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.

AfterFast, Reliable Chimney Liner & Rebuild Across St. George
Chimney liner and rebuild work in St. George, NY typically runs $2,800-$8,500 depending on whether you’re replacing a failed liner or rebuilding a salt-damaged stack, and most projects are completed in a single visit after our Level-2 inspection. If you live on the north-facing harbor slope, your chimney faces salt-laden air and wind-driven moisture that inland Staten Island neighborhoods simply don’t see, which means galvanized caps and crowns fail years faster here and unlined coal-era flues present real safety issues under NYC Department of Buildings standards. We’re Hearthstone Chimney Co., and we’ve been dispatching crews to St. George from our New York City office for decades - call (516) 613-3035 to speak with a live person, any hour, any day.
Why Hearthstone Chimney Co. Is St. George’s Preferred Chimney Liner & Rebuild Company
We’ve worked on chimneys along Bay Street, up the Richmond Terrace corridor, and through the attached row house blocks near the ferry terminal long enough to know what fails here and in what order. St. George homeowners don’t need a sales pitch - they need someone who recognizes a coal-era thimble connection before it becomes a carbon monoxide problem, and who documents every finding with photos and a plain-English verdict.
Our Chimney Liner & Rebuild team arrives background-checked and uniformed, completes most jobs in one visit, and prices everything upfront so the estimate matches the invoice. The 90-Day Done Right Promise governs every liner and rebuild we do in St. George: in writing, no arguing, no paperwork chase. If it’s not right, we make it right. We’ve operated this way for over 42 years, and we plan to be answering the phone here in thirty more.
Our Chimney Liner & Rebuild Services in St. George
Stainless Steel Liner Installation
St. George’s harbor exposure destroys galvanized metal in a few seasons. That’s why we specify stainless steel liners - DuraFlex and Olympia Chimney components - for every coastal installation we do near the waterfront grid. A stainless liner handles the acidic condensate from modern oil and gas appliances while standing up to the salt air that reaches up the flue from a failed cap or crown. Typical stainless liner installation in St. George runs $2,800-$4,200 for a standard heating-appliance flue, including the inspection, photos you can see, and our written verdict.
Flexible Liner Systems
The tight, offset flues in St. George’s late-Victorian row houses often won’t accept a rigid liner without extensive demolition. Flexible DuraFlex liners navigate these bends without tearing out fireplace surrounds or opening walls. We’ve run flexible liners through chimneys on St. Mark’s Place and along Hamilton Avenue where rigid pipe would have meant a much larger job. Flexible systems in this market typically fall between $3,200-$5,000 when offsets or multiple appliances complicate the run.
Liner Replacement
Clay tile liners in St. George’s older housing stock crack from thermal shock and freeze-thaw cycling, especially once harbor moisture finds its way down through a compromised crown. We remove the failed liner - or the original unlined brick - and install a new system sized correctly for your appliance, not the coal boiler that was here in 1890. Liner replacement in St. George averages $3,500-$6,500 depending on flue height, access, and whether the thimble connection needs reworking to meet current NYC DOB clearance rules.
Partial Chimney Rebuild
When the top courses of a St. George stack have spalled brick faces and eroded mortar joints from repeated freeze-thaw, a partial rebuild restores structural integrity without the cost of tearing down to the roofline. We rebuild with matching brick where possible, pour a new concrete crown with proper overhang and drip edge, and reflash with copper or stainless to survive the next nor’easter. Partial rebuilds in St. George typically range $4,500-$8,500, with harbor-facing stacks on the north slope trending toward the higher end due to accelerated deterioration.

Trusted Brands We Service in St. George
We don’t use builder-grade substitutes on coastal chimneys. For St. George installations, we stock and install professional-grade materials from DuraFlex, HeatShield, and Olympia Chimney - brands engineered for high-moisture, salt-air environments. DuraFlex’s 316Ti stainless handles the acidic flue gases and salt exposure better than standard 304 grades. HeatShield’s cerfractory resurfacing system restores eroded flue surfaces when full liner replacement isn’t necessary. Having these materials on hand means faster turnaround for St. George homeowners, especially when a post-storm inspection reveals damage that can’t wait.
Common Chimney Liner & Rebuild Problems We See in St. George Homes
- Galvanized caps rusted through in 3-5 years. On harbor-facing chimneys near St. George’s waterfront, salt air pits galvanized steel fast. We replace with stainless caps that last decades, not seasons, and we inspect before the metal shows red rust, not after.
- Crown cracks letting nor’easter water into the stack. The north-facing slope takes the full force of harbor wind and rain. Water enters crown cracks, freezes, expands, and opens the flue to progressive masonry damage until the crown is rebuilt with proper slope and overhang.
- Coal-era chimneys with bare thimble connections. Many St. George row houses converted from coal to oil with nothing more than a thimble punched through old brick - no liner, no proper clearance, and a direct carbon monoxide risk under current NYC DOB rules.
- Spalling brick faces from freeze-thaw cycling. Once mortar joints erode from salt and moisture, brick faces pop off the stack. This is cosmetic at first, then structural. We catch it during Level-2 inspection and rebuild before the stack leans.

FAQs - Chimney Liner & Rebuild in St. George
Your chimney sits in direct harbor salt spray on St. George’s north-facing slope, while inland Staten Island chimneys are shielded from the prevailing wind and salt air. Galvanized steel caps begin pitting within 3-5 years here versus 10-15 years inland. We install stainless caps on every St. George rebuild for this exact reason. Call (516) 613-3035 to schedule an inspection - we’ll show you the condition of your cap and crown with photos you can see.
No. A bare thimble punched through old brick with no flue liner violates NYC Department of Buildings clearance and venting requirements, and it creates a carbon monoxide hazard. This conversion is endemic to St. George’s attached row houses, and we open this conversation on virtually every inspection we do in the neighborhood. We replace the thimble with a proper stainless liner sized for your appliance. Call (516) 613-3035 for a free inspection and written verdict.
Annual inspection is the minimum for harbor-exposed chimneys in St. George; we recommend every 6-12 months for north-facing stacks that take the full brunt of salt spray and nor’easter wind. The salt accelerates metal corrosion and mortar erosion at roughly twice the inland rate. Our Level-2 camera inspection documents every finding with photos and a plain-English report. Call (516) 613-3035 to book - estimates are free.
The cap fails first, then the crown, then water enters through flashing gaps to damage the liner or the unlined brick beneath. On a coal-era attached row house near St. George’s waterfront grid, our tech pulled a galvanized cap pitted through by salt air and found the crown cracked with flashing gaps feeding water into the stack through freeze-thaw cycles. After a Level-2 inspection, we rebuilt the crown, re-flashed the chimney, and dropped a DuraFlex stainless liner through the original unlined brick, replacing the bare thimble connection that had been venting the oil burner. The result: restored draft, a compliant flue, and no more spalling brick faces on the harbor side. Call (516) 613-3035 if you suspect similar damage.
Stainless, exclusively. Galvanized components on St. George’s harbor-facing chimneys are false economy - they rust through in a few seasons and open the flue to water damage. We specify stainless caps, stainless flashing where applicable, and stainless liners from DuraFlex or Olympia Chimney for every coastal job. The upfront cost is higher; the 15-20 year service life versus 3-5 years for galvanized makes it the only sensible choice. Call (516) 613-3035 for an estimate.
