This page is for homeowners who bought a Gelco chimney cap, Gelco flue liner, or Gelco-mounted appliance between 2015 and 2023 and now need repair work done by someone who knows the product line without charging dealership rates. We’re not Gelco-authorized - we’re an independent Gelco service provider - and that means we source parts through Haven’s buying network to keep prices honest, not inflated.

How Gelco Products Fail - and How We Fix Them

• Gelco chimney caps (Model 1000 and 2000 series) - lid separation in freeze-thaw cycles. The stamped-steel lid on these caps traps water at the weld seam. In Lansdale, where January nights drop below 20°F and daytime sun hits south-facing caps hard, that trapped moisture expands and splits the seam in 4-7 years. We remove the cap, assess flue wall condition underneath, and install a replacement with a fully welded lid or upgrade to a Gelco-compatible cap from Olympia Chimney with a drip edge that sheds water before it reaches the seam.
• Gelco stainless flue liners - thermal fatigue at the flex-to-rigid transition. The multi-flex sections Gelco shipped in 2016-2019 used a lighter gauge at the collar joint. After repeated heating and cooling, that collar cracks vertically, leaking combustion gases into the masonry chase. We camera-scan to locate the crack precisely, then cut out the failed section and splice in a DuraFlex or HeatShield rigid transition of matching diameter - documented with photos under Haven Standard Clause 4.
• Gelco top-sealing dampers - cable housing corrosion from Lansdale’s clay-heavy runoff. The housing sits in a cast-aluminum frame that pits when acidic roof runoff pools against it, common on homes near the Neshaminy Creek watershed with older gutter systems. The damper won’t open fully, or the cable snaps. We replace the housing with a Famco stainless equivalent or rebuild the frame with copper flashing to break the galvanic reaction.
• Gelco chimney crowns - surface spalling from de-icing salt drift. Homes within two blocks of Main Street or Valley Forge Road get salt spray from winter road treatment. Gelco’s poured concrete crowns absorb it, and by year five the surface flakes off, exposing the mesh. We grind back to sound concrete, apply a CrownSeal or HeatShield resurfacing layer, and slope it to shed water - not just patch over the damage.
• Gelco wall-thimble assemblies - gasket hardening in gas-vent applications. The high-temp gasket between thimble sections dries out after 6-8 years of gas insert use, creating a gap that draws room air into the chase. We find this during Level 2 camera inspection when CO readings at the thimble register elevated. Replacement gaskets are Gelco-specific; we stock them, or fabricate a seal from Copperfield high-temp gasket material same-day.

Our Gelco Chimney Repair Process

1. 1
   Schedule and scope. You call (267) 327-4785. We ask the Gelco model or series if you know it, the installation year, and what you’re seeing - water, draft problems, debris, or visible damage. We book a Level 2 inspection, not a “look-see.”
2. 2
   Camera-scan diagnosis. Our tech runs the camera down the flue, photographs the crown, cap, and flashing from the roof, and records readings. Corrine Halstead reviews the footage before any price is written. The camera doesn’t guess. Neither do we.
3. 3
   Written price, written scope, written warranty. Haven Standard Clause 1: you get all three before work starts. If the fix needs Gelco OEM parts, we quote that. If a DuraFlex or HeatShield equivalent meets spec at lower cost, we quote both and explain the difference.
4. 4
   Repair and test. We do the work - repointing, rebuild, liner splice, cap replacement - then run a combustion or draft test to verify function. Photos of the completed repair go into your documented record under Haven Standard Clause 4.
5. 5
   Cleanup and follow-up. We haul debris, protect your landscaping with ground cloths (standard on every Lansdale job), and check in at 30 days. The 365-Day Done Right Promise covers labor and materials.

Why Lansdale Homeowners Call Level Two Chimney Lansdale for Gelco Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of Lansdale’s housing stock - the colonials near Merrick Road, the 1990s builds off Walnut Street, the converted farmhouses toward Hatfield - runs Gelco components installed during the 2015-2020 replacement boom. Corrine Halstead’s crew knows the difference between a Gelco Model 1000 cap that can be re-welded and one that’s past saving.

Our background-checked, uniformed technicians carry license numbers on every page and every truck. You get a text when your tech is en route. Calls are answered by a live person, 24/7. Materials come from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield through Haven’s buying network - no single-source markup, no pushing one brand because it’s the only one we stock.

The 365-Day Done Right Promise means if it’s not done right, we make it right. The documented photo record means you don’t take our word for it - you see what we saw.
