Step 1

Measure Wall
The first step is to measure the wall. If you are measuring from a section of the wall that has trim on one end and a corner on the other, measure from the edge of the trim to the corner. Measure twice to make sure your measurements are accurate. You want to be precise to a 16th of an inch.
Step 2

Cut Baseboard to Length
Using a miter saw, make your cut on a 45 degree angle. If you are using a compound miter saw, reverse your angle to cut the next piece. If you are unable to do that, flip the next piece to cut it.
Step 3


Cope Baseboard
If you are cutting baseboard for an inside corner, put your pieces up together and see how well they fit (Image 1). If it is not a tight fit, you may want to cope the baseboard. Using a coping saw, cut out the miter at a back angle to create a negative cut (Image 2). The cut piece should fit perfectly around the non-cut piece.
Step 4

Install Baseboard
Install baseboard using a nail gun. Put two nails in the baseboard every 4 or 5 inches.
