How To: Install a Sill Plate

Building a new home or addition? Here's how to install a sill plate directly onto the foundation.

Here’s how to properly install a sill plate on top of a foundation wall. Sink anchor bolts into your foundation every four feet, laying a sill seal on top of the foundation to create a weather barrier. Pre-drill two-by-six sills to accommodate the bolts. Use pressure-treated lumber to resist water and insect damage. Secure the sill in place with a washer and nut.
