How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Flue Liner - thermal shock cracking in freeze-thaw cycles. The cerfractory coating expands and contracts with every heating season, and Downers Grove’s hard swings from sub-zero January nights to 70-degree March days stress it more than southern climates. We find hairline fractures that open under load but seal when cold. Our fix: camera-scan mapping of every crack, then either targeted cerfractory patch (for cracks under 1/8 inch that don’t penetrate to substrate) or full relining recommendation with written photo evidence. We source HeatShield-compatible cerfractory mix through our Haven buying network, not generic refractory cement that voids the liner’s thermal rating.
• HeatShield UL Listed Chimney Relining System - smoke chamber parging failure above the damper. The UL listed system’s smoke chamber seal is often thinnest where heat concentrates, right at the throat. In Downers Grove homes built 1960-1990, we’ve found the original masons left corbelled brick that creates turbulence; the HeatShield parging erodes there first. We re-parge with HeatShield-compatible mixture rated to 2900°F, or recommend a stainless liner insert if the corbelling is too deep for stable adhesion. The camera shows you the erosion pattern before we quote.
• HeatShield Gas Fireplace Inserts - failed pilot assemblies in vented units. The Robertshaw and SIT pilot systems used in HeatShield’s earlier vented insert lines collect condensate in Downers Grove’s humid shoulder seasons when the unit sits idle. The pilot orifice corrodes, not the thermocouple - a misdiagnosis we see from techs who swap the thermocouple twice before checking orifice bore diameter. We clean, gauge, and replace with OEM or cross-referenced SIT valve assemblies from our Famco supply chain, with the part number written on your invoice.
• HeatShield Wood Burning Fireplaces - cracked refractory panels in the firebox. The factory refractory panels in HeatShield’s wood burning units are 1.25-inch cast refractory, not true firebrick. After 8-12 seasons of Downers Grove oak and hickory burns, they spider-web at the rear panel where radiant heat concentrates. We stock HeatShield-compatible 1.25-inch panels through Olympia Chimney’s catalog, or source Gelco refractory if the unit is discontinued. We never shim generic 1-inch panels - the air gap behind them accelerates steel wrapper corrosion.
• HeatShield Fireplace Dampers - rust-seized throat dampers in pre-fab metal chimneys. HeatShield’s metal chimney systems use galvanized throat dampers that seize when creosote condenses on the blade in shoulder season. Downers Grove’s lake-effect humidity makes this worse than inland Illinois. We free the mechanism, assess blade pitting with the camera, and replace with Gelco or HeatShield-compatible stainless dampers if pitting exceeds 1/16 inch. A seized damper left forced-open costs you 8-12% in heating loss through the flue - we measure that with a smoke pencil and show you the reading.

Our HeatShield Fireplace Services Process

1. 1
   Call and schedule. A live person answers 24/7. We ask your HeatShield model number (on the metal tag inside the firebox or on the chimney exterior), fuel type, and what’s happening. We give you a two-hour arrival window and text when your tech is en route - Clause 3 of the Haven Standard, “Arrive on schedule.”
2. 2
   NFPA 211 Level 2 inspection with camera. We run a chimney camera the full flue length, photograph the firebox, damper, smoke chamber, and exterior termination. Corrine Halstead and her crew have done this on every job since 2009. You see the footage before we name a price.
3. 3
   Written estimate with parts specified. We list OEM versus quality aftermarket options (DuraFlex, Gelco, or HeatShield-direct) with part numbers, warranty terms, and why we’re recommending one over the other. The price is the price. Clause 1 of the Haven Standard - “Have it in writing.”
4. 4
   Repair or conversion with photo documentation. Your assigned tech performs the work, pressure-tests gas lines where applicable, and runs a final camera pass to verify the fix. We photograph before, during, and after.
5. 5
   Written warranty and archived record. You receive a printed scope, invoice, and 365-Day Done Right Promise certificate. Your photo record is archived under Haven Standard Clause 4 - available if you sell the home or need warranty service.
6. 6
   Follow-up at 90 days. We call to confirm performance, especially on HeatShield liner repairs where thermal cycling completes its first full season.

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

We’ve inspected and cleaned more than 38,000 chimneys since 2009, every one with a camera record and a written price first. The 365-Day Done Right Promise covers every HeatShield repair we make - if the pilot drifts, the panel cracks, or the parging fails, we make it right. Our techs are background-checked, uniformed, and assigned by name; you get a text when they’re on the way, not a four-hour window and a stranger.

We’re not locked to one brand. Our Haven buying network sources DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield alongside HeatShield-compatible parts, so we recommend what’s right for your unit and budget, not what our warehouse happens to stock. In Downers Grove, that matters - the older masonry fireplaces near Main Street and the 1990s prefabs in the north subdivisions need different approaches, and we carry both.

The camera does not lie, and neither does the written price.
