HeatShield Chimney Liner & Rebuild Nationwide

HeatShield Chimney Liner & Rebuild in Staten Island: What to Know First

We provide independent HeatShield chimney liner and rebuild service across Staten Island, with most liner replacements and partial rebuilds completed in a single visit after our Level-2 camera inspection. As an independent HeatShield service provider, we carry OEM and quality aftermarket parts for the Cerfractory Flue Seal, CeCure Sleeve Relining, and Hybrid systems, and we quote upfront so the number on the estimate matches the number on the invoice. If the chimney’s sound, we’ll say so. If it isn’t, you’ll hear that too. This page is for Staten Island homeowners who already have a HeatShield product installed and need honest guidance on whether it can be repaired or needs replacement. Call (516) 613-3035 to speak with a live person, any hour.

How HeatShield Products Fail - and How We Fix Them

• Cerfractory Flue Seal cracking in Tottenville and Great Kills homes. The sprayed ceramic coating develops spider-web cracking after 15-20 years of Staten Island’s freeze-thaw cycles, especially where salt air from the Arthur Kill accelerates surface degradation. We grind back to sound substrate, apply fresh Cerfractory mix, and cure it to factory spec. Done right, and we stand behind it.
• CeCure Sleeve separation at the flue collar. The sleeve can pull away from the top plate when the original mechanical anchor was undersized for a tall Staten Island chimney stack. We re-anchor with upgraded stainless hardware and reseal the junction with HeatShield-compatible refractory cement.
• Hybrid system corrosion at the stainless-to-ceramic transition. The 316Ti stainless lower section meets the ceramic upper in a joint that traps condensation, particularly in South Shore homes with longer, cooler flue runs. We cut back to sound metal, fabricate a proper condensate drain slope, and rejoin with a custom transition piece.
• Cerfractory spalling in oil-to-gas conversions. Staten Island’s older homes in Westerleigh and Port Richmond often kept their original flue dimensions when switching to gas, leaving too-large a bore for the lower exhaust temperatures. The coating never fully cures and flakes away. We resize with a stainless insert or full CeCure Sleeve, depending on clearance.
• HeatShield warranty gaps from non-certified prior work. We’ve found three Staten Island homes this year where a previous installer used generic refractory cement instead of Cerfractory mix, voiding coverage. We document the original materials with photo evidence, quote OEM-correct repair, and provide warranty-safe installation records.

Our HeatShield Chimney Liner & Rebuild Process

1. 1
   Live answer and booking. A real person picks up at (516) 613-3035, 24 hours a day. We schedule a Level-2 camera inspection, not a sales visit.
2. 2
   Camera inspection and documentation. Our technician runs a high-resolution camera the full flue length, captures photos you can see on-site, and delivers a plain-English verdict: repair, reline, or rebuild.
3. 3
   Parts decision with full disclosure. We stock HeatShield OEM Cerfractory and CeCure components, plus DuraFlex and Gelco stainless alternatives when the original system is beyond salvage. You see the parts before we start.
4. 4
   Repair or rebuild with no-hassle upfront pricing. The estimate you approve is the invoice you pay. Background-checked, uniformed technicians complete most jobs in one visit.
5. 5
   Post-repair smoke and draft test. We verify proper draw with a smoke pellet and digital manometer, not a visual guess.
6. 6
   Written 90-Day Done Right Promise. In writing, no arguing. If it’s not right, we come back.

What HeatShield Chimney Liner & Rebuild Costs in Staten Island

Price moves with flue height, accessibility (steep Staten Island roofs add rigging time), and whether we find hidden masonry decay behind the firebox. We always photograph what we find and explain it before any work proceeds. Call (516) 613-3035 for a free estimate - estimates are free, and there’s no obligation.
