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 Gas Fireplace Repair Across Highland Village
Gas fireplace repair in Highland Village typically costs between $150 and $650 depending on whether you’re looking at a thermocouple replacement, a seized damper, or a full vent-collar repair on a zero-clearance unit. Most repair jobs here are completed in a single visit, and Alcott Chimney Sweep has been serving homeowners since 2002. We know the lake-adjacent neighborhoods, the prefab fireplace stock, and the specific ways North Texas humidity attacks gas log assemblies. If your burner won’t stay lit or you smell gas near the firebox, call (336) 863-3889 and a live person will answer, day or night.
Highland Village sits right on the northern shore of Lake Lewisville, and that location creates a repair pattern we don’t see in the inland DFW suburbs. Morning fog rolls into the low-lying cul-de-sacs of Heron’s Cove and Wildridge, and it keeps chase covers, dampers, and vent collars damp for hours after sunrise. For gas fireplaces that only get used a handful of times each winter, that persistent moisture does quiet damage all year long. We built this page to explain exactly what that looks like, what it costs to fix, and why we never recommend a repair without showing you the camera footage first.
Why Alcott Chimney Sweep Is Highland Village’s Preferred Gas Fireplace Repair Company
Ruben Castellano runs Alcott Chimney Sweep with a straightforward rule: every customer gets a written price before any work starts. No estimates that grow at the end of the job. No “while we were in there” add-ons. In Highland Village, where most fireplaces are factory-built units from the 1980s through the 2000s, that matters because the wrong diagnosis is expensive. A tech who doesn’t know zero-clearance units will tell you the whole fireplace needs replacing when the real problem is a $40 thermocouple or a rusted damper clamp.
We also do something no other Gas Fireplace Repair company in the area does: before the technician arrives, you get their name and photo sent to you directly. They show a photo ID badge at the door. Every time. If you’re home alone, or you’ve got young kids, or you’re an older homeowner who wants to know exactly who’s crossing the threshold, that’s not a perk. It’s the Threshold Standard, and it’s been in place since Alcott joined the Threshold Group family of home-service companies. Ruben’s crews are background-checked and identity-verified before they ever step onto a property in Highland Village.
Key Takeaways:
- Gas fireplace repair in Highland Village runs $150 – $650 for most common fixes.
- Lake fog in Heron’s Cove and Wildridge accelerates damper rust and vent-collar corrosion.
- You’ll see camera evidence of any recommended repair before you approve the work.
- Every repair carries a written guarantee with a free return visit if it fails.
Our Gas Fireplace Repair Services in Highland Village
Gas Log Set and Burner Assembly Inspection
Highland Village homes almost exclusively use factory-built zero-clearance fireplaces, and the gas log assemblies inside them have brand-specific clearance and BTU ratings. A generic technician might miss that the log set installed in your 1990s unit was never rated for that firebox, which leads to incomplete combustion, sooting on the glass, and carbon monoxide risk. We inspect the burner pan, the gas valve, the pilot assembly, and the log placement against the manufacturer’s specs, then show you what we found.
Level 2 Camera Inspection of the Flue Liner and Vent Collar
This is the service that catches what lake humidity does to prefab stacks. We run a camera up through the flue liner and the vent collar, and you watch the footage with us. In Highland Village, we regularly find vent collars rusted from condensation, first-degree creosote glazing inside what should be a clean metal flue, and damper assemblies so corroded they won’t seal. If we recommend a repair, you’ll see exactly why on the screen before you spend a dollar.
Damper and Venting Repair on Zero-Clearance Fireplaces
The fog pattern in the lake-adjacent sections of Highland Village attacks dampers faster than almost anywhere else in Denton County. A rust-seized damper on a gas fireplace is dangerous because it changes the draft characteristics of the entire unit: combustion air leaks out, exhaust doesn’t vent properly, and the flame can cut out or back-draft. We replace damper assemblies, clean and seal vent collars, and repair chase covers on low-slope prefab stacks throughout Highland Village’s 75077 and 75022 ZIP codes.

