We’ve been driving to Hartsdale since 1984 - long enough to know the difference between a Secor Road Tudor and a Ridge Road Colonial just by the chimney profile. Our crews dispatch from the New York City office and carry Copperfield and Famco caps sized for the two-flue masonry stacks that dominate this village’s 1920s-1940s housing stock. When your crown is spalling or your cap has gone missing, you want someone who understands that Hartsdale chimneys weren’t built for today’s appliances and weren’t always built for two flues to stay active.

Why Hearthstone Chimney Co. Is Hartsdale’s Preferred Chimney Cap & Crown Company

Hartsdale homeowners call us because we’ve seen what happens when a neighbor’s orphaned flue vents into a shared stack. Our Chimney Cap & Crown team documents every inspection with photos you can see and a plain-English verdict - no jargon, no pressure, just what is actually wrong and what it costs to fix it right.

We’ve earned a strong local reputation across Westchester County over 42 years, with Hartsdale customers specifically mentioning our thoroughness on shared-stack jobs. Our technicians are background-checked, uniformed, and complete most cap and crown repairs in a single visit. Calls are answered by a live person 24 hours a day, 7 days a week - not a voicemail queue.

We know the local terrain. Hartsdale’s tight lots and attached housing mean roof access can be tricky on streets like East Hartsdale Avenue or the narrower lanes off Secor. Our crews arrive with ladders and rigging suited to these conditions, and we coordinate with neighbors when a shared stack requires access to both properties. The number on your estimate is the number on your invoice. Done right - and we stand behind it with the 90-Day Done Right Promise in writing, no arguing.

Our Chimney Cap & Crown Services in Hartsdale

Cap Installation

New cap installation in Hartsdale runs $180-$340 for a standard single-flue galvanized or stainless unit, or $420-$680 for a custom multi-flue cap that covers both openings of a two-flue stack. Most Hartsdale homes we visit have never had a proper cap on the second furnace flue - or the original 1920s-1940s cap has rusted through or blown off in a Hudson Valley nor’easter. We measure on site, fabricate or stock from Famco and Olympia Chimney inventory, and install same-day in most cases. Every cap is sized to allow proper draft while keeping rain, squirrels, and downdrafts out of flues that were never designed for modern gas appliance exhaust.

Cap Replacement

Cap replacement in Hartsdale costs $220-$480 depending on flue count, cap material, and whether the flue tiles need repair before the new cap seats properly. We see a lot of builder-grade caps that lasted maybe five years before the mesh clogged or the lid warped. We replace with professional-grade stainless or copper from Copperfield and Gelco - materials rated for Westchester’s freeze-thaw cycling and heavy wet snow loads. If your cap came off in last winter’s storm and you can see straight down the flue, call (914) 603-1360. An open flue is an open path for water, animals, and your neighbor’s exhaust if you share a stack.

Crown Repair

Crown repair in Hartsdale typically runs $340-$620 for partial rebuilds of spalled or cracked concrete crowns, or $680-$890 for full crown reconstruction on larger two-flue stacks. Hartsdale’s original crowns were often poured too flat or with too little overhang, so meltwater ponds instead of shedding. Add eighty years of freeze-thaw cycling and Hudson Valley snow loads, and you get the spalling and vertical cracking we find on Ridge Road and East Hartsdale Avenue every spring. We form and pour new crowns with proper slope and drip edges, or apply CrownCoat or HeatShield resurfacing where the substrate is sound but the surface is compromised. Photos before and after. Plain-English verdict. No surprises on the bill.

Crown Coating

Crown coating in Hartsdale costs $280-$450 and is appropriate when the crown structure is intact but the surface has hairline cracking or minor spalling. We use professional-grade flexible coatings from HeatShield and Copperfield that bridge small cracks while remaining vapor-permeable - critical in Hartsdale’s climate, where trapped moisture behind an impermeable sealant accelerates damage. This is not a permanent fix for a crown that has lost structural integrity. We’ll tell you straight which category yours falls into, with camera evidence you can see for yourself. Sometimes coating buys you five to seven years. Sometimes the crown is too far gone and coating would be a waste of your money. We’ll say so.

Multi-Flue Cap

Multi-flue cap installation in Hartsdale runs $420-$780 and is the correct solution for most of the village’s two-flue masonry stacks. A single cap covering both flue openings eliminates the gap between separate caps where water and debris collect, and it prevents the scenario we see constantly: one flue capped, the other open and orphaned, venting into your attic or your neighbor’s living space. We fabricate multi-flue caps from Copperfield and Famco stock to your chimney’s exact dimensions, with screening sized to keep animals out without restricting draft. On attached housing off Secor Road and the older streets near the Metro-North station, a multi-flue cap is often the only way to bring a shared stack into compliance with Town of Greenburgh and Westchester County codes.

Custom Cap

Custom cap fabrication in Hartsdale starts at $580 and ranges to $1,200 for copper or ornate designs on historic properties. Some Hartsdale Tudors have chimney profiles that don’t accommodate stock caps - corbelled tops, unusual flue spacing, or decorative brickwork that a standard cap would obscure or damage. We measure, sketch, and fabricate custom caps that protect the flue while respecting the architecture. Copper weathers to that green patina you see on Hartsdale’s older homes. Stainless stays bright. Both outlast the galvanized caps you’ll find at hardware stores by decades.

Trusted Brands We Service in Hartsdale

We stock and install professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes, no special-order delays that leave your flue open for weeks. For Hartsdale’s typical two-flue stack, we usually have the correct multi-flue cap or crown repair materials on the truck. If your job requires custom fabrication, we coordinate with Copperfield’s regional warehouse for turnaround measured in days, not weeks. These are the brands that professional sweeps specify. They’re the brands we trust on our own homes.

Common Chimney Cap & Crown Problems We See in Hartsdale Homes

• Orphaned second flue in a shared stack. Hartsdale’s 1920s-1940s housing often contains two flues in one masonry mass, with the second flue abandoned when coal or oil heat converted to gas. That opening sits uncapped, letting rain in and exhaust migrate sideways into your firebox through cracked tiles. Town of Greenburgh inspectors flag it before closing.
• Neighbor’s appliance venting into your stack. On attached properties - common near the Metro-North corridor - a shared chimney mass means your neighbor’s water heater or furnace may exhaust into an uncapped flue that connects to yours. Cross-contamination, not just weatherproofing. We’ve found carbon monoxide traces in fireboxes from exactly this condition.
• Flat crowns ponding meltwater. Original crowns on Hartsdale’s century-old chimneys were often poured with insufficient slope. Water sits, freezes, expands, and spalls the concrete. By March the crown looks like a crumbling sidewalk. The damage runs down through the top mortar courses and into the flue liner.
• Missing or rusted original caps on furnace flues. The fireplace flue got a cap because you can see it from the street. The furnace flue, tucked behind or smaller, was forgotten. Squirrels nest. Rain rusts the damper. Eventually the flue liner deteriorates enough that a simple cap installation becomes a liner replacement job. Catch it early and it’s $220. Wait, and it’s $2,400.
