How to Remount Baseboard Molding

If renovations have left your trim out of place, reposition it with these step-by-step instructions.

Baseboards can end up floating above the floor or partially hidden after flooring has been removed or new drywall has been installed. This project shows you how to remount it the right way.

Materials and Tools:

pry bars
circular saw
vacuum cleaner
power drill
carpenter’s square
utility knife
5-in-1 painter’s tool or putty knife
paint scraper
nail punch
flush-cut saw
caulking gun
whisk broom
knee pads
safety glasses
dust mask


1. Use the painter’s tool or putty knife to cut the paint seam between the baseboard and the wall to make removing the pieces easier.

2. Cut a seam between the baseboard pieces and the drywall with the flush-cut saw.

3. Carefully pry the baseboards away from the wall. Use a hacksaw blade to cut through any small nails you come across.

4. Place thin boards between your pry bar and the drywall to avoid damaging the wall as you go.

5. Clean up the work area with a small broom and a vacuum cleaner. Use a paint scraper to remove layers of old paint on the baseboard pieces, and then sand the pieces till they’re smooth.

6. Cut some short pieces of thin wood to a length equaling the height of the exposure behind the baseboards. Place pieces of double-sided tape on the boards and stick them into place along the exposed areas.

7. Attach the baseboard pieces permanently with finishing nails. Use a nail set to sink the nails below the surface. Run a bead of caulk along the joint between the wall and the top of the baseboards.

8. Since the baseboard now sticks out farther, you may need to cut a couple of new trim pieces. Use scrap lumber or buy lumber to match the existing boards. Use a circular saw to make 45-degree miter cuts on the ends where the new piece comes to a corner.
