We provide HeatShield in New York City with independent chimney restoration service across Manhattan, specializing in Cerfractory foam sealant relining and crown repair for the borough’s pre-war boiler flues and century-old fireplace systems.

Call (833) 349-5892 for a free estimate; most Manhattan appointments are available within 48 hours.
Why Manhattan Residents Choose Us for HeatShield Service
Paul Torres leads every job personally. Fourteen years in the trade, over 1,100 reviews, and he’s still the one climbing the ladder — not a subcontractor you’ve never met.
Manhattan’s chimney landscape is unlike anywhere else we work. The pre-war apartment buildings dominating the borough — those brick stacks rising ten, fifteen stories above West End Avenue or Gramercy Park — weren’t built for modern gas boilers. When NYC’s Local Law 38 forced the phase-out of heavy heating oils, thousands of buildings converted to cleaner fuels without resizing their flues. Oversized boiler flues condense moisture. Moisture destroys liners. That’s where HeatShield’s Cerfractory technology earns its keep, and it’s why we’ve trained specifically in its application.
Paul grew up in the Bronx watching his uncle do finish carpentry. He learned early that honest hands-on work builds a real reputation — “I’ll tell you what I see, not what sounds good.” After HVAC and building systems training at Bronx Community College, he fell into chimney work through a neighbor who needed reliable hands and never looked back. From the sweep to the rebuild, we handle it. Professional-grade materials, properly installed: DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, Copperfield. No big-box substitutions.
Common HeatShield Chimney Cleaning Problems We Solve in Manhattan
- Condensation-induced liner deterioration in converted boiler flues. Manhattan’s pre-war buildings — especially those 1920s co-ops along West End Avenue — were designed for #4 or #6 oil combustion. Post-Local Law 38 gas conversions left flues too large for the lower exhaust temperatures. Moisture condenses on terracotta, spalling accelerates, and the liner crumbles. We apply HeatShield Cerfractory foam sealant to restore a smooth, insulated surface that handles modern gas exhaust properly.
- Spalling mortar joints on rooftop crowns exposed to freeze-thaw cycles. Manhattan’s winter temperature swings — often 40 degrees in a single day — plus wind-driven moisture off the Hudson and East Rivers, destroy crown mortar. We’ve inspected crowns on fifteen-story stacks in Hell’s Kitchen where the top course was literally missing. HeatShield Crown Repair System seals and waterproofs without a full rebuild.
- Cracked terracotta flue tiles in brownstone fireplaces. Those 1890s row houses in the East Village still have original terracotta liners — now 130+ years old. Heat-damaged, cracked, or shifted tiles create gaps where combustion gases escape into party walls. HeatShield foam sealant fills these voids and creates a continuous new flue surface without demolition.
- Leaking flashing where Hudson wind drives rain under roof interfaces. West-facing chimneys above the 70s catch the worst of it. Water penetrates at the roof-to-chimney joint, rusting out fireboxes and damaging adjacent framing. HeatShield flashing repair with integrated waterproofing stops the leak at its source.
- Co-op board rejection of undocumented “cleaning” receipts. Manhattan co-op and condo boards — particularly in Gramercy Park and pre-war buildings throughout the borough — require written inspection letters before approving fireplace operation. Our Level 2 Inspection reports include the documentation boards actually accept, calibrated to NYC DOB standards.
HeatShield Service in Manhattan: What Local Conditions Mean for Your Equipment
Here’s something you won’t find on a generic chimney service page: Manhattan’s 311 reporting system maintains specific complaint codes for smokestack and boiler flue emissions. When a neighbor calls in visible exhaust or odor, the Department of Buildings can flag your building for inspection. Our cleaning and inspection reports are structured to satisfy DOB requirements from the start — including Certificate of Inspection (Form 20) when your chimney is part of a boiler compliance filing. This isn’t paperwork for paperwork’s sake. We’ve seen supers in Chinatown scramble to produce acceptable documentation after a 311 complaint triggered a violation notice — one reason we offer HeatShield service in Chinatown with full compliance documentation from the start. The cleaning matters. The documentation matters just as much in Manhattan’s regulatory environment. We deliver both, formatted for NYC’s specific compliance framework.
That West End Avenue call — 1928 co-op, gas-converted boiler, rust staining the lobby ceiling — started with a super who’d already had two other sweeps in. Neither could explain why the moisture kept returning. Our Level 2 inspection found the cracked terracotta liner at the fifth-floor level, right where the flue jogged around a structural beam. HeatShield Cerfractory foam sealant reline. Passed DOB boiler inspection the following week. Problem solved because we looked past the symptom.

FAQs — HeatShield Chimney Cleaning in Manhattan
We’re an independent service provider specializing in HeatShield systems, not a manufacturer-authorized dealer. We’ve completed hundreds of HeatShield installations across Manhattan’s pre-war buildings and train continuously in Cerfractory sealant application techniques. Our independence means we recommend HeatShield where it’s the right solution — and we’ll tell you when a different approach makes more sense. Call (833) 349-5892 to discuss your specific flue condition.
Yes — when properly applied. HeatShield Cerfractory foam sealant is specifically engineered to navigate offset flues and maintain adhesion on irregular surfaces. Manhattan’s pre-war chimneys often jog around structural beams between floors; our applicator equipment and technique accommodate these bends. We’ve relined flues with two and three offsets that passed Level 2 camera inspection clean. The key is thorough pre-cleaning and proper cure time, which we build into every Manhattan schedule.
Most Manhattan co-op and condo boards accept properly documented HeatShield relining as a permanent repair, provided the work includes a Level 2 inspection report and — where applicable — DOB-compliant certification. We format our documentation specifically for board review, including pre- and post-repair camera footage. For boiler flue work, we provide Certificate of Inspection (Form 20) when required. We’ve yet to have a board reject our HeatShield documentation — though we always recommend checking your building’s specific alteration agreement before proceeding.
Local Law 38 and subsequent rules forced the conversion from #4 and #6 heating oil to cleaner fuels, leaving oversized flues prone to condensation damage that wasn’t a problem with hotter oil exhaust. If your building converted and hasn’t had a post-conversion inspection, you’re likely overdue. Annual inspection is prudent for converted boiler flues; we recommend scheduling before heating season when Manhattan sweeps book solid. Call (833) 349-5892 — we still have September and October openings.
Absolutely — and you need specific expertise for these. Pre-war brownstone fireplaces often have deteriorated original liners, shifted terracotta, or improper venting for modern gas inserts. We inspect for adequate draft, proper liner sizing, and safe clearances to combustibles. Many Manhattan brownstone inserts were installed without proper chimney evaluation; we find the problems the original installer missed. Gas fireplace service with full chimney inspection runs $350–$550; call for availability.
That’s most of our Manhattan work. Boiler flue cleaning and inspection — particularly for gas-converted systems in pre-war buildings — is critical for safe operation and DOB compliance. We clean, inspect, and document boiler flues throughout Manhattan, with reports formatted for super and board requirements. No fireplace needed. Call (833) 349-5892 for building-specific scheduling.
