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.
Fast, Reliable Gas Fireplace Repair Across Lehigh Acres
Gas fireplace repair in Lehigh Acres usually costs $185 – $310 for common fixes like thermocouple or thermopile replacement, while a flue reline for a gas appliance runs $2,400 – $4,800 depending on the stack height and liner material. Most calls we take from Lehigh Acres homeowners are diagnosed within one visit, often the same week you call. The honest truth in this part of Lee County: a lot of what gets called “gas fireplace repair” is actually a venting problem caused by a 1970s clay-tile flue that was never sized for a gas log set. Our team at Alcott Chimney Sweep works these issues every week in Lehigh Acres, and we put a camera up every flue before we quote a single dollar. Call (336) 863-3889 if your fireplace smells, back-drafts, or won’t hold a pilot.
Why Alcott Chimney Sweep Is Lehigh Acres’s Preferred Gas Fireplace Repair Company
We’ve been doing gas fireplace and venting work since 2002 through the Threshold Group family of home-service companies, and the calls from Lehigh Acres have a shape to them. Older CBS tract homes, decorative fireplaces that sat dark for twenty years, then a vented gas log set dropped into a flue that was never designed for it. That’s the Lehigh Acres pattern, and it’s one our techs can recite from memory. Ruben Castellano, who leads our repair operations, built the process around one rule: nobody tells a Lehigh Acres homeowner they need a replacement or reline until that homeowner has seen the camera footage with their own eyes.
Every technician who comes to your door has passed a background check and identity verification under the Threshold Standard. That’s not a premium option. It’s the baseline for every visit. Before we arrive, you’ll know the technician’s name and see their photo. They show ID at the door, uniformed and clearly badged. For homeowners who are often home alone, parents with kids, and older residents across Lehigh Acres villages, that matters as much as the repair itself.
Every repair carries a written guarantee, included at no extra charge. If the repair fails within the coverage year, we come back free. That’s the 365-Day Done Right Promise, and it’s on paper every single time. No vague assurances. No punch list surprises.
Our Gas Fireplace Repair Services in Lehigh Acres
Camera-First Gas Fireplace & Vented Log Set Inspection
Before we touch a burner or valve in Lehigh Acres, we run a Level 2 inspection with a camera through the flue. You see the footage live. We’re checking liner integrity, the smoke chamber, the crown, the cap, and the way the gas appliance drafts inside the original stack. In Lehigh Acres, this step catches the hidden problems that caused the symptom you called about.

Flue Liner Relining for Gas Appliances in Original Clay-Tile Stacks
This is the single most common structural correction we perform in Lehigh Acres. A 1970s or 1980s home was built with a clay-tile flue sized for a wood fire. A gas log set vents cooler, smaller-volume exhaust into that oversized flue, and in Southwest Florida humidity it stalls. We reline with professional trade materials like HeatShield or a properly sized stainless system, restoring draft and stopping back-draft and odor at the source. We install only trade-grade brands: HeatShield, DuraFlex, Olympia Chimney, Famco, Copperfield. No box-store substitutes.

Pilot, Thermocouple, Thermopile, and Burner Diagnosis
When a Lehigh Acres gas fireplace won’t hold a pilot or won’t light clean, we test the venting first, then the component path. If the flue is fine, we replace the failed part. But we won’t swap parts blindly. If a sticky valve is really rain intrusion from a cocked cap off Homestead Road, the valve replacement alone won’t fix the actual problem. We show you the evidence before any part goes in.

Chimney Cap, Crown, and Damper Repair for Gas-Converted Fireplaces
Hurricane Ian took caps and cracked crowns across Lehigh Acres in September 2022, and many of those fireplaces have gone two-plus years with open flues in 75 – 80% humidity. We replace caps, repair crowns, and assess damper condition as part of any gas repair, because a gas log set under a missing cap is collecting subtropical rain whether you light it or not.

