Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterHow Much Does Chimney Cleaning Cost in Houston?
A standard chimney sweep in Houston typically runs $175 to $350 for a single flue, and most homes we service fall right around the $225 mark. If your sweep turns up creosote glazing, a cracked flue tile, or a nest blocking the pipe, expect to add inspection or repair charges on top of that base price. Same-day and next-day appointments are almost always available in Houston during the off-season months of March through September.
We’re Alcott Chimney Sweep, founded in 2002 and part of the Threshold Group family of home-service companies. We’ve cleaned Houston chimneys long enough to know that the price you’re quoted on the phone is the price you should pay at the door. That’s why every customer gets a written price before any work starts.
If you want an exact number for your specific house, call (336) 863-3889 and we’ll give you a real range on the call, not a vague “we’ll see when we get there.”
Chimney Cleaning Cost Breakdown (2026)
Here’s what Houston homeowners actually pay for the most common chimney services in 2026. These ranges cover single-flue wood-burning fireplaces, which is what we see in the majority of Houston homes.
| Service | Typical Houston Price (2026) |
|---|---|
| Standard chimney sweep (single flue) | $175 – $350 |
| Two-flue sweep (common in older Heights and Montrose homes) | $300 – $525 |
| Level 1 inspection (included with most sweeps) | $0 – $125 (often bundled) |
| Level 2 inspection (camera scan, needed for home sales or after a chimney fire) | $225 – $450 |
| Creosote removal, stage 3 (glazed, hardened tar) | $450 – $1,200+ |
| Animal nest or debris removal (birds, squirrels, raccoons) | $150 – $400 |
| Chimney cap installation (stainless, single flue) | $175 – $400 |
| Flue liner replacement (per foot, DuraFlex system) | $75 – $150 per linear foot |
| Crown repair or rebuild | $350 – $1,400 |
| Gas fireplace service and repair | $150 – $500 |
The base sweep is the entry point, and for most Houston homes it’s the only line item you’ll pay. What pushes the ticket above $350 is almost always one of three things: a second flue, hardened creosote that has to be physically scraped rather than brushed, or damage discovered during the sweep that needs a repair quote before we can safely call the job done.
The single most important thing we do for you is put the price in writing before we start. No surprise number at the end. If we find something during the sweep that changes the scope, we stop, show you what we found, and give you a written price for the repair before we continue. That’s the standard, not a favor.
What Affects Chimney Cleaning Pricing in Houston
Chimney pricing in Houston isn’t random. A few specific factors move the number up or down, and knowing them lets you predict your own bill before you call.
- Number of flues. A single-flue fireplace is a one-price job. Houston has a lot of older two-flue homes in the Heights, Montrose, and Near Northside, and each additional flue adds $125 to $175 to the ticket because it’s a full separate sweep with its own brush, rods, and cleanup.
- Creosote stage. Creosote is the tar-like buildup that causes chimney fires, and it comes in three stages. Stage 1 is a soft, flaky soot that brushes off easily. Stage 2 is a hard, shiny crust that takes a rotary brush. Stage 3 is glazed, hardened tar that requires chemical treatment and can push a job past $1,000. Houston’s humid climate and our heavy oak and pecan firewood supply tend to produce more stage 2 buildup than you’ll see in drier markets, so we inspect the flue before we quote.
- Chimney height and roof access. A one-story ranch in Bellaire is an easier, faster sweep than a steep-pitch two-story in River Oaks. Anything above 30 feet, or anything with a steep roof pitch, takes longer and prices in a few extra hours of labor.
- Obstructions. Houston’s tree canopy is one of the densest in the country, and that means we pull squirrel nests, bird nests, and leaf pack out of flues on a regular basis. When a flue is blocked, the sweep can’t be completed until the obstruction is cleared, and that’s a separate line item.
- Masonry condition. If the flue tiles are cracked, spalling, or missing mortar joints, we can’t safely sweep without addressing it. A cracked tile that would let heat reach the framing behind the chimney is a real fire risk, and it’s the most common reason a routine sweep turns into a repair visit.
- Time of year. September through December is peak season in Houston, and pricing reflects that. If your chimney only needs a routine sweep and you don’t burn until the first cold front, March through August is the cheapest window and the easiest time to get same-day service.
One more local factor worth knowing: Houston homes sit close to the Gulf and the humidity doesn’t take a season off. That moisture moves into masonry, and masonry that stays damp breaks down faster than the same chimney in, say, Amarillo. Chimneys here benefit from a stainless chimney cap and a properly sealed crown, and both of those are affordable add-ons during a sweep that save real money later.
What a Chimney Sweep Actually Includes
Before you compare prices between companies, it helps to know what a real sweep involves, because the cheapest quote is often the one that skips a step.
A proper sweep at our company includes a drop cloth and full work-area protection, a brush-and-rod cleaning of the full flue from the roofline to the firebox, removal of all soot and debris from the smoke chamber and firebox, a level 1 inspection of the accessible portions of the chimney, and a written summary of what we found. We use professional trade equipment and products. When a flue needs resurfacing, we use HeatShield. When a liner needs replacing, we install DuraFlex systems, and we carry Gelco, Olympia Chimney, Famco, and Copperfield parts because those are the brands chimney professionals specify, not the box-store substitutes that fail early.
What you should ask any company before booking: do they provide a written price before work begins, do they carry general liability insurance, and will they show you photos of what they found inside the flue. If the answer to any of those is “no” or “we don’t usually,” that’s your signal to keep looking.
Safety note worth being blunt about: chimneys carry combustion gases and creosote is genuinely flammable. We don’t recommend homeowner flue cleaning with a hardware store brush. The tools are cheap, but the risk of dislodging a chunk of creosote onto a hot smoke shelf, or of falling off a Houston roof while trying to reach a chase top, isn’t worth the $200 you saved. This is work you hire out.
