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 Cloverleaf
Gas fireplace repair in Cloverleaf usually costs between $160 and $550 depending on what’s actually wrong, and most jobs are done in a single visit. If your gas logs won’t light, the pilot keeps quitting, or you can smell something acrid when the fire runs, call Alcott Chimney Sweep at (336) 863-3889. We’ve worked on hundreds of Cloverleaf fireplaces, and we know what these older chimneys look like inside before we ever ring the doorbell.
Cloverleaf isn’t like the newer subdivisions west of Houston. The housing stock here dates to the 1950s and 60s, when gas fireplaces were rare and gas log retrofits were a weekend project, not a permitted installation. That means the repair questions we get in Cloverleaf are different from what we hear in San Antonio or Fort Worth. The stacks are older, the flues are often unlined, and the dampers have decades of Gulf Coast humidity baked into them. Our Gas Fireplace Repair team treats every Cloverleaf job as a camera-verified diagnosis first, a quote second, and a repair third. Nothing gets recommended that you can’t see with your own eyes on our monitor.
Why Alcott Chimney Sweep Is Cloverleaf’s Preferred Gas Fireplace Repair Company
Ruben Castellano built Alcott Chimney Sweep in 2002 around a simple frustration: homeowners kept telling him they had no idea who was going to show up, what the repair would actually cost, or whether the work was really necessary. In Cloverleaf, where many of the chimneys predate modern liner codes, that uncertainty gets exploited by companies that quote liner replacements sight unseen. We do the opposite. Every technician who knocks on a Cloverleaf door has passed a background check and identity verification under the Threshold Standard, and you’ll get their name and photo sent to you before the truck arrives. They’ll show a photo ID badge at the door. No exceptions, ever.
We also write the price down before any work starts. A written quote is standard on every job, not an upgrade. If the repair fails within the coverage window, the second visit is free under our 365-Day Done Right Promise. That’s a full year of accountability on a fireplace that might only get used four times between November and February. Cloverleaf homeowners don’t run their gas logs every night, so a repair that fails quietly in March shouldn’t surface as a surprise in December. We guarantee it won’t.
Dispatch and scheduling for Cloverleaf are coordinated from our Houston metro office, but our crews serve the area locally and know the neighborhoods well. When a call comes in from Alderson Street or the blocks around North Shore High School, we know the houses, the chimney types, and the common failure points before we arrive.
Our Gas Fireplace Repair Services in Cloverleaf
Gas Fireplace and Gas Log Set Inspection with Camera Evidence
Before we touch anything, we run a camera down the flue and show you what’s there. In Cloverleaf, that step matters more than in most places because so many fireplaces were retrofitted decades ago without any inspection at all. A camera run usually takes 20 to 30 minutes and costs between $95 and $150 as part of a service call. You watch the monitor while we explain what we’re seeing, and you get a photo report you can keep. If we find nothing wrong, you’ll hear exactly that. We don’t invent problems to justify a visit.
Flue Liner Evaluation and HeatShield Resurfacing
This is the big one for Cloverleaf. Many of the 1950s and 60s chimneys here have clay-tile flues that were never designed for vented gas log sets, and decades of intermittent use plus rare hard freezes have cracked them. HeatShield is a resurfacing system we install to restore the liner’s integrity without tearing out the original masonry. A HeatShield resurfacing job in Cloverleaf typically runs $1,800 to $3,200 depending on flue length and access. We only recommend it when the camera footage shows actual damage, and we’ll show you that footage before you decide anything.
Damper and Firebox Repair After Undocumented Retrofits
Gas log retrofits in unincorporated Harris County often included damper modifications that were never inspected. The damper gets removed, or clamped open, or bent to accommodate the gas line, and the firebox stays open to humid air year-round. That humidity accelerates mortar decay and spalling inside the smoke chamber. Repairing or replacing a damper, or rebuilding a damaged firebox panel, usually costs between $250 and $700 in Cloverleaf. We’ll quote it after we see the condition, and we’ll show you why it needs attention before you spend a dollar.
Thermocouple, Pilot Assembly, and Gas Valve Repair
Not every Cloverleaf gas fireplace problem is structural. Pilots that won’t stay lit, thermocouples that have failed, and gas valves that stick are common in older units, especially ones that sat unused through the humid summer. Replacing a thermocouple or pilot assembly in Cloverleaf typically runs $140 to $260. Gas valve replacements are more involved and run $300 to $550 including the part and labor. We replace with trade-grade components, not box-store substitutes, and every repair carries our written guarantee.

