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 Cleaning & Sweep Across Uniondale
If you live in Uniondale and haven’t had your chimney swept in a year or more, the short answer is: you’re overdue, and it’s not your fault. Uniondale’s post-WWII Cape Cods and ranches were built for oil heat, converted to gas decades ago, and the flues inside them were never resized for the change. That means what looks like a simple cleaning job is often the moment we find cracked clay tiles, acidic condensate damage, or a flex-liner patch from 1987 that was never permitted. At Top Hat Chimney, Wendell Pike and his crew work Uniondale every week. Call (516) 963-1068 and you’ll get a live person, an honest quote, and a sweep who knows exactly what he’s looking at when he walks through your door.
Why Top Hat Chimney Is Uniondale’s Preferred Chimney Cleaning & Sweep Company
We’ve been at this since 1999, and Uniondale is the kind of place where a chimney company earns its reputation one cul-de-sac at a time. Wendell puts his name and license number on every job, and his 90-Day Done Right Promise is in writing. If the work isn’t right, one call brings him back. That’s not a marketing line. That’s how he’s kept customers from Jerusalem Avenue to the blocks around Uniondale Avenue for over 29 years.
You won’t get a call center when you phone us. You’ll get a live person, around the clock, and it may well be Wendell himself picking up. When he quotes you a price, that’s the number on the invoice. No “discoveries” after the tools come off the truck that suddenly double the bill. Ask anyone on your street. The folks who’ve used us once tend to call us back every year, because they know the sweep who shows up at their door is the same guy who’ll be at the hardware store on Saturday.
Our Chimney Cleaning & Sweep team arrives in uniform, background-checked, with a real arrival window. If we’re running late, we call. That matters when you’ve taken a morning off work to meet us in Uniondale. And because we’re owner-operated, not a franchise that rotated in last spring, we remember your chimney from the year before. We notice when the mortar joint that was starting to go last season has gotten worse. That’s the difference between a service call and a sweep who actually knows your house.
Our Chimney Cleaning & Sweep Services in Uniondale
Level 1 Inspection
A Level 1 inspection is the standard once-a-year check when nothing has changed about how you use your fireplace or stove. In Uniondale, though, “once a year” is the floor, not the ceiling. We’re checking the accessible portions of the flue, the firebox, the damper, and the cap. But given the age of Uniondale’s housing stock, the real value is the camera footage we take and the plain-English verdict Wendell gives you afterward. Every time, no exceptions. Your flue doesn’t care how the fire looks. It cares how it breathes.

Level 2 Inspection
A Level 2 inspection goes further, and in Uniondale it’s the one we recommend most often. It’s the inspection required before a real estate transfer, after a chimney fire, or when you’ve converted your heating system. And here’s the local truth: Nassau County’s oil-to-gas conversion wave in the 1980s and 1990s prompted a lot of homeowners to have cheap flex-liner patches installed without permits. Current county code requires a permitted, properly sized stainless liner. A Level 2 inspection is how we document what’s really in there, so a hidden patch doesn’t stall your closing. If you’re selling a Uniondale ranch or Cape, schedule this before you list. It’s cheaper than a deal falling apart.

Creosote Removal
Creosote is the byproduct of incomplete combustion, and Uniondale’s wood stoves build it faster than most. The salt air coming up from the South Shore doesn’t help, and neither does burning unseasoned wood, which we see a lot of. First-degree creosote is a brush job. Third-degree is a glaze, and a brush won’t touch it. It has to be removed chemically or with specialized rotary tools. The honest truth is that if you’re burning green wood in a tight Cape Cod off Uniondale Avenue, you may need sweeping every 40 to 50 burns rather than once a year. Wendell will tell you straight: when the buildup is dense and sticky, a standard sweep leaves you with a false sense of safety.

Soot Removal
Soot is the fluffy black powder from wood smoke. It’s less concentrated than creosote, but it coats the flue walls and reduces draft. In Uniondale’s coastal air, soot also attracts moisture, which turns it into an acidic paste that eats at old clay tile liners from the inside. We remove soot as part of every sweep, then run the camera to check what the soot was hiding. On a 60-year-old Uniondale chimney, that second step is the one that matters.

