What this covers
A finished basement adds living space, but only if the space stays dry. The work begins with a moisture and drainage check, then egress windows where bedrooms are planned, framing, insulation, electrical and any plumbing, drywall, ceilings, flooring suited to below-grade use, and lighting. Permits and inspections apply to most of it.
When to call
- An unfinished basement that stays dry and could become a family room, office or bedroom.

Questions people ask
What is an egress window?
A window large enough to climb out of in an emergency, with a well outside it. Codes require one in any basement bedroom.
What flooring works in a basement?
Floors that tolerate moisture and cool temperatures: luxury vinyl plank, tile, sealed concrete, or carpet over a proper subfloor system. Solid hardwood is usually avoided.
What about radon?
Finishing a basement makes it a living space, so a radon test before the work is sensible. A mitigation system can be added if needed.
