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 Decatur
Most gas fireplace repairs in Decatur run between $175 and $540, and a technician can usually diagnose the problem the same day you call. The older bungalows around Oakhurst, Winnona Park, and College Heights bring a specific set of venting problems that newer suburbs rarely see, so we approach every job by looking at how the fireplace connects to the chimney, not just the burner itself. If your gas logs are sooting the glass, snuffing out after lighting, or you smell something damp near the firebox, call (336) 863-3889 and Ruben Castellano’s team will walk you through what likely went wrong before we ever send a truck.
Why Alcott Chimney Sweep Is Decatur’s Preferred Gas Fireplace Repair Company
Decatur homeowners call us because gas fireplace work here is rarely simple. A vented log set in a 1930s firebox was often shoved into a flue that was built for wood smoke, not gas combustion. That means the repair has to account for the chimney, the cap, the liner, and the damper, not just a bad thermocouple. We have spent years working on the original unlined and clay-tile flues that run through this city’s Craftsman bungalows and Tudor cottages, so the diagnosis usually points to the stack, not the valve.
Every technician we send is background-checked and identity-verified through the Threshold Standard, which means you will know the technician’s name, see their photo, and check their ID badge at the door before you let anyone in. Alcott Chimney Sweep has been part of the Threshold Group family of home-service companies since 2002, and the 365-Day Done Right Promise applies to every repair we complete in Decatur. If something fails, the second visit is free.
Our Gas Fireplace Repair Services in Decatur
Gas Fireplace and Vented Log Set Inspection
We start by watching the flame and checking the gas pressure before we ever open up the chimney. In Decatur, vented log sets from the 1980s through the early 2000s are common, and many of them are oversized for the firebox they sit in. That mismatch is the root cause of most rolling flames, sooting glass, and back-puffing we see between Clairemont Avenue and South Candler Street.
Level 2 Camera Inspection With Homeowner-Visible Footage
If your fireplace has been acting up, we will run a camera through the flue and show you the footage on a tablet while we are standing in the same room. Nothing gets recommended without you seeing the evidence yourself. That matters in Decatur because the age of the housing stock means there is often something hiding behind a wall or above a smoke chamber that no amount of surface inspection would catch.
Gas Flue Relining to Current Code
When a house predates modern gas venting codes, the original flue is often unlined or has terracotta tiles that have spalled and offset over 70 or 80 years. We install DuraFlex liner systems sized to whichever gas appliance you are running. A liner that is too big lets combustion gases cool too fast and stall; too small restricts draft. Either way, the gases spill back into the house. After a reline, the fireplace drafts the way the manufacturer intended.
Chimney Cap Replacement and Animal Removal
Decatur’s tree canopy is a beautiful problem. Caps in Oakhurst and Winnona Park fill with leaves, twigs, and squirrel nests faster than anywhere else we work. We remove whatever is blocking the flue, repair or replace the cap, and make sure the termination is secure. If an animal has chewed through a liner seam or dragged debris into the smoke chamber, we address that before the gas appliance is fired again.

Common Gas Fireplace Repair Problems We See in Decatur Homes
- Vented gas logs in an unlined or spalled clay-tile flue: The original firebox was built for occasional open-wood fires, not a gas appliance running for hours at a time. The stack runs hotter and wetter than it can draft, so combustion gases spill back into the room. You will notice soot stains on the mantle or a stale, gassy smell that lingers after the fire is off.
- Chimney caps packed with canopy debris: Oakhurst and Winnona Park sit under a dense hardwood overstory, and caps there fill with leaves and twigs fast. Blocked draft means the gas logs will not stay lit, or the burner flames roll lazily instead of burning clean. Animals nesting inside uncapped flues is a standard finding in Decatur, not an occasional one.
- Crumbling mortar around the gas flue termination: Decatur’s humid summers soak the older, softer brick common in intown homes, and hard winter freezes expand the trapped water. Crowns and mortar joints spall until the flue termination loosens. You may not notice until dampness or a faint smoky smell shows up at the fireplace long after the last rain.
- Incorrect damper settings after a gas conversion: A damper that was never altered when wood became gas stays fully closed or partially open. Either way, the draft is wrong. Our gas fireplace repair team corrects the damper so the burner lights with a steady, drafted flame instead of back-puffing into the room.

FAQs – Gas Fireplace Repair in Decatur
My Decatur bungalow has a gas log set in the original 1930s firebox – does it need a liner?
Almost certainly yes. Decatur’s 1920s and 1930s homes were built with fireboxes and flues sized for wood, not gas, and most of those flues were never lined or have terracotta tiles that have spalled and shifted. A gas appliance vents hotter, wetter exhaust into a stack that cannot safely move it, so combustion gases stall and spill back. We will camera-inspect the flue and show you exactly what is there before recommending a reline. Call (336) 863-3889 to book an inspection.
Why is my gas fireplace flame rolling and sooting the glass in my Winnona Park home?
Flame rolling and sooting almost always mean the flue is not drafting properly. In Winnona Park specifically, the dense tree canopy dumps leaves and twigs into caps within weeks, and animal nesting inside the flue is common. A blocked or partially offset clay-tile flue will not move exhaust fast enough, so the flame rolls and carbon builds up on the glass. We start with a camera inspection to find exactly where the blockage is.
Do you really need to camera-inspect a gas fireplace, or is that an upsell?
You need to see the evidence before any repair is recommended, and a camera is the only way to get it. Alcott Chimney Sweep does not ask you to trust a verbal diagnosis of a chimney you cannot see inside. We run the camera, show you the footage on a tablet, and explain exactly what it means. If the flue is clean and sound, we say so and charge for the inspection only. Nothing is recommended without homeowner-visible footage, ever.
We just bought a 1940s Oakhurst house and the fireplace was sealed off for decades. What’s involved?
First, we check that the chimney is structurally sound and the flue is clear. In Oakhurst, sealed fireplaces from that era often have collapsed or offset terracotta tiles, significant mortar erosion, and decades of accumulated debris. We run a Level 2 camera inspection, and from there we will tell you whether the flue can be used as-is or needs a DuraFlex reline before any gas appliance is connected. You get a written quote before work starts, and the inspection footage is yours to see.
What actually causes the mortar on my chimney crown to crumble so fast here?
Decatur’s humid subtropical climate saturates the older, softer brick common in intown homes through the hot, wet summers, and hard winter freezes expand the trapped water. The constant dampness under the tree canopy in Oakhurst, Winnona Park, and College Heights means crowns seldom fully dry out, so the mortar erodes years faster than on open-lot homes just outside the city limits. We repair or rebuild crowns and reset the flue termination so the gas venting system stays sealed and drafts correctly.
