How long does a chimney sweep appointment take from start to finish?
Short answer. Most chimney sweep appointments take about one to two hours from arrival to written report for a single fireplace flue. A basic Level 1 inspection with cleaning is the quick version; a Level 2 inspection with a camera scan, typical when buying a home or changing appliances, takes longer.
The visit, step by step
- Walkaround and questions. What you burn, how often, and any smoke, odor or water problems.
- Setup. Drop cloths, a sealed fireplace opening and a vacuum running.
- Cleaning. Brushing the flue, smoke chamber, smoke shelf and firebox.
- Inspection. Checking the damper, liner, firebox and accessible exterior.
- Report. Photos or video, a written summary and any recommended repairs.
Inspection levels and time
NFPA 211, the national standard for chimneys and fireplaces, describes three levels of inspection:
- Level 1: readily accessible parts, for chimneys in continued use with no changes. It fits inside a normal cleaning visit.
- Level 2: adds accessible attic, crawlspace and exterior areas plus a video scan of the flue. It is called for when a home is sold, the appliance or fuel changes, or after a chimney fire or major storm. Expect a longer visit.
- Level 3: removes parts of the building or chimney to reach concealed areas, only when a serious hidden problem is suspected. That becomes a separate project.
Before and after
- No fires for at least 24 hours before the visit.
- Ask whether the sweep works from the roof, and if so, for photos of the crown, cap and flashing.
- Keep the report. Exterior items like flashing gaps, crown cracks or soft roofing near the chimney are roofer work.
