you these past several months! Here are four reasons why spring may be the best time for cleaning and inspecting your chimney:

Avoiding the Fall Rush

By scheduling your annual chimney cleaning and inspection during the spring, you avoid the fall rush. Most people don’t think about their chimneys until the temperatures start to drop. By scheduling your cleaning now, you won’t have to wait for an appointment.  

Eliminating Foul Odors

The creosote and ash that’s been building up in your chimney can cause unpleasant odors. By having your chimney cleaned after the long winter season, you’ll keep your home smelling fresh.

Prolonging the Life of Your Chimney

When acidic creosote buildup is combined with the moisture from the rain of spring and summer, it can cause deterioration of your chimney’s interior. By removing creosote buildup after the burning season, you can significantly prolong the life of your chimney.

Finishing Repairs Before the Burning Season

To protect the safety of your home and family, the Chimney and Safety Institute of America recommends annual inspections and cleanings by a CSIA-certified chimney sweep. By having your chimney cleaned and inspected in the spring, you’ll have time to take care of any needed repairs before the start of the burning season. Doing so will allow you and your family to safely enjoy the warmth and comfort your chimney all season long.

Hiring the Right Chimney Sweep

Monday 27th February 2017

As our New England winter days are growing longer and warmer, we’re reminded that spring is just around the corner. And with the dawn of this season of renewal comes spring cleaning! As you clean and maintain your home in preparation for the warmer months, don’t forget about your chimney–it’s been working hard for you all winter long. Before you schedule your chimney cleaning and inspection, follow these guidelines for hiring the right chimney sweep:

Ensure Your Chimney Sweep is CSIA-Certified

The Chimney Safety Institute of America (CSIA) is a non-profit organization with a mission of educating and protecting homeowners, and a dedication to providing continuing education for chimney sweep professionals. CSIA-certified chimney sweeps pass two exams and renew their certification every three years. Roughly 1,800 chimney sweep professionals are certified nationwide.

Ask These Important Questions

In addition to confirming that your chimney sweep is CSIA-certified, be sure to ask the following questions:

1. How long have they been in business?  When it comes to the safety and maintenance of your home, experience matters.

2. Do they offer current references? Talk to other customers about their quality of work and level of professionalism.

3. Does the company have unresolved complaints filed against them? An unresolved complaint is, of course, a red flag.

4. Does the company carry valid business liability insurance? Never allow anyone to work on your home without proof of insurance.

5. Does the company ensure that a CSIA-Certified Chimney Sweep will be on the job site? All chimney inspections should be signed off by a CSIA-certified chimney sweep.

Unfortunately, many chimney sweeps lack the education and experience required to protect the safety of your home and family. Following the above guidelines will help you in hiring the right chimney sweep for your home.

CSIA-Certified Chimney Sweeps in Southern NH and Northern MA

At Admiralty Chimney, we take your home and your safety very seriously. We aren’t just licensed chimney service professionals, we are certified by and committed to the standards and ethics of the Chimney Service Institute of America (CSIA).

Preventing Chimney Fires

Friday 27th January 2017

Baby it’s cold outside. During the winter, nothing beats a cozy fire when it comes to bringing warmth and comfort to your home. However, prolonged use of your chimney can lead to creosote buildup, and an increased risk of chimney fires. Preventing chimney fires is easy, though. With a little care and attention, you can safely enjoy the warmth your chimney provides all season long.

Creosote and Chimneys

When wood burns, creosote builds up in your chimney. Depending on the temperature of the fire and how quickly the air is moving away from the fire, this buildup can look black, brown, gummy, hard, shiny, or even flaky. Certain conditions—improper ventilation, burning of unseasoned wood, or drastic changes in burning temperature—accelerate creosote buildup. Creosote is highly flammable and combustible and if too much builds up in your chimney, a fire can start at any moment. To prevent a chimney fire, the Chimney Safety Institute of America (CSIA) recommends “any solid fuel venting” system be annually inspected and cleaned with repairs done whenever needed.

