I'm new to Home Improvement. I've been planning to start (slowly) finishing my basement myself. The first thing I need to do is tear down the existing ruined insulation and replace it.
I'm trying to find options for 'waterproof' or 'water-resistant' foam insulation panels - there are none at the local Home Depot & Lowes - and I suspect that if I knew what I was doing, there might be better options for where to purchase 'home improvement' supplies.
Any suggestions? Do professionals buy from Lowes & Home Depot? Should I try to find a different local place? How do I find a local business that sells these types of supplies?
