Quick AnswerA standard single-flue chimney sweep with a full inspection costs $199 flat at The Chimney Sweeper, with no separate inspection fee, travel fee or creosote surcharge. Published US ranges for the same job are $150 to $375 (HomeGuide, February 2026) and $129 to $381 with an average of $254 (Angi, July 2026). Price rises with the number of flues, roof access, creosote stage and chimney type. Repairs are priced separately, in a written estimate, before work starts.

Why “Starting At” Pricing Often Balloons
If you’ve called around, you’ve probably noticed the advertised number rarely matches the final bill. That gap usually comes from a handful of predictable add-ons:
- A separate inspection fee. Some companies quote the sweep alone and charge extra for the inspection that should come with it.
- Travel or trip fees. A flat "service call" charge added on top of the advertised price, sometimes disclosed only after booking.
- Creosote-stage surcharges. An extra charge once the technician is on the roof and finds heavier buildup than the base price assumed — sprung on you after the truck has already arrived.
None of that means the work isn’t worth paying for. It just means the number in the ad and the number on the invoice can be two very different things unless the company commits to a flat rate up front.
What Legitimately Affects Sweep Pricing
Some price variation is completely reasonable — it just reflects real differences in the job, not a bait-and-switch. The factors that actually matter:
- Number of flues. A chimney venting a fireplace and a furnace through separate flues takes more time to sweep and inspect than a single-flue chimney.
- Height and accessibility. A steep roofline, a tall chimney, or difficult ladder access takes longer and requires more setup than a straightforward one-story home.
- Level of creosote buildup. A chimney that hasn’t been swept in several years takes more time and effort to clean than one on a regular annual schedule.
- Masonry vs. prefab/metal chimney. Factory-built metal chimneys and traditional masonry chimneys use different tools and techniques, which can affect the time and equipment involved.
Chimney and appliance type is the factor the national cost publishers quantify most consistently. Their published ranges for each type:
| Chimney or appliance type | HomeGuide, February 2026 (USD) | Angi, July 2026 (USD) |
|---|---|---|
| Masonry wood-burning fireplace | $150–$375 | $129–$381 |
| Gas fireplace | $80–$150 | $80–$130 |
| Factory-built (prefabricated) chimney | $90–$175 | — |
| Wood stove or insert | $130–$300 | $150–$300 |
| Pellet stove | $130–$300 | $130–$200 |
Sweep Pricing vs. Repair Pricing
It’s worth separating these two categories entirely, because they work differently. A routine sweep and inspection is a predictable, bounded job — which is exactly why it lends itself to flat-fee pricing. Repair work is the opposite: fixing a cracked crown, replacing a damaged cap, relining a flue, or rebuilding a chase can range from a small, quick fix to a major masonry project, and the price spread between those is enormous. That’s why any legitimate company should treat repair pricing as its own conversation, with its own written estimate, rather than folding a guess at repair costs into the sweep price. Inspection pricing works the same way and is set by the inspection level the standard calls for, which is worth understanding before you compare quotes.

Our Approach: Flat Fee, Written Estimate Before Any Repair
This is the whole philosophy behind how we price things. Our winter special is a flat $199 for a full sweep and inspection on a standard single-flue chimney — the price you see is the price you pay, with no inspection fee, no travel charge, and no surprise creosote surcharge tacked on once we’re on the roof. If the inspection turns up something that needs repair, we show you what we found, walk you through it, and put together a written estimate before any repair work starts. Nothing gets added to your bill without your sign-off first.
FAQs
A low headline price often excludes the inspection, travel, or a basic sweep of a lightly-used flue, with extra line items added once the technician is on site. Ask upfront whether the quoted price is the total price or a starting point before extras.
Yes. The $199 winter sweep includes a full rotary sweep and a complete visual inspection of your flue, firebox, and damper for a standard single-flue chimney. If the inspection reveals repair needs, those are quoted separately in writing before any work begins.
It depends entirely on scope, from a simple cap replacement to a full crown rebuild or reline, so we don’t quote repairs sight unseen. You’ll always get a specific written estimate based on what our technician actually finds, and you decide whether to move forward before any repair work starts.
