Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Trusted Chimney Sweep for Houston Homeowners
A chimney sweep in Houston typically costs between $149 and $299 for a standard cleaning and inspection, and most jobs take under two hours from setup to final vacuum. Flint Chimney Co Houston has been doing this work since 2002 as part of the Garrison Partners family, which means every sweep includes a written price before we start and a 365-Day Done Right Promise in writing. For a full guide on what to expect, see our Chimney Sweep Maintenance Checklist for Houston Homeowners. Hank Delano runs our Houston operation, and his rule is simple: no surprises, no upsell, no mess left behind. Call (325) 750-6259 and a live person answers, any hour, any day.
Chimney Sweep Services
Our Chimney Sweep in Houston covers the full cleaning of your flue, smoke chamber, damper, and firebox, removing creosote and soot that build up from regular fires. Houston’s humid climate makes creosote stickier and faster to accumulate than in drier regions, which means even light fireplace use can create deposits worth addressing annually. We sweep the entire system using rotary brushes sized to your flue, then run a camera inspection so you see exactly what we saw. A standard sweep with inspection runs $149 – $299 depending on flue height, accessibility, and how long it has been since the last cleaning.
Creosote Removal
Creosote is the tar-like residue left behind when wood smoke cools inside your chimney, and it is the leading cause of chimney fires in Houston homes. We remove Stage 1, Stage 2, and glazed Stage 3 creosote using mechanical and chemical treatments appropriate to the buildup. You get a camera-verified before and after so the result is documented.
Smoke Chamber Cleaning
The smoke chamber sits between the firebox and the flue, and its corbelled brick shape traps more soot than most homeowners realize. We clean it on every sweep because a dirty smoke chamber restricts draft and pushes smoke back into the living room. This is standard in our sweep, not an add-on.

Styles & brands we work with
Chimney Cleaning
Chimney Cleaning means removing everything that does not belong inside the flue: creosote, soot, bird nests, leaves, and the occasional Houston squirrel stash. The work restores proper draft so smoke exits the house instead of rolling back into the room. Flint Chimney Co Houston does a full cleaning every time, from the firebox to the chimney cap, and we inspect the liner as part of the same visit. Expect $149 – $299 for a typical single-flue Houston home, with the final number written down and approved before we begin.
Flue Brush Sweeping
We use poly and steel rotary brushes sized to your exact flue dimensions, not a one-size-fits-all brush. The right brush removes deposits without scarring the liner, which matters for both clay tile and stainless systems. Every sweep ends with a visual and camera check to confirm the flue is clear.
Animal Nest and Debris Removal
Houston chimneys attract chimney swifts, squirrels, and raccoons, and a nest blocking the flue is a carbon monoxide risk the moment you light a fire. We remove nests and debris carefully, then recommend a proper cap so it does not happen again. If animals are present, we coordinate humane removal before cleaning.
Fireplace Cleaning
Fireplace Cleaning from our Chimney Sweep in Humble focuses on the firebox, hearth, and damper area where ash, soot, and small debris collect after every burn. The firebox is what you see, and it is also where air enters the combustion cycle, so a clean firebox means a cleaner, hotter, more efficient fire. We vacuum ash with HEPA-filtered equipment, scrub firebrick, clean the damper shelf, and leave the hearth wiped down. Fireplace cleaning is included in a standard sweep at $149 – $299, and we never leave ash dust on your furniture or floors.
Firebox and Hearth Care
We remove ash and soot from the firebox floor, walls, and the ash dump if your home has one. The hearth gets brushed and wiped, including the gap between the firebox and the hearth extension where debris hides. A clean firebox also makes it easier to spot cracks in the firebrick that need attention.
Damper Cleaning and Check
The damper is a steel or cast iron plate that opens and closes the flue, and it collects a surprising amount of soot on its top surface. We clean it and test the operation while we are there. A damper that does not fully close lets conditioned Houston air escape up the chimney all summer.
Chimney Services
Chimney Services is the umbrella term for everything we do beyond the basic sweep: inspections, repairs, caps, flashing, and liner work. Houston weather cycles between heavy humidity, Gulf storms, and occasional freezes, which puts real stress on masonry and metal components. Flint Chimney Co Houston provides these services with the same written-price rule and the same 365-Day Done Right Promise that covers our sweeps. Depending on what we find, we may recommend work from $300 to several thousand dollars, and nothing gets recommended without camera evidence you can see. When a repair falls under our guarantee, we return at no charge within the year.
