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 wall) liners with separations at the collar joints. The SW series uses a snap-lock collar system that can work loose after repeated thermal cycling, especially in Chesterbrook’s freeze-thaw winters where the flue temperature swings from ambient to 400°F in under an hour. We find the gap with a camera scan, then reseat or replace the collar with a factory-spec DuraFlex component or a compatible stainless joint from our Olympia Chimney stock, depending on what’s in stock and your timeline.
- DuraFlex Pro gas inserts with failed thermocouples producing pilot dropout. The Pro series thermocouple sits in a tight pilot bracket that collects dust from Chesterbrook’s dry winter indoor air; the connection fatigues after 5-7 years. We test millivolt output at the valve, replace with an OEM Robertshaw or compatible if the customer prefers, and document the reading in the photo record.
- DuraFlex AL (aluminum) liners corroded by condensate in high-efficiency gas conversions. Aluminum flue liners are not rated for the acidic condensate produced by 90%+ AFUE furnaces or direct-vent gas inserts, but we see them installed anyway in 1980s Chesterbrook townhomes near the Corporate Center. The fix is a full liner swap to DuraFlex SW or a stainless equivalent, camera-documented before and after, with written price for both options.
- DuraFlex chimney caps with mesh fatigue and wildlife intrusion. The standard DuraFlex cap mesh is 5/8″ stainless weave that squirrels can force in Chesterbrook’s oak-heavy neighborhoods, especially near Valley Forge Park where the population density runs high. We replace with a Gelco or Famco cap with 3/8″ mesh or add a custom cricket if the roof pitch directs water behind the cap.
- DuraFlex relining jobs with incomplete smoke chamber parging. When a previous installer dropped a DuraFlex liner but skipped the smoke chamber (the funnel-shaped area above the firebox), creosote pools in the corbelled brick and creates a Class III glazed deposit that no sweep brush will touch. We camera the chamber, parge with HeatShield Cerfractory Foam if the dimensions allow, or quote a full chamber rebuild with written scope and price.
Our DuraFlex Fireplace Services Process

- 1
Call and schedule. A live person answers 24/7. We ask the model or series if you know it, the fuel type, and the symptom. We book a two-hour arrival window.
- 2
NFPA 211 Level 2 inspection with camera. Corrine or a uniformed, background-checked tech runs a camera down the flue and photographs the firebox, smoke chamber, damper, and exterior termination. Clause 4 of the Haven Standard requires this photo record on every job, and we have done so since 2009.
- 3
Written findings and price. We show you what the camera found, name the part or repair needed, and deliver a written price and scope before any work begins. Haven Standard Clause 1: have it in writing.
- 4
Parts decision and repair. If your DuraFlex component needs replacement, we source OEM through our DuraFlex buying network or a quality aftermarket equivalent from Olympia Chimney or Famco if the OEM lead time exceeds your comfort. We explain the warranty implication of each.
- 5
Testing and documentation. Gas pressure test, draft test, or combustion analysis as applicable. We photograph the completed work, upload to your record, and stamp the 365-Day Done Right Promise.
- 6
Cleanup and next steps. We haul away old parts, leave the work area as found, and note any maintenance interval in writing. The photo record and invoice are emailed before we leave the driveway.

Why Chesterbrook Homeowners Call Level Two Chimney Chesterbrook for DuraFlex Work

Chesterbrook homeowners do not need another contractor who treats a DuraFlex insert like a generic black box. They need someone who knows the Pro series pilot bracket is a different part number than the standard, who stocks both so the job finishes in one visit, and who writes the finding down before suggesting the fix. The camera doesn’t soften the finding. Neither do I.
We have completed more than 38,000 chimney inspections and cleanings since 2009, every one with a written price before work started and a documented record when done. Our technicians are background-checked, uniformed, and named before they arrive, with a text when they are on the way. Materials come through our Haven buying network from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, sourced to keep customer prices honest. The 365-Day Done Right Promise applies to every DuraFlex job we touch. If it is not done right, we make it right.
FAQs
No, provided the repair uses OEM or equivalent parts and follows manufacturer installation specs. As an independent DuraFlex service provider, we source OEM components through our buying network and document part numbers in your photo record. If a warranty claim arises, you have the paperwork. Call (484) 806-9176 for an exact quote - estimates are free.
OEM DuraFlex parts typically arrive in 3-5 business days through our distributor network. We stock common thermocouples, pilot assemblies, and collar components for same-day repair on the Pro and SW series. If your part is backordered, we quote a quality aftermarket equivalent from Olympia Chimney or Famco with your approval. Call (484) 806-9176 for an exact quote - estimates are free.
We repair when the damage is localized, accessible, and the liner has more than half its useful life remaining. We replace when we find multiple separations, corrosion through more than 30% of the wall thickness, or a material mismatch like AL carrying condensate. The camera shows the difference, and we show you the footage before quoting either path. Call (484) 806-9176 for an exact quote - estimates are free.
Yes, if the existing DuraFlex liner is stainless SW rated for gas exhaust temperatures and the termination clearances meet NFPA 211. We camera the full run, check the cap and collar condition, and quote the insert, gas line, and surround work together. AL liners must be swapped. Call (484) 806-9176 for an exact quote - estimates are free.
NFPA 211 recommends annual inspection for all chimney systems. In Chesterbrook specifically, the oak and hickory canopy produces heavier creosote, and the freeze-thaw cycle stresses collar joints more than milder climates. We see DuraFlex SW separations accelerate after year three without inspection. A Level 2 camera scan catches it before the gap becomes a draft hazard or carbon monoxide risk. Call (484) 806-9176 for an exact quote - estimates are free.
Ready to get your DuraFlex system inspected, repaired, or converted? Call (484) 806-9176 today.
