Hi:

There are a few trickles of water coming into my unfinished basement because of the huge Mid-Atlantic snow storms that we have had. The water is coming in from the upper corner where the ceiling meets the wall that faces the outside. It is happening for the first time, and my guess is that it is because of the unchatracteristic amount of snow that's now melting.

Is fixing this leak from the inside of the basement an option? I have heard of polyurethane foams (available in Home Depot) that can actually be used even if the water is trickling through the cracks. Is this something I can do myself?

Please advise.

Thanks,
K
