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.

Ruben Castellano has built Alcott Chimney Sweep around a simple idea: you should know exactly who’s walking through your door and exactly what they’re going to charge before the truck ever leaves the shop. That’s how we’ve operated since 2002, and it’s why Fort Worth homeowners keep our number saved for the first cold snap of the year.
Why Alcott Chimney Sweep Is Fort Worth’s Preferred Gas Fireplace Repair Company
Most chimney companies send a technician you’ve never heard of, in a truck you can’t verify, with a quote that changes after the work starts. We don’t. Every Alcott technician in Fort Worth is background-checked, identity-verified, and announced to you by name and photo before arrival. When the doorbell rings, the person standing there matches the photo you already have, and they’ll show you a photo ID badge at the door. That’s the Threshold Standard, and it’s been our rule since day one. Ruben Castellano put it in place because he knows what it’s like to open your door to a stranger. You shouldn’t have to wonder.
Fort Worth has a housing stock that demands real local knowledge. The historic bungalows in Fairmount and Ryan Place were built for wood fires, not gas log sets. The prefab units in Wedgwood and Ridglea tract homes are now decades past their expected service life. We know these houses because we work on them every week. You won’t have to explain your street layout, your roof pitch, or why your chimney is shared with the house next door. We already know.
Every job comes with a written price before any work starts, and a written guarantee on every repair. If a repair fails within the coverage period, the second visit is free. That’s the 365-Day Done Right Promise: a full year of accountability on every completed job in Fort Worth.
Our Gas Fireplace Repair Services in Fort Worth
Gas Log Set Inspection and Recommissioning
Before the first fire of the season, your gas log set needs more than a visual once-over. We check the gas valve, thermocouple, pilot assembly, burner ports, and the flue the set vents into. In Fort Worth’s older homes, that flue is often the weak link. A gas log set burning in a 1920s unlined clay-tile flue isn’t just inefficient; it’s moving combustion byproducts through a passage that’s spalling and cracking in ways you can’t see from the living room. We inspect the full vent path, and we show you the camera footage. Recommissioning includes testing the millivolt system, checking for gas leaks at the supply fitting, and verifying draft with the damper in the correct position for a vented log set.
Shared-Flue Cross-Contamination Testing
This is the service that matters most in Fort Worth’s dense historic districts. In Fairmount and parts of Ryan Place, attached bungalows often share a single masonry stack. That means your flue and your neighbor’s flue are separated by a few inches of old mortar. When that mortar erodes or a flue liner cracks, exhaust from your neighbor’s gas furnace or fireplace can push into your flue, and vice versa. We test for this with a smoke and pressure differential check, then confirm with a camera. If cross-contamination is present, it’s a carbon monoxide issue, not just a smell problem, and it needs to be sealed properly.
Flue Liner and HeatShield Installation for Converted Gas Appliances
Fort Worth’s Fairmount and Ryan Place historic districts contain dense concentrations of 1920s to 1940s Craftsman bungalows and Colonial Revival homes. Many of these were converted from wood to gas decades ago, and a number of those conversions left the original clay-tile flue in place. Gas combustion produces acidic water vapor that eats away at old clay tile and mortar far faster than wood smoke does. By the time we’re called, a spalled flue is a near-standard finding. We install HeatShield flue liners that are sized specifically for gas appliance output, restoring a continuous, sealed vent path without tearing apart your masonry. We also carry and install DuraFlex liner systems where the stack configuration calls for a flexible solution.
Prefab Fireplace Repairs in Wedgwood and Ridglea
Wedgwood, Ridglea, and the postwar tract neighborhoods of Fort Worth are full of zero-clearance prefab fireplace units from the 1950s through 1970s. Refractory panels crack, door gaskets flatten and leak, and millivolt gas valves fail. The question is rarely whether the unit has a problem; it’s whether the problem is repairable. We give you an honest answer, backed by a camera inspection and a written quote before work starts. Some prefab units are worth repairing. Some aren’t. We’ll tell you which one you have, and we’ll put it in writing.

