Floor joists are an important part of any floor. They help support the foundation and make the floor solid. Learning how to install floor joists properly is very important for your home.
When choosing boards to be the floor joists, it’s important to use a high-quality grade of wood and to make sure it's free from defects such as knots. This will ensure the wood’s strength is at its full potential. Stick to 2x6, 2x8, or 2x10 or thicker. Anything less won't offer enough support.
When installing the floor joists, lay them out every 16”. Make sure they're against a bearing wall.
Crucial Floor Joist Installation Tips
