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 Services in Smithtown, NY
If your Smithtown home runs on an oil-fired boiler, your chimney has spent decades exhausting acidic, sulfur-heavy soot through brick that was laid during the Johnson administration. That’s not a metaphor. The majority of chimney work we do in Smithtown isn’t the classic wood-stove sweep people imagine when they call. It’s flue inspection, lining assessment, and cleaning built around the oil-to-gas conversions now moving through Suffolk County at a steady clip. Wendell Pike and his crew at Top Hat Chimney have been in and out of these same mid-century chimneys since 1999, and we answer the phone when you call: (516) 968-5380.

Why Smithtown Homeowners Choose Top Hat Chimney
Ask anyone on your street. That’s the whole pitch. Wendell puts his name on every job, publishes his license number, and still runs into customers on Saturday at the King Kullen in Kings Park or the bagel shop off Main Street in Nesconset. A national chain sends a different crew every season with a different price sheet. Wendell shows up himself, most days, and the guy who sweeps your flue is the same guy who answers when you call back with a question in November.
We’ve worked the same Smithtown subdivisions long enough to know the home builder quirks behind the walls. In the ranch and split-level tracts of Kings Park, we see the same lime-mortar brick chases with the same failing parging, house after house. Customers tend to find us through a neighbor whose oil-to-gas conversion we handled the previous spring, or whose real-estate closing hung on the chimney inspection we got through. The 90-Day Done Right Promise is in writing on every job. If something’s not right, one call brings Wendell back, no argument, no invoice. And a live person answers the phone here twenty-four hours a day, seven days a week. No call center. No voicemail box that eats your message until Tuesday.
Chimney Cleaning Services We Offer in Smithtown
Chimney Cleaning & Sweep
A proper sweep in Smithtown means more than running a brush up and down. We clean the entire flue path, from the boiler or fireplace throat all the way to the cap, and we inspect for the acidic soot damage and spalled brick that oil exhaust leaves behind over decades. Every cleaning includes camera footage of what we found.

Chimney Repair
Fifty-year-old common brick and lime mortar don’t age quietly. We rebuild crowns, repoint brick, replace rusted dampers, and fix flashing failures caused by the roughly one hundred freeze-thaw cycles Smithtown endures each year. If it’s masonry work, Wendell will tell you straight whether it needs doing now or can wait three seasons.

Fireplace Services
Not every Smithtown chimney vents a boiler. Many of these mid-century homes have a decorative fireplace sharing a chase with the oil flue, and that arrangement causes drafting issues we see over and over in the same subdivisions. We service fireboxes, dampers, gas logs, and make sure the fireplace side of your chimney is safe to use if you actually light a fire.

Chimney Cap & Crown
Salt-laden air from Long Island Sound sits just a few miles north of Smithtown, and it eats metal caps and mortar crowns faster than homeowners expect. We install stainless caps sized to your flue, pour and seal crowns properly, and stop the water intrusion that turns a three-hundred-dollar repair into a three-thousand-dollar one.

Chimney Liner & Rebuild
This is the big one in Smithtown. The original builder in many Kings Park and Nesconset homes ran the oil-boiler exhaust and the fireplace flue through the same unlined brick chase with no tile liner in either channel. That was code-deficient even in 1965, went uninspected for decades, and now has to be corrected with full stainless relining before a real-estate transaction can close. We install DuraFlex and HeatShield systems rated for oil exhaust, gas, and wood, and we rebuild chases that have reached the end of their useful life.

Why Smithtown’s Climate & Housing Affect Chimney Cleaning
Smithtown sits close enough to Long Island Sound that salt-laden air works on your chimney year-round. Mortar joints soften faster than they would in, say, Brentwood or Huntington Station, which sit farther from the water. Metal dampers and caps corrode quickly, and rust-stained brick below the crown is a common sight from Old Northport Road down to Jericho Turnpike.
But the bigger factor for this town’s chimneys is the housing stock itself. Most of Smithtown was built between roughly 1955 and 1978. Those houses went up fast, and the builders used standard common brick with lime-based mortar and, in far too many cases, no tile liner at all in the boiler flue. Fifty-plus years of acidic oil exhaust later, the parging inside those flues is crumbling, the crowns are cracked, and the brick face is spalling. Add in about one hundred freeze-thaw cycles per year, and a chimney that looked fine in August can be shedding brick by March. That’s not scare talk. It’s what we see every week in Kings Park and Nesconset alike.

FAQs About Chimney Cleaning in Smithtown
A standard sweep and inspection in Smithtown runs $185 to $285 for most homes, with oil-boiler flues on the lower end and larger or harder-to-access fireplaces on the higher end. If we’re doing a real-estate inspection with a camera and written report, that typically runs $150 to $250 and often gets bundled into the sweep price. Call (516) 968-5380 for an exact quote before we come out, and know that the number Wendell gives you on the phone is the number on the invoice.
Once a year, burn or no burn. Chimneys break in the off-season too, and an oil-boiler flue that’s pushing acidic sulfur soot can develop a blocked or deteriorated liner without you ever seeing a single symptom until carbon monoxide backs up into the house. A yearly sweep and inspection catches that early, when it’s a three-hundred-dollar brush job rather than a five-thousand-dollar reline. Wendell has walked enough Smithtown basements to tell you plainly when a chimney can go another year, and he’ll tell you when it can’t.
Freeze-thaw cycles and salt air are the two main culprits here. Smithtown sits within a few miles of Long Island Sound, and the salt-laden air softens lime mortar and corrodes metal components faster than inland Suffolk communities. Then winter comes, and the roughly one hundred freeze-thaw cycles each year wedge water into every micro-crack until the crown splits and brick faces spall. A chimney that never gets used still gets wet, still freezes, and still fails. That’s why the yearly inspection matters even when no fire has been lit in twenty years.
In a lot of cases, yes. Homes built during Smithtown’s 1955-to-1978 housing boom were often thrown up fast, and many builders ran the oil-boiler exhaust through a bare brick chase with no tile liner whatsoever. Some of those same houses have the boiler flue sharing a chase with a decorative fireplace flue, with minimal separation between the two. That arrangement was questionable in 1965 and fails modern inspection standards today. If you’re selling a home in Kings Park or Nesconset and the buyer’s inspector flags the chimney, the fix is a full stainless relining, and that’s a call we handle more than any other kind of chimney work in Smithtown these days.
For a wood-burning fireplace, creosote builds up in stages. First-degree creosote is a brush job. Third-degree is a glaze, catch it early, because a glaze is a chimney fire waiting on the first hot burn. For an oil-boiler flue, the risk is different: acidic soot eats away the parging, then the brick, and eventually you have a breach letting exhaust gases into the house. Either way, the repair bill grows exponentially the longer you wait. If it’s been more than a year, call (516) 968-5380 and have Wendell take a look. The camera footage and a plain-English verdict, every time, no exceptions.

What Smithtown Customers Say
"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"Converted our old wood burner to gas and took the time to talk me out of the fancier insert I had picked out because it would have been wrong for the size of the room."
- Duane Kittering"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."
