DuraFlex Chimney Repair in Orlando: What to Know First
We provide independent DuraFlex chimney repair in Orlando, and most jobs are completed in a single visit with upfront pricing that does not change on the invoice. A straightforward mortar repointing on a DuraFlex-lined flue typically runs $280-$450, while a full chimney rebuild with DuraFlex liner replacement can reach $3,200-$5,800 depending on height and access. Roy Dempsey and our team have worked on DuraFlex systems across College Park, Winter Park, and the older lakefront homes near Conway for over 42 years, and we answer the phone with a live person 24 hours a day at (877) 565-7563. This page is for homeowners who know they have a DuraFlex product and need honest answers about what is actually wrong and what it will cost to fix it right.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (Stainless Wall) liners in Orlando’s hard-water zones. The SW series uses a 316Ti stainless inner wall that holds up well to creosote, but we see premature outer-wall corrosion in homes east of Semoran Boulevard where irrigation and afternoon thunderstorms keep masonry saturated for months. The liner does not fail from the inside out; it fails from the outside in, where trapped moisture cannot escape. We pull the damaged section, inspect the full run with our Level-2 camera, and replace only what is necessary using OEM DuraFlex couplers so the warranty stays intact.
- DuraFlex AL (Aluminum) liners in gas-venting applications with spalling brick above the roofline. The AL series is rated for gas only, but we find it installed in Orlando homes where a previous owner converted from wood to gas without addressing the exterior masonry. Spalling brick dumps debris onto the aluminum collar, and the AL liner is not built to take impact. We repair the spalling with a color-matched mortar, install a Gelco or Famco cap with proper overhang, and replace the damaged AL section with new DuraFlex AL - never substituting stainless, which changes the venting dynamics.
- DuraFlex Pro and Pro-HT liners with failed top plates in high-wind corridors. The Pro series uses a heavier-gauge inner wall, but the standard top plate sealant can dry-crack after three to four years of Central Florida UV exposure, particularly in open neighborhoods near Lake Apopka where afternoon storms drive rain sideways. Water enters, pools in the annular space, and the homeowner smells musty combustion gases. We replace the top plate with a DuraFlex OEM unit, reseal with high-temp silicone rated for Florida sun, and document the repair with photos the owner can keep.
- DuraFlex relining jobs where the original installer skipped the insulation wrap. NFPA 211 requires insulation on most liner installs, but we find uninsulated DuraFlex runs in pre-1990 Orlando ranch homes where a handyman cut corners. Without insulation, the liner runs cooler, creosote condenses faster, and the terra cotta flue continues to deteriorate around it. We do not leave it that way. We pull the liner, install proper DuraFlex insulation mix or a listed wrap system, and reline to code - done right, and we stand behind it.
- DuraFlex tee connectors in two-story Winter Park colonials with offset flues. The DuraFlex tee is a well-made part, but the flexible section above it can kink in tight offsets common in 1920s Orlando-area construction. A kinked tee restricts draft, causes smoking into the room, and strains the connection at the thimble. We use a DuraFlex rigid tee with a custom-fabricated offset section when the geometry demands it, or we reconfigure the flue path with an insulated DuraFlex Pro run. Either way, the tee is accessible for future cleaning, which matters to us because a clean chimney is not a luxury - it is just the job done right.
Our DuraFlex Chimney Repair Process
- 1
Live answer, scheduled arrival. A real person takes your call at (877) 565-7563, and we book a window we intend to keep. We’ll be there when we say.
- 2
Level-2 camera inspection with photos you can see. Our technician runs a chimney camera the full length of your DuraFlex liner and the surrounding masonry. You see what we see, and we explain it in plain English - documented like an engineer, explained like a craftsman.
- 3
Parts decision: OEM DuraFlex or quality equivalent. We stock common DuraFlex components, and when a proprietary part is back-ordered, we source quality aftermarket from our Copperfield and Olympia Chimney supply lines that meets or exceeds OEM spec. We tell you which we are using and why, and we never substitute without your knowledge.
- 4
The repair, completed in one visit when possible. Our background-checked, uniformed technicians carry the tools and materials to complete most DuraFlex repairs without a return trip. No-hassle upfront pricing means the number on the estimate is the number on the invoice.
- 5
Post-repair draft test and documentation. We fire the appliance, verify draft and spillage with a manometer, and photograph the completed work. You receive a written report with the 90-Day Done Right Promise - in writing, no arguing.
- 6
Cleanup and walkthrough. We leave the work area as we found it, explain what was done, and answer any questions before we go. A square deal: no surprises on the bill.
What DuraFlex Chimney Repair Costs in Orlando
| Repair Scenario | Typical Range |
|---|---|
| Mortar repointing, DuraFlex liner intact (up to 15 sq ft) | $280 - $450 |
| Spalling brick repair with DuraFlex AL collar replacement | $650 - $1,100 |
| DuraFlex SW liner section replacement (single story) | $1,200 - $1,800 |
| Full DuraFlex relining with insulation (two-story) | $2,400 - $3,600 |
| Chimney rebuild with DuraFlex liner replacement | $3,200 - $5,800 |
Three factors move these numbers: height and roof access, whether the DuraFlex liner can be saved or must be replaced, and the extent of water damage to surrounding masonry. Homes in Orlando’s older neighborhoods like College Park or Delaney Park often have tighter clearances and harder mortar, which adds labor but does not change our upfront price once we quote it. Call (877) 565-7563 for an exact quote - estimates are free.

FAQs
No, provided the repair uses DuraFlex OEM parts or listed equivalents installed to NFPA 211 standards. As an independent DuraFlex service provider, we follow the manufacturer’s installation guidelines precisely and document our work so any future warranty claim has the paperwork it needs. Call (877) 565-7563 if you have questions about your specific liner model.
We stock common DuraFlex couplers, tees, and top plates at our Orlando warehouse, and most standard repairs need no waiting. For specialty Pro-HT components or custom lengths, our supply chain through Copperfield and Olympia Chimney typically delivers within two to three business days. If your chimney is unsafe to use, we will explain your options and prioritize the fastest safe path.
Repair is almost always cheaper, and we will tell you straight when it is not. A localized DuraFlex liner repair runs $1,200-$1,800 versus $3,200-$5,800 for a full rebuild with liner replacement. We only recommend rebuild when the masonry structure is compromised or the liner damage exceeds what a targeted repair can safely address. Our free second opinion on any written estimate gives you confidence in the call.
We answer with a live person 24 hours a day, and we schedule most DuraFlex repairs within 24 to 48 hours. Emergency situations - a detached liner, visible exterior collapse, or carbon monoxide spillage - get same-day response. Call (877) 565-7563 to describe what you are seeing, and we will tell you honestly whether it can wait or needs immediate attention.
Yes. We service and repair HeatShield, Gelco, Olympia Chimney, and other professional-grade systems, and our technicians carry the tools and training to diagnose across brands. Many Orlando homes have mixed systems - a DuraFlex liner with a Gelco cap, for instance - and we repair the whole assembly without forcing a single-brand solution that does not fit your chimney.
