We’ve been driving to Jericho for over 42 years. We know the split-levels along South Marginal Road, the Colonials near Jericho Turnpike, and the raised ranches back by the Jericho High School campus. These homes were built fast during the 1950s and 1960s Long Island boom, and their chimneys are now 60-70 years old - well past the typical service life of original mortar and brick. That age matters. So does the fact that most were converted from oil to gas heat without relining the oversized flues, a pattern we see constantly in ZIP codes 11753 and 11853. We don’t guess at what’s wrong. Our Level-2 camera inspection shows you exactly what we’re seeing, and our 90-Day Done Right Promise means if it’s not right, we come back. In writing, no arguing.

Our Chimney Repair Services in Jericho

Mortar Repointing

Jericho’s original masonry chimneys are running out of mortar. The freeze-thaw cycles on Long Island cross 32°F dozens of times each winter, and each cycle forces water deeper into joints that were never meant to last 70 years. We grind out deteriorated mortar to proper depth and repoint with custom-matched mortar that respects the original brick. On a recent job near the intersection of Jericho Turnpike and North Marginal Road, we repointed a 1964 chimney where the original lime mortar had turned to sand. The homeowner watched our photos, approved the scope, and we finished in one day. Repointing in Jericho typically runs $1,200-$2,400 for a standard chimney.

Spalling Brick Repair

Spalling - when brick faces flake off from freeze-thaw damage - is epidemic in Jericho because of the salt-laden air carried from Long Island Sound, roughly 10-12 miles away. That salt accelerates the deterioration of exposed masonry, especially on chimneys above the roofline where wind hits hardest. We replace spalled bricks with matching units and address the underlying moisture source, whether it’s a failed crown, deteriorated flashing, or an unlined flue dumping condensation into the stack. If your chimney needs a Chimney Liner & Rebuild - Jericho, we’ll identify that during inspection. Spalling repair in Jericho ranges from $800 for localized replacement to $2,800 for extensive rebuilding of multiple courses.

Chimney Waterproofing

Waterproofing a Jericho chimney requires understanding that the water isn’t just coming from rain - it’s coming from inside. Oversized oil-to-gas flues create chronic condensation that saturates the interior masonry, then pushes efflorescence and freeze damage to the exterior. We apply professional-grade breathable sealants from Copperfield that block liquid water while letting vapor escape, and we always inspect the flue lining first. For Chimney Cleaning & Sweep in Jericho, we include this flue check as standard. Waterproofing without fixing the flue is painting over rot. A proper waterproofing job in Jericho runs $650-$1,400 depending on chimney size and accessibility.

Flashing Repair

The step flashing where Jericho’s chimneys meet their roofs was often installed with galvanized steel in the 1950s and 1960s, and that metal is now rusting through. We remove failed flashing, inspect the underlying decking for rot (common in homes with decades of slow leaks), and install new copper or stainless step flashing with proper counterflashing integration. On Jericho’s split-levels with low-slope roof sections, this repair is particularly critical because water pools rather than runs off. Flashing repair in Jericho typically costs $750-$1,800.

Chimney Rebuilding

Some Jericho chimneys are too far gone for spot repair. When the interior wythes are compromised, the liner is failing, and multiple courses show spalling or displacement, we rebuild from the roofline up or from the ground up depending on structural assessment. We recently rebuilt a chimney on a Colonial near the Jericho Public Library where two flues - one retired oil flue, one active fireplace flue - had both deteriorated past safe use. The homeowner had assumed the unused flue was harmless. It wasn’t. Rebuilding in Jericho ranges from $3,500 for partial rebuilds to $8,500+ for full stack replacement with new liner installation.

Tuckpointing

For Jericho homeowners with historic or decorative masonry, tuckpointing restores the fine-line aesthetic of original joints while sealing out moisture. We match joint profiles and mortar color to maintain the architectural character these mid-century homes deserve. Tuckpointing runs $1,500-$3,200 in Jericho depending on detail level and scaffold requirements.

Trusted Brands We Service in Jericho

We don’t use builder-grade substitutes. Our Chimney Repair trucks carry professional-grade materials from DuraFlex, HeatShield, Gelco, and Famco - brands that hold up to Jericho’s salt air and freeze-thaw punishment. DuraFlex liners handle the corrosive condensation from gas conversions better than standard aluminum. HeatShield cerfractory flue sealant restores cracked clay liners without full replacement when the damage is localized. We stock common sizes and fittings locally, so most Jericho repairs don’t wait on parts. If your chimney needs a specific component, we source it from Olympia Chimney or Copperfield supply houses with next-day availability to Long Island. The right material for the job, installed correctly, backed by our 90-Day Done Right Promise. That’s the deal.

Common Chimney Repair Problems We See in Jericho Homes

• Neglected oversized flues from oil-to-gas conversions. Over 70% of Jericho’s mid-century homes were converted from oil to gas heat without relining the oversized flues, leaving dormant chimneys that silently deteriorate from condensation and efflorescence - a hazard unique to neighborhoods built during the 1950s-60s Long Island boom. Homeowners assume a chimney they don’t use can’t cause problems. The opposite is true.
• Salt-accelerated spalling on exposed masonry. Jericho sits close enough to Long Island Sound that prevailing winds carry measurable salt content, which gradually degrades mortar joints and chimney crowns. Combined with repeated freeze-thaw cycles each winter, aging brick chimneys experience accelerated deterioration that more inland neighbors don’t see at the same rate.
• Dual-flue neglect. It’s common for Jericho’s post-WWII homes to have two separate flues - one that originally served the oil boiler and a second for a wood-burning fireplace. Homeowners often service the active flue and forget the retired one, or assume both are fine because the fireplace “works fine.” Moisture damage doesn’t care whether you’re paying attention.
• Failed chimney crowns from original construction. The concrete crowns poured in the 1950s and 1960s were rarely reinforced or properly sloped for drainage. After 60+ years of thermal cycling, they’re cracked, porous, and funneling water directly into the chimney stack. A crown that looks “just a little cracked” from the ground is often shattered at the top.
