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 Crosby’s Preferred Gas Fireplace Repair Company
Crosby homes are different from Houston high-rises or Kingwood townhouses. We know the housing stock here: ranch-style homes off Kennsington Road, country properties on acreage along Ramsey Road, subdivisions built in the 1980s and 1990s around Newport. We also know what Harvey did to this town. We’ve seen homeowners replace roofs and siding after 2017 while chimney flashing got resealed with roofing tar, not proper counter-flashing, and that channels the next Gulf downpour straight into the firebox. Our Gas Fireplace Repair team documents every repair with camera evidence so you see exactly what we see.
When we schedule a Crosby job, you aren’t waiting on a truck from across the metro with no idea who shows up. You get the technician’s name and photo before arrival. That technician wears a uniform, carries a photo ID badge, and has passed a background check and identity verification under the Threshold Standard, the same vetting process applied across the Threshold Group family since 2002. Ruben Castellano, who leads our team, built this company on a simple idea: homeowners should never open the door to a stranger. We show you who’s coming first. Every single time.
Our Gas Fireplace Repair Services in Crosby
Gas Fireplace Repair
We repair gas fireplaces throughout Crosby, from simple pilot assembly replacements to full gas valve diagnostics on units that have sat unused for years. Because Crosby winters are mild and fireplaces are lit only a handful of times a season, components corrode from disuse more than from overwork. We test gas pressure, inspect thermocouples and thermopiles, check for carbon monoxide leakage at the seams, and replace anything that fails. Written price before work starts. Always.

Level 2 Chimney Inspection With Camera Evidence
A Level 2 inspection is the only way to see what’s actually happening inside the flue above your firebox, and in Crosby it’s essential. We snake a camera from the firebox up through the chimney chase to check for blockages, cracked clay tiles, rusted metal flue panels, and water intrusion. You don’t get a vague verbal summary. You get the camera video and still photos. Nothing we recommend happens without you seeing the evidence yourself, frame by frame.

Chimney Cap and Chimney Crown Repair
Crosby’s post-Harvey rebuilds left a lot of chimney caps and crowns in rough shape. A cracked crown or missing cap lets rain pour down the flue into your gas fireplace, rusting the firebox and soaking the surrounding framing every time a Gulf storm rolls through. We repair crowns with proper mortar, install caps sized for your flue, and replace flashing with real counter-flashing, not the roofing tar patch jobs that followed Harvey. This is the single most common repair we make for Crosby gas fireplace owners.

Gas Log Set and Burner Maintenance
Factory-built gas inserts from the late 1970s through the 1990s dominate Crosby’s housing stock, and most still have the original gas log sets. Burner ports clog with dust, spider webs, and rust flakes, producing uneven flames and soot buildup on the glass. We pull the logs, clean the burner, verify correct ember placement, and test the pilot assembly. If your flames are yellow and lazy instead of blue and crisp, something’s wrong, and we’ll find it.

Trusted Brands We Service in Crosby
We work with the gas fireplace brands that show up in Crosby homes most often, including Famco and Copperfield gas venting components and DuraFlex flue liner systems. These are the materials chimney professionals specify, not box-store substitutes. For common repairs on factory-built inserts, we keep standard gaskets, pilot assemblies, and thermocouples stocked on our trucks, which means fewer return trips to the Houston parts warehouse and faster turnaround for Crosby customers. When your fireplace is your only heat during a cold snap, you don’t want to wait a week for a gasket.
Common Gas Fireplace Repair Problems We See in Crosby Homes
- Water-damaged fireboxes from failed flashing. Post-Harvey roofing tar around chimney flashing fails in exactly the wrong way: it peels, cracks, and lets the next heavy rain run straight into the firebox and surrounding framing. We repair the flashing properly and replace rusted panels before the fireplace becomes a safety problem.
- Rusted panels and failed gaskets hidden behind clean glass. A 30-year-old factory-built insert can look fine from the front while the refractory panels behind it are falling apart and the door gasket is letting combustion gases seep into the room. A standard sweep never sees this. A Level 2 camera inspection does.
- Animal nesting in idle flues. Crosby’s mild winters and high-humidity subtropical climate mean chimneys sit unused for months at a stretch, which is a standing invitation for birds and raccoons. We remove nesting material, check for hidden damage, and install caps that keep animals out for good.
- Pilot assemblies corroded by Gulf humidity. Standing humidity in an unused gas fireplace corrodes thermocouples, thermopiles, and pilot tubing far faster than in drier climates. If your pilot lights but won’t stay lit, or the main burner won’t kick on, corrosion is usually the culprit, and it’s a straightforward fix once diagnosed.

FAQs – Gas Fireplace Repair in Crosby
Rainwater is getting into the flue and soaking the accumulated ash and creosote on the firebox floor, which produces that damp, ashy smell. The most likely culprits in Crosby are a cracked chimney crown, damaged cap, or post-Harvey flashing that was resealed with roofing tar instead of proper counter-flashing. When we diagnose it, we show you exactly where the water is entering using a camera inspection. Then we fix it at the source. Call (336) 863-3889 for a free estimate.
The short answer is yes, because a standard brush sweep never touches the inside of your factory-built unit. What it can’t see are deteriorated refractory panels, rusted seams behind the glass, failed gaskets, and combustion-gas leakage at the chase top. We regularly inspect late-1970s through 1990s factory-built inserts in Crosby and find hidden rust and panel failure that a sweep alone would miss. We show you the camera video and you decide.
Yes, and in Crosby it’s one of the most common causes we see. A cracked crown or missing cap lets rain run down the flue, where it pools in the firebox, rusts the metal components, and eventually soaks the framing around the fireplace chase. Post-Harvey, many Crosby homes had roofs replaced but chimney crowns left untouched, so the problem has been compounding for years. Repairs here are straightforward once we see the damage; call (336) 863-3889 for a free estimate.
Because in Crosby’s high-humidity subtropical climate, an idle fireplace accumulates standing moisture, mold in the flue liner, and animal nesting material far faster than in drier regions. Then when a cold snap hits and you finally light it, the first burn often ignites through debris and moisture you didn’t know was there. That’s why we recommend a Level 2 camera inspection every few years even if you barely use the fireplace. It catches the problems while they’re cheap to fix, before they become expensive or dangerous.
Because we never recommend a repair unless we show you the evidence. Every diagnostic includes camera images you can see with your own eyes, and we document every frame. If the problem can safely wait, we tell you that, in writing. If we say a panel is rusted through, you’ll see the rust on the video. That standard applies to every Crosby home we visit, and it’s why we put a written guarantee on every repair, and if the repair fails, the second visit is free. Call (336) 863-3889 and ask us directly.
On a call off Kennington Road in the Newport subdivision, a homeowner with a 1990s factory-built gas unit serviced through the summer by raccoons asked us to look at a firebox that smelled like wet ash all year. A Level 2 inspection camera showed standing water pooled at the firebox floor and rusted panel seams behind the refractory, so we documented every frame for the homeowner, then replaced the failed gasket, removed the nesting material, and resealed the crown and cap where water was wicking in around the old flashing. After drying the firebox and testing the draft, the unit lit clean and the moisture smell was gone. That’s the kind of verification we bring to every Crosby fireplace, and it’s the standard Ruben Castellano expects every technician to meet.
