This page is for Ewing homeowners who know they have a DuraFlex liner, insert, or chimney system and want a technician who understands the difference between a DuraFlex 316Ti gas liner and a DuraFlex 304 alloy wood-burning application - not someone who treats every metal flue the same. If your fireplace is burning unevenly, your insert is drafting poorly, or you’re converting from wood to gas and need to know whether your existing DuraFlex liner will pass inspection, call us at (856) 388-5580. We’ll give you a free estimate and a plain-English verdict you can use, even if you don’t hire us.

How DuraFlex Products Fail - and How We Fix Them

• DuraFlex 316Ti gas fireplace liners: weld-seam corrosion at the termination cap. The 316Ti titanium-stabilized alloy resists acid corrosion well, but the longitudinal weld seam at the cap joint is a known weak point in Ewing’s climate. We get freeze-thaw cycles that pool condensation at the top, and after eight to twelve years that seam can weep or split. We replace with OEM DuraFlex termination components or, when the homeowner prefers, a quality aftermarket cap with a fully seamless collar - always with a camera inspection first so you see the damage yourself.
• DuraFlex 304 stainless wood-burning liners: creosote bridging at flex joints. The 304 alloy is cost-effective for wood-burning applications, but the corrugations that make DuraFlex flexible also create ledges where glazed creosote builds up - especially in Ewing’s older homes with slower-drafting fireplaces near the Delaware River floodplain, where humidity runs higher. We use rotary polypropylene whips sized to the liner diameter, not generic brushes that can catch and damage the flex walls. If the creosote is stage-three glazed, we’ll tell you straight: chemical treatment first, mechanical cleaning second, or the liner pays the price.
• DuraFlex DSA (Direct Vent Appliance) connectors: gasket deterioration on fireplace inserts. The DSA series uses a proprietary compression gasket at the appliance collar that hardens after five to seven years of cycling heat. Homeowners notice it first as a faint exhaust odor or a pilot that won’t stay lit in wind. We’ve learned to stock the DSA gasket kit because suppliers often treat it as special-order; most Ewing hardware stores don’t carry it, and a generic flat gasket won’t seal the oval profile correctly. We replace the gasket, test draft pressure with a manometer, and document the reading.
• DuraFlex SL (Smooth Wall) liners: inner-wall delamination in high-BTU gas conversions. The SL’s smooth inner wall improves draft, but the bonded laminate can separate near the first elbow in gas fireplace conversions where the appliance runs at sustained high output. We catch this with our Level-2 camera inspection - you’ll see the bubble or ripple on the monitor - and we don’t recommend a patch. The fix is a section replacement with proper DuraFlex SL coupling, sized to the appliance BTU rating per NFPA 211. We’ve seen two “budget” conversions in Ewing where the previous installer left a 304 flex in a 75,000-BTU gas application; both needed full relining within three years.
• DuraFlex transition plates: galvanic corrosion where dissimilar metals meet. DuraFlex systems often terminate through a galvanized or aluminum transition plate at the firebox or thimble. When the stainless flex contacts the plate directly, moisture wicks in and the plate corrodes from the inside - a problem we see more in Ewing’s spring and fall, when temperature swings drive condensation. We isolate the metals with a dielectric sleeve or replace the plate with a stainless transition, depending on what the camera shows. Russell Haines has sketched enough of these configurations over the years that our crew recognizes the pattern before the ladder goes up.

Our DuraFlex Fireplace Services Process

1. 1
   Call and schedule. A live person answers, 24 hours a day. We ask for your fireplace type, fuel, approximate age, and what you’re noticing. We quote the $89 Seasonal Tune-Up or schedule a diagnostic visit with no-hassle upfront pricing.
2. 2
   Level-2 camera inspection. Our technician arrives in uniform, background-checked, with a digital chimney camera. We document the full flue, firebox, damper, and termination. You see the photos; we give you a plain-English verdict on the spot.
3. 3
   Parts decision. If your DuraFlex component needs replacement, we explain OEM versus quality aftermarket options. OEM preserves any remaining warranty and guarantees alloy match; quality aftermarket saves money when warranty has expired and the part meets the same spec. You choose. No surprises on the bill.
4. 4
   The repair. Most DuraFlex fireplace services - damper adjustment, gasket replacement, insert service, firebox repair - we complete in a single visit. Relining or conversion work may need a second day; we tell you before we start.
5. 5
   Testing and documentation. We pressure-test gas connections, verify draft with a manometer, and run the fireplace through a full cycle. You get photos, the written report, and our 90-Day Done Right Promise in writing.
6. 6
   Cleanup and follow-up. We leave the work area as we found it. If anything isn’t right, we come back. No paperwork, no arguing.

Why Ewing Homeowners Call Hearthstone Chimney Co. for DuraFlex Work

We’ve been answering the phone with a live person for over 42 years, and we’ve cleaned and inspected chimneys throughout Ewing - including older homes near the Ewing-Lawrence border along Bear Tavern Road - long enough that some of those customers now have their children calling us before the cold sets in. We’re not a price-cutting chain, and we’re not a one-truck operator who might answer next week. We’re a company that plans to be in town in thirty more years, so we act accordingly.

Our technicians are background-checked, uniformed, and trained on DuraFlex specifically - the 316Ti alloy behavior, the SL inner-wall construction, the DSA gasket profiles. When a DuraFlex part isn’t the right fix, we also work with HeatShield for refractory restoration and Gelco for caps and accessories, so we’re not pushing a single product line. Every inspection ends with photos you can see and a plain-English verdict. Every job carries the 90-Day Done Right Promise: in writing, no arguing. If the flue is right, the fire takes care of itself.
