Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterHeatShield Chimney Cap & Crown in New Rochelle: What to Know First
We provide independent HeatShield chimney cap and crown service in New Rochelle, with most jobs completed in a single visit and upfront pricing agreed before we start. A standard HeatShield cap replacement or crown coating runs $280 to $620 depending on the series and flue configuration, and we carry common HeatShield parts so you’re not waiting on a warehouse shipment. This page is for homeowners who already have a HeatShield system installed and need cap or crown work done correctly without upsell pressure. If you’re seeing rust streaks, water in the firebox, or a crown that’s cracking at the edges, call us at (516) 927-2678. We’ll look at it, show you photos, and tell you what actually needs doing.
How HeatShield Products Fail - and How We Fix Them
- HeatShield Cerfractory Foam liners with Gelco base caps: The Gelco cap collar can loosen where it meets the foam liner top in New Rochelle’s freeze-thaw cycles. Water gets in, freezes, and pushes the collar outward. We remove the collar, reseat it with high-temp silicone rated for the Cerfractory interface, and add a drip edge the original install often skips.
- HeatShield UL-Listed stainless caps (single-flue, standard mesh): The 304-grade mesh on early-series units corrodes from the inside out when homeowners burn unseasoned hardwood, which is common in Beechmont and Wykagyl where oak and maple are plentiful. The mesh looks fine from the ground but is paper-thin at the flue gas line. We replace with 316-grade mesh, which HeatShield later switched to, and document the before condition so you see why.
- HeatShield crown coatings over existing concrete crowns: The coating fails at the crown’s edge where it meets the brick, not in the center. New Rochelle’s coastal humidity keeps the crown edge damp longer than inland climates, so the bond line breaks first. We grind back two inches past the visible crack, apply a bonding agent, and rebuild the edge with CrownCoat or a compatible refractory before the HeatShield top coat goes on.
- Multi-flue HeatShield caps with integrated spark arrestors: The arrestor frame welds crack at the corner joints after 8-12 years, especially on north-facing chimneys that stay colder and cycle more. We can field-repair minor cracks or source a replacement frame that matches the existing base flange, saving you the cost of a full cap assembly when the hood and mesh are still sound.
- HeatShield custom copper caps (older high-end installs in Shore Road and Bonnie Crest): The copper develops pinholes at the solder joints where acid rain from the I-95 corridor collects in the cap’s low points. We solder-patch when the damage is localized, or fabricate a replacement cap to the same footprint if the original is too far gone. We keep the patina matched so the repair doesn’t shout from the street.
Our HeatShield Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask what you’re seeing, when the HeatShield system was installed if you know, and whether you’ve had previous cap or crown work.
- 2
Level-2 camera inspection. Our tech runs a camera up the flue and across the crown surface. You get photos on a tablet and a plain-English verdict: what’s failing, why, and what can wait.
- 3
Parts decision. We check HeatShield OEM availability against quality aftermarket options from our DuraFlex and Gelco inventory. If OEM is back-ordered or discontinued for your series, we explain the trade-off and warranty implication before you decide.
- 4
Upfront pricing and sign-off. The number on the estimate is the number on the invoice. No surprises, no add-ons discovered mid-job.
- 5
The repair. Background-checked, uniformed techs complete most HeatShield cap and crown jobs in a single visit. We test-fit, seal, and run a final camera pass to confirm the flue is clear and the cap seats correctly.
- 6
Documentation and guarantee. You get photos of the completed work, a written report, and our 90-Day Done Right Promise. If it’s not right, we make it right. In writing, no arguing.

Why New Rochelle Homeowners Call Hearthstone Chimney Co. for HeatShield Work
We’ve been sweeping and repairing chimneys in New Rochelle for over 42 years. Russell Haines has run his brush through flues in this town long enough to know which HeatShield installs were done in the 2005-2012 window when certain cap collars were underspecified. Our 90-Day Done Right Promise means if the repair fails, we come back. In writing, no arguing. We carry DuraFlex and Gelco parts as backup when HeatShield OEM is unavailable, so you’re not held hostage by a brand’s supply chain. And a live person answers the phone, every hour of every day. Done right, and we stand behind it.
FAQs
No, provided the work is done to manufacturer specifications and documented properly. As an independent HeatShield service provider, we follow HeatShield’s installation guidelines for cap and crown work, use compatible materials, and photograph every step so you have records if a warranty question ever arises. Call (516) 927-2678 if you want us to review your original warranty terms before we start.
Most single-flue replacements take 90 minutes to two hours from ladder set to final photo. Multi-flue caps or jobs requiring crown edge rebuild add another hour. We complete most HeatShield cap and crown work in one visit because we stock common parts. You’ll know the time estimate before we begin.
Often yes. We cross-reference the original HeatShield part number against our DuraFlex and Gelco inventory, and we can fabricate custom flanges when needed. If an exact match isn’t possible, we show you the closest equivalent and explain any functional difference before you decide. No surprises on the bill.
We run a camera and tap-test the crown surface. Hairline cracks with solid substrate get a HeatShield-compatible coating with edge reinforcement. Spalling, exposed aggregate, or a crown that’s separated from the brick course means rebuild. We show you the photos and tell you which category you’re in. Some crowns can wait a season; others shouldn’t. We’ll say which.
Look for rust streaks on the chimney face, water in the firebox after rain, or gaps where the cap meets the flue tile. Do not climb the roof to inspect the crown yourself. The fall risk isn’t worth it, and from the ground you can’t assess crown condition accurately. If you see any of the three signs above, call us at (516) 927-2678 for a camera inspection.
