How Long Does a Chimney Cleaning Take?
Most routine sweeps take under an hour — but a few specific factors can stretch that out.
A Typical Routine Sweep
For a chimney that's been cleaned within the last year or two, expect around 45 minutes to an hour, including setup and cleanup.
What Adds Time
Heavy creosote buildup, a chimney that hasn't been cleaned in several years, difficult roof access, or discovering an animal nest all extend the visit.
If an Inspection Is Included
Combining a sweep with a full inspection adds time, since the technician is also checking the liner, crown, and structural condition, not just clearing buildup.
What Happens If Something Unexpected Turns Up
If a real issue is found mid-cleaning (significant damage, a serious blockage), the technician should stop and discuss it with you rather than just pushing through — which can extend the visit but is worth the pause.

Frequently Asked Questions
Do I need to be home the whole time?
It's generally a good idea, especially for a first visit, so the technician can walk you through anything they find.
