AfterHow Much Does Chimney Repair Cost in Marietta?
Chimney repair in Marietta, GA typically costs between $250 and $1,800 depending on what’s wrong. Most homeowners in Cobb County pay around $450 to $900 for common fixes like crown repair, flashing replacement, or minor masonry work. The big-ticket item is a flue liner replacement, which runs $3,500 to $7,000 when it’s required, but many repairs fall well under $1,000.
If you’ve been putting off a chimney inspection because you’re worried about the number, we get it. At Ashby Chimney Marietta, we give you a written price before any work starts, so you’ll never get a surprise invoice at the end. Call (478) 796-8742 and we’ll talk through what you’re seeing with your chimney, then schedule a time that works for you.
Chimney Repair Cost Breakdown (2026)
Here’s what we’re seeing across Marietta and the surrounding Cobb County neighborhoods in 2026. These aren’t national averages from some website that’s never stepped foot in Georgia. These are the numbers we work with every week from East Cobb to Powder Springs.
| Repair Type | Typical Cost in Marietta | What It Involves |
|---|---|---|
| Minor brick repair (spalling) | $250 – $600 | Replacing 5-15 damaged bricks, repointing mortar joints |
| Chimney crown repair | $400 – $900 | Sealing cracks or rebuilding the concrete cap at the top |
| Flashing repair | $350 – $750 | Resealing or replacing the metal where the chimney meets the roof |
| Chimney cap replacement | $200 – $500 | New cap to keep rain, animals, and debris out |
| Firebox repair | $600 – $1,800 | Rebuilding the firebrick lining where you build your fire |
| Damper replacement | $300 – $700 | New damper plate or top-sealing damper |
| Flue liner repair (stainless steel) | $3,500 – $7,000 | Installing a DuraFlex liner inside the existing chimney |
| Full chimney rebuild (above roofline) | $4,000 – $12,000 | Tear down and rebuild when masonry is beyond saving |
What drives cost up or down? Ladder access is a big one here in Marietta. Homes in older neighborhoods like Whitlock Avenue or the historic district tend to have steeper roof pitches and taller chimneys, which means more time on the ladder and more setup. Two-story chimneys with difficult roof access will always cost more than a single-story ranch in East Cobb where we can set up in the driveway. The condition of your existing masonry matters too. If the bricks are so soft they crumble when we touch them, we’re looking at a bigger job than a simple crown seal.
One thing that keeps costs predictable is knowing what you’re dealing with before we start. That’s why we show up, do a level of inspection that matches what you’re calling about, and write the number down. No vague “we’ll see once we get in there” pricing. The price on the quote is the price on the invoice. That’s the Kingswell Way, and we’ve been doing it that way since 2002.
What Affects Chimney Repair Pricing in Marietta
- Height and roof access. A chimney on a two-story Colonial with a 12/12 pitch roof requires different equipment and more time than a single-story ranch. We price for the actual conditions at your house, not a generic average.
- Moisture damage from Georgia weather. Marietta gets about 52 inches of rain a year, plus freeze-thaw cycles in January and February that crack bricks and crowns. Water intrusion is the root cause of most chimney problems we see in this market.
- Age of the chimney. Homes built in the 1960s through the 1980s around Sprayberry and Piedmont Bend often have original clay flue liners that have cracked from decades of heating and cooling. Once that liner goes, repairs broaden out beyond a simple patch job.
- Type of repair materials. We use professional-grade materials from brands like DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. These cost more than whatever is on the shelf at a big-box store, and they last longer too. You’ll see the brand names on your quote.
- Extent of hidden damage. Sometimes what looks like a small crack on the outside is a sign of bigger issues inside the flue. An inspection gives us the full picture before we quote, so you’re not paying for a patch that fails in six weeks.
- Time of year. Like most trades in Georgia, chimney work slows down in summer and picks up hard in October and November. Pricing stays consistent, but scheduling flexibility is easier if you call before the fall rush.
How to Save on Chimney Repair
The honest answer is that chimney repair isn’t a place to shop for the lowest bid. A $200 “fix” that doesn’t address the moisture problem means you’ll pay $1,200 next year when the damage spreads. That said, there are legitimate ways to keep costs down.
First, get your chimney inspected before problems become visible. Water damage inside a chimney doesn’t announce itself. By the time you see staining on the drywall around the fireplace or smell something musty, the repair has already grown. Annual inspections cost far less than major repairs, and they catch crown cracks and flashing failures early.
Second, bundle the work. If you need a crown repair and a new cap, doing them together saves you a second trip charge and ladder setup. We’ll show you the combined price in writing so you can see the difference.
Third, ask about the guarantee before you sign anything. A repair with no guarantee is a gamble you don’t want to take. Every job we do carries a written guarantee. If it fails inside the guarantee period, we come back and fix it at no charge. It’s called the 365-Day Done Right Promise, and it’s not an add-on. It’s how we’ve operated since 2002.
And yes, estimates are free. Call us at (478) 796-8742 and we’ll come out, look at your chimney, and hand you a written number. No obligation. No pressure. Just a real price from a real person standing in your living room.
