A couple weeks ago we had water in our basement. We called a plumber thinking it was a sump pump failure. That morning the sump pump was working. He said it's standing water. Noticed the water cracks in foundation wall. Concrete in back is sinking which is the wall that had crack.

Looking to finish our basement in the next 12-18 months but recently noticed some rain coming in through basement windows and water damage around the window frames. Before we get the basement finished we wanted to be sure we took care of any water issues.

We have a small area (1ft sq) of moisture in our basement, about 3 years after US Waterseal injected a sealer along a hairline crack in the foundation on the West side of the house where it slopes downhill to the South. We suspect the US Waterseal treatment has failed to some degree. Do you provide trench and rubber seal services for foundations? Thank you......Tony

I've got about a 2x2 wet spot on the carpet in our finished basement, up against an exterior wall. The carpet is damp - not saturated, so I'm not sure how long ago it started - but with the recent rains, I'm not all that surprised. Thanks in advance.
