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 Repair in New Rochelle: What to Know First
We provide independent HeatShield chimney repair in New Rochelle, with most jobs completed in a single visit and no-hassle upfront pricing agreed before we start. A typical HeatShield repair runs between $280 and $950 depending on the scope, and we back every job with our 90-Day Done Right Promise in writing. This page is for homeowners who already have HeatShield products installed and need honest answers about what’s failing, what it costs, and who can fix it without voiding whatever warranty coverage remains. Call (516) 927-2678 and a live person will pick up, any hour of any day.
How HeatShield Products Fail - and How We Fix Them
- Cerfractory Foam Resurfacing (CFR) liner panels delaminate from freeze-thaw cycling. New Rochelle’s coastal position means more freeze-thaw cycles than inland Westchester, and CFR panels applied too thin in the original install start bubbling or flaking where they meet the smoke chamber. We remove the compromised layer, prep the substrate with HeatShield’s specified bonding agent, and reapply to OEM thickness. We’ve found this in several homes near Glen Island Park where the nor’easter exposure accelerates the cycle.
- HeatShield UL Listed relining sleeves separate at the seam in high-heat appliances. The sleeve system works well in standard fireplaces, but when paired with older wood stoves or inserts that run hotter than spec, the longitudinal seam can gap. We diagnose this with our Level-2 camera, determine if the sleeve is salvageable, and either re-seam with HeatShield-compatible refractory adhesive or recommend a DuraFlex stainless liner if the appliance output exceeds the sleeve’s rating.
- Smoke chamber parging cracks where the original application missed a corner. HeatShield’s smoke chamber sealant needs full contact with masonry; any dry spot becomes a stress riser. In New Rochelle’s pre-war housing stock, especially the 1920s colonials in Beechmont, irregular firebox geometry makes this more common. We cut back to sound material and re-parge, feathering the edges so heat distributes evenly.
- CrownSeal top coating alligators within five years on south-facing chimneys. The elastomeric coating UV-degrades faster when it bakes all afternoon. We strip the failed CrownSeal, repair the underlying crown structure with proper pitch and drip edge, then reapply or switch to a Gelco multi-layer system if the thermal exposure is severe.
- FlueGard inspection port gaskets harden and leak combustion air. The rubber gasket on HeatShield’s cleanout and inspection ports wasn’t designed for four decades of ozone and salt air. We replace with OEM-spec gaskets where available, or machine a compatible silicone substitute that outlasts the original in marine-adjacent climates like ours.
Our HeatShield Chimney Repair Process
- 1
Call and schedule. A live person answers, checks our availability, and books your appointment. No app, no callback queue.
- 2
Level-2 camera inspection. Our technician runs a camera the full length of the flue and smoke chamber, documents every finding with photos you can see on the spot, and delivers a plain-English verdict on what’s wrong, what can wait, and what was never a problem.
- 3
Parts decision. We verify whether your HeatShield component is still under any original warranty, source OEM replacement materials when it preserves coverage, and use quality aftermarket equivalents from our Copperfield and Famco supply chain when OEM is discontinued or the cost is unreasonable. We explain the trade-off before you decide.
- 4
Repair and test. The technician completes the work, pressure-tests or smoke-tests as appropriate for the component, and verifies clearances and draft performance.
- 5
Documentation and guarantee. You receive photos of the completed repair, a written invoice matching the upfront estimate exactly, and our 90-Day Done Right Promise in writing. If it’s not right, we come back. No paperwork to find, no argument.
- 6
Cleanup and close. We leave the work area as we found it, answer any questions, and you’re back to normal.

Why New Rochelle Homeowners Call Hearthstone Chimney Co. for HeatShield Work
We’ve been sweeping and repairing chimneys in Westchester County for over 42 years, and Russell Haines has spent the better part of two decades running his brush through flues here, including plenty of older Colonial-era stacks in New Rochelle’s Beechmont neighborhood where the mortar tells stories the owners never knew. We know HeatShield products because we’ve serviced them since they first appeared in local homes, and we carry DuraFlex and Gelco alternatives when a HeatShield component isn’t the right fix. Our 90-Day Done Right Promise is in writing with no arguing. Technicians are background-checked, uniformed, and trained to explain what they found without selling what you don’t need. A square deal, no surprises on the bill. That’s why people who’ve been burned by contractors before tend to stay with us.
FAQs
It depends on who does the work and what parts they use. As an independent HeatShield service provider, we source OEM materials when they preserve any remaining warranty coverage, and we document the parts used so you have a record. Call (516) 927-2678 and we’ll check your install date and product line against HeatShield’s warranty terms.
Most repairs are completed in a single visit of two to four hours. Relining sleeve replacements or extensive smoke chamber work may require a second day if the refractory material needs cure time. We tell you before we start.
We stock common HeatShield consumables and gaskets through our Famco and Copperfield supply chain. Discontinued liner sizes or specialty refractory mixes may take three to five business days. We never start a job without confirming parts in hand.
The camera tells the story. Surface delamination or isolated seam gaps usually repair well. Widespread cracking, multiple seam failures, or evidence of improper original sizing mean replacement, often with a DuraFlex stainless liner that outlasts the original application. We show you the footage and explain both paths.
A compromised HeatShield liner or smoke chamber seal allows heat and combustion gases into surrounding masonry, accelerating deterioration and raising fire risk. That said, we also tell you plainly when a condition can wait until after burning season. Nothing is recommended without camera evidence you can see for yourself. Call (516) 927-2678 for a free inspection and an honest timeline.
