We’ve been driving out to Port Washington since 1984. We know the difference between a chimney facing Manhasset Bay and one tucked inland toward Main Street.

Our technicians are background-checked, uniformed, and trained to document every inspection with photos you’ll see and a plain-English verdict you’ll understand.
Why Hearthstone Chimney Co. of New York City Is Port Washington’s Preferred Chimney Cap & Crown Company
Port Washington homeowners call us back. They tell their neighbors. After 42 years serving Nassau County, our reputation here is built on showing up when we say, charging what we quote, and standing behind the work. Frank Calucci started this company in 1984 with the belief that a craftsman doesn’t need to oversell - the work speaks, and the guarantee backs it up.
Our 90-Day Done Right Promise is in writing, no arguing. If something isn’t right, we come back. That matters in a village where the median home age pushes 80 years and chimney problems rarely fix themselves.
We answer the phone with a live person, 24 hours a day, 7 days a week. Not a callback queue. Not an app. A real voice. Most Port Washington calls are scheduled within 48 hours, and most jobs finish in one visit with upfront pricing - the number on the estimate is the number on the invoice.
Our technicians carry professional-grade materials from Copperfield, Gelco, and HeatShield. We don’t substitute builder-grade parts and hope for the best. In Port Washington’s salt air, that distinction is the difference between a repair that lasts five years and one that lasts fifteen.
Our Chimney Cap & Crown Services in Port Washington
Crown Repair
Crown repair is our most frequent call in Port Washington, and there’s a reason. The village’s position on Manhasset Neck exposes chimneys to salt-laden air from Manhasset Bay and Hempstead Harbor simultaneously. We’ve seen concrete crowns crack and spall on the bay-facing side years before the leeward face shows any damage. Our crown repair process includes removing deteriorated concrete, forming a proper slope for water runoff, and pouring a new crown with reinforced, weather-resistant mix. We recently replaced a deteriorated crown on a 1930s Tudor chimney in the Manhasset Bay Estates neighborhood. The original concrete crown had cracked from salt-laden freeze-thaw cycles, allowing moisture to penetrate the flue tiles. We installed a custom copper cap from Copperfield and applied a waterproof crown coating to protect against future coastal exposure.
Custom Cap Installation
Port Washington’s 1920s-1950s housing stock includes chimneys built for coal and later retrofitted for oil or gas. Flue sizes vary. Standard box-store caps don’t fit. We measure on-site, fabricate or source custom caps from Copperfield and Gelco in copper, stainless steel, or galvanized steel with proper clearances and mesh screening. Copper holds up best against salt air. Galvanized steel costs less upfront but may show corrosion within five to seven years in this environment. We’ll tell you straight which makes sense for your chimney and your timeline.
Multi-Flue Cap Installation
Larger homes in the Sands Point and Manhasset Bay Estates areas often have multi-flue chimneys with two or three flues, sometimes with only one actively used. An open flue is an invitation for rain, squirrels, and starlings. A multi-flue cap covers the entire chimney top with a single protective shelter, eliminating gaps between individual caps where water pools and debris collects. We size and install multi-flue caps that vent properly while sealing out the elements - critical in Port Washington, where nor’easters drive wind-blown rain at chimney tops from October through April.
Crown Coating
For crowns with minor cracking but sound structural integrity, crown coating extends service life at lower cost than full replacement. We use professional-grade flexible coatings from HeatShield that bridge hairline cracks and shed water while allowing the crown to breathe. In Port Washington’s freeze-thaw climate, breathability matters - trapped moisture expands, cracks concrete, and starts the cycle again. Crown coating runs $350-$650 and carries the same 90-Day Done Right Promise as our rebuilds.

