Our Chimney Liner & Rebuild Services in North Bellmore

Stainless Steel Liner Installation

Stainless steel liners are what most North Bellmore homes need after an oil-to-gas conversion. The original 8-inch clay flue in your 1950s or 1960s chimney was sized for an oil-fired boiler running at 500°F-plus. Today’s gas appliances exhaust cooler, wetter flue gases that condense on those old tiles, causing spalling and mortar failure. We install insulated stainless steel liners from DuraFlex and Olympia Chimney, properly sized to the appliance and venting configuration. A typical stainless steel liner installation in North Bellmore runs $1,800-$3,200 depending on flue height, diameter, and whether the existing clay needs extraction.

Flexible Liner Solutions

Some North Bellmore chimneys have offsets or bends that make rigid stainless steel impossible to feed. For these, we use flexible liner systems that navigate around offsets while maintaining proper draft. Flexible liners are especially common in the older Cape Cods near the Wantagh Parkway corridor, where chimneys were often built with slight bends to avoid structural elements. Expect $2,000-$3,800 for a flexible liner installation with proper insulation and top-sealing.

Liner Replacement

When an existing stainless or clay liner has failed - cracked tiles, holes from corrosion, or collapse from freeze-thaw damage - full liner replacement is the only safe option. In North Bellmore, we see this most often in homes where a previous liner installation used substandard materials or where the original clay tiles have simply reached end of life after 60-plus years of salt air and thermal cycling. Liner replacement in North Bellmore typically costs $2,200-$4,500. We extract the failed material, inspect the surrounding masonry with our camera, and install a new insulated system from Gelco or HeatShield.

Partial Chimney Rebuild

Not every deteriorated chimney needs to come down to the roofline. A partial rebuild addresses the section above the roof - where North Bellmore chimneys take the worst beating from salt-laden bay air and wind-driven rain - while preserving sound masonry below. We had a call off Bellmore Avenue in the North Bellmore area where a homeowner’s 1950s Cape Cod had been converted from oil to gas back in the 1990s, but the original 8-inch clay tile flue was never relined. Our tech ran a Level 2 inspection with a camera and found the old tiles spalling and the mortar joints crumbling - clear freeze-thaw damage from years of salt air off the nearby South Shore bays. We showed the homeowner the footage, then installed an insulated stainless steel liner sized for the gas appliance, and replaced the cracked crown and cap while we were up there. Partial rebuilds in North Bellmore run $3,500-$6,500 depending on height and brick matching.

Common Chimney Liner & Rebuild Problems We See in North Bellmore Homes

• Unlined or clay-tile flues behind a gas conversion. The 1990s and 2000s oil-to-gas conversions across North Bellmore often skipped the relining step. The existing 8-inch clay flue is too large for gas exhaust, causing condensation that spalls tiles and rots mortar. We find this on roughly half our service calls here.
• Salt-laden air eroding mortar and brick faces above the roofline. North Bellmore sits 2-3 miles from the Great South Bay. That salt air eats mortar joints and causes brick face spalling years before you’d see it in inland Nassau County communities like Uniondale or Roosevelt. The damage starts invisible and accelerates fast.
• Freeze-thaw cycling cracking crowns and letting water into the stack. November through March brings repeated hard freezes and thaws to Long Island. Water gets into salt-weakened joints, expands when it freezes, and cracks the crown. Once the crown fails, water runs down the flue, damaging the smoke chamber and firebox.
• Deteriorated parging and smoke chamber walls in 60-plus-year-old chimneys. The original parging in North Bellmore’s post-war chimneys was often thin and poorly bonded. After decades of thermal cycling and moisture, it flakes away, exposing rough masonry that catches creosote and restricts draft.
