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 Lilburn
Gas fireplace repair in Lilburn, GA typically runs $185 – $390 for a burner or pilot assembly fix, and most jobs are completed the same day our technician arrives. The more complicated work, like relining a deteriorated flue, starts around $1,800 and goes up from there. If your fireplace won’t light, keeps shutting off, or the flame looks weak and lazy, call us at (336) 863-3889. We’ll send a background-checked technician to your door, and you’ll know their name and see their photo before they arrive.
We spend a lot of time in Lilburn’s older subdivisions, off Burns Road, Rockbridge Road, and around the Killian Hill area. What we find there is predictable. Gas fireplaces installed during Gwinnett County’s 1980s building boom are now far past their rated service lives, and many are vented into chimney stacks that were never designed for gas appliances. That’s why our Gas Fireplace Repair work in Lilburn so often becomes a venting conversation, not just a burner swap.
Why Alcott Chimney Sweep Is Lilburn’s Preferred Gas Fireplace Repair Company
We’ve been repairing and servicing gas fireplaces since 2002. Ruben Castellano runs our operation, and he’s built the company around one idea: a homeowner should never feel pressured into a repair they can’t verify with their own eyes. In Lilburn, where 30-to-50-year-old fireplaces are the norm, that matters more than it does almost anywhere else we work.
Every technician we send to a Lilburn home has passed a background check and identity verification before they ever step onto the property. That’s the Threshold Standard, and it applies to every single visit, no exceptions. The technician wears a uniform, carries a photo ID badge, and shows it at the door. You’ll get their name and photo sent to you before the appointment, so you know exactly who’s coming. We answer our phones with a live person around the clock. When your fireplace smells like gas at 11 p.m., you don’t want a voicemail queue.
Our written guarantee covers every repair. If the work fails within the coverage period, the second visit is free. That’s the 365-Day Done Right Promise. We also give you a written price before any work begins. Not a verbal estimate. A written price. If the scope changes, we stop and get your approval first.
Our Gas Fireplace Repair Services in Lilburn
Gas Fireplace Burner and Pilot Assembly Repair
When a Lilburn homeowner tells us the fireplace won’t stay lit, the first instinct is to blame the thermocouple. Sometimes that’s right. But in our experience around Lilburn’s 1980s subdivisions, the burner often isn’t the problem at all. The flue above it is blocked with pine needles and seed pods from the tree canopy, or the clay tile liner has cracked and killed the draft. We diagnose the actual cause before we replace anything. Burner and pilot assembly repairs in Lilburn typically run $185 – $340, if that’s genuinely what’s needed.
Camera-Verified Flue Liner Inspection and Relining
This is where we earn our keep in Lilburn. We run a camera up the flue, and you watch the screen with us. You see every crack, every spalled tile, every gap in the mortar. Nothing gets recommended from a photo album of “similar chimneys.” Nothing gets quoted on a hunch. If your clay tile liner has failed, we’ll tell you exactly what we saw, show you the footage, and give you options. Meder of those options involves us pressuring you into liner work you can’t verify. We use professional trade liners like DuraFlex, HeatShield, and Olympia Chimney when relining is warranted.
Factory-Built Firebox Service-Life Evaluation
Lilburn’s 1980s tract homes are full of factory-built zero-clearance fireplaces that were rated for 20 – 25 years of service. Many of them are now 10 – 15 years beyond that. We’ll inspect the firebox, check for the original manufacturer’s foil label, and give you an honest assessment of where the unit stands. If the firebox is safe to repair, we’ll repair it. If it’s past its service life and vented into a deteriorated clay flue, we’ll say that plainly, with the evidence to back it up.
Gas Log Set Installation and Conversion
Some Lilburn homes still have wood-burning fireplaces the owners want converted to gas. Others have gas log sets that are cracked, rusted, or simply worn out. We install and service professional-grade gas log sets, and we’ll verify the venting is correct for the appliance. A conversion or new log set in Lilburn runs $350 – $1,200 depending on what’s already in the firebox and what the flue can safely handle.

Trusted Brands We Service in Lilburn
We work with the brands chimney professionals actually specify: Famco, Copperfield, DuraFlex, and HeatShield. Not box-store substitutes. When we replace a burner assembly or reline a flue in a Lilburn home, we use materials built for the job, and we keep common parts stocked for faster turnaround. If your gas fireplace is a zero-clearance unit from the Gwinnett boom era, there’s a good chance we’ve already serviced the exact same model somewhere off Beaver Ruin Road or Indian Trail Lilburn Road this year.
Common Gas Fireplace Repair Problems We See in Lilburn Homes
- Lazy flame and fogged glass from a blocked flue. Lilburn’s dense hardwood and pine canopy drops needles, seed pods, and twigs onto chimney cap after chimney cap. A burner that “won’t light right” is often a vent that can’t breathe.
- Clay tile flue liners cracked by freeze-thaw cycles. Lilburn’s humid Piedmont winters cycle between freezing nights and thawing days. Water seeps into the clay tiles, freezes, and cracks them from the inside. Gas appliances vented into those cracked flues spill combustion gases back into the house.
- Factory-built fireboxes 10 – 15 years past their rated life. The original manufacturer’s label inside the firebox tells the story. When we find a unit built in 1988 still in service, the conversation shifts from “repair” to “is this safe to run at all.”
- Thermocouple and pilot assembly failures from disuse. Lilburn homeowners who only light the gas logs a few times a year may not notice a failing pilot until the first cold snap. By then, the assembly has corroded enough that replacing it is the only fix.
Pricing for Gas Fireplace Repair in Lilburn, GA
Here are the ranges we quote most often in Lilburn, based on the units and flues we actually see in Gwinnett’s 1970s – 1990s housing stock:
| Service | Typical Lilburn Price Range |

