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.

Wendell Pike and his crew have worked these streets long enough to know what a 1960s Cape Cod chimney should look like inside, and what it shouldn’t.

Why Top Hat Chimney Is Islip Terrace’s Preferred Chimney Repair Company
We’ve been around since 1999, which means we’ve seen what three decades of Long Island weather does to the chimneys in this hamlet. Homeowners here tell us the same thing over and over: some national outfit quoted a price over the phone, sent a stranger, then tripled the number standing in the living room. That’s not how we work. The price you hear is the price on the invoice. Wendell puts his name and license number on every job, and the 90-Day Done Right Promise is stamped in writing. If it’s not right, one call brings him back. No runaround, no call center.
When you call Top Hat Chimney, a live person answers. Every hour, every day. It might be Wendell himself. And when the crew heads to your street off Connetquot Avenue or around Sunrise Highway, you’ll get a real arrival window. If traffic snarls up, we call you. You won’t sit around wondering.
People in Islip Terrace have been good to us, and we’ve earned that by telling the truth. Sometimes that truth is “your chimney needs a sweep, not a repair.” We’ll show you camera footage either way, and give you a plain-English verdict before a single tool comes off the truck. That’s just how Chimney Repair ought to be done.
Our Chimney Repair Services in Islip Terrace
Mortar Repointing
Those 1950s and 1960s chimneys running through the center of Islip Terrace Capes and ranches were built with lime-based mortar that’s now 60 to 70 years old. Freeze-thaw cycles off the bay work water into every joint, and once the mortar starts crumbling, bricks shift and water gets to the flue. Repointing in Islip Terrace usually runs $400-$1,200 depending on how much of the stack needs work. We grind out the old joints, pack in fresh mortar matched to the original, and the chimney stands straight for another few decades.
Spalling Brick Repair
Spalling is when the face of a brick flakes off, usually from water soaking in and freezing. Islip Terrace’s humidity off Great South Bay accelerates that cycle. We replace the spalled brick with matching stock, repoint around it, and often recommend waterproofing so it doesn’t happen again the following winter. Most spalling repairs around here run $300-$800.
Chimney Waterproofing
The crown and brick work on an Islip Terrace chimney take a beating from nor’easter-driven rain followed by hard freezes. Waterproofing with a breathable sealant keeps water out while letting the masonry release moisture that’s already inside. It’s one of the most cost-effective repairs we do, typically $350-$700 for a full application on a standard single-flue chimney. We use Gelco and Olympia Chimney products because they hold up in Suffolk County’s climate.
Flashing Repair
When Islip Terrace homeowners see water staining the ceiling near the chimney, the flashing is usually the culprit. Original flashing on these mid-century homes was often galvanized steel, and 60 years of salt air and thermal expansion tears it apart. We fabricate and install new flashing, typically $450-$950, including the roof-to-chimney seal. It’s a job that must be done right the first time, because a bad flashing repair soaks the framing and the smoke chamber below.

Trusted Brands We Service in Islip Terrace
We install and service liners, caps, and waterproofing products from DuraFlex, Copperfield, and Famco. These are the brands that hold up to what an old oil-era flue in Islip Terrace throws at them: acidic condensation, wet winters, and occasional wood smoke toggling the system between hot and cold. Because we work with these products every day, we keep the common parts on the truck. That means when we find a cracked liner on a Cape Cod off Spur Drive North, we can usually fix it the same day rather than waiting a week for parts.
Common Chimney Repair Problems We See in Islip Terrace Homes
- Gas conversion condensation eating the old clay liner. When an oil boiler gets swapped for gas, the new appliance vents cooler exhaust into a flue sized for oil. That exhaust condenses inside the chimney, and the acidic moisture eats the clay tile from the inside out. Owners never see it until we send the camera up.
- Freeze-thaw cycles wrecking the exposed crown. Nor’easters soak the masonry, then a hard freeze expands the water. Repeat that a dozen times a winter and the crown cracks, spalls, and lets water down into the smoke chamber.
- Creosote glazing from occasional fireplace use. A cold, oversized flue can’t build draft for wood smoke, so the smoke lingers and the creosote bakes into a hard glaze. Left alone, it becomes a chimney fire risk even if the fireplace only gets lit a few times each January.
- Crumbling mortar from six decades of humidity. Islip Terrace’s closeness to the bay keeps moisture in the air year-round, and that moisture works into old lime mortar joints, leaving gaps for water and draft loss.

FAQs - Chimney Repair in Islip Terrace
Gas exhaust is cooler than oil exhaust, and your flue was sized for oil. Cooler exhaust means condensation inside the chimney, and that condensation attacks the original clay tile liner. Over time the tile cracks and the flue becomes unsafe, even if the fireplace never gets used. A properly sized stainless liner fixes the draft and stops the acid attack. We’ll show you the camera footage before anything gets sold to you. Call (934) 935-3847 and we’ll set up a camera inspection, free inside the county.
Yes, and honestly the few-times-a-year pattern is what makes it worse. Those occasional fires burn cool in an oversized flue, so creosote builds up and glazes rather than drying out. Once a year, burn or no burn. Chimneys break in the off-season too. A sweep costs less than a quarter of what a liner replacement does, and we’ll know early if the fireplace is heading toward trouble. Call (934) 935-3847 to book a sweep before burning season.
The camera and a close look at the crown will tell us in about fifteen minutes. Hairline cracks can be sealed and waterproofed for a few hundred dollars. If the crown has deep cracks, pieces missing, or is pulling away from the flue, a rebuild is the honest fix. We’ll show you the photos and give you both options with real numbers. No camera footage means no repair recommendation, every time.
In most cases, yes. We reline the flue with a DuraFlex stainless liner pulled down through the chimney, sized to match your gas appliance and any fireplace use. No demolition, no bricks flying, no need to tear into the wall. We did exactly that on a 1960s ranch off Connetquot Avenue last fall. The homeowner had a cracked tile we could see on camera, and after the reline the draft stabilized. Call (934) 935-3847 for a free estimate.
They assume the old chimney is fine because the gas appliance vents “cleaner” than oil did. The flue doesn’t know the difference. Cooler gas exhaust condenses, the clay tile erodes from the inside, and nobody sees it until a leak or a chimney fire. The mistake is skipping inspections just because the fireplace gets used rarely. Once a year, burn or no burn, and a camera inspection on any home built before 1980. Call (934) 935-3847 and we’ll get you on the schedule.

If your chimney is over 50 years old, there’s almost certainly something happening inside it that you haven’t noticed. That’s not a scare pitch, it’s just math.

We’ll put a camera up there, show you exactly what we see, and tell you plainly what needs doing and what can wait. Nothing gets recommended without camera evidence you can look at yourself. Call (934) 935-3847 for a free estimate, and you’ll talk to a real person, not a voicemail box.
