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 Brooklyn, NY | Emberly Chimney Cleaners
We provide independent DuraFlex chimney cleaning and inspection across Brooklyn, and the one thing that sets our work apart here is simple: we know what happens to these liners inside attached rowhouses with shared flues and salt-laden air. Brooklyn’s housing stock is unlike almost anywhere else in the country, and DuraFlex liners behave differently inside a 120-year-old Bed-Stuy brownstone than they do in a detached suburban home. Call (980) 580-8641 for a written estimate before any work begins.
Why Brooklyn Residents Choose Us for DuraFlex Service
We work on DuraFlex liners inside Brooklyn’s 2-4 story attached brownstones every week. That hands-on exposure to the product’s real-world performance in shared flues and coastal air gives us a depth of knowledge you won’t get from a sales brochure or a manufacturer’s spec sheet. Our techs know which DuraFlex components hold up in a narrow Brooklyn chase and which ones fail early when a party wall shifts or a nor’easter drives water through a Brooklyn Chimney Cap & Crown crack.
Corrine Halstead, our owner, grew up in Inwood at the northern tip of Manhattan, where Duraflex in Manhattan and attached brownstones with ignored chimneys were everywhere. She studied building trades technology at Bronx Community College before spending years working through inspection and cleaning work across all five boroughs. She runs Emberly Chimney Cleaners the same way she works a job site: name what’s found, put the number on the table, move on. When we inspect a DuraFlex liner in Brooklyn, we show you the camera footage before any conversation about price begins.
We’re an independent DuraFlex service provider, which means we’re not manufacturer-affiliated or authorized. We recommend what the liner actually needs, not what a brand rep would like us to push. Our track record is simple: 38,000+ chimneys inspected and cleaned since 2009, every one with a written price before work started and a documented photo record when it was done.
Common DuraFlex Chimney Cleaning Problems We Solve in Brooklyn
- Unsealed abandoned coal-era flues lined with DuraFlex. In converted Brooklyn brownstones, the original coal flue was often repurposed to vent an oil or gas boiler, then abandoned when the building was renovated. Rain, soot, and debris fall behind the liner top and corrode the stainless from the outside in. We see this pattern constantly in Bed-Stuy and Crown Heights, where conversion waves have left flues unsealed at the crown for decades.
- Pitting and creasing in older DuraFlex Aluminum liners. High-output gas ranges in Brooklyn’s galley kitchens produce acidic condensate that eats at aluminum liner walls. When the liner was forced through an offset in a brownstone’s narrow chase, creases at the elbows become weak points. We find internal pitting at these bends regularly, and we’ll tell you plainly if the liner has life left or needs replacement.
- Salt-air oxidation at the roofline. Brooklyn is surrounded by salt water on three sides: Upper New York Bay, the East River, and the Atlantic at the southern shore. That salt-laden air accelerates surface oxidation on exposed DuraFlex liner tops and termination caps, especially where the stainless mesh spark arrestor meets the clamp ring. Inland markets don’t see this failure mode at anywhere near the same rate.
- Reverse-draft conditions in shared two-flue stacks. Bed-Stuy and Crown Heights rowhouses often carry two flues in a single stack: one serving a decorative fireplace, one venting a boiler. When both appliances run simultaneously, reverse draft pulls moisture and soot into a DuraFlex liner that wasn’t properly sealed at the throat. Cleaning alone won’t fix that; the seal has to be addressed.
- Neighboring party-wall flue collapse. Brooklyn’s 1880-1930 rowhouse stack density means that when we clean a DuraFlex liner in one apartment’s flue, we often find the neighboring party-wall flue has collapsed brick or an abandoned unlined passage right next to it. You don’t see that in detached suburban homes where each chimney stands alone.
