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 Pro liners with seam separation at the flex joints. The Pro’s interlocked seam construction handles thermal expansion well, but after 15-20 years of Cherry Hill freeze-thaw cycles, the seam lips can work apart at stress points near the smoke chamber. We spot this with a Level-2 camera inspection, then sleeve or replace the affected section with matching DuraFlex Pro stock or a compatible aftermarket interlock - never forcing a rigid fix where flex belongs.
- DuraFlex SW (stainless wall) liners corroding from the outside in. The SW’s lighter wall thickness saves weight and cost, but in Cherry Hill’s older homes - especially the pre-1970s colonials in Barclay Farm and Kingston - we’ve seen exterior corrosion accelerate where the liner passes through a cool, damp exterior chase. The fix isn’t always full replacement. If the damage is localized above the roofline, we can splice in a DuraFlex SW replacement section; if it’s systemic, we upsize to a heavier DuraFlex Pro or recommend a HeatShield cerfractory resurfacing where the liner itself isn’t the weak point.
- DuraFlex gas insert venting with condensate backflow. The AL29-4C alloy in DuraFlex gas venting resists corrosive condensate, but improper slope or a missing drain tee lets acidic moisture pool at low points. In Cherry Hill’s split-level and raised-ranch stock, we’ve found installers who ran horizontal vent runs with insufficient pitch. We re-pitch to 1/4 inch per foot minimum, install proper drain fittings, and pressure-test the assembly - not just light the pilot and leave.
- DuraFlex damper adapters seizing after conversion jobs. When a wood-burning fireplace gets converted to gas logs or an insert, the original throat damper often gets locked open with a DuraFlex adapter plate. After years of disuse, the damper frame rusts into the adapter, making future service or re-conversion difficult. We cut the adapter free without damaging the DuraFlex liner termination, clean and assess the damper, and document whether it’s salvageable or needs replacement with a Gelco or Famco top-sealing damper.
- DuraFlex chimney cap and termination degradation. The factory termination on older DuraFlex installations uses a stamped collar that can fatigue at the crimp points. Cherry Hill’s nor’easter wind loads - particularly in exposed areas near the Croft Farm and Cherry Hill East - accelerate this. We replace with a DuraFlex-compatible termination or, where clearance allows, upgrade to a Gelco or Copperfield cap with a sturdier mounting band and proper storm collar.
Our DuraFlex Fireplace Services Process
- 1
Call and schedule. A live person answers, day or night. We ask the model if you know it, the symptoms, and the fireplace type. We quote a dispatch fee range and schedule a window.
- 2
Arrival and inspection. Our technician arrives in a marked truck, uniformed, background-checked. We lay down protection, then run a Level-2 camera inspection - photos you can see on the tablet, with a plain-English verdict.
- 3
Diagnosis and parts decision. We identify the DuraFlex series, assess whether OEM or quality aftermarket parts make sense, and explain the trade-offs. No parts ordered without your okay.
- 4
Repair with test. We complete the work, then test-fire and monitor - gas pressure checked, draft measured, visual inspection of flame pattern or wood-burning draw. The chimney either draws the way it should, or it does not - and we will not leave until we know which.
- 5
Documentation and guarantee. You get photos, the written report, and the 90-Day Done Right Promise in writing. If it’s not right, we make it right. No arguing, no paperwork chase.
- 6
Cleanup and close. We haul away old parts, vacuum the work area, and review the invoice - the number matches the estimate. You pay what we agreed.

Why Cherry Hill Homeowners Call Hearthstone Chimney Co. for DuraFlex Work
We’ve served Cherry Hill for years, including those older colonials over in Barclay Farm where the fireplaces run nearly as old as the subdivision itself. Russell Haines and our crew know DuraFlex products from hands-on work, not from a catalog - the Pro versus SW decision, the AL29-4C condensate quirks, the adapter compatibility issues that trip up less experienced techs. When DuraFlex isn’t the right solution, we have HeatShield and Gelco in our toolkit, not as upsells but as honest alternatives. The 90-Day Done Right Promise means if we miss something, we come back. In writing. No arguing. That’s how we’ve operated since 1984, and it’s why we plan to be here when your next question comes up.
FAQs
No - DuraFlex warranties cover manufacturing defects, not who performs the installation or service. As an independent DuraFlex service provider, we use OEM-spec parts and document our work so any legitimate warranty claim stays valid. Keep your paperwork organized, and call us at (856) 543-2929 if you need help with a claim.
Common DuraFlex Pro and SW sections, adapters, and terminations are usually in stock at our South Jersey suppliers within 2-3 business days. Specialty AL29-4C gas venting or oversized diameters may take 5-7 days. We order only after you approve the repair, and we don’t charge storage or rush fees we didn’t agree to upfront.
Replace if the damage exceeds 20-25% of the run length, if there are multiple failure points, or if the original SW thickness no longer meets your fuel type’s code requirements. Spot-repair if the damage is localized and accessible. We’ll show you the camera footage and give you both numbers so you can decide. Call (856) 543-2929 for a free estimate.
Yes, if the DuraFlex liner and surrounding structure pass inspection. We check liner compatibility with your chosen gas appliance, verify clearances to combustibles, and install proper venting or adapter assemblies. We do not perform conversions without a Level-2 inspection - the risk of improper draft or condensate damage is real, and we won’t sign off on guesswork.
Annually, before the heating season. Cherry Hill’s humidity swings and freeze-thaw cycles stress venting components more than milder climates. An $89 seasonal tune-up catches condensate drainage issues, burner sooting, and termination degradation before they become expensive problems. Call (856) 543-2929 to schedule - estimates are free.
