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.
Fast, Reliable Chimney Repair Across Dix Hills
Chimney repair in Dix Hills usually means one of two things: water getting in where it shouldn’t, or a flue that’s no longer safe to burn. We handle both, and we’ve been doing it long enough to know exactly what Long Island’s salt air and 50-year-old masonry do to a chimney. Call (516) 968-5380 and Wendell or one of his crew will give you an honest read before any work is quoted. We serve all of Dix Hills including neighborhoods off Vanderbilt Parkway, Deer Park Avenue, and Half Hollow Road.
Why Top Hat Chimney Is Dix Hills’s Preferred Chimney Repair Company
Wendell Pike founded Top Hat Chimney in 1999, and he’s still the one answering the phone most nights. That matters in Dix Hills, where word travels fast and a chimney that drafts poorly is common knowledge by the next block party. We’re not a franchise that rotated a crew in from out of state. We know the colonials off Burr’s Lane, the split-levels near Otsego Elementary, and the ranches tucked behind the Half Hollow Hills library. The houses here were built for Long Island winters and oil heat. That specific housing stock is why we carry the repair materials we carry.
Our Dix Hills customers don’t get a call center. They get a live person at (516) 968-5380, twenty-four hours a day. They get a written estimate before work starts, and they get a 90-Day Done Right Promise stamped on the invoice: if it’s not right, one call brings us back at no charge. Ask anyone on your street. A good portion of our Dix Hills work comes from neighbors telling neighbors.
We also know this market’s prices. We’re not the cheapest, and we won’t pretend to be. We charge a fair rate for work done correctly the first time, with the camera footage to prove it. For Dix Hills homeowners who’ve been quoted one price on the phone and another at the door by a national outfit, that’s usually the moment they stop shopping.
Our Chimney Repair Services in Dix Hills
Most Dix Hills homes have chimneys built between 1965 and 1985, which means the mortar is now 40 to 60 years old. Here’s what we see most often, and how we fix it.
Flashing Repair
Flashing is the metal where the chimney meets the roofline, and in Dix Hills it takes a beating. Nor’easters drive rain sideways, and salt air off the Sound and the Great South Bay corrodes flashing faster than inland markets ever see. When flashing fails, water follows the chimney down into the attic and along the ceiling. We replace it with proper step and counter flashing, sealed correctly, not just caulked over. A flashing repair in Dix Hills typically runs $450-$850 depending on how much of the old metal has to be removed.

Mortar Repointing
Repointing is the careful work of removing deteriorated mortar joints and replacing them with fresh mortar that matches your home’s brick. Dix Hills chimneys from the 1960s and 1970s were often built with a softer mortar mix than modern standards, and salt air accelerates the erosion. You’ll see the joints start to look sandy and recessed. Left alone, water gets behind the brick and freezes, pushing the face off the chimney. Repointing in Dix Hills runs $25-$45 per square foot, and a typical repair section is $800-$1,600.

Spalling Brick Repair
Spalling is when the brick face itself flakes or pops off, and it almost always follows water intrusion. A chimney with spalling brick has had moisture inside the masonry that freezes and expands. On a Dix Hills colonial with two flues and a wide chimney mass, spalling usually starts near the top where exposure is worst. We remove the damaged brick, replace with matched units, and address the water entry point. Spalling brick repair in Dix Hills ranges from $600 for a small repair to $3,000+ for significant rebuild sections.

Chimney Waterproofing
Waterproofing is the best dollar-for-dollar protection you can buy for an older Dix Hills chimney. We apply a vapor-permeable masonry sealer that keeps rain and snowmelt out while still letting the brick breathe. If the chimney can’t release moisture, the sealer does more harm than good. That’s why we use a product rated for masonry chimneys, not paint. Full chimney waterproofing in Dix Hills runs $450-$700 for a typical colonial chimney, and it buys you years of slower deterioration.

