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.

A standard DuraFlex sweep and Level 2 camera inspection runs $189-$289 for most Kennesaw homes, with a written price delivered before any work is scheduled.

If your DuraFlex system is in a home near Kennesaw Mountain, in Legacy Park, or anywhere in Cobb County, we write it down before we ask you to decide anything.

How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (stainless steel flexible liner) develops creosote bridging in the corrugations. The helical ridges that make DuraFlex SW so flexible also create turbulence pockets where Class II and III creosote hardens into shelf-like deposits. During a sweep, we use polypropylene whips sized to the liner’s exact diameter, not standard wire brushes that can catch and deform the corrugations. Corrine Halstead’s crew has pulled 3-inch-thick creosote bridges from DuraFlex SW liners in Kennesaw’s older colonials near Kennesaw Mountain, where homeowners burned unseasoned oak through multiple mild winters.
- DuraFlex AL (aluminum) liners suffer galvanic corrosion at the thimble connection when paired with galvanized steel components. This isn’t a cleaning issue until it is: corrosion flakes mix with soot to form a dense, abrasive sludge that accelerates liner wear. We document the thimble condition with camera stills, replace dissimilar-metal fittings with stainless transitions from our Haven network, and note the repair in your written record.
- DuraFlex Pro series liners show premature flex-point fatigue in Kennesaw’s clay-heavy soils. Foundation settling shifts the chimney stack, concentrating stress at the liner’s bend points. During sweep and inspection, we map flex-point wear with the camera and compare against prior visits. If the Pro liner shows crack propagation at the bend, we flag it for sectional replacement rather than full relining, saving the homeowner the cost of unnecessary work.
- DuraFlex tee connectors collect debris at the snout junction. The tee’s horizontal snout is designed for cleanout access, but in practice it becomes a catch basin for fallen mortar, bird nesting, and dense soot accumulations. We disassemble the tee when accessible, vacuum the snout chamber, and reseal with high-temp silicone rated to 600°F. This is standard on every DuraFlex sweep, not an upsell.
- DuraFlex termination caps with factory spark arrestors clog with creosote flakes during high-burn seasons. The mesh arrestors are 304 stainless, but the 1/2-inch mesh spacing traps material that would otherwise exit the flue. We remove, soak, and wire-brush arrestors during sweep service, and we stock replacement caps from Olympia Chimney and Famco when the original DuraFlex cap is too degraded to salvage.
Our DuraFlex Chimney Cleaning & Sweep Process

- 1
Call and scheduling. A live person answers, confirms your DuraFlex product line if you know it, and books a two-hour arrival window. You get a text when your tech is en route.
- 2
Arrival and written price. Your background-checked, uniformed technician arrives with license visible, reviews your chimney’s history, and delivers a written price and scope before touching equipment. Clause 1 of the Haven Standard: have it in writing.
- 3
NFPA 211 Level 2 inspection with camera scan. We run a chimney camera the full length of your DuraFlex liner, documenting liner condition, creosote class, joint integrity, and any flex-point wear. Photos and video are saved to your record under Haven Standard Clause 4.
- 4
DuraFlex-specific sweep and component service. We match brush and whip type to your liner material (stainless or aluminum), service the tee and cap, and inspect all DuraFlex-to-masonry transitions. OEM parts are used when warranty coverage is active; quality aftermarket from Gelco or HeatShield is offered when OEM is unavailable or cost-prohibitive.

FAQs
No, annual sweeping by a qualified professional is required to maintain DuraFlex warranty coverage, provided the work is documented and no abrasive tools damage the liner. We document every sweep with photos and a written report that satisfies warranty claim requirements. If you’re filing a claim, we’ll provide the record at no charge. Call (678) 535-2204 to schedule.
We source both. OEM DuraFlex parts are available through our Haven network for active warranty repairs. For out-of-warranty work or discontinued components, we use quality aftermarket from Gelco, Olympia Chimney, or Famco with equivalent or superior specifications. We name the source in your written price before you decide.
The camera scan tells us. During your Level 2 inspection, we look for crack propagation, flex-point fatigue, corrosion penetration, and joint separation. If the liner is dirty but structurally sound, you need only a sweep. If we find damage, we show you the camera stills and deliver a separate written price for repair. Nothing is recommended without photo evidence you can see. Call (678) 535-2204 for a free estimate.
NFPA 211 recommends annual inspection; sweep frequency depends on use. Kennesaw’s mild winters mean some homeowners burn only 20-30 fires per season and can stretch to every 18-24 months with light use. Heavy burners, those using unseasoned wood, or homes with DuraFlex SW liners showing creosote bridging should sweep annually. We note your burn pattern and recommend a return date in your written report.
Class I creosote becomes Class II, then Class III glazed creosote that standard brushes won’t remove. In DuraFlex liners, this buildup narrows the flue diameter, restricts draft, and increases chimney fire risk. The corrugations in DuraFlex SW make this progression faster than in smooth-wall liners. A neglected DuraFlex AL liner can corrode through at the thimble, leaking combustion gases into the home. The camera inspection during a routine sweep catches this before it becomes a safety issue. Call (678) 535-2204 to book.
