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.

We schedule most San Leon work within three to five business days, not a two-week window.

Salt air off Galveston Bay does more damage to chimneys than fire does in this town. We see it on nearly every bayside inspection. That reality shapes how we approach a Chimney Sweep in San Leon: it isn’t just brushing soot, it’s checking the cap, the damper, the crown, and the flashing for corrosion that a standard brush-and-go would miss entirely. That’s why every sweep we perform here includes a camera inspection and a photo report you can hold onto. No guesswork, no “trust me on this.”
Why Flint Chimney Sweep Is San Leon’s Preferred Chimney Sweep Company
San Leon homeowners have been calling Flint Chimney Sweep for a simple reason: we put the price in writing before any work starts, and we stand behind repairs with a 365-day Done Right Promise. That’s a written guarantee, valid for one full year. If a covered repair fails inside that window, we come back at no charge. No argument, no invoice, no fine print. That’s the Garrison Standard, and Hank Delano runs our work by it every single day.
Our background-checked, uniformed technicians show up inside the window we give you. You know exactly who’s walking through the door. The phone line at (830) 251-4560 is answered by a live person around the clock. No voicemail tree, no callback form. That matters when you smell something odd in the living room on a damp bay night and want a straight answer at nine p.m.
We dispatch crews into San Leon from our scheduling office in the Dallas-Fort Worth metro, but the technicians who show up know Galveston Bay conditions firsthand. They know what bay humidity does to a damper assembly in two seasons versus ten inland. They check for what this specific town’s air does to metal and mortar. That local read is the difference between getting a sweep and getting the chimney actually looked at.
Chimney Sweep Certified in San Leon
When we say Chimney Sweep Certified, we mean a sweep that meets the NFPA 211 standard as a baseline and goes a step further in San Leon: after the flue is brushed and the firebox cleaned, we run a camera the full length of the liner and hand you a photo report showing what was in there and what it looks like now. A standard sweep in San Leon runs $175 to $325. You get that number in writing before we book, so there’s no surprise when we arrive.
Creosote is the flammable residue smoke leaves behind. In a salt-humid environment like Galveston Bay, creosote absorbs moisture differently. It gets sticky first, then dries into a glazed, tar-like coating that a brush alone won’t remove. Second-degree glazing hides inside a liner even when the surface looks clean. We don’t assume anything; the camera tells us exactly what’s on the liner wall.
Creosote and Soot Removal
GLAZED creosote from a few years of bay-humidity cycling needs mechanical removal, not just a wire brush. We handle that with professional rotary tools matched to the liner material. We tell you honestly how much buildup is there, what we can remove, and whether anything can safely wait until next season.
Annual Sweep Before Burning Season
Even if you never light a fire, NFPA 211 says inspect the chimney every year. Salt air corrodes the cap and damper no matter what. A sweep before October catches that damage before it leaks water into the smoke chamber. Most San Leon customers book an annual sweep in September, and we’re ready for it.
Gas Fireplace Cleaning in San Leon
Gas Fireplace Cleaning in San Leon homes is a different job than wood flue sweeping, and it matters more than people assume. Gas fireplaces still produce soot, still draw moisture into the vent system, and still let salt-laden air settle on log sets, burners, and vent caps. A cleaning runs $150 to $275 depending on whether it’s direct-vent or vent-free, and we give you the exact number in writing before we schedule.
What we do: remove and clean the log set, brush the vent, check the burner for clogs and corrosion, and inspect the vent termination outside for rust. Galveston Bay salt spray shortcuts the life of exposed metal components. We see gas fireplace vent caps on bayside homes rusted through in five years. A cleaning catches that before water finds its way down the vent chase.
Burner and Log Set Care
Dust and salt haze settle on gas logs and reduce flame quality. We clean the logs with proper materials, not household cleaners that leave residue. The burner gets a full inspection for clogged ports and flame pattern. If it’s not burning evenly, we tell you and we quote the repair before doing anything.
Vent and Cap Inspection
The cap on a gas vent is the same story as any chimney cap in San Leon: it rusts. We check the vent run for obstruction and moisture intrusion. If the cap is failing, you’ll know what a replacement costs before we order anything. Most replacements run $85 to $195 in this market, and we use stainless hardware that outlasts galvanized.
Trusted Brands We Service in San Leon
We work with a focused list of brands because we’ve seen them hold up in coastal air and because we can get parts fast when a San Leon repair comes up. For liner work we use HeatShield, the ceramic coating we apply to repair flue cracks without a full re-line. We install Olympia Chimney caps and dampers, and we stock Famco and Gelco components for replacements. If we need a part we don’t carry on the truck, it’s usually in hand within three to five days. You get the brand name on the written quote, so you know exactly what you’re paying for.
Common Chimney Sweep Problems We See in San Leon Homes
- Rusted-out dampers and caps on bayside homes. The salt-laden airflow off Galveston Bay corrodes metal far faster than inland Texas. We regularly pull dampers that have rusted through on chimneys that haven’t burned a fire in years.
- Fluffy, salt-dampened first-degree creosote in unused flues. Bay moisture soaks into creosote and makes it sticky first, then it sits there for years. It may not be glazed, but it still needs to come out before it becomes a second-degree problem.
- Spalled chimney crowns from humidity cycling. The constant wet-dry cycling along the coast cracks concrete crowns early. Water gets in, freezes rarely but wets constantly, and the crown crumbles. Homeowners who never light a fire never notice until the ceiling stains.
- Second-degree creosote glaze hiding inside liners. We’ve swept chimneys in San Leon where the brush came out clean but the camera showed glazed buildup on the liner wall. A brush won’t take that off. It takes mechanical removal, and missing it means the chimney is not actually clean.