Trusted Brands We Service in Lehigh Acres
We service and install products from the brands chimney professionals actually specify: HeatShield, DuraFlex, Olympia Chimney, Famco, and Copperfield. Because we carry these trade lines directly, we’re not waiting on regional distributors to route parts into Lehigh Acres. That shortens turnaround when a liner system or cap assembly needs to be matched to your existing stack. If we’re at your home near Lee Boulevard and the flue needs a component, we can usually schedule the fix faster than a company that has to source after diagnosis.
Common Gas Fireplace Repair Problems We See in Lehigh Acres Homes
- Gas log set back-drafting through a wood-sized clay-tile flue: The 1970s – 1990s CBS tract homes around Greenbriar and Joel Boulevard were built with wood-burning fireplaces that almost nobody used. A gas log set was dropped in later, vented into a flue sized for a wood fire. The gas exhaust cools, stalls, and pushes back into the room, especially during humid weather.
- Pilot won’t hold through the wet season: June through October puts 75 – 80% relative humidity and daily rain into any flue with a missing or cocked post-Ian cap. Firebox moisture reads as a valve problem, but the camera shows water staining and corroded burner components from the open flue above.
- Cracked crowns and missing caps from Hurricane Ian: In Lehigh Acres, Ian’s Category 4 winds tore flashing, shifted caps, and spider-cracked crowns. The firebox can look spotless, the flue coated in black organic growth, and the pilot can’t stay lit. That combination is a venting failure, not a bad thermocouple.
- Decorative firebox that looks clean, flue that’s actually failing: A fireplace that was never burned hides its problems well. Spalled mortar joints and a flue liner cracking from moisture look invisible from the living room. A camera inspection shows what’s above the damper, and that’s the only way to know if a gas appliance is safe to operate in that stack.

FAQs – Gas Fireplace Repair in Lehigh Acres
Usually the chimney. In Lehigh Acres, the summer pattern of a pilot that won’t hold is most often caused by a clay-tile flue sized for wood, now venting a gas log set that stalls in 75 – 80% humidity. The burner components may test fine while the flue above can’t pull a draft. We run a camera before we say any more. Call (336) 863-3889 and we’ll show you exactly what’s happening inside your flue.
Yes, because an uncapped flue in Lehigh Acres has been collecting subtropical rain for two-plus years, whether you light the fireplace or not. If a gas log set is installed in that firebox, the burner, valve, and damper have been sitting in moisture, and the flue liner has been degrading quietly. The firebox can look clean while the liner above carries mold and spalled mortar. An inspection finds the problem before the first flame of the season. Call (336) 863-3889 to schedule one.
You’ll see it on camera. That’s the standard we hold for every Lehigh Acres job. Nothing is recommended without footage you can watch yourself: the cracked liner, the water staining, the cocked cap, the draft test results. If the camera doesn’t show a problem, we don’t quote a repair. You don’t take anyone’s word for it, including ours. Call (336) 863-3889 and we’ll walk you through the inspection.
A gas log set in a clay-tile flue that’s oversized for the appliance can cool exhaust so fast that combustion byproducts condense on the tile walls. Add Southwest Florida humidity and a missing post-Ian cap, and that film becomes black organic growth. The firebox stays clean because the problem is in the flue, not the firebox. The fix is usually a properly sized reline, not a burner replacement. Call (336) 863-3889 for a camera inspection and an honest quote.
Sometimes, but only after the flue is inspected and passes. A gas log set venting into a cracked or deteriorating clay-tile flue isn’t safe, and a repair to the burner won’t address that. If the liner is intact and sized correctly, the appliance can be serviced in place. If it isn’t, we’ll show you the camera footage and recommend the reline work needed before we stand behind any repair. Call (336) 863-3889 and we’ll give you a straight answer based on what the camera shows.
If your gas fireplace is back-drafting, smelling, or won’t hold a pilot in Lehigh Acres, don’t assume the burner is the problem. Most of what we see comes from above the firebox: Ian-stressed crowns, missing caps, and flues that were never sized for a gas appliance. We’ll show you the evidence before we quote anything, and every repair comes with the 365-Day Done Right Promise and a written price before work starts. Call (336) 863-3889 for a free estimate.
