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 Southampton: What to Know First
We provide independent HeatShield chimney liner and rebuild service throughout Southampton, 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, while partial rebuilds start around $1,800. We are not affiliated with or authorized by HeatShield; we are an independent service provider who has worked on their systems in local homes for over two decades.
This page is for Southampton homeowners who already have a HeatShield liner or are considering one, and need straight answers about what fails, what it costs, and who can fix it right. Call us at (516) 619-2915 for a free estimate, or read on for the specifics.
How HeatShield Products Fail - and How We Fix Them
HeatShield builds several liner and coating systems, and each has its own failure pattern in Southampton’s coastal climate. Salt air accelerates corrosion at the top of the flue, and the freeze-thaw cycles we get from late November through March stress joints and coatings differently than inland installs. Here is what we see:
- Cerfractory Foam flaking in the UL-1777 listed spray systems. The foam layer can delaminate when the underlying clay tile has hairline cracks that flex with temperature swings. We see this most in the older colonials off Jobs Lane where the original flue was built with soft brick. Our fix: mechanical removal of the failed foam, joint repair with HeatShield’s own Joint Repair mix where the substrate is sound, or full stainless replacement when the tile is too far gone.
- Flue Free 2000 flexible liner crevice corrosion at the collar. The 316Ti alloy resists most acid attack, but the rolled collar where the liner meets the appliance adapter can trap condensation. In Southampton’s humid summers, we’ve found pinhole leaks starting at that collar after seven to ten years. We cut back to sound metal and install a factory collar, or upgrade to a heavier-gauge DuraFlex Pro if the damage has spread.
- HeatShield Cerfractory Crown coating cracking at the drip edge. The crown coating is not a liner, but it protects the liner system below. When applied too thin at the edge, water wicks in and freezes. We’ve re-coated dozens of these with the proper 1/4-inch build and added a formed drip edge that sheds water past the brick.
- Factory-built chimney chase pan failure hiding liner damage. The HeatShield liner itself may test fine while the galvanized chase pan above it rusts through and dumps water onto the top plate. We always inspect the chase pan during a liner evaluation; replacing the liner without fixing the pan is throwing money away.
- Improperly sized Flue Free inserts causing drafting problems. A 6-inch liner rammed into an 8-by-12 flue can work on paper but fails in practice, especially with the taller chimney stacks common in Southampton’s 1920s-era homes. We measure the actual appliance output and the effective flue height before specifying any liner diameter.
Our HeatShield Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, 24 hours a day. We book a Level-2 camera inspection with photos you can see.
- 2
Inspection and verdict. Our technician runs a camera the full length of the flue, documents every joint, crack, and corrosion point, and gives you a plain-English verdict on the spot. Russell Haines reviews every HeatShield evaluation personally.
- 3
Parts decision. We specify OEM HeatShield materials where the warranty is still active and the substrate allows. If the system is out of warranty or the damage is too extensive, we quote quality aftermarket alternatives from DuraFlex or Gelco with equivalent or better specs.
- 4
The repair. Background-checked, uniformed technicians complete most liner replacements and partial rebuilds in a single visit. We protect floors and furniture, and we clean up after ourselves.
- 5
Testing and documentation. Every liner job gets a smoke test or draft test before we leave. You get photos, a written report, and the 90-Day Done Right Promise in writing.
- 6
Follow-up. We call within two weeks to confirm everything is performing as expected. If it’s not right, we come back. No paperwork, no arguing.

Why Southampton Homeowners Call Hearthstone Chimney Co. for HeatShield Work
We’ve been sweeping and repairing chimneys in Southampton since long before most of the current liner brands were on the market. Russell Haines and our crew have worked on HeatShield systems in the village’s older homes and in the newer construction toward Shinnecock Hills, so we know which installs were done well and which were rushed.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. Nothing is recommended without evidence you can examine yourself. The 90-Day Done Right Promise backs every job in writing. If we install a liner and it does not perform, we make it right. Most jobs finish in one visit. A live person answers the phone every hour of every day. And because we work with DuraFlex, Gelco, and other professional-grade brands, we are not locked into one manufacturer’s solution when another fits your situation better.
A clean flue does the talking - you just need a warm fire to hear it.
FAQs
No, if the repair is done with OEM materials and methods. As an independent HeatShield service provider, we use factory-specified Cerfractory Foam and Joint Repair products when the original warranty period is still active. Using non-HeatShield materials on a warranted system can void coverage, which is why we verify warranty status before specifying parts.
Most joint repairs and partial resurfacing jobs take four to six hours. A full liner replacement typically takes one full day. We complete most jobs in a single visit, and we protect your home and clean up thoroughly before we leave.
Yes. HeatShield’s core Cerfractory materials have remained consistent, and we stock the Joint Repair mix, Resurfacing System components, and Flue Free adapter collars. For discontinued liner sizes, we can often fabricate a transition or upgrade to a compatible DuraFlex or Gelco system that meets the same UL-1777 standard.
The camera inspection tells the story. Localized joint gaps or surface spalling can be repaired. If the underlying clay tile is shifting, if corrosion has eaten through the stainless collar, or if the liner has pulled away from the top plate, replacement is the sound choice. We show you the footage and explain which category you’re in. Call (516) 619-2915 for a free estimate.
HeatShield joint gaps and liner corrosion do not heal themselves. In Southampton’s climate, water intrusion through a failed crown or chase pan accelerates damage every winter. A compromised liner can allow carbon monoxide into living spaces or permit creosote to reach combustible framing. The inspection is free, and we’ll tell you honestly if the work can safely wait.