Chimney Inspections
Every sweep includes a basic inspection, but we also offer dedicated Level 1 and Level 2 inspections for real estate transactions, storm damage, or post-fire checks. Our inspection includes a written report with photos from the camera run. If you are buying or selling a home in Houston, a Level 2 inspection is what most agents and insurers want to see.
Chimney Repairs and Relining
We repair crowns, repoint brick, replace flashing, and install stainless liners from DuraFlex when the existing flue is cracked or improperly sized. Flue relining, which is replacing the inner liner that channels smoke safely out of the house, is the single most common repair we recommend in older Houston homes. We also use HeatShield to resurface clay tile liners when full replacement is not necessary.
Chimney Sweep Certified
Chimney Sweep Certified means the technician at your door has passed industry training, carries identification, and works to a documented standard, not a guess. Flint Chimney Co Houston runs every technician through background checks and sends them in uniform so you know exactly who is walking in. We follow the Garrison Code, which is the same operating standard used by every Garrison Partners location across the region. A certified sweep in Houston costs the same $149 – $299 as our standard service, because certification is not an upsell for us.
What Certification Means on the Job
It means the tech knows how to size a brush, how to recognize a cracked flue tile, and how to spot clearance violations that a quick broom sweep would miss. It also means the work is done to a repeatable process, not whatever the tech feels like doing that day. The camera inspection at the end is our proof that the standard was met.
The Garrison Standard on Every Call
The Garrison Standard is our operating discipline: written price first, background-checked tech second, photographed work third, written guarantee fourth. No Houston chimney company in our family skips any of these steps. Hank Delano holds every tech at Flint Chimney Co Houston to this standard on every job, no exceptions.
Gas Fireplace Cleaning
Gas Fireplace Cleaning is different from wood fireplace cleaning because there is no creosote, but there is still soot, dust, and mineral buildup on logs, glass, and burners that reduces efficiency and can cause odors. Gas units still need the flue checked for blockages and the venting inspected for leaks, especially vent-free and direct-vent models common in Houston homes. We clean the glass, vacuum the burner area, inspect the log set, and check the venting path. Gas fireplace cleaning runs $129 – $199, which is less than a full wood chimney sweep because there is no creosote removal.
Log Set and Burner Cleaning
We remove the log set carefully, clean each piece, and vacuum the burner ports so the flame pattern returns to what the manufacturer intended. Sooty logs and a lazy yellow flame are signs the burner is clogged and burning inefficiently. We check for spider nests in the venturi tubes, which is a common Houston issue that causes delayed ignition.
Gas Venting Inspection
A gas fireplace produces carbon monoxide, and the venting is the only thing keeping it out of your living space. We check the vent run, termination cap, and any seals or gaskets for leaks. If you have a direct-vent unit, we verify the intake and exhaust are both clear and properly terminated.
Chimney Maintenance
Chimney Maintenance is the scheduled care that prevents the five-figure repair bill, and in Houston it matters more than in dryer climates because humidity accelerates masonry and metal deterioration. The core maintenance item is an annual sweep and inspection, which costs $149 – $299 and catches small problems before they become structural ones. We also recommend checking your chimney cap, flashing, and crown after any major storm, and resealing masonry when water absorption tests show it is time. A written maintenance plan from Flint Chimney Co Houston means you never have to remember when you last had it done.
Annual Sweep and Inspection
Once a year is the rule for any chimney that sees regular use, and the fall is the busiest season in Houston because everyone wants the first fire ready without worrying about what is in the flue. We document every visit with a camera report you keep. If you burn more than three cords a season, twice a year may be warranted.
Water Management and Masonry Sealing
Water is the enemy of any Houston chimney. We check the crown, cap, flashing, and brickwork for water entry points, and we apply ChimneySaver water repellent or a comparable product when the masonry is absorbing moisture. Sealing a chimney costs a few hundred dollars, while a rebuild from freeze-thaw damage costs thousands.
