We’ve been driving to Bethpage for over 42 years, and we know the chimneys here better than our own. The post-war Cape Cods off Stewart Avenue, the ranch houses clustered near the Bethpage State Parkway, the split-levels along Hicksville Road - they share the same story. Original brick chimneys built for oil heat, now serving gas or wood, with crowns and caps that have taken sixty-plus winters of freeze-thaw punishment. Our crews are background-checked, uniformed, and carry professional-grade materials from Gelco, Olympia Chimney, and Famco so we don’t make a second trip.

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

Bethpage homeowners don’t call us once. They call us for their house, then their daughter’s house in Levittown, then their neighbor who watched our truck sit in the driveway while we photographed every crack and explained the verdict in plain English. That’s how a craftsman-built company grows in a town like this - no billboards, just word from people who’ve been burned before and won’t be again.

Our 90-Day Done Right Promise is backed in writing with no arguing. If the crown coating we applied on your Hicksville Road ranch cracks through next thaw, we come back. No paperwork to dig up, no runaround. We’ve been answering the phone with a live person 24 hours a day, 7 days a week for four decades because a chimney leak at midnight on a February weekend is not a voicemail situation.

Dispatch and scheduling are coordinated from our New York City office, but our crews live and work Nassau County. They know that a nor’easter rolling up from the Atlantic, roughly 12 miles south, hits Bethpage harder than towns further inland. They know to check for salt-laden moisture intrusion behind the flashing. And they know that most Bethpage cap jobs aren’t just cap jobs - the oversized oil-era flue underneath usually tells a bigger story.

Our Chimney Cap & Crown Services in Bethpage

Custom Cap Installation

Off-the-shelf caps from the hardware store don’t fit Bethpage’s chimneys. The original oil-era flue tiles in these 1950s Cape Cods and ranches are oversized by modern standards, so a standard 8×13 or 13×13 cap sits loose, shifts in a south-shore wind, and funnels rain straight onto a already-compromised crown. We measure the actual flue opening, account for any adjacent venting, and fabricate or source a custom cap - often from Copperfield or Olympia Chimney - that seats properly and vents correctly. For multi-fuel chimneys where an old oil flue now serves gas and a wood stove shares the firebox, we size multi-flue caps that protect both sides without choking draft.

Cap Replacement

Most Bethpage homeowners don’t notice their cap has failed until water spots appear on the ceiling near the chimney breast or the fireplace smells like wet ash after rain. By then the crown underneath has been soaking for one or two seasons. We replace rusted, wind-damaged, or improperly fitted caps with professional-grade models from Gelco or Famco, and we always inspect the crown surface beneath before we bolt down. A new cap on a cracked crown is money thrown away. We’ll show you the photos. Then you decide.

Crown Repair

The concrete crown is the chimney’s umbrella. On Bethpage’s 60-to-75-year-old brick chimneys, original builder-grade crowns are typically 2-inch unreinforced slabs with no overhang and no drip edge - fine for 1955, inadequate for decades of central Nassau freeze-thaw. Water infiltrates hairline cracks, expands on the first hard freeze, and spalls off surface concrete in layers. We repair structurally sound crowns with proper mortar formulation and slope correction. When the damage is too deep for patching, we tell you straight and quote rebuild rather than sell you a temporary fix.

Crown Coating

For crowns with surface cracking and minor spalling but intact structural integrity, we apply Gelco CrownCoat or HeatShield CrownSeal - flexible, waterproof coatings designed to bridge hairline cracks and shed water without trapping vapor. This isn’t paint. It’s a masonry-specific formulation that breathes slightly while blocking liquid water, critical for Bethpage chimneys where interior condensation from oversized gas flues keeps the crown underside damp year-round. We prep the surface, fill voids, and apply two coats. Done right, it adds 10-15 years to a crown that would otherwise need full rebuild. And we stand behind it with our 90-Day Done Right Promise - in writing, no arguing.

Multi-Flue Cap

Bethpage’s multi-fuel chimneys - common in homes where a gas insert replaced the oil burner but the family kept the fireplace for wood - need multi-flue caps that cover all flue openings with proper clearance and draft. A single-flue cap on a multi-flue chimney leaves the other opening exposed, or worse, creates downdraft problems that push smoke into the house. We measure center-to-center flue spacing, account for chimney pot or exterior dimensions, and set multi-flue caps from Olympia Chimney or custom-fabricated Copperfield units that fit like they were made for your chimney. Because they were.

Trusted Brands We Service in Bethpage

We don’t use builder-grade substitutes. Our trucks carry professional-grade caps, crowns, and coating materials from Gelco, Olympia Chimney, and Famco - brands that sweeps have trusted for decades because they survive what Nassau County weather throws at them. For custom or oversized applications, we work with Copperfield to fabricate caps that fit Bethpage’s non-standard flue openings. We stock common sizes locally, so most Bethpage jobs don’t wait on shipping. When we quote a job, the materials are already in the warehouse or on the truck. No surprises on the bill. The number on the estimate is the number on the invoice.

Common Chimney Cap & Crown Problems We See in Bethpage Homes

• Freeze-thaw crown destruction on original 1950s masonry. Central Nassau’s winters deliver repeated freeze-thaw cycles that are particularly punishing to 60-plus-year-old mortar joints in Bethpage’s brick chimneys. Original builder-era crowns crack, spall, and develop open voids that let meltwater run straight down the flue, feeding the interior mortar erosion caused by condensing gas flue gases.
• Loose, ill-fitting caps on oversized oil-era flues. Standard caps don’t seat properly on Bethpage’s original flue tiles, which were sized for oil furnaces and are now 25-40% too large for gas inserts. The cap shifts, gaps open, and coastal salt-laden rain from nor’easters drives directly into the smoke chamber.
• Wood-stove flues unprotected by proper caps. Bethpage homeowners who burn wood as primary or supplemental heat generate creosote-loaded flue gases that cool rapidly in an oversized flue. Without a properly sized cap to protect the crown and maintain draft, rain mixes with acidic condensate and creosote residue, accelerating crown deterioration from the top while interior condensation attacks from below.
• Hidden flue damage visible only after cap removal. Because thousands of Bethpage’s post-WWII Cape Cods and ranches swapped oil furnaces for gas inserts but kept their oversized oil-era flue tiles, sweeps here routinely find chimneys that need a full reline rather than the cleaning the homeowner called for. The underdrafting flue condenses year-round and eats mortar from the inside. For cap-and-crown work this means a Bethpage cap job usually can’t be quoted in isolation: the crown and the flue opening are often the first visible symptom of an oversized, wet flue underneath.
