Fast, Reliable Chimney Repair Across Melville
Chimney repair in Melville typically runs $850–$4,200 depending on whether you need mortar repointing, a full rebuild, or a stainless steel liner after an oil-to-gas conversion. Most Melville homeowners with 1960s–1980s colonials and split-levels call us when they notice brick spalling, crown cracks, or water stains on the ceiling around the chimney breast. We’re usually on site in Melville within 24–48 hours, and Gary Murphy handles the diagnosis personally. Call (888) 975-6389 for a free estimate.
We’ve been crossing the Long Island Sound to work in Suffolk County long enough to know Melville’s housing stock intimately. The executive suburbs along Route 110 and the neighborhoods branching off Old Country Road built out fast during the 1970s and 1980s, and those original clay-tile chimneys are hitting a critical maintenance window. If you live near the Strathmore gates, off Wolf Hill Road, or in the colonial clusters around Half Hollow Hills, there’s a decent chance your chimney has multiple flues serving both a fireplace and a converted heating system. That’s not a guess — it’s what we find on most Melville jobs.
Why Sterling Chimney Cleaning Bridgeport Is Melville’s Preferred Chimney Repair Company
More than 1,200 homeowners have trusted us across our service area, and our 4.7 average star rating from 1,234 verified reviews reflects the kind of accountability you get when Gary Murphy, the owner, is also the lead technician on your job. No dispatched crews, no rotating subcontractors. When you book a repair in Melville, you’re getting 14 years of exclusive chimney-trade focus brought directly to your roofline.
Our response time to Melville averages 24–48 hours for standard repairs, and we carry the materials to complete most jobs in a single visit. That matters on Long Island, where a cracked crown or failed flashing can turn into interior water damage fast during a nor’easter. We stock DuraFlex stainless liners, HeatShield crown repair mortar, and Copperfield flashing components on our truck — the brands professionals specify, not the retail-grade products that fail in three seasons.
We also understand the local conversion pattern. Melville sits in one of the highest oil-to-gas conversion zones in the country, and we’ve lost count of how many 1970s colonials we’ve opened up to find an abandoned oil flue still venting — or worse, not venting properly — alongside a fireplace flue with original clay tiles showing their age. That specific combination is practically a Melville signature, and diagnosing it correctly the first time saves you from a second service call and a second trip charge.
Our Chimney Repair Services in Melville
Chimney Rebuilding
When spalling brick, deteriorated mortar, and compromised structural integrity have gone past the point of spot repair, a partial or full chimney rebuild is the only safe option. In Melville, we see this most often on north-facing flues where decades of freeze-thaw cycling — driven by moisture from Long Island Sound and the Atlantic — have destroyed the outer wythe of brick. A typical rebuild on a Melville colonial runs $3,200–$4,200 for a partial rebuild up to the roofline, or $5,500–$8,000 for a full stack replacement including a new concrete crown. We handle the teardown, brick matching, and rebuild in-house, with Gary Murphy overseeing the structural work personally.
Mortar Repointing & Tuckpointing
Repointing is the surgical repair of deteriorated mortar joints before water infiltration destroys the brick itself. On Melville’s 40-to-50-year-old masonry, we find joints eroded to 3/8-inch depth or more — the threshold where repointing becomes urgent. Tuckpointing on a standard Melville colonial chimney runs $1,200–$2,400 depending on accessibility and the number of flues. We grind out the failed mortar to proper depth and repoint with type-N or type-S mortar matched to the original specification, not the quick-setting bag mixes that crack in the first freeze cycle.
Flashing Repair
Chimney flashing is the sheet-metal barrier where your chimney penetrates the roof, and it’s the single most common leak point we repair in Melville. The combination of coastal humidity, thermal expansion from unused summer flues, and the stepped rooflines common on split-levels creates separation at the flashing seams. We replace counter-flashing and step-flashing with Copperfield galvanized or copper components, sealed with high-temperature silicone and integrated with your roofing membrane. A standard flashing repair in Melville costs $650–$1,100, and we warranty our flashing work against leakage for five years.
Spalling Brick Repair
Spalling — the flaking and crumbling of brick faces — happens when moisture penetrates the masonry and freezes. Melville’s position between two bodies of water makes this worse than inland Suffolk County locations. We repair isolated spalling by removing damaged brick and installing matching replacements, then addressing the underlying moisture source with proper crown slope, wash, and waterproofing. Spot brick repair on a Melville chimney runs $450–$950 per area, depending on how many courses are affected and whether we need to source matching brick from a Long Island masonry supplier.
Chimney Waterproofing
After repointing or rebuild, we apply a vapor-permeable silane/siloxane sealer that lets the chimney breathe while blocking liquid water penetration. This is particularly valuable in Melville’s humid shoulder seasons, where internal condensation accelerates liner deterioration in flues that sit idle from May through September. Waterproofing a standard Melville chimney runs $350–$650 and extends the life of your mortar work by years.

