chimney sweeping FAQS

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).

Should I close my damper when the fireplace is not in use?

Yes – always close the damper when the fireplace is not in active use. An open damper acts like an open window, allowing conditioned air to escape and cold drafts to enter, which can significantly increase heating costs. A closed damper also prevents animals, insects, and debris from entering the flue, though a properly installed chimney cap provides the first line of defense and allows the damper to serve as a secondary barrier.

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.

How can I tell if my chimney has a draft problem?

Signs of a draft problem include smoke entering the room when the fireplace is in use, difficulty lighting or maintaining a fire, persistent odors from the fireplace when it is not in use, and cold air drafts coming down the chimney. Draft issues can be caused by a blocked flue, a closed or faulty damper, negative air pressure in the home, an undersized or oversized flue, or structural problems with the chimney. A certified sweep can diagnose the cause and recommend the appropriate remedy.

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

• 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 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.
