Why Hearthstone Chimney Co. of New York City Is Monsey’s Preferred Chimney Liner & Rebuild Company
We’ve been serving Rockland County communities for over 42 years, and Monsey has been a cornerstone of our route since the early 1990s. Our technicians know the local housing stock - the 1950s Cape Cods on Airmont Road, the 1960s ranches that have sprouted dormers and second-story additions, the converted attics with wood stoves exhausting into chimneys never designed for them.
Our reputation here is built on showing up when we say and leaving the job finished. The 90-Day Done Right Promise covers every liner and rebuild in Monsey - in writing, no arguing. If something isn’t right, we come back. Background-checked, uniformed technicians carry DuraFlex and HeatShield materials on the truck, which means most Monsey homes get same-day completion. No waiting on parts. No second appointment during the busy pre-holiday rush.
We answer the phone with a live person every hour of every day. Not a callback queue. Not an app. A real person who knows Monsey and can dispatch a crew.
Our Chimney Liner & Rebuild Services in Monsey
Stainless Steel Liner Installation
Monsey’s large Orthodox households run wood-burning stoves and fireplaces nearly continuously through cold months, yet every service call must be scheduled around Shabbat (Friday sundown to Saturday night) and an exceptionally dense Jewish holiday calendar - a scheduling constraint unique in Rockland County. We plan our stainless steel liner installations accordingly, arriving with full crews on weekdays and Sunday to complete the job before sundown Friday. A DuraFlex stainless liner is the correct fix for most Monsey chimneys where the original clay flue has cracked from thermal cycling or water intrusion. We size, cut, and insulate on-site, pulling the liner through the existing stack without dismantling the surround.

Flexible Liner Systems
On a post-renovation inspection at a remodeled split-level on Elm Street, we found a cracked clay flue liner beneath a new second-story dormer; the chimney crown had never been resealed. We installed a DuraFlex stainless steel liner and rebuilt the crown in one extended trip, avoiding a second callout during the busy pre-Passover season. Flexible liners solve the offset problems common in Monsey’s modified homes, where additions have shifted chimney alignments. Our Chimney Liner & Rebuild team carries multiple diameters and can adapt to offsets that rigid pipe cannot navigate.

Liner Replacement
The original clay liners in Monsey’s 1960s and 1970s housing stock were built for open fireplaces, not for the wood stoves and inserts that now vent through them. When a liner fails - cracked, glazed with creosote, or corroded from condensing flue gases - replacement is not optional. It’s a safety issue. We remove the damaged liner, inspect the surrounding masonry with our Level-2 camera, and install a new stainless or HeatShield cerfractory flue that matches the appliance’s BTU output and venting requirements. No builder-grade substitutes. Only professional-grade materials, documented with photos you can see and a plain-English verdict.

Partial and Full Chimney Rebuild
Monsey sits at the eastern foot of the Ramapo Mountains, and the wind funneling off those slopes can punish chimneys that lack adequate height above raised ridge lines - a common result of the area’s frequent home additions. When the upper courses of brick have spalled, the crown has disintegrated, or the flue is beyond liner repair, we rebuild. Partial rebuilds address the top third of the stack, common after water damage from un-resealed flashing. Full chimney rebuilds start at the roofline and restore structural integrity with matching brick and proper crown construction. Our crew completes most rebuilds in a single visit, with no-hassle upfront pricing - the number on the estimate is the number on the invoice.

Common Chimney Liner & Rebuild Problems We See in Monsey Homes
- Chimney crowns and step flashing left un-resealed after dormer additions or re-roofing. Monsey’s cycle of home expansion means original chimneys are repeatedly disturbed. Water follows the path of least resistance, saturating the flue and corroding the liner from the outside. We inspect for this on every call.
- Secondary wood stoves or inserts attached to original chimneys without proper stainless steel liner replacement. The original clay flue in a 1965 Monsey ranch was sized for a fireplace, not a 50,000 BTU stove. Undersized or unlined flues leak flue gases and accelerate creosote buildup. This is dangerous. We replace the liner to match the appliance.
- Downdraft problems from inadequate chimney height above raised ridge lines. The Ramapo wind pattern pushes smoke back down stacks that don’t clear the roof plane by at least two feet. A partial rebuild with an extended liner corrects drafting without rebuilding the entire structure.
- Cracked clay flue liners beneath new second-story additions. The thermal expansion of a modified chimney chase, combined with Monsey’s freeze-thaw cycles, fractures old clay. Our camera inspection finds it. Our liner installation fixes it.

FAQs - Chimney Liner & Rebuild in Monsey
Yes, we schedule chimney liner installations during Sukkot and other Jewish holidays, working around the specific observance times for your household. We understand Monsey’s calendar intimately - our technicians know that Sukkot, Pesach, and the High Holidays create compressed windows for home maintenance, and we plan our crew availability accordingly. Call (855) 950-3861 and we’ll find a time that respects your observance. Estimates are free.
Yes, the original clay liner almost certainly needs replacement - it was engineered for an open fireplace, not the concentrated heat and specific venting requirements of a modern wood stove. In Monsey’s 1960s ranches, we’ve found original clay liners cracked, glazed, or undersized for the BTU load of added appliances. This creates flue gas leaks and creosote hazards. We inspect with our Level-2 camera and install a properly sized stainless liner. Call (855) 950-3861 for a free inspection.
A full chimney rebuild in Monsey typically costs $4,500-$6,500, with most projects falling in the $5,200-$5,800 range for a standard two-story home. The price includes demolition of the damaged upper stack, brick matching, crown reconstruction, and installation of a new stainless steel liner. Taller chimneys on homes with raised ridge lines from additions may run higher. We provide upfront pricing after inspection - no surprises on the bill. Call (855) 950-3861 for your exact quote.
Yes, we thoroughly clean the flue and smoke chamber during every rebuild project, removing creosote, debris, and deteriorated liner fragments before installing the new system. In Monsey’s heavy-usage homes, this step is essential - accumulated creosote in a modified chimney is a genuine fire hazard, and we will not install a new liner over a dirty flue. The cleaning is included in our rebuild scope. Call (855) 950-3861 to schedule.
A new liner alone cannot fix a downdraft caused by inadequate chimney height - the stack must extend at least two feet above the highest point within ten feet, and in Monsey’s re-roofed homes with raised ridge lines, it often doesn’t. We correct this with a partial rebuild that extends the chimney to proper height, combined with an insulated liner that maintains flue gas temperature for better draft. The Ramapo wind pattern makes this especially important here. Call (855) 950-3861 for an inspection and upfront estimate.
