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.

AfterFast, Reliable Chimney Cleaning & Sweep Across Islip
Chimney cleaning in Islip typically costs $189-$329 for a standard sweep with a Level 1 inspection, and most jobs are completed in under two hours. If you live in Bay Shore, East Islip, Islip Terrace, or anywhere else in the town, our crew knows your streets, your housing stock, and the salt air that works on your chimney year round. Wendell Pike founded Top Hat Chimney in 1999, and the number he answers is (934) 935-3847. Call it and you’ll get a straight answer on price before a single tool comes off the truck.
Why Top Hat Chimney Is Islip’s Preferred Chimney Cleaning & Sweep Company
We’ve swept chimneys on streets running south to the bay for over 29 years, and the houses here have a particular character: cape cods and ranches with 50-to-70-year-old clay tile liners that were built for oil burners, not fireplaces. That matters because the corrosive soot from oil exhaust eats mortar joints and liners from the inside in a way that wood smoke does not. A national outfit that rotates crews through the area won’t spot the difference until the damage is already priced into an estimate you did not ask for. Wendell’s crew works Islip every week, and when he says a flue needs attention, he can show you the camera footage that proves it.
Our reputation in Islip is built on something simpler than marketing: the sweep who shows up at your door is the same person whose name is on the truck. We publish our license number, we answer the phone around the clock with a live person (often Wendell himself), and every job carries our 90-Day Done Right Promise in writing. If it isn’t done right, one call brings us back at no charge. You won’t get that from a franchise whose nearest call center is three states away.
When you call for a sweep in Islip, we schedule a real arrival window, not “sometime between 8 and 6.” If that window slips, we call you before it does. Ask anyone on your street. They’ll tell you the same thing: Top Hat shows up, quotes a fair number, and leaves the flue breathing the way it should.
Our Chimney Cleaning & Sweep Services in Islip
Every Chimney Cleaning & Sweep job we do in Islip starts with a conversation about what’s actually venting through the flue. In this town, that’s often an oil burner, not a fireplace. Here’s what we handle most often.
Level 1 Inspection
A Level 1 inspection is included with every sweep and covers the readily accessible portions of the chimney: the flue interior, the cap, the crown, and the firebox or appliance connection. In Islip’s attached housing, we pay particular attention to whether any part of the flue path runs adjacent to a neighboring unit’s chase. If it does, we note it, because that changes how we read the condition of the liner. Most Level 1 inspections in Islip run $129-$189 when bundled with a sweep.
Level 2 Inspection
A Level 2 inspection goes further: video camera scanning of the full flue length, from the appliance or firebox to the cap. This is the one we recommend most often in Islip, especially for attached homes, because it’s the only way to see cross-flue contamination from an adjacent property’s exhaust. It’s also required by most insurers after a chimney fire, a change in appliance type, or a property sale. In Islip, a Level 2 inspection typically runs $229-$349 depending on flue length and whether any shared chase is involved. The camera footage and a plain-English verdict come standard, every time, no exceptions.
Creosote Removal
First-degree creosote is a brush job. Third-degree is a glaze that can bond to the flue liner and require chemical treatment or mechanical removal. In Islip’s shared stacks, we’ve seen third-degree creosote form on a homeowner’s side of the flue even when their own fireplace was barely used, because the neighbor’s oil exhaust accelerated the glaze. Creosote removal in Islip is priced by flue length and degree of buildup, typically $150-$280 for standard first and second degree, with glazed third-degree running higher because of the extra labor and treatment.
Soot Removal
If your chimney vents an oil burner, the buildup inside is acidic sulfurous soot, not creosote. It’s corrosive, it’s sticky, and it attacks mortar joints from the inside. In Islip’s 1950s-to-1970s housing stock, that soot has often been accumulating for decades. Soot removal for oil flues in Islip runs $160-$260, and we’ll tell you plainly whether the liner beneath the soot is still sound or whether it’s time to talk about a reline. Nothing gets recommended without camera evidence you can see for yourself.

