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 Lynbrook
Chimney repair in Lynbrook, NY typically runs $350-$950 for mortar repointing, $600-$1,800 for flashing repair, and $2,500-$6,500 for full flue relining. Most jobs are completed in a single visit. Salt air off Jamaica Bay eats at mortar and brick faster here than most homeowners realize, so if you’ve noticed crumbling joints, a rusted cap, or water staining near the chimney, the sooner we look, the less it costs. Wendell Pike has run Top Hat Chimney since 1999, and he’ll send a crew that knows Lynbrook’s housing stock from the inside out. Call (516) 604-2573 for a free estimate.
Why Top Hat Chimney Is Lynbrook’s Preferred Chimney Repair Company
Wendell started Top Hat Chimney in 1999, and in the 26 years since, he’s been inside enough Lynbrook chimneys to know what fails first on a 1930s brick colonial versus a post-war Cape Cod. Homeowners here tell us the same thing: they’re tired of companies that send a different stranger to the door every season and vanish when the fix doesn’t hold. That’s not how we work. Wendell’s name is on the truck, his license number is published, and if the repair isn’t right, the 90-Day Done Right Promise means one call brings the crew back. No fine print, no runaround.
Local knowledge matters for Chimney Repair in this village. Lynbrook’s blocks are tight, the homes are old, and the chimneys were built for a heating system most of them no longer use. A sweep who only knows new construction will misread what he’s seeing. Our crews know the difference between a mortar joint that’s weathered from seventy years of salt wind and one that’s failed because acidic condensate has been eating it from behind. That difference changes whether you need a $400 repoint or a $3,000 liner job. We’ll show you the camera footage either way.
Phones are answered by a live person around the clock. Not a call center, not a voicemail box. Sometimes it’s Wendell himself picking up at 11pm. For repairs over $200, take $40 off. Seniors and veterans always get 10% off. And if you’ve got a written estimate from another company, bring it to us for a free second opinion before you spend a dime.
Our Chimney Repair Services in Lynbrook
Mortar Repointing
When the mortar between your bricks crumbles, water gets in, freezes, and pries the joints apart further. Lynbrook’s salt air accelerates this, especially on the south-facing side of a stack that takes the worst of the wind off the bay. Repointing removes the old, failed mortar and tucks fresh material in. In Lynbrook, expect to pay $350-$950 depending on how many courses need work and whether we’re on a ladder or staging. Catch it early and it’s a one-day job.
Spalling Brick Repair
Spalling is what happens when bricks themselves start flaking, cracking, or losing their face. It’s farther along than repointing. Once a brick’s surface is gone, moisture gets deeper into the chimney, and you start losing structural strength. In Lynbrook we see this most often on chimneys that haven’t been sealed and have taken decades of salt-laden air. Individual brick replacement runs $75-$150 per brick in this market, while a larger spalling repair across a full stack face can run $900-$2,200. We’ll tell you honestly if a few bricks will fix it or if the section needs rebuilding.
Chimney Waterproofing
A chimney cap keeps rain out of the flue, but it does nothing for the brick and mortar below. Waterproofing treats the masonry so water beads off instead of soaking in. Given Lynbrook’s coastal exposure, we recommend it more here than we do in inland Nassau villages. A full chimney waterproofing with a breathable masonry sealer runs $250-$600 in Lynbrook. It’s one of the cheapest things you can do to extend the life of a 90-year-old chimney.
Flashing Repair
Flashing is the metal where the chimney meets the roof. When it fails, water travels down the chimney into the attic and along the roof deck, and you won’t see it until the stain shows on a ceiling. Nor’easters have torn up plenty of flashing around Lynbrook over the years, and the salt air corrodes it faster than you’d think. Flashing repair in Lynbrook typically runs $600-$1,800, depending on whether we’re replacing a single step flashing or doing a full base and counter-flashing with new copper or galvanized. We never caulk over failed flashing and call it done.

