How HeatShield Products Fail - and How We Fix Them

• HeatShield Cerfractory Foam liner systems with corroded caps: The stainless outer cap on older Cerfractory installs can pit where salt-laden White Plains winter air meets exhaust condensation. We see this most on homes within a mile of the Bronx River Parkway corridor. We don’t just swap the cap; we inspect the foam collar beneath for delamination, then fit a 304-grade replacement with a proper storm collar, not a universal clamp-on that’ll leak in two seasons.
• HeatShield UL-listed multi-flue caps with sagging lids: The 24″ and 30″ multi-flue models carry more snow load than single-flue units, and after a decade the lid support welds can crack. We’ve replaced lids that fell two inches onto the flue terminals, blocking draft. Our fix: either OEM lid replacement if the frame is sound, or a full Gelco or Famco frame upgrade when the base has warped.
• HeatShield crown coating over original poured crowns: The HeatShield crown sealant is good material, but it’s often applied too thin over active cracks. Water gets behind it, freezes, and pushes the coating off in sheets. In White Plains, where we average 25 freeze-thaw cycles per winter, we grind out the crack to 1/4″, fill with hydraulic cement, then apply the coating at the specified 1/8″ minimum with fiberglass mesh reinforcement.
• HeatShield factory-built chimney caps with separated storm collars: The slip-fit storm collar on factory-built caps can work loose where thermal expansion meets the flue pipe. We’ve found gaps on 15-year-old installs that were dumping water directly onto the crown. We reseat with high-temp silicone and add a secondary compression band on HeatShield models where the original design runs short.
• HeatShield custom copper caps with solder joint failure: The custom line is beautiful but the soldered seams at the lid corners can crack after years of summer expansion and winter contraction. White Plains’ temperature swing from July to January averages 80 degrees, and that movement adds up. We resolder with 95/5 tin-silver, not lead, and add a relief crease at the stress point so it doesn’t repeat.

Our HeatShield Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, checks our White Plains route, and books a window. We’ll ask whether you know your HeatShield model or when it was installed.
2. 2
   Level-2 camera inspection on arrival. Our tech photographs the cap, crown, and flue interior. You see the images on a tablet while we explain what we’re looking at. No surprises, no “trust me.”
3. 3
   Parts decision with options. If your HeatShield cap is discontinued or the lead time is unreasonable, we’ll show you a quality aftermarket alternative from Gelco or Famco that fits without modifying the flue. We explain OEM versus aftermarket trade-offs, including warranty implications, and you decide.
4. 4
   The repair. Background-checked, uniformed techs complete most HeatShield cap and crown jobs in one visit. Crown work gets a controlled cure time; we don’t rush it.
5. 5
   Post-repair verification. We run a draft test and final camera pass to confirm the flue draws properly and nothing obstructs the opening. Photos go in your file.
6. 6
   Written guarantee and cleanup. The 90-Day Done Right Promise goes in writing before we leave. The number on the estimate is the number on the invoice.

Why White Plains 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 homeowners in White Plains - especially the ones who’ve owned their house long enough to replace a roof already - don’t want a sales pitch. They want someone who knows the difference between a HeatShield Cerfractory collar and a standard slip-in, who carries DuraFlex and Gelco backup parts when HeatShield lead times stretch, and who puts the 90-Day Done Right Promise in writing with no arguing if something isn’t right. Russell Haines and our crew have worked on chimneys from the Gedney Farm colonials to the mid-century splits off North Street. Most jobs finish in one visit. The estimate matches the invoice. If the chimney’s doing its job, you won’t think about it. That’s exactly where we want to leave things.
