A professionally finished basement adds desirable living space without expanding the home's footprint.

The Finishing Process

Framing and Insulation

We begin by framing the walls and ceiling to create the basic structure. Our team uses pressure-treated lumber for the bottom plates to prevent moisture damage. We install proper insulation to improve energy efficiency and comfort.

Electrical and Plumbing

Our licensed electricians install new circuits, outlets, and lighting fixtures according to San Francisco building codes. We plan the electrical layout to ensure adequate power for your intended use of the space.

Drywall and Painting

Once framing, insulation, and rough-ins are complete, we hang and finish drywall. Our skilled technicians tape, mud, and sand the walls and ceilings to create a smooth surface.
