# Basement finishing

> Framing, insulation, ceilings and code for finished basements. Ask with your Sheet attached: homeowners who’ve done it and verified pros answer, and anyone can read it.

## Before you ask

The basement’s size, ceiling height, whether it’s ever wet, and your town.

- **Attach your Sheet** so people see your sizes and the math.
- **Your town is enough.** Never your address; check photos for house numbers and plates.
- **Is it safe?** A safety question here goes to pros verified in general contracting or carpentry, unless you pick another trade. Only they can call it safe or unsafe.

## Finish a basement

28′ × 25′ basement: 657 sq ft finished, 108 studs, 36 sheets of drywall and 188 ceiling panels, with foam on the walls.

What people get wrong:

- **Finishing over water.** Every wall you build over a leak is a wall you rip out later.
- **Plastic vapor barrier on the walls.** Poly over foam or behind drywall traps moisture against the wall.
- **Closing walls before the inspection.** Framing and rough-in inspections happen with the walls open.
