i have a 700 square foot concrete patio that has 12X24 through bodied tile laid on top of it. i want to add some wooden railing around the entire thing with a pergola covering half of it. im pretty comfortable with wood work, but not real sure the best way to attach the railing to the patio as well as to the house? do i need to attach to the house or just the patio? the house is brick if that makes a difference? i assume i will have to drill some type of anchor bolt into the concrete, but whats the best way to drill and attach the posts without cracking the tile? surface mount or mount to the vertical edge of the patio? i had a contractor that was supposed to do the job and has skipped out leaving me to finish...
