COMMON QUESTIONS

chimney sweeping FAQS

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.

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.

Are creosote-removing products a substitute for chimney sweeping?

No – creosote-removing chemical products and “sweeping logs” can help loosen and reduce light deposits between professional cleanings, but they are not a replacement for a thorough mechanical sweeping. These products work best as a supplementary measure on first or light second-degree creosote and are not effective against heavy or glazed third-degree buildup. They should always be used in conjunction with, not instead of, professional annual sweeping.

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 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).

What are common chimney problems found during a sweep and inspection?

Several issues commonly arise during professional chimney inspections, including:

• Cracked or spalled flue tiles from heat cycling or chimney fires
• Deteriorated mortar joints in the firebox or exterior masonry
• A missing, damaged, or improperly sized chimney cap
• Crown cracking or deterioration allowing water penetration
• Blocked flues from debris, nesting animals, or collapsed liner sections

Many of these issues develop gradually and are not visible from inside the home, underscoring the value of professional annual inspection.
