Gelco Chimney Liner & Rebuild in Houston, TX

Gelco Chimney Liner & Rebuild in Houston: What to Know First

As an independent Gelco service provider, we repair and replace Gelco chimney liners and rebuild affected structures across Houston, with most jobs completed in a single visit and upfront pricing before any work begins. A typical Gelco liner replacement runs between $2,800 and $4,500 depending on flue configuration, while partial rebuilds start around $3,200 and full chimney rebuilds range from $8,500 to $14,000 in the Houston market. Dale Hutchins and our team have worked on Gelco systems in Heights bungalows, Memorial ranch houses, and Meyerland splits long enough to know which model lines crack under Gulf Coast humidity and which ones hold. This page is for homeowners who already own a Gelco product and need straight talk on what’s failing, what it costs, and who can fix it without the runaround.

How Gelco Products Fail - and How We Fix Them

• Gelco Stainless Pro series: weld-seam corrosion at the collar joint. The Pro line uses a single-seam construction that traps condensation where the collar meets the flue body. In Houston’s spring and fall, when outdoor humidity swings 40 points in a day, that trapped moisture eats the seam from the inside. We’ve pulled Pros in River Oaks with collars that looked fine from the firebox but were paper-thin above the smoke chamber. We cut back to sound metal and sleeve with a DuraFlex equivalent or source Gelco OEM if the homeowner prefers - both carry our 90-Day Done Right Promise.
• Gelco Flex-Liner 316Ti: titanium stabilization layer delamination in high-heat appliances. The 316Ti flex liner was marketed for its acid resistance, but we’ve found the titanium layer can separate from the 316 stainless core when paired with older wood stoves that burn hot and fast. The symptom is a metallic rattle during burn-down, often misdiagnosed as a loose damper. In Spring Branch last year, we traced that rattle to a delaminated 25-foot run that had lost 60% of its wall integrity. We replaced with HeatShield Cerfractory Foam where the flue was straight enough, and a new Gelco rigid run where offsets demanded it.
• Gelco Pre-Fab chimney systems: chase pan failure leading to liner saturation. The factory chase pans on Gelco pre-fabs from the 1990s and early 2000s were galvanized steel with a 12-year realistic lifespan in Houston’s UV and rain cycle. When the pan rusts through, water follows the chase wall and pools on the liner collar, accelerating corrosion at the point of greatest stress. We replace with a copper or stainless chase pan from Copperfield, inspect the full liner length with our camera, and document everything - photos you can see, a plain-English verdict.
• Gelco Oval-to-Round adapters: creosote bridging at the transition. These adapters were common in 1980s Houston remodels where a round liner was forced into an oval clay flue. The geometry creates a ledge that catches creosote, especially with pine and post-oak burns common in north Houston. After two chimney fires in Kashmere Gardens traced to the same adapter design, we now spec a full oval liner or a proper clay-to-stainless transition - no more adapters, no more ledges.
• Gelco Multi-Flue liners: cross-flue leakage in shared chase construction. Some Tanglewood and Bellaire townhomes from the 1970s used Gelco multi-flue liners in a single chase with inadequate separation. When one flue develops a breach, exhaust can cross into the neighbor’s flue - a silent hazard until a Level-2 camera catches it. We isolate with a partial rebuild of the wythe, install independent liners, and pressure-test before we sign off. A clean flue doesn’t announce itself. That’s the point.

Our Gelco Chimney Liner & Rebuild Process

1. 1
   Call and schedule. A live person answers, day or night. We ask about the appliance, the symptoms, and the home’s age to pre-stage likely parts.
2. 2
   Level-2 camera inspection. Our technician runs a camera the full flue length, photographs every joint, breach, and creosote deposit, and delivers a plain-English verdict on the spot - documented like an engineer, explained like a craftsman.
3. 3
   Parts decision: OEM Gelco, DuraFlex, or HeatShield. We stock common Gelco diameters and carry DuraFlex and HeatShield as alternatives when geometry or budget favors them. We explain the trade-offs - warranty terms, expected lifespan, compatibility - and you choose. No surprises on the bill.
4. 4
   The repair or rebuild. Background-checked, uniformed technicians complete most Gelco liner replacements and partial rebuilds in a single visit. Full rebuilds typically take two to three days, weather permitting. We protect floors, haul away debris, and run a final camera pass.
5. 5
   Combustion safety test and documentation. We verify draft, spillage, and clearances match NFPA 211 and Houston amended code, then hand you the report, the photos, and the written 90-Day Done Right Promise.
6. 6
   Follow-up. We call within two weeks to confirm performance. If anything’s off, we come back. In writing, no arguing.

What Gelco Chimney Liner & Rebuild Costs in Houston

These are real numbers for the Houston market, based on jobs we’ve completed in the last eighteen months. Every home is different, but this is the range you should plan for:

Factors that push costs up: homes over two stories, chase enclosures that need reframing, and the rare Gelco oval or square liner that requires custom fabrication. Factors that keep costs down: straight flues, good roof access, and catching damage before it reaches the firebox. We provide no-hassle upfront pricing - the number on the estimate is the number on the invoice. Call (877) 516-5603 for a free estimate; we’ll be there when we say.
