Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterAnnual Sweep in Houston, TX
An annual chimney sweep in Houston, TX costs between $189 and $289 for a standard single-flue fireplace, and most homes in the area need it once a year or after every cord of wood burned. We book most annual sweeps within three to five business days, and every job gets a written price before the first tool comes off the truck. If you want the ballpark without the phone call, that’s the answer: budget roughly $189 to $289 for a clean, code-compliant sweep, with the final number depending on flue condition, creosote buildup, and whether you have a prefab or masonry fireplace.
Flint Chimney Co Houston performs this service as part of our broader Chimney Cleaning & Sweep in Houston work, and we run it under the same Garrison Standard that applies to every sweep, inspection, and repair we perform. Hank Delano, the owner, set the rule early: no vague verbal assurances, no pricing surprises at the door, and no crew dispatched who hasn’t passed a background check. That’s how we’ve operated since 2002 as part of the Garrison Partners family of independently owned chimney service companies.
Call (325) 750-6259 to schedule, or read on to understand exactly what an annual sweep involves, what it costs in Houston, and what we document in writing before and after the work.
When You Need an Annual Sweep in Houston
The short version: if you burn wood in your fireplace more than twice a month between October and March, you need an annual sweep. Houston’s humidity compounds the problem. The city sits in a humid subtropical climate, and the moisture that settles in your flue during the long damp spring and summer mixes with creosote residue, forming a sticky, acidic sludge that eats at mortar joints and accelerates flue deterioration. In neighborhoods like The Heights, Bellaire, and Kingwood, where hardwood burning is common and many homes still have original mid-century masonry chimneys, we routinely remove creosote that’s hardened to the consistency of road tar.
Here are the specific conditions that mean an annual sweep is due:
- You’ve burned a full cord of wood since your last cleaning. The National Fire Protection Association (NFPA 211) sets that as the trigger, and so do we. Most Houston homeowners who use their fireplace as a primary heat source in January and February hit that mark quickly.
- You see a quarter-inch or more of dark, flaky or glossy buildup on the flue walls. Shine a flashlight up past the damper. If the walls look fuzzy or glazed instead of brick-brown, that’s creosote. Glossy, tar-like creosote (what the trade calls “Stage 3” creosote) is a fuel source, not a cosmetic issue.
- Your fireplace smells like a campfire when you’re not burning. That odor is creosote off-gassing in Houston’s humidity, and it’s strongest in summer when the air handler pulls air down the chimney. We see this constantly in Memorial and Spring Branch homes that haven’t been swept in two-plus years.
- Smoke backs up into the room, even slightly, when you start a fire. That indicates restricted draft from creosote buildup, a bird nest, or a partially closed damper. Any of these needs eyes on it this season.
- You recently bought the home and have no record of a prior sweep. Houston’s older housing stock changes hands constantly, and we frequently find chimneys in Montrose and Garden Oaks that haven’t been cleaned since the previous owner stopped using the fireplace years ago.
- You’ve had a chimney fire, even a small one that burned itself out. Any chimney fire compromises flue integrity, and Houston code requires a professional inspection before the fireplace goes back into service. An annual sweep is the right follow-up after repairs.
Our Annual Sweep Process
Here’s how an annual sweep runs at Flint Chimney Co Houston, step by step. No shortcuts, no skipped corners, and every step documented on the invoice you approve before we begin.
- Written estimate before anything else. The technician arrives in a marked truck, in uniform, with a background-checked ID you can ask to see. Before setting up, we inspect the firebox, damper, and accessible flue, then hand you a written price for the sweep. That price is the price. If we find damage requiring repair, we show you photos and give you a separate written quote for that work. You decide; we don’t push.
- Interior protection and dust containment. We lay floor protection from the entry door to the hearth, drape the firebox opening, and run a HEPA-filtered vacuum system that captures soot and creosote at the source. We sweep chimneys in Houston homes with white carpet and antique furniture regularly, and the interior shows zero trace when we leave.
- Rotary brushing of the full flue length. We run professional-grade nylon or poly brush rods, sized to your flue diameter, from the firebox through the full length of the flue to the chimney cap. This removes creosote at all three stages: granular, flaky, and glazed. For heavy Stage 3 glazing, we’ll discuss chemical treatment options using products like Gelco creosote remover before resorting to anything more invasive.
