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 SW (stainless flexible liner) - creosote bridging in long horizontal runs. The SW’s corrugated wall traps more particulate in horizontal or offset sections than smooth-wall alternatives, especially when homeowners burn unseasoned hardwood common in Downers Grove’s tree-dense neighborhoods like Lester and Randall Parks. We remove Class II and III creosote with rotary whips sized to the SW’s exact inner diameter, then camera-scan to confirm the wall is clean to bare metal, not just “swept.”
- DuraFlex AL (aluminum liner) - premature corrosion from condensate in gas appliance flues. The AL series is rated for gas-only, but we regularly find it installed with orphaned water heaters or high-efficiency furnaces that produce acidic condensate the aluminum cannot survive. During our sweep, we test flue gas temperature and dew point; if the AL shows pitting or white oxide bloom, we document it with photos and quote a stainless replacement before the liner fails through.
- DuraFlex DSA (double-wall solid-pack) - joint separation at termination above the roofline. The DSA’s telescoping sections can work loose from thermal cycling and wind load on Downers Grove’s exposed ridgelines, particularly near the I-88 corridor where gusts are higher. Our sweep includes a roof-level inspection of the termination; if we find a separated joint, we reseat with proper DuraFlex-compatible fasteners and sealant, not generic hardware that voids the remaining warranty period.
- DuraFlex relining collars and top plates - gasket hardening and fastener corrosion. The rubberized gaskets on DuraFlex top plates degrade faster than the liner itself, especially where ice damming occurs on older Downers Grove homes with complex roof crickets. We stock replacement collars and plates from our Haven buying network; if the liner body is sound, we replace only the failed component, not the entire system.
- DuraFlex Pro (smooth-wall flexible) - factory coating delamination in high-heat overfires. The Pro’s interior coating can bubble or flake after a significant overfire event, leaving bare stainless that collects creosote differently than the designed surface. We identify delamination with camera inspection and measure affected length; spot repair is possible for short sections, but full replacement is quoted when the damage exceeds 18 inches or occurs below the smoke chamber.
Our DuraFlex Chimney Cleaning & Sweep Process
- 1
Live booking and tech assignment. Your call is answered by a person, not a menu. We assign a named, background-checked technician and text you when they depart for your Downers Grove home.
- 2
NFPA 211 Level 2 inspection with camera. We run a chimney camera the full length of your DuraFlex flue, documenting liner condition, creosote class, joint integrity, and termination status. Clause 4 of the Haven Standard requires this photo record on every job - we have done so since 2009.
- 3
Written diagnosis and price. Corrine Halstead reviews the footage with you on-site or via shared link. We state what we found, what it costs, and what the warranty covers. The camera does not lie, and neither does the written price.
- 4
OEM or qualified aftermarket parts selection. For DuraFlex repairs, we source from our Haven network - DuraFlex direct, or HeatShield and Gelco where cross-compatibility exists and cost serves the customer without compromising safety.
- 5
Sweep, repair, and post-work testing. Creosote is removed, repairs completed, and the system is smoke-tested or draft-tested to confirm proper function. We leave your fireplace and work area clean.
- 6
Documented record delivery. You receive photos, camera footage, the written scope, and the written warranty before we leave. Your record is archived for future reference.

Price moves with liner diameter, story height, roof pitch, and accessibility. A third-story DuraFlex run through a tight chase in a Downers Grove Victorian near Main Street costs more than a straight basement-to-roof replacement in a 1990s ranch. We measure and photograph everything before quoting. Estimates are free - call (331) 253-4980.
Why Downers Grove Homeowners Call Emberly Chimney Cleaners Downers Grove for DuraFlex Work
We are an independent DuraFlex service provider - not affiliated with or authorized by the manufacturer - which means we choose parts based on what your flue actually needs, not what a brand catalog pushes.

Since 2009, we have completed more than 38,000 chimney inspections and cleanings, every one with a written price before work started and a documented record when finished. We also service HeatShield and Gelco systems, so if your DuraFlex installation has hybrid components or a previous repair using another brand, we do not need to call in a second contractor. Free second opinions on any competitor’s written estimate are always available.
FAQs
No. Proper annual sweeping by a qualified professional is required to maintain DuraFlex warranty coverage. We document our work with photos and a written report, which you can submit if a warranty claim ever arises. Call (331) 253-4980 to schedule - estimates are free.
Most DuraFlex replacement components arrive through our Haven buying network within two to four business days. For common top plates, collars, and standard liner diameters, we often stock inventory or can source from regional distributors serving the Chicago metro area. We do not start work until parts are in hand, so your downtime is limited to one appointment, not a string of them.
Depends on what the camera shows, not the calendar. A well-maintained DuraFlex stainless liner can last 15 to 20 years; an aluminum liner in a condensing environment may fail in under 10. We camera-inspect, show you the footage, and quote both repair and replacement options when both are viable. Nothing is recommended without photo evidence you can see for yourself.
NFPA 211 recommends annual inspection; sweeping frequency depends on use and fuel. Downers Grove homeowners who burn cordwood two to three times weekly typically need annual sweeping. Occasional gas fireplace users may extend to every two years, but the inspection should still happen yearly to catch liner deterioration, animal intrusion, or moisture damage before they become hazardous.
Class I creosote becomes Class II, then Class III - a hard, tar-like deposit that insulates the flue, reduces draft, and can ignite at temperatures as low as 451°F. A DuraFlex liner with significant buildup also corrodes faster because acidic condensate sits against the metal instead of venting cleanly. The camera shows the progression clearly; we have shown many Downers Grove homeowners the difference between a maintained liner and one that has not been cleaned since installation.
