How to stop leak in basement. Beam (sill) that sits on cement basement wall has started to rot allowing rain water to leak into basement when we have heavy rain. The area involved is about 3ft. long. I would say the beam is about 1/4 rotten...for about 6" in the centre of the 3' area. CAn I attempt to fix this myself or should I call in a specalist.

Hi momr,
It isn't that difficult to repair. You will need to take off any pressure that is on the sill. Instead of jacking up the floor use a 4x4 at right angles to the joists and drive a post that is slightly longer than the distance from its bottom to the floor. As you drive the post under the 4x the floor will raise enough to remove the sill. Also you'll need to remove any siding that is on the outside so you can drill a hole to start a reciprocating saw cut. Cut through the sill and remove and then replace with new stock but if it is leaking find the cause before you close everything back up. Caulking will help to stop leaks but the problem may not be in that exact area. Use common sense when tracing down a leak. What causes it, water from above, driving rain, etc. Use PT stock to make your new piece.
Good luck.....Mark Hammond
