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.

AfterWhy New Rochelle Homeowners Choose HeatShield Chimney Cleaning
We provide New Rochelle Heatshield service - independent chimney cleaning, repair, and relining throughout New Rochelle, NY - no manufacturer affiliation, just hands-on experience with CeCure Sleeve, TherMix, and stainless liner systems installed in the city’s pre-WWII housing stock. Our sweeps carry genuine HeatShield-compatible parts and UL-listed equivalents on every truck, and most HeatShield jobs in New Rochelle finish in a single visit with upfront pricing agreed before we start. Call (516) 927-2678 to speak with a live person, any hour.
HeatShield lining systems are a specialty, not a sideline. We’ve installed and repaired hundreds of HeatShield-licensed stainless and cast-in-place liners across Westchester County, and we know exactly how their insulation wraps, T-sections, and top plates fail in real homes. That history is why New Rochelle homeowners call us for HeatShield work even though we’re an independent company with no manufacturer authorization.
New Rochelle sits directly on Long Island Sound, exposing chimneys to persistent salt-laden moisture and coastal wind that inland Westchester cities never face. This accelerates mortar joint erosion and brick spalling at a measurably faster rate. Combined with the city’s dense stock of pre-WWII masonry chimneys - particularly in the North End’s Victorian and Colonial Revival neighborhoods - New Rochelle homeowners face a genuinely more urgent annual inspection cycle than their inland neighbors. HeatShield liners were designed to protect exactly this kind of aging masonry, but only if they’re maintained, swept, and inspected before the coastal weather finds a gap.
We’re not HeatShield authorized. We’re better than that - we’re accountable. The 90-Day Done Right Promise governs every job: Krafted right, Every time, Your home first, Standing behind it. In writing, no arguing.
Why Trust Hearthstone Chimney Co. for Your HeatShield Chimney Cleaning?
Russell Haines learned this trade hands-on after completing a vocational program at Los Angeles Trade-Technical College, then put in years of real-world work before chimney cleaning became his full-time calling. He’s spent the better part of two decades running his brush through flues across Westchester County - including plenty of older Colonial-era stacks in New Rochelle’s Beechmont neighborhood, where the mortar tells stories the owners never knew. Russell is known for straightforward inspections. He tells you what needs doing, what can wait, and what was never a problem to begin with.
Our technicians are background-checked, uniformed, and trained specifically on HeatShield product architecture. They understand the difference between a CeCure Sleeve’s cast-in-place insulating liner and a TherMix refractory insulation system - and they know that sweeping either one incorrectly can damage the surface or leave creosote glaze hiding in the pour’s slight texture. We document every inspection with photos you can see and a plain-English verdict. No jargon, no scare tactics.
We stock genuine HeatShield liner components and matching fasteners on our trucks, plus equivalent UL-listed stainless or refractory parts for older systems where HeatShield-specific pieces are no longer manufactured. This matters in New Rochelle, where many CeCure and TherMix installations date to the 1990s and 2000s oil-to-gas conversions - conversions that were often done without proper relining, leaving oversized clay tile liners now venting high-efficiency gas units. Westchester County code and New Rochelle building inspectors flag these during point-of-sale inspections, making pre-listing HeatShield work a steady local demand. We know what inspectors look for because we’ve corrected it hundreds of times.
Calls are answered by a live person, 24 hours a day, 7 days a week. Not a voicemail, not a callback queue.
Common HeatShield Chimney Cleaning Problems We Fix in New Rochelle
- TherMix insulation cracking and separation. After years of creosote-glaze cycling, the cast-in-place refractory can develop hairline cracks that widen into gaps, exposing bare masonry to direct heat. In New Rochelle’s salt-air environment, this accelerates - moisture gets behind the insulation, freezes, and pushes it further from the flue wall. We catch this with Level-2 camera inspection. If the separation is localized, we can patch with compatible refractory; if it’s widespread, replacement is the honest call. Patching usually fails within a season once the bond is broken.
- Failed top plate caulk seams. HeatShield top plates rely on a flexible caulk seal between the plate and the flue tile or liner top. New Rochelle’s coastal sun and freeze-thaw cycles dry this caulk until it pulls away, creating a channel for rain to track down the outside of the liner and soak the smoke chamber. Homeowners notice a damp fireplace smell after storms, or visible water staining on the firebox walls. We replace the top plate assembly and reseal with fresh, compatible caulk rated for the local temperature swing.
- T-section and tee-cap misalignment in offsets. Many New Rochelle chimneys have built-in offsets to clear floor joists in their 1920s construction. HeatShield T-sections must align precisely so creosote sheds past the joint rather than piling up. Misalignment happens during original installation or shifts as the house settles. Creosote packs at the joint, restricting draft until smoke backs up into the room. We re-set the tee, verify alignment with a borescope, and test draft with a manometer before we leave.
- Liner-to-appliance connector corrosion at the damper or insert collar. Where a HeatShield liner meets an older firebox with a warped damper frame, the connection point sees constant thermal flex and condensation. In New Rochelle, salt air accelerates stainless corrosion at this joint. The collar cracks, or the fasteners seize and snap during service. We stock replacement collars and fasteners for common HeatShield diameters, and we’ll tell you honestly if the firebox itself is too far gone for a safe connection.
- Creosote glaze accumulation on CeCure Sleeve surfaces. The slightly textured surface of a cast-in-place CeCure liner can hold glazed creosote more tenaciously than smooth stainless. Standard wire brushing won’t touch it. We use rotary polypropylene whips and controlled mechanical action - never chain flails that could fracture the liner surface - followed by chemical treatment where the glaze is severe. Annual sweeping prevents the buildup that makes this work expensive.
HeatShield Parts & Our Repair-vs-Replace Approach
We use genuine HeatShield liner components and matching fasteners where they exist. When a HeatShield-specific piece is no longer made for an older system, we turn to equivalent UL-listed stainless or refractory parts - never builder-grade substitutes. Our trucks carry common HeatShield top plates, T-sections, insulation wraps, and connector collars, so most New Rochelle jobs don’t wait on parts.
If a HeatShield liner is intact, we clean and reseal rather than upsell a full reline. Once the insulation or top plate is compromised, patching usually fails within a season. A replacement section is the honest call, and we’ll show you the camera footage so you can see why. No recommendation without evidence you can verify yourself.

