We know Mableton’s chimneys. The older brick ranches along Floyd Road, the split-levels near Nickajack Elementary, the newer builds tucked into subdivisions off Veterans Memorial Highway. Each one has its own history, and that history matters when it comes to what’s inside the flue. Our Chimney Inspection team has spent years working through Cobb County’s specific mix of housing stock, and we bring that local knowledge to every job.
Why Ashby Chimney Marietta Is Mableton’s Preferred Chimney Inspection Company
Nathan Corliss leads our team, and he’s built the company on one idea that shouldn’t be unusual but is: show the homeowner what you’re seeing before you ask them to spend a dime on repairs. Every inspection we run includes camera footage you watch alongside our technician. If we find a crack, you see the crack. If the flue is clean, you see that too and we tell you it’s clean. No mystery, no pressure.
We’ve been inspecting chimneys since 2002, and the reviews from Mableton homeowners consistently mention two things: we show up in the window we promised, and the number on the invoice matches the number we quoted at the door. That happens because we put it in writing before any work begins. The Kingswell Guarantee backs every inspection and repair we do. If a covered repair fails inside the guarantee period, we return at no charge and fix it. That’s the 365-Day Done Right Promise, and it’s not a marketing line. It’s how Nathan runs Ashby.
Response time to Mableton is typically one to three business days for routine inspections. If you’re buying or selling a home and need a real estate inspection on a deadline, we prioritize those and can often get to you faster. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops, no “we’ll call you back on Monday.”

Chimney Flue Inspection in Mableton
Chimney Flue Inspection is the core of what we do in Mableton, and for good reason. The flue liner (the clay or steel tube that vents combustion gases out of your home) is the single most safety-critical part of your chimney system. In Mableton’s older homes, original clay tile liners crack as the house settles. On a 1960s brick ranch along the Silver Comet Trail corridor, those hairline fractures have had sixty years to develop. A cracked liner lets heat and gases reach the surrounding masonry and, in the worst cases, the wood framing behind it.
A flue inspection in Mableton runs $189 – $249 when it’s part of a standard Level 1 service, and $289 – $389 when we run a camera through the full length of the flue as part of a Level 2. Most Mableton homes built before 1990 should default to the camera version. We’ll tell you plainly if a visual-only check is sufficient, and we’ll show you exactly why if it isn’t.
Camera Verification Standard
Every Level 2 inspection includes a waterproof camera run through the entire flue, top to bottom. You watch the screen while we scope it. This is the difference between finding a cracked clay tile and being told a rebuild is necessary without any evidence.
Prefab and Furnace Flues
Mableton’s newer subdivisions off Veterans Memorial Highway often have prefabricated metal chimneys or flues venting a furnace or water heater. These need a different inspection approach, checking the metal seams, the termination cap, and the clearances around the unit. We inspect those just as carefully as we do masonry stacks.
Chimney Fire in Mableton
Chimney Fire prevention starts with knowing what’s actually inside your flue before the first cold snap of the season. In Mableton, that matters more than most homeowners realize. Our humid subtropical climate means fireplaces get used in bursts: a few cold weeks in January, maybe a stretch in February, then eight months of sitting. That intermittent use creates exactly the conditions for crusty, stubborn creosote buildup that a basic sweep won’t remove and that a visual-only inspection will miss.
If you’ve already experienced a chimney fire, even a small one, the inspection changes. A fire inside a clay tile flue can crack the liner, damage the mortar joints, and compromise the smoke chamber. We inspect for that specific damage before you light another fire. The cost to inspect after a chimney fire runs $289 – $389 for a full camera scoping, and it’s the only way to know whether the chimney is safe to use.
Creosote Types and What They Mean
Third-degree creosote is a hard, shiny tar glaze that forms when heat is inconsistent. It burns at much higher temperatures and can’t be brushed out with standard tools. We look for it specifically in Mableton homes that only light fires during cold snaps. If we find it, we tell you so and explain exactly what removal will take.
After-Fire Inspection Protocol
We document everything with photos and video. Before we recommend anything, you’ll see the evidence. If damage is limited to a liner section, we talk through options like HeatShield resurfacing before anyone suggests a rebuild.
Trusted Brands We Service in Mableton
When repairs are needed, we use materials from chimney-trade brands with proven track records. That includes Famco caps and dampers, Copperfield chimney products, DuraFlex stainless steel liners, and HeatShield resurfacing systems. We stock common parts for Mableton’s typical housing styles, which means faster turnaround when a masonry chimney off Powder Springs Road needs a new cap or a cracked clay liner needs sealing. We don’t show up with whatever happened to be in the van. We show up with the right material for the job, and we tell you what it is and why we’re using it.