How Well do You Know Your Chimney?

Did you know that most small chimney fires often go undetected? If you’ve had a small fire, you are at risk of significant chimney damage and danger to your home and family. Preventing chimney fires requires that you pay attention to the functionality of your chimney: Is enough air coming through? Are your fires struggling to stay lit due to lack of air? Is there a hot, burning smell even when the fire isn’t lit? Is there a lot of dense smoke? Will your damper not close? (Indicating the safety of the damper has been compromised by fire that’s gotten too hot.) If you’ve answered yes to any of these questions, you may have already had a chimney fire.

Warning Signs of a Chimney Fire

According to the Chimney Safety Institute of America, there are 9 signs that a chimney fire has occurred in your home:

•  “Puffy” or “honey combed” creosote

•  Warped metal of the damper, smoke chamber connector pipe, or factory-built chimney

•  Cracked or collapsed flue tiles, or tiles with large chunks missing

•  Discolored and/or distorted rain cap

•  Heat-damaged TV antenna attached to the chimney

•  Creosote flakes and pieces found on the roof or ground

•  Roofing material damaged from hot creosote

•  Cracks in exterior masonry

•  Evidence of smoke escaping through mortar joints of masonry or tile liners

If you detect any of these signs, contact a chimney service and repair professional immediately!

The Importance of Creosote Removal in NH Chimneys

Friday 4th November 2016

As the temperature starts dropping, we rely more and more on the warmth and comfort we get from our fireplaces. Many people look forward to these times by the fireplace, helping to keep the cost of gas/oil/electric down and our spirits up. But before you settle in for the long months ahead, it’s important that you take the steps necessary to make sure your chimney is safe and clear of any dangers that could cause you trouble. So that when you do settle in front of your warm fire, you will know all is safe.

How Does Creosote Develop?


Every time you light a fire in a wood burning stove or fireplace, the condensation that occurs when the smoke is traveling up the chimney creates a substance called creosote. Creosote is highly combustible, and can be dangerous for you and your chimney.

Depending on the temperature of the fire and how quickly the air is moving away from the fire, creosote can look black, brown, gummy, hard, shiny, or even flaky. However it appears, if too much creosote accumulates in your chimney, a fire can start at any moment whenever the temperature gets hot enough.

What Can I do About Creosote?

Factors that cause creosote to form in your chimney lining faster are: restricted air, burning unseasoned wood, cooler chimney temperatures, and slow moving smoke. All of these factors can create the situation that would allow the creosote to ignite within the chimney.

Depending on how quickly the creosote builds up, you may need more frequent cleanings than you originally planned on. There are ways to avoid creosote developing in your chimney quickly, but you’ll never be able to completely stop it from forming.


Getting Service from the NH Chimney Experts

The most effective way to deal with creosote is to get a trained professional to inspect and care for your chimney. Each home and chimney system is different. Having someone with the knowledge and training to help your chimney stay safe and clean is critical for the safety of your home and family. 

Admiralty Chimney is a full-service chimney company, certified by the Chimney Safety Institute of America. Contact Admiralty Chimney today and schedule your inspection and chimney cleaning, so you can relax and have peace of mind knowing your chimney is safe and operational.

Protecting Your Chimney From Water Damage in NH

Tuesday 18th October 2016

Believe it or not, your chimney is not as likely to become damaged from heat, smoke, and corrosion as it is from excess moisture. Water can damage your chimney in a variety of ways, which is one reason that it pays to have a regular chimney inspection!

Moisture and Chimney Masonry

Moisture is always in the air, but it poses a greater threat during prolonged times of humidity or heavy fog. Water seeps into the cracks between brick and mortar over time, softening and eroding these materials. If preventative measures are not in place, your chimney could lose its integrity and develop a tilt, making it unsafe for regular use.


In order to maintain a functional, robust bond between stone, brick, and mortar, moisture must be kept at a minimum. Water can also get inside your chimney and cause rusting on metal fixtures like dampers and hinges. With the added damages of moisture freezing, expanding, and thawing, New Hampshire chimneys have the odds stacked against them!

