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 SS (stainless) chimney liners: The 316Ti alloy holds up well in West Chester’s freeze-thaw cycles, but we’ve found the collar connections at the insert adapter loosen after 8-12 seasons of thermal cycling. The symptom is smoke rollout on startup, not a draft problem. We reseat with OEM expansion bolts and fresh high-temp gasket - not generic clamp hardware that voids the 20-year warranty.
- DuraFlex Pro aluminum gas venting: Common in 2015-2019 fireplace conversions around West Chester’s Greystone corridor. The Pro’s rolled-seam joints separate if the initial installer didn’t support horizontal runs every 5 feet per DuraFlex spec. We see sagging vent lines dumping condensation into the firebox. Our fix: camera the full run, replace damaged sections with supported Pro stock, and document slope and support spacing for your record.
- DuraFlex SW (smooth-wall) liners: The improved creosote resistance is real, but the inner wall can delaminate if a previous sweep used a rotary chain head at excessive RPM. We find this in older West Chester colonials where aggressive cleaning “opened up” the flue. Corrine Halstead’s crew spots the telltale spiral scoring on camera. Repair is partial reline with matching SW sections, not a full tear-out - we write the scope to what’s actually damaged.
- DuraFlex 30° and 45° elbow sets: The gaskets harden faster than straight pipe, especially where a West Chester basement installation runs through damp foundation walls. CO readings creep up before there’s any visible problem. We pressure-test the elbow assembly, replace gaskets with DuraFlex-spec silicone, and log baseline CO readings under Haven Standard Clause 4.
- DuraFlex tee connectors (wood-burning installations):strong> The cleanout tee base collects acidic condensate in shoulder seasons when flue temps stay low. In West Chester, that’s most of October and April. Stainless tees pit through from the bottom up. We inspect with a borescope through the cleanout door, replace with 304 or 316Ti per the existing spec, and note material grade on your written record so the next tech knows what they’re working with.
Our DuraFlex Fireplace Services Process

- 1
Call and schedule. A live person answers, 24/7. We book a window, text your assigned tech’s name and photo, and send an “en route” text day-of.
- 2
NFPA 211 Level 2 inspection with camera. We run a chimney camera before quoting. For DuraFlex systems, we document liner wall condition, connection integrity, and any deviation from DuraFlex’s published installation tolerances. The camera doesn’t negotiate - it just shows you what’s there.
- 3
Written price, written scope, written warranty. Haven Standard Clause 1: you get all three before work starts. If we find a DuraFlex part that’s failed under warranty, we flag it so you can pursue OEM coverage while we handle the labor.
- 4
Parts decision: OEM or quality aftermarket. We stock DuraFlex-compatible components through our Haven buying network. For warranty-registered liners, we use OEM collars and adapters. For out-of-warranty systems, we may propose HeatShield or Gelco equivalents where they meet or exceed DuraFlex spec - priced honestly, with the trade-offs explained.
- 5
Repair, test, and document. We complete the work, run combustion analysis or draft testing as applicable, and upload photos plus readings to your record. Clause 4 of the Haven Standard requires this documentation on every job.
- 6
365-Day Done Right Promise. If anything in our scope fails, we make it right. No charge for our callback labor, no argument about whose fault it was.

AfterWhat DuraFlex Fireplace Services Costs in West Chester
These are real ranges for DuraFlex fireplace work we’ve performed in West Chester and Chester County:
- Gas fireplace service (DuraFlex Pro venting): $180-$280. Includes camera inspection of vent run, burner and pilot cleaning, gasket check, and combustion analysis.
- DuraFlex liner collar reseat or adapter replacement: $340-$520. Price depends on access (roof vs. interior) and whether we need to drop the insert.
- Firebox repair with DuraFlex-compatible refractory panels: $680-$1,200. Varies with panel count and whether the existing steel frame is square.
- Partial DuraFlex SW reline (delamination repair): $1,400-$2,600. Based on linear feet, number of offsets, and whether the original top plate can be reused.
- Fireplace conversion to DuraFlex insert with full liner: $3,200-$5,800. Includes removal of old firebrick, insert placement, liner down-and-connect, and NFPA 211 Level 2 final inspection with photo record.
What moves the price: access difficulty, parts availability (some DuraFlex SS adapters are 2-week order items), and whether we find secondary damage the camera reveals. Nothing gets added to the written scope without your approval. Call (610) 321-4570 for an exact quote - estimates are free.
Why West Chester Homeowners Call Level Two Chimney West Chester for DuraFlex Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, every one with a written price first and a documented record at completion. Our West Chester crew knows DuraFlex product lines from hands-on work in local homes - colonials near Everhart Park with original clay flues converted to DuraFlex inserts, Greystone townhomes with Pro venting runs that sag in crawl spaces, 1980s splits in West Goshen where SW liners were retrofitted after a chimney fire.
We’re not a DuraFlex dealer. We’re an independent DuraFlex service provider with buying relationships through DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. That matters when your part is back-ordered or when a quality equivalent saves you money without cutting safety. Our technicians are background-checked, uniformed, and named before they arrive. The 365-Day Done Right Promise covers every job. And if another company handed you a scary estimate, bring it - our Free Second Opinion costs nothing.
FAQs
No, if the work is performed by a qualified technician using DuraFlex-specified parts and methods. We document material grades and installation tolerances on every job so your warranty record stays clean. If we find a defect that should be covered by DuraFlex’s 20-year liner warranty, we flag it in writing so you can file the claim. Call (610) 321-4570 if you need help navigating the warranty process.
Most common DuraFlex SS and Pro fittings are 3-5 business days through our Haven buying network. Some 316Ti specialty adapters or custom-length SW sections run 10-14 days. We don’t start work until parts are in hand, and we don’t charge storage or delay fees. If your fireplace is unsafe to use, we’ll say so plainly and help you plan around the lead time.
Replace when the liner wall thickness has degraded below DuraFlex’s published minimum, when multiple offset sections are damaged (making partial repair uneconomical), or when you’re converting fuel types and the existing system isn’t rated for it. Repair when the failure is isolated to a collar, tee, or short section. We make the call based on camera evidence, not sales pressure, and we’ll show you the footage so you understand why. Call (610) 321-4570 for a camera inspection and written scope.
NFPA 211 recommends annual inspection for all chimney systems, including DuraFlex. For wood-burning installations in West Chester, where oak and hickory are common and burn hot but creosote-heavy, we often find Class II or III creosote buildup by month 10. Gas DuraFlex Pro venting can go longer between cleanings, but the combustion analysis and gasket check are still yearly items. We don’t upsell frequency - we show you the creosote class and let the camera dictate the interval.
For wood-burning: creosote accumulates, liner temperatures rise, and you risk a chimney fire that can warp or crack even 316Ti stainless. For gas: deteriorated gaskets or separated vent joints can leak carbon monoxide into living space. The camera finds both problems before they’re emergencies. Skipping service doesn’t save money - it shifts risk to your insurance deductible and your family’s safety. Call (610) 321-4570 to book an inspection; estimates are free.
