AfterHow Much Does Chimney Cap & Crown Cost in Marietta?
Chimney cap and crown work in Marietta, GA typically runs between $300 and $1,500 depending on whether you’re replacing just the cap, rebuilding the crown, or doing both. A standard stainless steel cap replacement alone usually costs $300 to $600 installed, while a full crown rebuild with a new cap lands closer to $900 to $1,500. Those are the numbers we quote most often for homes in Cobb County, and they include materials, labor, and the written guarantee we put on every job.
At Ashby Chimney Marietta, we’ve been doing this work since 2002, and Nathan Corliss, who leads our team, has always done it the same way: written price before any work starts, no surprises at the door. If you want to know exactly what your chimney needs and what it’ll cost, call us at (478) 796-8742 and we’ll come take a look.
Chimney Cap & Crown Cost Breakdown (2026)
The price you’ll pay in Marietta depends on what’s actually wrong up there. Here’s what we’re seeing across the market in 2026:
| Service | Typical Cost Range (Marietta, GA) |
|---|---|
| Chimney cap replacement (standard stainless steel, single flue) | $300 – $600 |
| Chimney cap replacement (multi-flue or custom sized) | $500 – $900 |
| Chimney crown repair (patch and seal small cracks) | $250 – $450 |
| Chimney crown rebuild (full removal and re-pour, single flue) | $700 – $1,000 |
| Chimney crown rebuild (multi-flue or larger chimney) | $1,000 – $1,500 |
| Cap + crown replacement (combined job, most common) | $900 – $1,400 |
| Cap + crown + minor masonry touch-up | $1,200 – $1,800 |
These ranges reflect the Marietta market specifically. We price based on what we see when we get on the roof: chimney height, flue size, crown condition, and access. A single-story ranch in the Fair Oaks area is a different job than a three-story brick home near the Marietta Square, and the price reflects that.
What Drives the Cost Up or Down
The biggest variable is crown condition. If the crown has hairline cracks, we can patch and seal it for a few hundred dollars. If it’s spalling (crumbling) or has shifted enough to let water pool, a patch won’t hold, and a rebuild is the honest answer. Cap cost varies with flue size. Standard 8×8 or 8×13 flues take stock caps. Odd sizes mean custom fabrication, which adds $100 to $250.
Roofline access matters too. Steep pitches, tall chimneys, and clay tile roofs all add time and care, which is reflected in the quote. We’ll always write the price down before we start, so you’ll never hear a different number after the fact.
What Affects Chimney Cap & Crown Pricing in Marietta
- Crown condition and material. A cracked crown that needs sealing is a quick fix. A crown that’s eroded past the flue liner needs full removal and a new pour with proper expansion joint. That’s the difference between $350 and $1,000.
- Flue size and configuration. Single-flue caps are stock items. Multi-flue chimneys, common on older Marietta homes near Whitlock Avenue and the historic district, often need custom caps or multi-flue covers, which cost more.
- Chimney height and roof pitch. Two-story chimneys on steep roofs require more setup, safety equipment, and time. Homes in East Cobb off Lower Roswell Road with tall chimneys at the ridge line cost more to service than a low-slope ranch.
- Materials. We use caps and crown materials from recognized chimney-trade brands like Olympia Chimney, Gelco, and Famco. Stainless steel caps last longer than galvanized but cost $100 to $200 more. Copper caps are a premium option that can run $800 to $2,000 depending on size, and they patina beautifully over the Cobb County seasons.
- Condition of surrounding masonry. Sometimes the crown is fine but the brick below it is spalling. We’ll tell you what we find, and if the bricks need repointing before a new cap goes on, that’s a separate line item on the written quote.
- Time of year and weather. Chimney work in Marietta slows in late fall and early winter when everyone’s thinking about fires. Spring and summer tend to have more flexibility. Our pricing doesn’t jump with the seasons, but scheduling can be tighter in October and November.
How to Save on Chimney Cap & Crown
Saving money on chimney work doesn’t mean finding the cheapest bid. It means doing the right repair at the right time, so you’re not paying for a rebuild later. Here’s what actually helps:
- Get the cap fixed before the crown fails. A damaged cap lets rain pour straight down the flue. That water sits in the smoke shelf, rusts the damper, and eventually damages the crown from underneath. A $400 cap replacement now beats a $1,400 cap-and-crown job in two years.
- Address small crown cracks early. Hairline cracks can be sealed for a few hundred dollars. Once they widen and water freezes inside them during a Marietta winter, the crown starts breaking apart. Georgia’s freeze-thaw cycle doesn’t get as cold as the Midwest, but we get enough nights below 32°F to expand water in those cracks and make things worse.
- Combine the work. If you’re already having the crown rebuilt, adding a new cap at the same time costs less than scheduling them separately. One trip up the ladder, one setup, one written price.
- Ask about the guarantee before you hire. A cheap repair with no warranty isn’t a savings. Our repair work carries the 365-Day Done Right Promise: if it fails inside the guarantee period, we come back and fix it at no charge. That’s part of the Kingswell Guarantee, and it’s written into every job we do, not sold as an add-on.
- Get a free estimate and know your number. We give written prices before any work starts. Call us at (478) 796-8742 and we’ll come out, look at the cap and crown, and give you a number you can hold us to.
Is a Chimney Cap Really Necessary?
Yes. A chimney without a cap is an open pipe into your house. Rain comes down the flue and sits in the firebox. Birds, squirrels, and raccoons find their way in, and we’ve pulled more than one squirrel nest out of an uncapped flue in Marietta. A cap also keeps embers from lifting out of the chimney and landing on your roof or in your yard. If you’ve got a wood-burning fireplace, an uncapped chimney is a spark hazard waiting for a dry Georgia summer.
