# Siding

> Vinyl, fiber cement and wood siding. Ask with your Sheet attached: homeowners who’ve done it and verified pros answer, and anyone can read it.

## Before you ask

The wall area, the siding you want, and what’s under the old siding.

- **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.

## Install or replace siding

40′ × 25′ house, 2 stories: 22.7 squares of siding (+10% → 13 boxes), 3 rolls of house wrap, 31 pieces of J-channel and 8 corner posts.

What people get wrong:

- **Vinyl nailed tight.** It can’t move with the heat and buckles in summer.
- **No gap at the channels.** Panels jammed into J-channel ripple when they grow.
- **Skipping the window flashing.** Water runs behind new siding at every window and rots the wall for years before it shows.
