How HeatShield Products Fail - and How We Fix Them

• Cerfractory Foam liner resurfacing separates from the substrate. HeatShield’s CFM system is designed to restore clay flue liners by applying a ceramic refractory foam coating, but in Arlington Heights we see separation where the original clay was heavily spalled or moisture-saturated before application. The freeze-thaw cycles here, especially in homes near Lake Arlington where groundwater sits higher, accelerate delamination. We strip the failed coating, assess the clay beneath, and either reapply to sound substrate or pivot to a stainless steel liner if the clay is too far gone.
• JointShield gaps reopen at mortar joints. HeatShield’s JointShield product seals flue tile mortar joints, but thermal cycling in Arlington Heights’ zero-degree winters and 90-degree attic stacks causes the sealant to pull back from expansion-contraction stress. We see this most in the older colonials along Campbell Street where flues were built with lime mortar that never fully cured. Our fix: remove the compromised JointShield, re-point with compatible refractory mortar where the joint structure allows, or recommend a full liner replacement if the tile shift is structural.
• Cerfractory Foam develops pinholing from creosote acid attack. Class III creosote, the glazed, tar-like buildup common in Arlington Heights homes burning seasoned hardwood on slow burns, produces acidic condensation that etches the CFM surface over seasons. Pinholing isn’t cosmetic; it’s a path for flue gases to reach the masonry. We camera-map the damage, remove the affected CFM layer, and either reapply with improved draft conditions or specify a 316Ti stainless liner for severe cases.
• Smoke chamber parging fails where HeatShield was used as a stopgap. Some Arlington Heights contractors used HeatShield Cerfractory Foam to parge smoke chambers that really needed structural rebuilds, especially in 1960s and 1970s ranches near Rand Road. The foam can’t carry the thermal load of a poorly designed smoke chamber. We remove the foam, rebuild the smoke chamber to NFPA 211 slope requirements with proper refractory materials, and document the before-and-after with camera footage.
• HeatShield liner coatings crack above the damper in high-heat fireplaces. Factory-built fireplaces retrofitted with HeatShield CFM in Arlington Heights sometimes see cracking in the first 18 inches above the damper where radiant heat concentrates. This isn’t a product defect; it’s a mismatch between the coating’s rated temperature and the fireplace’s output. We replace the section with a stainless steel connector or specify a listed factory-built chimney system if the appliance demands it.

Our HeatShield Chimney Liner & Rebuild Process

   Parts decision: HeatShield OEM, quality aftermarket, or alternative brand. We source HeatShield-compatible materials through our Haven buying network alongside DuraFlex, Gelco, and other proven lines. We explain the trade-offs, cost differences, and warranty implications of each path.
4. 4
   Repair or rebuild execution with progress documentation. Our background-checked, uniformed technician completes the work with the assigned license number on record. We photograph critical stages and final condition.
5. 5
   Post-repair camera verification and draft test. We re-run the camera, verify liner integrity, and perform a smoke or draft test to confirm safe operation.

What HeatShield Chimney Liner & Rebuild Costs in Arlington Heights

Price moves with flue height, accessibility (steep roofs near Lake Arlington’s wind exposure add time), and whether the existing HeatShield product can be salvaged or must be fully removed. We don’t guess at price over the phone; we inspect, camera-document, and write it down. Call (331) 202-2419 for your free estimate.
