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.

AfterFast, Reliable Chimney Sweep Across Houston
If you own a home in Houston, your chimney almost certainly spends most of the year sitting idle in 80% humidity. That’s precisely what causes most of the problems we fix. A standard chimney sweep in Houston typically runs $189 – $289 before any repairs, and we can usually schedule you within a few days. Alcott Chimney Sweep has served Houston homeowners since 2002, and Ruben Castellano still insists on one thing above all: you know exactly who’s coming to your door, by name and photo, before the truck parks in your driveway. Call (336) 863-3889 for a free estimate.
Why Alcott Chimney Sweep Is Houston’s Preferred Chimney Sweep Company
Houston isn’t a city where you open the door to a stranger without thinking twice. We get that, because we’ve been serving this metro since 2002. Every technician who works in Houston passes a background check and identity verification under what we call the Threshold Standard. That’s not an optional upgrade. Before your appointment, you’ll receive the technician’s name and a photo. When they knock, they’ll hold up a photo ID badge. No exceptions, ever.
Our reputation in Houston was built the hard way: showing up on time, giving a written price before any work begins, and backing every repair with a written guarantee. If a repair fails within the coverage period, the second visit is free. That’s the 365-Day Done Right Promise, and it applies to every completed job in Houston. Ruben Castellano built Alcott around certainty, and that’s the opposite of what most Houston homeowners have experienced from chimney companies.
Chimney Services in Houston
Chimney Services in Houston rarely mean just running a brush up a flue. Here, the work typically starts with a Level 1 inspection, because a chimney dormant for nine or ten months in Gulf Coast humidity can hide crumbled mortar crowns, rust-perforated prefab fireboxes, or corroded dampers. A standard sweep plus Level 1 inspection in Houston runs $189 – $289. If you have a wood stove on a rural property outside the Loop, expect the higher end of that range because the creosote loading is typically heavier.
Sweeping and Creosote Removal
Creosote, the tar-like residue from wood smoke, accumulates much faster in air-starved, cooler chimney systems. If you burn green or unseasoned wood, that coating can harden into a glaze a brush can’t remove. In those cases, removal requires mechanical rotary tools or, in severe situations, removing the liner entirely. We’ll always show you the camera footage before recommending removal.
Level 1 and Level 2 Inspections
A Level 1 inspection is visual and includes everything accessible without moving walls or climbing a roof. A Level 2 inspection adds a camera scan of the flue interior, which matters in Houston because freeze-thaw cycles and humidity can cause damage you can’t see from the ground. The February 2021 freeze cracked plenty of clay flue tiles across the metro.