BeforeAfterDuraFlex Service in Brooklyn: What Local Conditions Mean for Your Equipment
Here’s what makes Brooklyn genuinely different for DuraFlex owners, and it’s not something a generic liner page will tell you. The dominant housing type in this borough is the attached pre-1930 brownstone and brick rowhouse, which means most chimneys contain multiple shared flues in a single stack, often serving both a decorative fireplace and a gas or oil boiler below, with the stack shared across party walls. Decades of conversions, coal to oil to gas, have left countless Brooklyn flues unlined, incorrectly lined, or still active without the owner knowing it. A DuraFlex liner installed in one of these flues in, say, 2008 may have been sized for an oil burner that was ripped out in 2016. When we show up to clean, we’re not just brushing creosote out of a tube; we’re checking whether the liner still matches what’s actually venting through it. That mismatch, not the liner itself, is the silent problem in this borough. Add Brooklyn’s salt-laden air accelerating oxidation at the roofline, and you have a set of conditions that don’t exist in neighboring suburban markets like Nassau or Westchester.
DuraFlex Models & Products We Service in Brooklyn
We stock and service the full DuraFlex product family: DuraFlex 316L (round and oval, 4″ through 8″), DuraFlex Pro with ProGard antimicrobial protection, DuraFlex SW (short wrap, zero-clearance wood stove liner), and DuraFlex Aluminum for mid-efficiency gas appliances. We use genuine DuraFlex components, couplers, tees, caps, and top plates, when replacing sections of an existing liner. Mismatched aftermarket parts create gaps and draft issues in narrow Brooklyn flues, so we don’t use them. If a liner is more than 60% rusted or separated at a seam, we recommend replacement rather than patching. If it’s intact but dirty, we clean and reseal it. We won’t upsell you a new liner because the old one looks scuffed.
DuraFlex Service Pricing in Brooklyn
DuraFlex chimney cleaning in Brooklyn typically runs $189 to $329 for a standard cleaning with camera inspection, depending on flue count and creosote class. A Level 2 inspection runs $249 to $449, and it’s worth it on any Brooklyn rowhouse with a conversion history. If we find cap or top plate corrosion from salt air during our Fireplace Services in Brooklyn, replacement runs $145 to $385, and we’ll show you the rust on camera before quoting it. The price drivers here are the age of the building, the number of flues in the stack, and how much creosote has built up in a liner that’s been ignored since the last gut renovation. We give you a written price, written scope, and written warranty before anyone starts, not after the tech is already in your home. That’s Clause 1 of the Haven Standard.

FAQs - DuraFlex Chimney Cleaning in Brooklyn
The rust you’re seeing is almost always salt-air oxidation at the exposed liner top or termination cap, not a product defect. Brooklyn’s position surrounded by salt water on three sides means surface corrosion forms on stainless components far faster than inland. We’ll confirm it with camera footage and tell you whether it’s cosmetic or structural. If it’s structural, we’ll quote the cap replacement before cleaning begins. Call (980) 580-8641 and we’ll schedule it.
Yes. We clean one flue at a time, sealing the adjacent flue at the throat before we brush. This prevents soot and creosote from dumping into your neighbor’s passage or pulling reverse draft into your own. Shared stacks are standard in Brooklyn rowhouses, so this isn’t a special procedure; it’s Monday for us. Call (980) 580-8641 and we’ll walk you through the process.
It can be. If the liner diameter no longer matches the venting requirements of a newer boiler, or if the liner has internal pitting from acidic condensate, you’ll get short cycling and poor draft. We’ll run a camera down and show you exactly what the flue walls look like. If the liner is intact but mismatched, we’ll tell you what it actually costs to correct it, and only if it needs correcting. Call (980) 580-8641 for a Level 2 inspection.
Yes, and the difference is the salt air plus shared flue conditions. We recommend a cap with a heavier-gauge stainless mesh and a sealed clamp ring on Brooklyn liners, because the Atlantic air eats standard mesh quickly and shared stacks create more condensation at the top. The right cap choice adds years to a liner in this borough, and the wrong one starts failing at the mesh-to-ring junction within a few winters. Call (980) 580-8641 and we’ll show you what’s on your liner now.
ProGard is an antimicrobial coating that resists the bacterial buildup that turns creosote into its most corrosive forms. In Park Slope’s pre-war brownstones, where fireplaces often sit idle for long stretches and then get heavy seasonal use, ProGard buys you margin against Class III creosote formation. Standard 316L is still a fine liner, but ProGard is worth the upcharge if you burn wood more than occasionally. We’ll give you a written quote for either option. Call (980) 580-8641.
