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, NY | Hearthstone Chimney Co.
Staten Island Chimney Cleaning & Sweep for DuraFlex systems typically runs $180-$340 for a standard sweep with Level 2 camera inspection, and most appointments are completed in a single visit. What sets our DuraFlex work apart on Staten Island is the salt-air inspection protocol we’ve developed after years of finding harbor-driven corrosion on cap rims and top plates that inland sweeps rarely encounter. If your DuraFlex liner is sound, we’ll say so. If it isn’t, you’ll hear that too. Call (516) 613-3035 to book - a live person answers, day or night.
Why Staten Island Residents Choose Us for DuraFlex Service
We’ve been cleaning and inspecting DuraFlex stainless liners, caps, and top-plate assemblies across Staten Island for well over a decade. Russell Haines, our owner, started in this trade at Los Angeles Trade-Technical College before following work east and building Hearthstone Chimney Co. into a company that’s now served local communities for over 42 years. He and our crew know the difference between a DuraFlex 316L kit that’s weathering normally and one that’s pitting from salt air off the Kill Van Kull.
We’re not affiliated with, authorized by, or sponsored by DuraFlex. We’re an independent service company that stocks genuine DuraFlex top plates, cap adapters, and fasteners when available, and matches them with high-grade stainless aftermarket clamps and flashing where OEM supply is delayed. Our technicians are background-checked and uniformed, and we back every job with the 90-Day Done Right Promise in writing - no paperwork, no arguing. Photos you can see, a plain-English verdict. That’s the Keystone Standard.
Common DuraFlex Chimney Cleaning Problems We Solve in Staten Island
- Salt-air pitting on stainless liner walls and cap hardware. Staten Island’s position encircled by New York Harbor, the Kill Van Kull, and the Arthur Kill means salt-laden air hits chimney tops harder than anywhere else in the five boroughs. We regularly find surface corrosion on DuraFlex cap rims and top-plate bolts that would take fifteen years to develop inland. Our protocol: moisture meter and camera check on every sweep.
- Water intrusion at top plate or cap adapter from post-Sandy rebuilds. After Hurricane Sandy, general contractors across Midland Beach, New Dorp Beach, and Oakwood Beach installed DuraFlex components in 2013-2015 with mismatched flashing or chase-sealed adapters instead of proper top-plate seals. Salt air plus freeze-thaw cycles open these gaps fast. We find rust staining and creosote breakdown below the cap on chimneys that look new from the street.
- Damper and firebox component corrosion at liner tie-ins. In coastal-adjacent Staten Island homes, DuraFlex liners terminate into older cast-iron dampers that have already spalled from salt exposure. The interface corrodes faster than either component alone. We inspect this junction with a camera and document what we find - sometimes it’s cleaning and a new damper plate, sometimes it’s just creosote removal and reassurance.
- Liner joint separation or screw pull-through after freeze-thaw. Staten Island’s northeast winters cycle hard on salt-compromised masonry. The DuraFlex flexible section expands and contracts, but the brick around it doesn’t cooperate. We’ve pulled separated joints in Tottenville and Great Kills where the masonry itself had loosened, not the liner. The fix is re-anchoring and often crown waterproofing, not always full relining.
- Creosote glazing accelerated by moisture infiltration. When a DuraFlex cap leaks, creosote absorbs water and hardens into a glazed layer that’s tougher to remove. Staten Island’s humid harbor summers make this worse. We use professional-grade mechanical brushing and, when needed, chemical treatment to break it down without damaging the stainless wall.
DuraFlex Service in Staten Island: What Local Conditions Mean for Your Equipment
Staten Island is the only NYC borough where single-family homeownership dominates, giving it the highest concentration of active wood-burning fireplaces per capita in the five boroughs by a wide margin. That density of use, combined with harbor exposure, creates a maintenance profile no other borough matches. On a recent Midland Beach call, our tech found a DuraFlex stainless liner installed during a 2014 post-Sandy rebuild where the cap adapter had been flashed into the chase instead of sealed to the top plate; salt air and freeze-thaw had already pitted the cap rim and rust-stained the crown. We pulled the cap, cleaned the liner, replaced the cap adapter and gasket, waterproofed the crown, and left the liner in service - Chimney Repair in Staten Island that kept the homeowner from paying for a full reline.
This is why we bring a moisture meter on every South Shore call. A “young” chimney from 2013-2015 can hide active water infiltration behind clean brickwork. DuraFlex sales & service through Hearthstone means component-level diagnosis, not guesswork.

FAQs - DuraFlex Chimney Cleaning in Staten Island
Yes, typically by 30-50% compared to inland installations. Salt-laden harbor air accelerates pitting on stainless surfaces and corrodes cap hardware faster than DuraFlex’s own specs anticipate for standard environments. We check cap rims, top-plate bolts, and liner walls with a moisture meter on every Staten Island sweep - a step that rarely turns up active corrosion in Queens or the Bronx. If your cap is pitted but the liner wall is sound, we replace the cap and keep the liner. Call (516) 613-3035 to schedule - estimates are free.
Because 2013-2015 rebuilds by general contractors, not chimney specialists, frequently used mismatched DuraFlex components or improper flashing that creates hidden water paths. A Level 2 inspection with camera and moisture meter reveals cap-adapter gaps, crown saturation, and liner joint conditions that a visual check from the roof or hearth misses. We document everything with photos you can see and a plain-English verdict. Call (516) 613-3035 to book - the inspection itself is included in our standard sweep pricing.
Often, yes. If the flexible liner wall retains its full thickness and the joints are intact, we pull the damaged cap, clean the flue, install a new DuraFlex or compatible cap adapter with proper gasket and flashing, and waterproof the crown. We’ve saved Staten Island homeowners full relining costs dozens of times this way. The only honest way to know is a camera inspection. Call (516) 613-3035 for a free evaluation.
Spring through early fall. Beat the burning-season rush, and you’ll have time to address any salt-air corrosion or post-Sandy flashing issues before the first freeze-thaw cycle hits. That said, we sweep and inspect year-round - if you’re smelling damp creosote or seeing rust stains, don’t wait for the calendar. Call (516) 613-3035 and we’ll get you scheduled.
Usually, yes. St. George, New Brighton, and Stapleton are full of unlined or clay-tile-lined brick chimneys from the 1880s-1920s that need modern protection. DuraFlex 316L stainless kits, properly sized and insulated, slide into these tall, often offset flues where rigid liners won’t fit. We size carefully - oversizing reduces draft, undersizing traps smoke - and we always inspect with a camera first to map the flue’s true condition. Multi-flue jobs run higher due to scaffolding and complexity, but the liner itself is proven in these chimneys. Call (516) 613-3035 for a specific assessment.
