Gelco Chimney Repair Nationwide

Gelco Chimney Repair in Denton: What to Know First

We provide independent Gelco chimney repair in Denton, typically scheduling within a week and completing most jobs in one day. Our written price arrives before any work starts, and every repair includes a camera-scan inspection with documented photos under Haven Standard Clause 4. Gelco products are common in Denton homes built between 2005 and 2018, particularly their pre-fabricated chimney systems and stainless steel liner kits, and we’ve handled their specific failure patterns since opening here in 2009. If you own a Gelco chimney component and have noticed mortar loss, water staining, or draft issues, call us at (940) 373-6912 for a free estimate with no obligation to book.

How Gelco Products Fail - and How We Fix Them

• Gelco Pro-Fab chimney chase covers (2008-2016 series) - The galvanized steel in this run was stamped with a center-seam design that pools water during Denton’s spring storm season. We see rust-through at the seam within 8-12 years, often misdiagnosed as a roof leak. We replace with a Gelco-compatible stainless chase cover or, when the chase framing is still sound, a custom-fabricated unit with cross-break stamping to shed water. The camera doesn’t guess - and neither do I.
• Gelco UltraPro liner kits (304-grade, 2010-2014 production) - These liners came with expansion joints rated for 1,200°F continuous, but Denton’s heavy oak and pecan burns (common in neighborhoods near North Lakes Park) push sustained flue temps higher than the spec. We find longitudinal cracking at the first joint above the smoke chamber, usually at year 6-9. We sleeve with a 316Ti upgrade or, if the chase allows, a DuraFlex or HeatShield alternative with higher thermal tolerance.
• Gelco traditional masonry crowns poured over clay flue liners - The Gelco spec called for a 2-inch overhang minimum, but their crews in the Texas market often poured flush to the brick to speed production. Water runs straight down the brick face, accelerating spalling in Denton’s freeze-thaw cycles. We cut back to sound concrete, pour a new crown with proper drip edge, and seal with a vapor-permeable waterproofing agent.
• Gelco factory-built fireplace chase wraps (vinyl-sided models, 2005-2012) - The OSB sheathing behind the vinyl wasn’t rated for the humidity spikes Denton sees when warm Gulf air hits a cooled chase after a cold snap. We find delamination and mold at the chase base, often hidden until the camera reveals staining on the interior framing. We strip to studs, replace with pressure-treated or composite sheathing, and re-side with proper venting per NFPA 211.
• Gelco chimney cap spark arrestors (universal-fit models) - The mesh on these caps was 5/8-inch, which catches Denton’s cottonwood fluff and post-oak catkins each April and May. Homeowners burn with restricted draft, then call us for “smoke backup” that’s actually a clogged cap. We clean or replace with a 3/4-inch mesh Gelco equivalent or a Famco model with better debris shedding, depending on your tree canopy.

Our Gelco Chimney Repair Process

1. 1
   Call and schedule. A live person answers, day or night. We ask for your Gelco model series if you know it, then book a Level 2 inspection with camera.
2. 2
   Inspection and documentation. Corrine Halstead or a uniformed, background-checked technician arrives with a text-on-the-way alert. We run the camera down the flue, photograph the failure, and record readings. You see the footage before we discuss price.
3. 3
   Written scope and price. Haven Standard Clause 1: written price, written scope, written warranty before any work starts. For Gelco repairs, we specify OEM versus aftermarket parts and explain the trade-off. No surprises.
4. 4
   Repair with correct materials. We source Gelco-compatible components through our Haven buying network, with DuraFlex or HeatShield alternatives when they outperform the original spec. We don’t substitute without documenting why.
5. 5
   Post-repair camera verification. Haven Standard Clause 4 requires a photo record on every job. We run the camera again to confirm the fix, then provide your documented record.
6. 6
   Cleanup and guarantee. We leave the work area clean. The 365-Day Done Right Promise applies from day one. If it’s not right, we make it right.
