Hello I'm new here and I've just had a garage built 18 x22. I came to garage journal to look at ideas on finishing the garage. It is not complete yet. We are waiting for the electrician. So I have not moved in it yet. I have no finished walls and was not looking to do that. Is it necessary? I live in Wisconsin with lots of snow. It is basically for the 1 car and storage. Also looking at storage ideas- I was thinking of pegboard. Is this good for non drywalled garage?
