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.
Gelco Fireplace Services in Fort Worth: What to Know First
We provide independent Gelco fireplace services across Fort Worth, from gas valve tune-ups in Ridglea to firebox rebuilds near the Cultural District. Most Gelco jobs are diagnosed and quoted same-day, with a written price before any work starts and a photo record when we’re done. A standard Gelco gas fireplace service runs $189-$279; wood-burning firebox repairs typically fall between $340-$780 depending on refractory panel condition.
This page is for Fort Worth homeowners who own a Gelco fireplace, insert, or gas log set and need service from a technician who knows the difference between a GVF36 vent-free unit and a GDIZC direct-vent insert without reading the manual on your porch. Call (682) 499-2712 for a free estimate, or read on for the specific failure modes we’ve documented on Gelco products in Tarrant County.

How Gelco Products Fail - and How We Fix Them
- GVF36/GVF42 vent-free series: thermopile voltage drop. These units lose pilot reliability when the thermopile drops below 325 mV, which happens faster in Fort Worth’s hard water zones because mineral scale builds on the pilot assembly. We clean the orifice with a proper pilot reamer, test millivolt output with a calibrated meter, and replace only if readings stay below spec after cleaning. Most GVF36 calls in Benbrook and Westover Hills trace to this exact issue.
- GDIZC direct-vent inserts: failed blower motors. The OEM Fasco blower on early GDIZC units draws high amperage and burns out after 6-8 seasons of Fort Worth’s freeze-thaw cycling. We stock a sealed-bearing aftermarket replacement that pulls 0.8 amps versus the original’s 1.4 amps, runs quieter, and carries the same 1-year warranty. We always test draft pressure after blower swap; a weak draft plus a new motor just burns out the next motor.
- Pre-fab wood-burning fireboxes: cracked refractory panels. Gelco’s factory-built fireboxes use 1-inch refractory panels that spall (flake and crumble) when subjected to Fort Worth’s sudden temperature swings, common when homeowners crank the thermostat after a cold front. We source replacement panels through our Haven buying network, cut them to fit on-site if OEM panels are discontinued, and document panel thickness and clearances with photos per Haven Standard Clause 4.
- GVF vent-free logs: sooting from improper ember placement. Homeowners who rearrange logs during cleaning often block the burner ports, causing yellow flame and carbon monoxide risk. We re-position per Gelco’s diagram, check ODS (oxygen depletion sensor) function with a manometer, and show the owner the before-and-after flame pattern on camera. This is not a “cleaning”; it’s a combustion safety check.
- Chimney-top dampers on Gelco wood units: corrosion at the cable pivot. Gelco’s top-sealing dampers use a stainless cable that corrodes where it exits the flue cap, especially in Fort Worth’s hail-prone spring seasons when cap seals degrade and water tracks down the cable. We replace the cable assembly, reseal the cap with high-temp silicone, and test damper closure with a smoke pencil to confirm the seal.
Our Gelco Fireplace Services Process

- 1
Call and schedule. A live person answers, confirms your Gelco model if you have it, and books a window. You get a text when your tech is en route.
- 2
NFPA 211 Level 2 inspection. Camera down the flue for wood-burning units; combustion analysis and gas leak detection for gas units. We document everything before touching a tool.
- 3
Written diagnosis and price. You get a written scope, written price, and written warranty before work starts. Haven Standard Clause 1. No exceptions.
- 4
Parts decision with full disclosure. We show you OEM versus quality aftermarket options, explain warranty implications, and source through our Haven network from Gelco, DuraFlex, HeatShield, or other approved suppliers. You choose; we don’t choose for you.
- 5
Repair and live testing. Gas units get a full firing sequence test, draft test, and CO reading at the face. Wood units get a smoke test and damper function check. The camera goes back down for after photos.
- 6
Photo record and guarantee. You receive a documented photo record under Haven Standard Clause 4, plus the 365-Day Done Right Promise. If it’s not right, we make it right.

Why Fort Worth Homeowners Call Level Two Chimney Fort Worth for Gelco Work

We’ve inspected and serviced more than 38,000 chimneys and fireplaces since 2009, and Gelco products show up regularly in Fort Worth’s 1990s-2010s subdivisions, from Arlington Heights to Mira Vista. Corrine Halstead trained at Apex Technical School in Manhattan before running crews here for the better part of two decades, and she built our process around what she wished existed: show the owner what’s wrong, name the price before the truck is unpacked, and leave a record that outlives the warranty.
Our technicians are background-checked, uniformed, and assigned by name. The license number is on every page. We source materials through our Haven buying network from Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield, which keeps pricing honest and options open when a Gelco part is back-ordered or discontinued. The camera doesn’t lie - and neither does the written estimate.
FAQs
No. As an independent Gelco service provider, we use OEM or equivalent parts and document our work to manufacturer standards. Gelco’s warranty covers defects in materials and workmanship, not who performs routine service. We keep part numbers and installation photos on file if you ever need to file a claim.
Common parts like thermocouples, blowers, and refractory panels ship to our warehouse in 2-4 business days. Discontinued GVF series parts may take 7-10 days or require a quality aftermarket equivalent, which we’ll discuss with you in writing before ordering. Call (682) 499-2712 to check availability for your specific model.
Replace if the firebox is cracked through to the metal wrapper, if the gas valve is obsolete and no replacement is manufactured, or if repair costs exceed 60% of a new unit installed. Repair if the issue is isolated to a blower, pilot assembly, or refractory panel. We show you the camera footage and the math, then you decide. No pressure.
Annually, per NFPA 211. Fort Worth’s dust, pollen, and hard water scale the burner orifices faster than coastal climates. Even a gas fireplace that “looks fine” can develop incomplete combustion, CO risk, or pilot degradation. The inspection takes 60-90 minutes and includes a documented photo record under Haven Standard Clause 4.
Class III creosote (the hard, glazed kind) builds up, increasing chimney fire risk. Spalling refractory panels can expose metal framing to direct flame, creating a house fire path. Carbon monoxide can backdraft if the damper or flue is obstructed. These are real hazards, not scare tactics, and they’re preventable with annual inspection. Call (682) 499-2712 for a free estimate.
