Block foundation leaking - can see daylight between blocks
I am considering buying a house that has a concrete block foundation. The basement has some wetness in it from the last heavy rain storm that we had. You can see daylight between some of the concrete blocks. I can't get a contractor to return my phone calls to get an estimate or idea of what it would take to repair the foundation (too much work & not enough contractors in our area - they turn work away).
I know that it's impossible to give me a definite idea as to what I am facing without seeing the basement....but can anyone tell me if this is *likely* going to be a very expensive repair. Can the mortar be replaced from the inside? I assume that waterpoofing from inside is impossible.
I live in the northeast (above Maine) - very cold winters, with lots of snow that melts in spring.
Thanks so much!
