We’ve been dispatching crews to North Bellmore from our New York City office for decades. We know the Cape Cods along Newbridge Road, the ranches tucked behind Jerusalem Avenue, and the split-levels near the Wantagh Parkway corridor. These homes share a common problem: chimneys built during Nassau County’s 1947-1965 suburban boom, now 60-75 years old, facing salt air that inland neighbors simply don’t deal with. Our Chimney Repair team carries the materials to fix most issues on the spot.

Why Hearthstone Chimney Co. Is North Bellmore’s Preferred Chimney Repair Company

North Bellmore homeowners don’t hire us for flashy trucks or discount coupons. They hire us because we’ve been answering the phone with a live person for over 42 years, because our 90-Day Done Right Promise is backed in writing with no arguing, and because we show them photos of their own chimney rather than asking them to trust a verbal diagnosis.

Our technicians are background-checked, uniformed, and trained to complete most repairs in a single visit. No-hassle upfront pricing means the number on your estimate matches the number on your invoice. We’ve built our reputation on being the company that plans to be in town thirty years from now, so we act accordingly on every job.

Dispatch and scheduling are coordinated from our New York City office, but our crews serve North Bellmore locally and carry the specific parts these post-WWII chimneys need. That matters when your crown is cracked and rain is forecast.

Our Chimney Repair Services in North Bellmore

Mortar Repointing

The mortar joints on North Bellmore’s 1950s and 1960s brick chimneys are reaching the end of their natural life. Salt air from the Great South Bay accelerates the degradation, and once joints begin to powder, freeze-thaw cycling from November through March opens them further. A typical mortar repointing job in North Bellmore runs $800-$1,600 for a standard single-flue chimney. We grind out the deteriorated mortar to proper depth and repoint with color-matched, vapor-permeable mortar that lets the wall breathe while keeping water out.

Spalling Brick Repair

Spalling-when the face of a brick pops off due to moisture penetration and freezing-is especially common on North Bellmore chimneys above the roofline, where salt-laden air and temperature swings hit hardest. We were called to a split-level on Bellmore Road for a Chimney Cleaning & Sweep in North Bellmore, and the moment our tech stepped onto the roof he saw the original 1950s galvanized cap flaking apart and surface rust bleeding down the crown. That cap had been sheltering a spalling brick flue and a cracked crown for years, letting salt air and freeze-thaw moisture into the very mortar joints it was supposed to protect. We swapped it for a stainless DuraFlex cap, repointed the worst joints, and applied a vapor-permeable waterproofing coat-stopping the active deterioration before it reached the flue liner. Individual brick replacement with matching salvage or new stock typically costs $150-$400 per brick area, with full rebuilding above the roofline running $1,200-$2,400.

Chimney Waterproofing

Because North Bellmore sits only 2-3 miles from the Great South Bay, salt-laden air reaches the chimneys here year-round, corroding galvanized caps, crowns, and flashing far faster than on inland Nassau County homes just five miles north and west. In practice, we replace more Chimney Cap & Crown - North Bellmore units after 8-10 years than we do on similar homes in Hicksville after 15-it’s the coastal exposure, not the age of the chimney, that drives the cycle. Our waterproofing treatment uses professional-grade, vapor-permeable sealers from Copperfield that allow the masonry to breathe while blocking liquid water and salt intrusion. A full waterproofing application in North Bellmore typically runs $450-$850 depending on chimney size and accessibility.

Flashing Repair

The intersection where your chimney meets the roof is the most leak-prone point on any home, and in North Bellmore the combination of salt air and seasonal expansion-contraction opens step flashing and counter-flashing faster than in drier climates. We use professional-grade materials from Famco and Olympia Chimney, installed with proper overlap and sealant integration to the roofing membrane. Typical flashing repair or replacement in North Bellmore costs $400-$900. We document the condition with camera photos before and after, so you see exactly what was failing and how it was corrected.

Trusted Brands We Service in North Bellmore

We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield-brands that hold up to North Bellmore’s coastal exposure. When we replace a corroded galvanized cap with a stainless DuraFlex model, or reline an old oil flue with a properly sized stainless insert, we’re specifying components designed for this environment. That local parts availability means most North Bellmore repairs don’t wait on shipping. Our technicians arrive with the right materials to complete the job in one visit, and our pricing is agreed upfront before any work begins.

Common Chimney Repair Problems We See in North Bellmore Homes

• Salt-air corrosion of galvanized chimney caps and flashing. The standard caps and flashing installed on 1950s-1960s North Bellmore homes were galvanized steel, not stainless. Salt-laden air from the Great South Bay eats through the zinc coating in 8-12 years, and once rust starts, it accelerates dramatically. We routinely find caps that look intact from the ground but are paper-thin and perforated up close.
• Spalling brick and crumbling mortar joints above the roofline. Salt-laden air followed by Long Island freeze-thaw cycling from November through March opens joints and causes brick faces to pop off. The damage is often worst on the south and west exposures, where wind-driven salt spray and afternoon sun create the harshest conditions.
• Cracked or spalled chimney crowns. The concrete crown at the top of your chimney is supposed to shed water away from the flue. When it cracks-often from freeze-thaw plus salt corrosion of underlying reinforcement-water runs behind the crown and down the flue exterior, accelerating interior water damage and rusting dampers and firebox components.
• Unlined or improperly lined flues from oil-to-gas conversions. A large share of North Bellmore homes converted from oil to gas heat over the past two decades without relining the flue. The existing 8-inch clay tile flue, sized for oil combustion, is both a code violation under Nassau County fire rules and a carbon monoxide risk with lower-temperature gas appliances. Our Level-2 camera inspection identifies this on nearly every service call.
