How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam liner systems with cracked or missing crowns. The foam liner shrinks slightly as it cures, which can stress the crown mortar above it. In Denver’s freeze-thaw cycles, that stress opens hairline cracks that channel water straight onto the foam surface. We remove the damaged crown section, re-pour with high-early-strength concrete rated for Colorado’s temperature swings, and seal with a silicone-based crown coat that flexes without cracking.
• HeatShield UL-Listed stainless caps with seized mounting hardware. The 304-grade stainless used in HeatShield’s standard cap line holds up well to Denver’s UV, but the zinc-plated through-bolts that ship with many units corrode solid within 4-6 years of mountain snow and road salt exposure. We drill out the seized fasteners, install 316-grade stainless hardware with anti-seize compound, and torque to HeatShield’s spec so the next removal doesn’t require an angle grinder.
• Multi-flue HeatShield caps with improper overhang on Denver’s older masonry. HeatShield’s multi-flue caps come in standard depths that don’t always cover the full crown projection on 1920s-1950s Denver bungalows. Water runs off the cap edge and soaks the exposed crown lip, causing spalling - the flaking you see on brick faces. We measure crown overhang against NFPA 211 clearance requirements and either source a custom-depth HeatShield-compatible cap or fabricate a stainless drip edge extension in our shop.
• Cerfractory Foam jobs where the original installer skipped the top-seal termination. HeatShield’s installation manual calls for a refractory top-seal where the foam meets the flue tile or metal collar. Some Denver-area installers from the 2010-2018 rush skipped this step to save time. Without that seal, combustion gases condense in the cap cavity during cold snaps, accelerating corrosion of the cap’s interior baffles. We pull the cap, camera-scan the termination, apply the missing top-seal with HeatShield’s specified refractory mix, and reinstall with new gaskets.
• HeatShield cap mesh clogged with cottonwood seed and Denver’s fine concrete dust. The 5/8-inch spark arrestor mesh that ships standard on most HeatShield caps is the right size for ember containment but traps debris from Denver’s prolific cottonwood stands and post-construction dust. We clean the mesh in place when possible, replace it when the weld joints have corroded through, and can upsize to 3/4-inch mesh where local code allows and fire risk is low - always documented in your photo record.

Our HeatShield Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, checks our calendar, and books your arrival window. You get a text when your tech is en route.
2. 2
   NFPA 211 Level 2 inspection with camera. We run the camera down the flue to inspect the liner condition, check the crown for delamination or spalling, and photograph the cap from the roof and the firebox looking up. Clause 4 of the Haven Standard requires this photo record on every job - we’ve done it since 2009.
3. 3
   Written price and scope before any work. Your tech shows you the footage, names the problem, and hands you a written price with parts specified: OEM HeatShield, quality aftermarket equivalent, or fabricated custom. You approve before we start.
4. 4
   Repair or replacement. We match the parts to what we found - never more, never less. Crown repairs get proper cure time; cap replacements get 316-grade hardware and anti-seize.
5. 5
   Post-work camera verification and documentation. We re-run the camera to confirm clearances and cap fit, photograph the completed work from roof and ground, and upload everything to your record.
6. 6
   365-Day Done Right Promise in writing. If it’s not done right, we make it right. The warranty terms are on the invoice before you pay.

Why Denver Homeowners Call Level Two Chimney Denver for HeatShield Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of Denver’s housing stock from the 2015-2020 build wave has HeatShield systems coming due for first cap and crown service. Our techs carry HeatShield parts in the truck, but we’re also stocked with DuraFlex and Gelco equivalents when the OEM part is backordered or the homeowner prefers an upgrade. The camera doesn’t guess. Neither do we. Corrine Halstead trained on combustion venting and liner systems at Apex Technical School in Manhattan before bringing that documentation-first habit to Denver, and she still shows customers their own camera footage rather than summarizing it. Every job gets a written price, a written scope, and a written warranty before anyone touches a tool - Haven Standard Clause 1. If you’re staring at a competitor’s quote and it doesn’t feel right, our Free Second Opinion is exactly that: free, and in writing.
