How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam liner systems with corroded caps. The stainless outer shell on early Cerfractory installations can trap moisture against the cap seam when Fairfield’s coastal humidity sits heavy in July and August. We see this especially in homes within a mile of Long Island Sound. We pull the cap, inspect the liner termination for foam degradation, and install a vented replacement cap that lets the assembly breathe.
• HeatShield UL-listed reline jobs with improperly sized aftermarket caps. A cap too small for a reline diameter creates a downdraft trap that accelerates crown spalling. We measure the reline OD precisely and source caps with proper clearance, either HeatShield-compatible or from our Gelco and Olympia Chimney inventory when the OEM lead time stretches past burning season.
• ThermalTech pre-cast crowns with hairline fractures. Fairfield’s freeze-thaw cycles are brutal on rigid crown materials. ThermalTech’s original formulation can spider-crack where the flue meets the crown slab. We clean to bare concrete, apply HeatShield’s CrownCoat flexible membrane, and tool the edges so water sheets off rather than pools.
• Multi-flue HeatShield systems with missing or damaged flue caps. One missing cap on a two-flue setup funnels rain directly onto the uncapped flue, ruining the liner below. We inventory multi-flue caps in common HeatShield dimensions and can match a single replacement without ordering a full set from the factory.
• Cerfractory smooth-wall liners with cap-related creosote buildup. The slick interior sheds creosote downward, but a poorly vented cap can create a cold spot at the top that reverses the effect. We see this in Greenfield Hill colonials with tall exterior chimneys exposed to northwest winter winds. Our fix: a properly spec’d cap plus a Level-2 camera inspection to confirm the liner wall is clean above the smoke chamber.

Our HeatShield Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, notes your HeatShield system if you know it, and books a window that works. No app, no callback queue.
2. 2
   Level-2 camera inspection. Our tech arrives uniformed and background-checked, runs a camera the full length, and photographs the cap, crown, and liner termination. You see the images on the spot.
3. 3
   Plain-English verdict and upfront pricing. We tell you what’s wrong, what we recommend, and what it costs. If the work can safely wait, we say so. The estimate number is the invoice number.
4. 4
   Parts decision: OEM or quality aftermarket. For common HeatShield cap sizes, we stock compatible units from Gelco and Olympia Chimney. For warranty-sensitive Cerfractory terminations, we source factory-spec parts and document the installation for your records.
5. 5
   The repair and test. We complete cap installation, crown coating, or full crown rebuild, then run a draft test and final camera pass to confirm proper termination and seal.
6. 6
   Cleanup, documentation, and guarantee. We leave the work area clean, provide photos and a written report, and activate your 90-Day Done Right Promise. If it’s not right, we don’t leave - and if we missed something, we come back with no paperwork and no arguing.
