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 & Sweep in Atlanta: What to Know First
We provide independent DuraFlex chimney cleaning and sweep services across Atlanta, with NFPA 211 Level 2 camera inspections included on every visit and a written price delivered before any work starts. Most DuraFlex systems in Atlanta homes are inspected, swept, and documented within a single appointment. A standard DuraFlex sweep with Level 2 inspection runs $189-$289 in the Atlanta market, depending on creosote buildup and liner accessibility.
This page is for homeowners in Atlanta, Decatur, Brookhaven, and Sandy Springs who have a DuraFlex stainless steel liner, DuraFlex Pro, or DuraFlex SW (smooth-wall) system and need annual sweeping, creosote removal, or an inspection before burning season. We’re not affiliated with DuraFlex Manufacturing; we’re an independent service provider who works on these systems every week. Call (470) 435-7984 to book or get your written estimate.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex Pro: creosote packing at the flex-to-rigid transition. The Pro’s corrugated wall traps more particulate at the collar where it meets the appliance adapter, especially in Atlanta’s humid shoulder seasons when marginal firewood doesn’t fully combust. We remove the adapter, mechanically clean the transition with Pro-specific brushes that match the corrugation pitch, and camera-verify the wall is bare metal before reassembly.
- DuraFlex SW (smooth-wall): hidden delamination behind the seam weld. The smooth-wall design sheds creosote better than corrugated, but the longitudinal seam can separate microscopically after thermal cycling in older Atlanta installations, particularly in 2015-2019 vintage liners we see in Grant Park and Ormewood Park renovations. Our camera catches the hairline gap before it becomes a leak path; if we find it, we document the footage and quote replacement with a new SW section or a transition to HeatShield Cerfractory Foam if the damage is localized.
- DuraFlex standard (304 or 316Ti): accelerated corrosion from bird moisture + creosote. Atlanta’s year-round bird pressure means caps get clogged or knocked askew; moisture follows, and the acid layer under settled creosote eats 304 stainless faster than 316Ti. We don’t just sweep - we pull moisture readings at the flue base and recommend cap upgrades from Gelco or Olympia Chimney if the existing cap is undersized or missing mesh.
- DuraFlex Pro: telescoping section freeze-up. The Pro’s telescoping adjustment section seizes when creosote cement forms between the sliding sleeves, common in Atlanta homes that burn intermittently (weekend-only fires) and let the flue cool between cycles. We free the section with controlled mechanical cleaning, never force it with a pipe wrench (that ovalizes the collar), and apply anti-seize rated for flue temperatures during reassembly.
- DuraFlex SW: improper original sizing creating draft stall. We see this in East Atlanta and Kirkwood flips where a 6″ SW was shoehorned into a 7″ thimble to save money. The liner runs wet, creosote accumulates at double the normal rate, and the homeowner gets a “smoky fireplace” call every November. We sweep, camera the full length, and if the mismatch is confirmed, we quote a proper 7″ SW replacement with a documented photo record - Clause 4 of the Haven Standard requires that evidence.
Our DuraFlex Chimney Cleaning & Sweep Process
- 1
Call intake with DuraFlex model verification. We ask for the liner series (Pro, SW, or standard), approximate install year, and any symptoms. A live person answers, 24/7.
- 2
NFPA 211 Level 2 inspection on arrival. Corrine or a named, background-checked technician runs the camera from top to bottom before touching a brush. The camera doesn’t negotiate - it just shows you what’s there.
- 3
Creosote classification and sweep method selection. Class I (soot) gets rotary sweeping. Class III (glazed) gets chemical pretreatment and mechanical removal. We match the brush to the liner wall - corrugated for Pro, poly for SW if the seam weld is suspect.
- 4
Parts assessment: OEM DuraFlex vs. quality aftermarket. If we find a failed section, we source DuraFlex direct or equivalent 316Ti from our Haven buying network (Olympia Chimney, Famco) if the OEM lead time exceeds your burn schedule. We explain the trade-off in writing before you decide.
- 5
Post-sweep draft test and documentation. We run a smoke pellet or draft gauge (per local Atlanta code reference), then deliver your written scope, photo record, and 365-Day Done Right Promise warranty - all before we leave.
- 6
Cleanup and archive. Your documented record goes into our system, continuous since 2009. Next year, we’ll compare this year’s footage to catch changes early.

We don’t quote over the phone for repair work - we inspect, we photograph, we write the price. Estimates are free, and if you have a competitor’s written quote, we’ll give you a free second opinion. Call (470) 435-7984.
Why Atlanta Homeowners Call Level Two Chimney Atlanta for DuraFlex Work
We’ve swept and inspected more than 38,000 chimneys since 2009, and DuraFlex liners are a regular share of our Atlanta workload - especially in the 1920s bungalows of Inman Park and Virginia-Highland where original clay tile was relined during the 2010s renovation wave. Corrine Halstead and our crew know the difference between a Pro collar that’s dirty and one that’s distorted from over-torque, because we’ve documented both on camera hundreds of times.
Every job carries the Haven Standard: written price before work (Clause 1), verified crew with license number on the page (Clause 2), arrive on schedule with text notification (Clause 3), and documented photo record (Clause 4). The 365-Day Done Right Promise means if we miss something, we make it right. We also service HeatShield and Gelco systems, so if your DuraFlex repair reveals a wider issue, we don’t hand you off to another contractor.
FAQs
No - annual sweeping by a qualified professional is required to maintain DuraFlex warranty coverage, provided the work doesn’t damage the liner. We use brushes sized to your liner’s exact diameter and wall type, and we document the pre- and post-condition with photos so there’s no dispute about what we touched and what was already there. Call (470) 435-7984 to schedule - estimates are free.
Most Pro sweeps finish in 90 minutes to two hours. Class III glazed creosote adds a chemical pretreatment cycle and typically extends the appointment to three hours, or we may schedule a return visit after the solvent has worked overnight. We tell you which scenario applies after the camera inspection, not after we’ve started.
We stock common Pro and SW adapters, collars, and caps through our Haven buying network, and we source direct from DuraFlex for less common sizes. Most standard parts are on our van or available next-day; specialty 8″ SW sections may take 3-5 business days. If your burn schedule is tight, we’ll quote a quality aftermarket equivalent (Olympia Chimney 316Ti) with the same written warranty.
Age alone doesn’t decide it; condition does. We camera the full length, classify any corrosion or seam separation, and give you the footage with a written price for both sweep-only and replacement scenarios. Many 12-year-old DuraFlex liners in Atlanta are fine for another decade; some installed with improper pitch or moisture exposure need attention now. You’ll know before you decide.
Any CSIA-certified sweep can clean a DuraFlex liner, but the Pro’s corrugated wall and telescoping section require brushes and techniques that differ from smooth-wall liners or clay tile. We’ve seen standard poly brushes skip the Pro’s valleys entirely, leaving packed creosote that becomes a fire hazard. Our techs carry Pro-specific equipment and know the failure signatures by sight - that’s the difference between a sweep and a proper DuraFlex service.
