We’ve been working on Franklin Square chimneys since 1984. We know the post-war Cape Cods along Hempstead Turnpike, the ranches tucked behind the Southern State Parkway, and the brick chimneys that have been baking, freezing, and soaking for 70-plus years. Franklin Square’s housing stock is remarkably consistent - and so are the problems we find. Oil-to-gas conversions, freeze-thaw damage, and liner deterioration from oversized flues: we’ve seen it all, and we know what to look for before it becomes dangerous.

Our Chimney Repair Services in Franklin Square

Chimney Rebuilding

Some Franklin Square chimneys are simply too far gone for spot repairs. The post-WWII brick was decent quality, but 70 years of Nassau County freeze-thaw cycles will defeat anything. When the structural integrity is compromised - multiple courses of spalled brick, shifted flue tiles, or a leaning stack - we rebuild. We match existing brick and mortar color where possible, and we always install a proper crown with positive drainage. A rebuilt chimney in Franklin Square typically runs $3,200-$6,800 depending on height and access. We use professional-grade materials from Copperfield and Olympia Chimney - no builder-grade substitutes.

Tuckpointing & Mortar Repointing

Repointing is our most common Franklin Square repair. The original mortar in these 1940s-1960s chimneys was lime-based and porous - good for breathability, but it erodes. Franklin Square’s inland position means no salt-air buffer and no significant wind break, so mortar joints face brutal expansion-contraction stress. We grind out failed joints to proper depth and repoint with color-matched, properly cured mortar. A typical repointing job on a Franklin Square Cape Cod chimney runs $850-$1,800. Done right, it buys you 25-30 years.

Spalling Brick Repair

Spalling - brick faces popping off from freeze-thaw damage - is epidemic on north-facing Franklin Square chimneys that never fully dry. We replace spalled bricks with matching units and address the water intrusion source, usually failed crown or flashing. On Field Avenue, a homeowner smelled smoke after converting their oil burner to gas. We found the clay-tile liner cracked from freeze-thaw stress and condensation damage. We installed a DuraFlex stainless steel liner to match the new gas appliance and tuckpointed the crown, securing the chimney for another 30 years. Spalling repair in Franklin Square typically runs $1,200-$2,800.

Flashing Repair

Franklin Square’s modest Cape Cods and ranches often have simple roof-to-chimney intersections, but the flashing was frequently installed as an afterthought in the original construction. We see step flashing rusted through, counter-flashing separated from mortar, and caulk jobs that sealed in water instead of keeping it out. Our flashing repair uses professional-grade materials from Gelco and Famco, properly integrated with the roofing system. Typical Franklin Square flashing repair: $650-$1,400.

Chimney Waterproofing

Water is the enemy of every Franklin Square chimney. We apply vapor-permeable sealers that let the brick breathe while repelling liquid water - critical in our climate where trapped moisture freezes and expands. Waterproofing a standard Franklin Square chimney runs $450-$950 and should be refreshed every 7-10 years.

Trusted Brands We Service in Franklin Square

We don’t guess about materials. For Franklin Square repairs, we stock and install professional-grade products from DuraFlex, HeatShield, Gelco, and Copperfield - brands that have proven themselves in our climate. DuraFlex stainless steel liners handle the condensation from gas conversions without corroding. HeatShield cerfractory flue sealant restores cracked clay tile liners when full relining isn’t necessary. We keep common sizes in stock, so Franklin Square customers aren’t waiting two weeks for a part. The number on our estimate is the number on our invoice.

Common Chimney Repair Problems We See in Franklin Square Homes

• Condensation from oversized oil-to-gas flues eating through 70-year-old clay tiles. Franklin Square has one of the highest heating-oil conversion rates in Nassau County. The original flues were sized for oil burners drafting at higher temperatures. Natural gas runs cooler and wetter, and that moisture condenses in the oversized flue, saturating and cracking clay tiles. This creates real carbon monoxide risk. Every chimney cleaning we perform in Franklin Square includes a liner assessment for conversion damage.
• Second-generation liner patches from 1980s conversions now failing. When oil-to-gas conversions first spiked in the 1980s-90s, many Franklin Square chimneys got quick patch jobs - stainless steel sleeves poorly sized, or poured-in-place liners that didn’t bond. Those patches are now 30-40 years old and failing. We regularly find hidden cracks beneath what owners assumed was a “fixed” chimney. The only way to know is a Level-2 camera inspection with photos you can see.
• Freeze-thaw spalling on north-facing chimneys. Franklin Square’s inland position exposes chimneys to raw winter wind and full freeze-thaw cycling. Chimneys on the north side of a house never get sun to dry them. Brick faces pop off. Mortar joints crumble. We’ve replaced entire courses on chimneys that looked fine from the ground.
• Crown cracks letting water straight to the flue. The concrete crown on top of your chimney is supposed to shed water past the brick. In Franklin Square, crowns were often poured too thin or without proper reinforcement. A cracked crown funnels water directly into the chimney structure. We rebuild crowns with proper slope, overhang, and expansion joints - or we install Gelco pre-formed crowns where appropriate.
