We’ve been working on Yonkers chimneys since 1984. The city’s housing stock is unlike anywhere else in Westchester. Dense rows of attached brick homes built between 1890 and 1940 dominate neighborhoods like Southwest Yonkers and the streets climbing toward Park Hill. These buildings share chimney stacks, party walls, and a history of fuel conversions that created problems suburban chimney companies rarely encounter. We know the difference between a Ludlow flue and a coal-era oversize. We know which blocks have shared stacks that need mapping before any liner goes in. That local knowledge keeps our customers safe and our work lasting.

Our Chimney Liner & Rebuild Services in Yonkers
Stainless Steel Liner Installation
Stainless steel liners are the right choice for most Yonkers row houses, and there’s a specific reason why. In Southwest Yonkers (ZIP 10701, 10705), masonry chimneys built to vent coal furnaces now serve gas appliances, creating oversized flues that cause chronic condensation and acidic liner corrosion - a problem rare in newer suburban Westchester towns. A properly sized stainless steel liner from DuraFlex or Olympia Chimney reduces the flue diameter to match today’s gas equipment, eliminating the condensation that destroys clay tiles and standard aluminum liners within five years. We install these with proper insulation and secure top connections that withstand the wind shear coming off the Hudson.
Flexible Liner Systems
Some Yonkers chimneys have offset flues, corbelled smoke chambers, or structural shifts from a century of freeze-thaw cycles. A flexible liner navigates these irregularities without dismantling the surrounding masonry. We use DuraFlex and HeatShield products rated for the temperature demands of modern gas and oil appliances. In the tighter chimney throats common in three-family buildings along Nepperhan Avenue and South Broadway, flexibility matters. Rigid liners won’t fit. We measure with a video scan before recommending any system.
Liner Replacement
When an existing liner has failed - cracked clay tiles, corroded metal, or gaps at the joints - replacement is not optional. Carbon monoxide and combustion gases leak into wall cavities and living spaces. In Yonkers’s attached housing, that risk extends to neighbors. We remove the damaged liner, clean the flue walls, and install a new system with proper sizing for the appliance being vented. Every replacement includes a post-installation camera inspection and a written certificate of completion.
Partial and Full Chimney Rebuild
The freeze-thaw cycles on Yonkers’s Hudson River waterfront accelerate mortar joint erosion in century-old brick chimneys. Spalling brick, deteriorated crowns, and leaning stacks are not cosmetic issues. They’re structural failures that can collapse onto roofs, sidewalks, or neighboring properties.
A partial rebuild addresses the upper section - typically from the roofline to the cap - where exposure is greatest. Full rebuilds are necessary when the stack has shifted, the wythes have separated, or multiple flues have compromised the structural integrity of the chimney core. We rebuilt a shared chimney stack in a 1905 attached row house on Palisade Avenue (10701), installing a DuraFlex stainless steel liner after the original clay flue tiles had deteriorated from decades of coal-to-gas condensation. The job required mapping three flue channels serving two units and labeling each at the roofline to prevent cross-flue carbon monoxide hazards. That kind of complexity is standard for our Chimney Liner & Rebuild in Yonkers work.

