$125 - $200 - Masonry, Cinder Block and Stone Chimneys (This is the category that the majority of systems fall under and are required if there are any proposed changes to be made or if there is a purchase/sale of the property involved.)
Level 2 Inspections – Level 2 inspections are required when any changes are made to the system. Changes can include: a change in the fuel type, changes to the shape of, or material in, the flue (i.e. relining), or replacement or addition of an appliance of a dissimilar type, input rating or efficiency. Level 2 inspection is required upon the sale or transfer of a property or after an operation malfunction or external event that was likely to cause damage to the chimney. Building fires, chimney fires, seismic events, as well as, weather events are all indicators that this level of inspection is warranted.
Level 2 inspections are more in-depth than a Level 1 inspection. When a Level 1 or Level 2 inspection suggests a hidden hazard and the evaluation cannot be performed without special tools to access concealed areas of the chimney or flue, a Level 3 inspection is recommended. Level 2 inspections include everything in Level 1 inspections, plus the accessible portions of the chimney exterior and interior including attics, crawl spaces and basements. It will address proper clearances from combustibles in accessible locations.
There are no specialty tools (i.e. demolition equipment) required to open doors, panels or coverings in performing a Level 2 inspection. A Level 2 inspection shall also include a visual inspection by video scanning or other means in order to examine the internal surfaces and joints of all flue liners incorporated within the chimney. No removal or destruction of permanently attached portions of the chimney or building structure or finish shall be required by a Level 2 inspection.
Level 3 Inspections - A Level 3 inspection addresses the proper construction and the condition of concealed portions of the chimney structure and the flue. Removal or destruction, as necessary, of permanently attached portions of the chimney or building structure will be required for the completion of a Level 3 inspection.
Level 3 inspections include all the areas and items checked in a Level 1 and a Level 2 inspection, as well as the removal of certain components of the building or chimney where necessary. Removal of components (i.e., chimney crown, interior chimney walls) shall be required only when necessary to gain access to the area that are the subject of the inspection. When serious hazards are suspected, a Level 3 inspection may well be required to determine the condition of the chimney system.
