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.
Gelco Chimney Repair in Hoffman Estates: What to Know First
We provide independent Gelco chimney repair in Hoffman Estates, with most jobs inspected within 48 hours and priced in writing before any work starts. Typical Gelco repairs run $450 to $2,800 depending on whether we’re repointing mortar, rebuilding a spalling crown, or replacing compromised flashing. We are not affiliated with Gelco; we are an independent service provider who sources Gelco-compatible materials through our Haven buying network and documents every flue with a camera scan before quoting.
This page is for Hoffman Estates homeowners who already know they have Gelco components in their chimney system, or whose home inspector flagged a Gelco cap, liner, or flashing assembly that needs attention. If you’re near the Barrington Road corridor or in one of the subdivisions built during the 2015-2020 boom, we’ve likely already worked on your exact model series. Call (331) 200-4445 to book a Level 2 inspection or bring us a competitor’s written estimate for a free second opinion.
How Gelco Products Fail - and How We Fix Them
- Gelco Ultra-Pro chimney caps: The stainless mesh on Ultra-Pro caps installed around 2016-2019 tends to separate at the weld seam after three to four freeze-thaw cycles in Hoffman Estates. We see this most often in homes west of Roselle Road where wind exposure accelerates metal fatigue. Our fix: remove the cap, assess the flue tile underneath for spalling, and install a new Gelco-compatible cap with an expanded mesh gauge or step up to a Famco equivalent if the chase width allows.
- Gelco pre-fab chimney chase covers: The galvanized steel chase covers on Gelco pre-fab systems rust through at the center sump faster than the manufacturer spec suggests, especially when pine needle debris sits through our wet springs. We replace with a Gelco-spec stainless chase cover or a copper upgrade, and we always photo-document the chase framing for rot before sealing it back up.
- Gelco flexible flue liners: The Gelco ProFlex liner, common in Hoffman Estates gas conversions from 2017-2021, can develop creosote bridging at the flex joints when homeowners burn improperly seasoned wood. We run a camera to locate the exact joint, then determine whether a mechanical sweep resolves it or the liner section needs replacement with a DuraFlex equivalent that handles condensing appliances better.
- Gelco mortar and crown wash: Gelco’s proprietary crown wash formulation shrinks more than traditional Portland-based mixes in our climate zone. After three winters in Hoffman Estates, we regularly find hairline cracks that have widened to water intrusion points. We grind back to sound concrete, apply a HeatShield CrownCoat or rebuild with a custom-poured crown, depending on what the camera shows in the flue below.
- Gelco step and counter flashing: The aluminum step flashing on Gelco systems fatigues at the 90-degree bend where it meets Hoffman Estates’ common dimensional shingles. We remove the compromised flashing, inspect the roof deck for saturation, and install new copper or lead-coated copper flashing integrated with the existing roofing - never caulk-over, which is what we find half the time on competitor “repairs.”
Our Gelco Chimney Repair Process

- 1
Call and schedule. A live person answers, checks Corrine’s or a named tech’s availability, and texts you when we’re en route. No voicemail, no web-form black hole.
- 2
Level 2 inspection with camera. We run a camera down the flue, photograph the crown, cap, flashing, and any visible Gelco labeling or model stamps. Clause 4 of the Haven Standard requires this photo record on every job - we’ve done it since 2009.
- 3
Written price and scope. We deliver a flat price, a written scope of work, and a written warranty before any tools come out. If Gelco OEM parts are back-ordered, we quote the quality aftermarket equivalent and explain the trade-off.
- 4
Repair with documented steps. Techs photo each stage: the opened chase, the removed component, the new installation, the water test. You see what we saw.
- 5
Final scan and sign-off. Camera goes back down to confirm flue integrity post-repair. We hand you the written warranty, the photo record, and the 365-Day Done Right Promise stamped on every job.
- 6
Archive and follow-up. Your record goes into our files - Corrine still keeps service records in a three-ring binder because her handwriting is better than any app she’s tried - and we call at 11 months if a sweep is due.

Why Hoffman Estates Homeowners Call Level Two Chimney Hoffman Estates for Gelco Work

We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and a growing share of our Hoffman Estates calls involve Gelco components from the 2015-2020 build wave. Our techs carry Gelco-compatible parts alongside DuraFlex liners and HeatShield refractory materials, so we’re not waiting on a single-source supply chain while your flue sits open.
The 365-Day Done Right Promise covers every repair we make. If a crown wash cracks or a flashing seam opens in year one, we return and make it right. Background-checked, uniformed technicians arrive with license numbers visible, and you get a text when we’re on the way. Camera first, price second, pen third - in that order every time.
Corrine Halstead grew up in Queens, picked up her first wire brush at Queensborough Community College, and has spent the better part of fifteen years running inspections across the northwest suburbs. She comes off a Hoffman Estates roof with camera footage, a written condition report, and a flat price - in that order - before anyone signs anything.
FAQs
No, using an independent service provider for repair work does not automatically void Gelco’s product warranty, though Gelco may require proof that OEM-spec parts were used for any component replacement. We document part numbers and source materials through our Haven buying network so you have that record if a warranty claim arises. Call (331) 200-4445 if you need help interpreting your specific Gelco warranty terms.
Most Gelco repairs in Hoffman Estates are completed in one working day: mortar repointing, cap replacement, and standard flashing work all fall in this window. Crown rebuilds or partial rebuilds may require a second day for proper cure time. We never rush a cure or a water test. Call (331) 200-4445 to check current scheduling.
Replace only when the flue liner is compromised beyond spot repair, the chimney structure shows lateral movement, or repair costs exceed 60% of replacement. We make that determination with camera evidence you can see, not a sales pitch. Many Gelco systems we inspect in Hoffman Estates need targeted repair, not full replacement. Call (331) 200-4445 for a camera inspection and honest assessment.
We source both Gelco OEM and quality aftermarket equivalents through our Haven buying network. If Gelco OEM is back-ordered - which we’ve seen on Ultra-Pro mesh assemblies - we quote a Famco or Olympia Chimney equivalent with equivalent or better specs, and we explain the difference in writing before you decide. Call (331) 200-4445 to discuss part availability for your specific model.
Deferred repair on a Gelco chimney in Hoffman Estates typically leads to water intrusion through crown cracks, accelerated spalling from freeze-thaw, and eventual liner damage that turns a $600 repointing job into a $2,500 rebuild. Carbon monoxide risk rises if the flue liner degrades. We show you exactly what we found and whether it can wait a season - no scare tactics, just the camera footage. Call (331) 200-4445 for a free inspection and written priority assessment.