Trusted Brands We Service in Cloverleaf
We work on most major gas fireplace brands and carry professional trade materials including HeatShield, Gelco, and Olympia Chimney. When a Cloverleaf repair needs a liner, a cap, or a damper assembly, we’re not ordering generic parts that arrive in a week. We stock the brands chimney professionals specify, which means most repairs finish the same day the parts are diagnosed. We also service and install Famco components for venting and termination work. If you have an older fireplace with an obscure brand name, that’s fine too. Call us and we’ll tell you straight whether parts are still available, and what the realistic options are.
Common Gas Fireplace Repair Problems We See in Cloverleaf Homes
- Gas log sets venting into unlined 1950s – 70s clay-tile flues. The appliance was never designed for the stack it’s in, and the liner has often cracked from decades of thermal cycling. This is the most common hidden condition we find in Cloverleaf, and it requires camera verification before any repair is quoted.
- Dampers modified or removed during old retrofits. A firebox left open to Gulf Coast humidity for years accelerates mortar joint decay and spalling in the smoke chamber. Homeowners often smell dampness or see rust stains on the firebox floor and assume it’s a gas problem when it’s really a moisture problem.
- Corroded flashing and chimney crowns from Ship Channel air exposure. Cloverleaf sits downwind of the Houston Ship Channel’s petrochemical corridor, and sulfur dioxide plus industrial particulates eat at metal flashing faster here than in Houston’s western suburbs. Water tracks down into the smoke chamber and mimics gas-valve or pilot problems that are actually flue integrity issues.
- Clay-tile liners cracked by rare hard freezes. The February 2021 freeze sent thermal shock through chimneys all over Cloverleaf that had been weakened by years of humidity and disuse. Homeowners call us for a pilot that won’t stay lit, and the camera reveals a cracked flue liner that’s the real emergency.

FAQs – Gas Fireplace Repair in Cloverleaf
Yes, and it’s one you should not ignore. A sulfur or rotten-egg smell points to either an incomplete burn, a venting problem, or in some cases a gas leak. On a 1960s Cloverleaf chimney with an undocumented gas log retrofit, the most common cause is venting into a damaged or partially blocked flue, which lets combustion byproducts drift back into the room. Shut the fireplace off and call us at (336) 863-3889. We’ll camera the flue and find the source before anyone quotes a repair.
Yes, and there’s a reason. In Cloverleaf, the gas fireplace is almost never the only component that matters. The flue, the damper, the smoke chamber, and the crown all affect how safely the fireplace operates. A pilot problem in a brand-new fireplace might be isolated, but in a 1960s brick ranch chimney with decades of humidity exposure and possibly an unpermitted gas log retrofit, the fireplace is part of a system. We camera the whole flue before we quote any repair. That’s how we keep you safe and avoid charging you twice.
It might be, but in Cloverleaf it’s often not, and the only way to know is with a camera. Many of these retrofits were done without permits or inspections because Cloverleaf is unincorporated Harris County and oversight was loose for decades. The gas line and damper modifications may be fine, or the logs may be venting into an unlined stack with a cracked clay-tile liner. We’ll run a camera, show you exactly what’s there, and give you a straight answer. If it’s safe, we’ll say so and you can keep using it. If it isn’t, you’ll see the evidence on the monitor before we quote anything.
Annually, and sooner if you’ve noticed any change in flame color, smell, or performance. Cloverleaf’s position downwind of the Ship Channel means your chimney cap, flashing, and crown are exposed to elevated sulfur dioxide and industrial particulates all year. Combined with Gulf Coast humidity, that accelerates corrosion and mortar decay even when the fireplace isn’t being used. An annual camera inspection catches those problems before they become expensive. We recommend scheduling it in early fall, before the first cold snap of the season.
No. We only recommend a liner when the camera footage proves the existing one is damaged or unsafe, and we’ll show you that footage on the monitor before we quote the work. If your clay-tile flue is intact and the gaps are acceptable, we’ll tell you that and document it in your inspection report. Ruben Castellano built this company in 2002 on the principle that homeowners deserve to see the evidence before they spend a dollar. That’s why we show you the camera feed in real time and hand you a written copy of whatever we find. Call (336) 863-3889 for an inspection and see for yourself.
