Call (833) 974-6113

This page is for Jacksonville homeowners who know they have a DuraFlex product in their fireplace system - whether a factory-built gas insert, a wood-burning zero-clearance unit, or a DuraFlex SS chimney liner paired with an existing hearth - and need service from someone who understands how these systems differ from generic builder-grade units. If you are in Ortega, San Marco, Riverside, or anywhere in Duval County, call (833) 974-6113. A live person answers, 24 hours a day.

How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SS liners crack at the flex-to-rigid transition in salt-air exposure. Jacksonville’s coastal humidity accelerates corrosion where the flexible stainless section meets the rigid tee. We see this most in homes east of the Intracoastal, especially in Atlantic Beach and Neptune Beach installations from the early 2000s. We cut back to sound metal, install a new DuraFlex SS transition piece with high-temp sealant rated for marine environments, and pressure-test before we leave.
• DuraFlex 316Ti gas inserts develop burner port clogging from pine pollen. Our heavy spring pollen season - March through May - sends fine yellow dust into every vented opening. On DuraFlex 316Ti inserts, it bakes onto burner ports and causes uneven flame or delayed ignition. We disassemble the burner tray, clean each port with a brass pick (never a wire brush, which scores the soft metal), and verify flame pattern against the factory spec sheet.
• DuraFlex factory-built wood units show refractory panel spalling after freeze-thaw cycles. Jacksonville’s occasional hard freeze - once or twice most winters - shocks the refractory panels in DuraFlex wood-burning zero-clearance units. The panels look intact but shed thin flakes that clog the smoke shelf. We replace with OEM DuraFlex refractory panels or, when backordered, HeatShield-certified refractory coating if the substrate allows. Dale Brinson checks the smoke shelf personally on these jobs - he’s found too many near-fires from accumulated spall debris.
• DuraFlex damper assemblies seize from disuse in converted gas units. Homeowners who converted from wood to gas often stop operating the damper, and the DuraFlex cast-aluminum damper frame corrodes in place. We never force it. We remove the damper plate, clean the frame with a nylon brush and penetrating solvent, lubricate with high-temp graphite, and test ten open-close cycles. If the frame is cracked - common on pre-2010 units - we source the exact DuraFlex damper kit rather than modifying a generic part.
• DuraFlex chimney caps lose mesh tension and admit wildlife. The factory mesh on older DuraFlex caps relaxes after years of thermal cycling. Squirrels in Mandarin, raccoons in Avondale - we have pulled nests from both. We measure the flue collar precisely and install a Gelco or Famco cap with stainless mesh in the correct gauge for DuraFlex flue dimensions, not a universal clamp-on that gaps in six months.

Our DuraFlex Fireplace Services Process

1. 1
   Call intake with live person. We ask for the DuraFlex model number from the data plate - usually inside the firebox or on the exterior chase - so our technician pulls the correct documentation before arriving.
2. 2
   Level-2 camera inspection. We run a chimney camera to document flue condition, liner integrity, and any obstruction. You see the photos. We give you a plain-English verdict on what is wrong, what it costs, and what happens if you wait.
3. 3
   Parts decision: OEM DuraFlex or verified equivalent. We stock common DuraFlex gas valves, igniters, and damper kits. For discontinued lines, we source quality aftermarket from our HeatShield, Gelco, or Copperfield inventory - never builder-grade substitutes - and we tell you before we order.
4. 4
   Repair with no-hassle upfront pricing. The number on the estimate is the number on the invoice. Our background-checked, uniformed technician completes most DuraFlex repairs in one visit.
5. 5
   Post-repair combustion test and safety check. For gas units, we test CO levels at the appliance and in the room, verify draft with a manometer, and check all safety shutoffs. For wood units, we verify liner draft and smoke chamber flow.
6. 6
   Written guarantee and cleanup. We leave you with the 90-Day Done Right Promise in writing - no paperwork to mail, no arguing. If it is not right, we come back. We vacuum the hearth area with our own equipment; you should not know we were there except that the fireplace works.
