Question by punkin: 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.

there are no instructions, because you should nto do it yourself if you need to ask on here how to do it
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…….

If you do not secure the bottem of your patio door to the surface it sits on , it will never work properly. Or not as long at least. Can you imagine a train running on a track that wasn’t secure? Come on folks , secure it and do it right. Patio doors are heavy and their track needs to be secured.
You need to put the door where it belongs, mark wear the holes align on the concrete, remove the door frame. Drill out the holes with a concrete bit installed in your drill ( drill with a slow speed ), hammer in lead concrete anchors into the holes so a screw can go through the frame of the door and secure themselves into them.
If you do not do this you will have everything from bugs to air to water coming in under your door frame. Most people change out these doors for insulation values. You will need to seal under the part of the door where the frames meets the concrete with a good adhesive caulk or glue. Do not put in a new door or window and let air creep in around or under it. Waist of time and money.
If you want to do it even better. They make a sticky back rubber material you can lay down on the concrete where the door frames goes. Secure the door frame over it and then cut the excess off from both sides of the track with a razor knife…You can also put this rubber material over the wall surface where the nailing fins of the door frame come into contact with the wood wall , Keeps moisture from having contact with wood surface and stops air infiltration. After putting wood frame around that. Caulk where it meets the wall and also where it meets the door frame. On the inside of the frame fill any gaps between door frame and wall with insulation and then caulk the gap with good adhesive caulk. Creates a dead air space as well as keeping moisture and air out. In my opinion that is the only way to do it. Use quality caulking , not cheap s**t. If you are not replacing a door just because it works poorly but for insulation value as well.
How you install it will make the difference if the room it is in will be cold in a cold area, or warm inside. Reverse in a hot area of the world.The best doors and windows on the market will do you NO GOOD. If not installed properly.
