COMMON QUESTIONS

chimney sweeping FAQS

What are the different stages of creosote?

Creosote is generally classified into three degrees of buildup:

• 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 causes excessive creosote buildup?

Several factors contribute to faster and heavier creosote accumulation. Burning wet or unseasoned wood is the most common cause, as it produces more smoke and lower combustion temperatures. Other contributing factors include restricted air supply, an oversized flue, burning fires at low smoldering temperatures for extended periods, and poor chimney draft. Addressing these burning habits is just as important as regular sweeping for keeping creosote levels manageable.

What questions should I ask a chimney sweep before hiring them?

Before scheduling service, consider asking:

• Are you certified or a member of industry organizations?
• Are you licensed and insured in this state?
• What does your sweep service include – cleaning only, or also a basic inspection?
• Do you provide a written report of your findings?
• What is your process for protecting my home during the sweep?

A professional, reputable sweep will answer these questions confidently and provide documentation of their credentials.

What maintenance can I do between professional sweepings?

Between annual professional sweepings, there are several things homeowners can do to maintain chimney health:

• Visually inspect the firebox for obvious debris or damage before and after burning season
• Check that the damper opens and closes fully and seals tightly
• Look for signs of water intrusion such as staining, efflorescence, or rust
• Remove any visible debris from around the chimney cap from the ground

These basic checks help you catch developing problems early and give your professional sweep useful information during their annual visit.

Why is chimney sweeping important? 

Chimney sweeping is one of the most important home maintenance tasks for anyone who uses a fireplace, wood stove, or other fuel-burning appliance vented through a chimney. Without regular cleaning, creosote (a highly flammable byproduct of burning wood) accumulates on the flue walls and can ignite, causing a dangerous chimney fire. Sweeping also removes blockages such as bird nests and debris that can cause carbon monoxide to back up into the living space.

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.
