Call (331) 253-4980

This page is for homeowners who already have a Gelco cap or crown on their chimney and need someone who knows the product line well enough to source the right part without guessing. We’re not a Gelco dealer, and we’re not affiliated with the manufacturer. As an independent Gelco service provider, we work with what is actually on your flue, match it to available inventory, and tell you upfront whether OEM or quality aftermarket makes more sense for your situation. If you’re in Downers Grove, Lisle, or Woodridge and your Gelco cap is rattling, rusting, or missing entirely, call (331) 253-4980. Estimates are free, and we answer live 24/7.

How Gelco Products Fail - and How We Fix Them

• Gelco Multi-Flue caps with the original 304-grade mesh develop pinhole corrosion at the screen-to-hood weld after 8-12 years in Downers Grove’s freeze-thaw cycle. Road salt aerosol from I-355 and I-88 accelerates the attack. We replace with 316-grade mesh or full cap replacement depending on hood integrity, and we document the weld condition with camera photos before quoting.
• Gelco Single-Flue caps with the snap-leg mounting system lose tension in the stainless legs after repeated thermal cycling. The cap lifts in wind, sometimes vanishing entirely after a March storm. We see this on the GS series more than the GL line. Our fix: inspect the flue tile lip for chips, then install either a new Gelco leg kit or convert to a screw-mount base plate if the tile edge is compromised.
• Gelco crown-mounted caps on older Downers Grove homes near Main Street often sit on crowns that were never properly sloped for drainage. Water pools behind the cap flange, freezes, and pushes the cap outward while spalling the crown surface underneath. We remove the cap, repair or coat the crown with proper pitch, then reinstall with a bead of high-temp silicone that won’t trap water.
• Gelco wind-directional caps (the GWD series) seize in one position when the bushing grease dries out, usually after 5-7 years of summer heat and winter neglect. The cap stops rotating, which defeats the purpose and creates a downdraft path. We disassemble, clean the bushing track, relubricate with high-temp bearing grease, and replace the bushing if it’s galled. Full cap replacement is only needed if the hood is cracked from wind fatigue.
• Gelco chase covers on prefab chimneys in the Fairview and Highland Hills areas rust at the field-welded corners where the factory powder coat thins. Gelco chase covers are galvanized steel with a baked finish, not stainless, so once the breach starts it spreads fast. We measure in person, fabricate a replacement from 304 stainless or copper through our Haven buying network, and install with proper counter-flashing. The camera goes down the flue first to confirm no water damage to the firebox below.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, notes your Gelco model if you know it, and books a window. You get a text when your tech is en route.
2. 2
   Camera inspection first. We run the camera down the flue before touching the cap or crown. Clause 4 of the Haven Standard requires a photo record on every job, and for Gelco work we want to see if water infiltration has already damaged the liner or smoke chamber. The camera does not lie, and neither does the written price.
3. 3
   Diagnose and quote in writing. We name what we found, show you the footage, and deliver a written price with scope and warranty before any work begins. No verbal estimates, no scope creep.
4. 4
   Source the right part. For Gelco caps, we check OEM availability against our Haven network inventory. Sometimes Gelco OEM is back-ordered; sometimes a quality aftermarket cap from Famco or Olympia Chimney matches better at a lower price. We explain the trade-off and let you decide.
5. 5
   Execute and document. Cap or crown work is completed, the flue is camera-checked again for obstruction, and you receive a photo record, written scope, and warranty documentation.
6. 6
   365-Day Done Right Promise. If anything fails due to our work or the part we selected, we make it right. That’s stamped on every job.

Why Downers Grove Homeowners Call Emberly Chimney Cleaners Downers Grove for Gelco Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a healthy share of those have been Gelco caps in DuPage County split-levels and colonials. Corrine Halstead and our crew know the difference between a GS and GL series leg mount without climbing down to check the stamp, which saves time and avoids the wrong part on the truck.

Our background-checked, uniformed technicians carry license information on every page and every job. You get a named tech, a text when they’re close, and a documented photo record under Haven Standard Clause 4 - not because you asked, but because we started doing it in 2009 and never stopped. If you have a written estimate from another company, we’ll give you a free second opinion. And if your Gelco job also turns up liner or masonry needs, we carry DuraFlex, HeatShield, and other materials through our Haven buying network so you’re not coordinating multiple contractors.
