DuraFlex Chimney Inspection Nationwide

DuraFlex Chimney Inspection in Miami: What to Know First

We provide independent DuraFlex chimney inspection in Miami, Florida, with most inspections completed in under two hours and a written report in your hands before we leave the driveway. A standard DuraFlex inspection runs between $189 and $349 depending on the level of inspection and whether we’re running a camera down the flue. We’re not a DuraFlex dealer and we’re not authorized by the manufacturer, so our only interest is telling you honestly what’s going on inside that liner. If you own a home in Miami with a DuraFlex system and you haven’t had it looked at in the last twelve months, call us at (850) 787-8597 and we’ll schedule a time that works.

This page is for Miami homeowners who specifically have a DuraFlex liner or venting system and want to know what a real inspection looks like, what it costs, and what we find that other companies miss. Nathan Corliss and our crew have inspected DuraFlex systems in everything from 1920s Coral Gables bungalows to high-rise condos in Brickell, and we’ve learned a few things about how these systems age in a humid coastal climate that you won’t find in any installation manual.

How DuraFlex Products Fail – and How We Fix Them

DuraFlex makes a solid product. But Miami does things to stainless steel that most of the country doesn’t deal with, and we’ve seen the same handful of issues show up year after year. Here’s what we actually find during inspections:

• DuraFlex 316L liner pitting near the termination cap. The 316L alloy is the right call for a gas or oil flue, but in Miami’s salt air, the top three feet of the liner take a beating. We regularly see pinhole corrosion where the liner exits the chimney crown, especially on homes within two miles of Biscayne Bay. The fix is usually replacing the upper section and resealing the crown, not the whole liner. A camera inspection tells us whether the pitting goes deeper.
• Coupler separation on DuraFlex DL (double-wall) systems after a chimney fire. If the previous homeowner ever had a creosote fire, the couplers between liner sections can warp just enough to lose their seal without showing visible damage from the top. We find this on older installations where the original sweep never ran a camera. The repair is coupler replacement and a full reseal, which restores the UL listing.
• Improper pitch on horizontal DuraFlex Pro runs in zero-clearance fireplaces. DuraFlex specifies a quarter-inch rise per foot on horizontal venting. In Miami, where fireplaces are often retrofitted into existing walls, we see runs that slope the wrong way or sag in the middle. That pools condensation and acidic residue, which eats the inner wall over time. We measure pitch on every horizontal run we inspect, and we’ve corrected dozens of them.
• Tee-body blockage at the base of DuraFlex chimney liners serving oil furnaces. Oil burns dirtier than gas, and the tee at the bottom of the liner collects soot and scale faster than most homeowners expect. In Miami’s humidity, that soot cakes instead of falling away. During a Level 2 inspection, we remove the tee cap and clean it out, and we’ll show you the photo of what came out. If it’s bad enough, we recommend stepping up the sweep schedule to every six months.
• Liner insulation breakdown on DuraFlex Smooth Wall installations. The foil-backed ceramic wrap does a good job when it’s installed dry. In Miami, moisture gets behind the mesh at the chimney top and the insulation slumps, leaving cold spots where creosote condenses faster. We see this on wood-burning systems that haven’t been re-topped in a decade. The fix is insulation replacement and a proper rain cap, not liner replacement.

These are the things we look for because we’ve learned where DuraFlex systems fail in this climate. A generic chimney sweep who inspects a hundred different brands might miss the pitch issue on a horizontal run or write off the pitting as normal wear. We don’t write off anything without showing you the camera footage.

Our DuraFlex Chimney Inspection Process

When you call us for a DuraFlex inspection in Miami, here’s what happens from the first phone call to the moment we hand you the report:

1. 1
   You call, a real person answers. Twenty-four hours a day, seven days a week. No voicemail. We’ll ask what type of DuraFlex system you have, when it was last serviced, and what’s making you want the inspection now.
2. 2
   Nathan or one of our techs arrives in the scheduled window. Background-checked, uniformed, and carrying the written price we quoted on the phone. You sign off on it before we touch a ladder. If we find something that changes the scope, we stop and talk to you first.
3. 3
   We run the appropriate level of inspection. A Level 1 is visual, from the firebox to the cap. A Level 2 adds a camera run through the entire DuraFlex liner, which is what we recommend for most Miami homes because salt-air pitting doesn’t show up from the top. A Level 3 is when we have to remove a section of the liner or chase to see what’s behind it.
4. 4
   We make a parts decision with you, not for you. If the liner needs repair, we’ll tell you whether an OEM DuraFlex part is the right call or whether a quality equivalent does the job at a lower price. DuraFlex’s warranty only covers manufacturing defects in the liner itself, and using aftermarket couplers or caps doesn’t void your coverage as long as the liner itself isn’t modified. We’ll walk you through that before you spend a dollar on parts.
5. 5
   We test, document, and leave it cleaner than we found it. Every inspection includes photos or video of what we saw, a written report, and a written guarantee on any repair we perform. The Kingswell Guarantee covers our work for a full year. If a repair fails inside that window, we come back and fix it at no charge.

That’s the Kingswell Way: say the price, show up in the window, leave it cleaner, put the guarantee in writing, come back if it fails. Nathan’s been doing it that way since he first started working chimneys, and he’s not about to change now.

What DuraFlex Chimney Inspection Costs in Miami

Here’s the honest price posture, because nobody should have to guess what a chimney inspection costs before the truck shows up:

• Level 1 inspection (visual, no camera): $189 to $249. Good for newer homes with no known issues and a recent service history.
• Level 2 inspection (camera through the full DuraFlex liner): $289 to $349. This is what we recommend for most Miami homes, especially if you’ve never had a camera inspection or you’re within a few miles of salt water.
• Level 3 inspection (liner section removal or chase access): $500 to $900, quoted in writing before we start. This is rare, but when a liner has failed internally, the only way to see it is to open it up.

What moves the price: chimney height, roof pitch, access difficulty (we see a lot of steep tile roofs in Coconut Grove and Coral Gables), and whether we’re removing a cap or tee for access. We give you the exact number in writing before any work starts, and the number on the invoice is the number we quoted at the door. If you want a ballpark over the phone before scheduling, call (850) 787-8597 and we’ll be straight with you.

Why Miami Homeowners Call Ashby Chimney Miami for DuraFlex Work

Most of the people who call us have been burned before. A technician who never showed. A price that doubled once the ladder came off the truck. A liner repair that cracked again six weeks later and the company wouldn’t answer the phone. We built Ashby Chimney Miami to be the opposite of that, and we put it in writing.

We’ve been doing this since 2002, and this location operates under the Kingswell Guarantee: a written price before any work starts, a written guarantee on every repair, and a free second visit if the repair fails inside the guarantee period. That’s the 365-Day Done Right Promise, and it applies to every DuraFlex inspection and repair we do. We also work with HeatShield and Gelco systems, so if your venting isn’t DuraFlex, we’re not going to turn you away or pretend we can’t handle it. We work with the materials the job needs, not whatever’s in the van.

Tell me the price first, then explain the work – everything else is just noise. That’s the standard Nathan Corliss holds for every job, and it’s why Miami homeowners who’ve been let down tend to stay with us after the first call.
