Why Hearthstone Chimney Co. Is Yonkers’s Preferred Chimney Cap & Crown Company
Forty-two years in this trade means we’ve worked on Yonkers chimneys through every kind of weather the Hudson Valley throws at them. We’ve replaced caps torn off by nor’easters in the western slopes of 10701, and we’ve rebuilt crowns on mid-century colonials in 10710 where the original concrete simply aged out. Our customers in Yonkers know our name because we document every inspection with photos they can see, and we explain what we’re finding in plain English - no scare tactics, no jargon.
We’re not a chain sending whoever is available that day. Our technicians are background-checked, uniformed, and trained specifically on the multi-flue shared chimneys that dominate Yonkers’s older housing stock. The 90-Day Done Right Promise governs every job: if it’s not right, we come back and make it right, in writing, no arguing. That promise has kept us in business across Westchester and the Bronx since 1984, and it’s why Yonkers homeowners call us back when they need Chimney Liner & Rebuild in Yonkers or their annual Chimney Cleaning & Sweep in Yonkers.
Response time matters when water is entering your flue. From our dispatch, we typically reach Yonkers properties within 60 to 90 minutes during standard hours, and we maintain true emergency availability for cap blow-offs and crown failures that expose the chimney interior. A live person answers the phone 24 hours a day, 7 days a week - not a voicemail, not a callback queue.
Our Chimney Cap & Crown Services in Yonkers
Chimney Cap Installation
New cap installation in Yonkers demands attention to flue count and wind exposure. In the dense rowhouse blocks near Getty Square and along Ashburton Avenue, a single exterior stack often carries three or four independent flues for separate apartments. We measure each flue precisely, specify multi-flue caps with proper clearance, and secure them against the channeled northwest winds that come off the Hudson. A standard single-flue cap installation in Yonkers runs $280-$420, including a stainless-steel unit from Famco or Copperfield and proper fastening to the flue tile or chimney shoulder.
Chimney Cap Replacement
Caps don’t last forever in this climate. The combination of road salt aerosol from the Saw Mill River Parkway corridor, freeze-thaw cycling, and wind-driven rain corrodes galvanized units in five to seven years. We remove the failed cap, inspect the flue top for hidden deterioration, and install a replacement sized to the actual flue opening - not the nearest stock size. Replacement jobs in Yonkers typically cost $240-$380 for standard flues, with multi-flue configurations ranging $340-$580 depending on stack width and access.
Crown Repair
The concrete crown is your chimney’s umbrella. In Yonkers’s pre-1940 housing stock, original crowns were often poured too thin, without proper overhang or drip edge, and forty years of thermal cycling has taken its toll. We cut out deteriorated concrete, rebuild to proper thickness with engineered crown mix, and form a minimum two-inch overhang to shed water away from the masonry face. Crown repair in Yonkers generally runs $480-$720 for partial rebuilds, $890-$1,400 for full crown replacement on larger multi-flue stacks.
Crown Coating
When the crown is structurally sound but weathered and hairline-cracked, a professional-grade coating extends its life five to ten years without the cost of full rebuild. We use flexible, breathable formulations - HeatShield and compatible systems - that move with the concrete rather than trapping moisture underneath. Crown coating in Yonkers costs $320-$480, and we only recommend it when our Level-2 camera inspection and physical assessment confirm the underlying concrete is viable. No coating saves a crown that’s already spalling or separating from the flue.

Trusted Brands We Service in Yonkers
We don’t use builder-grade substitutes. For cap and crown work in Yonkers, we specify stainless steel and copper caps from Famco and Copperfield, and we carry DuraFlex liner components when crown removal reveals flue damage that needs simultaneous repair. Our trucks stock the common sizes for Yonkers’s typical flue dimensions - the 8×8, 8×12, and 13×13 tiles found in local rowhouse and colonial construction - so we’re not ordering parts and making you wait. When a custom-fabricated cap is needed for an unusual multi-flue configuration, we measure, spec, and install without the markup you’d see from a middleman.
Common Chimney Cap & Crown Problems We See in Yonkers Homes
- Wind-driven blow-offs on western-facing slopes. Homes in the 10701 and 10703 ZIPs, rising steeply from the Hudson, catch channeled northwest winds that test any cap installation. We regularly find caps that were properly installed inland but failed here because the flue overhang and fastening pattern weren’t specified for this exposure.
- Crown deterioration from freeze-thaw on unlined or partially lined flues. In Yonkers’s converted coal-era chimneys, exhaust temperatures are often lower and wetter than the original design anticipated. That moisture migrates into the crown concrete, freezes, and accelerates spalling - a pattern we see constantly in the two-family and walk-up stock near Ludlow Park and along Riverdale Avenue.
- Multi-flue caps installed without proper partition or clearance. A single cap covering multiple flues must maintain separation to prevent cross-drafting and soot migration between units. In Yonkers’s shared chimneys, we’ve corrected numerous installations where a previous contractor simply set a wide cap over the whole stack, creating downdraft problems for the upper floors.
- Rust jacking on galvanized caps in salt-air exposure. The Hudson corridor carries enough marine aerosol to corrode standard galvanized steel within a few years. We replace these with 304 or 316 stainless steel as standard practice, and we see the difference in longevity - fifteen to twenty years versus five to seven.

Three factors move these numbers: access complexity (steep roofs, narrow alley-side stacks), flue count and configuration, and whether removal of the old cap or crown reveals hidden damage to the flue top or shoulder that needs repair before the new work can go on. We assess all of this during our free estimate visit, and we give you the full number before we start - the number on the estimate is the number on the invoice. Seniors and veterans receive a permanent 5% discount, and we offer $50 off any repair over $250. Call (844) 803-1545 to schedule your free estimate.

FAQs - Chimney Cap & Crown in Yonkers
We typically arrive within 60 to 90 minutes for standard appointments, and we maintain true emergency availability for cap blow-offs and crown failures that leave your flue open to weather. Call (844) 803-1545 any hour - a live person will answer and dispatch the nearest available technician.
We cover all Yonkers ZIPs including 10701, 10702, 10705, and 10710, from the rowhouse blocks near Getty Square and Ludlow Park in the west to the mid-century ranches and colonials along Midland Avenue and in the 10710 area. Our technicians know the distinct chimney types in each zone and carry the appropriate cap sizes and crown materials for both the multi-flue shared stacks and single-family fireplace flues common in those neighborhoods.
Yes. A missing or damaged cap and a cracked crown both qualify as emergency conditions because they allow direct water entry into the flue and firebox. We answer emergency calls 24 hours a day, 7 days a week, with a live person on the phone - not a voicemail system. Most emergency caps can be temporarily secured or permanently replaced in the same visit.
Not at our company. Our pricing is consistent across Yonkers, Bronxville, Mount Vernon, and the other communities we serve. The only variables are the physical job conditions - flue count, access difficulty, and whether hidden damage extends the scope - not the ZIP code. We also offer a free second opinion on any written estimate you’ve received, so you can compare apples to apples.
Every cap and crown job is covered by our 90-Day Done Right Promise: if it’s not right, we come back and make it right, in writing, no arguing. Beyond that, the stainless-steel caps we install from Famco and Copperfield carry manufacturer warranties of fifteen to twenty years against corrosion and defects. Crown repairs and coatings are warranted for two years against material failure when applied to structurally sound substrates we’ve verified. Call (844) 803-1545 for a free estimate - we’ll assess your specific chimney and explain exactly what coverage applies.
