re: Water along walls of my basement... cause/fix?

Sorry, long day. Thanks for the input. The home is a rental (not in Cali anymore, so not the quake), and the walls are drywall. It is a split-level home.

The property manager had a company come and do water removal. They left fans under the carpet and want them to keep running until Monday.

It’d be hard to tell where it is wet because of the color of the carpet, as there is no standing water. I think the curtain drain comment may be onto something... the house was built in the 60s. Hopefully it isn’t a huge project, I really don’t want the wife to have to deal with folks in/around the house while I am gone for a few weeks.

Would it be reasonable to negotiate a rent decrease if this happens again/frequently?
