DuraFlex Chimney Cap & Crown in Orlando: What to Know First
We provide independent DuraFlex chimney cap and crown service in Orlando, with most DuraFlex cap replacements and crown repairs completed in a single visit. A standard DuraFlex cap installation runs $280-$520, while crown repair or coating typically falls between $340-$780 depending on flue count and access. We do not quote over the phone and then surprise you on the invoice, the number on the estimate is the number on the bill.
This page is for Orlando homeowners who already have a DuraFlex liner or cap system and need straight answers about what is failing, what it costs to fix, and who can do it without voiding what warranty remains. We are not DuraFlex authorized, we are an independent DuraFlex service provider with no ties to the manufacturer. If that sounds like your situation, call us at (877) 565-7563. A live person answers, 24 hours a day.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (stainless wall) caps: The 304-grade mesh on earlier SW series caps corrodes faster than expected in Orlando’s humidity, especially within three miles of any of the lakes. We see this in College Park and Winter Park regularly. The mesh opens up, squirrels and rain get in, and the liner collar starts to wick moisture down into the flue. We replace with either OEM DuraFlex mesh or a heavier 316-grade aftermarket equivalent, depending on what the homeowner prefers and what warranty status allows.
- DuraFlex Pro cap separation at the storm collar: The Pro series uses a two-piece storm collar that can gap after five to seven years of thermal cycling. Orlando’s afternoon thunderstorms hammer that gap. Water runs behind the cap, pools on the crown, and you get spalling concrete inside six months. We reseat with a proper high-temp sealant, not silicone, and add a drip edge if the original design lacked one.
- DuraFlex AL (aluminum) cap galvanic corrosion: The AL series is lighter and costs less, but when it is paired with a copper or galvanized chase cover from another manufacturer, galvanic corrosion eats the cap flange in two to four years. We see this in Baldwin Park townhomes where builders mixed brands. We replace the cap with a matched-material flange or switch the whole assembly to stainless if the budget allows.
- Crown wash failure under DuraFlex multi-flue caps: DuraFlex multi-flue caps are well-built, but they are heavy. If the original crown was poured thin, which is common in 1980s Orlando construction, the cap weight plus thermal expansion cracks the crown in a radial pattern. We do not just caulk over it. We grind back to sound concrete, pour a proper sloped crown with at least two inches at the thinnest point, and reset the cap on a bed of sealant with weep channels.
- DuraFlex telescoping cap lock-ring fatigue: The telescoping caps on taller Orlando chimneys, common in Lake Nona and Dr. Phillips where two-story construction dominates, rely on a stainless lock-ring that loosens over time. The cap drops a quarter inch, the storm collar no longer seats, and you get a whistle on windy days that the homeowner notices before the leak. We replace the lock-ring with a heavier-gauge aftermarket part or switch to a fixed-height cap if the flue is stable.
Our DuraFlex Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, day or night. We ask about your DuraFlex model if you know it, the age of the cap or crown, and what you are seeing. Water stains, animal noise, draft problems, or visible rust, each tells us something different.
- 2
Level-2 camera inspection on arrival. Our technician runs a camera down the flue before touching the cap. We document liner condition, crown integrity from below, and any moisture damage. You see the photos. We give you a plain-English verdict, no jargon.
- 3
Parts decision. If your DuraFlex cap is under ten years old and the warranty is intact, we source OEM. If the warranty has lapsed or the OEM part is back-ordered, we use professional-grade aftermarket from our standard inventory, Gelco or Famco equivalents that match or exceed DuraFlex specs. We explain the trade-off and you decide.
- 4
The repair. Cap replacement takes ninety minutes to two hours. Crown repair or coating takes three to four hours, longer if we need to rebuild. Our technicians are background-checked, uniformed, and carry everything on the truck. Most jobs finish in one visit.
- 5
Post-repair test and documentation. We run water simulation with a controlled spray to verify cap and crown integrity. We photo-document the finished work. You get a written report with the 90-Day Done Right Promise attached, no paperwork to mail in, no arguing if something is not right.
