This page is for Marietta homeowners who already have a DuraFlex flue liner, or who bought a house where the seller said the liner was “recently replaced.” We’re an independent DuraFlex service provider, not a factory warranty shop. That matters because we’ll tell you what we actually see in the flue, not what a sales sheet says you should buy.

Key takeaways:

• DuraFlex liners fail in specific, predictable ways that a generic inspection often misses.
• Camera inspection is standard on every DuraFlex job we do in Marietta, not an upsell.
• We quote a flat price before work starts and put the guarantee in writing.

How DuraFlex Products Fail – and How We Fix Them

DuraFlex makes a solid liner system, but like every stainless product, it has failure points. Here’s what we actually find in Marietta chimneys, which series shows up most, and what we do about it.

• DuraFlex 316L corrugated liner seam separation near the smoke shelf. This is the most common issue we see in Marietta’s older two-story Colonials. The corrugated profile gives the liner flexibility, but the seam weld takes stress every time the flue heats and cools. After enough cycles, the seam can open a hairline gap. A camera inspection catches it as a thin dark line on video; a visual-only Level 1 misses it entirely. Fix: a targeted seam repair with high-temp alloy, and if the liner’s over fifteen years old, we’ll have an honest conversation about whether patching makes sense.
• DuraFlex 304 alloy pitting from condensation in short, exterior-chimney runs. Marietta’s humidity and our cool winter nights create more flue condensation than a dry-climate chimney sees. On exterior chimneys, especially where a liner was sized a touch wide for the appliance, we find pitting about a third of the way up where exhaust gas cools and sits. The fix isn’t another liner in the same size; it’s often re-evaluating the diameter against the appliance’s BTU output, then quoting a correctly sized replacement if the pitting has gone deep.
• Improper DuraFlex installation: uninsulated liner in a zero-clearance chase. DuraFlex sells an insulation wrap system for a reason. When we see an uninsulated liner in a Marietta chase, we know whoever installed it skipped a step because it was faster. That liner runs too hot on the chase walls and too cool at the top, and you get a mess of creosote plus a draft that fights you. The fix is pulling the liner, insulating it properly, and sometimes running a fresh section if the old one has warped.
• DuraFlex teardrop connector loosening at the appliance outlet. The connector that mates the liner to your stove or insert does the hard work of containing hot gases at the tightest point. On a lot of DuraFlex jobs, we find this connector has loosened from years of brick expansion and contraction. It’s a two-minute fix with the right clamp kit, but if it’s left, exhaust leaks into the chase and you lose draft. We check this on every inspection because it’s the cheapest fix that prevents a serious problem.
• DuraFlex’s own listed clearance requirements ignored by the original installer. DuraFlex documentation gives specific clearance-to-combustibles numbers, and we’ve seen plenty of Marietta installs where framing sits closer than the spec. Nothing has caught fire, which the homeowner assumes means everything’s fine. The real risk is hidden charring inside the chase that a visual inspection can’t see. We flag any clearance concern on the inspection report and recommend repair only when we can show you a picture of why we’re concerned.

Our DuraFlex Chimney Inspection Process

Here’s how a DuraFlex inspection runs start to finish when you call Ashby Chimney Marietta.

1. 1
   You call (478) 796-8742. A live person answers, takes your info, and asks what appliance the liner serves. No voicemail maze, no “we’ll call you back within two business days.”
2. 2
   We arrive in the window we gave you. Our techs are background-checked and uniformed, so you know who’s walking through your door. We introduce ourselves, walk the fireplace or stove, and confirm what we’re inspecting before any work starts.
3. 3
   Written price at the door. You’ll see the number before we touch anything. The invoice number matches the quote number. That’s the Kingswell Way: say the price first.
4. 4
   Camera inspection of the full liner run. We feed a video camera from the appliance outlet up through the DuraFlex liner to the cap. You’re welcome to watch the screen with us. You’ll see exactly what we see. We also check the connectors, the cap, the chase clearances, and the mortar joints at the crown.
5. 5
   Photo report and flat-price repair quote. If we find something we can fix, we quote a flat number. If your liner needs replacement, we’ll tell you why, show you the footage, and recommend the right fix with DuraFlex parts or a quality alternative depending on what’s actually needed.
6. 6
   Everything in writing. Your repair quote, your guarantee, and your inspection findings all land on paper before we leave. If we repair and it fails inside the guarantee period, we return at no charge. That’s the 365-Day Done Right Promise.

What DuraFlex Chimney Inspection Costs in Marietta

No mystery pricing here. A Level 1 visual inspection with a basic flue check runs about $189. A full Level 2 camera inspection, which is what we recommend for any DuraFlex liner that hasn’t been looked at in three years or more, runs $249 to $349 depending on the home’s height and access. If we’re inspecting a home you’re buying or selling in Marietta, expect the same camera scope and photo report.

If the inspection finds a repair, the quote is separate and in writing before we do anything. Simple fixes like a connector clamp or cap replacement usually add $80 to $250. Liner replacement lands in the $2,800 to $6,500 range depending on length, diameter, insulation needs, and access. The price moves based on liner height, whether the old liner needs to be broken out, and whether the chase needs insulation work. Call (478) 796-8742 for an exact quote. Estimates are free.
