how is the best way to install a set of patio doors to a home with a concrete slab?
Do you need to scre the threshold down or can use just a sealer under it? If you have to use masonry screws do you set the door and get it plumb and then drive the screws or do you have to pull the door out and try to set up some anchors under the threshold? The stupid company who made this door doesnt have any instructions on how to install the door with a concrete slab.
first u should have bought a door unit with a adjustable threshold......u can unscrew the top of the threshold and exspose the bottom rail and install the concrete screws..and yes, put a good caulk under the door seal before before this......email me with other questions.......
