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 Cap & Crown in Southampton: What to Know First
As an independent HeatShield service provider, Hearthstone Chimney Co. installs, repairs, and replaces HeatShield chimney caps and crowns throughout Southampton. Most HeatShield cap and crown jobs are completed in a single visit after our Level-2 camera inspection, with upfront pricing agreed before any work begins. We do not upsell liners or masonry rebuilds unless the camera shows you clear evidence it is needed.
This page is for Southampton homeowners who already have HeatShield components on their chimney and need honest answers about what is failing, what it will cost, and who can fix it without the runaround. Call (516) 619-2915 any time, day or night. A live person answers.
How HeatShield Products Fail - and How We Fix Them
- HeatShield Cerfractory Foam liner systems with factory-installed caps: The cap collar can separate from the foam body where Southampton’s salt air meets freeze-thaw cycling. We see this most on homes within a mile of the bay. We remove the failed collar, reseat with HeatShield-compatible refractory sealant, and install a Gelco or Famco cap with an independent mounting bracket so the repair outlasts the original design.
- HeatShield Pro-Form multi-flue caps on pre-fab chimneys: The stamped steel base pan rusts through at the weld seams after 7-10 years, sooner if pine needles collect in the valleys. Water drips straight onto the crown below, accelerating concrete spalling. We replace with a Copperfield stainless multi-flue cap, sealed at the perimeter, and inspect the crown for hidden saturation with our camera.
- HeatShield crown coatings over original poured crowns: The coating delaminates when applied over a crown that was not properly profiled for drainage. Southampton’s driving northeast rains exploit any low spot. We grind the crown to a proper slope, apply a bonding primer, then recoat with HeatShield Cerfractory Foam or switch to a poured concrete rebuild if the substrate is too far gone.
- HeatShield UL-listed chase covers on factory-built chimneys: The galvanized edge flashing corrodes where it meets the siding, especially on cedar-shingled homes common north of Montauk Highway. Water tracks behind the siding and rots the chase framing. We fabricate custom Copperfield aluminum or stainless chase covers with integrated drip edges, counter-flashed correctly.
- HeatShield draft-inducing caps on vented fireplaces: The bimetallic strip that opens the secondary air intake seizes after seasons of disuse, common in Southampton’s seasonal homes. The fireplace smokes on startup or fails to draw. We free the mechanism, replace the strip if cracked, and verify draft performance with a smoke pencil before we leave.
Our HeatShield Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, 24/7. We book a window that works for you. No deposit required.
- 2
Level-2 camera inspection. Our technician documents the cap, crown, and flue interior with photos you can see on the spot. We explain what is wrong in plain English, no jargon.
- 3
Parts decision. If HeatShield OEM is available and makes sense for your system, we order it. If lead time is long or the design has a known flaw, we recommend a quality aftermarket alternative from DuraFlex, Gelco, or Famco and tell you exactly why.
- 4
Repair or replacement. Background-checked, uniformed technicians complete most jobs in one visit. We protect your roof and landscaping. The price we quoted is the price on the invoice.
- 5
Post-job test and documentation. We run a final camera pass, verify cap clearance and draft, and leave you with photos and a written report. The 90-Day Done Right Promise applies automatically, in writing, no paperwork to file.
- 6
Cleanup and close. We haul away old material. You get a clean flue and a cap that sheds water the way it should. A clean flue does the talking - you just need a warm fire to hear it.

Why Southampton Homeowners Call Hearthstone Chimney Co. for HeatShield Work
We have cleaned and inspected chimneys throughout Southampton Village, including plenty of the older shingled colonials along Jobs Lane, long enough to know which problems show up after a hard winter and which ones were overdue before the first frost. Russell Haines and our crew diagnose HeatShield systems correctly the first time because we have worked on them since the product line was new to the market.
Our 90-Day Done Right Promise means if it is not right, we come back. No arguing, no forms to chase down. We answer the phone with a live person every hour of every day. Our technicians are background-checked and uniformed, and they carry DuraFlex, Gelco, and Famco parts so you are not held hostage by a single brand’s supply chain. Done right, and we stand behind it.
FAQs
No, independent service does not void your HeatShield warranty as long as compatible materials and proper procedures are used. We document our work with photos and part numbers so any future warranty claim is supported, not undermined.
We source HeatShield OEM when it is the right choice and available within a reasonable timeframe. When a known design flaw exists or lead time stretches past burning season, we recommend quality aftermarket caps from Gelco or Famco and explain the trade-off before you decide.
We determine that with our camera inspection and a hammer test. Surface hairline cracks and minor spalling take coating. Deep cracks, exposed rebar, or a crown that sounds hollow when tapped needs rebuild. We show you the photos and let you choose.
Most single-flue replacements take 90 minutes to two hours from ladder set to final photo. Multi-flue caps or chase covers may run half a day if custom fabrication is needed. We tell you the expected duration before we start.
Not usually. A leaking cap lets water damage the crown and flue interior, but the liner itself may be sound. We camera the full flue before recommending any liner work. If the liner is intact, fixing the cap and crown is the right repair. Call (516) 619-2915 for a free inspection and an honest verdict.