Trusted Brands We Service in Highland Village
We stock and install parts from the brands chimney professionals actually specify. That includes DuraFlex liner systems, Olympia Chimney venting components, and Copperfield chase covers and accessories. When your gas fireplace in Highland Village needs a replacement damper assembly or a new vent collar, we’re not pulling a generic part off a big-box shelf and hoping it fits. We use the same materials the original manufacturer rated for your unit, and because we keep common parts on hand for the zero-clearance models that dominate Highland Village’s 1980s – 2000s housing stock, most repairs don’t require a second visit.
Common Gas Fireplace Repair Problems We See in Highland Village Homes
- Rust-seized dampers in Heron’s Cove and Wildridge: Morning lake fog settles into these low-lying sections and keeps damper assemblies damp for hours after sunrise, even in fireplaces used three or four times a year. The damper seizes open, the draft pulls cold air down the flue, and the burner cuts out mid-cycle.
- Mismatched liner ratings on converted 1980s fireplaces: Many older custom homes in Highland Village originally had wood-burning fireplaces with clay-tile flues, then got converted to gas log sets without installing a properly sized liner. The exhaust cools too fast on the oversized flue wall and back-drafts into the living space.
- Condensation on roof-level chase caps: The low-slope prefab stacks common throughout the city bead water on their chase caps when lake humidity is high, and that moisture drips down onto the gas valve assembly. The oxygen-depletion sensor shorts, and the fireplace won’t light or won’t stay lit.
- Expansive clay soil cracking crown slabs: Denton County’s clay soils swell in wet years and contract in drought, which shifts zero-clearance chases just enough to open flashing seams. Water reaches the firebox floor, rusts the burner pan, and you smell rust and old gas every time the unit fires.

FAQs – Gas Fireplace Repair in Highland Village
My gas fireplace in Highland Village only gets used a few times each winter – do I really need a Level 2 inspection?
Yes, and here’s the Highland Village-specific reason: infrequent use combined with lake humidity creates a pattern where dampers rust open and vent collars corrode while the fireplace sits idle for months at a time. A Level 2 camera inspection catches that moisture damage before a cold snap arrives and you discover the unit won’t stay lit. For gas fireplaces in Heron’s Cove, Wildridge, and other lake-adjacent sections, we recommend a camera pass every year even if you only burn on the coldest nights. Call (336) 863-3889 to schedule one.
Why did my gas log set start cutting out after a few minutes when it never did before?
In Highland Village, the most common cause is a rust-seized damper that’s stuck open. When the damper won’t seal, cold air drafts down the flue and disrupts the combustion-air balance, so the flame lights, burns for a minute or two, and then the thermocouple cools and cuts the gas. We also see this from corroded vent collars and from oxygen-depletion sensors that have shorted after condensation dripped down from the chase cap. A camera inspection shows which one it is, usually in under an hour.
Can you service my DuraFlex or Olympia Chimney liner if it was installed by a different company?
Yes. We service and repair gas fireplace liners from DuraFlex, Olympia Chimney, Famco, and Copperfield regardless of who did the original installation. What matters is the condition of the liner and whether it’s the correct rating for your unit. In Highland Village, we frequently find liners that were never matched to the fireplace’s BTU output, and that’s a safety issue no matter who installed it. Bring us the brand and model if you know it, and we’ll inspect it on camera.
What does lake humidity actually do to a prefab fireplace in Highland Village?
The fog that settles over the neighborhoods nearest Lake Lewisville keeps metal components damp for hours after sunrise, and that speeds up rust on the damper assembly, the vent collar, and the chase cover. You’ll see white powdery efflorescence on the chase exterior, and inside the firebox the damper will feel stiff or stuck. Over time, condensation drips down onto the gas valve and the oxygen-depletion sensor, which causes intermittent ignition failures. This is why a fireplace that’s barely used can still need repair work in Highland Village.
Do you recommend work on my gas fireplace without showing me what’s wrong first?
No. This is the reason we exist. Highland Village is an affluent market, and we know homeowners here get pitched liner replacements and full fireplace rebuilds they can’t verify. Our rule is simple: if we recommend a repair, we show you the camera footage. You see the rusted damper, the corroded vent collar, the cracked chase cover, whatever it is. If the fireplace can safely wait, we tell you that too and put it in writing. No repair begins without your approval of a written price, and every repair carries a written guarantee. If it fails, the second visit is free.