| Thermocouple replacement | $120 – $220 |

What drives the cost in Lilburn specifically is the age of the fireplace and the condition of the flue above it. A 1986 zero-clearance unit vented into a cracked clay tile stack is a different job than a 2015 unit with a clean vent. We’ll show you the camera footage, give you a written price before any work starts, and never recommend a repair you can’t see for yourself. Call (336) 863-3889 for a free estimate.

FAQs – Gas Fireplace Repair in Lilburn
The lazy flame and fogged glass usually point to the chimney, not the burner. In Lilburn, where dense tree canopy drops pine needles and seed pods onto chimney caps all year, a blocked flue is often the real culprit. The burner can’t draw combustion air properly, the flame weakens, and moisture condenses on the glass. We’ll run a camera up the flue to confirm the obstruction before we touch the burner. If the vent is clear and the flame still won’t hold, then we look at the pilot assembly and thermocouple. Call (336) 863-3889 and we’ll diagnose it properly.
Look for the manufacturer’s foil label inside the firebox. Most factory-built zero-clearance fireplaces installed during Lilburn’s 1980s build-out were rated for 20 – 25 years. If the label is still there, we can date the unit to the month. We regularly find units from 1985, 1987, 1988 still in service, now a decade or more past their rating. The label combined with a camera inspection tells us what’s still safe and what isn’t. Bring us the make and model, or let us find the label during the visit, and we’ll give you a straight answer.
Lilburn sits in the humid Piedmont, where winter nights dip below freezing and days warm back up. That freeze-thaw cycle moves water into the porous clay tiles of older chimneys, and the water expands when it freezes. Over 30 or 40 winters, the tiles crack and spall. The mortar joints erode too. A gas appliance vented into that damaged flue can’t draft properly, and combustion gases can spill back into the living space. The climate doesn’t just age the fireplace; it ages the chimney above it faster than in drier markets.
We can replace the pilot assembly without a camera inspection, but we won’t warranty any repair that ignores the condition of the flue. If the pilot is failing because the flue is blocked or the liner has cracked, a new pilot assembly is a temporary fix at best. Our camera inspection is included when we diagnose a gas fireplace repair in Lilburn, and you watch the footage with us. We’d rather show you why the fix is needed than sell you a part that won’t last. Call (336) 863-3889 and we’ll explain the process before we ever schedule the truck.
Yes, and in Lilburn it’s more important than the average gas fireplace owner realizes. The national standard applies to any chimney that vents combustion gases, whether you light the fireplace once a year or every weekend. In Lilburn’s aging 1970s – 1990s housing stock, a full year without an inspection means a full season of pine needles packing into the cap, freeze-thaw cycles working on the clay liner, and a firebox that’s potentially a year deeper past its service life. The annual inspection is not about how often you use the fireplace. It’s about what’s happening to the flue while you’re not using it. Call (336) 863-3889 to schedule an inspection before the next cold snap.
What We Found Off Beaver Ruin Road
In one of the 1980s subdivisions off Beaver Ruin Road, a homeowner called us about a gas fireplace that lit but wouldn’t hold a flame. The flame lifted off the burner, and the draft was lazy. We pulled the original foil manufacturer label still glued inside the heat-stained firebox and matched the serial to a zero-clearance unit built during the Gwinnett boom. It was roughly a decade past its rated service life. The burner wasn’t the only problem. The camera showed a thirty-year-old clay flue liner above it that had spalled, with cracked tiles and eroded mortar, and it was undersized for the appliance to begin with. We replaced the burner assembly, relined the stack with an Olympia Chimney liner to restore proper draft, and the homeowner watched every single cracked tile on our camera screen before we quoted a dollar.
That’s the reality of gas fireplace repair in Lilburn. This isn’t a city of 2015-era gas inserts in newly built homes. It’s a city of 1970s ranch houses off Burns Road, 1980s colonials off Rockbridge Road, and early-1990s subdivision builds near Killian Hill, most of them still running the original fireplaces and the original chimneys. Gas appliances get vented into clay-tile flues that were never sized or rated for them. Factory-built fireboxes sit 10 – 15 years past their manufacturer service life. The repair conversation in Lilburn is often a venting and liner conversation wearing a burner-repair costume.
We won’t write a repair quote on a unit that should legally be replaced, and we won’t recommend liner work without showing you the camera footage that backs it up. Nothing gets recommended that you can’t see for yourself. That’s the whole point of what we do, and it’s why Lilburn homeowners keep our number on the fridge. Call (336) 863-3889 for a free estimate, and you’ll get a written price before any work begins, a written guarantee on every repair, and a technician whose name and photo you’ll already have.
