Basement Finishing & Conversions

An unfinished basement is the cheapest square footage in your house — it already has a roof and walls. We convert basements into bedrooms, suites, media rooms, and legal ADUs, handling the egress, moisture, and ceiling-height issues that make basements tricky.

Basements come with real constraints: egress windows for bedrooms, moisture control, ceiling height, and where the plumbing can go. We solve those first — waterproofing, proper egress, and insulation — then build out warm, dry, code-compliant living space that doesn't feel like a basement.

What's included

• Egress windows and code compliance

  Every basement bedroom needs an egress window or door sized and placed to code; we cut the opening, build the well and make the room legal.

• Moisture control and waterproofing

  We find and fix the water first — grading, drainage, sealing and vapor control — so the finished space stays dry, then insulate for a warm floor and walls.

• Framing, insulation, and drywall

  Framing, insulation and drywall that turn concrete walls into finished rooms, with ceiling height, soffits and ductwork planned around the structure above.

• Bathrooms and wet bars (in-house plumbing)

  Our own plumbers add bathrooms and wet bars below grade, including the ejector pump when the fixtures sit below the sewer line.

• Legal basement ADUs

  A basement apartment with its own entrance, kitchen and bath, permitted as a legal ADU where your city allows it.

• Lighting and mechanical

  Recessed lighting that doesn't eat ceiling height, extended heating and cooling, and the electrical a media room or suite needs.

How it works

1. 1
   Free advice visit

   We check ceiling height, moisture, egress options, where the plumbing can go and what you want the space to do — then leave you a scoped range.

2. 2
   Complimentary 3D model

   The finished basement on your actual plan — rooms, ceiling, lighting — before anything is framed.

3. 3
   Design and permits

   Drawings, egress and energy-code details, structural engineering when the floor is lowered or a beam changes, and the building and trade permits.

4. 4
   Moisture, egress and structure

   Water solved first, egress openings cut, any underpinning or slab work done.

5. 5
   Rough-ins, insulation and drywall

   Plumbing, HVAC and electrical inspected, then insulation and drywall.

6. 6
   Finishes and walkthrough

   Flooring, doors, trim, paint, fixtures and the final inspection.

The same ten-step process runs every project we build — see how we work.

What it costs

Finishing a basement is priced per finished square foot, with the wet rooms, egress and any structural work moving the range the most: a bathroom below the sewer line adds an ejector pump and more plumbing, a bedroom adds an egress window, and lowering the slab for ceiling height is a structural project of its own. Finish level and whether the space becomes a legal ADU with its own kitchen and entrance also set the number.

Timeline

1. Design and permits

   Layout, 3D model, egress and energy-code details, drawings and permits.

2. Water, egress and structure

   Drainage and sealing, egress windows cut and wells built, underpinning or slab work where ceiling height requires it.

3. Framing and rough-ins

   Walls, soffits, plumbing, HVAC and electrical, each inspected.

4. Insulation, drywall and finishes

   Insulation, drywall, flooring, doors, trim, paint, fixtures and lighting, then the final inspection.