Trusted Brands We Service in Islip
When we install or repair components in Islip, we stock and service the brands that hold up here: Copperfield caps and dampers, DuraFlex stainless steel relining systems, and Famco vents and fans. The salt air off Great South Bay has a way of separating good metal from cheap metal in a single season, so we don’t put parts on a bayside chimney that we know won’t last. Because we keep common parts on the truck, most Islip jobs are completed in one visit, no waiting on a warehouse shipment.
Common Chimney Cleaning & Sweep Problems We See in Islip Homes
- Shared flue stacks in attached homes. Along bayside streets in Bay Shore and Oakdale, adjoining units often vent into the same masonry stack. A neighbor’s oil-burner exhaust can contaminate your flue liner and slow your draft even if your own system is dormant. We see this every week in the older attached stock along Montauk Highway.
- Rusted-out galvanized caps. Standard galvanized chimney caps, which hold up fine a dozen miles north in Smithtown, can rust through in as little as three to four years in Ocean Bay Park, Oakdale, or anywhere else the bay air reaches. Once the cap’s gone, nor’easter rain drives straight into the flue.
- Freeze-thaw spalling on aging brick crowns. The town’s South Shore exposure means wind-driven rain gets forced into crown cracks that inland chimneys never see. Through a Long Island winter, that water freezes and thaws, and the crown starts losing mortar in chunks. We catch this early on inspections, which is a lot cheaper than rebuilding the top of a stack.
- Acidic oil soot eating clay tile liners. Most Islip chimneys were built for oil-fired heating, and the corrosive condensate from that oil gradually erodes the interior of the clay tile liner. After 50 to 70 years, many of those liners are near the end. A sweep tells you where yours stands before it becomes a hazard.
Pricing for Chimney Cleaning & Sweep in Islip, NY
Here’s what you’ll actually pay in Islip, no phone-then-door switch. A standard chimney sweep with Level 1 inspection runs $189-$329 for a single flue. Add a Level 2 inspection with video camera scan and you’re looking at $229-$349 for the inspection alone, depending on flue length. Creosote removal is $150-$280 for typical buildup, and glazed third-degree creosote runs higher because of the treatment involved. Soot removal for oil-burner flues is $160-$260. If a fireplace and an oil burner share the same stack, expect the higher end of these ranges because both flues need attention. We give you a fixed price before work begins, and the number we quote is the number on the invoice. Seniors and veterans get 10% off, always. Call (934) 935-3847 for an exact quote. Estimates are free.

FAQs - Chimney Cleaning & Sweep in Islip
Yes, and we see it regularly. In attached homes where flues share a masonry stack, the exhaust from an adjacent unit’s oil burner can vent into your side of the stack, depositing acidic sulfurous soot and condensate on your flue liner. That contamination can block draft and degrade mortar joints even if your own fireplace or appliance hasn’t been used all season. A Level 2 inspection with camera scan in the shared chase is the way to confirm it, and it runs $229-$349 in Islip. Call (934) 935-3847 and we’ll put eyes on your flue before it becomes a bigger problem.
Salt air off Great South Bay is the difference. In bayside neighborhoods like Oakdale and East Islip, persistent onshore salt spray and high humidity corrode standard galvanized caps in as little as three to four years, while the same cap ten miles north in an inland Suffolk town might last a decade. Once the cap rusts through, nor’easter rain funnels straight into the flue and accelerates crown damage. We spec stainless steel or copper caps here from the start. It’s not an upsell; it’s the practical answer for this coastline. Call (934) 935-3847 for a cap assessment.
Yes, you do, and in some ways more than a wood-burning home does. Oil burners produce acidic sulfurous soot that corrodes clay tile liners and mortar from the inside, and in Islip’s post-WWII housing stock, most of those liners are 50 to 70 years old. Sweep once a year, burn or no burn. The cost runs $160-$260 for an oil-flue soot removal in Islip, which is a fraction of what a reline costs if the acid wins. Call (934) 935-3847 to schedule your annual sweep.
Third-degree creosote is a hardened, glazed layer that chemically bonds to the flue liner and can’t be removed with a standard brush. In a shared Islip stack, the heat and exhaust from a neighbor’s appliance can accelerate that glaze formation on your side of the flue. Left alone, it becomes a chimney fire hazard and constricts draft. Removal typically requires chemical treatment or mechanical rotary tools, and in Islip it runs higher than standard creosote removal because of the labor. Every year you skip the sweep makes it harder to remove. Call (934) 935-3847 to check what degree you’re dealing with.
Nor’easters tracking through Fire Island Inlet deliver wind-driven rain at pressure that inland chimneys never experience, and that water gets forced into crown cracks that would stay dry miles north. So when we inspect a crown in Oakdale or East Islip, we look for hairline fractures that may be invisible in dry weather but open up under wind load. We also look for salt staining on the masonry as a telltale of how much spray has been hitting it. That’s what tells us whether a crown needs sealing now or can wait another season. Call (934) 935-3847 for a crown inspection from a crew that understands this stretch of the bay.
