Why Hearthstone Chimney Co. of New York City Is New Hyde Park’s Preferred Chimney Cap & Crown Company
We’ve been driving to New Hyde Park since 1984, back when most of these postwar Cape Cods and colonials were still heated by oil and their chimneys were working as designed. Forty-two years in this trade means we’ve watched the whole hamlet convert to gas, and we’ve seen what those under-fired flues do to crowns and caps over time. Our Chimney Cap & Crown team documents every inspection with photos you’ll see yourself and a plain-English verdict - no engineer-speak, no scare tactics.
New Hyde Park homeowners don’t call us for flash. They call because we show up when we say, our technicians are background-checked and uniformed, and our 90-Day Done Right Promise is in writing with no arguing. If it’s not right, we come back.

Our Chimney Cap & Crown Services in New Hyde Park
Custom Cap Installation for Acreage Properties and Detached Workshops
New Hyde Park’s remaining acreage lots - many still traceable to the old nursery farms - hold detached workshops, barn conversions, and outbuildings with chimney systems that standard big-box caps simply don’t fit. These structures often run multiple flues for boilers, furnaces, and wood stoves, with openings too wide or irregular for off-the-shelf solutions. We measure on-site, fabricate to spec, and install heavy-gauge custom caps from Famco and Copperfield that span the full width without leaving gaps where water and wildlife slip through. A cap that doesn’t fit is worse than no cap at all. We make sure it fits.

Multi-Flue Cap Installation and Replacement
Homes near the Jericho Turnpike corridor and the larger lots south of Hillside Avenue frequently have two or three flues clustered on a single chimney - legacy of oil-to-gas conversions that added equipment without consolidating venting. Multi-flue caps require precise sizing and proper height clearance to maintain draft for each appliance. Our technicians carry professional-grade options from Gelco and Olympia Chimney, and we size them so each flue draws independently without backdrafting into the others. In New Hyde Park’s damp maritime air, a properly fitted multi-flue cap is what stands between your flue tiles and the spalling that follows years of freeze-thaw saturation.

Crown Repair and Rebuilding
The mortar crown is the chimney’s roof - a sloped cap of concrete or mortar that sheds water off the flue and onto the roof plane. On New Hyde Park’s 60- to 80-year-old chimneys, these crowns are often the first thing to fail. The flat Hempstead Plain exposes tall chimneys to full wind and weather, and the temperature oscillation around freezing through January and February opens hairline cracks into full fractures. Once water penetrates, it reaches the freeze-thaw cycle inside the masonry, and the damage accelerates. We repair minor cracking with HeatShield crown coating, a professional-grade refractory compound that seals and slopes the surface. For crowns that have crumbled or separated from the flue tiles, we remove and pour new crowns with proper overhang and drip edges. Done right - and we stand behind it.

Crown Coating for Preventive Maintenance
Not every cracked crown needs rebuilding. If we catch it early - before water has saturated the brick below - a crown coating application can add ten to fifteen years of service. This is particularly valuable on New Hyde Park’s acreage properties, where workshop chimneys may go years between inspections. We recently replaced a crumbling crown and installed a multi-flue custom copper cap on a detached workshop off Jericho Turnpike whose three flues - serving a boiler, furnace, and wood stove - had cracked from decades of under-fired gas condensation following an oil-to-gas conversion; we used HeatShield crown coating and a Famco heavy-gauge cap to ensure a single-trip fix for the self-reliant homeowner. That’s the kind of job we built this company to handle.

Common Chimney Cap & Crown Problems We See in New Hyde Park Homes
- Crowns crack from freeze-thaw on tall, exposed chimneys serving detached outbuildings. New Hyde Park’s acreage properties put workshop chimneys above the tree line and into full wind exposure on the Hempstead Plain. The freeze-thaw cycling through January and February progressively fractures aged mortar crowns, and the acidic condensation from under-fired gas furnaces after oil-to-gas conversions accelerates the deterioration from the inside out.
- Oversized flues on acreage properties collect more debris and moisture, corroding standard caps. Chimneys built for 275,000-BTU oil burners now venting 60,000-BTU gas equipment move too little air to stay dry. Moisture lingers, debris accumulates, and the standard cap that fit the original flue now sits wrong or rusts through. Heavy-duty custom caps are needed to span large multi-flue openings and shed water at the volume these chimneys see.
- Self-reliant homeowners delay maintenance until water damage appears in their workshop or garage. We understand the impulse - these are hands-on properties, and the owner who maintains their own equipment hates calling for help. But by the time staining shows on interior walls or spalling brick is visible from the ground, the crown has been failing for years and the repair has graduated from coating to full rebuild. Annual inspection costs far less.
- Informal additions complicate cap and crown sizing. Raised capes, finished basements with added flues, and workshop conversions have left many New Hyde Park chimneys with mismatched flue heights and diameters. A cap that covers one flue may suffocate another. Our Level-2 camera inspections map the full system before we quote, so the solution fits what you actually have - not what a standard spec sheet assumes.

FAQs - Chimney Cap & Crown in New Hyde Park
Workshop chimneys on New Hyde Park’s acreage properties are often taller, more exposed, and fitted with larger or multiple flues than standard residential chimneys. Standard caps don’t span the opening, don’t withstand the wind load on the Hempstead Plain, and don’t accommodate the debris volume that oversized flues collect. We use heavy-gauge custom or multi-flue caps from Famco and Copperfield, fabricated to the actual dimensions of your flue cluster. Call (855) 950-3861 and we’ll measure on-site - estimates are free.
It changes everything about how your flue operates. A flue sized for a 275,000-BTU oil burner now venting a 60,000-BTU gas furnace stays too cool to draft properly, and the acidic condensation that results attacks mortar crowns and clay flue tiles from the inside. The cap that worked for hot oil exhaust may now trap moisture, and the crown may be deteriorating faster than visible from the ground. We inspect with a camera, show you the photos, and recommend a cap and crown solution sized for your actual post-conversion conditions. Call (855) 950-3861 for a free second opinion on any written estimate.
Nassau County requires a permit for chimney relining, but crown replacement and cap installation typically do not trigger permitting if the work is repair-in-kind on an existing flue. If our Level-2 inspection reveals that relining is necessary - common after oil-to-gas conversions on these 60- to 80-year-old chimneys - we handle the permit application as part of the job. We know the Nassau County process and the backlog it’s carried since the conversion wave began. Call (855) 950-3861 and we’ll tell you exactly what your specific chimney requires.
We can, but we won’t until we’ve inspected the flue with a camera. Capping a chimney with active creosote buildup, nesting debris, or deteriorated flue tiles traps the problem and accelerates damage. Our $89 Seasonal Tune-Up includes cleaning and inspection; if we find the flue sound, we cap it same visit. If it needs repair first, we show you the photos and quote the full scope. No cap goes on blind - that’s not how we work. Call (855) 950-3861 to schedule.
For New Hyde Park’s exposed acreage chimneys, we specify heavy-gauge stainless steel or copper from Famco or Copperfield - never the lightweight galvanized products that box stores sell. Stainless resists the salt-laden maritime air off Long Island Sound; copper weathers to a protective patina and lasts 50+ years on properties where the owner plans to stay. The critical factor isn’t just material, though - it’s gauge and fit. A heavy-gauge cap that doesn’t fit your flue cluster is still wrong. We measure, we fabricate to spec, we install. Call (855) 950-3861 for an exact quote on your chimney.
