Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterGelco Chimney Cap & Crown in Hoffman Estates: What to Know First
We provide independent Gelco chimney cap and crown service in Hoffman Estates, with most cap replacements and crown repairs completed in a single visit once parts are confirmed. A written price arrives before any work starts, and every job includes a camera-scan inspection with a documented photo record under Clause 4 of the Haven Standard. If you own a Gelco cap or crown in Hoffman Estates and you’re seeing rust bleed, mortar crumble, or water stains on the firebox, call (331) 200-4445 for a free estimate. We source Gelco materials through Haven’s buying network alongside DuraFlex, HeatShield, and other lines, and we keep common Gelco sizes in regional stock to avoid the three-week backorder that kills most schedules.
How Gelco Products Fail - and How We Fix Them
- Model A-1 single-flue caps with 304 stainless hoods - The spot-welded seam at the hood peak splits after 7-10 winters in Hoffman Estates’ freeze-thaw cycle. We’ve pulled twelve of these off roofs in the Barrington Road corridor since 2022. We replace with a hand-seamed or fully welded hood, or step up to the Gelco Model B multi-flue cap if the flue tile spacing allows it.
- Multi-flue Model B caps with galvanized mesh - The 18-gauge galvanized screen rusts from the inside out where creosote vapor condenses, especially on fireplace chimneys that vent into cold Hoffman Estates air for six months straight. Homeowners smell it before they see it: a metallic, sour draft on startup. We spec 304 or 316 stainless mesh on replacement, which Gelco offers but big-box retailers rarely stock.
- Model C top-mount dampers with integrated caps - The cast aluminum damper frame warps if the chimney crown beneath it has settled even 1/8 inch. The damper seal fails, the cap tilts, and rainwater runs directly into the flue. We crown-level with CrownCoat or pour a new concrete crown before remounting, or the warp returns in two seasons.
- Gelco chase covers on factory-built chimneys - The stamped drip edge on pre-2015 covers holds water against the chase siding instead of shedding it. In Hoffman Estates, that trapped water freezes, expands, and pushes the cover corners up. We install a custom-fabricated chase cover with a 2-inch minimum drip edge and cross-break, or switch to a Gelco cap-and-flue combo if the chase top is sound.
- Crown wash under Gelco caps - Gelco’s mounting hardware is 3/8-inch lag bolt, which is fine for new concrete but pulls loose from a crown that’s already spider-cracked. We see this on 1990s Hoffman Estates builds with original crowns that were never more than a thin mortar wash. We pull the cap, grind the crown to solid substrate, pour a minimum 2-inch structural crown with proper overhang, then remount with expansion anchors set into the new pour.
Our Gelco Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, 24/7. We ask for the cap model if you know it, the chimney type (masonry or factory-built), and what you’re seeing. We book a 90-minute arrival window.
- 2
Camera-first inspection. Our tech runs a chimney camera before touching the cap. Clause 4 of the Haven Standard requires it. We document flue condition, liner integrity, and water damage trace - because a cap failure often hides liner damage below. Corrine Halstead’s rule: camera first, price second, pen third - in that order every time.
- 3
Parts decision. If it’s a stock Gelco size, we quote OEM. If Gelco lead time exceeds ten days or the original design is obsolete, we quote a quality aftermarket equivalent from Olympia Chimney or Famco with equivalent gauge and mesh spec. You get both options in writing.
- 4
Written price, written scope, written warranty. Haven Standard Clause 1. No work starts until you have all three. The price is flat; the scope names every part and operation; the warranty is the 365-Day Done Right Promise.
- 5
Repair and test. Cap or crown work is done, then we run a water test (simulated driving rain with a garden sprayer on the cap for five minutes) and a final camera pull to confirm no debris entered the flue during work.
- 6
Documentation and cleanup. You receive the photo record, the written invoice, and the warranty card before we leave. Everything goes into your file in our system and, if you want, emailed to you before the truck pulls away.

Why Hoffman Estates Homeowners Call Level Two Chimney Hoffman Estates for Gelco Work
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a measurable slice of those were Gelco caps in Hoffman Estates and the northwest suburbs. Our techs know the difference between a Model A-1 and a Model B-2 without climbing down to check the stamp. When Gelco parts are backordered, we have DuraFlex, HeatShield, Olympia Chimney, and Famco equivalents in our network that meet or exceed OEM spec, so you’re not waiting three weeks for a $40 base ring.
Every job carries the 365-Day Done Right Promise: if it’s not done right, we make it right. Every tech is background-checked, uniformed, and named before arrival. And every estimate is free, including a free second opinion on any competitor’s written quote. We’re independently owned and operated under the Haven Standard, not a franchise, not a call center.
FAQs
No. As an independent Gelco service provider, we install Gelco OEM parts to manufacturer spec, which preserves any remaining warranty on the part itself. Gelco’s warranty covers manufacturing defects, not installation, so the key is using correct parts and proper mounting. We document both with photos and a written record. Call (331) 200-4445 if you want us to review your original purchase paperwork.
Most single-flue and multi-flue cap replacements are completed in 90 minutes to two hours on site, assuming the crown and flue tile are sound. If crown repair is needed, add two to four hours for curing time before remount. We book the full day if concrete work is involved, then return to mount the cap once the crown has set. You’ll know the schedule before we start - it’s in the written scope.
We can coat a crown with hairline cracks and minor spalling using CrownCoat or a similar elastomeric product, provided the structural concrete beneath is intact. If the crown is less than 2 inches thick at any point, has through-cracks, or sounds hollow when tapped, we recommend a full pour. The camera inspection shows us water intrusion below; the physical exam tells us crown integrity. We show you both and quote each option.
We stock common Gelco single-flue and multi-flue cap sizes in our regional warehouse, along with replacement mesh and base rings. Specialty sizes, custom widths, and Model C damper components typically ship in 5-7 business days. If your schedule is fixed, we quote an in-stock aftermarket equivalent from Olympia Chimney or Famco that matches Gelco’s gauge and mesh spec. You choose.
Gelco stamps a model number and “Made in USA” on the underside of the hood or on the mesh frame edge. If the stamp is rusted over or the cap is caked with creosote, we identify it by hood profile, mesh pattern, and mounting hardware spacing during the inspection. We’ve handled enough Gelco products in Hoffman Estates to recognize the line on sight. Call (331) 200-4445 and we’ll sort it out on the first visit.