Protecting Your Chimney From Moisture

There are a few options when it comes to protecting your chimney from water damage.

  • Chimney caps. Having a rust-proof, all weather covering over your chimney keeps out a significant amount of rainwater and prevents internal moisture damage. Yet another outstanding reason to install a chimney cap!
  • Flashing. These sections of sheet metal that surround your chimney’s base are excellent for preventing moisture damage. Flashing should be inspected, sealed, and maintained regularly so it remains effective.
  • Sealants. There are plenty of great brick and masonry water repellents out there, known as penetrating sealers. We prefer the spray-on sealer called ChimneySaver.

Your NH Chimney Specialists

It’s no secret that chimney maintenance protects the value of your home. As your New Hampshire chimney specialists, we want to help our fellow homeowners maintain safe and effective chimneys before the coming winter months. Contact Admiralty Chimney today to schedule your inspection, cleaning, or waterproofing appointment!

Fall Fireplace Safety in Southern NH

Monday 12th September 2016

The fall is a great time of year to start thinking about your chimney and fireplace again. We always recommend a chimney inspection or a cleaning to start your winter season off right. As you get your chimney ready for the colder months, fireplace safety is something you should also be thinking about.

Tips for preparing & using your fireplace

When the temperature dips over the next few months, you’ll want your fireplace to keep you warm, but you’ll also want it to be a safe and reliable fixture in your home. Never underestimate the value of safety when it comes to fires. It always pays to be prepared and informed!

Install a firebox screen. Having a screen around your open fireplace will ensure that everyone remains a safe distance from the flames, and that no embers will make it beyond the hearth

Build proper fires. Don’t use too much loose paper when you start a fire. Instead, keep wood shavings and splinters on hand. They’ll light quickly and won’t create burning ash.

Burn the right wood. Softwoods like pine and cedar don’t burn cleanly. They put out resin in their smoke, which forms creosote inside your chimney. It’s best to stick with cleaner burning hardwoods like oak or maple.


Practice fireplace safety in your home

When it comes to fireplace safety, everyone in your home should be involved in preventing an accident or a potential tragedy. Make sure your family knows how to operate the fireplace mechanisms such as the flue and damper. Be sure to establish fire safety plans, including escape routes for different areas of your home.

Always remember, common sense is the best way to prevent a fire. Other than the obvious things like keeping kerosene away from open flames, make sure you keep an eye on burning candles. Also, check your chimney periodically to ensure there’s a proper smoke flow, and test your smoke alarms and carbon monoxide monitors regularly.

Don’t hesitate to contact Admiralty Chimney. Be sure to schedule your inspection or cleaning appointment before winter is upon us.

Types of Chimney Dampers to Install in NH

Friday 12th August 2016

As a homeowner, you probably have a decent idea of how your chimney works. If not, here’s a quick run-down:

Fuel is burned in the firebox, and the exhaust and smoke travel through the flue pipe. The flue pipe enters into the chimney body, and is fixed to the chimney liner. The liner travels up the chimney, and the rest is history.

Between the firebox and the chimney top, there are several key features. One of the most important is the chimney damper.

What is a Chimney Damper?

Dampers are flaps that form a tight seal inside part of the chimney, closing off the interior when the chimney is not in use.

Some dampers are made entirely of steel, and others have a rubberized gasket that allows for a tighter seal. Chimney dampers serve two primary purposes: energy efficiency and pest prevention. Let’s take a look at the two types of chimney dampers.

Top Sealing Chimney Dampers

As the name implies, these dampers are fixed to the very top of your chimney. They come either as individual units (as seen on the left), or housed within specialized chimney caps. After they’re installed, top sealing dampers require very little maintenance. A thin steel cable attaches to the shifting mechanism and runs the length of your chimney, allowing you to open or close the damper from inside your home.

