We’ve been working on Melville chimneys for decades. The hamlet’s postwar housing stock, built during the Town of Huntington’s 1960s-1980s suburban expansion, presents repair challenges that differ from older North Shore villages or newer developments farther east. Those colonials and expanded ranches along Route 110, in the West Hills area, and near the Melville Marriott often have original clay tile liners now hitting 40 to 60 years of service, plus the accumulated effects of Long Island’s salt-laden air and repeated freeze-thaw cycles. We know what to look for because we’ve seen it hundreds of times.

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

Melville homeowners tend to stay put. They’ve raised families in these houses, watched the Long Island Expressway widen, and remember when the area was still considered “out east.” That kind of rootedness deserves a repair company that plans to stick around too. We’ve served local communities for over 42 years, and we’re built to be here in thirty more.

Our reputation here rests on documentation, not promises. Every inspection ends with photos you can see and a plain-English verdict. If we recommend relining, you’ll see the acid-pitted clay or cracked tile on screen before we quote a dollar. Nothing gets sold on speculation. Our 90-Day Done Right Promise backs every job in writing with no arguing - if it’s not right, we come back.

Calls are answered by a live person, 24 hours a day, 7 days a week. No voicemail, no callback queue. Our background-checked, uniformed technicians carry professional-grade materials from DuraFlex, HeatShield, and Olympia Chimney on their trucks, so most Melville repairs are completed in a single visit without waiting for parts. The number on the estimate is the number on the invoice.

Our Chimney Repair Services in Melville

Chimney Relining

This is the repair we find ourselves recommending most often in Melville, and it’s almost always a surprise to the homeowner. Many homes built during the 1960s-1980s have oversized clay flue tiles originally sized and glazed for oil combustion. After the oil-to-gas conversions that swept through Suffolk County in the 1990s and 2000s, those same flues now channel cooler, wetter gas exhaust. The result is chronic condensation that etches the clay from within, creating hidden cracks and pitting that a basic visual inspection misses entirely.

During a Level 2 inspection on a 1970s colonial in the West Hills section of Melville, our tech used a camera to find acid-pitted clay flue tiles behind seemingly intact mortar in a chimney that had been converted from oil to gas. We installed a HeatShield stainless steel liner and repointed the crown, restoring safe draft for the homeowner’s gas furnace and fireplace. That kind of hidden damage is exactly why we insist on camera documentation. Relining with a properly sized stainless steel or DuraFlex liner typically runs $1,800-$3,200 in Melville, depending on flue count and height.

Chimney Waterproofing

Melville sits roughly five miles south of Long Island Sound, close enough for salt-laden air to accelerate mortar joint erosion and brick spalling at a rate faster than truly inland suburbs. Nor’easters drive wind-blown rain directly into chimney crowns and exposed joints, and Suffolk County’s freeze-thaw cycles do the rest. Waterproofing isn’t cosmetic here; it’s structural preservation.

We apply professional-grade, vapor-permeable sealants that allow the masonry to breathe while blocking liquid water. On homes near the Old Country Road corridor or in more exposed sections of the hamlet, we often pair waterproofing with crown resurfacing using HeatShield materials. A typical Melville waterproofing treatment runs $800-$1,400 for a standard single-flue chimney, with reapplication recommended every 5-7 years depending on exposure.

Mortar Repointing

The mortar between your bricks is sacrificial - it’s designed to deteriorate before the brick does. In Melville, that deterioration happens faster than the original builders anticipated. Salt air, thermal cycling, and the settling common in 40-to-60-year-old foundations all conspire to open joints and create pathways for water.

We grind out failed mortar to proper depth and repoint with color-matched, professional-grade mortar formulated for Long Island’s climate. Tuckpointing on a standard Melville colonial typically runs $650-$1,500 for localized repair, or $2,000-$3,500 for full chimney repointing. We don’t repoint what doesn’t need it. If the damage is superficial, we’ll say so.

Spalling Brick Repair & Chimney Rebuilding

When spalling advances past surface flaking into structural compromise, partial or full rebuilding becomes necessary. Melville’s freeze-thaw damage often concentrates on the south and west faces of chimneys, where sun exposure followed by rapid temperature drops creates the most stress. We rebuild with matching brick and proper weatherproofing, and we document the cause so you understand why it happened. Rebuilding ranges from $3,000 for partial reconstruction to $6,500 or more for full chimney teardown and rebuild on larger homes.

Flashing Repair & Prefabricated Chase Restoration

Even newer Melville homes with factory-built fireplaces suffer chimney problems. Prefabricated chase covers rust through. Flashing separates from the roofline after years of thermal movement. We repair and replace these components with proper materials - Gelco caps, custom flashing, chase covers fabricated to spec - not the builder-grade originals that failed in the first place.

Trusted Brands We Service in Melville

We stock our Melville service trucks with professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - brands we’ve specified for decades because they hold up to Long Island’s coastal climate. No builder-grade substitutes, no waiting a week for parts to ship. When we find a failed DuraFlex liner or a cracked HeatShield crown during your inspection, the replacement is typically installed that same visit. That matters in Melville, where heating season waits for no one and a second trip costs you another day of scheduling.

Common Chimney Repair Problems We See in Melville Homes

• Hidden liner failure after oil-to-gas conversion. The oversized clay flue tiles common in 1960s-1980s Melville homes were never meant for gas exhaust. Condensation etches the glaze, cracks the tile, and destroys draft efficiency - all out of sight until a camera inspection reveals it.
• Salt-accelerated mortar erosion on south and west exposures. Long Island Sound’s salt-laden air reaches Melville even at five miles inland, speeding up the chemical breakdown of mortar joints and leaving brick faces vulnerable to spalling.
• Crown cracking from nor’easter-driven rain and freeze-thaw. Wind-blown rain saturates the concrete crown, winter freezes it solid, and spring thaw leaves cracks that funnel water straight into the flue. We see this pattern repeatedly on homes near the more exposed stretches of Route 110.
• Prefabricated chase deterioration on newer homes. Factory-built fireplaces in 1980s-and-later construction use galvanized chase covers that rust through in 10-15 years. Homeowners assume a newer chimney is fine; the rust stains on their siding tell a different story.
