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.

How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SS (stainless flex liner) - creosote bridging at the corrugation valleys. The 316Ti stainless corrugations that make DuraFlex SS so flexible also create tiny ridges where glazed creosote (Class III) hardens into a brittle shell. In Sandy Springs, we see this most often on homes near the Chattahoochee where oak and hickory are primary fuels and owners burn infrequently, letting moisture set the creosote. We remove the build with rotary chain whips sized to the liner diameter, then camera-scan to confirm the valleys are clean before reassembly.
- DuraFlex SW (smooth-wall) - delamination at the upper flue joint. The smooth-wall construction reduces creosote adhesion, but the seam where the inner wall meets the collar at the top of the flue can separate after 8-12 years of Atlanta thermal cycling. Corrine Halstead’s crew found three of these last quarter in the older ranch homes off Abernathy Road, all showing the same telltale: a thin smoke stain on the exterior brick where exhaust was weeping through the joint. We cut back to sound material, install a DuraFlex OEM top collar or a compatible aftermarket unit from our Haven network, and pressure-test the seam.
- DuraFlex Pro - premature anchor failure in tall, uninsulated chases. The Pro’s heavier gauge helps, but the expansion anchors that suspend it in masonry chimneys work loose when the surrounding brick spalls from freeze-thaw. Sandy Springs doesn’t get brutal winters, but January 2022 dropped to 7°F after rain, and we replaced four Pro liners that month in homes near Hammond Park where the chase caps had leaked for years. We repoint or rebuild the surrounding masonry, reset with upgraded expansion hardware, and install a proper chase cover sourced through our Copperfield supply line.
- DuraFlex AL (aluminum) - corrosion at the water heater or furnace connection. Aluminum DuraFlex is rated for gas appliances only, yet we still find it misapplied to wood-burning inserts in 1980s Sandy Springs renovations. The aluminum pitting starts where condensate pools at the thimble. We replace with DuraFlex SS or, for straight venting runs, an Olympia Chimney stainless equivalent from our Haven buying network, and we document the appliance match in writing so the homeowner has a record for resale.
- DuraFlex tee and wye fittings - cracked snout at the cleanout. The tee’s horizontal snout takes the worst of ash accumulation and tool impact during sweeping. After enough cycles, the metal fatigues at the weld. We stock replacement DuraFlex tees and also carry Gelco-compatible fittings when the original part is backordered. The fix is a cut-and-splice: remove the damaged fitting, measure the offset with a laser, and weld in the replacement with a stainless band clamp backup.
Our DuraFlex Chimney Repair Process

- 1
Call and schedule. A live person answers 24/7. We ask the DuraFlex model if you know it, the appliance type, and the symptom. We book a two-hour arrival window and text when the tech is en route.
- 2
NFPA 211 Level 2 inspection with camera. The tech runs a chimney camera down the full flue length, records the footage, and notes liner condition, joint integrity, and masonry status. Clause 4 of the Haven Standard requires this photo record on every job - we’ve done it since 2009.
- 3
Written price and scope. Before any repair begins, you get a single-page written scope in plain English with line-item pricing and the warranty terms. No verbal estimates, no “we’ll see once we’re in there.”
- 4
Parts decision. We use DuraFlex OEM parts when available and warranty-appropriate. If DuraFlex is backordered or the part is obsolete, we substitute from our Haven network (HeatShield, Gelco, Olympia Chimney) with equivalent or better specs, noted in writing.
- 5
Repair and test. The tech performs the repair, then runs a combustion spillage test or a liner pressure test depending on the job type. The camera goes back down for after photos.
- 6
Documentation and cleanup. You receive the photo record, the written warranty, and a copy of the scope with final sign-off. The 365-Day Done Right Promise is stamped on every document.

Why Sandy Springs Homeowners Call Emberly Chimney Cleaners Sandy Springs for DuraFlex Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of the Sandy Springs inventory runs DuraFlex from the 2005-2015 installation boom. Our techs know the difference between a DuraFlex SS corrugation pattern and a competing brand’s without pulling the label. When DuraFlex parts are scarce, our Haven buying network opens up HeatShield, Gelco, and Olympia Chimney alternatives at prices we don’t markup for scarcity.
The camera doesn’t guess. Neither do we. Every finding is photographed, every price is written, and every job carries the 365-Day Done Right Promise. That’s Clause 1 through Clause 4 of the Haven Standard, and it’s how we’ve worked from the first day.
FAQs
Using an unauthorized service provider does not automatically void a DuraFlex warranty, but warranty claims require proof of proper installation and compatible parts. As an independent DuraFlex service provider, we document every repair with photos, part numbers, and installation details that support any future warranty claim you might file with DuraFlex directly. Keep your paperwork. Call (470) 480-0885 if you need a copy of our documentation format before booking.
Common DuraFlex collars, tees, and flex sections are on our Sandy Springs trucks or available next-day through our Haven supply network. Obsolete DuraFlex AL parts or specialty Pro fittings can take 3-5 business days. We tell you the lead time in the written estimate before you approve the job, and we don’t charge storage if your project waits on parts.
Localized damage - a cracked tee, a separated collar, anchor failure in one section - is usually repairable by cutting out the failed section and splicing in new material. We recommend full replacement when the liner shows multiple joint failures, wall thinning visible on camera, or corrosion patterns that indicate systemic material fatigue. The camera footage decides; we show you the exact frames before quoting either option. Call (470) 480-0885 for a free inspection.
NFPA 211 calls for annual inspection of all chimney systems, and DuraFlex’s stainless and smooth-wall products are no exception. Sandy Springs’ humidity and occasional hard freezes accelerate corrosion and masonry stress that a camera catches before it becomes a leak or a liner collapse. We find most DuraFlex issues at routine inspections, not after failure.
Deferred maintenance on a DuraFlex liner typically progresses from creosote accumulation to corrosion or joint failure, then to masonry damage from leaking exhaust or liner collapse. Carbon monoxide infiltration and chimney fire risk increase as the liner degrades. The cost curve is steep: a $320 cleaning today versus a $2,000+ liner replacement and masonry repair in three years. We mark anything that can safely wait as “monitor” in our report, and we flag what can’t. Call (470) 480-0885 for an honest assessment.