- 6
Cleanup and walk-through. We leave the roof and the hearth cleaner than we found them. You sign once, and the price matches the estimate.
What DuraFlex Chimney Cap & Crown Costs in Orlando
| Service | Typical Range | What Moves the Price |
|---|---|---|
| DuraFlex single-flue cap replacement | $280-$420 | Flue diameter, mesh grade (304 vs. 316), roof pitch |
| DuraFlex multi-flue cap replacement | $380-$520 | Flue count, chase dimensions, need for new base plate |
| Crown repair with DuraFlex cap reset | $340-$580 | Crown size, depth of spalling, need for mesh reinforcement |
| Crown coating (HeatShield Cerfractory Foam) | $420-$780 | Number of flues, crown condition, access difficulty |
| Telescoping cap lock-ring repair or conversion | $180-$290 | Height of chimney, need for scaffolding vs. ladder |
Orlando’s flat terrain helps with access, but the afternoon thunderstorms and near-constant humidity from June through October mean we do not skimp on sealant quality or crown slope. A cheap crown coating fails in eighteen months here. We have seen it. The price reflects doing it once, correctly.

Why Orlando Homeowners Call Hearthstone Chimney Co. of Orlando for DuraFlex Work
We have been answering the phone in Orlando for over 42 years. Roy Dempsey started this company in 1984 after two decades of hands-on chimney work across Central Florida, and we still operate by the same standard: tell the truth about what the chimney needs, do what you said you would do, and stand behind it.
The 90-Day Done Right Promise is not a slogan. It is in writing. If a DuraFlex cap we installed leaks, or a crown coating cracks, or a storm collar separates, we come back. No paperwork, no arguing. That is the Keystone Standard: Krafted right, Every time, Your home first, Standing behind it.
Our technicians know DuraFlex products specifically, not just chimneys in general. They also carry HeatShield and Gelco inventory, so if your DuraFlex system has a companion component from another brand, or if an aftermarket Gelco cap makes more sense than waiting for DuraFlex OEM, we can decide that on the spot. You do not wait two weeks for a part while water comes in.
A live person answers every call, 24 hours a day. Most jobs complete in one visit. And the estimate you receive is the invoice you pay.
FAQs
No, independent service does not automatically void a DuraFlex warranty, but using non-OEM parts on a still-warranted component can. We check your purchase date and warranty status before ordering parts, and we tell you exactly what is OEM versus aftermarket before you decide. Call (877) 565-7563 and we can walk through your specific warranty situation.
OEM DuraFlex caps and collars typically arrive in three to five business days from regional distribution. We stock Gelco and Famco equivalents that match DuraFlex specifications for same-day installation if your cap is leaking now and you do not want to wait. We will explain the fit and finish difference, and you choose. For an urgent leak, call (877) 565-7563, we answer live.
Repair is cheaper if the crown has minor surface spalling and the structural base is sound, typically $340-$580. Coating with HeatShield Cerfractory Foam costs more, $420-$780, but it is the better value when the crown has deeper cracking or thin spots common on 1980s Orlando homes. We show you the camera footage and recommend based on what we see, not what costs less. Call for a free estimate.
Yes. DuraFlex, HeatShield, and Gelco components are designed to industry-standard flue dimensions, and we carry adapter collars and storm collars that mate them properly. We do not force a fit with sheet metal screws and hope. The connection is sealed, tested, and photographed. If you are unsure what liner you have, we identify it during inspection. Call (877) 565-7563 to schedule.
A properly installed 304-grade stainless DuraFlex cap lasts ten to fifteen years in Orlando before mesh fatigue becomes likely. The 316-grade mesh extends that to fifteen to twenty years. The difference is real, we have replaced DuraFlex SW caps in College Park that failed at eight years due to lake-effect humidity, and others in Winter Park that made eighteen years because they sat higher and dried faster. Crown condition and overhang depth matter as much as the cap itself. We assess both and tell you what to expect. Call for a free estimate.