Common Chimney Cap & Crown Problems We See in Port Washington Homes
- Rapid crown spalling on the bay-facing side. Wind-driven salt spray off Manhasset Bay attacks the windward elevation of Port Washington chimneys first. Mortar joints deteriorate years ahead of the other three faces, creating asymmetric damage that looks minor from the street but signals deep moisture infiltration. A local technician quickly learns to check the bay-facing side first.
- Galvanized flashing corroding within five years. The persistent salt air off Manhasset Bay accelerates oxidation of metal flashing and damper hardware at a rate that homeowners who moved from inland suburbs consistently underestimate. We see leaks at the chimney-roof joint in homes where the flashing looked fine at purchase but failed three winters later.
- Unused flue liners left open to moisture and nesting animals. Multi-flue stacks common in larger Port Washington estates frequently have one active flue and one or two dormant. Without caps, rain enters, freeze-thaw cycles crack the liner, and squirrels build nests that block ventilation and create fire hazards.
- Original concrete crowns sloped flat or reversed. Many Port Washington chimneys were built with crowns that pool water rather than shed it. Combined with coastal freeze-thaw cycles, flat crowns crack within a decade. We re-pour with proper pitch and overhang to protect the brick below.

FAQs - Chimney Cap & Crown in Port Washington
Port Washington’s location on Manhasset Neck means chimneys are bombarded by salt air from Manhasset Bay and Hempstead Harbor simultaneously, causing crown deterioration and flashing corrosion to occur twice as fast as in nearby inland towns like Manhasset proper. The salt accelerates mortar joint erosion and concrete spalling, while the peninsula’s exposure to wind-driven rain from multiple directions keeps chimney tops wetter, longer. Freeze-thaw cycles do the rest. If your crown is more than ten years old, we should inspect it. Call (855) 950-3861 for a free estimate.
Yes, if you plan to stay in your home more than five years. Galvanized and zinc-coated steel caps corrode visibly within five to seven years in Port Washington’s salt air, while copper develops a protective patina and lasts decades. The upfront cost difference is typically $300-$500, but replacement labor and the risk of water damage during the corroded years make copper the better value. We’ll show you both options and let you decide. Call (855) 950-3861.
Every twelve months, preferably in early fall before the first hard freeze. Port Washington’s combination of salt air, nor’easter-driven rain, and freeze-thaw cycles means cap and crown damage can progress from hairline crack to structural failure within a single winter. Our $89 seasonal tune-up includes a Level-2 camera inspection with photos you can see and a plain-English verdict. Call (855) 950-3861 to schedule.
A flexible, breathable, waterproof coating formulated for freeze-thaw cycling and salt exposure. We use professional-grade products from HeatShield that bridge cracks up to 1/8 inch while allowing vapor transmission - critical because trapped moisture expands and fractures concrete in Port Washington’s winter temperature swings. Crown coating is not a substitute for a badly deteriorated crown, but for sound concrete with minor cracking, it adds five to ten years of service life. Call (855) 950-3861 to see if your crown qualifies.
If your Port Washington home has two or more flues and any are unused, yes. Open flues collect rain, debris, and animal nests. A multi-flue cap covers the entire chimney top with a single shelter, eliminating the gaps between individual caps where water pools and squirrels enter. This is especially important in larger homes near Manhasset Bay, where multi-flue stacks are common and the salt air makes every opening more damaging. We measure and install custom multi-flue caps in copper or stainless steel. Call (855) 950-3861 for an exact quote - estimates are free.
Port Washington occupies Manhasset Neck, a peninsula with Manhasset Bay on the east and Hempstead Harbor on the west, meaning chimneys here are flanked by salt-laden marine air from multiple directions simultaneously - dramatically accelerating mortar joint erosion, brick spalling, and flashing corrosion compared to even nearby inland Nassau County towns like Manhasset proper. The village’s dense concentration of 1920s-1950s masonry chimneys, combined with this multi-directional coastal exposure, makes repointing and crown repair far more urgent and frequent here than the regional average. This page delivers repair strategies tailored to Port Washington’s multi-directional coastal salt exposure, so you don’t have to rely on generic advice meant for inland homes.
Call (855) 950-3861 now. A live person will answer, 24 hours a day, 7 days a week. We’ll schedule your free estimate, show you photos of what we find, and give you a plain-English verdict with upfront pricing. Done right - and we stand behind it.
