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.

Our crews run repairs all over Lawrenceville, from the subdivisions off Sugarloaf Parkway and Old Peachtree Road to the older brick homes surrounding the historic downtown square off Crogan Street. We know which side of the 1980s buildout your house sits on almost before you tell us the address, and that matters more than you’d think when it comes to gas fireplaces. Ruben Castellano built this company on straight answers and camera proof, and that’s how every Lawrenceville job gets done.
Why Alcott Chimney Sweep Is Lawrenceville’s Preferred Gas Fireplace Repair Company
Since 2002, we’ve worked on thousands of factory-built fireplaces across Gwinnett County, and Lawrenceville’s subdivision stock from the 1985 to 2005 era is a specialty, not an afterthought. Our Gas Fireplace Repair techs know the failure patterns on Heat-N-Glo, Heatilator, and Superior units that dominate these neighborhoods, and they know the older masonry flues near the square run differently entirely. That local knowledge means fewer misdiagnoses and fewer unnecessary liner quotes.
We schedule Lawrenceville calls as local dispatch from our Atlanta office, with crews that know the traffic reality of Highway 316, Lawrenceville Highway, and Sugarloaf Parkway. You’ll know the technician’s name and see their photo before we arrive. Every Alcott technician passes a background check and identity verification under the Threshold Standard before they ever step onto your property, and they’ll show you a photo ID badge at the door. No exceptions, no surprises.
Every Gas Fireplace Repair in Lawrenceville job includes a written price before work begins and a written guarantee on every repair. If the repair fails within a full year, the second visit is free. That’s our 365-Day Done Right Promise, and it’s been our non-negotiable standard for over two decades.
Our Gas Fireplace Repair Services in Lawrenceville
Gas Fireplace Diagnostics With Camera Evidence
The most common Lawrenceville call we get is a gas fireplace that shuts off after 10 or 15 minutes, usually with soot streaks forming on the brick veneer above the firebox. When we arrive, the first question is always zero-clearance or masonry, because the repair path splits hard from there. We run a diagnostic on the pilot assembly, thermocouple or thermopile, flame sensor, and gas valve, then we put a camera up the chase or flue and show you exactly what we’re looking at on the monitor. In Lawrenceville’s humid climate, the culprit is usually a rusted flame sensor or a sheet-metal flue pipe that’s eaten through at the chase cover gasket, not the firebox itself. You see it before you pay for it.
Level 2 Inspection of Factory-Built (Zero-Clearance) Chase and Flue Pipe
If your Lawrenceville home was built between 1985 and 2005, your “chimney” is almost certainly a factory-built metal chase, not masonry. A Chimney Inspection - Lawrenceville at Level 2 uses a camera to evaluate the entire flue system, from the firebox collar up through the chase cover, looking for rust-through, separated pipe sections, and deteriorated gaskets that let rain into the chase. Lawrenceville’s year-round humidity accelerates rust on these sheet-metal components faster than almost anywhere else in metro Atlanta, so we generally recommend this inspection annually for subdivision homes with active gas fireplaces. It is the single most useful thing you can do to catch a $400 component replacement before it turns into a $4,000 firebox swap.
Vented and Vent-Free Gas Log Set Installation and Repair
Lawrenceville’s rapid resale market means gas log sets get swapped between vented and vent-free configurations all the time, often without anyone checking the firebox listing. We see this constantly: a vent-free log set dropped into a firebox only listed for vented operation, or the reverse, and the result is soot staining on the surrounding brick veneer and a carbon monoxide risk the homeowner can’t see. We’ll identify what your firebox is actually listed for, correct the setup if it’s wrong, and install listed log sets that match the manufacturer’s spec. We carry and install professional brands like Famco and Copperfield, not box-store substitutes.
Chimney Cap Installation Ahead of April
If you’d rather not share your gas fireplace flue with a federally protected chimney swift colony, the time to cap it is now, before April. Chimney swifts arrive in Lawrenceville’s subdivisions every spring and will reliably colonize any uncapped flue they can find. Once they’re nesting, the Migratory Bird Treaty Act protects them until they leave in October, which means your fireplace stays unusable all summer. A properly fitted cap with a screen costs a fraction of a chimney swift eviction, and we install them routinely across Snellville, Grayson, and the Collins Hill area of Lawrenceville.

