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.

AfterDuraFlex Chimney Cleaning in Staten Island, CA | Alcott Chimney Sweep
We’re Alcott Chimney Sweep, and we provide independent DuraFlex chimney cleaning, Staten Island Chimney Inspection, and liner service across Staten Island. What makes our DuraFlex work here different comes down to one thing: Staten Island’s salt air eats the termination hardware on these liners faster than almost anywhere else in the metro, and we scope every flue with that specific failure in mind. Call (336) 863-3889 and we’ll tell you exactly what we’re looking for.
We work on DuraFlex 316L liners, Pro pre-insulated wraps, and tee systems in more Staten Island homes than any other brand. We’re not a DuraFlex dealer or authorized service center. We’re an independent chimney company that knows the product line well enough to catch what other sweeps miss. That distinction matters when you’re deciding who to let onto your roof.
Why Staten Island Residents Choose Us for DuraFlex Service
Ruben Castellano grew up in Boyle Heights and spent nearly twenty years working chimneys across Los Angeles before bringing Alcott’s approach here. He picked up heating and ventilation fundamentals through the HVAC and building trades program at East Los Angeles College, then apprenticed under a veteran sweep who taught him the difference between a flue that looks clean and one that actually is. Our DuraFlex familiarity grew from there, because coastal masonry chimneys are exactly where stainless flexible relining earns its keep.
For Staten Island homeowners, that means you’re getting a crew that has completed hundreds of DuraFlex liner installs across North and South Shore housing stock. We stock DuraFlex sales & service parts locally for faster turnaround: OEM cap adapters, top plates, and tee snouts. When you call, a live person answers, and the tech who shows up has been background-checked and identity-verified under the Threshold Standard. You’ll see their name and photo before they arrive.
Common DuraFlex Chimney Cleaning Problems We Solve in Staten Island
- Salt-air corrosion at the cap adapter and top plate. Staten Island’s year-round marine environment, fed by the Kill Van Kull and Raritan Bay, pits 316L stainless at the crown faster than inland NYC. We see white rust and pitting that cracks the liner’s top seal, and that’s a fix we handle every week.
- Insulation wrap separation inside the flue. The foil facing on DuraFlex pre-insulated wrap can pull loose and collect soot. The result is hidden creosote pockets behind the wrap that a basic visual sweep won’t show. We camera-scan for exactly this on every cleaning.
- Tee snout corrosion in the thimble. On South Shore chimneys rebuilt after Sandy, the DuraFlex tee often sits against damp, unsealed masonry. The branch connection corrodes and can leak exhaust into the wall cavity. We catch it before it becomes a flue fire.
- Improperly seated liner at the damper area. Post-Sandy owner-rebuilt chimneys routinely have DuraFlex liners shoved through damaged damper frames without a transition plate. That gap lets creosote drip onto the smoke shelf. We find this on Great Kills and Oakwood routes more than anywhere else we work.
- No waterproofing at the crown after liner install. A DuraFlex liner re-install that skips crown coating will fail again in three to five years on Staten Island. The salt air doesn’t pause because the liner is new. We waterproof every crown we touch.
Tell me what you’re seeing and I’ll tell you what it actually means. That’s the starting point for every DuraFlex call we run on Staten Island.
DuraFlex Service in Staten Island: What Local Conditions Mean for Your Equipment
Here’s the thing about Staten Island that doesn’t show up on most chimney company websites. This borough has the highest concentration of wood-burning fireplaces and masonry chimneys per capita in all five boroughs, yet it’s also an island fully surrounded by tidal waterways. The Kill Van Kull to the north, Arthur Kill to the west, Raritan Bay to the south. That combination means thousands of exposed masonry chimneys sitting in salt air every single day, and mortar joints and metal flashing corrode at rates you simply don’t see in Duraflex service in Brooklyn or the Bronx.
Post-Sandy rebuilds made it worse. South Shore neighborhoods like Midland Beach, New Dorp Beach, and Oakwood Beach saw hundreds of chimneys patched or owner-rebuilt without proper NYC-code-compliant stainless liner systems. A DuraFlex liner with a suspiciously new cap but original smoke-stained flue tiles above it is a red flag we see constantly on Staten Island, and almost never inland. That’s why we scope the entire flue, not just the firebox, on every DuraFlex cleaning here. If a liner was installed after 2012 in a South Shore home, we assume it hasn’t been inspected properly until we prove otherwise.
