Why Alcott Chimney Atlanta Is Druid Hills’s Preferred Gas Fireplace Repair Company
Alcott Chimney Atlanta has served homeowners since 2002, and we’ve worked on more Druid Hills gas fireplaces than most companies see in a decade. Our Gas Fireplace Repair team knows the difference between a firebox crack that’s cosmetic and one that’s moving carbon monoxide into a bedroom. That distinction matters here more than almost anywhere in Atlanta, because Druid Hills has a problem most cities don’t: attached historic homes sharing chimney stacks. When one unit’s gas appliance leaks exhaust into a shared flue, the adjacent home can get the carbon monoxide even though its own fireplace is fine.
Every technician we send into Druid Hills is background-checked, identity-verified, and uniformed. That’s the Threshold Standard, and it’s non-negotiable. You’ll get the tech’s name and photo before we arrive, and they’ll show a photo ID badge at the door. We don’t subcontract. We don’t send “a guy.” We send a specific person you already know is coming.
We also put our guarantee in writing. Every repair carries a written warranty, and if the repair fails, the second visit is free. That’s the 365-Day Done Right Promise, and it applies to every job we do in Druid Hills, from a thermopile replacement to a full flue liner install.
Ruben Castellano founded Alcott Chimney Sweep with a simple rule: show the customer the problem before asking them to pay to fix it. If you’re told your gas fireplace needs a new liner or a rebuilt firebox, we’ll show you the camera footage. You’ll see exactly what we see. No scare-selling, no mystery repairs, and a written price before any work starts.

Our Gas Fireplace Repair Services in Druid Hills
Flue Liner Inspection and Repair
The biggest safety issue we find in Druid Hills homes isn’t the gas fireplace itself. It’s the flue behind it. Older homes in this area, especially those built before 1940, often have original terra cotta liners that have cracked or separated at the mortar joints. When that happens, exhaust from your gas fireplace, or from a neighbor’s appliance on a shared stack, can leak into wall cavities or adjacent rooms. We run a camera through the flue during every Chimney Inspection - Druid Hills visit. You see the footage. If a liner is needed, we install DuraFlex stainless steel liners, the professional-grade system specified by chimney technicians, not the thin box-store foil. A flue liner replacement for a typical Druid Hills two-story home typically runs $1,800 to $3,400 depending on height and access.
Chimney Cap Installation and Replacement
Druid Hills has one of the densest tree canopies in Atlanta. That’s part of what makes the neighborhood beautiful, but it also means leaves, twigs, and squirrel nests end up in chimneys constantly. A missing or rusted chimney cap lets all of that fall into the flue, where it blocks gas exhaust and forces carbon monoxide back into your living room. We stock and install full-size stainless steel and copper chimney caps in standard sizes for Druid Hills chimneys. For an old home with an unusual flue size, we’ll measure and custom-order from Olympia Chimney. A cap with installation in Druid Hills typically runs $220 to $480.
Damper Adjustment and Sealing
Gas fireplaces in Druid Hills lose a surprising amount of conditioned air through leaky dampers. The humid subtropical climate means your cooling system works hard most of the year, and an old cast-iron damper that doesn’t seat properly lets that cool air escape up the flue. It also allows humidity into the chimney, which is one reason we see so much efflorescence and spalling on brick chimneys in this neighborhood. We adjust or replace dampers, and for gas logs we install top-sealing dampers with a proper vent clip so you’re not running the fireplace with the damper fully open when it should be partially closed. Damper work in Druid Hills typically runs $140 to $320.
Draft and Cross-Contamination Testing
This is the service that matters most in attached Druid Hills residences. When two or more homes share a chimney stack, each flue should be completely isolated from the others. In homes built before modern code requirements, they often aren’t. We test draft pressure, check flue isolation, and use inspection cameras to verify that exhaust from your fireplace exits the chimney and doesn’t backdraft into your living space, or worse, enter through the flue connected to your neighbor’s firebox. If we find a cross-contamination path, we’ll show it to you on camera and give you a written quote to fix it. Draft testing on its own in Druid Hills runs $95 to $160, and it’s free with any repair.

Trusted Brands We Service in Druid Hills
Gas fireplaces aren’t all the same. In Druid Hills we see a lot of older Heatilator and Majestic units from the 90s, plus newer direct-vent models from Napoleon, Valor, and Mendota. We service all of them. For repairs, we use professional trade materials: DuraFlex for flue liners, HeatShield for resurfacing damaged masonry flues, Olympia Chimney for caps and termination systems, and Famco for venting components. We carry common replacement parts on our trucks, so in many cases we can complete a repair in a single visit. When we do need a part, the Druid Hills supply houses are close, and our turnarounds are short. We never substitute an off-brand thermocouple or a generic replacement log set. If your fireplace was designed for a specific part, that’s the part we install.

