How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SS (stainless venting) - creosote bridging in hillside Los Angeles installations. The SS line’s smooth-wall design resists buildup, but we’ve found that homes above 1,200 feet in the Foothills, where nighttime temperatures drop 15 degrees cooler than the Basin floor, develop accelerated condensation at the vent termination. That moisture binds with fine particulate into a hard, glassy bridge that chokes draft. We remove it with rotary whipping, inspect the cap for proper overhang, and adjust the termination height if wind patterns are contributing.
- DuraFlex SW (smooth wall) - blower motor bearing fatigue in gas inserts. The SW series uses a sealed blower assembly that’s quiet when new, but after eight to ten years of cycling through Los Angeles winter evenings, the bearings dry out and start a low whine that climbs to a rattle. We’ve learned the OEM motor runs about $340, but a quality aftermarket equivalent with the same CFM rating and thermal cutoff spec performs identically for roughly $180 less. We source both, explain the difference, and let the homeowner choose.
- DuraFlex AL (aluminum) - firebox refractory cracking in wood-burning units. The AL line’s lighter refractory panels save shipping weight, but they don’t tolerate thermal shock as well as denser materials. In older Los Angeles homes with original masonry hearths retrofitted for AL inserts, we’ve seen hairline cracks propagate after a single overfiring episode, often from pine or eucalyptus that burns hotter than the oak the unit was rated for. We replace with factory panels when available, or fabricate custom refractory shapes for discontinued models.
- DuraFlex Pro - gas valve slow-leak causing intermittent ignition failure. The Pro series uses a SIT 820 valve that’s reliable but sensitive to gas pressure fluctuation, which is common in Los Angeles neighborhoods with aging utility infrastructure. A valve that tests fine at 10 AM can drop below minimum manifold pressure during evening demand spikes. We test under load, replace with a valve rated for your local gas composition, and document baseline pressure so the next tech has a reference point.
- DuraFlex termination caps - wind-driven rain infiltration in coastal zones. Standard DuraFlex caps with single baffles work fine inland, but in Santa Monica, Venice, and San Pedro, we’ve documented repeated water intrusion during Santa Ana wind events that pressurize the flue. The fix isn’t a bigger cap, it’s a specific storm collar assembly with a drip edge that sheds water before it reaches the flue joint. We keep three sizes on the truck.
Our DuraFlex Fireplace Services Process
- 1
Call intake with a live person. When you reach us at (844) 418-0954, we ask for the DuraFlex model number (usually on a metal tag inside the lower access panel), the symptom, and how long it’s been happening. This lets our tech pull the right manual before leaving the shop.
- 2
Level-2 camera inspection with photos you can see. We run a chimney camera to document flue condition, check for liner displacement, and look for the specific failure patterns each DuraFlex series is known for. You get the photos and a plain-English verdict before we quote.
- 3
Parts decision: OEM, quality aftermarket, or fabrication. If your unit is current production, we quote factory parts with full warranty. For discontinued lines, we source from our network or fabricate in-house. You’ll know the origin of every part and why we chose it.
- 4
Repair with no-hassle upfront pricing. The number on the estimate is the number on the invoice. We complete most DuraFlex repairs in a single visit because our trucks carry the common failures.
- 5
Combustion test and safety verification. Gas units get a full combustion analysis with CO and O2 readings logged. Wood units get a draft test at operating temperature. We don’t leave until the numbers are right.
- 6
Written guarantee and cleanup. Every job carries our 90-Day Done Right Promise, in writing, no arguing. If it’s not right, we come back. We leave the work area cleaner than we found it.

Why Los Angeles Homeowners Call Hearthstone Chimney Co. of Los Angeles for DuraFlex Work
We’ve been working chimneys across Los Angeles since 1984 - from the original Craftsman bungalows in Eagle Rock to the hillside contemporaries in the Foothills. Gil Mercer, our owner, learned this trade at Los Angeles Trade-Technical College and spent twenty years in the field before building Hearthstone into what it is now. The chimney doesn’t lie. Neither do I. That’s not a slogan; it’s how we operate.
Our 90-Day Done Right Promise means if we miss something, we make it right - in writing, no arguing, no paperwork chase. Our technicians are background-checked, uniformed, and trained on DuraFlex specifics, not generic fireplace theory. When a DuraFlex part is back-ordered or discontinued, we don’t leave you hanging; we work with HeatShield refractory systems and Gelco termination hardware to engineer a solution that meets or exceeds original spec. And a live person answers the phone, 24 hours a day, because a cold house at 6 AM doesn’t wait for business hours.
FAQs
No - manufacturer warranties cover defects in materials and workmanship, not who performs routine service or repair. We document every part and procedure, so if a factory defect surfaces later, you have the paperwork to support a claim. Call (844) 418-0954 if you’d like us to review your warranty status before we begin.
For current-production DuraFlex lines, we typically receive OEM parts within two to three business days from regional distribution. For discontinued series, we maintain a salvage network and fabrication capability that often beats factory lead times. Most common failures - blower motors, gas valves, refractory panels - we carry on the truck and can install same-day.
If your DuraFlex is under twelve years old and the firebox is sound, repair is almost always the better value; we’ve brought thirty-year-old units back to safe operation with targeted work. If the heat exchanger is cracked, the unit is obsolete, or repair costs exceed 60% of replacement, we’ll tell you plainly and help you size a new system. Our free second opinion applies to any written replacement estimate you’ve received.
Yes, for most AL and SS venting configurations, we can install a listed gas insert or log set that mates with your existing DuraFlex flue. The critical factor is flue diameter and liner compatibility; we verify both during our inspection. Conversions require a permit in Los Angeles, which we handle as part of the job. Call for a free estimate.
We offer a permanent 5% discount for seniors and veterans, applied to any repair or service. Our $89 Seasonal Tune-Up applies to DuraFlex units same as any other, and repairs over $250 qualify for $50 off. We don’t stack promotions, but we’ll apply whichever saves you more.