Trusted Brands We Service in Uniondale
We install and service liners and components from DuraFlex, Gelco, Olympia Chimney, and Copperfield. We keep common parts for Uniondale’s older chimneys on the truck, which means less waiting when we find a damaged cap or a failing liner section. If your home has a DuraFlex liner that’s showing age or a Gelco patch that was never properly sized, we’ll show you the camera footage and walk you through what actually needs doing. Sometimes the answer is “not yet.” Wendell will tell you that too.
Common Chimney Cleaning & Sweep Problems We See in Uniondale Homes
- Salt-eaten mortar joints on post-WWII chimneys. Uniondale sits roughly 8 miles north of the Atlantic South Shore, and that salt-laden air accelerates mortar erosion and brick spalling. A flue with crumbling joints isn’t draft-safe, no matter how clean it looks inside. We’ve swept chimneys here where the mortar was so far gone the flue had begun to shift.
- Unpermitted flex-liner patches from the 1980s-90s gas conversions. When Uniondale homeowners switched from oil to gas, many had cheap flex liners installed without permits. Those undersized liners don’t meet current Nassau County code, and they routinely block a real estate closing. We find them on inspections all the time.
- Third-degree creosote glaze from burning green wood. A brush cannot remove glazed creosote. It’s a hard, tar-like coating that requires chemical treatment or rotary removal. In wood stoves around Uniondale, where people heat with whatever they’ve got, this is more common than many homeowners realize.
- Cracked clay tile liners at the smoke chamber. Uniondale’s original 4-inch clay tile liners were sized for high-heat oil combustion. Decades of gas exhaust and thermal cycling leave them cracked and offset. A sweep that doesn’t include a camera check will miss this entirely.

FAQs - Chimney Cleaning & Sweep in Uniondale
Because Uniondale’s Cape Cods were built for oil-fired boilers, and almost all of them were converted to natural gas in the 1980s and 1990s. Those conversions often included unpermitted flex-liner patches that don’t meet current Nassau County code. Even if you only burn a fire on holidays, the flue is still original 60 to 75-year-old clay tile that may be cracked or offset. A Level 2 inspection with camera documentation tells us what we’re working with before a brush ever goes up. Call (516) 963-1068 and we’ll explain what your specific chimney needs.
Yes, and this is something Wendell talks about constantly. A brush removes first-degree creosote and soot. It does not remove third-degree creosote glaze, and it does not tell you whether the clay tile liner behind the buildup is cracked. In Uniondale, where coastal air eats mortar and old gas conversions left chimneys oversized, a brush-only sweep can leave the flue looking clean while it’s actually not safe. We run a camera on every sweep. It costs a little more and it’s the only honest way to know.
The national guideline is once a year, but in Uniondale that’s often not often enough. If you’re burning unseasoned wood, or burning daily through the winter in a tight ranch, you may need a sweep every 40 to 50 burns. The creosote loading is heavier, the flue temps run lower, and the old clay liners hold onto the residue. Wendell will tell you after the first sweep what your interval should be, based on what he pulls out and what the camera shows. For an exact assessment, call (516) 963-1068.
The unpermitted flex-liner patch from the 1980s or 1990s gas conversion. Nassau County now requires a permitted, properly sized stainless liner, and when a home inspector flags an old patch, the closing stalls until a Level 2 inspection documents it and the liner is corrected. We do those inspections regularly for Uniondale homeowners who are selling, and for buyers who want the truth before they sign. The fix is often a correctly sized DuraFlex system, and we’ll show you the camera footage to prove what’s actually needed rather than selling you what isn’t.
Yes, if they’re installed correctly and maintained. Uniondale’s freeze-thaw cycles pull moisture into any crack in the crown, and that water expands and contracts all winter, widening the damage every year. A proper concrete crown with an overhang, plus a stainless cap from Copperfield or Gelco, keeps rain and snow out of the flue and off the smoke shelf. It won’t fix an already-cracked liner, but it will stop the water intrusion that makes everything worse. Call (516) 963-1068 if you want us to look at your crown before next winter.