- Smoke chamber and damper cleaning. The smoke chamber, the inverted funnel area above the firebox, collects as much creosote as the flue itself. We brush and vacuum it clean, then inspect and clean the damper assembly so it opens, closes, and seats properly.
- System check and written condition report. After the sweep, we inspect the flue walls, mortar joints, chimney cap, and crown from the roof (weather permitting). We document what we find in writing, including photographs, and staple that report to your invoice. If we see developing issues, like a cracked flue tile or rusting cap, we note it as “monitor” or “repair recommended” with no obligation attached.
- Cleanup and the 365-Day Done Right Promise. We remove the floor protection, vacuum the hearth area, and do a final walkthrough with you. If anything about the sweep is not right, that’s covered under our 365-Day Done Right Promise: a written guarantee, valid for one full year from the service date, with a free return visit if a covered issue arises. That’s the Garrison Standard, in writing, every time.
Annual Sweep Pricing in Houston
We publish our price ranges instead of hiding behind “call for quote” because you should know the ballpark before you pick up the phone. Here’s what an annual sweep costs in Houston as of 2026:
| Service | Price Range | What’s Included |
|---|---|---|
| Standard annual sweep, single masonry flue | $189 – $229 | Full flue brushing, smoke chamber clean, damper inspection, condition report |
| Standard annual sweep, prefab wood-burning fireplace | $199 – $249 | Full flue brushing, firebox clean, cap inspection, condition report |
| Heavy creosote service (Stage 3 glazing) | $289 – $389 | Extended brushing time, chemical treatment, follow-up inspection recommendation |
| Annual sweep with dryer vent clean (bundle) | $249 – $329 | Chimney sweep plus dryer vent cleaning, single visit |
What moves the price within these ranges? Flue height. A two-story chimney in a Memorial ranch costs more in labor and rod length than a single-story Cypress home. Creosote condition matters too, because glazed creosote takes longer to remove than flaky buildup. And if you have a multi-flue chimney (common in older Houston homes with a fireplace on each floor), that’s a separate flue, priced separately. We’ll tell you the number in writing before any work begins, and that number won’t change at the end of the job.
Call (325) 750-6259 for a free estimate, and we’ll give you the exact figure for your chimney over the phone or at the door before a single tool is picked up.
FAQs – Annual Sweep
How much does an annual chimney sweep cost in Houston?
An annual chimney sweep in Houston costs $189 to $289 for a standard single-flue fireplace. The exact number depends on flue height, creosote condition, and chimney type, and you’ll receive a written price before work begins. Call (325) 750-6259 for a free estimate specific to your home.
Is an annual chimney sweep really necessary if I only burn occasional fires?
Yes, if you burn more than two or three fires per season, an annual sweep is necessary because creosote, not frequency, is what builds the hazard. Houston’s humidity accelerates creosote hardening even in rarely used fireplaces, and NFPA 211 recommends annual inspection and cleaning as needed for any chimney in active use. We’ll tell you honestly if your fireplace doesn’t need a full sweep this year, and we’ll document that in writing either way.
Do you sweep chimneys the same day you inspect them?
In most cases, yes, because our inspection happens on the same visit as the sweep, not as a separate appointment. If we find the flue is clean enough to skip, we’ll say so. If it’s dirty, we sweep it right then, and you pay only the sweep price you approved before we started. Call (325) 750-6259 to book a time window that works for you.
What does the 365-Day Done Right Promise cover after an annual sweep?
If the sweep is not done right, we return at no charge within one full year of the service date and make it right. That includes anything from leftover creosote in the smoke chamber to a mess we missed. The guarantee is written on every invoice we hand you, and a free second visit is included if a covered issue arises, no charge and no argument.
Can I clean my chimney myself instead of paying for a sweep?
We don’t recommend it. A proper sweep requires specialized brushes sized to your exact flue diameter, a HEPA vacuum system to prevent fine soot and creosote dust from spreading through your Houston home, and roof access for a full inspection. More importantly, creosote removal is genuinely dangerous work: the dust is a lung irritant and a fire fuel. That’s why we train our technicians for this specifically. Call (325) 750-6259 and let a trained, insured professional handle it.
