We’ve been dispatching crews from our New York City office to Yonkers homes for decades. We know the difference between a 1920s Park Hill three-flue stack and a 1950s east-ridge ranch with a single fireplace. That familiarity matters. The chimney problems we find off Broadway in Nodine Hill are not the same problems we find in Bronxville or Scarsdale. In Yonkers, the defining issue is usually liner integrity inside aging masonry that has been through multiple fuel conversions - coal to oil to gas - without ever being properly relined.

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

Our reputation in Yonkers was built on documenting what we find and explaining it in plain English. Every Level-2 inspection ends with photos you can see and a written verdict. No guesswork. No pressure. If we recommend a stainless steel liner or a partial rebuild, we show you exactly why.

Homeowners in Yonkers call us because we’ve been here long enough to understand what these buildings are. A pre-1940 attached brick rowhouse with a shared party-wall stack is a different animal from a suburban colonial. Our technicians trace and label every flue before touching anything. In a building where three or four households share one masonry chase, getting the wrong flue is not a mistake we make.

Calls are answered by a live person, 24 hours a day, 7 days a week. Not a voicemail. Not a callback queue. Our background-checked, uniformed technicians carry the materials to complete most liner and rebuild jobs in a single visit, and our no-hassle upfront pricing means the number on the estimate is the number on the invoice.

Every job is backed by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back and make it right. That’s the Keystone Standard. We’ve been serving local communities for over 42 years, and we plan to be here in thirty more.

Our Chimney Liner & Rebuild Services in Yonkers

Stainless Steel Liner Installation

A stainless steel liner is the right fix for most Yonkers chimneys where the original clay flue tiles are cracked, spalled, or missing altogether. In the pre-1940 rowhouses west of the Saw Mill River Parkway, we regularly find flues that were never lined when the building converted from coal to oil to gas. A DuraFlex stainless liner gives you a sealed, properly sized combustion path that meets modern code and protects the surrounding masonry from heat transfer and creosote penetration. Typical cost in Yonkers: $2,800-$4,500 for a standard fireplace flue, including installation and the final camera verification.

Flexible Liner Systems

Some Yonkers stacks have offsets, bends, or tight clearances that make a rigid stainless liner impossible to feed. For those, we use flexible liner systems that navigate the irregular masonry while still delivering the same sealed combustion path. This is common in the older tenement-style apartment buildings where the flue path was never straight to begin with. Flexible liners are especially useful when we’re working around existing boiler or water-heater connections in a multi-flue stack.

Liner Replacement & Liner Repair

Not every damaged liner needs full replacement. In some Yonkers chimneys, we can repair localized damage using HeatShield cerfractory resurfacing on cracked clay tiles, or spot-repair spalled joints with engineered refractory materials. This works when the overall liner structure is sound and the damage is limited to specific sections. We make this call only after camera inspection and photo documentation. If the clay is too far gone - which it often is in century-old Yonkers flues that have survived multiple fuel conversions - we recommend full replacement and explain exactly why. Liner repair in Yonkers typically runs $1,200-$2,400; full replacement with stainless steel starts around $2,800.

Partial Chimney Rebuild

A partial rebuild addresses the masonry above the roofline: the crown, the cap, the top courses of brick, and sometimes the upper flue lining. In Yonkers, this is often necessary when Hudson-corridor weather has been eating at the stack for decades. The salt-laden, wind-driven rain on river-facing buildings accelerates mortar joint failure and rusts through galvanized caps and flashing that should have been stainless from the start. We rebuild with proper crown slope, drip edges, and stainless or copper caps that can handle what the Hudson throws at them. Partial rebuilds in Yonkers range from $3,500-$7,000 depending on stack height, scaffolding needs, and whether we’re also dropping a new liner.

Trusted Brands We Service in Yonkers

We work exclusively with professional-grade materials from HeatShield, Gelco, and Olympia Chimney - no builder-grade substitutes. HeatShield’s cerfractory resurfacing system lets us restore cracked clay flue liners in Yonkers rowhouses where full replacement would require dismantling a party-wall stack. Gelco caps and accessories hold up to the Hudson-corridor exposure that ruins lesser hardware. Olympia Chimney supplies the stainless steel components we need for proper liner sizing and termination. We stock the common sizes and configurations for Yonkers’s typical flue dimensions, so we’re not waiting on parts while your chimney sits open to the weather.

Common Chimney Liner & Rebuild Problems We See in Yonkers Homes

• Galvanized caps and flashing rust through in as little as 5-7 years on river-facing Yonkers rooftops where the Hudson corridor channels damp, salt-laden air against the stack. Once the cap is perforated, water runs straight down into lime-mortar joints and clay flue liners that are already a century old. We replace with stainless or copper, properly flashed and counterflashed.
• Freeze-thaw cycling cracks original clay flue tiles and erodes mortar in unlined or never-relined coal-to-oil-to-gas conversion flues throughout Westchester. The damage is often hidden until a Level-2 camera inspection reveals it. Third-degree creosote glazing and carbon monoxide can then travel through the masonry itself rather than up the stack.
• Shared party-wall stacks with multiple flues get cleaned or scoped without proper tracing and labeling. In Yonkers’s older rowhouse blocks, a single exterior chimney commonly contains three or four separate flues serving different units or appliances. A brush, liner, or rebuild scope applied to the wrong flue has real carbon-monoxide consequences in a building where multiple households depend on correct identification.
• Abandoned flues from previous fuel conversions become hidden hazards. We regularly find sealed oil flues or blocked coal chutes that still connect to active living spaces, collecting moisture and spalling debris that compromises adjacent active flues. Mapping the full stack before any work begins is non-negotiable on our Chimney Liner & Rebuild jobs.
