Lake Grove customers aren’t looking for the cheapest sweep — they’re looking for someone who understands why their 1968 split-level on Mulford Lane has two flues and only one cap.

Our Fireplace Services in Lake Grove
Gas Fireplace Service
Gas fireplaces in Lake Grove’s 1950s–1970s housing stock often get installed in original masonry chimneys never designed for them. The cooler, moisture-laden exhaust of modern high-efficiency gas units condenses inside oversized flues built for oil burners, corroding liners and staining firebox walls. We inspect the burner assembly, test gas pressure, check for proper venting, and verify your flue size matches the appliance — a mismatch we find constantly in Lake Grove’s converted split-levels.
Wood Burning Fireplace
Weekly winter fires in a Lake Grove Cape Cod or ranch mean annual cleaning is non-negotiable. Central Suffolk’s freeze-thaw cycles fracture clay tile liners, and wind-driven rain from nor’easters soaks unprotected flues, accelerating spalling and mortar joint failure. We sweep to NFPA 211 standards, inspect with a chimney camera, and document liner condition — especially critical on north-facing chimneys where moss growth signals deeper moisture infiltration.
Fireplace Insert Installation
A properly sized insert transforms an inefficient open fireplace into a heat source you can actually use. In Lake Grove’s older homes, we frequently find the original firebox too damaged for safe open burning but structurally sound enough for a listed insert with a stainless steel liner. We size the unit to your existing opening, run a DuraFlex or Olympia Chimney liner from insert to cap, and handle all combustion-air requirements — critical in tight, postwar construction where make-up air is limited.
Damper Repair
A stuck or rusted damper wastes heat and invites downdrafts. In Lake Grove’s coastal climate, cast-iron throat dampers corrode faster than inland, and the pivot pins seize after decades of salt-air exposure. We repair or replace with stainless steel components, or upgrade to a top-sealing damper that doubles as a chimney cap — a smart move given how nor’easters drive rain straight down open flues here.
Fireplace Conversion
This is where Lake Grove’s housing history creates specialized work. Converting a wood fireplace to gas — or adapting an old oil-heating chimney for a new gas fireplace — requires resizing the flue, verifying liner integrity, and often abandoning or properly sealing a second furnace flue. We recently serviced a 1962 split-level on Mulford Lane where the homeowner had converted to natural gas, leaving the old oil flue uncapped. During a cleaning, we found the unused flue acting as a cold-air chimney, pulling soot and moisture into the adjacent fireplace flue and coating the liner with corrosive creosote. We installed a DuraFlex relining system in the active flue and sealed the furnace flue with a stainless steel cap to prevent future issues.
Firebox Repair
Cracked firebrick, deteriorated refractory panels, or heat-compromised mortar joints turn a cozy fire into a house fire risk. In Lake Grove’s 50-to-70-year-old masonry, we’ve replaced entire firebox floors where decades of thermal cycling shattered the original brick. We rebuild with HeatShield refractory mortar or new firebrick, matched to your unit’s specifications, and always inspect the surrounding structure for hidden water damage.
Our Fireplace Services team handles everything from routine maintenance to complex conversions — Gary Murphy personally oversees every Lake Grove project.
Trusted Brands We Service in Lake Grove
We don’t guess at parts. Our truck stocks DuraFlex stainless liners, HeatShield refractory systems, and Copperfield chimney caps — materials specified by chimney professionals, not stocked at big-box retailers. For Lake Grove customers, that means faster turnaround: when Gary finds a failed liner during your annual sweep, he can often schedule the relining within the same week instead of ordering parts and leaving you with an unsafe fireplace. We also work with Famco and Gelco components when the job calls for specialized venting solutions.
Common Fireplace Services Problems We See in Lake Grove Homes
- Abandoned dual-flue oil furnaces left open after gas conversion create dangerous cross-draft and creosote buildup inside the active fireplace flue. Many of Lake Grove’s 1960s split-levels and ranches were built with dual-flue chimneys — one serving the fireplace, one venting the oil burner — and when owners convert to gas or high-efficiency equipment, the old furnace flue is frequently left abandoned or improperly transitioned, creating a dangerous draft and creosote-deposit scenario that technicians here uncover on a regular basis.
- Original clay tile liners from the 1955–1975 era crack and spall under repeated freeze-thaw cycles, especially on north-facing chimneys where moisture wicks and moss growth signals deep damage. Central Suffolk County experiences repeated hard freeze-thaw cycles each winter, which systematically fracture aging mortar joints and clay tile liners in Lake Grove’s older chimneys.
- Wind-driven rain from nor’easters enters crowned open flues absent proper caps, accelerating interior liner degradation and efflorescence on brickwork. The moderately humid Long Island climate promotes moss growth and efflorescence on north-facing chimney masonry, a reliable surface indicator of deeper moisture infiltration.
- Oversized masonry flues mismatched to modern gas appliances cause acidic condensation that destroys liners from the inside out. As Lake Grove homeowners convert aging oil systems to natural gas, oversized masonry flues built for oil burners must be relined to safely handle the cooler, more moisture-laden exhaust of modern high-efficiency equipment — making relining assessments a routine part of every cleaning call here.

FAQs — Fireplace Services in Lake Grove
The abandoned furnace flue can become a cold-air chimney that pulls soot, moisture, and carbon monoxide into your active fireplace flue, accelerating creosote buildup and corrosion. In Lake Grove’s 1960s split-levels, we find this cross-draft scenario on a regular basis — it’s one of the most dangerous hidden conditions in converted homes. We inspect both flues with a chimney camera, seal abandoned flues with proper caps, and reline active flues with DuraFlex or HeatShield systems as needed. Call (888) 975-6389 for a dual-flue inspection — estimates are free.
Weekly use means annual sweeping is the minimum; we recommend inspection every 12 months and cleaning when creosote reaches 1/8 inch thickness. Lake Grove’s dense suburban canopy and coastal air add combustion byproducts and moisture that accelerate creosote formation compared to drier inland climates. Gary Murphy schedules Lake Grove cleanings from September through March to keep your system safe before peak burning season. Call (888) 975-6389 to book your annual service.
A stainless steel or copper cap with wind-resistant mesh and a minimum 5-inch skirt is the right choice for Lake Grove’s exposure to Atlantic-driven storms. We install Copperfield and Famco caps rated for coastal zones — not the lightweight galvanized units that rust through in three years. The cap must also properly cover dual-flue chimneys without creating draft interference between flues, a common installation error we correct in Lake Grove’s split-level housing. Call (888) 975-6389 for cap sizing and installation.
Isolated hairline cracks in otherwise sound tile can sometimes be sealed with HeatShield refractory mortar, but widespread cracking, spalling, or shifted tile sections require full relining with a stainless steel system. In Lake Grove’s 50-to-70-year-old chimneys, we more often find the latter — decades of freeze-thaw damage has simply exceeded repair limits. Gary Murphy will camera-inspect and show you exactly what you’re dealing with before recommending either approach. Call (888) 975-6389 for a liner evaluation.
Moss on the north side indicates chronic moisture retention in the masonry, which points to failed crown sealant, porous brick, or a compromised liner allowing condensation to saturate the structure. It’s not just cosmetic — in Lake Grove’s climate, that moisture drives freeze-thaw damage deeper every winter. We treat moss as a diagnostic signal, tracing the moisture source to its origin rather than just brushing it off. Call (888) 975-6389 and we’ll find out what’s really going on.
