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.

Hank Delano, who leads our repair operations, holds every job to one rule: if it’s not done right, we return at no charge. That’s our 365-Day Done Right Promise, and it’s written into every repair we do in Marietta.

That disappears the moment you see your photo report from our camera inspection.
Homeowners across Marietta, from the ranch houses off Roswell Road to the newer builds near West Cobb, get the same treatment: a live person answers the phone 24/7, and a written price arrives before any tool comes off the truck.
Chimney Cap Replacement in Marietta
Chimney cap replacement is one of the most common repair calls we handle in Marietta, particularly for mid-century brick ranches where original caps have rusted through or disappeared entirely. A broken or missing cap lets rain pour directly down the flue, and that water is exactly what rots dampers, deteriorates clay flue tiles, and invites squirrels and birds into the stack. In Marietta’s older neighborhoods, we routinely pull rusted galvanized caps off chimneys that haven’t been capped properly in decades.
What the Job Involves
We remove the old cap, inspect the flue crown for cracks or spalling, and install a new cap sized to the flue tile. Most Marietta cap replacements use copper or stainless steel. Copperfield caps hold up especially well against Metro Atlanta’s humidity and frequent rain cycles. A standard cap replacement here runs $250 – $550 depending on flue size and material.
How Do You Know You Need One
Rain streaking down the brick, a damp smell near the firebox, or acorns and nesting material in the firebox are the usual tells. If your cap is cracked, rusted through, or missing entirely, replace it before wet season. Water damage from an uncovered flue is a slow, expensive repair that starts cheap if caught early.
Chimney Liner Installation in Marietta
Chimney liner installation in Marietta homes is often the repair that follows a Level 2 camera inspection, because so many original clay liners in this area have hairline cracks that cannot be seen from the roof or the firebox. The liner is the inner channel that carries smoke and carbon monoxide safely out of the house. When a clay tile cracks, the gap lets gas seep into the attic or wall cavities instead of up the stack. In Marietta’s post-war construction, original clay tile liners are now 50 to 70 years old and showing their age.
Two Approaches We Use
For smaller cracks, HeatShield resurfacing repairs the liner without removing the old one. For a liner that’s too far gone or a chimney with no liner at all, we install a DuraFlex stainless steel liner sized to the appliance. A full DuraFlex liner installation in Marietta typically runs $2,800 – $4,500, and a HeatShield repair usually lands between $900 and $2,200. Every liner job includes a final camera pass so you see the result yourself.
The Marietta-Specific Concern
Georgia’s clay soil moves, and Marietta homes sit on some of the heaviest clay in Cobb County. That movement transfers into the masonry stack and cracks clay tiles over time. A homeowner may go years without knowing, because the fireplace still draws and the chimney looks fine from the outside. The only way to know is a camera inspection, and that’s why we never recommend a liner decision without one.
Trusted Brands We Service in Marietta
We stock and install materials from brands a Marietta homeowner can research independently: Olympia Chimney, Famco, and Copperfield. If your cap was originally a Copperfield, we replace it with another Copperfield, not a generic substitute. If your liner needs resurfacing, we use HeatShield applied by trained techs, not a resin kit from a hardware store. For flue relining, we specify DuraFlex. Having parts sourced through our Atlanta dispatch means faster turnaround for Marietta jobs, often without a second trip to the supply house. Every material is named in your written quote, so you know exactly what’s going onto your house and why.
Common Chimney Repair Problems We See in Marietta Homes
- Cracked clay flue liners in 1950s and 1960s chimneys on original clay tiles. Soil movement and decades of thermal shock separate the tiles, leaving a seam where smoke and carbon monoxide escape into the house structure instead of the atmosphere.
- Spalling or cracked chimney crowns on older homes. The crown is the concrete cap at the top of the stack. Once water penetrates it, the mortar inside softens and you get rusted dampers and soaked fireboxes. This repair is cheap when caught early and costly after a few Georgia winters.
- Animal nesting and creosote buildup in fireplaces that sit unused through Marietta’s mild winters. Squirrels, birds, and raccoons love an uncapped flue. When the first fire of the season hits a nest or heavy creosote, it can flash into a chimney fire.
- Rusted dampers and smoky fireplaces from water running down an exposed flue. On a recent call on Whitlock Avenue, our tech found a hairline liner crack and a damper rusted so badly it could no longer seal. The fix was HeatShield and a new damper, and the smoky smell was gone the next time the fireplace ran.

Here are real numbers for the Marietta market. A chimney cap replacement runs $250 – $550. Mortar repointing and tuckpointing runs $450 – $1,200 depending on the area of brick.

A HeatShield liner repair lands at $900 – $2,200, and a complete DuraFlex stainless liner installation is $2,800 – $4,500.

FAQs About Chimney Repair in Marietta
Start with a Chimney Inspection in Marietta using Level 2 camera technology. For a 1950s brick ranch in Marietta, that means running a camera through the flue to check every clay tile joint. The camera finds hairline cracks and separated mortar you cannot see any other way. The inspection also checks the damper, the crown, and the flashing. You get a photo report showing exactly what was found. If the liner is sound, you walk away with a clean bill. If it’s not, you see the crack in the photo before any repair is recommended. Call (830) 251-4560 and we’ll set up the inspection and give you a written price.
Once a year, and here’s why. Even if you burn only a half-dozen fires each winter, the mild months in Marietta are when animals nest in uncapped flues and moisture sits behind the damper. The National Fire Protection Association standard is that chimneys should be swept when there’s 1/8 inch or more of deposit, but in practice an annual sweep catches nests, cracked crowns, and rusted dampers before they become repair bills. If you’re one of those few-fires-a-year households, an annual sweep is still the cheapest insurance you’ll buy. Our standard sweep in Marietta runs $175 – $275, and the price is written before we arrive.
First-degree creosote is a light, sooty film that sweeps off easily. Second-degree is a granular, flaky deposit that needs more aggressive brushing. Third-degree is a hard, glossy glaze that ordinary brushing won’t remove; it forms when fires burn cool and smolder, which is common in Marietta fireplaces used only occasionally. If a camera inspection shows third-degree creosote, the repair changes because glaze can hide cracks and restricts the flue opening. We will tell you plainly if you have glazed creosote and whether it can be removed by rotary cleaning or whether the liner itself needs attention. Call (830) 251-4560 and we’ll walk you through what your chimney actually has.
You get a written price before any work starts. Not a phone estimate, not a “we’ll see when we get up there.” Every Flint Chimney Sweep visit to a Marietta home includes an inspection with camera, a written quote for any repair found, and your approval before tools come off the truck. If the inspection shows extra damage inside the flue, we stop, show you the photo, and give you a new written price. The number on the invoice is the number you approved. That’s The Garrison Standard, and it applies to every Marietta job, no exceptions.
Here’s our honest answer. A cosmetic mortar hairline crack on an exterior brick can safely wait until spring. A chipped damper handle can wait. Here’s what cannot wait: any crack in the flue liner that lets carbon monoxide into the house, any sign of water actively entering the firebox, and any flue restriction from animal nesting or glazed creosote. Those three are safety issues, not maintenance items. When we find a problem in a Marietta chimney, we’ll tell you which column it falls into. If it can safely wait, we say so and note it in your photo report so there’s a record. Call (830) 251-4560 for a straight answer about your chimney.
