Gelco Chimney Repair Nationwide

Gelco Chimney Repair in Downers Grove: What to Know First

We provide independent Gelco chimney repair in Downers Grove, with most jobs quoted in writing during the first visit and completed within one to two weeks once parts are confirmed. As an independent Gelco service provider, we are not affiliated with or authorized by Gelco, which means we source parts through our Haven buying network and always show you camera evidence before quoting a dollar. Typical Gelco repairs in Downers Grove run $340-$1,800 depending on whether we’re repointing mortar, rebuilding a spalling crown, or replacing failed flashing on a multi-flue system. Corrine Halstead and our crew have worked on Gelco products throughout Downers Grove, including the older masonry installations near Main Street that were retrofitted with Gelco caps and liners in the 2010s.

How Gelco Products Fail - and How We Fix Them

• Gelco Multi-Flue Chimney Caps - corner-seam separation. The 304 stainless multi-flue caps installed on many Downers Grove split-levels from 2012-2018 develop water intrusion at the mitered corners where the lid meets the skirt. Freeze-thaw cycles in DuPage County accelerate the gap. We remove the cap, assess the crown beneath for saturation damage, and either re-seam with marine-grade silicone and stainless hardware or replace through our Olympia Chimney supply line if the metal has thinned.
• Gelco Lyemance/Lock-Top Dampers - cable fray and seal failure. The Lyemance top-sealing damper uses a stainless cable routed down the flue to a handle assembly. After 8-12 years, the cable frays where it passes the smoke shelf, and the silicone seal gasket hardens, letting conditioned air escape. We camera-inspect the cable path, replace with Gelco-spec cable or upgrade to a HeatShield-compatible assembly if the flue interior is irregular, and test seal compression with a draft gauge.
• Gelco Pre-Cast Concrete Crowns - spalling from chloride exposure. Gelco’s pre-cast crowns were marketed as “maintenance-free” in the early 2010s, but the mix design in certain lots was porous enough to absorb road salt mist from Downers Grove’s winter plowing. The surface spalls, the rebar corrodes, and water reaches the wythe (the gap between flue tile and brick). We remove the crown, repair the wythe with proper clearance, and pour a new cast-in-place crown with a drip edge and expansion joint - or spec a Gelco replacement if the dimensions match.
• Gelco Single-Flue Caps - mesh corrosion in coastal-wind corridors. The 5/8-inch mesh on Gelco single-flue caps corrodes faster than expected in pockets of Downers Grove where prevailing winds carry residual moisture from the Des Plaines River valley. The mesh collapses, squirrels enter, and the flue gets blocked. We replace with Copperfield 304 mesh or a full Famco cap if the flue tile has shifted.
• Gelco Chimney Pots - base flashing separation. The decorative chimney pots Gelco distributed through specialty dealers require a lead or copper base flashing that was often installed without a kickout diverter. Water runs behind the pot, rots the cricket (the peaked flashing behind the chimney), and enters the attic. We fabricate a proper cricket with step flashing, reset the pot with a bed of mortar, and document the repair with photos per Haven Standard Clause 4.

Our Gelco Chimney Repair Process

1. 1
   Call and schedule. A live person answers, checks our route for Downers Grove, and books a 90-minute arrival window. You get a text when the tech is en route.
2. 2
   NFPA 211 Level 2 inspection. We run a camera down the flue, inspect the exterior with binoculars, and photograph the Gelco component in question - cap, damper, crown, or flashing. The camera does not lie, and neither does the written price.
3. 3
   Parts decision. We identify whether your Gelco part is still manufactured, whether an aftermarket equivalent from DuraFlex or HeatShield meets the spec, and whether Gelco’s original warranty (if any remains) would be affected by non-OEM replacement. You see the options in writing.
4. 4
   Written price and scope. Before any work starts, you receive a written price, written scope, and written warranty - Haven Standard Clause 1, H.A.V.E.N. “Have it in writing.” No exceptions.
5. 5
   Repair and test. We complete the repair, run a post-job camera scan or water-test for flashing, and record the results. The photo record uploads to your job file under Haven Standard Clause 4.
6. 6
   Cleanup and guarantee. We haul away debris, leave the work area as found, and stamp the job with our 365-Day Done Right Promise. If it’s not done right, we make it right.
