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 Kirby
If your gas fireplace in Kirby won’t light, smells like cold ash when it’s off, or makes a clicking sound that never catches, the problem is usually one of three things: a failed thermopile or thermocouple, a clogged burner, or a venting issue in a chimney that was never designed for a gas appliance in the first place. Most Kirby repairs run $185 to $420 for standard parts and labor, and we can typically have a background-checked technician at your door within 48 hours. Call (336) 863-3889 and you’ll speak to a live person, not a recording.
Alcott Chimney Sweep has been repairing gas fireplaces in South Texas since 2002. Our techs know Kirby’s housing stock specifically because it’s what we see every week: brick ranches from the late 1940s through the 1970s, many of them with original masonry chimneys that have spent 50 to 70 years absorbing San Antonio’s humidity and clay soil movement. If you’re in Kirby, we’re already familiar with your street, your firebox configuration, and the exact failure patterns common to your era of home. That local knowledge means faster diagnosis and no guesswork pricing.
Why Alcott Chimney Sweep Is Kirby’s Preferred Gas Fireplace Repair Company
We didn’t become Kirby’s go-to for gas fireplace repair by upselling liners and caps that homeowners don’t need. We built that trust on transparency. Here’s what that means when you call us in Kirby: you’ll know your technician’s name and see their photo before they arrive. Ruben Castellano runs our operation on a simple rule: every tech is background-checked, identity-verified, uniformed, and announced by name before the truck leaves the shop. This is the Threshold Standard, and it’s not an optional add-on. It’s how we’ve worked since 2002 as part of the Threshold Group family of home-service companies.
Kirby homeowners call us for a second opinion constantly. Usually after another company has flagged a $4,000 liner job based on a visual glance. We run a camera down the flue every single time and show you the footage on the spot. If the liner is fine, we say so. If it’s not, you’ll see the cracks yourself before anyone asks for money. That’s why our Kirby service calls tend to turn into long-term relationships. The repair is written, quoted before we start, and covered by our 365-Day Done Right Promise. If the repair fails within a year, the second visit is free. That guarantee is on paper, on every job, in Kirby and everywhere else we work.
Our Gas Fireplace Repair Services in Kirby
Gas Fireplace and Log Set Service
Most Kirby gas fireplaces are vented log sets that see heavy use for about three weeks a year and then sit dormant for eleven months. That intermittent pattern is rough on thermopiles, pilot assemblies, and burner tubes. We service gas valves, replace thermocouples and thermopiles, clean clogged burner ports, adjust flame height, and check for gas leaks at every fitting. If your Kirby gas logs light weakly, yellow out, or won’t stay lit, it’s almost always a fixable component failure, not a full replacement. We’re one of the few shops in the San Antonio area that stocks thermopiles and pilot assemblies for older sets on the truck, which means most Kirby repairs are done in a single visit.
Level 2 Camera Inspection for Unlined and Clay-Tile Flues
If your Kirby home was built before 1980, the original chimney was almost certainly built with clay tile, and it was not designed to vent a gas appliance. Gas exhaust is cooler than wood smoke. It has more moisture in it. Over years of gas fireplace use, that moisture condenses inside the clay tile and accelerates spalling, hairline cracking, and mortar erosion. A Level 2 camera inspection is the only way to see what’s actually going on inside that flue. We run a camera from the firebox to the chimney top, record the footage, and show you every crack, gap, and obstruction in real time. We don’t recommend a liner without this footage, and we don’t expect you to authorize one based on our word alone. In Kirby, where underused masonry chimneys have quietly deteriorated for decades, a camera inspection before you use the fireplace is the single smartest move you can make.
Chimney Cap and Damper Replacement
Missing, rusted, or improperly fitted caps are a chronic problem in Kirby’s older homes. The original caps on 1950s and 1960s brick chimneys have often corroded away entirely, leaving the flue open to rain, soot, and wildlife. Then there’s the damper: if your damper won’t close, your gas fireplace is pulling a draft from inside the flue every single day, even in summer. That’s the cold-room smell Kirby homeowners describe as “the fireplace odor” when the gas isn’t even on. We install professional-grade caps from Olympia Chimney and Famco, sized to your exact flue dimensions, and we replace rusted, seized, or missing dampers with top-sealing dampers that actually stop the air exchange. If you hear birds inside the chimney in spring, the cap is the fix that stops it for good.
Firebox Panels, Logs, and Accessories
Over time, firebox panels crack from heat cycling, logs fade and degrade, and gas valves wear out. We carry or can quickly source replacement panels, log sets, and control valves matched to your specific fireplace model. We also stock professional trade materials from Copperfield and DuraFlex, the same brands chimney professionals specify, never box-store substitutes. If your Kirby fireplace needs parts, we’ll tell you exactly what they cost before ordering anything. No refundable deposits, no surprise line items.

