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 | Flint Chimney Sweep
Flint Chimney Sweep provides independent DuraFlex chimney cleaning and Staten Island Chimney Sweep service across the borough. We are not manufacturer-affiliated or authorized by DuraFlex, which means our inspection reports tell you what your liner actually needs, not what a factory rep wants sold. What makes our DuraFlex work here different is simple: we know how this borough’s salt air, high water table, and clay soil attack stainless steel liners in ways you won’t see in a DuraFlex manual. Call (830) 251-4560 for a written estimate before any work begins.
Why Staten Island Residents Choose Us for DuraFlex Service
We’ve serviced DuraFlex stainless steel chimney liners and venting components across Staten Island for over a decade. That matters because DuraFlex systems fail differently here than they do inland. Salt-laden air off the Kill Van Kull and Raritan Bay accelerates corrosion pitting, while the borough’s clay-heavy soil and freeze-thaw cycles shift chimney structures and kink flexible liners. Our techs know what those failure patterns look like up close.
Hank Delano, our owner, learned the trade through the building maintenance and construction technology program at Los Angeles Trade-Technical College, then put in years of hands-on chimney work before starting Flint Chimney Sweep. He’s known for straightforward inspections: he’ll tell you exactly what your firebox and flue liner look like and what, if anything, needs doing, without padding the invoice. Every Staten Island call is dispatched with a background-checked, uniformed technician. If you’re unsure whether your DuraFlex liner is safe, our standard answer applies: tell me what you’re seeing, I’ll tell you what it means.
We’re part of the Garrison Partners family of independently owned chimney service companies, founded in 2002. That means we operate under The Garrison Standard: every job gets a written price before work starts, and every repair carries the 365-Day Done Right Promise, a written guarantee valid for one full year from the service date. If a covered repair fails within that period, we return at no charge. No argument, no invoice on the second visit.
Common DuraFlex Chimney Cleaning Problems We Solve in Staten Island
- Salt-air corrosion on liner crowns. The top 2 to 3 feet of a DuraFlex liner takes the most punishment in Staten Island. Condensate and sea spray collect there, and over time the stainless develops pitting that weakens the metal. During a cleaning we inspect that upper section closely. Surface corrosion gets cleaned and repointed. Perforation means replacement, not patching.
- Creosote buildup at corrugated ridges. Improperly sized DuraFlex inserts, especially on wood-burning fireplaces in older Staten Island homes, trap creosote in the liner’s corrugations. That glazed, tar-like layer is a chimney fire waiting to happen. Our rotary sweeps remove it from the ridges without damaging the stainless.
- Kinked or crushed flexible liners. Staten Island’s clay soil shifts with every freeze-thaw cycle. In older masonry chimneys, that movement transfers to the liner and can kink or crush it. A kink restricts draft and creates a creosote trap. We find these during Level 2 inspections and replace the damaged section rather than trying to straighten it.
- Rust-through on caps and top plates. DuraFlex caps and top plates take direct salt exposure year-round. Once they rust through, rainwater gets inside the chase and degrades the liner from the top down. We replace caps with OEM DuraFlex components when available, or quality aftermarket stainless when the OEM part is backordered.
- Corrosion at the liner base from crawl-space moisture. This is the Staten Island pattern most chimney companies miss. We’ll get into it in detail below, but the short version is: damp air wicks up through masonry and attacks the bottom of the liner from the outside in.
DuraFlex Service in Staten Island: What Local Conditions Mean for Your Equipment
Staten Island’s North Shore has a high water table, and many homes there were built on former wetlands. Walk into a crawl space under a 1940s colonial in Port Richmond or West Brighton and you’ll often find the chimney base and cleanout door sitting in damp, musty air. That constant moisture isn’t just a basement problem. It wicks up through the masonry and corrodes the bottom section of a DuraFlex liner from the outside in. We see liner bases eaten away even when the upper flue looks perfectly fine. This is a pattern we rarely encounter in drier inland boroughs, and it’s one reason a standard visual check from the roof can miss serious damage. Our techs inspect the full liner run, including the section you can’t see from outside, before we sign off on any cleaning.
