We’ve been working the chimneys of Yonkers, NY since 1984. That’s forty-two years of tracing flues through rowhouse walls near Getty Square, sizing liners for converted coal boilers in 10703, and rebuilding spalling brick stacks on the western slopes above the Hudson. The city doesn’t throw us curveballs anymore. We know the building department’s permit requirements for multi-family chimney work. We know which blocks have the 1920s two-families with the original clay flues that never got a liner during the oil conversion. And we know that when a backdraft blows soot into a second-floor apartment on a January night, the superintendent needs someone who picks up the phone.

Why Hearthstone Chimney Co. Is Yonkers’s Preferred Chimney Liner & Rebuild Company

Yonkers is not a suburb with fireplaces. It’s a city with chimneys that heat buildings. Our reputation here was built on understanding that difference.

We arrive when we say we will. Our technicians are background-checked, uniformed, and carry the materials to finish most liner installations and partial rebuilds in a single visit. No return trip to order parts, no leaving you with a cold boiler while we source components. We stock DuraFlex, HeatShield, and Gelco products specifically for the flue sizes and configurations common in Yonkers’s older housing.

Every inspection ends with photographs you can see and a plain-English verdict. No jargon, no scare tactics, no push to oversell. If your clay liner has minor gaps and a HeatShield cerfractory application will do the job, we’ll tell you. If the flue is compromised and needs a full stainless steel liner replacement, we’ll show you the camera footage and explain why.

Our 90-Day Done Right Promise applies to every job in Yonkers. In writing. No arguing. If it’s not right, we come back. That’s the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it. Russell Haines put that in place when he founded this company, and it hasn’t changed.

Our Chimney Liner & Rebuild Services in Yonkers

Stainless Steel Liner Installation

Stainless steel liners are the right choice for most Yonkers oil and gas boiler flues, especially in the pre-1940 multi-family buildings where the original clay tile has cracked from decades of thermal cycling. We install DuraFlex and Olympia Chimney stainless liners sized precisely to your appliance’s BTU output and draft requirements. In the rowhouse blocks near Ludlow Street and Ashburton Avenue, where exterior chimney stacks are narrow and shared, our crew measures carefully to ensure the liner diameter meets NFPA 211 standards without crowding adjacent flues.

Flexible Liner Installation

Flexible liners solve the offset and bend problems common in Yonkers’s older masonry. Many chimneys in 10701 and 10705 were built with slight offsets where the flue passes through floor structures, and rigid liners simply won’t navigate them. Our flexible DuraFlex installations accommodate these irregularities while maintaining proper draft. For buildings on the steep grades near Park Hill or the Hudson waterfront, where chimneys may have settled slightly over a century, flexibility isn’t a convenience - it’s the only way to get a liner seated properly.

Liner Replacement

Replacing a failed liner in Yonkers often means extracting deteriorated clay tile from a flue that was never designed for modern combustion appliances. We’ve replaced liners in buildings where the original 1920s clay was sized for coal and later stressed by oil conversion, and in mid-century ranches in 10704 where clay liners have simply reached end of life. Our process includes a Level-2 camera inspection before and after, documented with photos, so you see exactly what changed and why.

Partial Chimney Rebuild

Partial rebuilds target the most vulnerable sections of Yonkers chimneys: our Chimney Cap & Crown in Yonkers work covers the crown, the top courses of brick, and the interior flue walls. The Hudson River valley wind corridor hits the western-facing slopes hard. Freeze-thaw cycles driven by northwest winds off the river accelerate spalling and mortar deterioration in chimneys above the roofline. We rebuild with proper crown slope, expansion joints, and water shedding designed for this specific exposure. A partial rebuild in Yonkers typically addresses the top 4-6 feet of stack - enough to stop water intrusion without the cost of full demolition.

Full Chimney Rebuild

Full rebuilds are necessary when the structural integrity of a shared stack is compromised, a scenario we encounter in Yonkers’s densest multi-family housing. When multiple flues in a single exterior chimney have suffered liner collapse, mortar loss, or brick displacement, partial repairs become false economy. We dismantle and rebuild with new flue liners for each unit, proper separation between flues, and exterior masonry matched to the original where required by local preservation guidelines. These are complex jobs requiring scaffolding, permits, and coordination with building management - work we’ve done repeatedly in Yonkers’s western ZIP codes.

Liner Repair

Not every damaged liner needs replacement. For clay flues with isolated cracking, joint gaps, or minor spalling, HeatShield cerfractory resurfacing can restore a sound flue surface at roughly half the cost of liner replacement. We assess candidly: if the damage is localized and the structural clay is sound, repair is the square deal. If the flue has shifted, bellied, or suffered through-wall cracking, we’ll tell you replacement is the only safe option. No surprises on the bill, and no repairs we can’t stand behind.

Trusted Brands We Service in Yonkers

We work exclusively with professional-grade materials from manufacturers who understand the demands of Northeast chimney systems. Our trucks carry DuraFlex flexible and rigid stainless liners, HeatShield cerfractory repair products, and Gelco chimney caps and accessories sized for the multi-flue configurations common in Yonkers - part of our Fireplace Services in Yonkers. We also source Olympia Chimney components when specifications require them. These are not builder-grade substitutes. They’re the materials we trust for installations that need to last decades in freeze-thaw cycling, acid condensation from efficient boilers, and the physical stress of shared-stack construction. Because we stock for Yonkers’s specific housing stock, we don’t leave your job to wait on a parts order.

Common Chimney Liner & Rebuild Problems We See in Yonkers Homes

• Shared-stack flue confusion in multi-family buildings. In the dense rowhouse blocks near Getty Square, a single exterior chimney commonly contains three or four independent oil-burner flues serving separate apartments. Our crew positively identifies and traces each flue before any liner work begins. Displacing soot into a neighboring unit is not an option.
• Backdraft and downdraft from Hudson River winds. Homes on the western-facing slopes in 10701 and 10703 sit in a wind corridor that channels northwest gusts up the river valley. Improper cap height, flue diameter, or liner termination can turn a functional chimney into a smoke spill problem. We size and cap for this specific exposure.
• Clay tile deterioration from oil conversion without relining. Thousands of Yonkers boilers were converted from coal to oil in the 1950s-1970s without proper liner upgrades. The resulting acidic condensation attacks clay tile from the inside out, a hidden problem we find regularly in camera inspections of 10703 and 10705 buildings.
• Spalling brick and mortar loss at the crown. The combination of freeze-thaw cycling and wind-driven rain on exposed chimney tops above Yonkers’s flat and low-slope roofs causes accelerated deterioration. We rebuild crowns with proper overhang, drip edges, and slope to shed water - not just patch with more mortar that will fail next spring.
