Fast, Reliable Gas Fireplace Repair Across Marietta
A gas fireplace that won’t ignite, soots up the glass, or smells odd when it rains isn’t just an annoyance in Marietta. It’s usually a venting or moisture problem tied to how homes here were built, and it can flag a carbon monoxide risk. We’re Hadley Chimney Marietta, and our Gas Fireplace Repair team diagnoses these issues down to the exact flue, burner, or firebox failure before we ever quote a repair. Call (762) 249-4619 for a written, photo-documented estimate.
Why Hadley Chimney Marietta Is Marietta’s Preferred Gas Fireplace Repair Company
Marietta’s housing stock spans 1920s Craftsman bungalows near the Square and 1980s subdivisions in East Cobb, and those two homes often show the same symptom for completely different reasons. Our techs know which questions to ask first – What year was the house built? Is the flue original masonry or prefab metal? When did the glass last get cleaned? – because the answer changes where we look. We’re not a general handyman service. We’re a chimney-only company serving Gas Fireplace Repair in Marietta with techs who spend every day working on flues, fireboxes, liners, and venting systems specific to Cobb County homes.
Every visit starts with a written price before work begins. No verbal estimates that drift upward once the tech is in the attic. You get a camera scan of your flue interior, photos of the problem, and a flat quote for the exact repair. If we fix it and it fails within 365 days, we come back free under our 365-Day Done Right Promise. That’s a written guarantee on every our Chimney Repair in Marietta, not a promotional gimmick.
You’ll also get live arrival tracking, a uniformed and background-checked technician by name, and a digital invoice you can pay from your phone. That’s the Relay Visibility Guarantee, and it applies to every job we book in Marietta, from a simple thermocouple replacement to a full firebox rebuild.

Our Gas Fireplace Repair Services in Marietta
Flue Liner Inspection and Replacement
Older Marietta homes with original masonry chimneys often have clay-tile flue liners that have cracked after decades of freeze-thaw cycles. A cracked liner on a gas fireplace does two things: it lets moisture into the chimney chase and it allows exhaust gases, including carbon monoxide, to seep back into living space. We inspect with a camera, show you the footage, and if replacement is needed, we install a properly sized liner, often a Marietta Duraflex service system, matched to your specific gas appliance. A gas insert inside an original 1920s or 1940s chimney almost always needs a liner to perform correctly.
Chimney Cap and Crown Repair
Uncapped flues are a recurring problem in Marietta’s heavily treed neighborhoods off Whitlock Avenue and Dallas Highway. Pine needles, oak leaves, and squirrel nests block gas fireplace exhaust and force carbon monoxide back into the house. A cracked or spalling chimney crown lets rainwater run into the chase, rusting burner components below. We repair and replace caps and crowns, including custom copper options for historic homes near the Square, and we document the before-and-after so you know the seal is actually solid.
Firebox Rebuild and Refractory Panel Replacement
The firebox on a gas fireplace takes a beating from heat cycling, and in older Marietta homes that converted from wood to gas, the original firebox was never designed for a gas appliance. Refractory panels crack, mortar joints fail, and sometimes the floor of the firebox starts to shift. We rebuild with industry-standard materials from HeatShield and Gelco. If your gas logs sit crooked, the glass frame won’t seat, or you see crumbling brick inside the firebox, this is usually the repair. A firebox rebuild in Marietta generally runs $900 to $2,400 depending on the fireplace size and panel material.

Trusted Brands We Service in Marietta
We work on all gas fireplace brands common in Cobb County homes, and we stock repair components from HeatShield, Gelco, and Olympia Chimney rather than whatever is cheapest on the warehouse shelf. If your fireplace was installed with a Famco cap or vent, we’re familiar with those systems and can match replacement parts correctly. Because we stock for the Marietta market specifically, the turnaround on most common burner assemblies, thermocouples, and refractory panels is a few days, not a few weeks. We’ll show you the part that failed and what we’re installing in its place, with photos.
Common Gas Fireplace Repair Problems We See in Marietta Homes
- Ignition failure from moisture-damaged burners. Freeze-thaw spalling in original brick chimneys lets water run down into the gas burner assembly, corroding the thermocouple and ignition wiring. This shows up most often in older homes near the Square and along Kennesaw Avenue.
- Hidden chase leaks in prefab chimneys. 1980s and 1990s subdivisions in East Cobb and around Sandy Plains often have zero-clearance fireplaces with a metal chase on the roof. When the flashing at the chase top fails, moisture runs down and corrodes the venting, which can cause a carbon monoxide backdraft. The fireplace still looks fine from the living room. The problem is on the roof.
- Flue blockage from tree debris and nesting. Marietta’s dense oak and pine canopy means uncapped gas flues fill with needles, leaves, and squirrel nests by late spring. The fireplace shuts down, soots the glass, or pushes exhaust into the room. We clear the flue, verify the draft, and install a proper cap so it doesn’t repeat.
- Sooty glass from improper gas-air mixture. Black soot on gas fireplace glass is usually a venting or burner air-shutter problem, not normal operation. If the soot is streaky and returns within days of cleaning, you likely have a partially blocked flue or a burner that needs adjustment. This is a repair call, not a cleaning-only job.