Top sealing dampers are considered to be the most effective for preventing wildlife and insects from entering and nesting in your chimney during the off-season. They compliment chimney caps nicely in this aspect, and provide a secure, airtight seal.

Throat Dampers

Throat dampers are located much closer to the base of your chimney. In gas or pellet stoves, they’re usually fixed just outside the firebox, inside the steel pipe that enters the chimney. In older brick fireplaces, throat dampers are usually not visible, but are operated in a similar way to top sealing dampers.

Because throat dampers are located nearest to the interior of the home, they allow for greater energy efficiency. Rather than allowing your entire chimney to fill with warmth from your home, these dampers create a seal before heat can enter the chimney. When you’re not actively using the fireplace, it’s best to keep throat dampers closed in the winter.

Which Chimney Damper is Best for NH?

In a word, both. The type of chimney damper you use should be based on where you live. In New Hampshire, both wildlife and energy efficiency are top concerns when it comes to chimneys. With a top sealing damper, your chimney is most effectively sealed off from any type of infestation during the off-season. With a throat damper, your home remains warmer for a longer period of time after each use.

Many New Hampshire homeowners choose to install both types of dampers, and we can’t argue with the best of both worlds! If you’d like more information before you decide, or if you’d like to have a damper professionally installed, give us a shout. Our crew at Admiralty Chimney Service is always happy to help!

Benefits of Having a Chimney Cap in NH

Wednesday 20th July 2016

Have you ever taken the time to really look at your chimney? Not too many people do. That’s the thing about chimneys…when they’re working like a charm, they’re all but invisible. And during the summer months? Most folks don’t give them a second thought.

When summer comes to a close though, people begin noticing their chimneys again. They realize the masonry looks a bit crumbled in places. The flue is stiffer than it used to be, and there’s an awful lot of creosote inside the fireplace. And what’s that on top of the chimney? Did that really used to be a cap?


The Importance of Chimney Caps

If a chimney cap is all rusted away, it’s not doing you any good. Here are the main purposes that a chimney cap serves:

  • Keeping animals out. Squirrels, mice, insects, and swifts will make nests in unused chimneys
  • Keeping rain out. Caps direct rainwater away from your chimney, preventing the masonry from becoming waterlogged and damaged.
  • Keeping flaming debris in. If bits of burning materials escape your chimney and land on your roof, they can cause house fires.
  • Improving air flow. Caps block the wind enough to prevent downdraft, meaning smoke flows freely away from your house and not back down the chimney.

Chimney caps are important for the structural health of your chimney, for preventing moisture damage, and preventing roof fires. They serve so many important safety functions, we believe it’s important for every homeowner to have a chimney cap.


Chimney Cap Installers in NH

At Admiralty Chimney, we have a saying. You can’t go wrong with a chimney cap. Catchy, right? It’s just plain true. They protect your chimney and your home in so many different ways, and summer is the perfect time of year to install them.

There are several types of caps, and once our experts take a look at your chimney, we’ll know exactly which one is perfect for your needs. The collage above will give you an idea of what chimney caps can look like. Depending on your local climate, type of chimney, and budget, certain caps will be better than others.

Don’t worry, you really don’t have to think much about your chimney this summer. Just give us a quick call at 603-594-0400 to have a cap installed. If you already have one, great! Saftey’s the word, and having a chimney cap is a big step in the right direction.

Chimney Issues in Old NH Houses

Wednesday 15th June 2016

One of the great aspects of living in New Hampshire is the abundance of old Colonial houses. They stand tall and resolute as testaments to the living history of New England, stretching back for hundreds of years. The problem with houses built over a century ago is that, well, they were built over a century ago.

Before 1900, there were hardly any building regulations, and certainly none to compare with the extensive chimney safety codes of today. When it comes to chimneys and fireplace apparatus, old houses are usually lacking in the safety department. Let’s take a look at some specific chimney issues that are often present in old or unused houses.

