We’ve been working in Hempstead for over 42 years. We know the narrow side yards off Fulton Avenue, the tight parking along Peninsula Boulevard, and the two-family brick homes packed into the 11550 ZIP code where access is cramped and chimneys have been ignored for decades. Our trucks carry the materials to fix your chimney right then, not after a second trip.

Our response time to Hempstead averages same-day or next-day. We understand that a cracked crown or failed flashing doesn’t wait for convenient weather, especially when spring nor’easters are rolling in off Hempstead Bay.

Frank Calucci has led this company since 1984. That’s 42 years of showing up when we say we will, standing behind our work with the 90-Day Done Right Promise in writing, and treating Hempstead homes with the care we’d want for our own. We’ve worked on chimneys near Hofstra University, along the older blocks of the village core, and throughout the dense rental corridors where deferred maintenance is the rule, not the exception.

Our technicians are background-checked and uniformed. Most repairs finish in one visit. The price we quote is the price on the invoice.

Our Chimney Repair Services in Hempstead

Mortar Repointing

Hempstead’s coastal position means repeated freeze-thaw cycles every winter, with marine humidity from Hempstead Bay and the South Shore eating away at mortar joints on exposed chimney stacks faster than you’ll see in inland Long Island towns. In the 11550 ZIP code, we regularly find original mortar from the 1940s and 1950s turned to powder. We grind out the failed joints to proper depth and repoint with color-matched, professional-grade mortar rated for Nassau County’s wet winters. Done right, and we stand behind it.

Spalling Brick Repair

Spalling, the face of the brick popping off, is epidemic in Hempstead’s postwar housing stock. The root cause is usually moisture trapped behind the brick face, and in Hempstead that moisture often comes from two sources: exterior saturation from coastal humidity and interior condensation from oversized flues venting cool gas exhaust. We cut out spalled bricks, replace with matching units, and address the moisture source so the repair lasts. We recently repaired a chimney on a two-family home on Fulton Avenue in the village core where the landlord had swapped an old oil boiler for a 90%-efficiency gas unit without relining. We relined the oversized 8″x13″ terra-cotta flue with a DuraFlex stainless steel liner and sealed the crown, stopping the persistent white efflorescence that had been bleeding through the brick.

Chimney Waterproofing

Hempstead’s older masonry was never designed to repel the volume of wind-driven rain that hits the South Shore. We apply vapor-permeable waterproofing agents that let the chimney breathe while blocking water entry. This is especially critical on Cape Cod homes with shallow-pitched roofs where the chimney stack takes the full force of weather with little protection. One application typically protects for 10 years.

Flashing Repair

Spring nor’easters regularly dislodge chimney caps and compromise flashings on the shallow-pitched roofs common to Hempstead’s Cape Cods. We replace damaged step flashing and counterflashing with copper or professional-grade aluminum, sealed with high-temperature compounds. On homes near Hempstead Bay where salt air accelerates corrosion, we specify materials that hold up to the environment.

Chimney Rebuilding

When deterioration has gone too far for spot repair, we rebuild. In Hempstead’s high-rental-turnover market, we’ve seen chimneys that haven’t been touched since the Truman administration. We rebuild from the roofline up, matching existing brick and installing proper crowns, caps, and liners so the new work outlasts the original. Every rebuild includes our 90-Day Done Right Promise in writing.

Tuckpointing

For chimneys where the mortar is failing but the brick is sound, tuckpointing restores structural integrity without the cost of rebuilding. We work carefully on Hempstead’s older homes where the original craftsmanship deserves respect, not a sledgehammer.

Trusted Brands We Service in Hempstead

We stock professional-grade materials from Gelco, Olympia Chimney, and Famco, among others, so Hempstead repairs don’t wait on parts orders. A typical flashing job or cap replacement on a home near Peninsula Boulevard gets same-day completion because our trucks carry the inventory. For liner installations, we specify DuraFlex stainless steel, the standard for converting Hempstead’s oversized terra-cotta flues to safe, efficient gas venting. No builder-grade substitutes. The materials matter as much as the labor.

Common Chimney Repair Problems We See in Hempstead Homes

• Cracked crowns from decades of neglect. In Hempstead’s dense rental market, chimneys often go uninspected for 20 or 30 years. The concrete crown cracks, water penetrates, and freeze-thaw cycling destroys the top courses of brick.
• The “gas-in-an-oil-flue” mismatch. When landlords swapped oil boilers for 90%-efficiency gas units without relining, the oversized terra-cotta flue runs cold. White sulfurous efflorescence bleeds through exterior brick, a tell-tale sign visible on dozens of properties near the village core.
• Failed mortar joints accelerated by coastal humidity. Nassau County’s marine environment drives mortar erosion faster than inland communities. We see joints recessed half an inch or more on chimneys facing Hempstead Bay.
• Dislodged caps and compromised flashings after nor’easters. The shallow-pitched roofs on Hempstead’s Cape Cods offer little wind protection. Spring storms lift caps and peel back flashing, opening direct paths for water.
