chimney sweeping FAQS

What type of wood should I burn in my fireplace?

Hardwoods such as oak, maple, ash, cherry, and hickory are the best choices for fireplace burning because they are dense, burn longer, produce more heat, and generate less creosote than softwoods.

The wood must be properly seasoned (dried for at least 6 to 12 months after cutting) to achieve a moisture content below 20%. Burning wet or freshly cut wood produces excessive smoke, poor heat output, and rapid creosote buildup.

How do I know if I've had a chimney fire?

• A loud cracking, rumbling, or roaring sound from the chimney
• Dense smoke or unusual odors coming from the fireplace
• Visible flames or sparks from the chimney cap
• Puffy, honey-combed, or blistered creosote on flue walls (observed during inspection)
• Warped or damaged damper, firebox walls, or chimney cap

If you suspect a chimney fire has occurred, stop using the fireplace immediately and schedule a Level 2 inspection before burning again.

What is creosote and why is it dangerous?

Creosote is a dark, tarry substance that forms when wood smoke cools and condenses on the interior walls of the chimney flue. It is highly flammable and is the primary cause of chimney fires, which can reach temperatures exceeding 2,000°F and cause serious structural damage to the chimney and surrounding home. The NFPA and chimney safety organizations consider creosote buildup one of the leading fire hazards in residential homes.

What should I do if I have a chimney fire?

If you observe signs of an active chimney fire, your first step is to call 911. Close the glass doors and damper if it is safe to do so, which can help cut off oxygen supply to the fire. Evacuate the home and do not attempt to fight the fire yourself – chimney fires can spread to structural components very quickly, and professional firefighters are equipped to handle them safely.

What is a chimney fire? 

A chimney fire occurs when accumulated creosote deposits inside the flue ignite, creating an intense, rapidly burning fire within the chimney structure itself. Chimney fires can be violent and dramatic – producing loud cracking or rumbling sounds, dense smoke, and flames shooting from the chimney top – or they can be slow-burning and go undetected. Both types are dangerous and can cause serious structural damage and potentially spread to the rest of the home.

How can I tell if my firewood is properly seasoned?

Well-seasoned firewood has several identifiable characteristics. It will feel lighter than freshly cut wood, have visible cracks or checks at the ends of the logs, and produce a hollow "clunk" sound rather than a dull thud when two pieces are knocked together.

A wood moisture meter, available at most hardware stores, is the most accurate way to confirm moisture content – properly seasoned wood should read below 20%.