Common Chimney Problems in Marietta and What They Cost to Fix
Every market has its patterns. Here’s what we see most often in Marietta specifically, and what you’re looking at to fix each one. This is also a good section for the Chimney Repair in Marietta page if you want to read more about how we approach each job.
Cracked or Spalling Bricks
When bricks on the exterior of your chimney start flaking, crumbling, or showing white staining (that’s efflorescence, the salt deposits left behind when water moves through masonry), you’ve got moisture working its way in. In Marietta’s humid climate, this happens faster than in drier parts of the country. Repointing and replacing spalled bricks typically runs $250 to $600 for a small section. Left alone, it becomes a structural problem that costs thousands. We see this a lot on chimneys along Roswell Road and other corridors where homes have been exposed to decades of weather.
Crown Failure
The crown is the concrete pad that sits on top of your chimney, shedding water away from the flue. When it cracks, water gets in and freezes during those cold snaps that roll through Cobb County in January. A cracked crown usually costs $400 to $900 to repair properly. The key word is properly. A thin layer of sealant slapped over a structural crack will fail within a season. We rebuild crowns with the right mix and proper slope so water runs off instead of pooling.
Faulty Flashing
Flashing is the metal barrier where your chimney meets the roof. In Marietta, we get enough rain and wind that flashing takes a beating. When it fails, water runs straight down the chimney and into your attic. Flashing repair runs $350 to $750 depending on how much needs replacement. If you’re seeing water stains on the ceiling near the fireplace, this is the first thing we check before you call a roofer.
Cracked Flue Liner
Here’s the one that catches people off guard. Your flue liner is the clay or steel tube that vents combustion gases up and out of your home. If it cracks, those gases can leak into your living space. This isn’t a cosmetic issue and it’s not something to put off. Stainless steel liner installation with a DuraFlex system runs $3,500 to $7,000 in this market. It’s the most expensive single repair, but it also has the longest lifespan and the highest safety return. Clay liners crack over time from thermal shock, especially in older Marietta homes that have been heated with wood for decades.
Repair vs. Replace: When to Fix and When to Rebuild
Some chimneys can be repaired. Some need to come down and go back up. Here’s how to know where you stand without paying for a guess.
If the masonry is sound and the problem is isolated, you repair. A cracked crown, a leaking flashing, a bad damper, a handful of spalled bricks. These are localized fixes. You spend a few hundred dollars, get a written guarantee, and move on with your life.
If the chimney is leaning, if the brick is soft all the way through, or if the firebox and flue have both failed, you’re looking at a rebuild or major restoration. Full chimney rebuilds above the roofline run $4,000 to $12,000 in Marietta. That’s a big number, but structural failure carries bigger numbers if the chimney collapses onto your roof or someone gets hurt.
Our approach is to show you exactly what we found, explain what has to happen and what can wait, and give you a written price for both. You decide. We don’t push rebuilds when a repair will do. Nathan Corliss, who leads our team here in Marietta, has been doing this long enough to know that straight talk is the whole job. Say the price, do the work, stand behind it.
Why Chimney Repairs Cost What They Cost
Chimney work isn’t cheap because it’s slow, physical, and dangerous. The materials aren’t the expensive part. It’s the labor, the ladder time, and the liability.
Working on a chimney means hauling mortar, brick, and tools up ladders. It means kneeling on a roof in the Georgia sun in August and working with cold hands in February. It means doing a job that looks simple but isn’t, because water finds every mistake and punishes it. That’s why we send background-checked, uniformed technicians who do this work every day. They know what a failed repair looks like before it fails. And they carry the Kingswell Guarantee behind every job, so if something goes wrong, you’re not chasing a phone number that never answers.
We also carry professional-grade materials because the difference matters. A budget crown seal doesn’t last a full Georgia winter. A DuraFlex liner does its job for decades. HeatShield resurfacing for fireboxes holds up to direct flame. Gelco crown products survive the freeze-thaw cycles that crack cheap concrete. We don’t build quotes around whatever happened to be in the van. We build them around what will still be working ten years from now.
What the Kingswell Guarantee Covers
You’ve read the phrase a few times now, so let’s define it in plain language. The Kingswell Guarantee is the standard every independently owned Kingswell chimney company, including Ashby Chimney Marietta, operates under. It means five things:
- Say the price. You get a written quote before any work starts. The invoice matches the quote. No exceptions.
- Show up in the window. We give you a real arrival window and we hit it. If we’re delayed, we call. No silent no-shows.
- Leave it cleaner. We protect your floors, clean up after ourselves, and treat your home like we’d treat our own.
- Put the guarantee in writing. Every repair gets a written guarantee on completion. Not a verbal promise. Paper.
- Come back if it fails. If the repair fails inside the guarantee period, we return and fix it at no charge. That’s the 365-Day Done Right Promise.
This is the Kingswell Way. It’s not a marketing slogan. It’s the operating standard we’ve worked under since 2002, and it’s why homeowners in Marietta who’ve been burned by no-shows and price-switching contractors end up calling us.
