The gap along the bottom of most baseboards is 1/2 to 3/4 inches high. While this gap is unsightly, provides a hiding place for pests and allows dust to filter out of the walls onto the floor, it is also necessary. Not only does it keep the drywall from wicking up moisture from the floor, it allows floor coverings, such as carpet, to be tucked in along the edge. Permanent sealing with caulking products is not the answer. Cover the gap with cover or base shoe moulding for a neat and tidy solution.

Measuring and Marking
Measure from corner to corner of your baseboard moulding, along its bottom edge, using a tape measure.
Use the tape measure to measure along the top edge of the moulding and mark a distance equivalent to the length of the baseboard using a pencil.
Position the moulding on the miter saw, with the bottom on the saw table and the back of the moulding against the saw's fence. Set the angle of the saw for the angle of the corner, a standard 90-degree angle requires two 45-degree angles, one on each of the two pieces that make up the corner.
Cutting and Installing
Align the blade with the mark on the moulding. Position the blade to the left of the mark for a left end cut and to the right for a right end cut. Angle the cut into the face of the moulding for an inside corner, so that the bottom edge is shortest, and away for an outside corner, so that the bottom edge is longest.
Hold the moulding firmly against the table and fence. Start the saw and make the cut in one fluid motion. Allow the saw blade to stop before allowing it to spring back up to prevent chipping.
Fit the moulding piece against the wall so that the mitered ends align to the ends of the wall. Place the moulding firmly on the floor and the back of the moulding against the baseboard to cover the gap. Nail the moulding in place with a pin nail gun and 1 1/2 inch pin nails, one nail every 8 inches.
