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.

Why Brooklyn Residents Choose Us for DuraFlex Service
We’ve worked on Duraflex in Manhattan and Brooklyn long enough to know how the product holds up, and where it doesn’t. When a homeowner calls us about a DuraFlex liner, they aren’t getting a trainee learning on the job. Hank Delano, the owner, grew up in Eagle Rock and spent years doing hands-on chimney work before starting Flint Chimney Sweep as part of the Garrison Partners family in 2002. He has crawled through enough Brooklyn flues to tell you what’s actually wrong, and he won’t pad the invoice just because you can’t see inside your own chimney. That’s the whole approach: we show you the scope, put the price in writing before any tool comes off the truck, and back every repair with our 365-Day Done Right Promise. The guarantee is written, not implied, and it covers our repairs for a full year. If something fails within that year, we return at no charge. That’s the kind of commitment Brooklyn homeowners want, especially when they’ve dealt with no-show companies before.
We run this shop under The Garrison Standard, the same operating code every Garrison Partners location follows. Our technicians are background-checked and uniformed, so you know exactly who’s walking through your door. And when you call, a live person answers, 24/7. No phone tree. No “we’ll call you back Monday.” That matters when you’re smelling creosote in the parlor on a Saturday night. If you want to understand our broader approach, see our DuraFlex sales & service page.
Common DuraFlex Chimney Cleaning Problems We Solve in Brooklyn
DuraFlex liners are good products, but no liner is immune to what this borough does to a chimney. Here are the five issues we see most often on DuraFlex systems across Brooklyn service area:
- Corrosion pitting on 316L and 304 liners. Brooklyn’s humid, salt-laden coastal air works on stainless steel year-round. Chimneys near the waterfront show pitting faster than ones inland. We inspect for pinholes and thinning walls during every sweep, because a pitted liner can leak combustion gases into the house.
- Kinked or deformed liner sections from aggressive sweeping. A lot of Brooklyn chimneys have tight flues in older brownstone masonry. When a previous sweep used an oversized brush, the flexible liner takes the abuse. A kinked section restricts draft and traps creosote behind it. We use properly sized poly brushes to clear the system without reshaping the stainless.
- Glazed creosote buildup on wood-burning systems. Brooklyn has thousands of wood-burning fireplaces, and plenty of people burn unseasoned wood. That produces hard, shiny creosote that sticks to the inside of a DuraFlex liner like varnish. Mechanical scraping scratches the liner; we use chemical glaze removers and poly brushes instead.
- Liner separation at the appliance connector. DuraFlex liners flex, which is the point, but if the original install didn’t include proper support brackets, the connector can sag or pull loose. That’s especially common in rowhouse chimneys where the liner runs through a narrow, twisting flue. A separated connector lets smoke and carbon monoxide into the living space, so we check this on every call.
- Cap and component failure from weather exposure. DuraFlex caps sit at the very top of the flue, catching every storm, freeze cycle, and gust off the water. Broken or missing caps let rain inside, which accelerates rust damage on the liner below. We keep cap replacement components on the truck for common DuraFlex sizes.
DuraFlex Service in Brooklyn: What Local Conditions Mean for Your Equipment
Here’s something specific to Brooklyn that you won’t read on a generic chimney site. Many Brooklyn rowhouses share a single masonry chimney stack with multiple flues running side by side. One flue might carry a wood stove liner, another a furnace vent, another an unused fireplace. When a neighboring flue overheats or a burning ember gets where it shouldn’t, the flue tile between them can crack or spall, and that failed masonry can fall against your DuraFlex liner. Heat transfers through the common wall and stresses the stainless steel. Debris from a broken flue above can drop into your liner and block it. We see this regularly in the older housing stock around Dean Street in Boerum Hill and similar blocks where attached homes share a central stack. It’s almost unheard of in detached suburban construction. For a DuraFlex owner in Brooklyn, this means flue-by-flue isolation is critical during cleaning. We camera-inspect and isolate the specific flue we’re working on, then check the shared masonry around it for damage that could be pushing against the liner. That inspection catches problems a routine sweep misses.
