joist support

  1. Building & Construction
    I am in the process of extending my living room into my garage and we had a nice surprise when we removed the wall between the two rooms. There was a bulkhead attached perpendicular to the wall that I thought was just for asthetics but it seems was supporting a double 2x12 floor joist and...
