Why Hearthstone Chimney Co. Is Jericho’s Preferred Chimney Repair Company

We’ve worked on enough Jericho chimneys to know the patterns. The raised ranches near the Syosset border with their double flues. The colonials off Jericho Turnpike where nor’easters drive rain straight into aging crowns. The split-levels where a gas-log set installed in the 1990s vents into clay tile that was never meant to handle condensing exhaust.

Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your liner can wait, we’ll say so. If it can’t, we’ll show you exactly why.

The 90-Day Done Right Promise governs every repair we make in Jericho: Krafted right, Every time, Your home first, Standing behind it. In writing. No arguing. If it’s not right, we come back.

Calls are answered by a live person, every hour of every day. Our technicians are background-checked, uniformed, and carry professional-grade materials from brands like DuraFlex, HeatShield, and Gelco. Most repairs are completed in a single visit, with no-hassle upfront pricing - the number on the estimate is the number on the invoice.

Our Chimney Repair Services in Jericho

Chimney Rebuilding

Some Jericho chimneys have simply reached the end of their service life. The post-WWII tract homes here - colonials, split-levels, raised ranches - were built with masonry chimneys under older codes, and after 50-70 years of Nassau County freeze-thaw cycles, the structure itself can fail. We rebuild from the roofline up or perform partial rebuilds of damaged courses, matching existing brick where possible and using Olympia Chimney components for crowns and caps. Every rebuild in Jericho requires attention to the Town of Oyster Bay permit process, which we handle directly.

Flashing Repair

Flashing is the metal seam where your chimney meets the roof, and it’s the single most common leak point we find in Jericho homes. Winter temperature swings across Long Island open these seams slowly, then nor’easter rain finds the gap. By October, a homeowner lights the first fire and notices water staining around the firebox. We repair or replace step flashing and counterflashing using professional-grade materials, and we document the condition of the surrounding roof deck so you know whether the problem stops at the chimney or extends further.

Chimney Waterproofing

Jericho’s wind exposure is no joke. Chimneys on these 1950s-1970s homes often lack adequate crown overhang or proper cap protection, and wind-blown rain soaks into porous brick year after year. We apply vapor-permeable waterproofing agents that let the masonry breathe while blocking water entry. This isn’t a cosmetic treatment. For a chimney with sound mortar but aging brick, waterproofing can add a decade of service life before repointing becomes necessary.

Mortar Repointing & Tuckpointing

When mortar joints erode - common on Jericho chimneys after decades of freeze-thaw - water enters the wall cavity and the cycle accelerates. We grind out failed joints to proper depth and repoint with color-matched mortar, restoring structural integrity and appearance. Tuckpointing for cosmetic refinement is available where the brick itself remains sound.

Spalling Brick Repair

Spalling - the flaking and crumbling of brick faces - is what happens when water trapped in the masonry freezes and expands. Jericho’s older chimneys show this pattern frequently on the north and west exposures, where winter wind and rain hit hardest. We replace spalled brick units and address the water source, whether it’s failed flashing, a cracked crown, or missing cap.

Trusted Brands We Service in Jericho

We don’t use builder-grade substitutes. Our Jericho repairs specify professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - brands that stand up to Nassau County’s climate and meet the expectations of this market. We stock common liner diameters and flashing configurations locally, so most Jericho repairs don’t wait on parts. When a DuraFlex stainless liner is the right solution for a gas retrofit in a 1960s colonial, we size it precisely to the appliance and pull the required Town of Oyster Bay permit before installation begins.

Common Chimney Repair Problems We See in Jericho Homes

• Gas insert retrofits venting into original 1950s clay tile flue liners not rated for gas exhaust. The moisture-laden exhaust condenses in the cool clay, accelerating spalling and cracking that goes completely unnoticed until a Level 2 inspection reveals the damage. This is the most common hidden problem in Jericho’s tract homes.
• Nor’easter wind-driven rain entering uncapped or short chimney crowns on older masonry chimneys. Jericho’s exposure to prevailing westerlies means rain hits these chimneys harder than more sheltered inland areas. Water enters through the crown, tracks down the flue, and damages the firebox, damper, and surrounding framing.
• Freeze-thaw cycling across Nassau County winters cracking the chimney crown and opening flashing seams. Temperatures in this region routinely oscillate across the freezing point in a single week. Water enters micro-cracks, expands overnight, and repeats until the crown fails or flashing lifts. We’ve repaired chimneys in Jericho where this cycle destroyed a crown in under five years.
• Third-degree creosote glazing in heavily used wood-burning fireplaces after summer disuse. Jericho homeowners who burn regularly from October through March often discover hardened, glazed creosote that a standard brush won’t remove. This requires chemical treatment or rotary cleaning, and it frequently reveals underlying liner damage that wasn’t visible during the previous season’s inspection.
