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 North Atlanta, GA | Ashby Chimney Atlanta
Ashby Chimney Atlanta provides independent DuraFlex Chimney Sweep in North Atlanta, including cleaning and repair across the area. We’re not a DuraFlex dealer, and we’re not tied to a manufacturer’s warranty script. What we are is a crew that has opened enough DuraFlex liners after North Atlanta’s humid, low-burn seasons to know exactly how glazed creosote forms in the corrugations and what it takes to get it out without wrecking the liner in the process. Call (678) 263-7908 for a written estimate.
Why North Atlanta Residents Choose Us for DuraFlex Service
Because we show up with the price already written down, and we don’t touch a brush until we’ve looked inside the flue. Nathan Corliss founded this shop on that principle. He grew up in Los Angeles, trained at LA Trade-Technical College, and spent years working flues and fireboxes before bringing that flat-price, Chimney Inspection in North Atlanta-first approach to Atlanta. For the last several years, he and his crew have been the ones homeowners call from Buckhead bungalows to older places near Grant Park where the masonry hasn’t been touched since the Carter administration. Our techs know DuraFlex liners the way a mechanic knows a specific engine. We stock OEM DuraFlex couplings, connectors, and top plates in our North Atlanta vehicles, so when a liner joint has separated or a top plate is rusted through, we’re not waiting on a parts shipment. We complete most DuraFlex cleaning and minor repair jobs in one trip. And every job, every time, gets a written guarantee. If a covered repair fails inside the guarantee period, we return and fix it at no charge. That’s the 365-Day Done Right Promise, and it’s written on the invoice, not mumbled in a sales pitch.

Common DuraFlex Chimney Cleaning Problems We Solve in North Atlanta
- Glazed creosote packed into liner corrugations. North Atlanta’s mild winters mean homeowners burn low, smoldering fires instead of hot, fast ones. That low-temperature combustion produces third-degree creosote that hardens into a tar-like glaze inside the ribs of a DuraFlex 316L liner. Standard wire brushes skate right over it. We use polypropylene or steel rotary heads sized to the liner’s diameter to break it loose without scoring the stainless.
- Pinhole corrosion at liner seams. The acidic creosote that builds up in our humid climate sits in the corrugations and eats at the thin points where the liner was welded or crimped. Add months of summer humidity, and those pinholes grow. We camera-inspect the full liner after every cleaning, and we’ll show you the footage on the spot. No pinhole gets patched blind.
- Sagging or kinked liner sections. Freeze-thaw cycles in North Atlanta shift chimney masonry by tiny increments every winter. An uninsulated exterior chimney is the worst case – the stack moves, and a flexible liner that was pulled tight during installation develops a sag or kink that becomes a creosote trap and a fire risk.
- Disconnected liner joints at the tee or appliance connector. Thermal expansion and contraction in an uninsulated exterior chimney works couplings loose over time. The joint separates just enough for flue gas and condensation to leak into the chase. We find this constantly in Sandy Springs and Roswell homes built in the 1990s and early 2000s.
- Improper liner sizing or installation from a previous contractor. A DuraFlex liner that wasn’t sized correctly – too large for the appliance, or stretched too thin on installation – will never draft right and will always build creosote faster than it should. We measure and verify before recommending any cleaning schedule or repair.
DuraFlex Service in North Atlanta: What Local Conditions Mean for Your Equipment
Here’s the thing about North Atlanta that doesn’t show up on a spec sheet. Most of the chimneys in this region are exterior-adjacent, meaning the flue runs up an outside wall rather than through the center of the house. That means the liner is cold for long stretches of every burn season. When you light a low fire on a humid December night, the temperature difference between the warm flue gas and the cold stainless drives condensation inside the liner. That condensation mixes with creosote to form a glazed, glassy layer that is harder to remove and more flammable than the powdery creosote colder climates produce. In Dunwoody and Sandy Springs, where 1980s and 1990s homes with original clay tile liners are now getting their first stainless reline, we regularly pull DuraFlex liners that look like they’ve been coated in black enamel. A nylon brush will snap on that stuff. We calibrate every rotary head to the liner’s inner diameter and run two passes when the glaze is heavy. If you want to understand why your neighbor’s flue catches fire while yours just smokes, that humidity difference is the answer.
DuraFlex Models & Products We Service in North Atlanta
We clean, inspect, and repair all common DuraFlex liner lines: DuraFlex 316L for wood stoves and fireplace inserts, DuraFlex AL for gas appliances, DuraFlex 304 for higher-temperature coal and wood applications, and DuraFlex Pro for heavy-duty smooth-wall installations. When a liner section is sound enough to salvage, we repair with OEM DuraFlex couplings, connectors, and top plates. When it isn’t, we say so plainly. Patching a liner that’s riddled with pinholes is a band-aid, and we don’t sell band-aids. We’ll recommend a full replacement with a quality liner instead. That’s the difference between independent service and a parts counter.

FAQs – DuraFlex Chimney Cleaning in North Atlanta
High ambient humidity means the flue gas inside the liner carries more moisture, and that moisture condenses on the cooler stainless walls of an exterior chimney. The condensation bonds with acidic creosote to form a glaze that accelerates corrosion at the liner’s seams and corrugation valleys. Over time, that corrosion creates pinholes, which then let flue gas and moisture escape into the chimney cavity. That’s the short version of why liners in North Atlanta corrode faster than liners in drier climates like Colorado or Arizona. If you suspect pinholes, call (678) 263-7908 and we’ll camera-scope the liner to confirm what’s going on.
Yes. We use rotary whip systems with polypropylene or steel heads that are sized precisely to the liner’s inner diameter. The key is matching the head to the liner, because a head that’s too aggressive can score the stainless and create rust points. After mechanical cleaning, we run a chemical treatment when the glaze is severe, then camera-inspect the full length to verify the liner is clean and intact. If the glaze is too thick for a safe clean, we’ll tell you that too.
DuraFlex 316L is stainless steel rated for wood-burning appliances, meaning it can handle the creosote and the higher temperatures that come with wood fires. DuraFlex AL is aluminum, and it’s only for gas appliances. Running a wood stove or fireplace through an aluminum liner is dangerous. If you’re not sure which liner you have, we can tell you in about five minutes with a camera inspection. Call (678) 263-7908 and ask for a Level 2 inspection.
Freeze-thaw movement in the chimney stack is the usual culprit. Exterior masonry expands and contracts with every freeze, and that tiny movement transfers to the liner. If the liner wasn’t properly supported or the couplings weren’t locked at installation, the joints work loose and the liner can sag or kink. We see it most often in North Atlanta homes with uninsulated exterior chimneys built in the 1980s and 1990s. The fix is a liner pull-and-inspect, and if the sections are sound, we re-support and re-couple with OEM parts.
If the pinholes are isolated to one or two spots and the surrounding steel is solid, an OEM coupling or a welded patch can buy you several more years. If the pinholes are scattered along the liner or the corrosion has thinned the walls, replacement is the honest answer. We’ll camera the full liner and show you the footage before we recommend anything. No repair gets recommended without visual evidence, and no replacement gets sold just because a warranty ran out. Call (678) 263-7908 for a written, no-pressure estimate.
