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 Cleaning in Marietta, GA | Emberly Chimney Cleaners Marietta
Chimney Sweep in Marietta for DuraFlex systems typically runs $225-$395 for a full Level 2 inspection, sweep, and camera documentation of the stainless liner system. We’re an independent DuraFlex service shop, not manufacturer-authorized, which means we source genuine OEM couplers and insulation blankets through our Haven buying network while quoting every job in writing before any brush touches your flue. Call (470) 288-2763 for a free estimate - estimates include the camera scan, not a flashlight peek.
Our crew has swept, relined, and repaired DuraFlex stainless chimney systems across Cobb County since the 1970s subdivision boom made them standard. We know DuraFlex’s twist-lock joint system, inner/outer wall construction, and insulation blanket requirements cold. DuraFlex sales & service is what we do, and Marietta’s mix of aging prefab chases and historic masonry stacks is the territory we cover.
Why Marietta Residents Choose Us for DuraFlex Service
Corrine Halstead grew up in Queens, picked up her first brush at Apex Technical School in Manhattan, and has spent the better part of two decades cleaning and inspecting chimneys across Marietta. She’s worked plenty of afternoons on older homes along Whitlock Avenue where the masonry tells its own story. That background shows up in how we run every job: camera first, quote second, work third - in that order, every time.
We are not a dispatch mill. When you book DuraFlex service with us, you get a named technician, a text when they’re en route, and a documented photo record before anyone packs up. Clause 4 of the Haven Standard requires that photo record on every job - we’ve done it that way since 2009, back when most companies were still calling a flashlight look an “inspection.” Our materials come through the Haven buying network from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, which keeps customer prices honest without cutting corners on OEM compatibility.
Marietta homeowners research before they call. They read the three-star reviews. They want the price on the page and the camera footage in their inbox. We built our process for exactly that customer.
Common DuraFlex Chimney Cleaning Problems We Solve in Marietta
- Compression or crush damage at the top plate. A prior installer over-tightened the top plate or forced the DuraFlex liner through an offset in the chase. Draft drops. The cap won’t seat clean. We see this often in East Cobb’s 1980s-90s prefab builds where the chase was framed tight to save siding costs. We cut back the damaged section, re-terminate with a proper DuraFlex top plate, and show you the before-and-after on camera.
- Inner-wall pitting from acidic condensate. Marietta’s January lows hover around 34°F - cold enough to want a fire, mild enough that most DuraFlex-lined fireplaces burn only occasionally. Those low-temperature, incomplete burns deposit sticky second-stage creosote that sits on the 316L stainless inner wall. The acidity pits the metal from the inside out. In colder markets, that creosote would burn off during a hot winter fire. Here, it just accumulates.
- Failed or missing insulation blanket. DuraFlex Insulated Flex relies on its blanket to keep flue gases warm and moving. When the blanket degrades or was never installed correctly in an exterior chase, heavy condensation forms on the liner surface. Creosote adheres in sheets. The surrounding refractory cracks hide underneath. We pull the liner, assess the blanket, and replace with genuine DuraFlex insulation where the liner itself is still serviceable.
- Disconnected twist-lock joints after decades of thermal cycling. The DuraFlex Relining System and DuraFlex Pro kits use twist-lock couplers between sections. In zero-clearance fireboxes that have been heated and cooled a few hundred times across thirty years, those joints can jump apart. Flue gas and creosote escape into the chase instead of rising up the liner. We were called out to a 1992 East Cobb subdivision home off a Lower Roswell Road cul-de-sac where the homeowner had never had the fireplace cleaned in the twelve years she’d owned it. Our tech pulled the damper and put a camera up the DuraFlex flexible liner and found the twist-lock joint about four feet up had jumped apart, with glazed second-stage creosote bridging the gap and a cracked refractory panel in the Heatilator box below. We swept and de-glazed the liner, re-seated and re-clamped the DuraFlex joint, and recommended the refractory panel be replaced before the next burn season.
- Glazed creosote bonded to the stainless inner wall. This is the Marietta special. Our DuraFlex sweeps here routinely find glazed creosote that crews in colder markets never see - dry, flaky soot is what you get when fireplaces burn hot and often. Here, the sticky stuff polymerizes onto the 316L wall and requires mechanical de-glazing, not just a brush pass. We use rotary chains and whips designed for stainless liners, then verify the surface is clean with the camera before we quote any follow-up work.