AfterThe Marietta Difference: Gas Fireplace Repair in Older Homes vs. Prefab Subdivisions
Here’s what most companies won’t tell you because they treat every chimney the same. A 1920s Craftsman near the Marietta Square with an original masonry chimney and a gas log set installed in 2005 has a completely different failure profile than a 1987 two-story off Roswell Road with a zero-clearance fireplace and a metal chase. The Craftsman is likely dealing with a deteriorating clay-tile flue, spalling brick from decades of free-water entry, and a firebox that was sized for wood, not gas. The East Cobb prefab is more likely dealing with a flashing leak at the chase top, a rusted vent pipe, or a melted chase cap from improper clearances. Same symptom – fireplace won’t stay lit or smells odd – but the fix is different and the price is different. That’s the information-gain point: we tell you which house you have and why the repair path is what it is, with camera footage to back it up.
Marietta’s Resale Inspection Requirements Change the Repair Conversation
Marietta’s adoption of international building codes means gas fireplace and chimney systems get flagged during home resales more often here than in unincorporated Cobb County. A typical buyer inspection now triggers a Level 2 check: camera scan of the flue interior, a written condition report, and documentation of any prior repairs or liner status. If you’re selling a home in Marietta with a gas fireplace, don’t wait for the inspector to find a cracked liner or uncapped flue. Get the inspection and documentation done before listing, and hand the buyer a clean report instead of a repair credit. We provide the exact photo and condition documentation Marietta inspectors and buyers expect.
In the Whitlock Avenue historic district, we replaced a deteriorating clay-tile flue liner in a 1920s Craftsman whose gas insert had been dumping moisture into the original masonry chimney. The homeowner had converted from wood to a gas log set years earlier but never installed a proper flue liner. Our camera inspection showed spalling brick and a smoke chamber caked with first-degree creosote. We installed a DuraFlex liner sized for the gas appliance, rebuilt the firebox with refractory panels, and added a copper chimney cap, which solved the draft issues and the annual squirrel nesting that had plagued the home every spring. This is the kind of repair that only shows up on a camera. Without it, the owner would have kept paying for cleanings that never fixed the actual problem.

FAQs – Gas Fireplace Repair in Marietta
Yes. Gas fireplaces produce moisture and acidic exhaust that degrade mortar and flue liners over time, and in older Marietta homes with original masonry chimneys, that degradation happens faster than in newer construction. An annual inspection catches cracked clay-tile liners, spalling brick, and early crown damage before they become a $2,000 repair. Call (762) 249-4619 to book an inspection with camera documentation.
That smell is usually moisture hitting creosote residue or soot inside the flue, and it’s common in Marietta because of our humid summers and frequent thunderstorms. If water is getting into the flue through a cracked crown, failed flashing, or an uncapped top, the dampness reactivates old combustion residue and pushes the odor into the house. It’s a water intrusion problem, not a gas leak, but it needs to be fixed because the same moisture is rusting your burner and venting. We camera-scan the flue, pinpoint the leak, and quote the fix.
Yes, and we do this regularly in the historic districts around the Square. The key requirements are a properly sized flue liner, a firebox in sound structural condition, and a chimney cap that prevents water and animal entry. Many original 1920s fireboxes need refractory panel work before the insert can be installed safely. Expect $3,500 to $7,000 for a full insert installation with liner, depending on the fireplace dimensions and the unit you choose.
Yes. Persistent black soot on gas fireplace glass is typically caused by a blocked or undersized flue, a burner air-shutter that’s out of adjustment, or failing venting in a prefab chimney. In Marietta, uncapped flues collecting pine needles and oak leaves are a common trigger this time of year. Cleaning the glass won’t fix the root cause. Call (762) 249-4619 and we’ll diagnose the exact airflow or venting problem before quoting a repair.
Yes. Marietta’s building codes require more thorough chimney documentation during resales than surrounding unincorporated Cobb County. Buyers and inspectors here routinely request a Level 2 inspection with camera footage, a written condition report, and confirmation of liner integrity. If your flue hasn’t been scanned in years, get it done before the listing goes live. We provide the exact documentation Marietta inspectors expect, and if we find a problem, we price the fix honestly so you can decide whether to repair or disclose.
