Closing Out the Burning Season: Key Fireplace and Chimney Considerations

While winter tends to linger in New England, we’re definitely approaching the end of the burning season. Now is the time to think about your chimney and fireplace’s maintenance and long-term care. Why? Because what you do after the season can have a big impact on your heating system’s safety, efficiency, and repair costs down the road. Here’s what you should be considering as spring approaches.

1. Schedule a chimney inspection.

With regular use, soot, creosote, and debris build up inside your chimney. After the burning season, scheduling a professional chimney inspection will help:

• Identify creosote buildup (a leading cause of chimney fires).

• Detects cracks or damage in the flue.

• Spot early signs of water intrusion or structural issues.

Spring inspections are ideal because you’ll have more scheduling flexibility and plenty of time to address any issues before next fall.

2. Schedule a chimney cleaning.

Even if you didn’t use your fireplace a lot this season, even small amounts of creosote buildup can become dangerous over time. Cleaning your chimney at the end of the season:

• Removes flammable residue.

• Prevents lingering smoky odors during humid months.

• Ensures your system is ready for next year.

Again, it’s much easier (and often more convenient) to schedule a chimney cleaning now, rather than scrambling in the fall when everyone else is booking appointments.

3. Check for moisture and water damage.

Melting winter snow, spring rain, and increased humidity can wreak havoc on your chimney. Water is one of the most damaging elements for masonry chimneys, leading to cracking, spalling, and deterioration. After the burn season ends, take a moment to look for:

• White staining (efflorescence) on the exterior brick

• Rust on the damper or firebox components

• Musty or damp odors coming from the fireplace

If you notice any of these signs, it’s worth having a professional assess the situation. Preventative waterproofing or minor repairs now can help you avoid costly work in the long run.

4. Inspect the chimney cap and crown.

Caps and crowns protect chimneys from water damage, animal invasions, and debris buildup. Winter weather can be especially harsh on these components, causing cracks or loosening. A quick inspection can help identify:

• Missing or damaged chimney caps

• Cracks in the crown that allow water in

• Blockages from leaves, animal nests, or debris

Addressing these issues in the off-season ensures your chimney stays protected year-round.

5. Close the damper (but keep airflow in mind).

Once you’re done using your fireplace for the season, ensure the damper is properly closed to prevent drafts and improve energy efficiency. Proper damper use can help:

• Reduce energy loss from your home

• Prevent humid air from entering the chimney system

• Keep pests from making their way inside

Note: Before closing your system for the season, ensure any residual moisture has dried out. 

6. Take care of any needed repairs.

A common mistake many homeowners make is waiting until the first cold snap to address any needed chimney concerns or repairs. By then, most chimney professionals are booked weeks out, and any minor issues may have become larger, costlier problems. Spring and summer are the best times to:

• Repair cracked flue liners

• Replace damaged components

• Repoint deteriorating mortar joints

Getting ahead of repairs ensures your fireplace is safe and ready when you need it most.

7. Think ahead to next season.

Take a moment to reflect on how your fireplace performed this winter. Did you notice smoke backing up into the room? Did you experience any unusual odors or have difficulty starting fires?  These are all clues that your system may need attention.

Addressing these issues now means you’ll be able to enjoy your fireplace with confidence in the next burning season.

Troubleshooting Common Chimney Issues

A fireplace is a beloved feature in many New England homes, providing warmth and comfort during the long winter months. But like any complex system, over time, problems can develop that affect its safety and efficiency.

At Admiralty Chimney, we help homeowners identify and resolve fireplace and chimney issues before they become safety hazards or lead to costly repairs. Below are some of the most common problems we see--and what you can do about them.

1. Smoke Coming Into the House

What’s going on?

If smoke enters your home instead of going up the chimney, it’s usually a drafting problem.

Common causes:

• Creosote buildup (narrows the flue)

• Blocked chimney (nests, debris, snow, or ice)

• Cold air trapped in the flue

• Improper chimney height or design

Troubleshooting tips:

• Make sure the damper is fully open before lighting a fire

• Crack a window slightly to improve airflow

• Warm the flue by lighting a rolled newspaper before starting a fire

If smoke problems persist, contact us, and we’ll come take a look at your system.

2. Excessive Creosote Buildup

What’s going on?