  • Infestation. Swifts, squirrels, and rodents love making nests inside chimneys because they offer safety from predators and great shelter. If the chimney wasn’t properly blocked off for storage, there are probably nests inside the flue.
  • Masonry. Leaning chimneys are a result of age, gravity, and crumbling mortar. In old houses, interior and exterior mortar must be addressed before usage.
  • Lining. Chimney liners become caked with creosote over time, but that’s a small issue when compared with the fact that before 1900, most chimneys were built entirely without liners! Hence, increased home fires.
  • Cleanout Doors. Another required safety feature of modern wood burning fireplaces, chimney cleanout doors are not common in old houses. One less safety feature, check.
  • Flashing. This is the material overlapping the chimney base and the roofing. Today, flashing is made from sheet metal. Back in the day, flashing was just lots of mortar.

Take a look at this image to get an idea of the inner workings of an old, multi-story Colonial chimney. Then keep in mind that the codes of today, such as height and depth dimensions and other safety features, were not common practice in chimney building.

Chimney Restoration for Old NH Homes

Do you live in a beautiful old Colonial house? Maybe you’ve been eyeing that walled-off fireplace for some time, but you always thought it would be impossible to bring it into working condition.

Preparing Your Chimney for the Off-season in NH

Tuesday 3rd May 2016

Now that the weather is finally warming up, you can start thinking about stowing your chimney for the off-season. At Admiralty Chimney, we recommend that you have your chimney inspected and cleaned as part of your off-season chimney storage.

Preparing your chimney for storage

Close the damper. If you have a wood burning fireplace, the damper should be closed throughout the summer months. If you have a gas stove, it’s best to leave the damper open slightly during the off-season to prevent the buildup of toxic gasses in your home.

Install a chimney cap. Chimney caps are great all year round, as they improve the safety of your home and chimney. They prevent pests from entering the chimney, and they help to

contain sparks and flaming debris during usage.

Clean the hearth. The ashes and soot in your fireplace create

airborne particles that can be dangerous to inhale. Cleaning your fireplace early in the off-season eliminates this issue.

If you haven’t had your annual chimney inspection yet, don’t delay! Give us a call at 603-594-0400 or contact us online today to schedule your inspection or cleaning. We look forward to hearing from you!

NH Spring Chimney Cleaning & Inspections

Tuesday 12th April 2016

Now is the time to take action. Schedule your chimney cleaning and inspection in the Spring. Now is the perfect time to get your chimney cleaned and inspected to be ready for the next winter season.

3 Benefits of spring chimney cleaning

  1. Peace of Mind:  Knowing your chimney will be safe and ready for the next winter season.
  2. Identify issues early. Your chimney might have damage from heavy usage.

By fall, winter is just around the corner and your chimney should ready with no surprises.
  3. Reduce odors. Did you know that as the weather gets warmer, creosote and other chemical reactions that have built up in your chimney over the winter can begin to emit a foul odor? A professional cleaning will clear that right up, leaving your chimney odor free and ready for next season’s use.

Admiralty Chimney Service, along with the National Fire Protection Association, recommends having a thorough chimney inspection and cleaning every year. Most of us homeowners have spring cleaning rituals, a time when the weather allows us to get to those “hard to reach” places. Why not check your chimney off the list this spring, too?

NH Chimney Masonry and Mortar Repairs

Tuesday 8th March 2016

March is the time of year when we begin restoring chimneys. Although this winter has been tamer than some, the temperature around New Hampshire has constantly fluctuated above and below freezing. Because of this, chimney mortar and masonry has experienced constant freezing, thawing and refreezing.

NH Winter Chimney Damage

Mortar holds up most efficiently when the weather is consistently above 40 degrees. During the winter, the moisture trapped inside chimney mortar freezes and expands, creating tiny cracks and fractures. While this damage isn’t severe enough to ruin a chimney’s masonry in one season, over time it causes serious structural damage.

Each winter, chimney mortar erodes a little more. With the inconsistent temperatures of this past winter, chimney mortar has certainly experienced this effect. When it comes to masonry issues, it’s important to act before your chimney becomes dangerously unsound.