Trusted Brands We Service in Kirby
We service and install gas fireplaces and venting components from the brands we’ve trusted for over two decades: Olympia Chimney, Famco, Copperfield, and DuraFlex. These aren’t generic parts off a warehouse shelf. Famco caps and dampers are built for Texas heat and humidity, and Copperfield’s gas venting products are specified by fireplace manufacturers for a reason. When we install a DuraFlex liner in a Kirby fireplace, we’re not adapting a universal part to your specific chimney. We’re installing exactly what your chimney needs, cut and fitted on site. We keep common replacement parts and service components on the truck for most Kirby calls, which is why our single-visit completion rate in Kirby stays high. Fast turnaround matters when your fireplace is your only heat source during a February cold snap.
Common Gas Fireplace Repair Problems We See in Kirby Homes
Kirby’s older housing stock, damp soil, and limited seasonal use create a specific pattern of gas fireplace failures. These are the ones we see most often on Kirby service calls:
- Gas log sets venting into unlined or clay-tile flues: Most Kirby gas fireplaces from the 1950s through the 1970s were installed into chimneys built for wood, with no stainless liner. Gas exhaust condenses inside the clay tile, slowly eating away the mortar and creating carbon monoxide pathways you cannot see without a camera. This is the top repair and retrofit job we do in Kirby.
- Rusted or seized dampers that won’t close: Decades of humidity and occasional rain intrusion into uncapped flues wreck dampers fast. A damper stuck open is why your Kirby house feels cold in December and why the fireplace smells like ash even in July. Replacement usually runs $180 to $340.
- Chimney swift nesting between April and October: Kirby sits in the heart of the chimney swift migration corridor, and uncapped masonry flues are prime nesting spots for these federally protected birds. If we arrive for a cleaning or repair during nesting season and find active nests, we legally cannot proceed until the birds fledge. We’ll schedule your follow-up for the exact date the nest should be clear and come back then.
- Hairline firebox cracks and spalling brick from freeze-thaw cycles: Kirby’s rare hard freezes, like February 2021 when temps dropped into the 20s, stress bricks that have spent decades absorbing moisture from clay soil and humidity. Cracks inside the firebox can let heat reach combustible framing, and spalling on the exterior is a sign the structure is weakening from the inside out.

FAQs – Gas Fireplace Repair in Kirby
A sealed fireplace should not smell when it’s off. That cold, ashy smell in your Kirby home means the flue is open to the outdoors, and air is back-drafting through the chimney into your living space. The usual culprits are a damper stuck open, a missing or damaged chimney cap, or a cracked flue liner that’s pulling air from inside the wall cavity. In Kirby’s older brick-veneer homes, we most often find a rusted damper plus a deteriorated clay-tile liner working together. The fix starts with a camera inspection so you can see the path the air is taking, then we replace what’s actually failed. Call (336) 863-3889 and we’ll schedule a Kirby service call.
Usually yes, but between April and October we may first need to check for chimney swifts, which are federally protected under the Migratory Bird Treaty Act. Kirby’s location inside the San Antonio corridor means swifts commonly nest in uncapped masonry flues every spring and summer. If we find an active nest, we are legally required to pause the work until the birds fledge, which usually takes four to six weeks from the time eggs are laid. We’ll document the nest, schedule your return for the expected fledge date, and handle the repair or cleaning then. If your flue is capped, this rarely comes up.
Expect us to go slow and show you everything. A 1960s-era Kirby chimney was built for wood, not gas, and it has spent 55 to 60 years in San Antonio’s humid, clay-soil environment. We’ll start with a visual check of the firebox, damper, and exterior brick, then run a Level 2 camera inspection through the entire flue. You’ll see the footage yourself, including any cracked tiles, missing mortar, or animal debris. Then we’ll give you a written quote for what actually needs work, if anything. Many of these older Kirby chimneys are still structurally fine with a good cleaning and a damper repair, but you will not know until the camera goes in.
Once a year, and the reason is exactly because it sits idle most of the time. Kirby sees fewer than 30 meaningful heating days annually, which means your fireplace spends 11 months collecting moisture, dust, and sometimes animal nesting debris in the flue. Then you fire it up cold on the first 35-degree night, and any buildup, obstruction, or hidden crack becomes a real hazard in seconds. An annual service call in Kirby, around $150 to $200 for a standard inspection and light cleaning, is far cheaper than a liner replacement or a firebox rebuild after a chimney fire. If you went two or more years without checking, call (336) 863-3889 to schedule a camera inspection before the next cold snap.
It’s real, and here’s the mechanism: Kirby sits on expansive clay soil that swells when wet and shrinks when dry. That movement, repeated over decades, puts stress on slab foundations and the masonry chimneys attached to them. The result is hairline cracks in mortar joints, shifting flue tiles, and small separations where the chimney meets the roofline. We’re not talking about dramatic structural failure in most cases. We’re talking about the slow accumulation of gaps that let heat, gas, and moisture move where they shouldn’t. If a company tells you that clay soil means you need a $6,000 rebuild without showing you camera footage of the damage, hang up. If we see soil-related cracking in your Kirby chimney, we’ll show you the cracks on camera and tell you honestly whether they’re a current hazard or something to monitor.