In West Brighton, we serviced a 1950s colonial whose DuraFlex Stainless Steel Liner showed a kink about four feet down, caused by shifting clay soil and repeated freeze-thaw. Our tech used a rotary sweep to remove glazed creosote from the corrugated ridges, then replaced the kinked section and installed a new multi-flue cap to stop further water intrusion. The homeowner passed a Level 2 inspection afterward and scheduled annual sweeps to prevent future damage.
DuraFlex Models & Products We Service in Staten Island
We clean, inspect, and repair the full DuraFlex lineup, including the DuraFlex Stainless Steel Liner, DuraFlex SW (Single-Wall) Relining Kit, DuraFlex Pro Flexible Liner, and DuraFlex Insulated Liner. Each model has different corrugation patterns and clearance requirements, which affects how aggressively we can sweep. The SW kit, for example, has a lighter wall than the Pro or Insulated lines, so we adjust our rotary head speed accordingly. For parts, we use OEM DuraFlex components whenever they’re available to keep the UL listing intact, but we’ll switch to quality aftermarket stainless when the OEM part is on backorder and you need the job done this season. If you’re shopping for a new system or a liner replacement, see our full DuraFlex sales & service page for details on what we stock and what we special-order.
DuraFlex Service Pricing in Staten Island
A standard DuraFlex chimney cleaning in Staten Island typically runs $189 to $325, depending on liner length, creosote stage, and whether the fireplace insert needs to be pulled for access. A Level 2 camera inspection runs $149 to $299. DuraFlex cap replacement runs $245 to $595 installed, including the new cap. Full liner replacement varies widely based on the liner model, chimney height, and access; expect $2,500 to $6,500 for most Staten Island homes. If a liner shows only surface corrosion, we clean and repoint rather than selling you a replacement. If it’s perforated or kinked, we tell you plainly and recommend full replacement. Every estimate is written and free. Call (830) 251-4560 for an exact quote.

FAQs – DuraFlex Chimney Cleaning in Staten Island
Yes. DuraFlex liners are stainless, but stainless is corrosion-resistant, not corrosion-proof. The top 2 to 3 feet of a liner, where condensate and sea spray collect, develops pitting over years of exposure to salt-laden air from the Kill Van Kull and Raritan Bay. We see it on nearly every liner older than 8 to 10 years in the borough. Surface pitting gets cleaned and monitored. Full perforation means replacement. Call (830) 251-4560 and we’ll camera-inspect your liner and show you exactly what we’re seeing.
You don’t, without looking. A ten-year-old DuraFlex liner in Staten Island has been through roughly 365 freeze-thaw cycles and ten years of salt exposure, so it’s at the age where we start watching for pitting, kinks, and base corrosion. We run a camera down the full liner run during a Level 2 inspection. If the liner is sound and the creosote is Stage 1 or 2, a cleaning is all you need. If the camera shows perforation, a kink, or corrosion at the base, we’ll show you the footage and recommend replacement. Call (830) 251-4560 for a free estimate on either service.
It depends on the insert and the liner placement. Many wood-burning inserts allow bottom-up access through the firebox, and we can sweep the liner without pulling the unit. Direct-vent gas inserts channel exhaust through a smaller pellet vent, which sometimes requires removing the insert front to access properly. We assess access during the inspection and tell you what’s needed before we start. The cleaning quote you approve is the price you pay, whether the insert stays put or has to come out.
Salt. The cap sits at the highest point of the chimney, fully exposed to salt spray off the water. Once the factory finish is compromised, rust sets in and spreads. We replace rusted DuraFlex caps with OEM components when available, or aftermarket stainless when the OEM cap is backordered. The new cap gets the same salt exposure, but a proper stainless cap will still outlast the galvanized steel material some contractors substitute. We’ll give you a written price for the cap and the labor before any work starts.
We use OEM DuraFlex components whenever they’re available for liners, caps, and top plates. OEM parts preserve the system’s UL listing and the intended fit. When a DuraFlex part is backordered and you don’t want to wait out the season, we’ll recommend a quality aftermarket stainless replacement and tell you that’s what we’re doing before we install it. We’re an independent service provider, not a DuraFlex dealer, so the recommendation is based on what’s right for your chimney, not what clears our inventory.
