Home repair expert Henry Harrison helps a homeowner replace the damaged soffit vents under the eaves of his house. Vents that are damaged can lead to birds and other animals setting up housekeeping in the attic. The repair involves removing the trim around the vents, tearing out the old mesh and replacing it with new. On his elbow grease scale of one to four, Harrison gives this job a two.

Steps:

1. Put on the safety glasses and remove trim using flat bar and hammer (figure A). Gently pry up trim pieces, and insert the pry bar so the gap in the center lines up with any nails.

2. If you plan on reusing the trim pieces, be sure to label them so you'll know exactly where they go when it's time to put them back up.

3. Once trim is out, tear out old mesh using a pry bar or your hands. Also clear out any debris from vents.

4. Use a tape measure to take an accurate measurement for how long the new mesh and, if needed, new trim pieces need to be.

5. The mesh will probably be too wide, so line it up with the paint line on one side so you only have to trim one edge instead for two (figure B). Tack up new mesh with staples, spacing them about six inches apart. The staples are just going to hold the mesh loosely in place until the new trim is installed.

6. Use utility knife to cut of excess trim at end of vent (figure C). Tack up new trim with wire brads or brad nails. Drive nails into ceiling joists, which should be about one foot apart.

7. Use utility knife to cut off excess mesh along trim (figure D). Use the edge of the trim as a guideline for cut.

8. Paint new trim, and be careful not to get paint on the new mesh. This will clog the mesh and the vents will not work as well. Hold a piece of cardboard to the mesh to serve as a shield while painting.
