Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterDuraFlex Chimney Liner & Rebuild in Marietta: What to Know First
We provide independent DuraFlex chimney liner & rebuild in Marietta, typically completing liner replacements in one to two days and partial rebuilds within a week. Every job starts with a camera-scan inspection and a written price before any work begins - no exceptions. If you own a DuraFlex-lined chimney in East Cobb, Whitlock Avenue, or anywhere in Marietta and you’re seeing rust flakes in the firebox, draft problems, or a failed inspection report, this page explains exactly what we find and what it costs. Call (470) 288-2763 for a free estimate.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW (stainless wrap) liner separation at the collar weld. We see this most in Marietta homes built between 1995 and 2010 where the original installer used an oversize collar on a standard flue. The weld fatigues from thermal cycling, especially after those 20-degree January nights followed by 60-degree afternoons that are common here. We cut back to sound metal, source a matching DuraFlex collar through our Haven buying network, and reweld with back-purged TIG - not the MIG patches some shops try.
- DuraFlex Pro liner corrosion at the water-heater connection. This series uses a lighter-gauge alloy at the tee. When a gas water heater vents into the same flue as a fireplace, the condensate is acidic and concentrates at the tee. We replace the tee with a heavier aftermarket equivalent from Olympia Chimney - same OD, better wall thickness - and reroute condensate where possible.
- DuraFlex AL (aluminum) liner sag in tall Marietta chimneys. The AL series was sold as a cost-saving option for gas-only applications, but in two-story Colonials off Roswell Road the 30-foot unsupported run can belly over time. We find the sag with a camera, then either install a DuraFlex-supported replacement or switch to a stainless flexible liner if the appliance mix has changed.
- DuraFlex rigid-to-flexible transition joint failure. The factory transition sleeve relies on a compression fit that loosens after repeated heat cycles. In older Marietta brick chimneys with offset flues, the flex section takes lateral load and the joint works itself open. We pull the assembly, inspect the rigid section for cracks, and reinstall with a mechanically locked transition - not just more sealant.
- DuraFlex liner de-lamination after Class III creosote fire. Class III creosote is the glazed, tarry buildup that burns above 2000°F. Even stainless liners can spall internally. We camera the full length to map the damage, then quote either a sectional DuraFlex replacement or a full HeatShield Cerfractory foam reline if the terracotta is still sound underneath.
Our DuraFlex Chimney Liner & Rebuild Process
- 1
Camera inspection first. Corrine Halstead runs a chimney camera the full flue length before quoting any DuraFlex work. We document liner condition, joint locations, and any offset or damage. Clause 4 of the Haven Standard requires this photo record on every job - we’ve done it since 2009.
- 2
Written price and scope. You get a single-page written quote with line items: parts, labor, disposal, and warranty terms. No verbal estimates. No “we’ll see when we get into it.”
- 3
Parts decision: OEM DuraFlex or quality equivalent. We source DuraFlex direct when the series is current and the warranty matters. For discontinued lines or when a heavier specification makes sense, we pull from Olympia Chimney or Gelco through our Haven buying network - always with written justification.
- 4
Installation or rebuild. Liner jobs get pulled from the top, inspected on the ground, and replaced with proper insulation pack where required by code. Rebuilds follow NFPA 211 clearances and get a mid-point camera check before close-up.
- 5
Smoke test and final documentation. We pressure-test or smoke-test every DuraFlex liner we install, then deliver your photo record, written warranty, and 365-Day Done Right Promise card before we leave.
BeforeAfterWhat DuraFlex Chimney Liner & Rebuild Costs in Marietta
| Service | Typical Range | What Moves the Price |
|---|---|---|
| DuraFlex liner section replacement (single point) | $1,400 - $2,200 | Height of chimney, access difficulty, collar availability |
| Full DuraFlex flexible liner replacement | $2,800 - $4,500 | Flue diameter, insulation requirement, appliance connections |
| DuraFlex liner + partial chimney rebuild | $4,500 - $7,800 | Courses of brick to replace, crown condition, scaffolding needs |
| Full chimney rebuild with new liner system | $8,500 - $14,000 | Height, brick matching, cap/crown/cricket work |
These are real ranges for Marietta homes we’ve worked - not teaser rates. A two-story colonial off Paper Mill Road with a straight flue sits at the lower end. A three-story custom build with an offset flue and a deteriorated smoke chamber sits higher. We bring a written price to every estimate call, and our Free Second Opinion applies to any competitor’s written quote you bring us. Call (470) 288-2763 for an exact figure - estimates are free.

We’ve inspected over 38,000 chimneys since 2009, and a meaningful share of those have been DuraFlex installations in Marietta and Cobb County.

Our technicians are background-checked, uniformed, and assigned by name; you get a text when they’re on the way. If DuraFlex parts are back-ordered, we have HeatShield and Gelco equivalents in our Haven network to keep your job moving. Every repair carries the 365-Day Done Right Promise: if it’s not done right, we make it right. Camera first, quote second, work third - in that order, every time.
FAQs
No, if the repair uses DuraFlex OEM parts and follows their installation guidelines. As an independent DuraFlex service provider, we are not affiliated with or authorized by DuraFlex, but we source their factory parts when warranty preservation matters and document the installation for your records. If the warranty has already expired or the series is discontinued, we may recommend a quality equivalent from Olympia Chimney or Gelco with written justification. Call (470) 288-2763 to discuss your specific liner.
The camera tells the story. A single point failure - a separated collar, a cracked tee - usually means sectional repair. Multiple corrosion spots, internal spalling, or a belly in a long unsupported run means full replacement is the honest recommendation. We show you the footage and explain which category you’re in before quoting either path. Estimates are free - call (470) 288-2763 to schedule.
Most DuraFlex liner replacements in Marietta are completed in one to two days. A straightforward pull-and-replace on a single-flue chimney with good roof access is often a single day. Jobs requiring scaffolding, multiple appliance reconnections, or coordination with a partial rebuild may stretch to two or three days. We give you a written timeline with your written price.
Sometimes. DuraFlex AL and early SW series parts are increasingly scarce. When factory parts are unavailable, we source dimensionally matched equivalents through our Haven buying network - typically Olympia Chimney or Gelco - and note the substitution in your written scope. We never install a part we can’t stand behind.
A compromised liner allows exhaust gases, including carbon monoxide, to leak into wall cavities or living space. In Marietta’s heating season, that’s a real hazard. Separated joints also admit creosote and moisture that accelerate masonry damage. We don’t scare-sell: if the camera shows a problem that can wait six months, we’ll say so in writing. If it needs immediate attention, we’ll show you why. Call (470) 288-2763 for a camera inspection and honest timeline.