FAQs - HeatShield Chimney Cleaning Service in New Rochelle
No. We are an independent HeatShield service provider with no manufacturer affiliation. Our expertise comes from hands-on installation and repair of hundreds of HeatShield systems across Westchester County, not from a certification program. The 90-Day Done Right Promise covers our workmanship directly.
Yes, where they exist and are available. For older HeatShield systems where specific parts are no longer manufactured, we use equivalent UL-listed stainless or refractory components that meet the same safety standards. We never substitute builder-grade materials.
Most HeatShield cleaning, inspection, and minor repairs in New Rochelle finish in two to four hours. Full liner replacements or extensive TherMix repairs typically require a full day. We agree on scope and timing before booking, and most jobs complete in a single visit.
We service and install CeCure Sleeve cast-in-place liners, TherMix refractory insulation systems, stainless rigid and flex liner kits, and all associated top plates, caps, and connector hardware. If you’re unsure what system you have, we’ll identify it during inspection.

A standard HeatShield chimney sweep and Level-2 inspection in New Rochelle typically runs $275-$395, depending on flue length, accessibility, and creosote severity. HeatShield top plate replacement adds $180-$340. T-section realignment or connector collar replacement ranges $220-$450. Full CeCure or TherMix relines are quoted individually after inspection. Call (516) 927-2678 for an exact quote - estimates are free.
Yes, and it requires specific technique. CeCure and TherMix surfaces are slightly textured and can hold glazed creosote more tenaciously than smooth stainless. We use rotary polypropylene whips and controlled mechanical action - never chain flails that could fracture the liner - with chemical treatment where needed. Annual sweeping prevents the severe buildup that makes this work costly.
Signs of trouble include smoke backing into the room, a persistent damp fireplace smell after rain, visible cracks or flaking in the firebox, or unusually long kindling times to establish draft. The only certain way to know is a Level-2 camera inspection, which we document with photos you can see. Call (516) 927-2678 to schedule - estimates are free.
The top plate caulk has likely failed, allowing water to track between the liner and the masonry. Salt air in New Rochelle accelerates this. We replace the cap and top plate assembly, reseal with fresh compatible caulk, and verify the repair with a water test. Left unaddressed, moisture damages the smoke chamber and can corrode the liner connection below.
Glazed creosote on cast-in-place liners often requires chemical pretreatment to soften before mechanical removal. We apply this as part of our standard process when the borescope shows glazing. For stainless HeatShield liners, standard rotary sweeping usually suffices. The key is annual service before glaze hardens to the point where aggressive removal risks liner damage.
We can evaluate whether your existing HeatShield liner is properly sized and rated for the gas appliance you want. Many New Rochelle homes have oversized liners from prior oil-to-gas conversions that don’t meet current code for high-efficiency gas units. If the liner is wrong, we’ll show you the camera evidence and quote a properly sized replacement. No guesswork, no upsell without proof.
