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.

Why Alcott Chimney Sweep Is Somerset’s Preferred Gas Fireplace Repair Company
What we hear most from Somerset homeowners is that they want to know exactly who’s walking up their driveway. That’s fair. Ruben Castellano built Alcott Chimney Sweep on a simple promise: the technician whose name and photo you receive before the visit is the same person who shows up, uniformed, background-checked, and holding a photo ID badge at your door. That’s the Threshold Standard, and it applies to every single job we do in Somerset. No exceptions, no “the regular guy couldn’t make it.”
We’re part of the Threshold Group family of home-service companies, which has served homeowners since 2002. Every repair we complete in Somerset comes with a written price before work starts and a written guarantee when the work is done. If a repair fails within the coverage period, the second visit is free. That’s the 365-Day Done Right Promise, and it applies whether we’re replacing a thermocouple on a gas log set off Old Somerset Road or rebuilding a smoke chamber on a farmhouse off SH 1604.
Our crews respond to Somerset regularly from the San Antonio metro office, so scheduling is straightforward and we’re familiar with the local housing stock. We know which neighborhoods have 1970s brick ranch chimneys with clay-tile flues, which farmhouse properties have never had a cap replaced, and which gas fireplaces were retrofitted into fireboxes that originally burned wood. That local knowledge means we arrive already knowing what to look for.
Our Gas Fireplace Repair Services in Somerset
Gas Fireplace Diagnostic and Camera Inspection
This is where every Somerset repair should start. We scope the flue and firebox with a camera before recommending anything. In Somerset specifically, gas logs vented into masonry chimneys built from the 1950s through 1980s often hide cracked smoke chamber mortar behind the damper, where nobody can see it without a scope. Our camera inspection produces footage you watch with us on the monitor, so when we say a repair is needed, you see it with your own eyes. A diagnostic visit in Somerset usually runs $150 – $250.

Smoke Chamber and Damper Repair
Smoke chambers on older Somerset ranch chimneys take a beating from the region’s expansive clay soil. The ground shifts, the masonry stack moves with it, and mortar joints crack. That lets heat and gases press into spaces they were never meant to reach. We repair spalled and cracked smoke chamber mortar using professional trade materials, and we rebuild dampers that no longer seat properly. Expect $400 – $900 for typical smoke chamber work in Somerset, depending on access and extent.

Chimney Cap and Crown Replacement
Somerset’s rural properties sit idle much of the year, and idle chimneys without working caps become wildlife housing. Raccoons, chimney swifts, and squirrels find their way into flues with missing or rusted-through caps. We install new caps from brands like Copperfield and Famco, and we rebuild crown surfaces that have cracked from clay-soil movement. Crown and cap work typically runs $350 – $750 in Somerset.

Gas Log Set Repair and Replacement
If your Somerset gas fireplace won’t stay lit, the problem is often a worn thermocouple or thermopile, a dirty pilot assembly, or a failing gas valve. We service and replace log sets across Somerset, and we always verify the venting before we declare the firebox fixed. A repair on an existing log set typically runs $200 – $450, while a full replacement depends on the set you choose. We’ll give you the written price before any work begins.

Trusted Brands We Service in Somerset
We install and service gas fireplaces and venting from names the trade actually specifies: Famco, Copperfield, DuraFlex, and HeatShield. When a Somerset homeowner needs a liner repair or cap replacement, we bring these brands, not whatever was on sale at the hardware store. We keep common parts stocked for faster turnaround on repairs across the 78069 zip code, so a straightforward gas valve or thermocouple replacement often doesn’t require a second trip.
Common Gas Fireplace Repair Problems We See in Somerset Homes
- Gas logs vented into unlined clay-tile flues they were never designed for. Many Somerset homes built between the 1950s and 1980s originally burned wood, and later owners dropped gas log sets into fireboxes that still vent through the original clay-tile stack. This setup is legal but demands more careful inspection, because tile deterioration inside the flue is invisible without a camera.
- Chimney swifts blocking summer repair work. Chimney swifts are a federally protected migratory bird, and they love idle Somerset chimneys in late spring and summer. If they’re roosting in your flue, we legally cannot perform the work until they vacate in fall. Our technicians flag this before you schedule a summer repair.
- Rusted-through chimney caps on idle rural properties. Somerset fireplaces light maybe 3 – 5 times a year, so caps rust out without anyone noticing. That’s how raccoons and nesting material end up sitting against the damper, creating a fire hazard the first cold night you light the logs.
- Clay-soil crown cracks that mimic gas-valve problems. Houston Black clay expands and contracts with moisture, and Somerset chimneys shift with it. The crown cracks, water gets in, mortar spalls, and the fireplace drafts poorly. Homeowners sometimes think the gas valve is bad when the chimney structure is the real issue.

FAQs – Gas Fireplace Repair in Somerset
A cleaning has nothing to do with gas valve function, so a clean chimney doesn’t mean a healthy fireplace. In Somerset’s older ranch homes, the most common reasons a gas fireplace won’t stay lit are a worn thermocouple, a dirty pilot assembly, or a gas valve that’s failing. But before we replace any part, we scope the flue, because cracked smoke chamber mortar behind the damper can also cause draft problems that make the pilot behave erratically. Call (336) 863-3889 and we’ll diagnose it properly.
No, and that’s not a company policy, it’s federal law. Chimney swifts are protected under the Migratory Bird Treaty Act, and once they’re roosting in a Somerset chimney, we cannot legally perform repair or cleaning work until the birds vacate in fall. What we can do is schedule the visit, note the issue, and get your repair on the calendar for the first available date after they leave. Call us and we’ll explain exactly how the timing works.
Yes, and it’s one of the most overlooked causes of gas fireplace problems in this area. Somerset sits on expansive Houston Black clay that swells when wet and shrinks when dry. That seasonal movement shifts masonry chimney stacks, cracking crowns, flashing, and smoke chamber mortar. The result is poor draft, moisture intrusion, and spalling that has nothing to do with how often you use the fireplace. We check for structural clay-soil damage on every Somerset inspection.
Annually, even if you only light it three or four times. The low usage is exactly why problems go unnoticed in Somerset. Critters move in, caps rust through, and clay-soil movement works on the masonry all year whether you burn or not. An annual inspection catches the cap that’s about to fail before a cold January night turns it into a fire hazard. Most Somerset annual inspections with camera scoping run $150 – $250.
Not unless camera footage shows the existing liner has failed. On a ranch property off Old Somerset Road, our technician scoped a gas log set vented into an unlined clay-tile flue and found spalling smoke chamber mortar with a rusted-through cap letting raccoon nesting material sit against the damper. We showed the homeowner the footage, rebuilt the crown, and installed a new cap, but we did not sell a liner because the tiles were still sound. If your flue is genuinely compromised, we’ll show you on the monitor. If it’s not, we’ll say so plainly.