Chimney mortar inspections & repairs in NH

During your annual chimney inspection, the experts at Admiralty Chimney Service will thoroughly examine and assess the condition of your chimney’s mortar and masonry.

We can point out to you areas of your chimney that are experiencing cracking damage. If masonry repairs are required, we will do the job thoroughly and efficiently. Fresh masonry repairs performed in early spring are ideal, as the weather allows for mortar to harden properly, without freezing.

After every masonry project, we spray the surface of your chimney with ChimneySaver, a sealant and water repellent for masonry. This final touch increases the lifespan of your chimney by preventing water absorption and offering freeze/thaw protection.

Got questions? Call Admiralty Chimney Service at 603-594-0400 for more information or a free service estimate. You can also contact us online to schedule your appointment.

Does your chimney need emergency repairs?

A damaged chimney is dangerous for many reasons, and any problems that arise during the winter should be dealt with quickly. Some of the issues may include:

  • Flu damage leading to smoke in the house
  • Hearth and fireplace damage from dried, crumbling masonry
  • Chimney liners clogged with creosote buildup
  • External masonry damage or chimney cap damage

Chimney care is all about maintenance.

Our experts will identify issues early on through chimney inspections. You shouldn’t wait until your chimney falls apart, or worse, before calling your local chimney company. Admiralty Chimney is here to keep your chimney safe and efficient, all winter long.

Burn, Baby, Burn: Safe Fire Practices

Thursday 17th December 2015

During the wintertime, everyone wants to just curl up by the fire on a cold December day. It’s important, however, to learn the proper uses and potential safety hazards before starting up that fire. Here are some burning practices for creating that perfect cozy winter atmosphere, while keeping both your fireplace and your home safe.

What should I burn in my fireplace?

It’s best to burn wood that has been stored outdoors and kept off the ground. The wood should also be shielded by a tarp or other protective covering.

Use newspaper, dry kindling, or an all-natural fire starter. You can also install a natural gas or propane log lighter in your open fireplace.

Most wax and sawdust logs are made for open hearth fireplaces only. Check the instructions for your wood stove or fireplace before using artificial logs. If you are using manufactured logs, be sure that they are made of one-hundred percent compressed sawdust.

What should I avoid burning in my fireplace?

  • Do not burn wet, rotten, or moldy wood.

Fire Safety Tips and Home Escape Routes

Wednesday 4th November 2015

Fire can spread quickly throughout your home, leaving your family as little as one or two minutes to escape after the smoke alarm goes off.

With limited time during a high-pressure situation, it is important for your family to plan ahead by coming up with a fire escape route for your home. Here are some basic fire escape planning tips in case of an emergency.

1.) Inspect all exits in your home.

Draw a map of your house and plan out the different ways your family will be able to exit safely. Review this map with your children so that they will know how and where to exit in case of a house fire.

2.) Choose a meeting place.

Find an outside location where you can all meet that is a safe distance away from the house. Mark this location on your escape map so that you will all know where to meet.

3.) Test your smoke alarms.

Double check that all of your smoke alarms are equipped with working batteries. It’s important that your children can easily wake up to the sound of the smoke alarm going off.

4.) Practice makes perfect.

Practice your escape route with your family so that they will know how to respond if there is a real house fire. Planning ahead will prevent you or your family members from being unprepared during a dangerous situation.

5.) Do not reenter the building.

In the case of a real house fire, do not go back into the burning building under any circumstance! If someone is missing, let your fire dispatcher know when you make the call. For your safety, allow firefighters with the proper equipment and training to enter the house during an emergency.

4 Reasons to Install a Chimney Cap on Your Home

Monday 12th October 2015

Chimneys add to the beauty of a home, but they also protect your family from harmful smoke and gases that would otherwise remain in your house. Many homeowners take steps to protect themselves by having a chimney installed in their home, but chimneys also need to be protected in order to remain functional and safe.

