Call (844) 803-1545

We know Lake Grove well. Our trucks roll regularly through the neighborhoods off Hawkins Avenue, past the Smith Haven Mall corridor, and along the older streets near Lake Ronkonkoma where the post-war Capes and ranches sit shoulder to shoulder. These houses were built fast in the 1950s and 1960s, and their chimneys are aging out together. When you call (844) 803-1545, a live person answers, day or night. We’ll give you a straight answer about what you’re seeing and when we can be there.

Why Hearthstone Chimney Co. Is Lake Grove’s Preferred Chimney Repair Company

We’ve been serving Suffolk County homeowners for over 42 years, and Lake Grove has been part of our route since the village was incorporated. That longevity means something here. We’ve worked on chimneys in the original Hawkins Hill development, repointed brick on ranches near the intersection of Middle Country Road and Hawkins Avenue, and rebuilt crowns on split-levels backing up to the Nissequogue River watershed. Russell Haines founded this company in 1984 on the principle that a craftsman stands behind his work, and that hasn’t changed.

Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. The 90-Day Done Right Promise backs every repair in writing, no arguing. If it’s not right, we come back. Our technicians are background-checked, uniformed, and carry professional-grade materials from HeatShield, Gelco, and Olympia Chimney so most jobs finish in one visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice. A square deal, no surprises on the bill.

Our Chimney Repair Services in Lake Grove

Mortar Repointing

The lime-based mortar joints in Lake Grove’s 1950s-1970s brick chimneys were never meant to last seventy years. Between the village’s elevated humidity off Lake Ronkonkoma and the hard freeze-thaw cycles that hit central Suffolk every January and February, that original mortar crumbles. We grind out the deteriorated joints to proper depth and repoint with matching mortar formulated for the local climate. Done right, and we stand behind it.

Spalling Brick Repair

Spalling, the flaking and crumbling of brick faces, is epidemic in Lake Grove’s older housing stock. Moisture gets in through failed crowns or porous mortar, then winter freezes expand it from within. You’ll see it worst on chimneys that haven’t been capped or waterproofed. We remove damaged brick, source matching replacements, and rebuild the affected courses. For extensive damage, we’ll discuss whether a partial rebuild makes more sense than chasing individual bricks.

Chimney Waterproofing

Lake Grove’s position on Long Island’s glacial outwash plain means high water tables and persistent humidity that masonry absorbs like a sponge. A standard brick chimney can soak up a gallon of water in a single rainstorm. We apply vapor-permeable waterproofing agents that let the chimney breathe while shedding rain. This is preventive work that pays for itself, especially on chimneys already showing early mortar deterioration.

Flashing Repair

The step flashing where chimney meets roof is a common leak point in Lake Grove’s low-slope ranches and split-levels. Original installations from the 1960s often used galvanized steel that has corroded, or were simply caulked over by prior owners. We fabricate custom flashing and seal it properly to the roof plane. Our Chimney Cap & Crown in Lake Grove work pairs naturally with flashing repair, since a sound crown protects the flashing below from cascading water.

Trusted Brands We Service in Lake Grove

We stock professional-grade materials from HeatShield, Gelco, and Olympia Chimney on every truck serving Lake Grove, so we can handle Chimney Liner & Rebuild - Lake Grove jobs without waiting for parts. That means no waiting for parts when your chimney needs a stainless steel liner, a custom cap, or refractory sealant. We also work with Famco hardware for venting configurations. These are the brands specified by manufacturers and relied on by sweeps who plan to be in business thirty years from now. Builder-grade substitutes don’t hold up in Lake Grove’s climate, and we don’t use them.

Common Chimney Repair Problems We See in Lake Grove Homes

• Original clay tile liners cracked or shifted. The single-flue chimneys built for 1960s oil burners in ZIP 11755 weren’t designed for modern gas inserts. We regularly find tiles spalled by decades of thermal cycling, or entire sections offset by settling. A Level-2 inspection with a camera reveals what a flashlight cannot.
• Undersized or missing chimney caps. Lake Grove’s mature oaks and maples drop debris year-round, and squirrels nest with enthusiasm. An open flue invites blockages, moisture, and animal entry. A proper Gelco or Olympia Chimney cap with screening solves it permanently.
• Crown cracks from freeze-thaw. The concrete crowns on Lake Grove’s older chimneys were often poured too thin or without reinforcement. Water enters hairline cracks, freezes, and widens them into channels. We rebuild with proper slope and overhang, or apply HeatShield CrownCoat for sound crowns with minor cracking.
• Improper flue sizing from past conversions. A technician working Lake Grove regularly finds chimneys where a gas insert or pellet stove was dropped into a flue originally sized for a 1960s oil burner with no relining, a renovation shortcut common in the 1980s and 1990s. This leaves an oversized, unlined flue running a modern appliance well outside safe draft parameters, often invisible until the first camera inspection.