Chimney Sweep Certified in Houston
Chimney Sweep Certified in Houston means we follow the National Fire Protection Association’s NFPA 211 standard for chimney inspection and cleaning, and every technician is background-checked, identity-verified, and uniformed under the Threshold Standard. Soot removal, creosote removal, annual sweeps, and fireplace cleaning all fall under our certification. A standard creosote removal in Houston runs $189 – $329 depending on buildup severity and flue accessibility. You receive a written price before any work starts.
Annual Sweep Programs
For Houston homeowners who actually use their fireplaces during those cold fronts, we recommend an annual sweep before burn season starts in November. Even a handful of fires per year can deposit enough creosote to matter, especially if the chimney has drafting issues or you’re burning pine. We’ll set a reminder and call you back each fall, which is genuinely useful in a city where chimney maintenance tends to slip the memory.
Prefab and Factory-Built System Service
Most of Houston’s 1970s through 1990s suburban housing stock in Katy, Pearland, and Clear Lake contains factory-built zero-clearance metal fireplaces rather than true masonry chimneys. These systems rust from the inside out in Houston’s humidity. We service the steel fireboxes, dampers, and gaskets directly, and when replacement parts are needed we use brands like Olympia Chimney and Famco rather than generic substitutes.
Trusted Brands We Service in Houston
We install and service professional trade materials in Houston, not box-store substitutes. HeatShield resurfacing systems let us repair damaged flue liners without a full teardown when the structure allows. Gelco chimney caps and chase covers hold up to Houston’s relentless humidity far better than unpainted galvanized steel, and Famco supplies the dampers and vents we specify for prefab systems in Katy and Pearland. Because our Houston office keeps these components in local inventory, turnaround on repairs is faster, which matters when you’re trying to get your fireplace working before a cold front rolls in. We’ll always tell you the brand we’re installing and why it’s specified for your particular chimney system.
Common Chimney Sweep Problems We See in Houston Homes
- Third-degree creosote glaze from rural wood stoves. Out past Katy and throughout Waller County, wood stoves are primary heat sources. Homeowners burning green oak or unseasoned pine build glazed creosote faster than a brush can remove it. By the time we’re called, the liner often has to come out.
- Chimney swift nesting in uncapped flues. Between April and October, federally protected chimney swifts nest in uncapped Houston chimneys along the Texas Gulf Coast flyway. If active eggs or chicks are present, cleaning is a federal offense under the Migratory Bird Treaty Act. We schedule accordingly.
- Humidity-rotted prefab fireboxes. In Houston’s 75 – 90% relative humidity, a steel firebox that looks fine in October can show rust perforation in a March inspection. Corroded dampers and degraded gaskets are the most common findings.
- Freeze-cracked clay flue tiles. Winter Storm Uri in February 2021 subjected chimneys across Houston to sustained sub-20°F temperatures they were never engineered for. We’re still finding cracked flue tiles and spalled mortar crowns from that week.

FAQs About Chimney Sweep in Houston
Because the federally protected chimney swift nests inside uncapped flues from roughly April through October across the Texas Gulf Coast flyway. If active eggs or chicks are present, federal law prohibits disturbing the flue, even for cleaning. So the safe window collapses: pre-April inspections or post-departure fall cleanings only. If you call us in July, we’ll schedule a capped-chimney check and outdoor inspection now, but the full sweep waits until the swifts have left. Call (336) 863-3889 and we’ll put you on the right calendar.
Every 30 to 60 days of active burning, which for a rural Houston wood stove used as primary heat means two to three sweeps per burn season. Rural stoves burning green or unseasoned local wood load creosote far faster than city fireplaces used occasionally. We drove out past Katy to a rural property where a homeowner’s flue was glazed with third-degree creosote our brush couldn’t touch. We removed the glazed section, relined the flue with DuraFlex components, and used HeatShield to repair the spalling crown. Shorter sweeping intervals are the only reliable defense.
A Level 1 is a visual check of all accessible parts, done during a routine sweep. A Level 2 adds a closed-circuit camera scan of the entire flue interior and is what we recommend after any real estate transaction, after the 2021 freeze, or after years of skipped maintenance. A Level 3 is the most invasive, involving partial removal of chimney structure to access hidden areas, and is what we recommend only when a Level 2 reveals damage that could compromise safety. In Houston, we push Level 2 more than most markets because humidity hides damage.
Factory-built zero-clearance metal fireplaces that dominate 1970s through 1990s suburban Houston are steel structures sitting in 75 – 90% relative humidity for most of the year. That moisture rots the firebox from the inside out. By the time you call us, the damper is often rust-frozen, the gaskets are decomposed, and the firebox shows perforation. We use Famco and Olympia Chimney components for replacement where possible, but sometimes the entire unit is beyond safe repair. Ask for a Level 2 inspection if you haven’t had one in years.
Burn only seasoned hardwood at or below 20% moisture content, keep the stove hot enough for secondary combustion, and never burn pine, green oak, or construction scraps. In Houston’s humid climate, “seasoned” means split and stacked under cover for at least 9 to 12 months. Unseasoned wood cools the flue and condenses tar-like creosote faster than you’d think possible. A magnetic stove thermometer helps you see whether you’re burning hot enough. Call (336) 863-3889 for a free estimate and we’ll go over your burning setup on site.
