According to the National Fire Protection Association (NFPA), defective smoke chambers are the third leading cause of chimney-related house fires. For the safety and efficiency of your fireplace, it is important that any gaps, cracks, or holes in the smoke chamber be sealed and to make the brick corbelling smooth. Because the smoke chamber is a “High Heat” area, any gaps, cracks, or holes can allow excessive heat to attack any surrounding wood or combustibles. The jagged corbelling slows the draft and will provide more surface area for highly combustible creosote and soot to form. Feel free to give Dirty Chimney a call to schedule your yearly Inspection.
National Fire Protection Association (NFPA) 211…The standard for Chimneys, Fireplaces, Vents, and Solid Fuel Burning Appliances 2019 Edition 11.2.1.13…”The inner surfaces of the smoke chamber shall be parge coated smooth, with an insulating refractory mortar…”
2018 International Residential Code – Fireplaces And Chimneys R1001.8…”Smoke chamber walls shall be constructed of solid masonry units, hollow masonry units grouted solid, stone, or concrete… The inside surface shall be parged smooth with refractory mortar conforming to ASTM C199″
Certain homes have water heater tanks that vent into a masonry chimney flue, through a wall, or up through the roof to release the toxic gas carbon monoxide (CO) – the poisonous, colorless, odorless, and tasteless gas. It’s important to have the flue inspected & cleaned if necessary. The flue gases can deteriorate the clay flue liner and cause it to break the tile. Dangerous carbon monoxide gas can be forced into your home through open mortar joints, broken flue liners, and flues blocked by debris.
Cleaning dryer exhaust ducts has become an important service that many homeowners do not yet recognize as necessary. Homes that have a clothes dryer and exhaust on an exterior wall are easily maintained. However; there are many others, especially in new construction, that are improperly installed and represent a real risk of fire. The duct may be vertical or horizontal, it may go under the house or into the attic, or be hidden in the wall or ceiling. It is important to understand how they should be installed. Because the duct is usually 4″ in diameter, the slightest deposit can reduce the ability to exhaust properly. The problem is not usually the dryer, but rather the exhaust system. Removing lint deposits will normally correct the problem. It is required that dryer ducts and transition ducts be inspected & cleaned annually by NFPA 211.

A dirty, damaged, or blocked chimney can lead to a chimney fire or carbon monoxide poisoning. That’s why Dirty Chimney, LLC, and the National Fire Protection Association recommend that homeowners have chimneys checked annually.
“Chimneys, fireplaces, and vents shall be inspected at least once a year for soundness, freedom from deposits, and correct clearances. Cleaning, maintenance, and repairs shall be done if necessary.”
This is a national safety standard, and it takes into account the fact that – even if you don’t use your chimney much – animals may build nests in the flue or there may be other types of deterioration that could make the chimney unsafe.
Factory-built fireplaces should be swept when any appreciable buildup occurs. The logic here is that the deposits are quite acidic and can shorten the life of the fireplace by corroding the different components of the prefab system.