Trusted Brands We Service in Lynbrook
We install and service DuraFlex stainless liners, Copperfield caps and crowns, and HeatShield resurfacing systems. If you’ve got a liner that’s been patched by another company and you’re not sure it’s right, we’ll run a camera down and show you exactly what’s there. For Lynbrook’s older homes, we tend to recommend DuraFlex stainless more often because it stands up to the acidic condensate you get from converted oil-to-gas flues better than aluminum. We keep common cap sizes and flashing materials on the truck so most Lynbrook jobs don’t need a second visit.
Common Chimney Repair Problems We See in Lynbrook Homes
- Cracked clay tile liners from oil-to-gas conversions. When an old oil boiler was swapped for a gas furnace without relining, the oversized flue cools exhaust too fast. Acidic moisture condenses inside and cracks the tile. We’ve found this in a large share of Lynbrook’s 1920s-1950s homes.
- Eroded mortar joints and spalling brick from salt air. The prevailing winds off Jamaica Bay push salt-laden air into Lynbrook’s masonry. It gets into the mortar, accelerates freeze-thaw damage in winter, and leaves brick faces popping off. South-facing stacks go first.
- Failed flashing from Nor’easters and age. Original flashing on a 70-year-old chimney has outlived its usefulness. Once the seal breaks, water gets behind the brick and you’ll see efflorescence, peeling paint, or a damp smell near the fireplace.
- Cracked crowns from water pooling. A crown that’s level instead of sloped will hold water. In a coastal climate with a hard freeze cycle, that means cracking. We rebuild crowns with a proper overhang and waterproof the surface.

FAQs - Chimney Repair in Lynbrook
Because the flue is oversized for the gas appliance. An oil boiler needs a large flue to handle the exhaust volume. A modern gas furnace produces a much smaller, cooler exhaust stream. When that stream hits an oversized clay tile flue, it cools quickly and condenses acidic moisture inside the flue. That acid eats the clay tile from the inside out, cracking it section by section. In Lynbrook, the problem is worse because salt air is simultaneously attacking the mortar from outside. So the chimney fails from both directions at once. The fix is a properly sized stainless liner, and in this village, we install DuraFlex more than any other brand.
Every year, once a year, burn or no burn. Chimneys break in the off-season too. But given Lynbrook’s position a few miles from the South Shore with salt-laden wind and the occasional Nor’easter, we recommend an annual look at the crown and flashing, not just the flue. A crown crack the width of a quarter lets in more water than most people realize. Our annual inspections include a camera run and a photo report. If you’ve never had the crown and flashing looked at, this is the year to start.
Salt air damages brick and mortar the same way it damages a car body: slowly, then all at once. The salt crystals penetrate the porous surface of the mortar, then during freeze-thaw cycles they expand and break the bonds. Lynbrook gets this worse than inland Nassau villages because the prevailing wind carries it straight up from Jamaica Bay. You’ll see it first as white efflorescence on the brick, then crumbling mortar, then spalled brick faces. The good news is it’s preventable with waterproofing and regular repointing.
For the homes built before World War II, it’s the flue liner, hands down. A 1920s or 1930s brick colonial in Lynbrook was almost certainly built for oil or coal. When the house switched to gas, the original clay tile liner stayed. It’s now 80 to 100 years old and probably cracked from acidic condensate, even if the outside of the chimney looks fine. We find this on a large percentage of the pre-war homes we inspect in this village. The second most common is crown rebuilds from salt and water damage.
Yes. A cap covers the flue opening, but the brick and mortar below still get hit by rain, snow, and salt-laden wind. Waterproofing seals the masonry itself. In Lynbrook’s coastal environment, a cap by itself is not enough to stop the freeze-thaw damage we see on south-facing stacks. Waterproofing runs $250-$600 and adds years to the structure. Call (516) 604-2573 for an exact quote; we’ll assess whether your masonry has already absorbed too much moisture to seal this year.
