Why Alcott Chimney Marietta Is Marietta’s Preferred Gas Fireplace Repair Company
Ruben Castellano built Alcott Chimney Sweep on a simple idea: you should know exactly who’s coming to your house before they ring the bell. Every technician we send to a Marietta home is background-checked, identity-verified, and introduced to you by name and photo before arrival. That’s the Threshold Standard, and it’s not optional. When our tech shows up at your door near Kennesaw Mountain or off Powder Springs Road, they’ll be wearing a uniform and carrying a photo ID badge you can check against the picture we sent.
We’ve been part of the Threshold Group family since 2002, and the way we handle gas fireplace work in Marietta hasn’t changed: written price before any work starts, written guarantee on every repair, and a live person answering the phone around the clock. If your fireplace smells like something’s burning at 11 p.m., you won’t get a voicemail. You’ll get a human being.
Marietta homeowners deal with a specific set of gas fireplace problems, and we’ve seen all of them. Historic homes around the Square with original brick chimneys. Ranch houses from the 60s and 70s with unlined flues that were never meant for a gas insert. Split-levels in East Cobb where the chimney cap rusted out years ago and nobody noticed until the burner started failing. Knowing these houses means we can often diagnose the problem over the phone and bring the right parts on the first trip.

Our Gas Fireplace Repair Services in Marietta
Flue Liner Inspection and Repair
Many gas fireplaces in Marietta are vented through chimneys that were built for wood fires decades ago. If that chimney has an unlined flue or a cracked clay liner, gas exhaust doesn’t draft properly, and that’s a carbon monoxide risk. We inspect liners with a camera, show you the footage, and only recommend a repair if we can show you the crack on screen. For historic homes near the Square where preserving the original brick matters, we install DuraFlex liners that fit inside the existing flue without tearing out masonry.
Chimney Cap Replacement
Missing or rusted chimney caps are one of the most common calls we get from Marietta homeowners. The tree canopy around neighborhoods like Whitlock Heights and Maple Avenue means leaves, twigs, and the occasional squirrel find their way into open flues. A proper cap keeps out debris and rain, and we carry Olympia Chimney and Famco caps in common Marietta sizes for faster turnaround. Replacing a cap before it fails means you avoid water damage to your gas logs and burner assembly.
Damper Repair and Replacement
Gas fireplaces still need a functioning damper, even if you never burn wood. A warped or seized damper lets conditioned air escape in summer and can trap exhaust in winter. We see damper problems most often in Marietta’s older homes, where years of humid air have swollen or corroded the original hardware. We repair what’s salvageable and replace what isn’t, always with a written price before we start.
Gas Log and Burner Service
Sooty glass, weak flames, or a burner that won’t stay lit usually points to a draft problem, not a bad gas valve. In Marietta, that draft problem is often a blocked flue, a cracked liner, or a damper that’s stuck half open. We clean the burner and logs, check the gas pressure, and verify the venting is moving exhaust out of your house the way it should. Our Gas Fireplace Repair team carries professional brands like HeatShield and Gelco, so the materials we install are the same ones chimney professionals specify.

Common Gas Fireplace Repair Problems We See in Marietta Homes
- Sooting and black glass: When a cracked flue liner or blocked cap starves the fire of draft, gas logs burn dirty and deposit soot on the glass and surrounding brick. We find this constantly in Marietta homes with original chimneys that have never been lined.
- Rust on burners and log sets: Water intrusion through worn flashing or a cracked crown drips down onto gas components and corrodes them. Marietta’s heavy spring rains make this failure mode especially common here.
- Fireplace won’t light or stay lit: Bird and squirrel nests from the surrounding tree canopy block the flue, or a damaged damper assembly prevents proper exhaust flow. The safety sensors shut the unit down, which is frustrating but working as intended.
- Musty smell in summer: Humid Southern air settles in the firebox and chimney during warm months, especially in older homes near the Square where chimneys lack modern dampers. A sealed damper or a top-mount damper fixes this.

FAQs – Gas Fireplace Repair in Marietta
Every year, even if you only use the fireplace occasionally. Marietta’s humid climate accelerates mortar deterioration, and an annual inspection catches spalling brick, blocked flues, and rust before they become expensive repairs or safety hazards. Call (229) 350-8952 to schedule your inspection.
Soot on gas logs and glass usually means the flue isn’t drafting properly, often because a cracked liner or blocked cap is restricting airflow. In older Marietta homes with unlined chimneys, this problem appears within weeks of first use. We diagnose the draft issue with a camera inspection and fix the root cause, not just the symptom.
Yes. Unlined chimneys in Marietta’s historic district are common, and they can’t safely vent a gas fireplace without a modern liner. We install DuraFlex stainless liners inside the existing chimney structure, which preserves the original brick exterior while giving you a properly sized, code-compliant flue. The work is done from the top or through the firebox, so your living room walls stay intact.
A Level 2 inspection is a camera-based evaluation of the entire flue interior, the smoke chamber, and accessible portions of the exterior. You need one whenever you’re relining a chimney, buying a new gas insert, or after a known event like a chimney fire or major storm. In Marietta, we recommend a Level 2 inspection before any liner work on a historic home, because the original flue often has hidden gaps or blockages you can’t see from the firebox. The inspection typically runs $250 – $450.
Marietta’s humid summer air settles inside the chimney and firebox, and when your AC pulls air through the house, that damp smell comes right into the living space. The fix is usually a properly sealed damper or a top-mount damper that blocks the flue entirely when the fireplace isn’t in use. It’s a straightforward repair, and you’ll notice the difference within a day or two.
Marietta’s Old Chimneys Need a Different Kind of Repair
If you own a home built before 1950 in Marietta, your chimney wasn’t designed for what it’s doing now. The original brick was laid for wood fires, often without a clay liner, and a gas fireplace vents differently: lower temperatures, more water vapor, and acidic condensation that eats away at old mortar. Add in Marietta’s humid subtropical climate, and you get spalling brick and efflorescence, that white chalky residue that signals water moving through the masonry. Before anyone can safely reline a flue on one of these houses, the damaged brick and mortar have to be addressed first. We handle that entire scope, from masonry repair to liner installation, so you’re not coordinating between two different companies.
At a 1920s bungalow near the Marietta Square, our tech found a gas fireplace with a warped damper and a smoke chamber so deteriorated that the original brick had crumbled from decades of humid air. We rebuilt the smoke chamber, installed a new damper, and ran a Level 2 inspection to confirm the flue was safe for continuous gas use. That’s the kind of work Marietta’s older homes need, and it’s the work we do most often.
If you live in Marietta and your gas fireplace is acting up, whether it’s sooting, rust, a musty smell, or a unit that won’t stay lit, call Ruben Castellano’s team at Alcott Chimney Marietta. We’ll send a background-checked, identity-verified technician whose name and photo you’ll have before we arrive. You’ll get a written price before any work starts, and a written guarantee on every repair. Call (229) 350-8952 for a free estimate.
