We’ve been working on East Hills chimneys since the 1980s, back when many of these homes were barely twenty years old. We know the village’s post-war colonials and split-levels along Harbor Hill Road and Glen Cove Road, the Tudors tucked behind North Court, and the bi-levels near the East Hills Park boundary. Our trucks carry Famco and Copperfield caps in common sizes, DuraFlex liner materials, and HeatShield crown coating so we don’t waste your time with return trips for parts. When salt air from Long Island Sound has done its work, we’re familiar with the damage pattern. And we see it often.

Our Chimney Cap & Crown Services in East Hills
Crown Repair
Crown repair is what we do most often in East Hills, and there’s a reason. The original concrete crowns on these 1950s-1970s masonry chimneys were poured with too little slope or too much water in the mix, and fifty years of North Shore freeze-thaw cycles have turned them into shallow bowls that hold water instead of shedding it. Salt-laden moisture drifting inland from Long Island Sound accelerates the spalling. We cut out the damaged concrete, form a proper crown with adequate overhang and drip edge, and seal it with an elastomeric waterproof coating. On a colonial near Bryant Avenue last winter, we removed three inches of saturated crown and rebuilt it to shed nor’easter runoff. The homeowner had been patching it with caulk for years. That never works.
Multi-Flue Cap
Many East Hills homes have multi-flue chimneys serving a fireplace, a furnace, and a water heater. The affluent character of the village means these complex systems are common, and each flue needs its own protection. A single oversized cap leaves gaps where rain and animals enter inactive flues. We measure each flue separately and fabricate multi-flue caps from stainless steel or copper, with screened sides for ventilation and a lid that sheds water clear of the masonry. For gas-converted flues, we install liner caps that seal properly to the new stainless insert. This is critical. Unlined gas flues left open after 1980s conversions are a code deficiency Nassau County home inspectors flag during real estate transactions, and we’ve handled dozens of last-minute jobs before closing.
Crown Coating
When the crown damage is surface-level but the structural concrete is sound, crown coating is a cost-effective alternative to full rebuild. We clean the crown thoroughly, repair minor cracks with HeatShield refractory mortar, then apply a flexible waterproof elastomeric sealer rated for freeze-thaw cycling. In East Hills’s coastal climate, this buys you years of protection against salt-air intrusion and spalling. We recommend coating every five to seven years as preventive maintenance, especially on chimneys within a mile or two of Long Island Sound. It’s not a permanent fix for a crown that’s already crumbling, but for early-stage deterioration, it’s a square deal.
Cap Installation & Replacement
New cap installation in East Hills runs $380-$890 depending on size, material, and whether we need to install or extend a flue liner. Galvanized steel caps rust out here in seven to ten years. We stock stainless and copper options from Famco and Copperfield that last decades. Custom caps for oversized or irregular flues take a few days to fabricate, but standard sizes go on same-day. If your cap is missing, damaged, or improperly sized, water is entering your flue every time it rains. That water freezes, expands, and destroys mortar joints from the inside out.

Common Chimney Cap & Crown Problems We See in East Hills Homes
- Salt-laden moisture from Long Island Sound accelerates crown cracking and spalling, especially on homes near Bryant Avenue. The chloride in that air penetrates porous concrete, corrodes reinforcing wire, and causes the surface to flake off in sheets. We’ve rebuilt crowns on thirty-year-old homes that looked sixty.
- Freeze-thaw cycles during North Shore nor’easters cause mortar joints around the cap to erode, allowing water into the flue. Each freeze expands the crack; each thaw lets more water in. By March, a hairline crack can be a half-inch gap.
- Unlined gas-converted flues lack proper caps, leading to downdrafts and moisture intrusion that corrode the clay liner joints. This is the hidden legacy of East Hills’s 1980s-90s oil-to-gas conversions. The oversized flue was never meant for a modern gas appliance, and without a proper liner cap, cold air drops straight down the chimney.
- Original galvanized caps rust through at the seams, particularly on south-facing chimneys that get the most weather. Once the seam fails, the cap becomes a funnel that directs water into the flue instead of away from it.

FAQs - Chimney Cap & Crown in East Hills
Salt-laden moisture from Long Island Sound accelerates concrete spalling and rebar corrosion, while North Shore freeze-thaw cycles open cracks wider each winter. Inland towns on Long Island see similar cold but without the coastal chloride load, so their crowns last roughly 30% longer. If your crown is showing surface flaking, it’s time to act before the freeze-thaw cycle destroys the structural layer. Call (855) 950-3861 for a free inspection and estimate.
Yes, if your chimney serves more than one appliance. Most East Hills colonials and Tudors have multi-flue chimneys handling a fireplace plus furnace or water heater, and a single cap leaves inactive flues exposed to rain and animals. We measure each flue separately and fabricate a cap that seals every opening while maintaining proper draft. Call (855) 950-3861 and we’ll assess your configuration.
A new cap helps, but the root problem is usually the unlined oversized flue left from an oil-to-gas conversion. The cap blocks direct downflow, but without a properly sized liner and liner cap, the flue remains too large for the appliance’s exhaust volume. We install DuraFlex stainless liners with matching caps that solve both the draft and the moisture intrusion. Call (855) 950-3861 for an inspection that includes a Level-2 camera evaluation of the flue interior.
Galvanized steel caps last 7-10 years here; stainless or copper caps last 20+ years with proper maintenance. We recommend inspecting the cap annually, especially after nor’easters, and replacing it at first sign of seam separation or significant rust. The cost of a new cap is minor compared to the water damage it prevents. Call (855) 950-3861 for an exact quote on your flue size.
Yes, if the structural concrete is sound and cracks are less than one-eighth inch wide. We clean the surface, repair minor cracks with HeatShield refractory mortar, and apply a flexible elastomeric sealer rated for freeze-thaw cycling. In East Hills’s climate, this treatment is effective for five to seven years as preventive maintenance. If the crown is already crumbling or the reinforcing wire is exposed, full rebuild is the only lasting solution. Call (855) 950-3861 and we’ll give you a plain-English verdict with photos you can see.
We replaced a deteriorated crown and installed a multi-flue copper cap on a 1960s Tudor on North Court, where salt air from Long Island Sound had spalled the mortar and rusted the old galvanized cap. The gas-converted flue required a custom stainless liner cap, and we coated the new crown with a waterproof elastomeric sealer to withstand nor’easters. That job is typical of what we see in East Hills: multiple failure modes from age, conversion history, and coastal exposure, all needing to be addressed together so the homeowner doesn’t face another repair in two years.
Chimney cap and crown work is not cosmetic. A failed crown lets water into the chimney structure, and that water destroys the chimney from the inside. In East Hills, where the housing stock is fifty to seventy years old and the coastal climate is unforgiving, the damage accelerates faster than many homeowners realize. We document what we find, explain what it costs, and stand behind the repair with the 90-Day Done Right Promise in writing. No arguing. If it’s not right, we come back.
Call (855) 950-3861 now. A live person will answer, 24 hours a day, 7 days a week. We’ll schedule your free estimate, arrive when we say, and give you the straight story on what your chimney needs. Done right, and we stand behind it.
