How Gelco Products Fail - and How We Fix Them

• Gelco UltraPro liner separation at the collar joint. We see this in Collegeville colonials built in the 1980s where the original UltraPro was retrofitted into a clay flue. The collar joint loosens after 15-20 years of freeze-thaw cycling in Montgomery County winters. We pull the liner, inspect the surround with our camera, and re-secure with a new Gelco collar or a DuraFlex equivalent if the homeowner prefers. The old collar goes in the photo record.
• Gelco Multi-Flue cap rust-through at the weld seam. The Multi-Flue cap uses a spot-welded seam where the lid meets the skirt. In homes near Perkiomen Creek with higher humidity, we find pinhole corrosion starting at year 8, not the advertised 15. We replace with a new Gelco cap or a Famco equivalent with fully seam-welded construction, depending on budget.
• Gelco liner sag in tall chimneys. The Gelco standard-duty liner lacks the internal wire reinforcement found in DuraFlex Pro. In Collegeville’s three-story Victorians along Main Street, we find sagging at the offset after 10-12 years. We either install a Gelco reinforced replacement or upsize to HeatShield Cerfractory foam if the flue geometry allows.
• Gelco crown wash cracking under spalling brick. When the brick above a Gelco liner spalls, the crown wash takes the stress. Gelco’s recommended crown mix is 1:1:1 cement-lime-sand, but we’ve found it too brittle for Pennsylvania’s 40-degree winter temperature swings. We repoint with a modified NHL 3.5 lime mix that flexes, then re-seat the cap.
• Gelco top-sealing damper cable freeze. The Gelco Lyemance-style damper uses a stainless cable that runs down the flue. In Collegeville homes with exterior chimneys, condensation freezes the cable to the liner wall by January. We replace the cable, insulate the chase, and document the repair with photos for the homeowner’s insurance file.

Our Gelco Chimney Repair Process

1. 1
   Call and schedule. A live person answers, 24/7. We book your NFPA 211 Level 2 inspection, which includes a full camera scan down the flue.
2. 2
   Inspection and documentation. Corrine Halstead or a background-checked, uniformed technician arrives with a text notification. We run the camera, identify the Gelco series and failure mode, and photograph everything.
3. 3
   Written price and scope. Before any repair begins, you receive a written price, written scope, and written warranty. Clause 1 of the Haven Standard requires it. No exceptions.
4. 4
   Parts decision. We source Gelco OEM parts through our Haven buying network when available and appropriate. If Gelco lead times stretch past two weeks or the part is discontinued, we quote a quality aftermarket equivalent from DuraFlex, HeatShield, or Olympia Chimney with equivalent or better specs.
5. 5
   Repair and test. We complete the repair, run a post-repair camera scan to verify liner integrity and proper draft, and test all moving components.
6. 6
   Photo record and guarantee. You receive a documented photo record of before, during, and after. Clause 4 of the Haven Standard requires this archive. The 365-Day Done Right Promise covers the work.

Why Collegeville Homeowners Call Emberly Chimney Cleaners Collegeville for Gelco Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a significant share of those were in Montgomery County homes with Gelco liners and caps installed in the 1990s and 2000s building booms. Our technicians know the difference between an UltraPro and a standard-duty liner without reading the stamp, because they’ve pulled enough of both to recognize the wall thickness by feel.

The 365-Day Done Right Promise means if a Gelco collar we sealed loosens or a cap we installed shifts, we return and make it right. No charge. No argument. Our background-checked crews arrive uniformed with license numbers visible, and you get a text when they’re on the way. Materials come from our Haven buying network, DuraFlex, HeatShield, and the other brands we trust, so your price reflects real procurement costs, not markup theatre.

Corrine Halstead still writes the price on the estimate sheet before she asks for a decision. That’s how she built this business, one inspection at a time.
