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 Liner & Rebuild in Easton: What to Know First
We provide independent DuraFlex chimney liner & rebuild service in Easton, with most liner replacements and partial rebuilds completed in a single visit after our Level-2 camera inspection. Our no-hassle upfront pricing means the estimate we give is the invoice you pay - no surprises when the job is done. Typical DuraFlex liner jobs in Easton run from $1,800 to $4,500 depending on flue height, diameter, and whether the surrounding masonry needs rebuilding.
This page is for Easton homeowners who know they’ve got a DuraFlex liner installed and need straight answers about what’s failing, what it’ll cost, and who can fix it without upselling work that can wait. If the flue is clear and the mortar is sound, that’s all the good news you need. Call (610) 756-1504 to speak with a live person - any hour, any day - and we’ll book your free estimate.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (Stainless Wall) liners develop creosote bridging at the flex joints. In Easton’s older colonials near the Delaware Canal, we’ve seen SW liners installed in the 1990s and early 2000s that never got the maintenance DuraFlex specifies. The corrugated walls trap creosote in the valleys between ridges, hardening into a glazed layer that narrows the flue and creates a fire hazard. We remove the liner when necessary, mechanically clean the flue walls, and reinstall with proper offset clearance - or replace with a new DuraFlex SW if the original has thinned from acid corrosion.
- DuraFlex AL (Aluminum) liners corrode from the outside in when used with gas appliances. Easton homeowners sometimes inherit these from prior owners who converted wood fireplaces to gas inserts without upgrading the liner. Aluminum can’t handle the acidic condensate from modern gas combustion. We pull the damaged AL liner, verify the flue is sized correctly for the appliance, and install a DuraFlex SW or a compatible stainless alternative from Olympia Chimney - whichever fits the chimney geometry and your budget.
- DuraFlex Pro liners separate at the seam welds in tall, straight runs. The Pro series uses a lighter-gauge steel that saves weight but can work-harden at seam joints over years of thermal cycling. In Easton’s three-story Victorians along College Hill, we’ve found Pro liners that have pulled apart 15 to 20 feet up, venting combustion gases into the chimney cavity. We camera-locate the breach, extract the failed section, and replace with a heavier-gauge DuraFlex SW or a custom-fabricated Olympia Chimney rigid section where the flue is straight enough to accept it.
- DuraFlex liner top connections loosen where they meet the collar or rain cap. The clamp-band system DuraFlex uses tolerates some movement, but Easton’s freeze-thaw cycles and the occasional ice dam on north-facing slopes will vibrate the assembly loose over seasons. We find caps tilted or blown off entirely, letting water pour directly onto the liner. We reseat the connection with a proper expansion-allowing fastening, replace deteriorated gaskets with OEM or better, and install a Gelco cap if the original is too far gone.
- Partial chimney rebuilds expose DuraFlex liners to mortar contamination. When the exterior brick above the roofline is spalling - common in Easton where pre-1940s brick was fired softer and absorbs more moisture - we rebuild the stack and often find the liner cemented in place by sloppy previous rebuilds. The alkaline mortar attacks stainless steel. We free the liner without damaging it when possible, or replace it if pitting has begun, and install proper clearance packing to prevent it happening again.
Our DuraFlex Chimney Liner & Rebuild Process
- 1
Live answer and scheduling. A real person picks up at (610) 756-1504, notes your DuraFlex model if you know it, and books a Level-2 camera inspection - usually within a few days, faster if you’ve got active water infiltration or a blocked flue.
- 2
Camera inspection and documentation. Our technician runs a high-res camera the full length of your flue, photographing every joint, seam, and surface condition. You see the images on a tablet right there. Russell Haines or a senior tech delivers a plain-English verdict: what’s failing, what’s fine, what can wait.
- 3
Parts decision: OEM DuraFlex vs. quality aftermarket. We stock common DuraFlex diameters and carry Olympia Chimney and Gelco alternatives where geometry or availability makes them the better fit. We explain the trade-off - warranty coverage, gauge, expected lifespan - and you decide. No default to the most expensive option.
- 4
The repair or rebuild. Background-checked, uniformed technicians complete most DuraFlex liner replacements and partial rebuilds in one visit. For full rebuilds, we stage materials and return to finish, keeping the chimney capped and weather-tight between visits.
- 5
Post-repair testing and photo report. We run a final camera pass, verify draft and clearances, and hand you a dated sweep report with photos. The 90-Day Done Right Promise goes in writing before we leave - if it’s not right, we make it right, no paperwork, no arguing.
- 6
Cleanup and follow-up. We haul away the old liner and debris. Our office checks in within two weeks to confirm you’re satisfied. Most Easton customers who call us once call us back for annual sweeps.

That’s how we’ve worked since 1984, and it’s how we’ll keep working in Easton.
FAQs
The original DuraFlex warranty expired years ago for most Easton installations, and DuraFlex warranties are manufacturer-to-dealer, not transferable to homeowners in most cases. We use OEM-spec or better replacement components, and our 90-Day Done Right Promise covers our workmanship independently. Call (610) 756-1504 if you’d like us to review what warranty paperwork you have - estimates are free.
Some DuraFlex AL diameters are discontinued, but we stock compatible stainless liners from Olympia Chimney that match the flue geometry and exceed the original corrosion resistance. For early SW models, current DuraFlex components often retrofit with minor adapter adjustments our techs carry on the truck. We confirm parts availability during your camera inspection, not after we’ve torn your chimney apart.
If the camera shows isolated seam separation or a damaged top connection and the liner wall thickness is still within spec, repair is usually the right call. If we find multiple breaches, wall thinning below 0.005 inch on SW models, or alkaline mortar contamination from a previous rebuild, replacement saves you from a second service call next season. We show you the camera evidence and explain both paths - no default to the bigger job.
Most single-flue DuraFlex liner replacements in Easton are completed in one day, including extraction, flue prep, installation, and testing. Jobs with multiple offsets, tight cleanout access in basements near the Delaware Canal, or simultaneous partial rebuilds may run into a second day. We tell you the expected duration in your upfront estimate so you can plan.
A compromised liner vents combustion gases into your home or chimney cavity, raising carbon monoxide risk and the chance of a chimney fire from creosote buildup in hidden spaces. In Easton’s climate, water infiltration through a failed top connection accelerates masonry damage every freeze-thaw cycle. That said, if our camera shows minor surface rust and the seams are intact, we’ll tell you it can wait until your next scheduled sweep. We don’t invent urgency. Call (610) 756-1504 and we’ll give you the honest timeline.
