The honest breakdown of chimney cleaning costs

Chimney cleaning — also called chimney sweeping — removes the creosote, soot, and debris that build up inside your flue every time you burn wood. Skipping it isn’t just messy; creosote is the leading cause of chimney fires, with the U.S. Fire Administration reporting over 22,000 chimney fires per year in the United States.
‍
The national average for a professional chimney cleaning sits between $179 and $450, but the final price depends on a handful of practical factors: the type of fireplace you have, how many stories tall your home is, how long it’s been since the last cleaning, and whether the tech finds problems that need attention (cracked crowns, missing caps, glazed creosote).Brown Chimney has been sweeping flues for over 20 years. The calculator below uses the same line-item pricing our techs use in the truck — no bait-and-switch, no inflated quotes.

What drives the price

4 factors that change your cost

Fireplace type

$189 – $349

Open masonry, fireplace inserts, wood/pellet stoves, and prefab metal each require different brushes, rods, and sealing. Inserts take longest because the unit often has to come out.

Home stories & roof access

+$0 – $90

1-story homes are quickest. Steep roofs, 2-story (+$40) and 3-story (+$90) homes need taller ladders, fall protection, and extra setup time on the roof.

Time since last cleaning

+5% – 35%

A flue cleaned every year is fast. After 3+ years (or 'never'), creosote layers thicken into Stage 2 or Stage 3 glaze that takes longer to remove and may need chemical treatment.

Found issues & add-ons

+$49 – $200

Heavy creosote removal (+$95), animal/nest extraction (+$75), and cap & crown inspection (+$49) are common add-ons quoted before any extra work begins.

Drop-cloth & HEPA vacuum protection

Full flue sweep (base to cap)

Smoke chamber & firebox cleaning

Ash & debris removal

Visual safety inspection

Written report with photos

FAQ

Chimney cleaning cost — common questions

How much does chimney cleaning cost on average?

Most homeowners pay between $179 and $450 for a professional chimney cleaning. The price depends on the type of fireplace, home stories, accessibility, and how much creosote or debris has built up since the last cleaning.

How often should a chimney be cleaned?

The CSIA and NFPA 211 recommend a Level 1 inspection every year. Cleaning is required when the creosote layer reaches 1/8" (about 3 mm) or sooner if you burn 3+ cords of wood per year, burn unseasoned wood, or notice odors and slow-drafting fires.

What is included in a standard chimney sweep?

A standard sweep includes drop-cloth and HEPA-vacuum protection, brushing of the flue from base to cap, smoke chamber and firebox cleaning, ash removal, and a visual safety inspection of the damper, liner, and crown.

Why is chimney cleaning more expensive for 2-story or 3-story homes?

Multi-story homes require taller ladders, roof harnesses, and more time on the roof for cap removal and top-down brushing. Add roughly $40 for 2-story and $90 for 3-story access on top of the base price.

Do you offer a free estimate before the cleaning starts?

Yes. Our techs provide a written, on-site estimate before any work begins. The price you see in our calculator is the same range we quote — there are no hidden fees.

What happens if you find a problem during the inspection?

If we find creosote glaze, a cracked liner, a damaged crown, or other safety issues, we'll show you photos and provide a separate written quote. We never start additional work without your approval.
