Learn how to seal wall cracks and leaks. Get tips on how to patch up moisture cracks in your basement walls and prevent new leaks from forming.
LESLIE: Robert in Utah needs some help in the basement . What’s going on? Tell us about the problem.
TOM: Well, sure. I mean, you certainly could use a good quality caulk  on that crack; like a white silicone adhesive caulk or something of that nature. The issue here is probably the drainage outside that wall.
LESLIE: Mm-hmm. I mean and you even mentioned, Robert, that it occurs if your sprinklers are on too long or if you get a rain.
TOM: Mm-hmm. Yeah. So I think you ought to take a look at the grading and the drainage at the outside foundation perimeter. Make sure that the soil is sloping away from the wall and, with respect to the rain, make sure that your gutters  and downspouts are clean and that if you have a spout discharging anywhere near there, that you extend it out least four feet.
ROBERT: But I could use just a regular silicone caulk on the inside and that would hold?
TOM: (overlapping voices) Yeah, absolutely. There’s no reason you can’t. It’s nothing special; just a masonry block wall. And basically, what water is doing is simply finding the path of least resistance. So you can seal that and you could repaint the wall and you’ll be good to go.
ROBERT: OK, well, thank you very much. Appreciate your help.
TOM: You’re welcome. Thanks so much for calling us at 888-MONEY-PIT.
