Chimney costs
How much does a chimney inspection cost?
The level decides the price, and most people are quoted for the wrong one. Level 1 is often free with a sweep.
Level 1 is usually free with a sweep. Level 2 runs $250 to $500 because it is a different visit.
Chimney inspection cost is decided by which of the three NFPA levels your situation calls for, not by which company you ring. A Level 1 is a visual check and most reputable firms include it with an annual cleaning at no extra charge — if yours bills separately for it, ask what it adds. A Level 2 adds a video scan of the full flue plus attic and roof access, and that is real extra work: one to two hours, camera equipment, and a written report. Level 3 involves opening up structure and is quoted per job because no two are alike.
What you are buying
A camera, or a torch
The camera is the whole difference between a Level 1 and a Level 2, and everything expensive lives inside the flue.

Chimney inspection cost by NFPA level
Every figure here is a band, because a single number for work nobody has looked at yet would be a guess dressed up as a quote.
| The job | Typical range | What moves it |
|---|---|---|
| Level 1 with an annual sweep | $0 — included | Should not be billed separately |
| Level 1 on its own | $100–$180 | An hour, no specialist equipment |
| Level 2 — sale, appliance change, after a fire | $250–$500 | Camera, attic and roof access, written report |
| Level 2 with a sweep first | $400–$700 | A sooty flue hides what the camera looks for |
| Video scan on its own | $150–$300 | Flue only, no attic or roof |
| Level 3 — opening up structure | Quoted per job | How much has to come apart |
US-wide bands for planning, not a quote. Regional labour rates move all of these, and the only number that means anything is a written estimate for your chimney.
What actually decides the number
Which level the situation calls for
The biggest factor by a distance. A property sale, an appliance change or a suspected chimney fire all require a Level 2, and no amount of shopping around turns that into a Level 1.
Whether the flue needs sweeping first
Creosote hides exactly what a level 2 camera is there to find. Most chimneys need cleaning before a scan is worth doing, and booking both together costs less than two visits.
How many flues the stack serves
Older houses often run two or three. Each is scanned separately, because a breach between two flues is precisely the fault this finds.
Whether you need a documented report
A verbal all-clear costs nothing and is worth nothing in a negotiation or a claim. Written findings with footage take time to produce and are priced accordingly.
Turnaround
Transactions run to closing dates. A report needed in two days rather than a week is a scheduling cost, and it is fair to be told so up front.
Should be included
- A walk of the exterior masonry, crown and cap
- Firebox, damper and smoke chamber where visible
- A check that the flue is clear of obstruction
- Findings in writing, whatever they are
- Photographs of anything called out
Priced separately
- The sweep, if the flue needs cleaning before a scan
- Level 2 camera work, if you booked a Level 1
- Attic and crawl space access on a Level 1
- Any repair the inspection recommends
- A second scan after work is done — ask whether it is included
Quotes to walk away from
- A Level 1 priced anywhere near a Level 2. They are not close in work and should not be close in price.
- A reline or rebuild recommended without footage you can keep and look at again.
- No written report offered, especially when the reason for the visit is a sale or a claim.
- A scan performed on a flue that was visibly sooty, then reported clear.
- An inspection that is free with no conditions and arrives with a repair quote already written.
The VIO Standard
- A written estimate first
- License and insurance checked
- Nothing starts without your OK
Common questions
Should a chimney inspection cost extra on top of a sweep?
Generally not. Most reputable companies include the Level 1 with an annual cleaning, because someone is already there with eyes on the system and it takes minutes rather than hours. If a company bills separately, that is not automatically wrong — but it is fair to ask exactly what the inspection adds beyond what the sweep already involved, and to expect written findings for the money.
Why does a Level 2 chimney inspection cost so much more?
Because it is a different job rather than a longer version of the same one. It adds a video camera run through the entire flue, physical access to the attic, crawl space and roof where the chimney passes through, and a written report with footage attached. That is one to two hours on site plus equipment plus report time. Against the cost of discovering a failed liner after a closing, it is not a large number.
How much is a chimney inspection for buying a house?
You want a Level 2, and $250 to $500 is the usual band before sweeping. Budget for the sweep as well, because a sooty flue hides what the camera is looking for and any honest company will say so. It is worth putting in perspective: a cracked liner is a multi-thousand-dollar item that does not appear in a general home inspection, and this is the only thing that finds it before you own it.
Is a free chimney inspection worth having?
Sometimes, and read the conditions. A free Level 1 bundled with a paid sweep is normal and fine. A free standalone inspection from a company whose revenue is repairs is a sales call, and the tell is whether you are handed written findings with photographs or a quote. Ask for the documentation before booking; the answer tells you which of the two you are getting.
Does chimney inspection cost more for multiple flues?
Yes, and it should. Each flue is scanned separately, because the camera can only be in one at a time and a breach between two flues in the same stack is exactly the fault this is looking for. Expect an increment per additional flue rather than a doubling — the access and setup are already paid for by the first.

The only number that counts is the one for your chimney.
Ranges are a starting point. A written estimate after someone has looked at it is the real answer, it costs nothing to ask for, and you are not committed to accepting it.
