Call (877) 565-7563

This page is for Orlando homeowners who know they’ve got DuraFlex in their flue, or suspect it, and need straight answers on whether it can be repaired or needs replacement. We’ve worked on DuraFlex systems in College Park bungalows, Winter Park ranch homes, and downtown Orlando townhouses since 2014. If you’re seeing water in the firebox, smelling smoke in rooms upstairs, or pulling chunks of liner material out with your poker, call us at (877) 565-7563. A live person answers, day or night.

How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW (stainless wrap) liner separation at the tee. In Orlando’s humidity cycle, the SW’s outer wrap can trap condensation where the tee body meets the flex section. We see this most in homes near Lake Apopka and the Conway chain, where afternoon storms spike indoor humidity. Our fix: cut back to sound metal, install a factory DuraFlex tee with proper condensate drainage, and verify with a Level-2 camera pull before we button it up.
• DuraFlex Pro liner crevice corrosion at the crown interface. The Pro’s heavier gauge holds up well, but the termination point is where Florida rain does its damage. When the crown seal fails, water tracks down between the liner and clay flue tiles, eating the Pro’s outer wall from the outside in. We rebuild the crown with proper slope and drip edge, then re-terminate the liner with a Gelco or Famco cap sized to the Pro’s outer diameter, not a generic clamp-on.
• DuraFlex AL (aluminum) heat distortion in converted gas inserts. Orlando’s 1970s and 80s ranch homes often have AL liners from original wood-to-gas conversions. The AL was never rated for the sustained temperatures of modern direct-vent inserts. We pull the damaged AL, verify the flue sizing for the new appliance, and install DuraFlex SW or a rigid Olympia Chimney stainless system depending on the run.
• DuraFlex flexible liner support failure in tall Orlando chimneys. The flexible winding can sag in chimneys over 25 feet, especially where Orlando’s soft mortar lets the clay tiles shift slightly over decades. We find the sag with a camera, install a proper support plate at the top and a mid-point support if needed, and in some cases switch to a rigid DuraFlex or Olympia Chimney liner for the straight vertical runs.
• DuraFlex connector stub deterioration on exterior chimneys. Orlando’s afternoon thunderstorms and UV exposure attack the short stainless connector between liner and appliance. On homes in Baldwin Park and Audubon Park, we’ve replaced dozens of these stubs with heavier-gauge DuraFlex SW connectors or custom-fabricated Copperfield transitions that outlast the original.

Our DuraFlex Chimney Liner & Rebuild Process

1. 1
   Call and schedule. A live person answers at (877) 565-7563, 24 hours a day. We book your Level-2 inspection, usually within a day.
2. 2
   Camera inspection and documentation. Our technician runs a high-res camera through the full length of your DuraFlex liner. You see the photos. We give you a plain-English verdict: repair, replace, or rebuild. Roy Dempsey’s standard applies here - we’ll tell you if it just needs cleaning, and we won’t confuse that with real work.
3. 3
   Parts decision: OEM DuraFlex or quality aftermarket. If DuraFlex factory parts are available and appropriate, we quote them. If a HeatShield cerfractory repair, Gelco cap, or Olympia Chimney rigid section solves the problem better or faster, we explain why and let you choose. No brand loyalty that isn’t earned.
4. 4
   The repair. Our background-checked, uniformed technician arrives with materials in hand. Most DuraFlex liner replacements and rebuilds finish in one visit. We protect your floors, work clean, and keep you posted.
5. 5
   Post-repair testing. We run another camera pull, a smoke test, or a draft test depending on the job. You see the after photos. The flue either passes or we keep working.
6. 6
   Written guarantee and cleanup. The 90-Day Done Right Promise goes in your hand before we leave. In writing, no arguing. If it’s not right, we come back. A clean chimney is not a luxury - it is just the job done right.

What DuraFlex Chimney Liner & Rebuild Costs in Orlando

These are real numbers for the Orlando market, based on jobs we’ve completed in neighborhoods from Thornton Park to Dr. Phillips:

What moves the price: chimney height, roof pitch and access, whether we need to remove an insert or stove to access the flue, and the condition of the clay tiles surrounding the liner. Orlando’s older homes in College Park and Delaney Park often have offset flues or tight fireboxes that add labor. We give you the full number before we start.
