Philadelphia: what's the rule regarding insulation?
Hello everyone,
I wasn't sure where to post this, but here's my situation. I'm currently in the process of rehabbing a house in Philly. It's an interior unit row home with basement, 1st floor and 2nd floor. Got all my permits. Inspector from L&I came out and said that the front and back walls need to be insulated. So I noted that and after he left, I realized that in the basement, I will be taking down the interior drywall, but one the 1st and 2nd floors, drywall will be placed on top of the existing drywall.
After the inspector left, I tried calling him, but I can't get in touch with him, so I thought I would ask someone here. I have 2 questions:
1. Since I will be removing existing drywall in the basement, I'm sure I have to insulate the walls before I put new drywall down. But what about 1st and 2nd floors? I'm not removing the existing drywall. Should I still insulate them?
2. Inspector told me that whomever does the insulation, they need to provide a certificate that it was properly done. I know I can rent a machine that blows insulation from Home Depot. Obviously, there will be no certificate if I do it myself. Do I have to hire a company to insulate the walls? Can I do it myself?
Those of you with experience, please point me in the right direction. Dealing with L&I in Philly is an absolute nightmare.
Thanks in advance.
