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.

AfterGelco Chimney Liner & Rebuild in Fort Worth: What to Know First
We provide independent Gelco chimney liner and rebuild service in Fort Worth, typically completing liner replacements in one to two days and partial rebuilds within three to five days depending on weather and brick matching. Every job starts with a written price on paper before any work begins, and every finished job carries our 365-Day Done Right Promise under the Haven Standard. This page is for Gelco owners in Fort Worth who’ve been told they need a new liner, a partial rebuild, or a full chimney rebuild and want to know what they’re actually paying for before a truck rolls. Call us at (682) 499-2712 or read on for the specifics.
How Gelco Products Fail - and How We Fix Them
- Gelco Stainless Pro series: weld-seam corrosion at the flex points. The Pro’s 316Ti alloy handles Fort Worth’s flash-humidity cycles well, but the longitudinal weld seam at each corrugation can develop pinhole oxidation where condensation pools. We see this most in Tanglewood and Ridglea Hills homes with exterior chimneys that cool overnight. Our fix is a full Gelco-compatible replacement with a seamless-drawn 316Ti liner, or if the budget’s tight and the damage is localized, a HeatShield cerfractory seal at the breach plus a new Gelco connector, both documented with pre- and post-camera footage under Haven Standard Clause 4.
- Gelco UltraFlex: over-compression during original installation. UltraFlex is designed for tight flues, but we’ve found original installers in Fort Worth’s 1950s-1970s housing stock near the Cultural District sometimes compressed the corrugations too aggressively to get past a narrow smoke chamber. The liner never fully recovers its diameter, draft drops, and creosote accumulates in the low spots. We pull the damaged section, measure the actual flue geometry with a video scan, and install a properly sized Gelco or DuraFlex replacement with an insulated wrap where the clearances demand it.
- Gelco oval-to-round adapters: thermal fatigue at the weld. These adapters see the highest thermal stress in the system, and in Fort Worth’s freeze-thaw winters, the differential expansion between the oval inlet and round outlet can crack the adapter weld after seven to twelve years. We stock Gelco OEM adapters, but we also source compatible units through our Haven buying network when supply runs thin. The replacement gets a new top plate and storm collar, and we pressure-test the joint before we leave.
- Gelco rigid liner systems: settlement separation at the tee. Rigid Gelco lines in two-story Fort Worth homes with clay flues sometimes separate at the tee connection when the surrounding structure settles, which is common in the gumbo clay soils of the Benbrook and Wedgwood areas. The gap pulls combustion gases into the chase. We reseat the tee with a Gelco-compatible expansion joint, re-support the liner at mid-height, and seal the chase top with a custom-fabricated chase cover from our Famco supply line.
- Gelco top-terminated liners: cap and storm collar degradation. The standard Gelco rain cap in 304 stainless lasts roughly eight to ten years in Fort Worth’s hail corridor before the mesh screen fatigues and the storm collar gasket hardens. Water follows the liner back down, spalling the crown and rusting the top plate. We replace with a Gelco 316Ti cap or a Copperfield equivalent with a silicone storm collar, and we document crown condition with photos so the homeowner sees whether crown repair can wait or needs to happen now.
Our Gelco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, day or night. We book a Level 2 inspection with camera scan, and you’ll get a text when your tech is en route.
- 2
Inspection and documentation. We run the camera the full length of the flue, record the liner condition, measure clearances, and check for combustible contact. You get the footage and a written scope with a fixed price before we load any tools.
- 3
Parts decision. If Gelco OEM is available and appropriate, we quote it. If supply is backordered or an aftermarket DuraFlex or HeatShield solution meets the spec at lower cost, we explain the trade-off and let you decide. No parts go in without your written approval.
- 4
Repair or rebuild. Liner replacement happens top-down through the crown or bottom-up through the firebox, whichever protects your finishes. Partial rebuilds get brick-matched from our local Fort Worth masonry suppliers. Full rebuilds include a new crown, flashing, and cap as standard.
- 5
Testing and sign-off. We pressure-test or smoke-test every liner installation, re-run the camera to confirm proper seating, and leave you with a photo record, written warranty, and the 365-Day Done Right Promise stamped on your invoice.
- 6
Cleanup and archive. We haul away all debris, sweep the work area, and upload your documented record to our archive under Haven Standard Clause 4, where it stays accessible if you ever need it for insurance or resale.

Why Fort Worth Homeowners Call Level Two Chimney Fort Worth for Gelco Work
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a significant share of those have been Gelco-lined systems in Fort Worth’s older housing stock. Corrine Halstead, our owner, learned the trade at Apex Technical School in Manhattan and has spent the better part of two decades running crews across Fort Worth, including plenty of calls near the Cultural District where older homes hide older problems. She shows up with findings already written down - photos, measurements, and a price on paper before anyone has to ask. The camera doesn’t lie, and neither does the written estimate.
Our technicians are background-checked, uniformed, and assigned by name, not dispatched from a pool. We source Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield materials through our Haven buying network specifically to keep customer prices honest. If a competitor’s written quote has you uncertain, bring it in - our Free Second Opinion policy means we’ll review it against what we find, no charge. Every job is backed by the 365-Day Done Right Promise: if it’s not done right, we make it right.
FAQs
No - as an independent Gelco service provider, we perform repairs and replacements that comply with Gelco’s installation specifications, and we document our work with photos and written scope so any warranty claim you file with Gelco has the evidence it needs. We are not affiliated with or authorized by Gelco, but we follow their clearances, connector requirements, and termination specs precisely. Call (682) 499-2712 if you want us to review your warranty paperwork before we start.
Most Gelco liner replacements in Fort Worth are completed in one to two days, with the second day reserved for mortar curing or final testing if needed. A partial rebuild adds one to three days for brick matching and weather delays. We don’t promise same-day completion because the work has to be done right, not fast. Call (682) 499-2712 for a written timeline with your estimate.
Sometimes - if the camera shows a single localized breach, no combustible contact, and the surrounding liner is in sound condition, we can apply a HeatShield cerfractory seal or install a Gelco repair sleeve. If the liner has multiple breaches, corrosion at the welds, or any section pulling away from the flue wall, replacement is the only safe option. We show you the camera footage and explain which category you’re in before any price is discussed. Call (682) 499-2712 to schedule the inspection.
We maintain stock of common Gelco liners, adapters, and caps, and our Haven buying network gives us access to DuraFlex and Olympia Chimney equivalents that meet or exceed the same 316Ti and AL29-4C specifications. If an OEM part is backordered, we quote the equivalent with full documentation of the spec match - no substitutions without your written approval. Call (682) 499-2712 and we’ll check availability for your specific model.
The camera decides this, not a salesperson. If the liner is compromised but the surrounding masonry, crown, and smoke chamber are sound, a liner replacement solves the problem. If we find spalling brick, a cracked crown, or a smoke chamber that fails NFPA 211 clearance requirements, a partial or full rebuild is necessary to make the system safe. We separate the two scopes in our written estimate so you can phase the work if budget requires. Call (682) 499-2712 for the camera inspection - estimates are free.
