Was just trying to make it and the laundry room less of an eye sore to sell it, as well as add some insulation in for the next couple/few winters that I own it.
That sums up every project I have ever started. You always find what you dont expect, and its always super expensive or labor intensive to fix it seems.
For your foundation, make sure the grading outside the house is good for proper drainage. That seems to be the cause of many problems, including some at my place. I have a rubble stone wall below grade with bricks on top, and the bricks are starting to become unhappy. Time to call in the mason who likes to work on old stuff... I'm sure it won't be cheap.
