If your Marietta or Roswell home has an older brick chimney, installing the right liner is critical for safety, efficiency, and preventing costly water damage. Stainless steel and cast-in-place liners are the most common upgrades for historic masonry chimneys in metro Atlanta, with costs ranging from $1,200 to $4,500 depending on size and condition. Trust a CSIA-certified chimney sweep with masonry experience to assess your chimney’s needs before lining.
1. Why does my older Marietta brick chimney need a new liner before winter?
Older brick chimneys in Marietta and Roswell were often built without liners or with deteriorating clay tiles that crack under Atlanta’s freeze-thaw cycles. When water enters through Atlanta’s humid summers and cold winter nights, it freezes, expands, and spalls the brick face off your chimney. A liner creates a smooth, sealed flue that prevents exhaust gases from leaking into your home and protects the masonry from moisture damage. Without one, you risk carbon monoxide exposure and accelerated brick deterioration. We inspect chimneys in Marietta every year and see this pattern: homes built before 1980 are most vulnerable. If your chimney hasn’t been relined in the last 15–20 years, it’s time to schedule a CSIA-certified inspection before the first cold snap hits Atlanta.
2. What are the 3 main chimney liner types for Roswell and Marietta homes?
A chimney liner is a protective layer inside your flue that carries exhaust safely out of your home. For older brick chimneys in Roswell and Marietta, the three most common types are:
- **Stainless steel liners (flexible or rigid):** The top choice for older masonry chimneys because they resist corrosion and handle the thermal expansion common in Atlanta’s seasonal swings. Flexible liners snake through existing offsets and bends, while rigid liners suit straight flues and offer longer warranties. Expect to pay $1,200–$3,500 installed, depending on length and gauge. - **Cast-in-place liners (lightweight concrete):** Ideal for severely damaged masonry flues. A foam form is inserted and filled with a cementitious mix that bonds to the existing brick, sealing cracks and restoring structural integrity. Costs range from $2,500 to $4,500 for a typical Atlanta two-story home. - **Clay tile liners (original or replacement):** Only recommended if the existing tiles are intact and properly supported. They’re brittle and prone to cracking in Atlanta’s clay soil movement, so replacement is common after 20–30 years. Budget $800–$2,000 for clay tile relining.
We always recommend a camera inspection before choosing a liner type—Atlanta’s older chimneys often hide surprises behind the brick see our inspection services.
3. How much does chimney liner installation cost in Marietta and Roswell?
Installation costs vary widely based on chimney height, flue condition, and liner type. Here’s a realistic cost breakdown for older homes in Marietta and Roswell:
| Liner Type | Typical Cost Range | Notes | |------------|-------------------|-------| | Stainless steel (flexible) | $1,200–$2,200 | Best for offset flues and moderate damage | | Stainless steel (rigid) | $1,800–$3,500 | Longer warranties, better for straight flues | | Cast-in-place | $2,500–$4,500 | Repairs cracked masonry and restores flue shape | | Clay tile reline | $800–$2,000 | Only if original tiles are intact |

4. What should I look for in a Roswell chimney liner contractor?
Not all chimney contractors are equal, especially when it comes to older brick chimneys in Roswell and Marietta. Look for these non-negotiables:

5. Can I install a chimney liner myself in my Marietta home?
A chimney liner installation is not a DIY project for older homes in Marietta. The risks include improper sealing, carbon monoxide leaks, and voiding your homeowner’s insurance if a fire occurs. Stainless steel liners require precise measurements, proper sealing at the smoke chamber, and secure anchoring at the chimney top. Cast-in-place liners need specialized equipment and expertise to ensure a uniform, crack-free finish. Even if you’re handy, Atlanta’s building codes and CSIA standards require professional installation for safety and compliance. We’ve seen DIY attempts that led to water leaks, structural damage, and costly repairs. Learn what chimney work you can safely DIY in Atlanta.
6. When is the best time to install a chimney liner in Roswell?
The ideal window for chimney liner installation in Roswell is late spring to early fall, before the first cold snap. Atlanta’s humid summers can slow mortar curing for cast-in-place liners, so aim for May through August. Avoid winter installations unless it’s an emergency—cold temperatures can compromise sealants and adhesives. We recommend scheduling your liner installation after a full CSIA inspection and any necessary masonry repairs. If your chimney needs waterproofing or crown repair, those should be completed first to prevent moisture from damaging the new liner. See our summer chimney maintenance tips for Atlanta homeowners.
7. What maintenance does a new chimney liner require in Marietta?
A properly installed chimney liner significantly reduces maintenance, but it’s not maintenance-free. For stainless steel liners, schedule an annual CSIA inspection to check for creosote buildup and seal integrity. Cast-in-place liners should be inspected every 2–3 years for cracks or shifting, especially after Atlanta’s heavy summer storms. Keep the chimney crown and cap in good condition to prevent water entry, and avoid burning unseasoned wood, which increases creosote buildup. If you notice white efflorescence on the brick or a musty smell in your fireplace, it’s a sign water is entering the flue—call for an inspection immediately. Learn more about Atlanta waterproofing for older chimneys.
8. How do I know if my Marietta chimney needs relining or just repairs?
A CSIA-certified inspection is the only way to know for sure. During the inspection, we use a chimney camera to assess the flue’s condition. Signs that relining is needed include cracked or missing clay tiles, excessive creosote buildup, or a flue that’s too large or too small for your appliance. If the masonry is sound but the liner is damaged, relining is the best solution. If the brickwork is crumbling or the chimney is leaning, we’ll recommend masonry repairs first. Many Marietta homeowners assume their chimney just needs sweeping, but a camera inspection often reveals hidden damage.

Frequently Asked Questions
My 1950s brick chimney in Marietta has white stains on the bricks. Does it need a liner or just waterproofing?
Those white stains are efflorescence, a sign your chimney is absorbing moisture. While waterproofing can help, it’s not enough if your flue is damaged or unlined. We recommend a CSIA inspection with a camera to check the flue’s condition. If the liner is cracked or missing, relining is the safer long-term fix. Waterproofing alone won’t stop exhaust gases from leaking into your home.
Why does my Roswell fireplace smell like campfire even when I’m not using it?
That persistent campfire smell is likely creosote or soot trapped in your flue. Older chimneys in Roswell often have rough, unlined flues that absorb odors. A stainless steel liner smooths the flue and reduces odor buildup. If the smell lingers after sweeping, it’s time for a camera inspection to check for hidden creosote deposits or a damaged liner.
Can I use my fireplace this winter if my Marietta chimney hasn’t been relined in 20 years?
No. A 20-year-old unlined chimney in Marietta is a fire hazard. The clay tiles likely have cracks that allow heat to escape into the brick, risking a chimney fire. The Chimney Safety Institute of America recommends relining before using the fireplace. Schedule a CSIA inspection and reline before the first cold night.
I’m buying a 1920s bungalow in Roswell. What chimney questions should I ask during the inspection?
Ask for a CSIA Level 2 inspection with a chimney camera. Specifically, inquire about the flue’s condition, whether it’s lined, and if the masonry needs repointing or crown repair. Also ask about waterproofing and the chimney’s clearance to nearby trees or structures. Older Roswell homes often have hidden damage—don’t skip the camera inspection.