BeforeAfterDuraFlex Service in Marietta: What Local Conditions Mean for Your Equipment
Marietta’s mild winters mean most DuraFlex-lined fireplaces in East Cobb and West Cobb get burned only a handful of times a year, which produces sticky second-stage creosote that never gets hot enough to burn off - so our DuraFlex sweeps here routinely find glazed creosote bonded to the stainless inner wall instead of the dry, flaky soot crews see in colder markets. That same intermittent use pattern masks other problems. A homeowner who burns four times a winter won’t notice a slowly degrading draft or a hairline crack in the refractory panel. The fireplace sits idle from March through November, and the first fire of the season is often the test that reveals a jumped joint or a blocked cap.
The metro Atlanta area averages roughly 50 inches of rain annually. Marietta’s clay-heavy soil shifts with wet-dry cycles, stressing chimney foundations and accelerating mortar joint deterioration in older masonry stacks. For DuraFlex relines in historic neighborhoods around Marietta Square - where some chimneys predate the Civil War with soft lime-mortar joints - that soil movement can offset the chase and strain the flexible liner at its connection points. We document those offsets with the camera before quoting any adjustment. Marietta service area coverage means we understand which neighborhoods have which problems, because we’ve been on those roofs.
DuraFlex Models & Products We Service in Marietta
We work on the full DuraFlex product line: the DuraFlex Relining System in 316L stainless for wood-burning applications and AL 29-4C for high-efficiency gas setups; DuraFlex Pro flexible stainless liner kits; DuraFlex Insulated Flex pre-insulated liner for exterior chases; and DuraFlex rigid stainless pipe sections used in prefab relines. Our Marietta warehouse stocks genuine DuraFlex OEM couplers, top plates, caps, and replacement insulation blankets for same-week turnaround on our Chimney Repair in Marietta.
We use genuine DuraFlex OEM couplers, top plates, caps, and insulation blankets wherever the liner is still serviceable, because those fittings are what keep the twist-lock system sealed and code-compliant. When a DuraFlex liner is pitted through the inner wall or crushed at multiple joints, we recommend replacement rather than patching - a compromised stainless liner is a safety issue, not a cosmetic one - and we’ll show you the camera footage before quoting either path.

FAQs - DuraFlex Chimney Cleaning in Marietta
A Level 2 inspection is what your DuraFlex system needs if it has been more than a year since the last professional service, if you’re buying or selling the home, or if you’ve changed anything about the appliance or fuel type. Level 2 means a camera scan down the full flue length, which is the only way to verify twist-lock joint integrity and inner-wall condition on a flexible stainless liner. We include this as standard on every DuraFlex visit - not an upgrade. Call (470) 288-2763 to schedule; we’ll confirm whether your situation calls for Level 2 documentation.
Yes, and we do it regularly in Marietta. Glazed creosote requires rotary mechanical de-glazing with chains and whips designed for 316L stainless - wire brushes will scar the inner wall and create new pitting sites. We de-glaze, then camera-verify the surface is clean before we close the job. If the creosote has bonded so heavily that the liner wall is pitted underneath, we’ll show you that footage and quote replacement rather than cosmetic cleaning. Call (470) 288-2763 for a free inspection and honest assessment.
Not necessarily. Cracked refractory panels in a Heatilator, Superior, or similar prefab box are a code-level fire hazard, but they’re replaceable components. We evaluate whether the DuraFlex liner itself is still sound - twist-lock joints sealed, inner wall intact, insulation in place. If the liner passes camera inspection, we replace the panels and you’re back in service. If the liner is also compromised, we’ll quote both and let you decide. Either way, you get camera evidence before any work is authorized. Call (470) 288-2763 to book the inspection.
Marietta’s humidity and 50-inch annual rainfall pull moisture down the flue, reactivating creosote deposits that dried out during burning season. A properly capped DuraFlex system with intact top plate and sealed joints minimizes this, but if your cap is damaged or the chase leaks, summer air pressure differentials draw that odor into the living space. A Level 2 inspection identifies whether the smell is a cap issue, a liner leak, or simply heavy buildup needing removal. Call (470) 288-2763 and we’ll trace the source with the camera.
Yes, if the DuraFlex liner is sized correctly for the insert’s BTU output and venting requirements. We measure the liner diameter, inspect for pitting or joint separation, and verify the chase can handle the insert’s exhaust profile. Many East Cobb homes from the 1980s-90s have DuraFlex Relining Systems that were installed for open fireplaces and need a liner downsize or direct-connect adapter for a modern EPA-certified insert. We source insert-compatible components through our Haven buying network and quote the full scope in writing before ordering parts. Call (470) 288-2763 to discuss your setup.
