Why Hearthstone Chimney Co. of New York City Is New Square’s Preferred Chimney Liner & Rebuild Company
We’ve worked in New Square long enough to understand what other companies miss. The village isn’t a standard Rockland County suburb. It’s a self-contained Skverer Hasidic community where every service call moves through word-of-mouth referrals, and where showing up on Erev Yom Tov or calling during Shabbat doesn’t just cause a cancellation - it ends the relationship. Our technicians learn the calendar. We schedule around Friday sundown through Saturday night, around Rosh Hashanah, around Pesach. That respect has earned us repeat calls from homes off Cherry Lane and throughout the 10956 zip code.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. The 90-Day Done Right Promise covers every liner and rebuild job in writing: if it’s not right, we come back, no arguing, no paperwork to dig up. Over 42 years in business, founded in 1984, we’ve learned that a square deal builds more trust than any slogan.
Most jobs complete in a single visit. Our technicians are background-checked, uniformed, and trained specifically on the failure modes we see in New Square’s 1960s-1990s housing stock. No-hassle upfront pricing means the number on the estimate is the number on the invoice.
Our Chimney Liner & Rebuild Services in New Square
Stainless Steel Liner Installation
New Square’s original clay flue liners, installed in homes built from the 1960s through the 1980s, were never designed for the heating loads these houses now carry. Large Hasidic households run boilers and stoves longer and harder than the engineers anticipated. We install DuraFlex stainless steel liners that handle higher temperatures and resist the acidic condensation that forms when exhaust cools too quickly in a damaged flue. A typical stainless steel liner installation in New Square runs $2,800-$4,500, including the tear-out of the old clay and proper connection to your appliance. Most jobs finish in one day.

Flexible Liner Solutions
Some of New Square’s older chimneys have offset flues or tight cleanout passages that rigid pipe won’t navigate. For these homes, typically the narrower brick structures near the village center, we use flexible stainless liners that conform to existing channels without breaking masonry. Flexible liner installation in New Square generally costs $3,200-$5,000, depending on length and access. We size every liner to the appliance, not the other way around. Oversized liners cause poor draft and creosote buildup; undersized ones overheat. Our measurements are precise.

Liner Replacement for Failed Clay Flues
On a 1970s brick-and-frame home on Park Lane, we found the original clay flue liner shattered by freeze-thaw cycling, with gaps letting heat into the wood framing. Our crew installed a DuraFlex stainless steel liner and rebuilt the top three courses of masonry, restoring safe venting ahead of the long Rockland County heating season. This is a common scenario in New Square. The Hudson Valley’s humidity and freeze-thaw cycling - temperatures swinging from single digits to above freezing in a week - spalls clay and erodes mortar joints faster than inland climates. Full liner replacement with spot masonry repair in New Square typically ranges from $3,500-$6,000.

Partial Chimney Rebuild
When mortar joint erosion advances beyond what repointing can fix, or when the top courses of brick have loosened from years of overfiring, a partial rebuild becomes necessary. In New Square, we see this more often than in comparable-age housing elsewhere because the heating load is simply higher. A partial rebuild addresses the stack above the roofline, or sometimes a specific face of the chimney, while preserving the sound lower structure. Costs in New Square run $4,500-$7,500 depending on height, scaffolding needs, and whether the crown also requires replacement. Most partial rebuilds take two days.

Full Chimney Rebuild
For chimneys where the structural integrity has failed throughout - leaning stacks, extensive spalling, or internal collapse - we offer full rebuilds using matching brick and proper flashing integration with your roof. Full rebuilds in New Square start around $8,500 and can exceed $15,000 for taller structures with complex crown and cap requirements. We handle permits, coordinate scheduling around your availability and the calendar, and leave the site clean.

Trusted Brands We Service in New Square
We don’t use builder-grade substitutes. For New Square homes, we stock and install professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney. DuraFlex stainless liners handle the aggressive cycling these heating systems demand. HeatShield cerfractory flue resurfacing can restore sound clay flues with minor surface damage without full relining, saving some homeowners significant cost. Gelco and Olympia Chimney caps and crowns resist the Hudson Valley’s humidity and UV exposure better than hardware-store versions. We keep common sizes in our regional warehouse, so most New Square repairs don’t wait on shipping.
Common Chimney Liner & Rebuild Problems We See in New Square Homes
- Freeze-thaw shattered clay flues. Rockland County winters deliver sustained cold from November through March, with repeated freeze-thaw cycles that crack original clay liners installed in 1960s-1980s homes. Once cracked, the liner can’t contain heat or gases safely.
- Accelerated mortar erosion from overfiring. New Square’s large households push heating appliances beyond their design capacity. Mortar joints that should last 60 years deteriorate in 30, making partial rebuilds necessary sooner than expected.
- Creosote-glazed flues from extended burn seasons. Longer heating cycles mean more creosote accumulation. In a damaged liner, that creosote can ignite or block venting entirely.
- Improperly scheduled service causing dangerous delays. When technicians ignore Shabbat and holiday windows, homeowners postpone critical repairs. We’ve seen cracked liners left unaddressed through entire heating seasons because previous companies couldn’t accommodate the calendar.

Yes, in most cases we install a stainless steel liner inside the existing flue without dismantling the chimney structure. We remove the damaged clay through the top and bottom openings, then run a properly sized DuraFlex liner with insulation where code requires. On a recent job off Robert Pitt Drive, we relined a 1972 chimney in one day, saving the homeowner a rebuild that another company had proposed.
Thirty years is early for a well-maintained chimney, but New Square’s heating loads are not typical. Large households running systems harder than designed accelerate mortar joint erosion and spalling. Freeze-thaw cycling in the Hudson Valley finishes what overfiring starts. A partial rebuild addresses the damaged section while preserving sound masonry below. It’s repair, not replacement, done right - and we stand behind it.
A properly sized stainless steel liner improves draft by creating the correct ratio of flue area to appliance output, and it resists the acidic moisture that humid climates produce. In New Square, where summer humidity seeps into chimney systems and winter condensation forms quickly, stainless steel outperforms clay and terracotta. Better draft means more complete combustion, less creosote, and safer operation. Call (855) 950-3861 for an exact assessment of your stove and chimney.
Yes, we stock Gelco caps, Olympia Chimney crown forms, and related hardware for the dimensions common in 1960s-1990s construction. Most New Square repairs don’t wait on shipping. If your chimney needs a cap, crown, or top-sealing damper, we measure on site and install from inventory or our regional warehouse within days. For an exact quote on your repair, call (855) 950-3861 - estimates are free.