Trusted Brands We Service in Dix Hills
We stock parts from Copperfield, DuraFlex, and HeatShield because those are the brands we trust to hold up on Long Island chimneys. If you have a Copperfield cap that’s rotted through, we can match it. If your clay-tile liner is cracked, DuraFlex stainless or a HeatShield resurfacing system may be the right call for your Dix Hills home. We don’t push one product. We’ll show you the footage and tell you what we’d put in our own chimney. Local stock means most common repairs in Dix Hills are done the same visit, not three weeks after we order a part from a warehouse in Ohio.
Common Chimney Repair Problems We See in Dix Hills Homes
- The neglected second flue. Many Dix Hills colonials have two fireplaces sharing one chimney chase, each with its own clay-tile flue. Homeowners service the flue they burn in and forget the other one exists. Then we find squirrel nests, dead birds, or years of glazed creosote blocking the second flue entirely.
- Oil-to-gas conversion damage. As Dix Hills homes switch from oil to high-efficiency gas, the old furnace flue becomes oversized for the new appliance. The flue never gets hot enough, condensation builds, and that acidic water eats clay-tile liners and mortar from the inside out. If you converted your furnace in the last few years and never had the chimney inspected, do it now.
- Salt-air corrosion. Dix Hills sits between the Sound and the Bay, and that persistent salt air means chimney caps and flashing corrode years sooner than in, say, upstate New York. We regularly replace caps that are rusted through while the bricks themselves are still sound.
- Glazed creosote after a hard winter. When a nor’easter knocks out power for a week, even the decorative fireplace gets pressed into service. If that flue wasn’t swept in a year or two, the creosote from a week of hard burning can glaze over into a fuel deposit that a brush alone won’t remove. That’s a fire hazard, full stop.

FAQs - Chimney Repair in Dix Hills
You don’t know, and that’s the problem. A flue that hasn’t been used in years is exactly where we find animal nesting, dead birds, heavy creosote from old fires, or a cracked clay-tile liner that’s been slowly failing. The only way to know is a camera inspection. We run a camera down both flues on every Dix Hills chimney repair call, whether you burn in that fireplace or not. Call (516) 968-5380 and we’ll show you the footage.
Yes. In fact, that’s exactly the kind of dual-flue Dix Hills chimney we work on most weeks. The furnace flue that used to carry oil exhaust is now oversized for a high-efficiency gas unit, which means condensation and liner damage. The fireplace flue may be fine, or it may need its own repair. We inspect both, repair both, and give you one honest report for the whole chimney. So should Wood or oil. Call (516) 968-5380 and we’ll schedule both inspections in one visit.
Fifty years is old for a mortar crown, especially in Dix Hills where winter freezes and salt air work on it every year. The crown is the concrete or mortar cap on top of the chimney that sheds water. When it cracks, water goes straight into the masonry. A proper replacement crown with an overhang and a weep edge solves it. We rebuild crowns regularly in Dix Hills, and it’s one of the best preventive repairs you can make before spalling brick starts. Call (516) 968-5380 for a crown inspection with your next sweep.
If your wood stove is your primary heat source, sweep every cord of wood you burn, or at minimum every 60 days during burn season. That’s a much shorter interval than a decorative fireplace, but a wood stove burning heavily loads a flue with creosote fast. First-degree creosote is a brush job. Third-degree is a glaze. Catch it early. We’ll set a sweep schedule that matches how much you actually burn, and we’ll repair any liner damage we find before it becomes a full reline. Call (516) 968-5380 and we’ll work it out with you.
Yes, and it’s part of every chimney repair inspection we do in Dix Hills. The smoke chamber is the sloped section above the firebox where smoke passes before entering the flue. On a 50-year-old Dix Hills colonial, that area is often cracked, missing mortar, or caked with creosote. It’s one of the most common places for heat to escape into the house framing. We inspect it with a camera on every job and repair or parge it as needed. Call (516) 968-5380 to schedule a full camera inspection of your chimney, top to bottom.
If your chimney is leaking, your brick is spalling, or you’ve just never had that second flue looked at, don’t put it off. Wendell and his crew have been repairing Long Island chimneys since 1999, and we’re known in Dix Hills for honesty that goes beyond the easy answer. Call (516) 968-5380 for a free estimate. You’ll get a real person, a straight answer, and a chimney that’s safe to burn in.
