Marietta's 1980s and 1990s construction era produced thousands of homes with full unfinished basements — and those basements are now 30–40 years old and at the point where homeowners want to use that square footage. The red clay soil common throughout Cobb County makes moisture assessment critical before any framing goes up.

We've finished basements throughout the 30062, 30066, and 30067 zip codes and know the soil and drainage patterns in this market — which informs how we approach moisture mitigation before the first stud goes in.

What to Expect — Investment Range

Basement finishing in Greater Atlanta ranges from $30,000 for a basic open layout to $75,000+ for a finished suite with a wet bar, bathroom, and dedicated rooms.

Marietta projects typically land in the mid-to-upper portion of that range, reflecting the neighborhood expectations and the quality of finish that protects home values in this market.

Basements with moisture issues must be addressed before finishing — skipping this step leads to mold and costly tear-outs within 2–3 years.

Frequently Asked Questions

How long does a basement project take in Marietta?

Most basement finishing projects take 4–8 weeks. Projects that include a full bathroom or wet bar run on the longer end. Egress window installation can add 1–2 weeks if the opening needs to be cut.

My home is a 1980s colonial in East Cobb — what should I know before starting a renovation?

East Cobb colonials from the 1980s are solid homes, but they carry the hallmarks of their era: galley kitchens, fiberglass bathroom surrounds, aluminum wiring in some cases, and original HVAC systems that may need updating when walls are opened. We always assess these conditions upfront so we can budget accurately and avoid mid-project surprises.

Do you pull permits in Cobb County?

Yes — we handle all permitting for projects in Cobb County. We prepare the documentation, submit the application, schedule all required inspections, and keep you informed at each stage. You don't need to manage the permit process — that's part of what you're hiring us to do.
