Call (855) 950-3861

We’ve been working on Yonkers chimneys since 1984. We know the Southwest Yonkers blocks off Palisade Avenue, the three-family stacks in Getty Square, and the steep-roofed homes climbing toward Crestwood. These aren’t suburban fireplaces with easy ladder access and single flues. They’re century-old masonry chimneys, often shared between households, with crowns that have taken forty freeze-thaw cycles and caps that were last replaced during the Reagan administration. When you call us at (855) 950-3861, a live person answers, 24 hours a day. We schedule you fast, show up when we say, and give you upfront pricing before we start.

Why Hearthstone Chimney Co. of New York City Is Yonkers’s Preferred Chimney Cap & Crown Company

Forty-two years in this trade means we’ve seen what Yonkers chimneys do. The oversized flues built for coal furnaces, later converted to oil, now venting gas - they condense moisture that rots standard caps from the inside out. The Hudson River downdrafts that hit east-facing roofs and reverse draft under poorly designed caps. The party-wall stacks where one owner’s missing cap becomes the neighbor’s carbon monoxide risk. We document every inspection with photos you can see and a plain-English verdict. No jargon, no scare tactics, just what we found and what it means.

Yonkers homeowners call us back because we treat their house like we plan to be in business another thirty years. We do. Our 90-Day Done Right Promise is in writing, no arguing. If it’s not right, we come back. Background-checked, uniformed technicians. Most jobs done in one visit. No surprises on the bill - the estimate number matches the invoice number.

We replaced a copper multi-flue cap on a shared chimney stack in the Southwest Yonkers blocks off Palisade Avenue. The old cap was missing a leg, letting rain directly into one flue while the adjacent flue’s liner was exposed - a CO hazard we flagged. We installed a custom Famco copper cap with stainless mesh and sealed both crown tops with HeatShield coating. That’s the kind of job we do in Yonkers.

Our Chimney Cap & Crown Services in Yonkers

Cap Installation

New cap installation in Yonkers runs $280-$520 for a standard single-flue stainless cap with mesh screening. On the prewar brick row houses in 10701 and 10705, we often find flue openings that don’t match modern standard sizes - the legacy of coal-to-gas conversions that left oversize terra cotta liners or unlined brick flues. We measure on site and source the correct fit from Copperfield or Gelco inventory we carry, so we’re not making you wait for a second trip.

Cap Replacement

Cap replacement in Yonkers is our most common call. The freeze-thaw cycles in the lower Hudson Valley crack galvanized caps in five to seven years. We remove the failed unit, inspect the crown beneath it for spalling or water intrusion, and install a replacement that actually fits your flue and your roof pitch. A proper replacement costs $320-$580 in Yonkers, including inspection of the crown condition underneath.

Crown Repair

Crown repair addresses the concrete slab that seals the top of your chimney stack. In Yonkers’s century-old masonry, we’ve found crowns poured with old sand-mix concrete that lacks the control joints and overhangs specified by modern code. Water gets in, freezes, pops off surface chunks. We cut back to sound material, form a proper slope and drip edge, and pour new crown mix rated for freeze-thaw exposure. Typical crown repair in Yonkers: $480-$760.

Crown Coating

Crown coating with HeatShield is our preferred preventive treatment for Yonkers chimneys where the crown is sound but weathered. We apply a flexible, waterproof membrane that bridges hairline cracks and sheds water without trapping vapor inside the masonry. At $340-$490, it’s roughly half the cost of full crown rebuild and adds ten to fifteen years of service life on a Yonkers chimney that faces full four-season exposure.

Multi-Flue Cap

Multi-flue caps are essential in Yonkers. The three-family buildings and attached row houses throughout 10701, 10705, and 10710 frequently vent two or more appliances through separate flues in a single masonry stack. A multi-flue cap covers the entire crown, protecting all flue openings and reinforcing the structural integrity of the top course. We fabricate and install multi-flue caps from Gelco and Famco starting at $620 for stainless, $890 and up for copper on historic properties.

Custom Cap

Custom caps solve the fit problems that standard sizes can’t touch. Yonkers’s coal-era chimneys often have odd flue spacing, extended shoulders, or decorative brickwork that a catalog cap won’t accommodate. We measure, sketch, and order custom fabrications from Copperfield and Olympia Chimney with typical turnaround of five to seven business days. Custom cap work in Yonkers ranges $740-$1,280 depending on metal choice and complexity.

Trusted Brands We Service in Yonkers

We don’t use builder-grade substitutes. Our Yonkers trucks stock professional-grade materials from DuraFlex, HeatShield, Gelco, and Famco - the brands that other chimney companies order when they get a job they can’t handle with hardware-store inventory. For crown coatings, we apply HeatShield’s elastomeric system because it moves with the masonry through freeze-thaw cycles rather than cracking off like rigid sealers. For custom caps on the historic homes near Untermyer Park and along Warburton Avenue, we specify Copperfield and Olympia Chimney copper work that weathers to the brown patina Yonkers homeowners expect on a century house. Parts on the truck mean we finish most Yonkers jobs in a single visit, not two.

Common Chimney Cap & Crown Problems We See in Yonkers Homes

• Condensation corrosion from oversized flues. Yonkers’s dominant housing stock - dense attached row houses and two- and three-family buildings erected between roughly 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 that corrodes standard caps and deteriorates crowns from within.
• Hudson River downdrafts reversing draft. Yonkers sits in the lower Hudson River Valley, where the river corridor channels prevailing winds and creates rooftop downdraft conditions - particularly on the steeper east-facing slopes that rise sharply from the waterfront - that can reverse draft in improperly capped or undersized chimney terminations, forcing exhaust back into living spaces.
• Party-wall shared stacks with neglected adjacent flues. In the tightly packed Southwest Yonkers blocks, attached row houses share party walls that often run directly through a common chimney stack containing flues serving two different households side by side. A technician servicing one unit’s cap who ignores a cracked liner or missing cap on the adjacent flue in the same stack is leaving a carbon-monoxide pathway into a neighbor’s apartment.
• Freeze-thaw spalling on century-old crowns. The full northeastern four-season cycle, including repeated freeze-thaw events each winter, accelerates spalling and mortar-joint erosion in Yonkers’s century-old brick chimneys. We find crown damage at cleaning appointments more often here than in postwar Westchester suburbs because the masonry age and exposure are simply more severe.