Creosote is a black, tar-like substance that forms when wood doesn’t burn completely. In New England’s extended burning season, creosote can accumulate quickly.

Why it matters:

• It’s highly flammable

• It reduces chimney efficiency

• It’s the leading cause of chimney fires

Troubleshooting tips:

• Burn only seasoned, dry firewood

• Avoid smoldering or low-temperature fires

• Schedule annual chimney cleanings

Creosote cannot be safely removed without professional tools, so don’t try to scrape it yourself.

3. Chimney Leaks and Water Damage

What’s going on?

Water is one of the most damaging elements for chimneys, especially with New England’s freeze-thaw cycles.

Common entry points:

• Cracked or missing chimney crown

• Damaged flashing

• Porous or deteriorating masonry

• Missing chimney cap

Troubleshooting tips:

• Look for water stains on ceilings or walls near the chimney

• Check for rusted dampers or firebox components

• Install a chimney cap to keep rain and snow out

Ignoring water damage can lead to major structural repairs.  Contact our team to schedule an inspection and determine the best course of action.

4. Cracked or Deteriorating Masonry

What’s going on?

Your brick-and-mortar chimney expands and contracts with temperature fluctuations.

Why it matters:

Over time, this can cause cracks, loose bricks, or crumbling mortar joints.

Troubleshooting tips:

• Inspect your chimney exterior each spring and fall

• Look for white staining (efflorescence), which signals moisture issues

• Address small cracks early before they worsen

Schedule any needed masonry repairs during the spring and summer months, when temperatures are warm enough for the mortar to cure properly.

5. Fireplace Won’t Stay Lit

What’s going on?

If your fire keeps going out, airflow is usually the culprit.

Possible causes:

• Closed or partially closed damper

• Blocked flue

• Negative air pressure in the home

• Oversized firebox or undersized chimney

Troubleshooting tips:

• Confirm the damper is fully open

• Use dry kindling and proper fire-building techniques

• Avoid running kitchen or bathroom exhaust fans while starting a fire

Persistent issues should be evaluated by a chimney professional. Contact our office to schedule an appointment. 

6. Strange Odors From the Fireplace

What’s going on?

Fireplace odors are common in humid New England summers or after heavy rain.

Typical causes include:

• Creosote mixing with moisture

• Animal nesting materials

• Poor ventilation

Troubleshooting tips:

• Keep the damper closed when the fireplace isn’t in use

• Install a chimney cap

• Schedule a cleaning if odors linger

Can Your Fireplace Get TOO HOT?

When temperatures plummet in New England, there’s nothing like a warm fire to take the chill off. But can your fireplace get too hot? Yes. This is called over-firing, and it can damage your fireplace or even cause a chimney fire. Here are the causes and signs of over-firing, along with how to prevent it.

Causes of over-firing:

1. Too much fuel: You don’t need to fill every square inch of your firebox with wood. Most standard fireplaces accommodate 2 to 3 logs measuring 3 to 6 inches in diameter and 16 to 18 inches in length. Once you have a good fire going, add one log at a time to maintain steady heat. 

   
   

2. Too much oxygen:  While oxygen is essential for a strong, efficient fire, too much air can cause it to burn too quickly, reducing heat output and increasing wear on your fireplace and chimney. 

   NOTE: Air-pumping bellows should only be used with a stagnant fire.

3. Burning the wrong materials: Use only seasoned hardwood (oak, maple, ash, or birch) with a 15-20% moisture content, as it burns more predictably and at a safer temperature.

Signs that your fireplace is too hot:

Recognizing the signs of over-firing can help prevent damage and keep your home and family safe:

• Loud roaring sounds similar to a blowtorch or a freight train

• Flaking, cracked, or broken firebricks

• Strong metallic burning odors

• Glowing red dampers, grates, or doors

• Warping or deformed metal parts

• Sparks or embers shooting up the flue

Preventing over-firing:

• Only burn seasoned hardwood.

• Follow the manufacturer's guidelines regarding airflow settings and the recommended size and amount of wood.

• Install a heat shield or hood to direct heat away from TVs or mantels.

• Use a hearth thermometer to ensure the area surrounding your fireplace remains below 150°F. (For specific temperature recommendations, read the manufacturer’s guidelines.
