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.
DuraFlex Chimney Cleaning & Sweep in Easton: What to Know First
We provide independent DuraFlex chimney cleaning and sweep service in Easton, Pennsylvania, with most inspections and cleanings completed in a single visit and upfront pricing agreed before we start. A standard DuraFlex sweep with Level 1 inspection runs $189-$289 in the Easton market, while Level 2 camera inspections for suspected liner damage range $289-$449. We’re not affiliated with DuraFlex - we work on their products because they show up in local homes, and we know where they tend to give trouble.
This page is for Easton homeowners with a DuraFlex chimney liner, cap, or component who need it swept, inspected, or diagnosed. Maybe you’ve noticed draft issues, creosote buildup, or you’re due for your annual NFPA 211 sweep before burning season. Call (610) 756-1504 - a live person answers, any hour.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW series: creosote glazing in the flex joints. The SW’s stainless corrugations trap more condensation than smooth-wall liners, especially during Easton’s freeze-thaw cycles when the chimney runs cold-start. We use polypropylene whips sized to the corrugation pitch, not standard wire brushes that flatten the flex and void the warranty. After cleaning, we camera every joint.
- DuraFlex 316Ti and 304 alloys: premature weld-seam corrosion. The 316Ti resists acid better than 304, but both develop pinhole leaks at circumferential welds when creosote sits through humid Lehigh Valley summers. We catch this with Level 2 camera inspection; if the seam is compromised, we document it with photos and quote HeatShield or a new DuraFlex section - no guesswork.
- DuraFlex relining kits: improper original slope causing debris pooling. Installers who don’t account for Easton’s older masonry chimneys - many with slight offsets from settling - create low spots where soot and moisture collect. We measure slope with a laser level during cleaning and recommend correction if water is pooling above the smoke chamber.
- DuraFlex termination caps: mesh screen clogging from cottonwood and maple seed. The Delaware Canal corridor and older neighborhoods near College Hill see heavy spring seed drop that packs DuraFlex cap screens solid. We remove and clean the cap assembly, check for galvanic corrosion where dissimilar metals meet, and replace with Gelco stainless if the original has thinned.
- DuraFlex connector pipes: thermal expansion fatigue at the appliance collar. Frequent on-off cycling with Easton’s shoulder-season heating patterns cracks the flex-to-rigid transition. During sweep, we inspect this joint with a borescope; if we find fatigue, we source OEM DuraFlex couplers or fabricate a proper expansion joint - no hose clamps and prayers.
Our DuraFlex Chimney Cleaning & Sweep Process
- 1
Call and schedule. A live person answers, asks what you’re burning, how often, and any symptoms. We quote the inspection level and price range before booking.
- 2
Arrival and protection. Our tech lays runners, inspects the appliance and exterior, and confirms the DuraFlex model from any tags or our records.
- 3
Cleaning with DuraFlex-appropriate tools. We match brush or whip type to the liner alloy and corrugation pattern. For SW series, we avoid anything that could catch a weld seam.
- 4
Level 1 or Level 2 inspection. Level 1 is visual and manual. Level 2 adds camera documentation of the full flue, smoke chamber, and accessible exterior - photos you see on a tablet, with a plain-English verdict.
- 5
Parts decision if needed. We stock common DuraFlex fittings and carry HeatShield and Gelco alternatives. OEM when it matters for warranty, quality aftermarket when it doesn’t.
- 6
Test fire, cleanup, and written report. We verify draft and spillage, leave no ash in the hearth, and hand you the sweep report with our 90-Day Done Right Promise attached.

Why Easton Homeowners Call Hearthstone Chimney Co. for DuraFlex Work
We’ve swept chimneys in Easton since 1984.

We also service HeatShield and Gelco systems, so if your DuraFlex component needs replacement, we have options beyond a single brand catalog.
FAQs
No, if it’s done properly. DuraFlex warranties require annual NFPA 211 maintenance by a qualified technician using tools that don’t damage the flex corrugations or welds. We follow those practices and document the service date for your records. Call (610) 756-1504 if you need a copy for warranty filing.
We stock common DuraFlex connectors, couplers, and caps on our trucks, and our suppliers in the Lehigh Valley region carry most SW and 316Ti sections with 24-48 hour turnaround. For obsolete sizes, we can fabricate transitions or source compatible HeatShield or Gelco alternatives. We’ll tell you before ordering if there’s a wait.
Cleaning fixes buildup; repair fixes physical damage. During our Level 2 camera inspection, we look for weld-seam corrosion, flex flattening, and offset gaps. If we find damage, we show you the photo and explain whether it’s urgent or can wait. No camera evidence, no recommendation for repair. Call (610) 756-1504 to schedule.
Once per burning season for wood-burning appliances, per NFPA 211. Easton’s humid summers and hard freeze cycles accelerate corrosion if creosote is left in the flue, so we recommend scheduling before the first fire, not after. Gas appliances with DuraFlex venting need annual inspection though typically less aggressive cleaning.
Creosote hardens into glaze that standard brushes won’t remove, accelerating corrosion in the flex joints and increasing chimney fire risk. In Easton’s climate, we’ve seen SW liners develop pinhole leaks within three skipped seasons. The sweep itself is the cheap part. Call (610) 756-1504 for a free estimate.
