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 steel liner) - creosote bridging at the flex joints. The corrugations that make SW adaptable to offset flues also create ledges where glazed creosote builds, especially in Collegeville’s hard-water zone where homeowners burn seasoned oak from Berks County. We camera-scan to locate the bridge, mechanically remove it without damaging the flex wall, and document the liner’s remaining wall thickness. If the creosote has masked thinning metal, we show you the footage before quoting replacement.
- DuraFlex AL (aluminum liner) - heat-shield separation in gas fireplace inserts. The AL’s lighter gauge works for Category I gas appliances, but the factory insulation blanket can sag after 8-12 years of thermal cycling, creating a hot spot that trips the high-limit switch. We find the gap with a borescope, source the correct DuraFlex-compatible insulation kit or a Gelco alternative if the OEM part is back-ordered, and reinstall to manufacturer clearances.
- DuraFlex Pro - tee-body corrosion at the cleanout. The Pro’s heavier construction holds up well, but the tee body where the liner meets the thimble collects acidic condensate in shoulder-season burns, particularly when Collegeville homeowners start fires in October before sustained cold sets in. We pull the tee, assess pitting depth with a pit gauge, and replace with a stainless tee from Olympia Chimney or a DuraFlex OEM part depending on availability and your preference.
- DuraFlex relining transitions - masonry firebox spalling behind the adapter plate. When a DuraFlex liner is retrofitted into an older Collegeville colonial, the adapter plate can trap moisture against the rear firebox wall. We see this on Main Street homes built 1920-1950. Our fix removes the plate, repairs the spalled brick with HeatShield Cerfractory Foam, and reinstalls with a proper thermal break so the problem doesn’t repeat.
- DuraFlex gas insert venting - induced draft motor failure in direct-vent units. The FMI-branded direct-vent inserts that ship with DuraFlex vent kits use a specific motor curve that aftermarket replacements sometimes mismatch. We test amp draw and static pressure before ordering, source the correct OEM or a verified cross-reference from Famco, and verify combustion analysis before leaving.
Our DuraFlex Fireplace Services Process

- 1
Call and schedule. A live person answers, checks DuraFlex part availability for your model series, and books a diagnostic window. You’ll get a text when your tech is en route.
- 2
Camera-scan inspection. We run a Level 2 inspection per NFPA 211, camera down the flue or borescope into the firebox, depending on the failure mode. Corrine Halstead trained at New York City College of Technology to read a flue systematically, and her crew applies that same discipline to every Collegeville job.
- 3
Written price, written scope. Before any tool touches your system, you receive a written price, a written scope of work, and a written warranty. Clause 1 of the Haven Standard requires it. The camera doesn’t lie, and neither does the written price.
- 4
Parts decision with options. We stock common DuraFlex consumables and source OEM or quality aftermarket parts through Haven’s buying network. If a Gelco or Olympia Chimney equivalent meets spec and saves you money without voiding remaining warranty coverage, we explain the trade-off.
- 5
Repair, test, document. We complete the work, run combustion analysis or a smoke-pencil draft test as appropriate, and add the photo record to your file. Haven Standard Clause 4 requires this documentation.
- 6
365-Day Done Right Promise. If it’s not done right, we make it right. The promise is stamped on every job.

Why Collegeville Homeowners Call Emberly Chimney Cleaners Collegeville for DuraFlex Work

We’ve 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 assigned by name, with license information displayed on every page. We source DuraFlex, HeatShield, Gelco, and Olympia Chimney materials through Haven’s buying network to keep customer prices honest, not inflated by middlemen.
Collegeville’s freeze-thaw cycles and the oak-heavy burn habits in this part of Montgomery County create specific wear patterns we’ve documented across hundreds of local jobs. We know which DuraFlex tee bodies pit fastest here, which adapter plates trap moisture in 1920s fireboxes, and how to fix both without selling you a full relining you don’t need. If the camera shows it can wait, we say so. If it can’t, we show you why.
FAQs
No, as long as we use OEM or equivalent-spec parts and document the work. We’re an independent DuraFlex service provider, not a dealer, and we follow manufacturer installation and repair standards. Our photo record protects you if a warranty question ever arises. Call (610) 884-0366 for a free estimate.
Common DuraFlex consumables - tee bodies, adapters, termination caps - are usually in stock or available within 3-5 business days through Haven’s buying network. Back-ordered OEM items can stretch to 10-14 days; we always quote a quality aftermarket alternative (Gelco, Olympia Chimney, Famco) if the delay affects safety or heating season timing. Call (610) 884-0366 to check current availability for your model.
Replace when the camera shows wall thinning below 20 mil in stainless, or when multiple joint failures indicate systemic fatigue. Repair when damage is localized - one bad tee, a separated heat shield, a cracked adapter - and the remaining liner passes gauge inspection. We show you the footage and the price for both paths before you decide. Call (610) 884-0366 for a free camera inspection.
NFPA 211 recommends annual inspection for all chimney systems, including DuraFlex liners and inserts. In Collegeville, we find that wood-burning DuraFlex SW liners used as primary heat sources benefit from mid-season checks due to heavy creosote formation in the flex joints. Gas DuraFlex AL systems can often go annual unless you notice odor, sooting, or ignition delay. Call (610) 884-0366 to schedule.
Delayed ignition, incomplete combustion, and carbon monoxide spillage are the real risks. The DuraFlex AL’s lighter construction depends on proper draft and clean burner orifices; neglect allows debris accumulation that alters the fuel-air ratio. We test CO levels and combustion efficiency on every service visit, and we document the readings. If the numbers are off, we show you and fix it. Call (610) 884-0366 for a free estimate.