Trusted Brands We Service in Lawrenceville
We service and install the brands that actually dominate Lawrenceville’s housing stock, so parts turnaround is fast and we rarely need a second visit for a backorder. That includes Heat-N-Glo, Heatilator, Superior, Majestic, and Mendota units found throughout Gwinnett County’s subdivision buildout. We carry professional trade materials from Gas Fireplace Repair manufacturers like DuraFlex for flue relining and HeatShield for firebox resurfacing, along with Famco and Copperfield components. When a 1990s zero-clearance unit needs a flue section replaced, we don’t improvise with whatever the hardware store had in stock. We use the same brands chimney professionals specify.
Common Gas Fireplace Repair Problems We See in Lawrenceville Homes
- Rust-through on sheet-metal flue pipe and chase cover gaskets. Lawrenceville’s persistent humidity doesn’t care how well your subdivision HOA maintained the exterior. Water finds its way into the chase, rusts the flue pipe at the gasket line, and suddenly your fireplace shuts down or smells like wet metal. The repair is a component swap, not a cleaning.
- Vented to vent-free log swaps without checking the firebox listing. Lawrenceville’s fast resale market means fireplaces get “improved” by flippers and previous owners who don’t check the listing. The result is soot on the brick veneer, a pilot that won’t stay lit, and a carbon monoxide issue the homeowner can’t see. We show it on camera.
- Clay-tile flues near the downtown square venting modern gas appliances. Homes built before 1960 off Crogan Street and around the Gwinnett County Courthouse often run gas logs through original clay tile liners that were never sized or listed for that appliance. Spalling tile and reversed draft show up as a firebox that won’t stay lit and a smoke chamber that condenses moisture instead of exhausting it.
- Flame sensors and thermocouples caked with oxide. Lawrenceville’s short, inconsistent burn sessions mean incomplete combustion and faster oxide buildup on flame sensors. This is the classic “runs 10 minutes then shuts off” problem, and it’s usually a $145 to $260 repair if caught before the sensor fails completely.

FAQs – Gas Fireplace Repair in Lawrenceville
In most Lawrenceville subdivision homes, that shutdown pattern means a fouled flame sensor or a failing thermocouple, not a gas supply problem. The sensor’s job is to confirm the pilot flame is actually lit before the gas valve opens fully, and when it’s coated in oxide from Lawrenceville’s short, inconsistent burn sessions, it reads a false “no flame” signal and shuts the valve. It’s usually a $145 to $260 repair in Lawrenceville, and we’ll show you the sensor under magnification before replacing it. Call (336) 863-3889 to schedule a diagnostic.
Yes, and in Lawrenceville the reason is moisture, not creosote buildup. Your factory-built metal chase and flue pipe are rusting from the outside in, accelerated by humidity that never really stops, even when you’re not burning. An annual Level 2 inspection with a camera catches rust-through at the chase cover gasket and separated pipe sections before they become firebox failures. For pre-1960s masonry flues near the downtown square, the annual check catches spalling clay tile and draft reversal before carbon monoxide becomes an issue.
That’s a factory-built zero-clearance fireplace, and it’s what we repair more than anything else in Lawrenceville. The “chimney” is a framed wood chase with vinyl or stucco cladding, and inside runs a sheet-metal flue pipe that rusts from Lawrenceville’s humidity long before the firebox itself fails. Component-level repairs, like a flue pipe section or chase cover gasket replacement, run $425 to $900, and we carry the professional trade materials to do them right the first time. Full firebox replacements are rarer and start around $2,400.
Because chimney swifts arrive in Lawrenceville every April, and once they nest in your uncapped flue, federal law protects them until they leave in October. That means an unusable fireplace all summer and a cap installation you can’t do until fall. A chimney cap with a proper screen prevents the whole problem, and spring is the calm before the rush. We install caps throughout Lawrenceville’s subdivisions starting in late winter so homeowners are covered before the birds show up.
Yes, and you’ll see it on the camera monitor before we quote anything. Nothing gets recommended on a Lawrenceville job without camera evidence the homeowner can see for themselves, and we’ll say plainly when a flue or firebox can safely wait. If we recommend a DuraFlex liner or a HeatShield resurfacing, it’s because the camera shows a real failure, not because it’s a profitable add-on. The written price comes before any work starts, and the written guarantee covers it for a full year. If it fails, the second visit is free. Call (336) 863-3889.
