Terms of Service
Last updated: September 27, 2026
Estimates and pricing
Prices quoted by phone for sweeps, inspections and duct cleaning are flat prices for the scope described. If the situation on site is materially different from what was described (for example additional flues, a second HVAC system, or Stage 3 creosote), we will explain the difference and quote the change before doing any additional work. Repair estimates are written, itemized and valid for 30 days.
Scheduling
We confirm appointment windows by phone or text. Please make sure the fireplace has not been used for at least 24 hours before a sweep, that the areas around the fireplace, furnace and dryer are accessible, and that pets are secured. If we cannot access the work area, a return visit may be charged.
Payment
Payment is due when the work is complete, unless a written agreement says otherwise. We accept cash, check and major credit cards. Larger repair projects may require a deposit for materials.
Workmanship guarantee
We stand behind our work. If a service we performed is not right, tell us and we will come back and make it right. Manufacturer warranties on products such as liners, caps and dampers are passed on to you. Our guarantee does not cover pre-existing conditions, damage caused by others, or problems that arise from not following the recommendations in your report.
Inspections and reports
Inspection reports describe the condition of the accessible parts of the system on the day of the inspection, to the level of inspection performed. A Level 1 inspection does not include concealed areas; a Level 2 includes a camera scan of the flue. Reports are for the customer's use and are not a guarantee of future performance.
