Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Our Chimney Repair Services in Williston Park
Mortar Repointing
Williston Park homes were mostly built with original lime-based mortar, which erodes faster than modern Portland cement. After 70 to 100 years of Long Island freeze-thaw cycles, those joints turn to sand. In Williston Park, we typically repoint chimneys for $225 to $700 depending on height and joint condition. We match the mortar color and composition so the repair doesn’t look like a patch. Waiting too long on repointing is the single most common way a Williston Park chimney becomes a rebuild project.

Spalling Brick Repair
Spalling is what happens when water gets into the brick and freezes, popping the face off. Williston Park’s proximity to the Long Island Sound adds salt to that moisture, so the spalling cycle runs faster here than in inland towns. We replace damaged bricks with salvaged matches where possible, or new brick graded to match the original color and texture on your Cape or Tudor. Spalling repair in Williston Park generally runs $300 to $1,200 per section depending on how many courses are involved.

Chimney Waterproofing
Waterproofing only works after we’ve repaired whatever the water already damaged. That’s the order of operations, and anyone who tells you to waterproof over crumbling mortar is selling you a bridge. On a Williston Park chimney, we use professional masonry treatments from Gelco or ChimneySaver, not hardware store silicone sprays. A proper waterproofing application after repointing runs $350 to $800 for a typical single-flue chimney, and it usually buys you 8 to 12 years before the next round of maintenance.

Flashing Repair
Flashing is the metal joint where your chimney meets the roofline, and it’s one of the most common failures we see across Williston Park’s 1920s-1950s housing stock. When flashing lifts or rusts through, rainwater tracks down inside the chase and silently soaks the mortar and the ceiling below. A simple flashing patch runs $250 to $500. Replacing rotted step flashing and the counter-flashing around the Chimney Cap & Crown - Williston Park runs $600 to $1,400. In a village where many houses are attached or tightly spaced, a leaking flashing on one chimney can become a shared-wall problem fast.

Common Chimney Repair Problems We See in Williston Park Homes
- Unlined or cracked clay-tile flues from the coal-to-oil conversion era. Most Williston Park chimneys were built for coal. When oil burners got dropped in, nobody relined the flue. Sixty years of acidic oil exhaust later, those tiles are cracked or gone, and carbon monoxide can sneak through the gaps into attached Capes and Colonials, often undetected until a camera inspection.
- Salt-driven spalling on exposed brick. The salt-laden air off the Long Island Sound accelerates the freeze-thaw spalling cycle on Williston Park chimneys. What starts as a few flaking bricks turns into a full crown rebuild if ignored for two or three winters. This isn’t cosmetic. Spalling is structural, and it lets water into the chase every single storm.
- Shared-chase cross-contamination. Many Williston Park pre-war homes have one brick chase with two flues side by side. The fireplace flue and the boiler flue share walls. When mortar between them fails, oil soot gets drawn into the fireplace draw and coats the smoke chamber and damper in acidic residue that eats mortar from the inside. We camera-inspect both flues together because that’s the only way to catch it.
- Crown failure on original masonry. The concrete crowns poured on 1940s chimneys in Williston Park are at the end of their service life. Hairline cracks let water in, freeze, and split the crown. A cracked crown is a $600 to $1,200 repair if caught early. A collapsed crown usually means partial rebuilding, and that runs $1,800 and up.

FAQs - Chimney Repair in Williston Park
Chimney Cleaning & Sweep in Williston Park removes creosote and soot. It does nothing for the flue lining itself. Most Williston Park chimneys were built in the 1920s through the 1950s with clay-tile liners sized for coal fireplaces. When oil burners were added later, the flues were often left unlined or undersized, and decades of acidic exhaust have cracked the tiles. A clean chimney can still be an unsafe one. We camera every flue before recommending relining, so you’ll see the cracks yourself. Call (516) 963-1068 for an inspection, no repair pressure attached.
Salt-laden air off the Sound accelerates spalling and mortar erosion by carrying corrosive moisture into brick and sitting there through repeated freeze-thaw cycles. Williston Park chimneys typically need repointing and crown attention about every 8 to 12 years compared to 12 to 15 years for homes further inland. The salt doesn’t cause the damage alone, but it speeds up whatever water was already getting in. If you haven’t had your crown checked in a decade, now is the season. Call (516) 963-1068 and we’ll put you on the route.
Yes, and this is exactly the kind of repair our Chimney Repair team does most often in Williston Park. We camera both flues at once to confirm where the cross-contamination is happening, then repair the mortar between them and resurface or reline whichever flue is cracked. We’ve done this on shared chases across the village, including the Tudors near Hillside Avenue where the two flues share a single narrow brick chase. The fix stops the oil soot from souring your fireplace draw. Call (516) 963-1068 for a camera quote, free estimates included.
We remove the old cracked concrete crown down to sound brick, form a new one with proper overhang and a drip edge, and pour it with a mix that expands and contracts with temperature swings without cracking. On a 1940s Colonial in Williston Park, that usually runs $800 to $1,500 depending on access and how much brick has to come out around the top. We’ll also check the flashing beneath it while we’re up there, since a crown failure on an older ridge-line Colonial often goes hand in hand with flashing rot. Call (516) 963-1068 and we’ll quote your chimney specifically.
Always before. Repointing closes the gaps. Waterproofing then protects the closed surface. If you waterproof over open mortar joints, you’re sealing moisture behind the barrier and turning the freeze-thaw cycle into a silent brick breaker. We repoint, let the new mortar cure, and only then apply the waterproofing treatment with Gelco or similar professional masonry products. In Williston Park’s salt-driven climate, this order of operations is the difference between a repair that lasts and one you’ll pay for twice. Call (516) 963-1068 to get on the schedule before spring rains arrive.
Williston Park’s Chimney Problem Is a Pattern, Not a Mystery
Here’s what makes Williston Park different from every other town on our service map. The village was built out almost entirely between the 1920s and the 1950s. That means the housing stock is unusually uniform in age, which means the chimneys are uniform in age, which means the failure modes repeat house after house. The original masonry flues were built for coal. Then someone dropped an oil burner into the basement and ran the exhaust through a flue that was never relined for it. Sixty years later, those clay tiles are cracked, the mortar joints are sand, and the crowns are done.
Wendell and his crew see the same deterioration pattern on one Williston Park street after another: crumbling mortar joints, undersized or unlined oil-burner flues, and crowns at end-of-life all at the same time. That’s why this village is a relining market more than a sweeping market. It’s also why the upsell artists love working here. They know a camera-shy contractor can tell a Williston Park homeowner their flue is “dangerous” and quote a $5,000 liner without showing a single image. We don’t work that way. The camera footage and a plain-English verdict, every time, no exceptions.
On a Tudor Revival near Hillside Avenue, we found a shared brick chase with two flues, one for the wood-burning fireplace and one for the oil boiler. Camera inspection showed third-degree creosote in the fireplace flue and a cracked clay-tile liner on the boiler side. Mortar between the two flues had spalled, so oil soot was bleeding into the fireplace draw. We installed a DuraFlex stainless steel liner on the boiler flue, HeatShield resurfaced the fireplace flue, and we repointed the chase with matching mortar before waterproofing the crown. The draft came back, the soot bleeding stopped, and the homeowner now has both flues on camera for any future inspector.