Common Gas Fireplace Repair Problems We See in Fort Worth Homes
- Gas log sets venting into original unlined clay-tile flues. In Fairmount and Ryan Place, it’s the single most common finding. The acidic exhaust erodes spalling mortar and crown cracks, and the flue steadily becomes less capable of moving combustion gases up and out of your house.
- A neighbor’s appliance back-drafting into a shared masonry stack. In dense bungalow rows where homes share a chimney stack, a failing flue liner in one home can push exhaust, including carbon monoxide, into an adjacent flue. The odor is often faint and intermittent, and homeowners frequently mistake it for a dead animal or fireplace odor.
- Freeze-thaw crown and mortar damage from abnormal cold events. Fort Worth’s February 2021 freeze subjected masonry chimneys to thermal cycling far beyond what North Texas masonry is built for. Cracks that started then are still widening every winter, letting rain into the smoke chamber and damper assembly.
- Refractory panel and gasket failure in decades-old prefab units. Wedgwood, Ridglea, and eastside tract neighborhoods are full of 1960s prefab fireplaces at the end of their serviceable life. Cracked refractory panels expose the metal firebox to direct flame, and worn door gaskets leak combustion gases into the room.

FAQs – Gas Fireplace Repair in Fort Worth
You’re likely experiencing cross-contamination in a shared masonry stack. If your Fairmount or Ryan Place bungalow shares a chimney with the house next door, a deteriorated flue liner or crumbling mortar crown can allow exhaust from your neighbor’s fireplace or furnace to push into your flue. The smell is often intermittent, appearing only when the neighbor uses their appliance. This is not a nuisance issue; it’s a carbon monoxide pathway and needs to be tested and sealed. Call (336) 863-3889 and we’ll test both flues with a camera and pressure differential equipment.
Not necessarily safe, and we find this configuration constantly in Fort Worth’s historic districts. Original clay-tile flues from the 1920s were built for wood smoke, not the acidic water vapor produced by gas combustion. By now, most of those liners are spalled, cracked, or partially collapsed. The gas log set may look fine from the living room while combustion byproducts leak through deteriorated mortar joints into wall cavities or adjacent rooms. The correct fix is a properly sized flue liner, typically HeatShield or DuraFlex, installed after a camera inspection documents the exact condition of your flue. Call for an inspection and a written quote, and we’ll show you everything on camera before you spend a dollar.
Fort Worth’s rare but extreme winter events, most infamously the February 2021 freeze, subject masonry chimneys to severe freeze-thaw thermal cycling that is abnormal for North Texas. Water enters small pores in the mortar crown, freezes and expands during those brutal cold snaps, and then thaws. The cycle repeats and cracks widen. Even in a mild winter, the damage from a past hard freeze keeps working. The long, intensely hot Fort Worth summers also bake any residual creosote into a glass-hard stage-3 glaze, meaning the first fire of the season after a hot summer is the most dangerous one you’ll light all year. A camera inspection shows exactly what your crown and flue look like right now.
Yes, and in some ways gas-only fireplaces in Fort Worth need inspections more urgently than wood-burning ones. Gas combustion produces water vapor that aggressively attacks clay tile and mortar, and because you don’t see smoke or sparks, problems develop invisibly. A vented gas log set still requires a fully functional flue to carry combustion gases outside. A Level 2 camera inspection every one to two years is the right cadence for a vented gas appliance, and it’s the only way to catch flue deterioration or cross-contamination before it becomes a carbon monoxide event. Our inspections start at $149 and are credited toward any needed repair.
Usually it’s a repair. The most common cause in Wedgwood and Ridglea prefab units is a failing thermocouple or thermopile, which runs $165 to $320 to replace. A pilot that lights but won’t hold is a classic millivolt system issue, and it’s one of the most straightforward gas fireplace repairs we do in Fort Worth. If the refractory panels are cracked or the gas valve itself has failed, you’re looking at a more expensive decision, and sometimes replacement is genuinely the better call. We’ll show you the camera evidence and the written repair quote so you can decide with real information, not a salesman’s pitch. Call (336) 863-3889 for a free estimate.
