Gelco Chimney Cap & Crown Nationwide

Gelco Chimney Cap & Crown in Evanston: What to Know First

We provide independent Gelco chimney cap and crown service in Evanston, with most Gelco cap replacements and crown repairs completed in a single visit once we have the right part on the truck. A written price and scope are delivered before any work starts, and every job includes a camera-scan inspection and documented photo record under Clause 4 of the Haven Standard. Typical Gelco cap installations in Evanston run $340-$780 depending on flue count and whether the crown needs coating or rebuild work beneath it.

Call (708) 234-1174

This page is for homeowners who know they have a Gelco product on their chimney and need to know whether it can be repaired, what a proper replacement looks like, and what it will actually cost. If you’re seeing rust streaks on the brick below the cap, hearing a rattle in high wind off Lake Michigan, or looking at cracked crown concrete after another freeze-thaw winter, call us at (708) 234-1174. We’ll send a named technician with a camera, not a sales pitch.

How Gelco Products Fail - and How We Fix Them

• Gelco Ultra-Temp stainless caps: The 18-gauge lid on the Ultra-Temp series holds up well in Evanston’s salt-air lakefront conditions, but the spot-welded corner seams are the failure point. We’ve pulled dozens where the seam has opened just enough to let water wick behind the lid and freeze against the flue tile. We replace with a matched Gelco lid or, if the homeowner prefers, a heavier-gauge aftermarket equivalent with fully welded seams and a written warranty on the weld integrity.
• Gelco Multi-Flue caps with mesh sides: The 5/8-inch spark arrestor mesh on Gelco multi-flue units clogs with cottonwood seed in late spring across Evanston’s tree-canopied neighborhoods, especially near Centennial Park and the North Shore Channel. The mesh is factory-riveted, so cleaning without distortion is difficult. We remove the mesh section, clean or replace it, and re-rivet with stainless hardware. If the frame has warped from heat cycling, we document it and quote a replacement before installing.
• Gelco galvanized economy caps: These were common on spec-built homes in Evanston’s 2015-2019 construction wave, particularly in the west-end subdivisions. The galvanized coating fails at the drip edge first, usually within 4-6 years, and the underlying steel rusts through in sheets. We don’t re-coat these; we replace with stainless or copper-cap equivalents sourced through our Haven buying network, with the old cap photographed and the new one spec’d in writing before we start.
• Gelco crown-mounted caps with integral skirt: The skirt on these units is meant to shed water over the crown edge, but the skirt-to-crown seal is a single bead of caulk from the factory. In Evanston, where temperature swings of 40 degrees in a day are common in March and November, that bead cracks and lifts within two seasons. We remove the cap, grind the old sealant, re-bed with a flexible crown sealant compatible with Gelco’s skirt geometry, and re-mount with stainless fasteners at 6-inch centers, not the factory 12-inch spacing.
• Gelco top-sealing dampers integrated with cap frames: The cable-operated damper on Gelco’s combination cap-damper units seizes when the cable sheath fills with creosote dust and lakefront humidity. Homeowners in east Evanston near the lake call us thinking the cap is broken when it’s actually the damper cable frozen inside the cap frame. We diagnose this with the camera first, then disassemble the cap, clean or replace the cable assembly, and test the damper operation before we leave. The camera doesn’t negotiate, and neither does creosote.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and scheduling: A live person answers, checks Gelco part availability against your model if you know it, and books a window. You get a text when your technician is en route.
2. 2
   Camera-scan inspection (NFPA 211 Level 2): Before touching the cap or crown, we run the camera down the flue to document liner condition, creosote class, and any water damage pattern that would change the scope. This is Clause 4 of the Haven Standard, and we’ve done it on every job since 2009.
3. 3
   Written price and scope: Corrine Halstead or your assigned technician delivers a written price, written scope, and written warranty before any work begins. No exceptions. This is Haven Standard Clause 1: Have it in writing.
4. 4
   Parts decision: If your Gelco part is available through our Haven buying network at a fair price, we use it. If lead time is excessive or the OEM part has a known weakness we’ve documented in the field, we quote a quality aftermarket equivalent from DuraFlex or HeatShield with equivalent or better specifications, and you choose.
5. 5
   Repair or replacement: We execute the agreed scope, photograph every stage, and test the assembly for proper draft and water shedding with a controlled water stream.
6. 6
   Documentation and guarantee: You receive a photo record of the completed work, a written warranty, and the 365-Day Done Right Promise. If it’s not done right, we make it right.

Why Evanston Homeowners Call Emberly Chimney Cleaners Evanston for Gelco Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a significant share of the cap and crown work in Evanston involves Gelco products from the 2010s construction boom and earlier lakefront installations. Corrine Halstead and our crew know the Gelco catalog well enough to spot the economy-cap rust pattern from the ground and to know which Ultra-Temp seam failures are repairable versus replacement-only.

Because we source materials through the Haven buying network across multiple brands, including DuraFlex and HeatShield, we’re not locked into Gelco lead times or pricing when a faster or better-engineered solution exists.

Your photo record is archived under Clause 4. And the 365-Day Done Right Promise applies to every job, Gelco or otherwise.
