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.
DuraFlex Chimney Cleaning in Detroit, NY | Emberly Chimney Cleaners
We provide independent DuraFlex chimney cleaning and liner service across Detroit, and the thing that separates our work here is what the camera shows us inside the city’s century-old brick bungalow flues. DuraFlex liners behave differently in Detroit than they do almost anywhere else, because so many of these chimneys were built for coal, converted for gas in the 1950s, and never relined. That specific history creates failure patterns we see neighborhood after neighborhood, and we document every one of them with a Level 2 camera scan before any work is quoted. Call (980) 580-8641 to book a DuraFlex cleaning or inspection, and we’ll put a written price in your hand before a single tool comes off the truck.
Why Detroit Residents Choose Us for DuraFlex Service
We’ve installed, inspected, and repaired DuraFlex chimney lining systems in Detroit’s vintage chimneys for over a decade, and that experience changes how we approach a cleaning. Most companies can sweep the soot out of a flue. What we do differently is read the liner itself: where the DuraFlex aluminum is thinning, where a flex liner has kinked at the top plate, where a joint has separated because the chimney stack flexed through a freeze-thaw cycle. Our owner, Corrine Halstead, studied building trades technology before spending years working through inspection and cleaning crews, and she’s the one reviewing your camera footage before pricing is discussed. The camera doesn’t soften what it finds. Neither do we. For Detroit homeowners, that means a DuraFlex service call that begins with evidence, not enthusiasm.
Common DuraFlex Chimney Cleaning Problems We Solve in Detroit

Here’s what we actually find when we put a camera down a DuraFlex-lined flue in this city:
- Aluminum liner corrosion from acidic gas condensate. Detroit’s 1950s coal-to-gas conversion left thousands of furnace flues oversized and unrelined, so acidic condensate pools against the liner wall. DuraFlex aluminum 316Ti liners hold up better than older alloys, but they’re still vulnerable when paired with those oversized clay-tile hosts. We see pitting and through-corrosion most often at the bottom elbow where the liner connects to the furnace.
- Tearing and kinking at the top plate and appliance connection. Detroit’s 50 to 70 freeze-thaw cycles a year make century-old masonry move. A flex liner that isn’t given room to expand will tear at the connection points. We check that joint on every cleaning, because a tear there is an exhaust leak into the house.
- Joint separation in multi-story chimney runs. Older Detroit colonials often have chimney stacks that rise two stories past rooflines. When mortar joints open up and the stack flexes, flex liner sections can separate at mid-run connections. The leak isn’t always obvious from the roof level, but the camera sees it from inside.
- Creosote blockage in wood-burning applications. A DuraFlex liner doesn’t exempt a wood-burning flue from annual sweeping. Detroit heating season runs October through April, six months of creosote accumulation. We’ve pulled enough Class III creosote out of lined flues in Rosedale Park to know that the liner doesn’t fix the need for regular cleaning. It just makes the cleaning more critical, because a blocked liner is harder to clear than an unlined flue.
- Water entry at the crown that saturates the liner insulation. Many Detroit bungalows still wear their original crowns, and those crowns are cracked. Water seeps into the gap between the clay tile and the DuraFlex liner, freezes, expands, and puts pressure on the liner walls. We include crown inspection and waterproofing recommendations on nearly every service call in this city, because the two failures usually travel together.

AfterDuraFlex Service in Detroit: What Local Conditions Mean for Your Equipment
There’s a pattern specific to Detroit that shapes DuraFlex chimney cleaning work here more than any other factor: the dual-flue bungalow. Across the city’s bungalow belt, from East English Village on the east side to Rosedale Park and Grandmont-Rosedale on the northwest, the original homes were built with two flues. One served the fireplace. The other served the coal furnace in the basement. When Detroit converted from coal to gas in the 1950s, almost nobody relined those furnace flues. The original clay tiles stayed in place, sized for coal volumes of exhaust that a modern gas furnace doesn’t produce. For DuraFlex owners, this means the aluminum liner installed in that oversized flue is sitting in a cold, damp, oversized cavity. Acidic condensate forms on the liner walls from the outside in, etched into the metal by the same chemistry that corrodes the old clay. We see this failure concentrated in two neighborhoods more than anywhere else: the streets around Outer Drive in East English Village, and the brick bungalow stretch of Rosedale Park. A DuraFlex liner in a properly sized flue will last decades. A DuraFlex liner in an unrelined 1950s conversion flue in Detroit will often corrode through at the bottom elbow within 10 to 15 years. That’s the difference, and it’s visible on camera before you spend a dollar.
DuraFlex Models & Products We Service in Detroit