Hank’s rule on this is simple: “Tell me what you’re seeing, I’ll tell you what it means.” If a camera shows a cracked flue tile pressing your liner, you’ll know exactly what that means for your system and what it costs to fix.
DuraFlex Models & Products We Service in Brooklyn
We service the full DuraFlex product line you’re most likely to find in Brooklyn homes. That includes DuraFlex 316L stainless steel flexible liner kits, which are the standard for wood-burning and coal-burning appliances, and DuraFlex 304 stainless kits, common for gas and oil systems. We also work on DuraFlex insulation wrap and mesh sleeve systems, which are used when a liner needs an insulated air gap against a masonry flue. Custom caps and component accessories round out what we handle.
When we repair a DuraFlex system, we use genuine DuraFlex components, including liner sections, caps, and insulation wraps, whenever they’re available. Aftermarket flexible liners often have thinner walls and weaker corrosion resistance, and in Brooklyn’s coastal air, that difference shows up fast. We keep common DuraFlex fittings stocked on our service vehicles so a straightforward connector replacement or cap installation doesn’t require a return trip. For a comparison of how we handle DuraFlex in other markets, see DuraFlex service in Houston.
DuraFlex Service Pricing in Brooklyn
A standard DuraFlex chimney cleaning in Brooklyn typically runs $189 to $289, depending on the liner’s condition, the height of the stack, and whether glazed creosote removal is required. If you need a Level 2 camera inspection alongside the sweep, that runs $150 to $250 more. Minor repairs, like replacing a cap or a connector section, start around $120 for parts and labor; a full liner replacement in Brooklyn generally runs $2,500 to $5,000, with the lower end reserved for straightforward single-story flues and the high end covering shared-stack rowhouses with access problems.
Here’s what a free estimate includes: we inspect the system, camera the liner if needed, and give you a written price before any work begins. That’s non-negotiable in our shop. The number on the invoice is the number you approved. No mid-job surprises, no “while we’re in there” add-ons. Call (830) 251-4560 for an exact quote on your DuraFlex system.

FAQs – DuraFlex Chimney Cleaning in Brooklyn
Yes, we clean DuraFlex liners using properly sized poly brushes and chemical glaze removers designed for stainless steel. The damage we find most often came from a previous sweep that forced a metal brush through a tight flue. We inspect before we sweep and select the brush to the liner’s actual diameter, not the rowhouse’s average. Call (830) 251-4560 to schedule a cleaning.
Rust spots on a DuraFlex liner in Brooklyn almost always mean corrosion pitting from humid, salt-laden air, especially if your home is near the waterfront. 316L stainless resists corrosion better than 304, but neither is immune to years of Brooklyn marine air. We camera-inspect the liner to see how deep the pitting goes; shallow surface marks are often serviceable, but through-pitting requires liner replacement. Call (830) 251-4560 for a free inspection.
A Level 2 inspection is not strictly necessary for a routine sweep, but in Brooklyn’s shared-stack rowhouses we recommend it if the chimney hasn’t been camera-inspected in the last two years. The camera shows whether a neighboring flue’s damage is pushing against your liner, something no routine sweep will reveal. The inspection runs $150 to $250 and is worth it for any chimney with a DuraFlex liner installed more than a few years ago.
Yes, if the damage is limited to one section, we can replace that section using a DuraFlex connector and matching stainless components. If the liner is pitted through in multiple places or kinked beyond safe use, patching isn’t honest, and we’ll recommend full replacement. We’ll show you the camera footage and let you decide with your own eyes. Call (830) 251-4560 for an exact quote.
Yes, we service Duraflex service in Staten Island and DuraFlex liners in both gas and wood-burning fireplaces across Brooklyn. Gas systems present different wear patterns, mostly condensation-related corrosion on 304 liners, while wood systems build creosote. We stock components for both. Call (830) 251-4560 and we’ll schedule the right technician for your fuel type.
