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.

Our Gas Fireplace Repair Services in Southlake
Most gas fireplace problems in Southlake fall into a few clear categories. Here’s how we approach each one.
Gas Fireplace and Gas Log Set Inspection with Camera Evidence
Southlake has a high number of gas log sets retrofitted into fireplaces that were originally built for wood. That’s not automatically a problem, but it often means the flue behind the wall was never sized for a gas appliance. We run a camera up the flue and show you exactly what’s there. If the clay tile liner is undersized, cracked, or missing sections, you’ll see it on our screen before we recommend anything. No recommendations without camera evidence. That’s the rule.
Chimney Crown and Cap Evaluation and Repair
Southlake chimneys sit idle most of the year, so a cracked crown or a rusted chase cover can leak for two or three seasons before anyone notices. By the time water reaches your ceiling or dampens the firebox, the damage is already done. We inspect crowns and caps on every gas fireplace visit, and we document what we find with photos. If a repair will hold, we repair it. If it won’t, we’ll tell you why and show you the evidence.
Mortar Joint Repointing on Settling Masonry Chimneys
The expansive clay soils under Tarrant County move as they wet and dry. In established Southlake neighborhoods like Timarron, where large masonry chimneys have been settling since the mid-1990s, we regularly see stepped mortar joint cracking along the north or west faces. This is a soil heave signature, not a fireplace problem. Until those joints are repointed, any cap or crown repair will fail. Our crews repoint with materials specified for North Texas masonry, then seal the repair properly.
Gas Valve, Pilot, and Burner Repair
When a gas fireplace won’t light, won’t stay lit, or burns with a weak, lazy flame, the cause is usually the pilot assembly, thermopile, or gas valve. We diagnose these on-site, explain the fix in plain terms, and give you a written price before touching anything. We carry common replacement parts for major brands, which means fewer return trips and faster turnaround for Southlake homeowners.
Trusted Brands We Service in Southlake
We work on gas fireplaces and gas log sets from the major brands, and we stock or rapidly source parts from Olympia Chimney, Famco, and Copperfield. These are professional trade brands, the same ones chimney specialists specify, not box-store substitutes. For Southlake customers, that means we’re not waiting on a random online order when your gas valve fails in December. When we need a liner component, a termination cap, or a refractory panel, we pull from what we carry or order from suppliers who serve the DFW trade directly. Faster parts mean faster repairs, and that matters when the temperature drops and you actually want to use your fireplace.
Our work across Southlake includes gas log sets, direct-vent inserts, and vent-free systems, along with the chimneys and vents they’re connected to. If you’re not sure what you have, that’s a good reason to call. We’ll identify the unit, check its venting, and give you a straight answer about what it needs.
Common Gas Fireplace Repair Problems We See in Southlake Homes
- Gas logs vented into undersized clay tile flues. Many Southlake homeowners have gas log sets dropped into fireplaces originally built for wood. The original clay tile liner was sized for a wood fire’s draft, not a gas appliance’s lower heat and higher moisture. This causes poor draft, lingering exhaust smells, and accelerated liner deterioration.
- Corroded chase covers and cracked crowns that leak during the first hard freeze. Because Southlake fireplaces go months without use, water damage from a failed crown or rusted chase cover often shows up as a ceiling stain or a damp firebox before anyone suspects the chimney. By then, the repair is bigger and more expensive.
- Stepped mortar joint cracking on north and west chimney faces. In neighborhoods like Timarron, where chimneys have sat on expansive clay for 25 to 30 years, seasonal soil movement opens stair-step cracks in the mortar. It looks like a structural problem, but it’s usually repairable with proper repointing. Left alone, water works into those cracks and turns a $400 repointing job into a $3,000 rebuild.
- Weak flames and exhaust smells from a gas appliance vented into a compromised flue. A lazy yellow flame or a faint gas smell in the room is not something to ignore. It often points to a blocked or undersized flue, a failing gas valve, or a cracked refractory panel. We diagnose it on-site, with camera evidence, and only recommend what the evidence supports.

FAQs – Gas Fireplace Repair in Southlake
Not always, but often. Clay tile flues were designed for wood fire temperatures and draft patterns. A gas appliance vents cooler, moister exhaust, and if the flue is too large or has cracked tiles, that exhaust condenses inside the flue and accelerates deterioration. We camera-inspect every flue before recommending a liner, and we’ll show you the footage. If the flue is sound and sized correctly, no liner is needed. If it’s not, we’ll explain exactly what we saw. Call (336) 863-3889 to schedule an inspection.
Every year, even if you rarely use it. Inactivity is exactly what lets moisture, nesting debris, and masonry deterioration accumulate unnoticed around Southlake. Then a cold snap hits and a fireplace that sat idle for 11 months is suddenly running for hours a day. An annual inspection catches problems when they’re small and cheap to fix. If it’s been more than a year, it’s time. Estimates are free at (336) 863-3889.
That stair-step pattern is the signature of expansive clay soil movement. Tarrant County’s clay swells when wet and shrinks when dry, and over decades, that seasonal shift can open stepped cracks in the mortar on a chimney’s north or west face. It’s usually repairable with proper repointing, but it should be evaluated soon, because water getting into those joints turns a repointing job into a structural problem. Call (336) 863-3889 and we’ll take a look.
Think of first-degree creosote as fluffy soot that brushes away easily. It’s mostly a wood-burning concern. Third-degree creosote is a dense, glazed, tar-like coating that forms when flue temperatures run low and sticky. Gas fireplaces don’t produce creosote in the same way wood fires do, but if a gas log set is venting into a flue that previously carried wood smoke, old creosote deposits can remain and pose a fire risk. It also affects draft. That’s another reason we camera-inspect every flue, even on a gas-only chimney.
Stop using the fireplace and call us. A weak, lazy flame combined with an exhaust smell usually means the flue isn’t drafting properly, the gas valve is failing, or the burner is clogged or damaged. It’s not something to troubleshoot while the unit is running. Call (336) 863-3889 and describe what you’re seeing. A live person answers, day or night, and we’ll walk you through whether it’s safe to keep the gas off until we arrive.