FAQs About Chimney Sweep in San Leon
Yes, and it has nothing to do with fire. San Leon’s salt-humid air off Galveston Bay corrodes damper hardware, caps, and flashing whether the chimney is used or not. NFPA 211 requires an annual inspection regardless of use. We were called to a home on Bayshore Drive where the owner had never burned a fire but had a musty smell in the living room. The damper pulled out rusted, the flue liner had fluffy first-degree creosote from years of humidity, and the cap had rotted to the point it was letting bay moisture straight into the smoke chamber. We swept it, replaced the cap, applied HeatShield to a hairline crack, and gave the homeowner a photo report. No fire ever burned, but the situation was real. Call (830) 251-4560 for a written quote.
Once a year at minimum. If you burn wood regularly through San Leon’s short but real burning season, twice a year is not too cautious. The relevant variable is creosote accumulation, and coastal humidity accelerates the progression from first-degree to second-degree. The brush is important. The camera inspection is what tells you whether the flue is actually clean. If the camera shows glazed creosote after a brush, we’ll tell you plainly and quote the mechanical removal. No upsell games.
In San Leon, the camera finds glazed creosote layered inside the liner that a brush passes right over. It finds hairline cracks in the smoke chamber and liner that are invisible from below. It finds rusted damper tracks and failed cap screens that a visual check from the ground misses. The camera report we hand you documents all of it. We don’t recommend a repair unless the camera shows it, and you see the image with your own eyes before you approve anything.
Yes. The corrosive influence of Galveston Bay air doesn’t stop at the waterfront. Bayside homes on Bayshore Drive get it heaviest, but the prevailing salt-laden airflow reaches a few blocks inland along San Leon’s flat grade. We see rusted dampers and crowns well north of the waterfront. Humidity and salt travel together here. Anything metal on the exterior of the chimney is on a timeline. A stainless cap and a proper crown seal are the defense, and they’re too cheap to skip. We’ll show you what’s failing before we quote it.
Gas fireplaces need cleaning annually too, even when the glass looks fine. Soot settles on the logs and burner ports in any gas appliance. Bay moisture accelerates corrosion on the vent cap and burner assembly, and a clogged or rusted burner can produce carbon monoxide in the living space. That’s not scare talk, it’s the reason gas fireplaces have oxygen-depletion sensors and the reason we inspect the vent run end to end. A cleaning runs $150 to $275 in San Leon, and we’ll give you the exact number before we schedule.