AfterCommon Gas Fireplace Repair Problems We See in Druid Hills Homes
- Shared flue cross-contamination. In attached homes on streets like Oakdale Road and Fairview Road, a failing liner in one unit can send a neighbor’s carbon monoxide into your firebox. If you notice a gas smell when your fireplace is off but the weather is cold, this is often the cause. We can test for it.
- Blocked flues from dense tree cover. The mature oaks and maples in Druid Hills drop enormous amounts of debris every fall. Without a chimney cap, that material accumulates in the flue and blocks gas exhaust. Soot staining around the fireplace opening is a telltale sign.
- Unlined masonry flues in pre-1940 homes. Many original fireplaces in Druid Hills, especially in the Olmsted-designed sections, were built for wood fires and never lined with a modern flue system. Gas exhaust is wetter than wood smoke, and it accelerates spalling and mortar failure. If your gas insert was added without addressing the original flue, you likely need a liner.
- Spalling brick and efflorescence from humidity cycling. Atlanta’s humid summers and occasional winter freezes cause moisture to penetrate chimney brick. When water freezes, it expands and pops the brick face. We see this constantly on the tall, ornate chimneys of Druid Hills’s Georgian and Tudor homes. It’s a structural issue that also compromises draft, which then affects gas fireplace performance.

FAQs – Gas Fireplace Repair in Druid Hills
You typically can’t tell on your own, which is why this is a code-level concern. Signs include a gas or exhaust smell in your home when your own fireplace is off, warm air coming from an unused fireplace in winter, or carbon monoxide detector activations that don’t trace to an obvious source. A draft test with a pressure gauge and a camera inspection of the shared flue can confirm whether isolation has failed. If we find a cross-contamination path, we’ll install a new insulated liner specific to your unit and cap the unused flue openings. Call (762) 356-6423 – a carbon monoxide detector that keeps going off is not something to wait on.
Because Druid Hills has one of the densest tree canopies in Atlanta, and gas fireplaces still vent exhaust through the chimney. Leaves, pine straw, squirrel nests, and even raccoon intrusions are common in flues throughout this neighborhood. A missing cap allows that debris to block the gas exhaust path, which forces carbon monoxide back into your home. A cap also keeps rain out, which matters because Atlanta’s humid climate already creates enough moisture issues. A chimney cap in Druid Hills typically runs $220 to $480 installed. Call (762) 356-6423 for a quote – a cap is one of the least expensive safety improvements you can make.
No, and this is one of the most common dangerous conditions we find in Druid Hills. Gas exhaust is wetter than wood smoke and more corrosive to old mortar. In an unlined masonry flue from the 1920s, that moisture soaks into the brick and mortar, causing spalling and flue deterioration. Once the flue fails, exhaust can leak into wall cavities, attic spaces, or an adjacent unit on a shared stack. If you have a gas insert with an unlined original flue, we’ll recommend a stainless steel liner, typically DuraFlex, installed to modern code. Liner costs for a two-story Druid Hills home typically run $1,800 to $3,400. Call (762) 356-6423 and we’ll start with a camera inspection so you can see the condition for yourself.
Annually, and here’s why: shared flue stacks add a variable you can’t control, which is your neighbor’s use. Even if you only burn a gas log set twice a year, the adjacent unit’s gas water heater or furnace may vent through the same stack every single day. That continuous use accelerates liner deterioration. The National Fire Protection Association recommends annual inspection for gas fireplaces, regardless of usage, and in attached Druid Hills homes we consider that a minimum. Our standard gas fireplace inspection in Druid Hills runs $150 to $250 and includes camera footage of the full flue. Call (762) 356-6423 to schedule.
Yes. The fix is flue isolation. We install a new stainless steel liner in your flue, properly sized for your gas appliance, and we cap the unused openings in the shared masonry stack. This creates a dedicated, sealed exhaust path for your fireplace only. In one 1920s Tudor on Oakdale Road in Druid Hills, a homeowner called us about a faint gas odor in an upstairs bedroom. The cause turned out to be a crumbling terra cotta liner in the adjacent property’s flue, which was backdrafting through a cracked firebox into the client’s living space. We isolated the affected flue, installed a DuraFlex liner, and capped the unused damper. The odor was gone, and the carbon monoxide risk was eliminated. If you suspect you’re dealing with this, call (762) 356-6423 and we’ll investigate. This is not a hypothetical risk in Druid Hills – it’s a real failure mode we’ve seen on multiple streets.
