Minor basement leak
To give some back ground, our house was built in 1938. It has a level, concrete floor basement with a masonry foundation (ie, rock solid). The basement has always been mostly dry.....some moisture in one of the corners, but the inspector (we purchased 1.5 yrs ago) told us that it's unavoidable on an old house. We cleaned it and applied seal-lock. Problem fixed.
We have had a few downpours of rain over the past few weeks (after not having any in 2 months) and i noticed that there were two wet spots in the basement. One of them is a hairline crack that isn't new, but water seemed to seep up from it. The second area is right around the main plumbing stack where another hairline crack is present.....same issue, water coming up except in this area it appears to be more so.
So, as a first time home owner, what should be my next course of action? Call a basement company? Is there anything I should do immediately? Also, I know I'm probably leaving out some details, but any clue as to what this could be?
Thanks in advance!