We service the full DuraFlex product range as an independent provider, which means we’re not a manufacturer-authorized dealer and we don’t answer to a franchise playbook. The systems we see most often in Detroit are the DuraFlex Aluminum 316Ti Liner, the DuraFlex Stainless Steel Rigid Liner used in multi-story masonry runs, the DuraFlex Pro Connect system for gas appliance venting, and the DuraFlex Flex Liner that dominates the bungalow retrofit market. For replacements, we use genuine DuraFlex components when the liner itself is being replaced or extended, because the dimensions and alloy matter. For top plates, caps, and crowns, we’ll pair OEM sections with aftermarket parts that are better suited to Detroit’s weather, particularly stainless steel rain caps that can take a Great Lakes freeze without splitting. This keeps the repair honest and the price proportionate.
DuraFlex Service Pricing in Detroit
Here’s how our DuraFlex work in Detroit is priced. A standard DuraFlex chimney cleaning on a wood-burning fireplace runs $189 to $289, depending on flue length and creosote class. A Level 2 camera inspection, which is included with every cleaning, is $149 when booked alone. For liner repair, expect $350 to $650 for a partial section replacement or elbow repair, and $2,400 to $2,900 for a complete DuraFlex liner replacement in an average Detroit bungalow flue. What drives the cost here specifically is access and condition: a two-story colonial flue that hasn’t been swept since the 1970s will take longer and cost more than a single-story bungalow that was cleaned last year. Every quote is written, itemized, and delivered before work starts, not after the tech is in the house. Call (980) 580-8641 for an exact number. Estimates are free.

FAQs - DuraFlex Chimney Cleaning in Detroit
Why does my DuraFlex aluminum liner keep corroding in my Detroit bungalow?
Because your bungalow almost certainly has the dual-flue setup that defined Detroit’s 1950s coal-to-gas conversion, and the furnace flue was never relined. The aluminum liner sits inside an oversized clay-tile flue where acidic condensate collects and attacks the metal from the outside in, especially at the bottom elbow near the furnace. The fix is not another aluminum liner in the same oversized flue. It’s either a properly sized stainless steel liner or a DuraFlex Pro Connect system with a tee and cleanout that manages condensate. Call (980) 580-8641 and we’ll show you the corrosion on camera before recommending anything.
Can you clean a DuraFlex flex liner that has heavy creosote buildup?
Yes, but the method matters. The liner’s ridges catch creosote more readily than a smooth clay tile, which means a standard brush alone won’t get it all. We use rotary cleaning heads sized to the liner’s internal diameter, then follow with a camera check to confirm the creosote is actually out, not just redistributed. If the buildup is Class III glazed creosote, we’ll tell you that before we start, because the cost and time go up. Heavy creosote in a DuraFlex liner is a blockage risk, not just a dirty flue.
How do I know if my DuraFlex liner is still safe in my century-old chimney?
You don’t know, and neither do we, until the camera goes down. A visual check from the roof or the fireplace won’t show corrosion inside the liner, separation at mid-run joints, or condensate pooling at the bottom. We run a Level 2 inspection with a camera on every visit. You’ll see the footage, not a summary of it. Clause 4 of the Haven Standard requires a documented photo record on every job, and that record is yours to keep. If the liner shows pitting, thinning, or a through-hole, we’ll show you the exact frame and tell you whether repair is viable or replacement makes more sense.
Will a DuraFlex liner fix the acidic smell coming from my gas furnace chimney?
Sometimes, but not always on its own. The acidic smell comes from condensate sitting in the flue, which is usually a direct result of an oversized 1950s conversion flue and a liner that’s not managing the gas appliance exhaust properly. A properly sized DuraFlex Pro Connect liner can reduce the condensate dramatically, but if the existing liner has already corroded through, the smell is exhaust and moisture escaping into the masonry and the house. The camera will show you which scenario you’re in. Call (980) 580-8641 for a written quote on a Level 2 inspection.
Is it worth repairing a DuraFlex liner in a Detroit bungalow, or should I just replace it?
That depends entirely on where the damage is. A corroded bottom elbow or a torn top-plate connection can often be repaired with OEM sections for $350 to $650, and that’s money well spent if the rest of the liner is sound. But if the corrosion runs halfway up the run, patching becomes false economy. You’re paying labor to access a liner that will continue failing elsewhere. Our rule is simple: if a repair buys you fewer than five years, replace the liner. The full replacement runs $2,400 to $2,900 in most Detroit bungalows, and it comes with a written warranty, which is more than the original 1950s non-relining ever gave you.
