How Gelco Products Fail - and How We Fix Them

• Gelco Pro-Series stainless caps corrode at the base flange in Cambridge’s freeze-thaw cycle. The 304-grade seam sits right at the crown line, and when road salt aerosol drifts in from Mass. Ave. or Memorial Drive, the crevice between cap and crown accelerates galvanic corrosion. We remove the cap, assess the crown substrate, and either reseat on a new Gelco base or fabricate a custom copper or 316-grade replacement through our Haven buying network.
• Gelco UltraPro multi-flue caps collect ice dams that split the mesh screen. The 18-10 mesh is tight enough to stop animals but traps freeze-thaw condensation in Cambridge’s January-February temperature swings. We see this on triple-deckers near Inman Square where interior heat drives moisture upward. We replace with expanded 5/8-inch mesh or install a HeatShield smoke chamber seal to reduce the moisture source.
• Gelco cast-in-place liner systems (1985-2005 installs) develop circumferential cracking at the first offset. The refractory mix was sensitive to rapid curing, and Cambridge’s older masonry - especially the soft brick in 1890s-1920s rowhouses off Hampshire Street - shifts microscopically with seasonal humidity. We camera-map the crack pattern. If it’s under 1/8-inch and isolated, we seal with HeatShield Cerfractory Foam. If it’s through-wall or multi-point, we pull a DuraFlex 316Ti liner and abandon the Gelco cast-in-place.
• Gelco pre-fab chimney chase covers (galvanized steel, 1998-2010) rust from the underside out. The factory edge-roll traps condensation against the wood chase top. By the time you see rust streaks on the siding, the underlying OSB is often punky. We fabricate a replacement from 24-gauge stainless or copper with a drip edge and counterflashing, and we write the substrate condition into the scope before touching anything.
• Gelco clay flue liners in Cambridge’s salt-air exposure spall at the flue gas interface. The 9×13 and 13×13 terra cotta units common in 1960s-1980s Cambridge builds absorb chlorides from coastal air that reaches even inland neighborhoods on southwest winter storms. The spalling flakes into the flue, creating blockage points. We remove the damaged sections with rotary extraction, camera-verify the full run, and install a DuraFlex or Olympia Chimney stainless liner sized to the appliance.

Our Gelco Chimney Repair Process

1. 1
   Call and schedule. A live person answers. We ask the Gelco product line if you know it, the install or last service date, and what you’re seeing - water, draft issues, debris, or visible damage. We assign a named technician and text when they’re en route.
2. 2
   NFPA 211 Level 2 inspection with camera. Corrine Halstead’s crews have been running cameras up flues since 2009. For Gelco systems, we document the product label, serial or date stamp if accessible, and the exact failure mode. The camera doesn’t editorialize - it just shows you what’s there.
3. 3
   Written price and scope before any work. Haven Standard Clause 1: have it in writing. We specify OEM Gelco parts, quality aftermarket through our buying network, or hybrid solutions. You see the part numbers, the labor hours, and the warranty terms. No work starts until you approve in writing.
4. 4
   Repair with brand-appropriate methods. For active Gelco warranties, we use warranty-safe practices - no field-modification of listed assemblies, no substitute fasteners on cap mounts. For out-of-warranty systems, we source compatible materials from Gelco, Olympia Chimney, or Famco depending on availability and honest price.
5. 5
   Post-repair camera verification and photo record. Clause 4 of the Haven Standard requires a documented photo record on every job. You get the images, the written warranty, and the invoice with the 365-Day Done Right Promise stamped on it.
6. 6
   Cleanup and archive. We haul debris. Your documented record goes into our archive - 38,000+ jobs and counting - so the next tech knows exactly what Gelco product was installed and how it was repaired.

Why Cambridge Homeowners Call Level Two Chimney Cambridge for Gelco Work

We’ve put cameras up flues in triple-deckers near Inman Square and century-old rowhouses a block off the Charles. Corrine Halstead learned the trade at CUNY Kingsborough’s building construction technology program, then spent the better part of two decades running crews through Greater Boston. She writes findings in plain numbers - what was found, what it costs to fix, what happens if you don’t - before asking anyone to decide.

The 365-Day Done Right Promise means if it’s not done right, we make it right. Background-checked, uniformed technicians. License number on the page. Materials sourced through Haven’s buying network from Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield - not because we carry every brand, but because Gelco systems sometimes need a multi-brand solution and we don’t pretend otherwise.

Live phone support, 24/7. A named tech. A text when they’re on the way. And every job starts with a written price, not a surprise.