Brands We Service
We work with DuraFlex stainless steel liners more than any other brand because their flexibility and alloy quality handle Houston’s humidity and thermal cycling well. Our techs have installed and inspected hundreds of DuraFlex systems, and we stock their fittings and connectors for faster turnarounds on relining jobs.
HeatShield is our go-to for resurfacing clay tile liners that have minor cracking or spalling but are structurally sound. The cerfractory material bonds to the existing tile and restores a smooth, insulated flue path. We also regularly service and install components from Gelco and Olympia Chimney, including caps, dampers, and chase covers. Whether you have a DuraFlex, Gelco, Olympia Chimney, or HeatShield system, or any other make, we can service it.

AfterSigns You Need a Pro Right Now
- Smoke rolls back into the room instead of up the flue. That is a draft failure, and in Houston it is often caused by a blocked flue, a cold chimney, or negative air pressure in a tightly sealed house. It also means combustion gases are not exiting the way they should, and that is a carbon monoxide risk.
- You smell something like a campfire days after the last fire. That smell is creosote off-gassing, and it is strongest in humid weather because moisture activates the odor. Heavy creosote is the primary fuel source for chimney fires, and it needs mechanical removal, not a scented candle.
- There is a dark, flaky crust on the inside of the firebox or on the damper. That is creosote you can see, which means there is more you cannot see higher in the flue. Visible buildup in the firebox is a strong indicator that the chimney has not been swept in years.
- You hear animals, scratching, or chirping sounds from the chimney. Houston is home to chimney swifts, squirrels, and raccoons, and all of them will build nests in an uncapped flue. A nest blocks airflow and is a combustion hazard the first time you light a fire.
- Water stains appear on the ceiling or wall near the chimney after rain. That means the flashing, crown, or masonry is letting water in, and Houston storms expose those failures quickly. Water intrusion accelerates brick deterioration and can rot framing, and the fix is almost always cheaper if addressed early.
Our Process, Step by Step
- 1
Written estimate before any work. We arrive at the scheduled time, walk the job with you, and write down the exact price for the sweep and any additional work. You sign off before a single tool comes off the truck. The number on that paper is the number on the invoice.
- 2
Floor and hearth protection. We lay drop cloths from the entry door to the fireplace and cover the hearth and surrounding floor with protective sheeting. Our vacuums run HEPA filters so the fine ash does not enter your Houston home’s air.
- 3
Full system sweep. We brush the flue from top and bottom as needed, clean the smoke chamber, remove all debris from the firebox, and clean the damper. Every surface that touches smoke gets cleaned, not just the parts you can see.
- 4
Camera inspection with photo report. After the sweep, we run a camera through the flue and show you the images on the spot. You see the condition of the liner, the smoke chamber, and the cap. If we recommend a repair, you see the evidence yourself before you decide.
- 5
Cleanup and written guarantee. We remove all equipment, vacuum the work area, and leave the fireplace ready to use. If we performed any repair, you receive the 365-Day Done Right Promise in writing, valid for one full year, with a free return visit if a covered repair fails.
How Much Does Chimney Sweep Cost in Houston?
A standard chimney sweep in Houston runs $149 – $299 for a single-flue wood-burning fireplace. Gas fireplace cleaning runs $129 – $199. A Level 2 inspection, if needed for a real estate transaction or after a storm, adds $100 – $250 depending on the home. What moves the price: flue height, roof pitch and accessibility, severity of creosote buildup, whether animals or debris are present, and how many flues the home has. A two-story Houston home with a steep roof and a glazed creosote problem will land at the high end of the range. A single-story ranch with a well-maintained flue lands at the low end.
The way to avoid overpaying is simple: get the price in writing before work starts and make sure the camera inspection is included, not sold separately. Some companies quote a low sweep price and then add inspection, damper cleaning, and smoke chamber work as extras. Our sweep includes all of it. A free estimate from Flint Chimney Co Houston means we come out, look at the system, and give you a written number. No phone quote guesswork, no bait price.

Frequently Asked Questions About Chimney Sweep in Houston
A chimney sweep is the process of removing creosote, soot, and debris from the inside of your chimney flue, smoke chamber, damper, and firebox using brushes and vacuum equipment designed for the job.