And here’s what people don’t think about: water is the thing that destroys chimneys. Crown cracks let water into the brickwork. A cap missing its screen lets rain run down the flue liner. The water soaks in, freezes, thaws, and the brick starts spalling. Once the brick face starts popping off, you’re looking at masonry repair that costs more than the cap ever would have.
Signs Your Chimney Cap or Crown Needs Replacement
- Water in the firebox after rain. If you’re seeing puddles or damp ash in the firebox after a Marietta storm, water is coming down the flue, and the cap is either missing, damaged, or the wrong size.
- Cracked or crumbling crown. Look at the cement slab around the top of the chimney. If it’s cracking, flaking, or you can see the flue liner exposed, the crown has failed.
- Animal noises from the chimney. Chirping, scratching, or fluttering usually means something has moved in through an uncapped flue.
- Rust on the damper or firebox. Rust means water has been sitting in there. Water plus metal equals corrosion, and a rusty damper is a sign the cap isn’t doing its job.
- Strong drafts or unusual smells. A missing cap changes the draft and can let debris and odor into the house.
- Visible cap damage from the ground. If the cap is bent, missing pieces, or leaning, it’s time for a replacement. You shouldn’t have to climb up to see it. A bent cap from a falling branch or a bad storm is something we see often enough after Cobb County’s spring weather.
If any of that sounds like your chimney, call us. Nathan Corliss and the team at Ashby Chimney Marietta will come out, take a look, and tell you plainly what needs fixing and what can wait. We won’t sell you a rebuild if a sealed crack is all you need.
Local Marietta Chimney Conditions That Affect Your Cap and Crown
Marietta gets about 52 inches of rain a year, which is more than the national average. That rain lands on your chimney cap and crown every time a storm rolls through. Red clay dirt from the Georgia foothills clings to everything, including chimney surfaces, and holds moisture against the masonry. Spring and summer thunderstorms can be intense, and the July sun bakes the crown dry in between. That wet-dry cycle stresses the cement and accelerates cracking.
We also work on a lot of older chimneys in Marietta’s historic neighborhoods. Homes built in the 1920s and 30s around the Marietta Square and along Cherokee Street often have chimneys built to different dimensions than modern code. That means the flue sizes aren’t standard, the crowns weren’t poured with expansion joints, and the caps may have been retrofitted decades ago. We measure everything up top so the new cap fits the way it’s supposed to.
Our Chimney Cap & Crown Process in Marietta
We follow what we call The Kingswell Way, and it’s built on five promises: say the price, show up in the window, leave it cleaner, put the guarantee in writing, and come back if it fails. Here’s how that plays out on a cap and crown job:
- Inspect and measure. We get on the roof, inspect the crown, measure the flue, check the cap, and take photos so you can see what we see. Nathan or one of our technicians will walk you through the findings before any money changes hands.
- Written price. We give you a written quote with the full scope and the exact number. That number doesn’t move unless you change the scope. No surprises at the door, no “we found more than we expected, so now it’s double.”
- Do the work. We use caps and crown materials from brands we trust: Olympia Chimney caps, Gelco crown sealants, Famco products, and DuraFlex components where applicable. These are professional-grade materials, not whatever happened to be in the van.
- Clean up. We leave the roof, the yard, and the hearth cleaner than we found them. Ashby carries ash right in the name, but we don’t leave any behind.
- Written guarantee. Every cap and crown repair gets our 365-Day Done Right Promise in writing. If the repair fails inside the guarantee period, we come back at no charge. That’s the Kingswell Guarantee, and it’s not optional.

FAQs – Chimney Cap & Crown Cost in Marietta
How much does it cost to replace a chimney cap in Marietta?
A standard stainless steel chimney cap replacement in Marietta runs $300 to $600 for a single flue, installed. If you’ve got a multi-flue chimney or need a custom size, expect $500 to $900. Copper caps cost more, starting around $800 and going up from there. Call (478) 796-8742 for a free estimate on your specific chimney.
How much does a chimney crown rebuild cost in Marietta?
A full chimney crown rebuild in Marietta typically costs $700 to $1,000 for a single flue, and $1,000 to $1,500 for a multi-flue or larger chimney. If the crown only has small cracks, sealing can cost as little as $250 to $450. We’ll tell you which one you actually need, not which one makes us more money.
Is a chimney cap and crown replacement worth it?
Yes. Combined cap and crown replacement runs $900 to $1,400 in Marietta, and it protects your chimney from water damage that can cost $3,000 to $10,000 to repair if the masonry starts spalling. Water is the single biggest threat to your chimney, and the cap and crown are what keep it out.
How long does a chimney crown last?
A properly poured concrete crown with an expansion joint should last 20 to 30 years in Marietta’s climate. A crown that was poured without an expansion joint, or one that’s been patched repeatedly, may only last 5 to 10 years. If your crown is older than two decades and showing cracks, a rebuild is likely the better long-term call.
Can you replace a chimney cap the same day?
Usually, yes. If the flue is a standard size and we have the right cap on the truck, we can replace a cap the same visit for $300 to $600. Custom sizes and multi-flue caps may need ordering, which typically takes 3 to 7 business days. Call us at (478) 796-8742 and we’ll let you know what’s in stock and how soon we can get out.
What’s the difference between a chimney cap and a chimney crown?
The crown is the cement slab at the top of the chimney that seals around the flue and sheds water off the brick. The cap is the metal cover that sits over the flue opening to keep rain, animals, and debris out. You can think of the crown as the roof of the chimney and the cap as the door over the flue. Both fail eventually, and in Marietta’s wet climate, they fail together more often than not.
