I am very satisfied with the corrective work done by Rocklin Glass & Mirror, Inc. (RGM) to modify a leaky frameless shower door, installed several years ago by a different company. The problem causing water leaks underneath the door is that the tile curb does not tilt towards the shower basin as it should, but was constructed perfectly flat. RGM technicians recommended and installed a higher dam strip than I already had, a new shower door sweep and a new door strike. These improvements completely eliminated water leaks underneath the shower door! I highly recommend this company.
