This page is for homeowners who already have a HeatShield liner, crown wash, or refractory product in their chimney and need it fixed right. Maybe you’re seeing fresh cracks after last winter’s freeze-thaw cycles, or your sweep flagged something during the annual inspection. Either way, you’ll get photos you can see, a plain-English verdict, and a written 90-Day Done Right Promise. Call (301) 215-3355 anytime - a live person answers, 24 hours a day.

How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam liner resurfacing separates from clay flue tiles when the original prep work missed glazed creosote or the foam was applied too thin in the smoke chamber transition. In Westminster’s older farmhouses along Route 140, we see this where oil-to-gas conversions left uneven surfaces. We grind back to sound substrate, re-apply to OEM thickness, and verify with a pull-through camera before the job is closed.
• HeatShield CrownSeal flexible crown coating develops alligator cracking after five to seven years when applied over a crown that was already structurally compromised, not rebuilt first. Carroll County’s wet springs and hard freezes accelerate this. We don’t just re-coat - we cut out spalled concrete, re-pour or re-trowel the crown, then apply CrownSeal as a protective layer, not a structural bandage.
• HeatShield FireGuard joint repair system fails at mortar joints that were ground too shallow or where the applicator missed a hidden lateral crack running behind the flue tile. Westminster chimneys venting woodstoves - common in the rural pockets near Union Mills - see this from thermal shock. We open the joint to proper depth, inspect with a lateral camera, and pack FireGuard to full specification so the repair survives the next heating season.
• HeatShield Sleeve relining system shows condensation staining at the collar connection when the top plate wasn’t sealed with high-temp silicone or the wrong termination cap was used. Our fix: pull the collar, inspect for sleeve ovality, re-seal with OEM-spec materials, and install a proper vented cap that matches the appliance’s BTU output.
• HeatShield Premium Refractory mortar in smoke chamber parging shrinks and dusts when mixed too wet during humid summer installs - a mistake we’ve corrected on Westminster jobs done by others in July and August humidity. We re-prep the chamber, mix to manufacturer’s viscosity for conditions, and tool the finish so it keys properly to the firebrick.

Our HeatShield Chimney Repair Process

1. 1
   Call and schedule. A live person answers (301) 215-3355, 24/7. We book a window, confirm the address in Westminster or nearby, and note any symptoms you’ve observed.
2. 2
   Level-2 camera inspection. Our technician arrives uniformed and background-checked. We run a video scan from firebox to cap, document every crack, joint, and defect with photos you can see on the spot, and deliver a plain-English verdict - no jargon, no scare tactics.
3. 3
   Parts decision. We specify HeatShield OEM materials when the repair must match existing product chemistry for warranty compatibility. Where an independent fix is appropriate and a quality aftermarket alternative from DuraFlex or Gelco meets spec, we’ll tell you plainly and price both options.
4. 4
   Upfront pricing, then repair. You get one number before we start. No surprises on the bill. Most HeatShield repairs are completed in a single visit - repointing, crown restoration, joint repair, or collar resealing.
5. 5
   Post-repair verification. We camera the repair, pressure-test or smoke-test where applicable, and show you the result. The work is documented with photos for your records.
6. 6
   Written guarantee. The 90-Day Done Right Promise goes in your hand before we leave. If it’s not right, we make it right - no paperwork, no arguing.

Why Westminster Homeowners Call Hearthstone Chimney Co. for HeatShield Work

We’ve been answering the phone with a live person for over 42 years, and we’ve learned that the homeowners who call us back are the ones who got a square deal the first time. Our 90-Day Done Right Promise is in writing with no arguing - Krafted right, Every time, Your home first, Standing behind it. That’s the K.E.Y.S. code, and it governs every HeatShield job we touch.

Russell Haines learned the trade at Los Angeles Trade-Technical College, but it’s the older homes along Westminster’s Main Street corridor where he’s spent years doing the kind of chimney work that keeps families safe through a Carroll County winter. Our technicians are background-checked, uniformed, and trained on HeatShield’s specific product lines - not generic “chimney repair” that treats every liner the same. When a HeatShield part is back-ordered or discontinued, we draw on our experience with DuraFlex and Gelco systems to specify a compatible alternative that doesn’t compromise safety.

Do it right the first time, or plan on doing it twice. That’s the standard we hold ourselves to on every Westminster job.
