How to Lay Sleeper Joists on an Uneven Floor

Inspect your floor to determine if it is level. An uneven floor may require the installation of sleeper joists to create a level surface for your flooring material.

Step 2: Gather Materials

You will need the following materials:

- Sleeper joists (typically 2x4 or 2x6 lumber)

- Wood screws or nails

- A level

- A drill or hammer

- Shims

Step 3: Prepare the Floor

Remove any existing flooring material and underlayment. Clean the subfloor to remove any debris.

Step 4: Install the Sleeper Joists

Lay out the sleeper joists in a perpendicular pattern, spacing them evenly according to the manufacturer's recommendations for your flooring material.

Place shims under the joists in any low spots to level them.

Secure the joists to the subfloor using wood screws or nails.

Step 5: Check the Level

Check the level of the sleeper joists using a level. Make any necessary adjustments by adding or removing shims.

Step 6: Install the Flooring Material

Install your chosen flooring material over the sleeper joists, following the manufacturer's instructions.

Step 7: Secure the Flooring

Secure the flooring to the sleeper joists using nails or screws, or by using a nailer or stapler.

Step 8: Finishing Touches

Inspect the edges and corners of the flooring to ensure they are flush. If any gaps exist, fill them with a suitable filler or sealant.

Install any baseboards or other trim pieces as desired.
