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 Stone Mountain
Gas fireplace repair in Stone Mountain runs $165 to $485 for most common fixes, with a full stainless liner install on an older Village chimney typically landing between $2,800 and $5,400 depending on flue height and access. We get to Stone Mountain homes same-week in nearly all cases, and we never recommend a liner replacement, smoke chamber rebuild, or any other repair without running a camera first and showing you the footage. If you’re in the 30083, 30087, or 30088 zip codes and your gas logs are burning lazy, sooty, or smelling like exhaust, call (336) 863-3889 and we’ll schedule a diagnostic visit with a written price before any work starts.
Stone Mountain’s housing stock throws a specific set of problems at gas fireplaces. More than half the homes here are brick ranches and split-levels built between the late 1950s and early 1980s, and most still vent through their original clay-tile flues. Those tiles crack, offset, and spall after 50-plus years of Georgia humidity cycling and freeze-thaw stress, and when a gas log insert gets retrofit into that aging stack without a properly sized stainless liner, you get exactly what we find on service calls all over town: lazy flames, soot buildup, and combustion byproducts spilling back into the living space. We know these chimneys because we work on them every week, from the Village to the neighborhoods along Rockbridge Road and down toward Redan Road.
Why Alcott Chimney Sweep Is Stone Mountain’s Preferred Gas Fireplace Repair Company
We’ve built our reputation in Stone Mountain on a simple rule: nothing gets recommended unless you can see the reason on camera. Too many homeowners here have been told they need a four-thousand-dollar liner or a full smoke chamber rebuild based on a glance down the flue and a salesman’s word. That’s not how we work. Every diagnostic includes a camera inspection, and before we quote anything, we show you the footage. You see the cracked tile, the offset section, the missing mortar. You make the call with your own eyes.
Ruben Castellano has run Alcott Chimney Sweep since 2002, and the company operates under the Threshold Group family of home-service companies. Every technician who shows up at a Stone Mountain home is background-checked, identity-verified, and sent to you by name and photo before the visit. They’ll show you a photo ID badge at the door. Every time. No exceptions. That’s the Threshold Standard, and it’s not an optional upgrade.
On top of that, every repair comes with a written guarantee. If the repair fails within the coverage period, we come back free. And the price you’re quoted before work begins is the price you pay. No add-ons, no surprise labor charges at the end. A live person answers our phone around the clock, so if you smell gas or smoke at 11 p.m. in the middle of a Stone Mountain December, you won’t get a voicemail.
Our Gas Fireplace Repair Services in Stone Mountain
Gas Fireplace Inspection with Camera-Verified Flue Liner Review
A proper gas fireplace inspection in Stone Mountain isn’t a visual glance. We run a camera the full length of the flue and document the condition of every tile section, the smoke chamber, and the damper. For the 1960s and 1970s brick ranches that dominate neighborhoods like Sherwood Forest and the areas off South Hairston Road, this review almost always finds something: hairline tile cracks, eroded mortar joints, or a liner that was never sized for the gas appliance venting into it. You get the photos. You get the narrative. You decide what’s urgent and what can wait.
Stainless Steel Flue Liner Sizing and Installation for Gas Appliances
This is the single most needed gas fireplace repair in Stone Mountain, and it’s the one where we spend the most time correcting bad advice from other companies. A gas log set produces lower flue temperatures than a wood fire, which means the chimney needs a smaller cross-sectional liner to maintain proper draft. When a gas insert gets dropped into an original clay-tile flue built for wood, the flue is often two to three times too large. The exhaust cools, the draft stalls, and combustion byproducts linger. We size and install stainless liners from Olympia Chimney and Copperfield, matched precisely to the appliance and the flue’s actual dimensions, not a guess.
Smoke Chamber and Damper Repair for Gas Log Inserts
The smoke chamber sits between the firebox and the flue, and in Stone Mountain’s older brick ranches it’s frequently the most deteriorated part of the system. Georgia’s humid subtropical summers accelerate mortar erosion between burns, and by the time we’re called out, the smoke chamber walls are often shedding grit and leaving gaps where exhaust can escape into the chase. For gas inserts, a leaky smoke chamber means combustion byproducts and carbon monoxide can migrate where you don’t want them. We repair and reseal smoke chambers with the same professional-grade materials we use on full Gas Fireplace Repair jobs, and we damper-check every gas appliance we touch.
Gas Log Set Ignition and Burner Service
Won’t light? Pilot keeps dropping? Flames uneven or yellow at the tips? These are the calls we make most often in Stone Mountain’s winter months, when December through February temperatures dip low enough to drive consistent fireplace use. We service thermocouples, thermopiles, gas valves, and burner tubes, and we stock common replacement parts for the brands installed throughout Stone Mountain, so we rarely need a second trip. Same-day completion on most ignition repairs, and the written guarantee applies to every part and every labor hour.

Trusted Brands We Service in Stone Mountain
We install and service the brands chimney professionals actually specify, not box-store substitutes. That means Olympia Chimney and Copperfield stainless liner systems, Famco dampers and caps, and DuraFlex connector components when a flexible run is the right call. Because we carry these lines regularly, Stone Mountain customers aren’t waiting a week for a part to ship from a distributor. If you’ve got a gas insert or log set from a major manufacturer and you’re not sure whether it’s venting correctly, we’ll tell you plainly what it needs and what it doesn’t. No brand loyalty. Just what the camera shows.
