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.
HeatShield Chimney Cap & Crown in Hoffman Estates: What to Know First
We provide independent HeatShield chimney cap and crown service in Hoffman Estates, typically scheduling within a week and completing most jobs in a single visit. A written price lands before any work starts, and every job carries our 365-Day Done Right Promise under the Haven Standard.
This page is for Hoffman Estates homeowners who already have a HeatShield system installed and need cap or crown work done right. Maybe your cap blew off in a March wind off the Barrington Road corridor, or your crown is shedding flakes into the flue. Either way, you need someone who knows HeatShield’s specific lines and won’t treat your chimney like a generic brick column. Call us at (331) 200-4445 for a free estimate, or read on for the details we wish every customer knew before hiring.
How HeatShield Products Fail - and How We Fix Them
- HeatShield Cerfractory Foam liner systems with factory-installed stainless caps - The cap collar on early Cerfractory Foam jobs (pre-2018) was welded with a lower-grade seam that cracks at the weld line after five to seven winters of Hoffman Estates freeze-thaw. We see this most in homes north of I-90 where roof pitch and wind exposure accelerate metal fatigue. Our fix: remove the failed cap, inspect the flue collar for creosote intrusion, and install a replacement cap with a continuous rolled collar, not a welded seam. We document the crack with camera footage before touching anything.
- HeatShield ProLiner multi-flue caps in salt-exposed installations - The ProLiner’s standard 304 stainless cap holds up well inland, but homes within two miles of the tollway salt spray corridor show accelerated pitting at the mesh base. The mesh isn’t the problem; the base flange where salt collects is. We upgrade to a 316L marine-grade cap from our Haven buying network, or source direct HeatShield OEM if the homeowner prefers. Either way, we show you both options in writing with the price difference before you choose.
- HeatShield crown coating delamination on poured crowns - HeatShield’s crown resurfacing product bonds well to clean concrete, but we regularly find it applied over crowns that were power-washed and never fully dried, especially in shaded Hoffman Estates lots with mature oak canopy. The coating lifts in sheets after two seasons. Our fix: moisture meter the crown, let it hit 15% or below, then reapply with a bonding agent specified for damp climates. We time-lapse the drying with photos; Clause 4 of the Haven Standard requires the record.
- HeatShield UL-listed caps with undersized mesh in homes burning cured hardwood - The factory mesh on some HeatShield cap lines is 5/8-inch, which clogs with Class III creosote, a hard, tar-like deposit from slow-burning fires common in Hoffman Estates basements with older draft systems. Clogged mesh backs up smoke and CO. We replace with 3/4-inch mesh or install a top-sealing damper cap hybrid, depending on what the camera shows in the flue. We also tell you if your burning habits are causing the clog, not the cap.
- HeatShield factory chase covers on manufactured chimneys - The stamped steel chase covers on some HeatShield prefab systems pool water at the corners where the cross-break is shallow. In Hoffman Estates, where spring rain follows freeze-thaw, that water finds the chase top and rots the framing. We fabricate a replacement with a deeper cross-break and extended drip edge, or source a HeatShield-compatible Gelco cover through our buying network. The camera goes down the chase first; we’ve found collapsed framing hidden by a cover that looked fine from the ground.
Our HeatShield Chimney Cap & Crown Process

- 1
Call and schedule. A live person answers, day or night. We ask for your HeatShield model if you know it, your address in Hoffman Estates, and what you’re seeing. We book a window and text you when the tech is en route.
- 2
NFPA 211 Level 2 inspection with camera. Corrine Halstead or one of our background-checked, uniformed techs runs a camera down the flue, photographs the crown or cap from the roof, and moisture-meters any concrete. You get the footage on a tablet before we discuss price. Camera first, price second, pen third - in that order every time.
- 3
Written scope and price. We deliver a flat price, a written description of the work, and the warranty terms before anyone picks up a tool. If we find additional issues, we show you the camera evidence and a revised price; nothing happens without your initials.
- 4
Parts decision: OEM or quality aftermarket. For HeatShield systems, we stock common cap sizes and crown coating materials through our Haven buying network. If you want genuine HeatShield OEM, we order it and reschedule. Most homeowners choose our 316L or Gelco-equivalent options; we explain the trade-off in warranty coverage and price.
- 5
Repair and test. We complete the cap installation, crown coating, or chase cover replacement, then run a final camera pass and draft test. The photo record updates automatically.
- 6
Documentation and follow-up. You receive a written completion report with photos, warranty registration if applicable, and our 365-Day Done Right Promise in writing. We call at 30 days to confirm no leaks or draft issues.

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

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of our Hoffman Estates calls involve HeatShield systems installed in the 2015-2020 new-construction boom. Corrine Halstead, who picked up her first wire brush at Queensborough Community College before moving to the northwest suburbs, has spent fifteen years refining what a proper inspection looks like: camera footage, a written condition report, and a flat price before anyone signs.
Our techs carry HeatShield-compatible parts from DuraFlex, Gelco, Olympia Chimney, and Famco through our Haven buying network, so you’re not waiting two weeks for a backordered OEM cap while water enters your flue. If we find your HeatShield liner also needs attention, we handle it in the same visit with the same written-price protocol. The 365-Day Done Right Promise applies to everything we touch, and our Free Second Opinion policy means you can bring us any competitor’s written estimate for comparison.
We are an independent HeatShield service provider, not affiliated with or authorized by the manufacturer. We service HeatShield products because we know them, not because we’re told to.
FAQs
Installing a non-OEM cap typically does not void the liner warranty, but using an incompatible crown coating can. We check your HeatShield warranty terms before recommending materials, and we’ll source OEM if you prefer. Call (331) 200-4445 and we’ll review your specific warranty status during the free estimate.
Most single-flue cap replacements in Hoffman Estates take two to three hours from ladder set to final photo. Multi-flue caps or chase cover jobs run four to six hours. We book enough time to do it once and do it right; rushing a crown coating before the concrete is dry is how delamination happens.
If the crown has surface cracks and the concrete is sound, we resurface with a HeatShield-compatible coating after proper drying. If the crown is spalling, cracked through, or separating from the brick, we rebuild. The camera and moisture meter tell us which; we show you the evidence before quoting either option.
We stock common HeatShield cap sizes and crown coating materials. Uncommon sizes or genuine OEM requests may add three to five business days for ordering. We tell you before booking, not after arrival.
NFPA 211 recommends annual inspection for all chimney systems, and we agree for Hoffman Estates homes given our freeze-thaw cycles and hardwood burning patterns. The cap and crown take the worst weather; catching a cracked cap in October beats discovering it after January ice has entered the flue. Call (331) 200-4445 to schedule; estimates are free.
