Dispatch and scheduling are coordinated from our New York City office, while our local crews handle service across Merrick and the surrounding South Shore. When a Merrick homeowner calls about a leaking chimney after a nor’easter, we know the housing stock we’re dealing with before the truck leaves: 1950s-1970s split-levels and colonials, original clay liners, and decades of salt exposure on the crowns and caps.

Chimney Liner Installation in Merrick

Chimney Liner Installation in Merrick is one of the most common repairs we perform on the original clay flues that came with mid-century split-levels and colonials. A liner is the inner channel that carries smoke and exhaust safely out of the house. When the original clay liner cracks, spalls, or deteriorates, exhaust gases can leak into the home, and carbon monoxide becomes a real hazard. In Merrick, the problem is compounded by oil-fired heating: acidic oil exhaust has been eating away at clay liners since these houses were built. A standard stainless steel liner installation in Merrick runs $1,800 to $3,200 depending on flue length and access.

When a Merrick Homeowner Needs a New Liner

You need a liner when a Level 2 inspection shows cracks, gaps, or missing sections in the original clay. You also need one if you’re switching from an old oil burner to a newer, higher-efficiency unit: the new exhaust temperatures and chemistry can wreck an old clay liner quickly. We specify stainless steel liners from DuraFlex because they’re rated for oil exhaust and hold up to coastal humidity better than aluminum alternatives.

What Liner Installation Involves

Our tech measures the flue, runs a stainless steel liner down the existing chimney, and insulates or connects it according to the appliance and local code. The job usually takes a single day. We handle all cleanup, and you get a written price before we start, plus the 365-Day Done Right Promise in writing when we finish.

Chimney Flashing Repair in Merrick

Chimney Flashing Repair in Merrick deals with the metal seal where the chimney meets the roofline, a spot that takes a beating from wind-driven salt spray off the Atlantic. Flashing is the thin metal barrier that keeps rain from running down the chimney and into the attic. When flashing rusts through, loosens, or separates from the brick, water gets into the roof deck and insulation. In Merrick, flashing replacement or repair typically runs $350 to $1,100 depending on the extent of damage and the roof pitch.

Why Flashing Fails Faster Near the Coast

Galvanized flashing has a limited life in salt air; we regularly see rust-through within 10 to 12 years on Merrick homes. Copper flashing lasts far longer, and we install Copperfield copper flashing for homeowners who want a repair that won’t need attention for decades. The decision comes down to what the homeowner wants to spend now versus what they’ll spend again sooner than expected.

Repair Options We Recommend

Sometimes a section of flashing can be resealed with high-grade sealant and new fasteners. More often, the metal itself is too far gone and needs replacement. We always check the mortar joints directly below the flashing line, because salt-driven erosion there is usually what opened the gap in the first place. A flashing repair that ignores the masonry won’t hold.

Trusted Brands We Service in Merrick

Flint Chimney Co Hempstead works with professional-grade chimney materials from brands including Olympia Chimney, Famco, Copperfield, and DuraFlex. We specify by what the job needs, not by what carries the highest margin. That means stainless steel caps and liners rated for coastal conditions, copper flashing that holds up to salt spray, and components we can stand behind for a full year under the 365-Day Done Right Promise. We keep common repair parts stocked locally for Merrick calls, which means less waiting when you need a cap replaced or a liner section addressed. If a manufacturer’s defect surfaces within the guarantee period, we handle the replacement and the return visit.

Common Chimney Repair Problems We See in Merrick Homes

• Rusted galvanized caps. Salt-laden air from the water chews through galvanized steel in 5 to 7 years. Once the cap fails, rain pours down the flue, mixes with creosote, and forms acidic sludge that eats the liner from the inside.
• Cracked clay flue liners from oil heat. The 1950s-70s chimneys around Merrick were built for a different era. Decades of acidic oil exhaust have left original clay liners spalling and cracked, a condition our Level 2 inspections catch regularly in Freeport, Wantagh, and across the Merrick area.
• Eroding mortar joints and spalling brick. Wind-driven salt spray works into the mortar, freezes and expands in winter, and pops the brick face off. We recommend mortar repointing and tuckpointing before the damage reaches structural level.
• Water damage at the flashing line. Rusted or separated flashing lets water into the attic, which shows up as ceiling stains around the chimney chase. We fix the flashing and address the masonry underneath so the repair holds.
