Exceptional Windsor Chimney Sweeping

COMMON QUESTIONS

chimney sweeping FAQS

What should I expect from a real-estate chimney inspection?

Expect a Level 2 inspection rather than a basic yearly walkthrough. That means a more complete look at the flue and accessible areas around the chimney, often with video, and a written summary of findings. If creosote or blockages are present, a sweeping can often be done in the same appointment. Windsor sellers and buyers can use the report to understand the system’s condition. CSIA-certified technicians can also explain whether anything they find needs a closer Level 3 look.

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.

Will the technician need access to the roof, the fireplace, or both?

Most appointments start at the fireplace, and many cleanings can be done from the firebox with the right brushes, rods, and vacuum. Roof access may still be needed to inspect the crown, cap, and flue opening, or to clean from the top when the system requires it. The technician will use the approach that lets them clean and inspect the system thoroughly and safely. If roof access is difficult, mention it when you book so the visit can be planned accordingly.

What does a CSIA-certified chimney sweep look for during a visit?

A CSIA-certified technician looks at how the system is drafting, whether creosote or debris is present, and whether accessible parts of the flue, firebox, cap, and damper appear intact. The visit follows NFPA 211 practice: inspect at least annually and sweep as needed. The technician also watches for signs of moisture, blockage, or prior overheating and will explain anything that should be repaired or inspected more closely. You should leave with a clear sense of the chimney’s condition, not just a cleaned flue.

How is a wood-burning flue swept differently from a gas vent? 

The tools and the amount of cleaning differ because the deposits differ. Wood systems need a mechanical sweeping when creosote has built up. Gas systems are checked for blockages, damage, and safe venting, with cleaning as needed rather than a heavy creosote sweep. Windsor homeowners should not treat a gas visit as optional just because it is usually a lighter cleaning. Mention the fuel type when you book so the technician brings the right equipment.