Trusted Brands We Service in Melville
We don’t pull materials off a retail shelf. For Melville repairs, we stock DuraFlex stainless steel liners for gas-conversion relining, HeatShield ceramic refractory mortar for crown and flue resurfacing, and Copperfield flashing, caps, and dampers. These are the brands specified in chimney-professional supply houses, not the consumer-grade products you’ll find at big-box stores. That means when Gary arrives at your Melville home, he’s carrying the right material for a same-day repair instead of ordering parts and scheduling a return trip. On a recent job in the Strathmore section of Melville, we arrived to find a three-flue chimney system on a 1975 colonial: the main fireplace flue had spalling brick and a cracked clay tile, while the abandoned oil flue was oversized and unlined for the new gas boiler. We used a 7-inch DuraFlex stainless steel liner for the gas flue and repointed the crown with HeatShield mortar, completing the repair in one trip as promised.
Common Chimney Repair Problems We See in Melville Homes
- Freeze-thaw crown failure on north-facing flues. Melville’s exposure to moisture from both Long Island Sound and the Atlantic creates aggressive freeze-thaw cycling. We routinely find chimney crowns cracked completely through on north-facing exposures, where melting snow refreezes overnight and hydraulic pressure blows apart the concrete.
- Spalling brick from 40-year-old clay flue tiles. The original clay liners in Melville’s 1960s–1980s colonials have reached end-of-life. As they crack and shift, acidic condensate and combustion byproducts migrate into the surrounding brick, accelerating spalling and mortar deterioration.
- Abandoned oil flues after gas conversion. The oil-to-gas wave across Suffolk County has left countless Melville chimneys with oversized, unlined flues that were never properly decommissioned. These create draft hazards, condensation problems, and potential carbon monoxide exposure. We evaluate every flue system we open.
- Failed flashing at split-level roof transitions. The stepped rooflines common in Melville’s split-level stock create complex chimney penetrations with multiple flashing planes. Thermal movement and coastal humidity separate these joints faster than on simpler gable-roof designs.

FAQs — Chimney Repair in Melville
Almost certainly, yes. The oil flue in your Melville home was sized for a higher-temperature, higher-draft oil burner, and the new gas boiler produces cooler, wetter exhaust that condenses in that oversized flue. We find this exact scenario on the majority of 1970s colonials we inspect in the 11747 ZIP code. The unlined or improperly lined flue creates a draft hazard and accelerates deterioration of the clay tiles and surrounding masonry. A stainless steel liner sized specifically for your gas appliance — typically a 6-inch or 7-inch DuraFlex — is the correct repair. Call (888) 975-6389 and we’ll evaluate both flues during the same visit; estimates are free.
Clay liner safety depends on visible condition, not just age. In Melville’s humid climate, an unused flue accumulates moisture through the shoulder seasons, which accelerates clay tile deterioration even without active combustion. We inspect with a chimney camera to check for cracks, spalling, and shifting — common findings after 40–50 years. If the tiles are intact and properly aligned, continued use may be safe with annual inspection. If we find cracking or gaps, we recommend relining before the first fire. Call (888) 975-6389 to schedule a camera inspection; estimates are free.
For Melville’s coastal position between Long Island Sound and the Atlantic, we recommend annual inspection and cleaning for actively used fireplaces, and biennial inspection for venting systems serving heating appliances. The freeze-thaw cycling and high humidity here accelerate crown and mortar deterioration compared to drier inland climates. Catching crown cracks at 1/8-inch width prevents the $3,000 rebuild that follows when water penetrates and destroys the brick wythe. Call (888) 975-6389 to set up an annual maintenance schedule; estimates are free.
Yes, and we do this routinely on Melville split-levels where the lower roofline puts the crown in easy reach but also exposes it to more direct weather. For cracks under 1/4-inch with intact structural concrete, we resurface with HeatShield crown sealant at $650–$1,200. For crowns cracked through or sloped incorrectly toward the flue, we pour a new reinforced concrete crown with proper overhang and drip edge at $1,400–$2,200. The split-level roof configuration common off Wolf Hill Road and in the Strathmore area actually simplifies scaffold setup, which saves labor cost. Call (888) 975-6389 for a specific quote; estimates are free.
Yes, flashing replacement is one of our most common repairs in Melville’s colonial stock. We remove the existing step-flashing and counter-flashing, inspect the roof deck for water damage, and install new Copperfield galvanized or copper flashing integrated with your shingles and sealed with high-temperature silicone. A standard colonial chimney in Melville takes 3–4 hours and costs $650–$1,100. We warranty our flashing work for five years against leakage. Call (888) 975-6389 to stop the leak before it damages your ceiling; estimates are free.