How to Save on Chimney Cleaning
There’s no coupon stacking required. A few practical habits keep the annual cost at the low end of the range.
- Book in the off-season. Call in April or May instead of October. You’ll get the low end of the range and same-day scheduling.
- Bundle the sweep and inspection. When a sweep includes a level 1 inspection at no extra charge, which is standard for us, you’re effectively getting two services for the sweep price.
- Burn seasoned wood. Green or unseasoned firewood produces far more creosote than wood that’s dried for a year. Dry hardwood means your sweep stays in the $200 range instead of climbing toward a stage 3 removal.
- Keep the cap in good shape. A $175 to $400 stainless cap keeps rain, leaves, and animals out of the flue. Skipping it regularly costs more in obstruction removal than the cap would have cost in the first place.
- Address small cracks early. A $350 crown repair now is far cheaper than a $1,400 rebuild or liner replacement later, and Houston’s humidity is the reason masonry here deteriorates faster than it does in dry markets.
- Ask for a free estimate. We give real ranges on the phone and a written price before work starts. Call (336) 863-3889 and we’ll quote your house specifically rather than reading a generic schedule.
If your home has been through a chimney fire, even a small one you put out yourself, skip the discount shopping and get a level 2 inspection with a camera. A fire can crack tiles behind the visible flue, and you won’t see it without a camera scan.
Why Houston Homeowners Choose Alcott Chimney Sweep
Most chimney companies compete on price. We compete on certainty, because the thing our customers actually worry about isn’t the $225. It’s who’s coming to the house.
Every technician who shows up at your door has passed a background check and identity verification before ever stepping on your property. This is the Threshold Standard, and it isn’t an optional upgrade. You’ll get the technician’s name and a photo before we arrive, and they’ll show a photo ID badge at the door. Every visit. No exceptions.
Every job comes with a written price before work begins and a written guarantee on every repair. If a repair fails within the coverage period, the second visit is free. And every completed job is backed by our 365-Day Done Right Promise. A full year of accountability on the work we did.
Our phones are answered by a live person around the clock. If something smells like smoke at 11 p.m. in Katy, you’re talking to a person, not a voicemail. That matters more than most homeowners realize until they need it.
We’ve been serving homeowners since 2002 as part of the Threshold Group family of home-service companies, and Houston is one of the markets we know best. If you want to compare what we do against the basics, start with our main home page, then look at our chimney services and nearby city guides for the same honest pricing we publish here.
Chimney Cleaning and Inspection: Where the Money Goes
One question we get a lot: why does an inspection cost anything at all if the sweep already includes a look at the flue? The answer is scope.
A level 1 inspection, which most sweeps include, covers the readily accessible parts of the chimney: the firebox, damper, smoke chamber, and the flue as far as we can see from the top and bottom. It’s enough to catch most problems.
A level 2 inspection adds a video camera scan of the full flue interior, inspection of the attic and crawl space where the chimney passes through, and a look at the connected appliance venting. It’s required in most home-sale transactions, after a chimney fire, after an earthquake or major storm, or when you’ve changed the type of fuel you burn. In Houston, we recommend a level 2 any time a house changes hands, because sellers rarely have documentation of the last inspection.
The difference in price, $225 to $450 versus a bundled level 1, is worth it in exactly those situations. For a routine annual sweep on a chimney you’ve maintained, level 1 is fine.
FAQs – Chimney Cleaning Cost
How much does a chimney cleaning cost in Houston?
A standard single-flue chimney sweep in Houston costs $175 to $350 in 2026, with most jobs landing near $225. Two-flue homes run $300 to $525. Anything above that range means we found creosote glazing, an obstruction, or masonry damage that requires a separate written quote before we continue. Call (336) 863-3889 for a free estimate specific to your house.
Is it cheaper to clean a chimney myself?
Only if you already own the rods, brushes, drop cloths, and safety gear, which together run $150 to $300, and only if you’re comfortable working on your roof. By the time you buy the equipment and spend a Saturday on it, you’ve matched the cost of a professional sweep without the inspection, the disposal, or the guarantee. Add the real risk of injury on a Houston roof and the math stops making sense. Call (336) 863-3889 and let a trained, background-checked technician handle it.
How often does a Houston chimney need cleaning?
Once a year for most homeowners, or after every cord of wood burned, whichever comes first. Houston’s humidity and dense tree canopy mean obstructions and moisture damage show up faster here than in drier parts of Texas, so annual is the right cadence. If you burn more than two cords a season, or you notice a strong smoky smell in the house when the fireplace isn’t in use, schedule a sweep before the next burn.
Can you clean my chimney the same day I call?
Usually, yes. Same-day and next-day appointments are standard for us during March through September, and we keep space in the schedule year-round for urgent calls. Peak months of November and December may book out a few days. Our phones are answered by a live person 24/7, so call (336) 863-3889 whenever it occurs to you and we’ll find the earliest slot that works.
What does the written guarantee actually cover?
Every repair we make comes with a written guarantee, included at no extra charge. If the repair fails within the coverage period, we come back and make it right at no cost to you. On top of that, every completed job is covered by our 365-Day Done Right Promise, a full year of accountability on the work. The guarantee terms are written down and given to you before we leave, so there’s nothing vague about it. Call (336) 863-3889 if you’d like to see the exact wording before you book.
If you’d rather just get a number, that’s the fastest path. Call (336) 863-3889 and tell us the number of flues, the neighborhood, and whether the chimney has been cleaned in the last two years. We’ll give you a real range on the call, then a written price before any work starts. No voicemail, no callback queue, and no surprise charges at the end. Estimates are free, and so is the phone call.