Common Gas Fireplace Repair Problems We See in Stone Mountain Homes
- Gas inserts venting into oversized, unlined clay flues. This is the Stone Mountain signature problem, especially in the historic Village blocks near Main Street, and it produces the lazy, sooty flame and exhaust smell homeowners describe to us constantly. The flue was built for wood, the appliance was retrofit for gas, and no one ever addressed the liner mismatch.
- Cracked and offset clay flue tile sections from decades of humidity and freeze-thaw cycle. Stone Mountain’s original clay tiles are now 50 to 70 years old, and Atlanta’s winter temperature swings, combined with summer humidity, have opened gaps that let gas exhaust leak into the chimney chase instead of venting up and out.
- Deteriorated mortar crowns and spalling face brick allowing water intrusion. Water from crown erosion seeps down through the masonry, rusts the damper assembly, accelerates flue liner decay, and worsens fireplace draft. We see this on the brick ranch stock all over Stone Mountain, from Redan Road to the cul-de-sacs off Memorial Drive.
- Lazy pilot lights and thermocouple failures from moisture and debris. A pilot that won’t stay lit is often a moisture problem, not a gas problem. The same water intrusion that eats the crown and liner also corrodes the ignition components, and in Stone Mountain’s humid climate, this cycle repeats until the water path is fixed.
Pricing for Gas Fireplace Repair in Stone Mountain, GA
Here’s what Stone Mountain homeowners should expect to pay. A diagnostic visit with camera inspection runs $165 to $225, and that fee is credited toward any repair we do on the same visit. Ignition and thermocouple repairs typically land between $185 and $340. Smoke chamber resealing runs $450 to $1,200 depending on chamber size and access. A stainless liner install for a gas appliance runs $2,800 to $5,400, with the spread driven by flue height, roof pitch, and whether we’re working on a single-story ranch or a taller Village chimney. Before any work begins, you get a written price. If we find something during the job that changes the scope, we stop, show you, and get your sign-off. No surprises at the end.
And one more thing about pricing: we’ll tell you plainly when work can wait. A hairline tile crack in a gas-only flue that’s drafting fine may not need immediate action. A full liner replacement quote on a chimney that shows no camera evidence of liner failure? We’ll tell you it’s not needed. That’s the whole point of a camera-first approach.

FAQs – Gas Fireplace Repair in Stone Mountain
Very likely yes, and this is the condition we encounter more in Stone Mountain than anywhere else in eastern DeKalb County. In the historic Village blocks near Main Street, late-1800s and early-1900s masonry chimneys were retrofit with gas log inserts decades ago, and in nearly every case the insert was dropped into the original clay flue without a properly sized stainless liner being installed. The result: gas exhaust venting into a flue far too large for the appliance, which kills draft and lets combustion byproducts linger or spill back. We were called to a 1908 masonry chimney off Main Street where the homeowner’s gas log set had been running with a lazy, sooty flame for two seasons. Our tech ran a camera down the flue and found the appliance venting into an oversized unlined clay stack with offset tile sections, so we dropped in a properly sized stainless liner and re-sealed the smoke chamber. The draft snapped back to a steady blue flame the same afternoon. Call (336) 863-3889 for a camera-verified answer on your specific chimney, not a guess.
It doesn’t, unless you’re using a wood-burning fireplace that was later converted to gas, which is extremely common in Stone Mountain homes. If you previously burned yard-fallen pine, the existing creosote deposits remain in the flue, and a gas appliance venting through that same chimney can still be compromised. Pine from Stone Mountain’s dense stands of loblolly and mixed hardwoods deposits creosote at two to three times the rate of seasoned hardwood, so if you’re converting from wood to gas, the flue needs a thorough sweep and camera inspection before the appliance goes in. Call (336) 863-3889 and we’ll tell you what’s in your flue.
A Level 2 inspection includes everything in a Level 1 visual check plus a full camera scan of the flue interior, the smoke chamber, and the damper assembly. For a 1960s brick ranch in neighborhoods like Sherwood Forest or the streets off South Hairston Road, this is the inspection that catches the tile cracks, offset sections, and water intrusion points that a visual-only look would miss. It’s the standard we recommend for any Stone Mountain gas fireplace that hasn’t been inspected in three years or more, and you’ll get the camera footage to review yourself. Estimates for a Level 2 are free – call (336) 863-3889.
You’re describing poor draft, and in Stone Mountain homes the most common cause is an oversized or deteriorated flue liner. Gas exhaust cools too quickly in an oversized flue, the draft stalls, and combustion byproducts linger in the firebox instead of venting out. It can also be a partially clogged flue, a failed damper, or a smoke chamber gap. This is a carbon monoxide risk, so don’t run the fireplace until it’s checked. Call (336) 863-3889 and we’ll diagnose it with a camera, not a guess.
Yes, and the damage is often more advanced than homeowners expect. Atlanta’s humid subtropical summers accelerate mortar erosion and efflorescence inside the flue, while the winter freeze-thaw cycles you get in Stone Mountain from December through February push moisture into cracks and widen them. By the time we run a camera at an annual cleaning, the crown and liner damage is frequently well past what the homeowner assumed was there, given how relatively mild the winters are. This is why we recommend a camera inspection every three years for gas fireplaces in Stone Mountain, and annual for any converted wood-burning chimney. Call (336) 863-3889 to schedule.
If your gas fireplace in Stone Mountain is acting up, or you just want to know what’s actually going on inside that flue before someone tries to sell you a liner, call us at (336) 863-3889. You’ll talk to a live person. You’ll get a written price before any work starts. And you’ll see the camera footage with your own eyes before anyone recommends a dollar of repair. That’s how we’ve done it since 2002, and that’s how we’ll do it at your house.
