Results are estimates from the numbers you enter and the assumptions described on this page; check them against local building codes, product specifications and current prices, and have structural, electrical or gas work designed or checked by a licensed professional.

How It Works

A reliable sweep estimate comes down to two things: what kind of chimney you have and how often it needs sweeping. Sorting that out in advance keeps your maintenance budget realistic and lets you weigh safety against expense before booking the work.

The estimate is a simple sum. Each cleaning is priced by fuel, $275 for a wood-burning fireplace or stove and $150 for a gas appliance, and multiplied by the number of cleanings per year you choose (one or two). A $125 annual inspection is then added to give the yearly total. The figures are fixed, with no regional adjustment, and they do not vary by inspection level, so a camera inspection or any repair has to be priced separately.

These numbers cover cleaning and inspection alone; any real repairs are billed on top. Putting off routine checks tends to be a false economy, since small issues left alone can grow into costly repairs and genuine safety risks. Pin down the exact scope of work with your chimney professional before they start.

Example: Wood-Burning Fireplace Swept Once a Year

  1. 1 Input: Chimney Type = Wood-Burning, Cleanings per Year = 1x per year.
  2. 2 Cleaning: $275 × 1 = $275. Annual inspection: $125.
  3. 3 Result: Annual Total = $400. Choosing 2x per year raises it to $275 × 2 + $125 = $675.
  4. 4 Context: NFPA 211 calls for chimneys, fireplaces and vents to be inspected at least once a year, and the Chimney Safety Institute of America advises sweeping a masonry fireplace once sooty buildup reaches 1/8 inch, sooner if there is any glaze. Structural issues or heavy creosote found during the inspection are quoted separately.

Frequently Asked Questions

How often should I have my chimney cleaned?
NFPA 211, the National Fire Protection Association's standard, says chimneys, fireplaces and vents shall be inspected at least once a year, with cleaning, maintenance and repairs done if necessary. The Chimney Safety Institute of America advises sweeping a masonry fireplace at 1/8 inch of sooty buildup, sooner if any glaze is present, and a factory-built fireplace whenever there is appreciable buildup. Chimneys serving gas appliances still need the yearly inspection, since nests and debris can block the flue.
How much does chimney cleaning cost?
This calculator uses $275 per cleaning for a wood-burning chimney and $150 for gas, plus $125 for the annual inspection, so one wood-burning sweep and inspection comes to $400 a year. Its figures do not change with inspection level; a camera inspection and repairs to liners, caps or masonry are quoted separately.
What are the signs that my chimney needs cleaning?
Warning signs include a strong odor from the fireplace, visible creosote buildup (black or brown residue), smoke entering the room instead of going up the chimney, and a damper that is difficult to open or close.
