Basement Finishing & Remodeling
Turn Your Basement Into Living Space
An unfinished basement is wasted square footage. Catalino Quality Construction finishes raw basements and remodels dated finished ones for homeowners across Marietta, East Cobb, Roswell, Milton, and the greater Atlanta metro, turning bare concrete, exposed joists, and worn-out rooms into space your family uses.
Whether you want a guest suite, home office, media room, playroom, or workshop, we handle every phase: moisture mitigation, framing, insulation, electrical, plumbing, drywall, flooring, and trim. One licensed contractor, one point of contact, from start to finish.
Our Basement Finishing Process
1. Assessment & Estimate
We inspect your basement's current condition — moisture levels, ceiling height, existing mechanicals, and access points. You get a written estimate with a clear scope of work and timeline before any commitment.
2. Moisture Mitigation
Georgia's red clay soil holds water. Before any framing goes up, we address drainage, grading, and vapor conditions. This may include interior drain tile, sump pump installation, vapor barriers, or exterior grading corrections. Skipping this step is the most common mistake homeowners make.
3. Framing & Rough-In
Stud walls go up around the perimeter and for interior room divisions. Electrical circuits, recessed lighting, data runs, plumbing rough-ins, and HVAC ductwork are installed and inspected before anything gets covered up.
4. Insulation & Drywall
Rigid foam or fiberglass batts insulate exterior walls. Drywall goes up, gets taped, mudded, and sanded smooth. Ceilings can be drywalled or fitted with a drop ceiling depending on access needs for future maintenance.
5. Flooring & Finish Work
Luxury vinyl plank, tile, or engineered hardwood suited for below-grade conditions. Trim, doors, paint, and any custom built-ins or cabinetry complete the space. If you're adding a bedroom, we install the code-required egress window, including window well excavation.
What We Build in Finished Basements

- Home offices — dedicated circuits, data wiring, and sound insulation
- Media rooms — wiring for surround sound, projection, and dimmable lighting
- Playrooms and rec rooms — durable flooring, open layouts
- Home gyms — reinforced flooring, ventilation, and dedicated electrical
- Wet bars — plumbing, countertops, under-cabinet lighting
- Workshops — heavy-duty circuits, dust collection hookups, and durable surfaces
Basement Conditions in Marietta and Cobb County
Marietta and the surrounding Cobb County area sit on Georgia's Piedmont terrain, which means a wide variety of basement configurations depending on your neighborhood and lot.
Older homes near the Marietta Square and along Whitlock Avenue often have partially below-grade basements with limited natural light. Properties on hillside lots throughout East Cobb — near Johnson Ferry Road, Paper Mill Road, and the communities off Roswell Road — frequently have daylight or walkout basements with direct exterior access, making them ideal candidates for guest suites or bonus living space. Homes in Kennesaw, Acworth, and northwest Cobb County often have full basements that lend themselves to home theaters and recreational rooms.
Regardless of configuration, moisture management comes first. Even basements that appear dry can develop moisture issues once enclosed. We assess drainage, grading, and vapor conditions before any framing goes up, and we address problems at the source rather than covering them with drywall.

Frequently Asked Questions
What's the difference between basement finishing and basement remodeling?
Basement finishing refers to converting a raw, unfinished basement — exposed studs, concrete floors, no drywall — into a livable space. Basement remodeling means renovating a space that was previously finished. If your basement has bare concrete and open joists, you need finishing. If it's already built out but outdated, you need remodeling. We handle both.
How much does it cost to finish a basement in Marietta?
Costs depend on the size of the space, existing conditions, and what you want to build. The scope varies significantly — a basic finish-out with framing, drywall, flooring, and lighting is a very different project from one that includes a bathroom, wet bar, or home theater. The only accurate number comes from a free on-site assessment — we provide a detailed written estimate before any work begins, no surprises.
Do I need a permit to finish my basement?
Yes. Basement finishing requires permits from the local authority: Cobb County for unincorporated addresses (including most of East Cobb), or the city (Marietta, Kennesaw, Smyrna, Roswell) for properties within city limits. Framing, electrical, plumbing, and mechanical work all require permits, and bedrooms require egress windows meeting Georgia building code. We handle all permit applications and inspections as part of the project.
How long does basement finishing take?
Most basement finish-outs take four to eight weeks depending on size and complexity. A straightforward build-out runs four to five weeks, while projects with bathrooms, custom built-ins, or complex electrical take six to eight weeks. We provide a realistic timeline during your free estimate.
Can you finish a basement that has moisture issues?
Yes, but we address the moisture first. Georgia's clay-heavy soil and seasonal rainfall mean many basements need drainage improvements, vapor barriers, or sump pump installation before framing and drywall go in. Fixing moisture at the source protects your investment for the long term.
Do you finish basements in East Cobb?
Yes. East Cobb is one of our primary service areas. We work throughout Marietta, East Cobb, Kennesaw, Smyrna, Acworth, and the broader Cobb County area. Contact us to confirm we serve your neighborhood.
