COMMON QUESTIONS

chimney sweeping FAQS

Can a chimney fire damage a home even if no one notices it?

Yes, slow-burning chimney fires are particularly insidious because they can go undetected while still causing significant damage. These fires occur at lower temperatures than dramatic chimney fires but can crack flue liners, damage mortar joints, and warp metal components. Over time, this hidden damage creates gaps through which heat and flames can reach combustible framing materials, creating a house fire risk even during normal subsequent use.

What are the different stages of creosote?

• First-degree: Flaky, sooty deposits that are relatively easy to brush away
• Second-degree: Harder, tar-like flakes and crusts that require more aggressive cleaning
• Third-degree: Thick, glazed, and rock-hard deposits that are extremely difficult to remove and may require special chemical treatments or professional restoration

First-degree creosote is normal with regular burning and routine sweeping. Third-degree creosote is a serious hazard and significantly more expensive to address.

What should I never burn in my fireplace?

• Wet or green unseasoned wood
• Treated, painted, or stained lumber
• Cardboard, trash, or plastic
• Driftwood (contains salt, which is corrosive)
• Artificial logs not specifically designed for your appliance type

Burning these materials produces harmful chemicals, excessive creosote, and can void your appliance warranty or home insurance coverage in the event of a fire.

How often should I have my chimney swept?

The NFPA recommends that chimneys be inspected at least once a year and swept as needed based on the level of buildup. As a general rule, most wood-burning fireplaces and stoves used regularly should be swept at least once per year, typically before the heating season begins. Heavy users (like those burning several cords of wood per season) may need sweeping more frequently, sometimes two or more times per year.

What does a chimney sweep actually do during a visit? 

• Protect your home by laying drop cloths and sealing the fireplace opening
• Use specialized brushes and rods to loosen and dislodge creosote and soot
• Vacuum debris from the firebox, smoke chamber, and flue
• Inspect accessible components for damage, deterioration, or blockages

Many sweeps also perform a visual inspection as part of the service, though a full Level 2 inspection with camera equipment is a separate and more thorough process.

What is chimney sweeping?

Chimney sweeping is the process of cleaning the interior of a chimney flue to remove creosote buildup, soot, debris, blockages, and other combustion byproducts that accumulate with regular fireplace or stove use. A professional chimney sweep uses specialized brushes, rods, and vacuum equipment to thoroughly clean the flue from the firebox to the chimney cap. Regular sweeping is essential for safe fireplace operation and is recommended by the National Fire Protection Association (NFPA).