AfterCommon Chimney Inspection Problems We See in Mableton Homes
- Cracked clay tile liners in older brick ranches: Homes build in the 1960s and 1970s along the Silver Comet Trail corridor settle over time, and that settling cracks the original terracotta liners. In neighborhoods like Anne Place and Shannon Green, this is the single most common issue we document on camera.
- Spalling mortar at the smoke chamber: Decades of heating and cooling cycles break down the mortar joints above the firebox, especially in masonry fireplaces built before modern code requirements. Small pieces flake off over time, and the damage spreads if it isn’t addressed.
- Third-degree creosote from intermittent use: Mableton’s mild winters create a feast-or-famine burning pattern. A fireplace that sits unused for 10 months then burns hot for two weeks produces tar glaze creosote that a standard sweep can’t remove. Only a camera inspection catches it before it becomes a fire hazard.
- Unlined or improperly vented furnace flues: Many older Mableton homes have furnaces or gas water heaters venting into masonry chimneys that were never designed for it. Without a proper stainless steel liner, the acidic condensate eats through mortar and brick, and the problem often hides until water stains or a smell gives it away.

FAQs About Chimney Inspection in Mableton
Because most Mableton homes built before 1990 have original clay tile liners that are now decades into settling, weathering, and thermal stress. A Level 1 visual check can’t see inside the flue, which is exactly where the cracks are. We recommend a Level 2 camera inspection as the default for any pre-1990 chimney in Mableton, and we’ll show you the footage that justifies the recommendation. Call (478) 796-8742 to schedule one, and you’ll get a written price before we arrive.
Yes, and if anything, those chimneys need inspection more than heavily used ones. Light, intermittent use in Mableton’s mild climate creates uneven creosote deposition and crusty buildup that’s harder to remove and easier to miss visually. A camera inspection tells us exactly what’s in there, whether it’s been three fires or three hundred. Estimates are free, and we answer the phone around the clock at (478) 796-8742.
Yes, every time, no exceptions. We run the camera, you watch the screen with us, and we explain what we’re seeing in plain language. If your Mableton chimney is in good shape, we’ll tell you that and show you why no work is needed. If we find a problem, you’ll see it with your own eyes before any repair quote is written. That’s how Nathan Corliss has run Ashby since 2002, and it’s why Mableton homeowners trust us not to upsell rebuilds that aren’t necessary.
Get a second opinion that includes camera proof. We’ve inspected dozens of Mableton chimneys after another company claimed a full rebuild was needed, and in many cases the actual problem was a cracked liner or spalling mortar that we repaired with HeatShield resurfacing at a fraction of the rebuild cost. We never recommend structural work without showing you the camera footage that justifies it. If you’ve been given a rebuild quote, call (478) 796-8742 and let us scope the flue before you sign anything.
We inspect them with the same camera standard as any other flue, paying close attention to the liner material, the slope of the horizontal runs, and signs of condensate damage. Older Mableton homes often vent gas appliances into unlined masonry chimneys, which causes acidic erosion over time that’s invisible from the outside. We’ll document what we find and recommend only what the footage supports, whether that’s a stainless steel DuraFlex liner or simply a cleaning and new cap. Call (478) 796-8742 to schedule, and we’ll put the price in writing before we come out.
