I have one wall in my house that was very cold this last winter. Before we bought this house it had a mouse problem. The wall that was cold is in the kitchen behind the cupboards. The inside walls are plaster.
How or can I add insulation?
I had one person come over and look at the house and he said that I should remove some of the siding, pull out the old insulation then add foam insulation.
Does this sould like a good idea?
will the foam expand and crack my plaster walls?
