Fast, Reliable Chimney Cap & Crown Across Greenburgh
Chimney cap and crown repair in Greenburgh typically runs $340-$1,200 depending on whether we’re sealing a hairline crack or pouring a new concrete crown, and most jobs are completed in a single visit. We’re Hearthstone Chimney Co., and we’ve been driving to Greenburgh homes since 1984 - long enough to know which Irvington Victorians have the oversized multi-flue chimneys that were never properly crowned after coal-to-gas conversions, and which Hartsdale Colonials need Gelco caps sized for flue tiles that don’t match modern standards. If you’re seeing water stains on your firebox, hearing debris tumble down the flue, or noticing mortar crumbs in your yard after a freeze, call (844) 803-1545. A live person answers, 24 hours a day, and we’ll give you a free estimate with upfront pricing - the number we quote is the number on the invoice.
Why Hearthstone Chimney Co. Is Greenburgh’s Preferred Chimney Cap & Crown Company
We’ve worked on chimney caps and crowns in Greenburgh for over four decades. That means we’ve seen what the Hudson River moisture does to porous brick after a century of freeze-thaw cycles, and we know that a crown poured without proper slope and drip edge will fail faster here than in drier inland Westchester towns.
Our customers in the 10533 ZIP - Irvington especially - tend to stay in their homes for twenty or thirty years. They remember the contractor who didn’t return their call, and they notice when a technician shows up in a marked van, in uniform, with a camera and a plain-English explanation of what they’re looking at. That’s who we send. Every technician is background-checked, and every job is documented with photos you can see and a written verdict you can understand.
Most cap and crown jobs in Greenburgh are finished in one visit. We don’t leave you with a tarp and a promise to return. We also don’t surprise you on the bill - our upfront pricing means you approve the number before we start.
And if something isn’t right, our 90-Day Done Right Promise applies: we come back, no paperwork, no arguing. In writing. We’ve been in business since 1984 because we plan to be here in thirty more years, and that only works if Greenburgh homeowners trust us to stand behind the work.
Our Chimney Cap & Crown Services in Greenburgh
Cap Installation
New cap installation in Greenburgh runs $340-$680 for standard single-flue stainless steel models, and $580-$1,150 for multi-flue caps on the large Victorian and Edwardian chimneys common in Irvington and the river-facing hamlets. These older homes often have flue tiles that don’t align with off-the-shelf sizes, so we measure with a level-2 camera inspection first and fabricate or source caps that fit precisely. A proper cap keeps Hudson River-driven rain out of your flue, stops squirrels and starlings from nesting, and prevents the downdrafts that blow smoke into living rooms on windy valley days. We install caps from Gelco and Olympia Chimney, both brands that hold up to Greenburgh’s wet winters without corroding through in five years.
Cap Replacement
Cap replacement in Greenburgh costs $290-$620 depending on whether we’re removing a rusted-through builder-grade unit or a failed DIY installation. Many homes near the Dobbs Ferry border have caps that were installed without proper clearance or fastening, and the first strong wind off the Hudson sends them into the yard. We document the existing flue condition with photos, remove the old cap without damaging terra-cotta tiles that may already be brittle from age, and install a replacement with stainless steel fasteners and proper screen height to allow adequate draft. If your flue liner is also deteriorated, we’ll flag it during the same visit - our Chimney Liner & Rebuild in Greenburgh crew can address it without scheduling a second trip.
Crown Repair
Crown repair in Greenburgh typically costs $420-$890 for crack sealing and resurfacing, and $780-$1,200 for partial rebuilds where the concrete has spalled down to the brick below. The crown is the concrete slab that tops your chimney, and it’s the first line of defense against water intrusion. In Greenburgh’s river-valley climate, crowns absorb persistent moisture that accelerates spalling once January temperatures drop below freezing. We’ve repaired crowns on homes along Route 9 and in the hills above Hartsdale where the original pour was flat or missing an overhang, allowing water to run straight down the brick faces. Our repairs use professional-grade crown coat materials with flexible polymers that move with the masonry through freeze-thaw cycles rather than cracking again the following winter.
Crown Coating
Crown coating in Greenburgh runs $340-$580 for application over structurally sound concrete, and is our recommended preventive service for chimneys showing early hairline cracking but no major spalling. We use HeatShield CrownCoat or equivalent professional-grade flexible sealers, not the hardware-store brush-on products that peel within two seasons. The coating is applied after cleaning and light grinding of the existing surface, and it carries a proper slope to shed water toward the drip edge. For Greenburgh homeowners with original crowns on 1920s Tudors or Colonial Revivals, this can add ten to fifteen years of service before a full rebuild is necessary. We inspect the crown as part of every Chimney Cleaning & Sweep in Greenburgh visit, so you’ll know when coating is still viable and when it’s time to pour new concrete.

Trusted Brands We Service in Greenburgh
We work exclusively with professional-grade materials - no builder-grade substitutes that fail halfway through a Greenburgh winter. For caps, we stock and install Gelco and Olympia Chimney stainless steel units in common sizes, with custom fabrication available for the oversized flue configurations found in Irvington’s Victorian housing stock. For crown repair and coating, we use HeatShield flexible crown products that bond to existing concrete and remain pliable through freeze-thaw stress. Famco hardware and fasteners round out our inventory for secure, corrosion-resistant installations. We keep these parts on our trucks, which means most Greenburgh jobs don’t wait on a warehouse order. You get the repair done right, and you get it done promptly.
Common Chimney Cap & Crown Problems We See in Greenburgh Homes
- River-driven moisture accelerating crown deterioration. Greenburgh’s position in the Hudson River Valley means chimneys absorb more ambient moisture than inland Westchester properties. When January temperatures plunge below freezing, that moisture expands inside porous brick and concrete, causing spalling and mortar erosion that shows up as sand-like debris in your fireplace or yard.
- Missing or improperly sloped crowns on converted coal chimneys. Many Irvington and Dobbs Ferry homes have large multi-flue chimneys that were never properly crowned after mid-century fuel conversions. The original caps were removed or never installed, leaving the flue tops exposed to direct rainfall and the flue cavities open to animal intrusion.
- Failed DIY cap installations with inadequate fastening. We’ve removed dozens of big-box store caps from Greenburgh chimneys where the homeowner or a handyman used incorrect fasteners or skipped the storm collar. The first sustained wind off the Hudson lifts these loose caps, often damaging flue tiles when they go.
- Freeze-thaw damage concentrated on south-facing chimney exposures. In Greenburgh’s older neighborhoods, chimneys with southern exposure experience more dramatic daily temperature swings in winter. The repeated expansion and contraction opens cracks in crowns and mortar joints faster than on shaded or north-facing structures, something we account for during inspection and repair planning.

Greenburgh pricing is generally comparable to other Westchester River Towns like Dobbs Ferry and Hastings-on-Hudson, though the large multi-flue chimneys common in Irvington can run toward the higher end of our ranges due to custom cap sizing and extensive crown surface area. Inland Westchester towns with newer housing stock and standard single-flue chimneys sometimes see lower average costs. We don’t adjust pricing based on your address - the estimate reflects the actual work, materials, and time required for your specific chimney.
All our cap and crown work is covered by the 90-Day Done Right Promise - if anything isn’t right, we come back and make it right, in writing, with no paperwork and no arguing. This applies to every Greenburgh job regardless of size. Manufacturer warranties on Gelco, Olympia Chimney, and HeatShield products run longer and are also honored. We’re a company that’s been in business since 1984; we plan to be here to stand behind your repair for decades to come. Call (844) 803-1545 with any warranty question.
