We’ve been doing this since 2003, and every repair starts with a written price before any work begins. Call (762) 249-4619 when your fireplace isn’t firing right, and we’ll get someone to your door in a tracked window, not a four-hour guess.
Why Hadley Chimney Marietta Is Mableton’s Preferred Gas Fireplace Repair Company
Mableton homeowners call us because we show them what’s wrong before they spend a dollar. That matters here more than most places. The housing stock off Floyd Road and through the older sections of Mableton was largely built in the 1960s through 1980s, and those brick ranch and split-level homes have chimneys with clay tile liners that crack, mortar joints that open up, and dampers that corrode. When a gas fireplace stops drafting or starts smelling, the cause is rarely the burner itself. It’s usually the chimney it’s venting into.
Cory Mitchell leads our gas fireplace repair work, and he’s built the team around one rule: no liner replacement, no damper job, no cap install gets recommended unless the homeowner sees the camera footage first. That’s not a sales pitch. It’s the only way to keep honest work honest. We back every repair with our 365-Day Done Right Promise, a written guarantee, and a free second visit if the repair fails within that year. Mableton customers also get live arrival tracking and before-and-after photos through the Relay Visibility Guarantee, so you know who’s coming, when they’ll arrive, and exactly what was done after they leave.

Our Gas Fireplace Repair Services in Mableton
Flue Liner Inspection and Repair
Most gas fireplace problems in Mableton trace back to the flue liner. In older brick homes, especially the ranch styles around Mableton Estates and the neighborhoods south of the East-West Connector, clay tile liners crack under freeze-thaw cycles. When that happens, exhaust gases can seep into wall cavities instead of venting outside. We run a camera down every flue before touching the gas components. If the liner is cracked, you’ll see the footage. If it’s sound, you’ll see that too, and we won’t recommend a replacement that isn’t needed.

Damper Replacement
Rusted dampers are the single most common repair we make in Mableton. Homes without chimney caps let rain fall straight down the flue, and the damper is what catches it. A corroded damper won’t seal properly, which means combustion gases from your gas logs spill back into the living room. We replace dampers with Famco parts when the chimney size allows it, and we always recommend installing a rain cap at the same time. Half the damper replacements we do in Mableton are on homes within a mile of Nickajack Creek, where spring storms hit hardest.

Chimney Cap Installation
A chimney cap is the cheapest insurance you’ll ever buy for a gas fireplace in Mableton. The humid subtropical climate means rain, and plenty of it. Homes off Floyd Road without caps get water down the flue with every storm system that rolls through. That water rusts dampers, degrades mortar, and eventually works its way into ceilings and walls. We install stainless caps sized to your flue, and we’ll show you the before-and-after photos so you can see what was actually covered.

Gas Log and Burner Service
When the pilot lights but the main burner won’t stay on, the thermocouple or thermopile is usually the culprit. In Mableton’s newer subdivisions built in the 1990s and 2000s, we also see issues with prefabricated metal flues that corrode from humid summers and poor draft. That corrosion creates backpressure, and the safety sensors shut the burner down. We service all major gas log brands and carry common replacement parts on the truck, so most burner and pilot repairs are done in one visit.

AfterCommon Gas Fireplace Repair Problems We See in Mableton Homes
- Water-damaged dampers from missing rain caps. Older brick chimneys off Floyd Road often lack caps entirely. Rain pours in, the damper rusts, and the gas fireplace starts drafting poorly. We fix the damper and the root cause in one trip.
- Cracked clay tile liners in 1960s – 80s ranches. Mableton’s freeze-thaw winters put stress on masonry chimneys built forty or fifty years ago. Cracks let exhaust escape, and camera inspection is the only way to confirm the damage before you commit to a repair.
- Corroded prefab flues in 1990s subdivisions. The two-story traditional and craftsman homes in Mableton’s newer neighborhoods vent gas fireplaces through metal flues. Humid summers condense inside those flues, causing rust, draft failure, and carbon monoxide risk.
- Pilot lights that won’t stay lit. This is often a thermopile or thermocouple failure, but in split-levels throughout Mableton, we also find venting issues that cause the flame to lift and the safety circuit to trip. We diagnose both before quoting any repair.
Pricing for Gas Fireplace Repair in Mableton, GA
Here are real numbers for the Mableton market. A standard gas log service, including pilot cleaning and thermostat check, runs $145 to $225. Damper replacement typically falls between $260 and $420 depending on whether we’re installing a Famco top-sealing damper or a throat-mounted replacement. Chimney cap installation runs $185 to $340 with the cap included. Flue liner inspection with a camera runs $95 to $150, and if that inspection reveals damage, HeatShield liner repair starts around $650 for a partial section. Full liner replacement on a two-story Mableton home can reach $2,500 to $4,000, but we never recommend that work without showing you the camera footage. Call (762) 249-4619 for a free estimate and a written price before we touch anything.
One thing worth saying plainly: in Mableton, gas fireplace repair often starts with fixing water damage before the burner is even touched. We pulled a corroded Famco damper from a 1970s brick ranch in Mableton Estates where a missing chimney cap had let rain pour down the flue for years. Our crew replaced the damper, installed a new cap, and then serviced the gas logs, showing the homeowner camera footage of the rusted flue liner before we touched anything. That’s the order things happen in: diagnose the chimney, fix the water entry, then tune the gas system.

FAQs – Gas Fireplace Repair in Mableton
The smell is almost always water hitting built-up creosote or ash inside the flue. In Mableton homes without chimney caps, rain soaks the flue, mixes with residue, and the damp wood-fire smell pushes into the living space when the gas fireplace runs. The fix is a chimney cap and a proper flue cleaning. Call (762) 249-4619 and we’ll camera the flue to confirm.
Yes. Gas fireplaces still vent carbon monoxide, and a cracked flue liner or blocked chimney is dangerous even with occasional use. In Mableton’s humid climate, prefab metal flues corrode and clay liners crack regardless of how often you run the fireplace. An annual camera inspection runs under $150 and tells you exactly what condition your flue is in.
It depends on the condition of the clay liner. Many 1980s homes in Mableton have liners with freeze-thaw cracks that make direct venting unsafe. We’ll run a camera down the flue and show you what we see. If the liner is intact, a gas insert conversion is usually straightforward. If it’s cracked, HeatShield repair or a new liner solves the issue before the insert goes in. Call (762) 249-4619 and we’ll give you an honest assessment.
Yes. Once the animal is removed, we typically find nesting material, debris, and sometimes damage to the damper or flue liner. We’ll clean the chimney, camera the flue to check for structural damage, and service the gas fireplace. Many Floyd Road homes also need a chimney cap installed at the same time, since an open flue is what let the raccoon in to begin with.
The thermopile is the most likely culprit. It generates the voltage that holds the gas valve open, and when it fails, the pilot stays lit but the burner won’t fire. In Mableton split-levels, we also check for venting restrictions caused by corroded prefab flues, which cause the same symptom. We’ll test both during the visit and show you what’s actually failed before quoting the repair. Call (762) 249-4619 for a free estimate.
