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.

Chimney cleaning in Uniondale, NY typically costs between $189 and $329 for a standard sweep, with most jobs completed in about an hour.

That changes what a “routine” cleaning actually involves. Call us at (516) 963-1068 and Wendell or one of his crew will give you a straight answer before a single tool comes off the truck.

Why Uniondale Homeowners Choose Top Hat Chimney
Uniondale isn’t a town full of new construction. The overwhelming majority of homes here went up between 1947 and 1965, and most still have their original masonry chimneys. When we show up in Whitney Gardens or over near Hempstead Turnpike, we already know what we’re likely to find before the ladder comes off the truck: oversized clay tile flues originally sized for oil heat, now venting natural gas after a conversion done decades ago. That’s not a guess. That’s just what’s here.
Homeowners keep calling us for the same reasons. The price we quote on the phone is the price on the invoice. Every job carries the 90-Day Done Right Promise in writing, and if something isn’t right, one call brings Wendell back. All our sweep technicians are background-checked and arrive in uniform with a real arrival window. We don’t send a stranger. We send someone whose name you’ll see again at the hardware store on Saturday.
Ask anyone on your street. In Uniondale, chimney work tends to get discussed over fences, because half the homes on any given block have the same original flue and the same water stains on the living room ceiling. Word gets around.
Chimney Cleaning Services We Offer in Uniondale
Chimney Cleaning & Sweep
A proper sweep in Uniondale means more than running a brush up the flue. Given the age and fuel-conversion history of these chimneys, it means checking the clay tile for cracks while we’re in there, because the acids from gas combustion have been eating at clay liners that were never built for low-temperature, high-moisture exhaust. The brush work removes the creosote and soot; the camera work shows you what’s left behind.

Chimney Repair
Uniondale’s coastal air, sitting roughly eight miles north of the South Shore, means mortar joints and brick faces here break down faster than they do inland. Salt spray, nor’easter rain, and hard freeze-thaw cycles work on the outside of the stack while the flue deals with its own chemistry. We repair masonry, repoint joints, rebuild shoulders, and fix the water damage before it becomes a beam problem in your ceiling.

Fireplace Services
Some Uniondale homes never had a fireplace at all. The chimney was built for a furnace in the basement, and the fireplace is either decorative or was added later. We service what’s actually there: dampers, fireboxes, hearths, and the gas log sets that many homeowners switched to when wood burning became more trouble than it was worth. Your flue doesn’t care how the fire looks. It cares how it breathes.

Chimney Cap & Crown
The crown is the concrete slab at the top of the chimney, and in Uniondale it’s often the first thing to fail. Decades of exposure to salt air and winter freeze-thaw cycles crack it open, and once water gets under the crown it travels down through the masonry and into your attic. We install stainless caps, seal crowns, and replace them when they’ve gone past patching.
Chimney Liner & Rebuild
This is the conversation we have at more Uniondale doors than any other. When your home was converted from oil to gas, the existing clay liner became the wrong tool for the job. Many homeowners had flex-liner patches installed in the 80s and 90s, often without permits. Current Nassau County code requires a properly sized, permitted stainless liner. We install DuraFlex liners sized to the appliance that’s actually connected to your flue, and we’ll show you the before-and-after camera footage. When a liner job comes with HeatShield resurfacing as an alternative, we’ll tell you when that’s a legitimate option and when it isn’t.

Why Uniondale’s Climate & Housing Affect Chimney Cleaning
Uniondale’s residential core is almost entirely post-WWII Cape Cod and ranch homes built between roughly 1947 and 1965. These houses were framed for oil-fired boilers, and their chimneys were sized for that: short, hot, high-draft burns that pushed exhaust out fast. Then the 80s and 90s oil-to-gas conversion wave swept through Nassau County, and suddenly those oversized flues were venting gas. Gas burns cooler and wetter. The flue condenses. The condensate is slightly acidic, and it has been eating at the original clay tile liners for thirty-plus years now. That’s why relining is not a rare upsell in Uniondale. It’s the central conversation almost every sweep has at almost every door.
The climate adds its own pressure. Uniondale sits close enough to the Atlantic that salt-laden air accelerates mortar erosion and brick spalling, while winter freeze-thaw cycles force moisture deeper into already-compromised joints. The result is predictable: crown cracks, flashing leaks, and liners that were marginal to begin with failing a few years sooner than they would in, say, Garden City or West Hempstead. None of this makes your chimney dangerous automatically. But it does make regular inspection here more important than it is in communities with newer stock or less coastal exposure.

FAQs About Chimney Cleaning in Uniondale
A standard chimney sweep in Uniondale runs $189 to $329, including a basic safety inspection of the flue, firebox, damper, and cap. Homes with taller stacks, heavy creosote buildup, or never-swept liners may push toward the high end. The exact price depends on what we find when the camera goes in. Call (516) 963-1068 and we’ll give you a firm number before we schedule, not a “starting at” lure.
In Uniondale, a majority of chimneys we inspect still run their original 4-inch clay tile liners from the late 40s through mid 60s. If your home was converted from oil to gas, that liner is oversized for the appliance it now vents, and the acidic condensate from gas exhaust has likely been degrading it for decades. We don’t recommend replacement without showing you camera footage of the crack, offset, or spalling that justifies it. When the footage shows a solid liner, we say so and leave it alone. Nothing is recommended without evidence.
Once a year, burn or no burn. Chimneys break in the off-season too. Uniondale’s coastal moisture and freeze-thaw cycles mean even a dormant chimney is taking on water through its crown and mortar joints, and a yearly inspection catches that before it becomes a $4,000 rebuild. If you burn wood, annual sweeping is non-negotiable. If you’re gas-only, the sweep becomes more about inspection than creosote removal, but you still want eyes on that clay liner once a year.
Creosote accumulates inside the flue and can ignite, and a chimney fire runs hot enough to crack clay tile liners and send flames into the framing. Even without a fire, water intrusion through a cracked crown rots the masonry from inside, rusts the damper, and eventually stains your ceilings. In Uniondale, unpermitted flex-liner patches from the 80s and 90s are also sitting in a lot of flues right now, and you may not know until a home inspection flags it during a sale. One call to (516) 963-1068 gets you an honest look at what’s actually in your chimney.
Yes, and in this town it’s often the difference between a clean closing and a renegotiated price. Nassau County code now requires a properly sized, permitted stainless liner in converted chimneys, and we routinely uncover unpermitted flex-liner work from the 80s and 90s that must be disclosed and corrected before the home can close. We provide a written report with camera footage you can hand directly to the buyer’s agent or the town inspector. Call (516) 963-1068 to schedule an inspection; the report is yours to keep. Estimates are free.

What Uniondale Customers Say
"Wendell has swept our chimney every autumn for six years now. He knows the flue better than I know it and he tells me when it does not need doing, which is not something most trades will admit to."
- Eleanor Prescott"He repointed the crown and waterproofed the stack, and two winters on there is not a damp mark on the ceiling where there used to be one every February."
- Harold Vance"Gave me the photos from inside the flue on a memory stick along with the invoice. I have never had a trade hand me evidence before."
