Chimney Sweep Business
Nobody calls a sweep because the chimney is dirty — they call because they smelled smoke in the living room, and that means they all call in the same eight weeks.
The numbers that matter
$150–$350 a sweep. 45–90 minutes on site.
The camera inspection you add to that same stop is $250–$500 and takes another 25 minutes.
Which is why the year is decided by how many stops you can reach between September and December.
Three-quarters of the year's money arrives in fourteen weeks
This is the most seasonal trade on this site, and it isn't close.
Your phone is a fire alarm that goes off the first cold week and goes silent in April.
You already know this part — what most sweeps never do is put a number on it and plan the other 38 weeks against that number.
The shape of a sweep's year — Asheville, NC
One sweep runs one van. Between September 14 and December 22 they booked 213 jobs at an average ticket of $245, which is $52,185. From January through August they booked 61 jobs for $14,945.
78 cents of every dollar they earned arrived in 14 weeks. They could not add a 214th job in November, because there was no November left.
So in July they text last year's list one line: "Booking September now — call this week and you're on the calendar before the weather turns. In October I'm six weeks out." That text moves roughly 40 jobs from their impossible month into their empty one.
The certification nobody requires and everybody asks for
Most states do not license chimney sweeping as a trade.
That changes the moment you stop sweeping and start relining, rebuilding a crown or repointing a stack, which in many states and cities falls under contractor registration or a home improvement license — rules vary by state and city, so confirm with your state licensing board before you quote repair work.
Meanwhile the people who send you work have made up their own rule.
Insurance adjusters, real estate agents writing a repair addendum, and municipal inspectors increasingly ask for a certified sweep by name, and the Chimney Safety Institute of America credential is the one they name.
Being the only certified sweep on an agent's referral list wins jobs that never go out to bid, which is worth more than the exam costs. Check csia.org for current requirements, fees and renewal cycle.
What a stop is worth, line by line
| Job | Time | Typical price |
|---|---|---|
| Standard sweep, open fireplace | 45–90 min | $150–$350 |
| Wood stove or insert sweep | 60–120 min | $200–$400 |
| Level 1 inspection with sweep | included | $0–$100 |
| Level 2 camera inspection | 45–90 min | $250–$500 |
| Chimney cap, supplied and fitted | 30–60 min | $250–$650 |
| Glazed creosote removal | 2–5 hr | $500–$1,400 |
| Crown repair or sealing | 2–4 hr | $300–$900 |
| Dryer vent cleaning | 30–45 min | $110–$220 |
Notice that the two lines that pay best per minute are the camera and the cap, and both happen on a stop you already drove to. More on charging for the second thing while you're standing there is in the pricing guides.
The camera pays for itself in eleven stops — Dayton, OH
A $189 sweep on a 1962 masonry chimney. Halfway through, the camera finds a cracked clay flue tile behind a smoke stain the homeowner had been painting over for two years.
The Level 2 inspection is $275, the written report goes to her insurer, and the relining quote that follows is $3,400. One stop: $464 in 2 hours 10 minutes, or $214 an hour — against $189 and 55 minutes if he'd swept and left.
What he says on the ladder: "I'm not going to guess what's behind that stain. A camera scan is $275 and you keep the photos and the report whether or not you hire me to fix it."
What you actually need before your first fall
- A HEPA-rated vacuum, $700–$1,600. A shop vac blows soot through a customer's living room, and one of those calls costs more than the vacuum.
- Rotary sweeping system, $600–$1,300. Poly heads for metal liners, wire for masonry. Using the wrong one scores a stainless liner.
- An inspection camera, $900–$2,600. This is the tool that turns a $189 stop into a $464 one. Buy it in year one, not year three.
- Roof access you're willing to use in November. Ladder, stabilizer, roof harness and anchor. Falls, not fires, are what end sweeps' careers.
- General liability plus care, custody and control. You are working over a customer's carpet and inside an appliance that burns.
- CSIA certification. Not required by law in most places. Asked for by insurers, agents and inspectors anyway.
- Contractor registration if you'll do repairs. Relining and masonry cross into licensed work in many states and cities — check your state licensing board first.
- A written summer plan. Dryer vents, caps, crowns and relines booked out of the fall backlog, or you will spend April eating your December.
You are the last professional who touched that chimney. Sweep it, hand over cash, leave nothing in writing, and if there's a chimney fire in February you have no record of what the flue looked like when you were standing in it. Every stop gets a written report — condition of the flue, the damper, the crown and the cap, photographs of anything you flagged, and the customer's signature or an emailed copy. It takes 6 minutes. It is the cheapest insurance in this trade, and it is also what makes the repair sale later.

Common questions
How much does a chimney sweep charge per job?
$150 to $350 for a standard open-fireplace sweep, 45 to 90 minutes on site. Wood stoves and inserts run $200 to $400 because the appliance comes apart. A camera inspection is a separate $250 to $500.
Do you need a license to be a chimney sweep?
Most states don't license sweeping itself, but relining and masonry repair often fall under contractor registration or a home improvement license. Rules vary by state and city — confirm with your state licensing board before quoting repairs.
Is CSIA certification worth it?
It isn't legally required in most places and it still pays for itself. Insurers, real estate agents and inspectors ask for a certified sweep by name, and referral lists are worth more than bid work. See csia.org for current requirements and renewal.
How much does it cost to start a chimney sweep business?
Roughly $4,000 to $9,000 in equipment if you already have a van. HEPA vacuum $700–$1,600, rotary sweep system $600–$1,300, camera $900–$2,600, plus ladders, fall protection, drop cloths and insurance.
What do chimney sweeps do in the summer?
Dryer vents, caps, crowns, flashing, masonry and the relining work booked out of the fall inspection backlog. Repairs happen in July because nobody wants their fireplace out of service in December.
How many chimneys can you sweep in a day?
Four to six standard sweeps solo, counting drive time, setup, cleanup and the report. Adding a camera inspection to a stop you already drove to takes 20 to 30 minutes and pays better than finding a sixth address.
Pull last year's customer list this week and count how many of them booked in October. Text that group in July instead, and see how much of December you can move into September.
Ranges here are compiled public ranges for solo chimney sweeps as of August 2026 — a starting point, not a quote or a survey result. Certification requirements and licensing for repair work differ by state and city; confirm on your state's official site and at csia.org before acting.
