This is regarding a house in Pittsburgh, PA. I just bought my first house and i'm kinda clueless about these things. 1. I need to install a fire-rated door or a solid-core door between the garage and basement. Right now there's a screen door only. I'd need to get a lockset installed. How much will labor and materials be? Is it cheaper to go with Lowes or Home Depot rather than local contractors? 2. The retaining wall is bulging and needs to be fixed. How much would this cost? I was told that the same stones could be reused to rebuild the wall. 3. The house is old and has fuse boxes. I need to get a new circuit breaker panel. Cost? Also have to change the old outlets to grounded ones. 4. I need to regrout the tiles by the tub in the bathroom and recaulk it. The tiles themselves are ok, just need to refinish. I've heard that this shouldn't be too expensive. Does anyone know any reliable contractors? I'm in the South Hills part of town.
