We’ve been driving to North Hills since 1984. We know the winding roads off Searingtown Road, the estate sections near the Long Island Sound, and the particular way the salt-laden wind off the water hits chimneys on the eastern exposures. Homes here aren’t standard suburban construction. They’re sprawling custom builds from the 1940s through the 1970s, many with multiple fireplaces, multi-flue stacks, and original masonry that has endured fifty to eighty years of freeze-thaw cycles. That history matters when we’re diagnosing what your chimney needs. Our Chimney Cap & Crown team treats every job like the unique repair it is.
Why Hearthstone Chimney Co. of New York City Is North Hills’s Preferred Chimney Cap & Crown Company
North Hills homeowners call us back because we document what we find. Every inspection ends with photos you can see and a plain-English verdict - no jargon, no scare tactics. We’ve earned that trust over 42 years by showing up when we say, standing behind our work with the 90-Day Done Right Promise in writing, and never surprising anyone on the bill.
Our response time to North Hills is typically same-day or next-day. We’re familiar with the village’s building department requirements and the specific challenges of working on estate properties with mature landscaping and limited access. Our technicians are background-checked, uniformed, and trained to work cleanly on high-end homes where the details matter.
We recently serviced a 1960s colonial on Searingtown Road where the original concrete crown had cracked and was allowing water to seep into the flue, staining the living room ceiling. We installed a custom copper multi-flue cap and applied a CrownCoat sealant to extend the life of the aging masonry. The homeowner told us three other companies had quoted replacement of the entire chimney top without explaining why a targeted repair would suffice. We don’t work that way.
Our Chimney Cap & Crown Services in North Hills
Custom Cap Installation
Many North Hills estates were built with chimneys that don’t match standard catalog sizes - oversize flues, unusual pitches, or architectural details that require fabrication. We measure on-site and source custom caps in copper, stainless steel, or galvanized steel from Copperfield and Famco to fit exactly. A custom cap in North Hills typically runs $480-$920 installed, depending on metal choice and complexity. The alternative is a poorly fitted stock cap that gaps, rattles, and leaks within a season.
Multi-Flue Cap Installation
The large homes common in North Hills often have double or triple flues serving multiple fireplaces or a fireplace and furnace combination. Individual flue caps leave gaps where rain and debris enter, and they don’t protect the crown itself. A unified multi-flue cap covers the entire chimney top, shielding the crown and all flues in one assembly. These installations range from $620-$1,150 in North Hills, with copper at the higher end and stainless steel in the middle. We size and secure them to withstand the nor’easters that blow through off Long Island Sound.
Crown Repair
Original poured concrete crowns on North Hills homes from the 1940s-1970s are past their designed lifespan. Freeze-thaw cycling, combined with salt-laden air from nearby waterways, accelerates spalling and cracking faster than in more inland Nassau County communities. Crown repair involves removing loose material, rebuilding with proper slope and overhang, and sealing the surface. Typical crown repair in North Hills runs $380-$650. If the crown has failed completely and allowed water into the flue structure, partial rebuild may be necessary.
Crown Coating
For crowns with minor cracking but sound structural integrity, we apply professional-grade flexible sealant - CrownCoat or equivalent - that bridges hairline cracks and prevents water penetration. This is a cost-effective preventive measure, typically $280-$420 in North Hills, and we often pair it with cap replacement to protect the entire chimney top. It’s not a substitute for rebuilding a severely deteriorated crown, but it can add years of service to sound masonry.

Trusted Brands We Service in North Hills
We stock and install caps, crowns, and flashing components from Gelco, Olympia Chimney, and Copperfield - brands that manufacture to professional specifications, not the thin-gauge hardware-store equivalents that dent in the first hailstorm. For North Hills customers, this means we can often complete cap and crown work in one visit without waiting for special orders. Our trucks carry common sizes and custom-order details for faster turnaround on fabricated pieces. The materials cost more than builder-grade substitutes. They also last.
Common Chimney Cap & Crown Problems We See in North Hills Homes
- Original poured concrete crowns crack from freeze-thaw cycles. North Hills’s position between Long Island Sound and the Atlantic exposes chimneys to humid winters and frequent freeze-thaw cycling that inland Nassau County doesn’t experience at the same intensity. Water enters hairline cracks, expands when it freezes, and progressively destroys the crown from the top down.
- Multi-flue chimneys often lack a unified cap. Many estate homes were built with multiple flues but never fitted with a proper multi-flue cap. Individual flue caps or, worse, exposed flue openings allow rain directly onto the crown and into the flue system. We see this constantly in the older sections near Searingtown Road.
- Gas conversion inserts leave oversized flues uncapped. Many North Hills fireplaces were converted to gas in the 1980s and 1990s, but the original oversized masonry chimneys were rarely fitted with proper caps or liners. Owners assume “it’s not wood-burning anymore, so it’s fine.” It’s not. Uncapped flues create draft problems, moisture accumulation, and hidden carbon monoxide risk that a proper inspection should always flag.
- Salt-laden air accelerates metal cap corrosion and brick spalling. The maritime air that gives North Hills its character also eats galvanized steel caps in five to seven years and accelerates mortar joint erosion on exposed brick. Stainless steel or copper caps are the practical long-term choice here, not a luxury.

FAQs - Chimney Cap & Crown in North Hills
North Hills crowns crack primarily from decades of freeze-thaw cycling combined with salt-laden maritime air that accelerates masonry deterioration. The original poured concrete crowns on 1940s-1970s estate homes were never designed to last eighty years, and many have never been maintained. Water enters micro-cracks, freezes, expands, and progressively destroys the crown from the surface inward. If you’re seeing ceiling stains or spalling brick below the crown, the damage is already active. Call (855) 950-3861 for a free inspection and upfront estimate.
Yes, and possibly more urgently than a wood-burning fireplace. Gas conversions in North Hills often left original oversized masonry flues uncapped and unlined. Without a cap, rain enters continuously, accelerating liner deterioration and creating moisture accumulation that interferes with proper draft. An uncapped gas flue is also an entry point for animals and debris that can block exhaust and create carbon monoxide hazard. We inspect these conversions specifically for cap, liner, and draft compatibility. Call (855) 950-3861 to schedule - estimates are free.
Yes. We fabricate and source custom copper caps from Copperfield that can be coordinated with existing copper or aged metal roofing common on North Hills estates. We match patina stage where possible, or specify new copper that will weather to match over time. Custom copper caps run $680-$1,150 installed depending on size and complexity. We photograph your existing roof detail, specify the fabrication, and install with concealed fasteners that don’t compromise the roofing. Call (855) 950-3861 to arrange a measurement visit.
We measure all flue openings and the total chimney top dimension, fabricate a unified cap with proper clearances, and secure it with masonry anchors and a storm-proof fastening system. The cap extends past the crown edge to shed water, and includes screened sides for ventilation without animal entry. Most double-flue installations in North Hills take two to three hours and are completed in one visit. Stainless steel multi-flue caps run $620-$950; copper runs $780-$1,150. Call (855) 950-3861 for exact pricing on your configuration.
You generally cannot see liner deterioration from the ground or even from the fireplace opening. In North Hills, where many estate homes have original terra-cotta clay tile liners now fifty to eighty years old, we use Level-2 camera inspection to document liner condition. We lower a camera the full flue length and photograph cracks, gaps, spalling, or missing tiles that water infiltration through a failed crown has accelerated. You see the photos. We explain what they mean. If the liner is compromised, cap and crown repair must be coordinated with liner restoration to prevent recurring damage. Call (855) 950-3861 to schedule camera inspection - it’s the only way to know for certain.
