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.

How HeatShield Products Fail - and How We Fix Them
- HeatShield Cerfractory Foam liner systems crack at the smoke shelf in New Rochelle’s older Beechmont and Wykagyl Colonials, where freeze-thaw cycles work the refractory against the original brick. The foam separates from the wall, creating a gap that channels heat into surrounding masonry. We remove the failed section, re-apply with HeatShield’s specified bonding wash, and verify with a camera pull before we sign off.
- HeatShield UL-listed gas inserts lose ignition reliability in the 21st-century series with sealed combustion chambers. The ceramic igniter degrades faster than the control board suggests, especially when homeowners run short cycles that never reach full operating temperature. We test resistance at the igniter, clean the flame sensor with a proper media, and replace only the part that’s actually failed, not the entire assembly.
- HeatShield wood-burning fireboxes spall at the rear wall where the throat meets the smoke chamber. This is the Cerfractory slurry’s known weak point: it handles direct flame well but thermal shock from rapid starts after long idle periods causes surface flaking. We grind to sound substrate, apply a compatible resurfacing mix, and cure per HeatShield’s temperature protocol, not a generic fast-dry.
- HeatShield damper hardware seizes in coastal-humidity New Rochelle, particularly on conversion units installed in the 1990s with original cast-iron throat dampers. The pivot pin corrodes where the factory coating wore thin. We can free, re-bush, and re-coat a salvageable damper, or fit a quality aftermarket replacement from Gelco or Famco if the casting is cracked.
- HeatShield fireplace conversion gaskets degrade unevenly around the glass door frame, creating a false draft that pulls room air up the flue even when the unit is “off.” Homeowners notice it as a cold spot or phantom draft. We measure the gap, source the correct density gasket for that series, and set the door to factory torque spec so the seal holds.
Our HeatShield Fireplace Services Process
- 1
Call and schedule. A live person answers at (516) 927-2678, any hour. We ask the model series if you know it, the symptoms, and when you last had service.
- 2
Arrival and inspection. Our uniformed technician arrives in a marked van, lays protection, and runs a Level-2 camera inspection. You see the photos on the tablet as we pull the camera back. Russell Haines trained our team to narrate what we’re seeing, not bury findings in a report you read later.
- 3
Diagnosis and parts decision. We identify whether your HeatShield component needs OEM replacement, quality aftermarket from our DuraFlex or Gelco inventory, or repair in place. We explain the trade-off, including warranty considerations, and give you one written price.
- 4
The repair. Most HeatShield fireplace services finish in one visit. We use professional-grade materials, work to manufacturer-compatible spec, and test every function before we pack tools.
- 5
Documentation and guarantee. You get photos, a plain-English verdict, and our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork to find, no arguing.
- 6
Cleanup and close. We haul away old parts, vacuum the hearth area, and leave the work zone cleaner than we found it.

Why New Rochelle Homeowners Call Hearthstone Chimney Co. for HeatShield Work
We’ve been sweeping and repairing chimneys across Westchester County for over 42 years, and we’ve watched HeatShield products move from niche retrofit to common equipment in New Rochelle homes. That history matters when a 1990s conversion unit needs service and the original manual is long gone. We document every inspection with photos you can see and a plain-English verdict. Our 90-Day Done Right Promise is in writing, no arguing. Our technicians are background-checked, uniformed, and carry the multi-brand inventory, DuraFlex, Gelco, HeatShield, Olympia Chimney, Famco, and Copperfield, to finish most jobs in a single visit. And when you call (516) 927-2678, a live person answers, every day, every hour. Tell me what’s burning, and I’ll tell you what’s wrong.
FAQs
No, using an independent HeatShield service provider does not automatically void your warranty, though warranty coverage for parts typically requires OEM replacement and documentation of proper installation. We keep serial numbers, photo records, and spec sheets so any future warranty claim has the paper trail it needs. Call (516) 927-2678 if you’d like us to review your warranty status before we start.
Most HeatShield fireplace repairs are completed in a single visit of two to four hours. Cerfractory liner restorations need a controlled cure time, so we schedule those with a return verification pull the next day. We tell you the timeline before we book, not after we’re in your living room. Call (516) 927-2678 to schedule.
We stock common HeatShield service parts and maintain supplier relationships for discontinued series. For obsolete components, we evaluate whether a quality aftermarket part from Gelco, Famco, or DuraFlex meets the application without compromising safety. We never install a substitute without explaining the trade-off and getting your written approval.
We make that call with a camera inspection and a plain-English verdict, not a sales pitch. Surface spalling or minor cracking usually qualifies for Cerfractory resurfacing. Structural compromise, multiple through-cracks, or failed previous repairs may mean replacement is the honest recommendation. You see the photos. You decide. Call (516) 927-2678 for a free estimate.
Gas HeatShield fireplaces need annual inspection and cleaning of the burner, pilot, and venting path. Wood-burning units with Cerfractory liners should be swept and inspected after every cord of wood burned, or annually, whichever comes first. In New Rochelle, where coastal humidity accelerates damper and hardware corrosion, we recommend a pre-season check even if use was light the prior year. Call (516) 927-2678 to book your $89 seasonal tune-up.