DuraFlex Models & Products We Service in Staten Island
We service the full DuraFlex residential line: 316L stainless steel flexible liner kits, Pro stainless flexible liners with pre-insulated wrap, Insulated Tee kits for wood-burning fireplace inserts, and stainless steel chimney caps. On parts, we stock genuine DuraFlex OEM cap adapters, top plates, and tee snouts because coastal corrosion means the warranty on those components actually matters here. For standard stainless hose clamps and masonry anchors, we use UL-listed aftermarket equivalents that hold up the same in salt air. We’ll always tell you plainly when a failed liner can be re-terminated and re-capped versus when the whole run needs replacing. On pre-1970 North Shore brick chimneys, the original terracotta flue tile is often the weak link, not the liner itself. We won’t sell you a liner replacement when the tile joints are the actual problem.
We also handle Level 2 inspections, cap installation, and chimney waterproofing as part of every DuraFlex service call where conditions call for it. That combination is what keeps a liner intact through Staten Island weather cycles, and it’s the same approach we bring to every Staten Island service area job we take.
DuraFlex Service Pricing in Staten Island
A standard Staten Island Chimney Sweep for DuraFlex typically runs $220 to $380, and that covers the sweep, a visual inspection of the liner and termination, and a written summary of what we found. If we’re adding a Level 2 camera inspection, plan for roughly $175 to $300 on top. Cap adapter replacement on a corroded top plate usually lands between $150 and $450 depending on whether the crown needs sealing at the same time. Full liner replacement runs anywhere from $2,200 to $5,500 on Staten Island homes, with South Shore post-Sandy rebuilds often on the higher end because the surrounding masonry needs work too.
You get a written price before any work starts. Always. No digging into the job and discovering a surprise line item. If you want an exact number for your chimney, call (336) 863-3889. Estimates are free, and we’ll tell you honestly what can wait and what can’t.

FAQs – DuraFlex Chimney Cleaning in Staten Island
Yes, and it’s measurable. The 316L stainless itself holds up well, but the cap adapter and top plate connection sits directly exposed to marine air, and we see pitting and white rust at that joint far earlier on Staten Island than in inland boroughs. You can add years to a liner by waterproofing the crown and replacing corroded termination hardware before it cracks the top seal. Call (336) 863-3889 and we’ll assess what’s happening at your crown during a standard cleaning.
You need one more than anyone on the island. We routinely scope Great Kills and Oakwood chimneys where a post-Sandy ‘repair’ meant shoving a liner through a damaged damper frame without transition plates or proper termination. Those flues pass a casual visual but fail a camera scan. Book a Level 2 inspection. The cost is small compared to what a leaking liner does inside a wall cavity over five years.
Technically yes, but we won’t do it without addressing the crown. A new cap sitting on a cracked crown just creates a different leak path. We waterproof or reseal the crown, install the OEM DuraFlex cap adapter, and run a camera scan to confirm the liner is seated correctly. Our 365-Day Done Right Promise covers that repair in writing. If it fails within a year, the second visit is free.
Most open masonry fireplaces in Annadale-era Colonials take a 6-inch or 7-inch liner, but the right answer depends on your flue tile dimensions, fireplace opening, and what the original builder installed in the 1970s or 1980s. We measure all of it, not just the firebox, before quoting a liner. A liner that’s too small for your flue can restrict draft and push smoke back into the room. Call (336) 863-3889 and we’ll size it correctly the first time.
Every year if you burn wood regularly, and every two years at minimum. Salt air builds up on the cap screens and top terminations, and the pre-insulated wrap can trap soot behind loose foil facing. Staten Island’s coastal moisture also makes creosote stickier and more corrosive than dry inland conditions. An annual sweep and visual inspection is cheaper than a liner replacement, and both are cheaper than a chimney fire - something we see far less often with proper Duraflex repair in Manhattan conditions.
