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.
HeatShield Chimney Liner & Rebuild in Huntington: What to Know First
We provide independent HeatShield chimney liner & rebuild service in Huntington, with most jobs completed in a single visit and upfront pricing agreed before we start. A typical HeatShield liner replacement runs $2,800-$4,500 depending on flue height and condition, and we always inspect with a camera first so you see what we see. This page is for Huntington homeowners who already have a HeatShield liner or are considering one, and want straight answers about when it can be saved, when it needs replacing, and what it actually costs. Call (631) 776-4075 anytime - a live person answers, 24 hours a day.
How HeatShield Products Fail - and How We Fix Them
- Cerfractory Foam liner resurfacing (HeatShield’s UL-listed spray system) - In Huntington’s freeze-thaw climate, especially in homes near the harbor where salt air accelerates corrosion, we’ve seen the foam layer separate from clay tile substrates after 8-12 years. The surface looks intact from the firebox, but camera inspection reveals delamination starting at the smoke shelf. We remove the failed coating and install a stainless steel liner, or reapply only if the underlying clay is structurally sound.
- HeatShield Joint Repair system - This is the mortar-joint repair kit, and it fails predictably in Huntington’s older homes with offset flues, like those clustered around West Neck Road and Cold Spring Harbor. The rigid application can’t flex where the flue shifts, so cracks reopen within two heating seasons. We don’t patch again. We sleeve the flue with a flexible DuraFlex liner that moves with the chimney.
- ProForm liner (HeatShield’s poured refractory system) - We’ve found voids and shrinkage cracks in ProForm installs where the pour was rushed or the chimney had excessive water intrusion from a failed crown. In Huntington, with our heavy nor’easter rainfall, water entry is common. The fix is partial rebuild of the crown and smoke chamber, then a new liner system sized to the appliance.
- Factory-built metal chimney with HeatShield components - The transition collars and listed adapters corrode at the seam where they meet the fireplace insert, particularly in homes burning green or unseasoned cordwood from local suppliers. We replace with OEM-spec or compatible aftermarket parts from Copperfield, pressure-test the assembly, and document the connection with photos.
- HeatShield stainless flex liners (earlier generation, pre-2015) - These had lighter-gauge walls (0.005″ in some residential runs) that don’t hold up to the acidic condensate from modern EPA-certified stoves. We’ve pulled collapsed sections from chimneys in South Huntington where the liner looked fine from below but had pinholed above the roofline. We replace with current-spec DuraFlex or Gelco 316Ti stainless in the proper gauge for the fuel type.
Our HeatShield Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, 24/7. We book a Level-2 camera inspection with photo documentation.
- 2
Inspection and verdict. Our technician runs a camera the full length of the flue, photographs every defect, and explains what you’re seeing in plain English. Russell Haines reviews every HeatShield assessment personally - he’s seen enough of these systems to know which ones are worth saving and which aren’t.
- 3
Parts decision. If the HeatShield component is still manufactured, we quote OEM. If it’s discontinued or the design was flawed, we specify quality aftermarket from DuraFlex, Gelco, or Olympia Chimney - never builder-grade substitutes. You see the part numbers and warranty terms before we order.
- 4
The repair. Background-checked, uniformed technicians complete most HeatShield liner replacements and rebuilds in a single day. We protect your floors, work with the fireplace cold, and clean up after.
- 5
Testing and documentation. We pressure-test or smoke-test every liner installation, depending on fuel type. You get photos, a written report, and the 90-Day Done Right Promise in writing - if it’s not right, we come back, no arguing.
- 6
Follow-up. We call within two weeks to confirm performance. A clean chimney isn’t a luxury - it’s just the job done right.

FAQs
No, if the work is performed using OEM-spec parts and practices - but HeatShield’s warranty does not cover labor, only materials, and it requires documentation of proper installation. As an independent HeatShield service provider, we document every step with photos and written reports so any future warranty claim has the paperwork it needs. Call (631) 776-4075 and we’ll review your specific warranty status.
Some HeatShield components from the early 2000s are discontinued, but we source compatible aftermarket parts from DuraFlex, Gelco, and Olympia Chimney that meet or exceed UL 1777 listing requirements. We never install a part we can’t stand behind. If your system is obsolete, we’ll tell you plainly and price a full replacement.
Localized joint gaps or minor spalling in a structurally sound clay flue often justify repair. Multiple cracks, delamination, or corrosion in the metal itself means replacement. We make that call with camera evidence you can see, not a sales pitch. Sometimes the honest answer is that nothing needs doing yet - we’ll tell you that too.
Most residential HeatShield liner replacements in Huntington are completed in one day. Complex jobs - tall flues in historic homes, or rebuilds requiring scaffolding - may run two days. We give you a firm schedule at booking, not a window.
A compromised liner allows heat, smoke, and carbon monoxide to reach combustible framing. In Huntington’s older homes with balloon framing, that risk is real and serious. Creosote also leaks through gaps and builds where you can’t see it. We don’t scare-sell - we show you the camera footage and let you decide. But we won’t pretend a failed liner is fine. Call (631) 776-4075 for a free inspection.
