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.

AfterFast, Reliable Chimney Repair Across North Merrick
Chimney repair in North Merrick typically runs $225-$650 for repointing and flashing work, and $1,800-$4,200 when a flue liner replacement or partial rebuild is needed. Most jobs are completed in a single day. If you’re noticing crumbling mortar, spalled bricks, or a musty smell near your fireplace, call (516) 963-1068 and Wendell will walk you through what you’re seeing before anyone schedules a visit.
We work North Merrick’s post-war Capes, split-levels, and ranches all year long. These homes, most built between 1945 and 1965, have chimneys that are now 60 to 80 years old. The flues inside them were sized for oil-fired furnaces, and Nassau County’s gas conversions have changed how those flues breathe. That’s not a generic talking point. It’s the reason we see specific, repeatable failures on North Merrick chimneys that newer towns simply don’t have.

Wendell Pike started Top Hat Chimney in 1999, and he’s been inside more North Merrick chimney stacks than he can count. When you call, a live person answers. Not a voicemail box, not a call center.

It’s stamped on your invoice. We also give upfront pricing before a single tool comes off the truck, and the number you hear on the phone is the number on the invoice.

Mortar Repointing
North Merrick chimneys from the 1950s were originally pointed with soft lime mortar. Somewhere along the way, well-meaning homeowners repointed with hard Portland cement from the hardware store. That cement traps moisture behind the joint, and North Merrick’s salt-laden bay humidity turns that trapped water into spalled brick faces within a few winters. We cut out the bad joints and repoint with a softer lime-based mix that lets the wall breathe. Typical repointing in North Merrick runs $225-$600 depending on how much of the stack is involved.
Spalling Brick Repair
Spalling is what happens when water gets into the brick face and the surface pops off. On streets off the Southern State Parkway and up toward Merrick Avenue, we see it on exposed chimney crowns and upper courses battered by freeze-thaw cycles coming off Merrick Bay. A crowned, spalled top course is not a structural emergency most days, but it is a countdown. We replace the damaged brick and address the water source so you’re not doing this again in three years. Expect $350-$900 depending on the number of bricks and whether scaffold is needed.
Flashing Repair
Flashing is the metal seal where the chimney meets the roof line. On North Merrick’s split-levels with sloped roofs, it gets pulled and stressed by ice dams and gutter runoff every winter. When flashing fails, water follows the chimney down into the attic and wall cavities. We pull back shingles, replace the step and counter flashing, and seal with a proper weatherproof barrier. Flashing repair in North Merrick runs $400-$850 for a standard one-story roof line.
Chimney Waterproofing
Once we’ve done the repair work, waterproofing is the cheap insurance that keeps it done. We apply a vapor-permeable siloxane sealer that blocks liquid water but lets the brick breathe. Given North Merrick’s proximity to the South Shore bays and the humidity that comes with it, a waterproofed chimney crown and stack lasts noticeably longer here than it does inland. Budget $225-$400 for a full application.

Trusted Brands We Service in North Merrick
Our crew installs and services liners and components from DuraFlex, Olympia Chimney, and Famco. We stock common North Merrick parts on the truck, which means when a 1950s Cape off Lynn Lane needs a crown rebuild or a liner section, we’re not ordering parts and coming back next week. The specific brands we trust are the same ones that hold up in salt-laden bay air and freeze-thaw cycles.
Common Chimney Repair Problems We See in North Merrick Homes
Here are the four things we find over and over on North Merrick chimneys:
- Gas-converted oversized clay flues. Your 1955 chimney was built for an oil furnace that pushed hot exhaust up a big flue. That gas furnace you installed in 2010 runs cooler. The cooler exhaust condenses inside the oversized flue, and the acidic condensate eats mortar joints and clay tile from the inside out. You won’t see it from the ground. A camera will show it in ten minutes.
- Salt-driven spalling. North Merrick sits only a couple of miles north of the bays. Salt-laden humidity blows in constantly, settles into porous brick, and accelerates mortar erosion. Then winter’s freeze-thaw cycles do the rest. What lasts 40 years in Garden City may only last 20 here.
- Abandoned dual flues. A lot of North Merrick Capes have two flues, one for the fireplace and one for the old oil furnace. When oil got ripped out for gas, the furnace side became an orphan. Nobody looks in it for two decades. Then you use the fireplace for the first time in ten years and the draft is dead because a raccoon or squirrel built a nest in the abandoned flue.
- 1980s hard-cement repointing. North Merrick has a lot of DIY repointing from the 1980s and 90s done with the wrong mortar. That hard cement traps moisture behind the surface. In bay humidity, the brick face blows off within a few winters. We see this regularly and it’s one of the most misdiagnosed problems in town.

FAQs - Chimney Repair in North Merrick
Because it was likely repointed with hard Portland cement instead of a lime-based mortar. Hard cement traps moisture behind the joint, and North Merrick’s salt-laden bay humidity keeps that moisture active through every freeze-thaw cycle. The brick face eventually pops off. We grind out the old cement and repoint with the right lime-based mix. If you’re seeing spalling, call (516) 963-1068 and Wendell will give you a straight read on whether it’s cosmetic or structural.
Because your flue was sized for oil, not gas. Oil exhaust runs hot and shoots up the oversized clay flue. Gas exhaust runs cooler and condenses inside that same flue, creating acidic moisture that eats mortar joints and cracks clay tiles invisibly. The only way to confirm the damage is a camera inspection. We do a Level 2 camera inspection and show you the footage. Nothing gets recommended without evidence you can see for yourself.
Salt-laden humidity is the big one. It accelerates mortar joint erosion and brick face spalling on exposed chimney crowns and upper courses. North Merrick chimneys need annual crown and flashing inspections more than inland towns because the salt weakens the mortar and freeze-thaw cycles finish the job. A chimney that would last another decade in Westbury may need crown work years earlier here.
Yes, because the furnace flue doesn’t know it’s been abandoned. If your house was converted to gas and that second flue now vents nothing, it’s been sitting open for years collecting moisture, animal nests, and maybe a cracked tile or two. When you do use the fireplace, the abandoned flue can block proper draft or even hide a carbon monoxide path. We camera both flues on every inspection. Call (516) 963-1068 for a free estimate, and ask about our no-trip-charge service in the county.
Repointing removes and replaces the mortar joints between bricks. A rebuild replaces the bricks themselves when they’re too spalled, cracked, or structurally compromised. If the damage is in the masonry, not just the joints, repointing won’t hold. We camera the flue and inspect the full stack, then show you exactly what needs to happen and why. Some repairs can wait a season. Some can’t. We’ll tell you which one you have.