Trusted Brands We Service in Yonkers
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from DuraFlex, HeatShield, Famco, and Copperfield - brands that hold up in the demanding conditions Yonkers chimneys present. Because we stock these parts locally, most Yonkers customers don’t wait for special orders. A liner failure in January doesn’t get a two-week delay while parts ship from a warehouse. We measure, we cut to length on site, and we install. The number on the estimate is the number on the invoice. A square deal: no surprises on the bill.
Common Chimney Liner & Rebuild Problems We See in Yonkers Homes
- Oversized coal-era flues cause acidic condensation. Chimneys built for coal furnaces have flue dimensions far too large for modern gas appliances. The slow-moving flue gases cool, condense, and form sulfuric acid that eats through standard liners within five years. We see this constantly in the 10701 and 10705 ZIP codes.
- Shared party-wall chimneys hide dangerous cracks. In tightly packed Southwest Yonkers blocks, attached row houses share chimney stacks with flues serving two different households. A cracked liner or missing cap in one unit creates a carbon monoxide pathway into the neighbor’s apartment. Suburban Westchester chimney work rarely presents this scale of shared liability.
- Freeze-thaw cycles destroy mortar joints. Yonkers’s position in the lower Hudson River Valley channels prevailing winds and creates rooftop downdraft conditions. Repeated freeze-thaw events each winter accelerate spalling and mortar-joint erosion in century-old brick chimneys. Inspection findings at routine cleaning appointments are unusually frequent here.
- Improper fuel conversions leave dangerous gaps. Many Yonkers buildings converted from coal to oil to gas without proper chimney modifications. Each transition left mismatched flue sizes, missing cleanout doors, and deteriorated thimbles that current homeowners may not know exist until a Level-2 inspection reveals them.
Pricing for Chimney Liner & Rebuild in Yonkers, NY
Here is what chimney liner and rebuild work costs in the Yonkers market. These ranges reflect the complexity of multi-flue, multi-unit buildings common in the city. Single-family homes in the northwest hills may fall at the lower end; shared stacks in Southwest Yonkers row houses typically run higher due to access and mapping requirements.
| Service | Typical Range in Yonkers |
|---|---|
| Stainless steel liner installation (single flue) | $2,800 - $4,500 |
| Flexible liner with offset navigation | $3,200 - $5,000 |
| Liner replacement (remove and reinstall) | $2,200 - $4,000 |
| Partial rebuild (upper section, roofline to cap) | $3,500 - $7,500 |
| Full chimney rebuild (multi-flue stack) | $6,500 - $12,000 |
| Liner repair (patch, seal, or localized fix) | $800 - $2,200 |
What moves a job toward the higher end: multiple flues requiring individual liners, shared stacks needing neighbor coordination, scaffolding for tall or tight-access buildings, and masonry matching for historic brick. We provide no-hassle upfront pricing after a Level-2 inspection. The estimate is free. Call (855) 950-3861 to schedule.

FAQs - Chimney Liner & Rebuild in Yonkers
Yonkers’s dominant housing stock - dense attached row houses built between 1890 and 1940 - contains oversized masonry chimneys originally built for coal furnaces, later converted to oil burners, and now frequently venting gas appliances. That triple-fuel history leaves flues dimensioned for coal that are far too large for today’s gas equipment, producing chronic flue-gas condensation and acidic liner deterioration that suburban homes with properly sized modern chimneys rarely experience. A stainless steel liner correctly sizes the flue for the appliance, eliminating the condensation problem. Call (855) 950-3861 for a free inspection and estimate.
We can inspect the flue serving your unit from your side, but a complete assessment of a shared stack requires visual access to all flue terminations and often the adjacent cleanout or basement connector. We coordinate with neighbors when possible and document what we can see from the roofline and your unit. If a neighbor’s flue shows visible damage from the exterior, we note it in our report. Safety in shared stacks is a shared responsibility. Call (855) 950-3861 and we’ll explain what your specific building requires.
Annual Level-2 inspection is the standard for Yonkers’s older housing stock, given the accelerated deterioration from freeze-thaw cycles, coal-era flue sizing, and multi-appliance use. Buildings with active heating appliances running through winter should not go more than 12 months without a camera inspection. We often find significant liner degradation in chimneys that appeared fine from the outside. The $89 Seasonal Tune-Up includes a basic visual and flue check; a full Level-2 with video is additional and recommended for buildings over 75 years old.
Tar-like or white powdery residue on the flue walls, pieces of clay tile in the cleanout, rust stains on the boiler or water heater jacket, and persistent moisture or efflorescence on interior chimney breast walls all indicate liner failure. In gas-heated homes, sooty or rust-colored condensation at the flue connection is a warning that the flue is oversized and cooling too quickly. Carbon monoxide detector alarms should never be ignored. If you see any of these signs, call (855) 950-3861 for a Level-2 inspection.
Yes, when the damage is confined to the upper third of the stack and the structural core below remains sound. We rebuild from the roofline up, replacing spalled brick, repointing mortar joints, installing a proper concrete crown with positive drainage, and capping with a stainless steel cover. A partial rebuild does not address liner problems inside the flue, so we typically pair it with liner inspection and replacement as needed. We’ll tell you honestly whether partial or full rebuild is the right path after we inspect. Estimates are free - call (855) 950-3861.