One way of protecting your chimney is by installing a chimney cap. A chimney cap is a stainless steel device fitted to the top of a chimney to improve the airflow. We recommend that homeowners have them installed because of their many benefits.

So what are some of the benefits of installing a chimney cap?

1.) Chimney caps prevent moisture from damaging the chimney.

A properly installed chimney cap will protect your crown and help to prevent harmful moisture from rain, snow, and ice from getting into the chimney cavity. Moisture entering the chimney can lead to rapid deterioration, expensive repairs, and safety issues. 

Chimney caps are designed to redirect water away from the top of the chimney and over the sides of the chimney.

2.) Chimney caps prevent animals from accessing the chimney cavity

Chimneys make a great place for small animals and birds to nest because of their warmth and safety from predators. This can cause serious problems for both the homeowner and the critter. Once they get in, they can’t get back out. 

Birds, squirrels, raccoons and other animal nests will block the path of smoke and force the smoke to settle back into your home. This can cause soot damage or even carbon monoxide poisoning. Installing a chimney cap with mesh siding will prevent animals from entering your chimney and your home.

3.) Chimney caps keep debris out

Debris such as leaves, twigs, and trash can easily enter a chimney and clog the flues and the pathway of the smoke. This can lead to blockages or even chimney fires. If you have the proper chimney cap installed, leaves and other debris will not get past the wire mesh, keeping your chimney clear and safe. 

4.) Chimney caps protect against fires

Embers and large sparks from fireplaces can travel up and out the chimney flue. A large enough spark could easily exit the chimney, causing a roof fire or the nearby brush or leaves to catch fire. If this happens, it can also cause internal damage to the chimney itself. The wire mesh of a chimney cap keeps these sparks contained until they eventually burn out.

Have Admiralty Chimney install your chimney cap today.

If you want to maximize the lifespan of your chimney and protect your valuable investment, installing a chimney cap is a great place to start. Admiralty Chimney Service recommends and installs stainless steel caps, and all our caps come with lifetime warranties. Give us a call today at 603-594-0400 to learn more!

Chimney Inspections for Safety and Health

Thursday 17th September 2015

As a homeowner, having your chimney inspected every year is one of the smartest moves you can make. There’s no substitute for an expert pair of eyes identifying hazards before they become destructive.

Chimney inspections are important for proper fire safety.

Chimney fires are always unexpected and can be devastating. Even when contained, chimney fires can cause massive structural damage to both mortar and chimney linings.

A regular chimney inspection will identify potential fire hazards such as pest infestation, chimney swift nests, soot and creosote buildup, and damage to your chimney lining before these things cause any serious damage.

Chimney inspections are important for your health.

Creosote is a highly flammable, oily brown material that cakes onto a chimney’s interior lining. Creosote can be either crusty or tar-like, and is a byproduct of the combustion of firewood or pellets. Over time, creosote builds up in chimneys, creating a carbon residue that is both a fire hazard and a health threat. If not inspected and removed regularly, creosote can cause skin and eye irritation as well as respiratory disease.

Chimney soot is also formed from the incomplete combustion of firewood or pellets. Made from small particles of carbon, soot is very dangerous to inhale and can cause a variety of respiratory diseases.

Chimney swifts are small birds that prefer to nest in chimneys, as they offer safety from predators. Chimney swifts, like many birds, have been known to carry a fungus that causes histoplasmosis, a dangerous and potentially deadly flu-like infection. Chimney swift droppings often collect inside chimneys over time, releasing airborne pathogens that can infect you or your family.

Carbon monoxide is another silent killer that can originate from a dirty chimney. Carbon monoxide is a byproduct that is released when wood or fuel does not burn completely. While a carbon monoxide detector can alert you when the gas is present, an annual chimney inspection can identify the flaws in a chimney, preventing the gas from ever being present in your home.

It’s never wise to put off your annual chimney inspection. With the winter months approaching, now is the time to identify and address the hazards lurking in your chimney.
