I apologize for those who saw this message on the Decks listing. It should have been posted to this one.

We bought our house three years ago (built in the 1960s in California. It has a west facing sliding glass door that opens on to an overhanging deck. It has had leakage problems in the past, which caused the prior homeowner to spend $10,000 to repair dry rot under the floor. We have been using silicon sealent to keep the water out with pretty good results. However, the door seems to lack a proper flashing, and in the last storm where wind driven rain blew in from the West we actually had water filling up our door runners, in the house (soaked it up with a towel). We just had a new hardwood floor put in and the prior damage was repaired, so we don't want this to happen again. Any suggestions? A friend suggested replacing the sliding doors with French doors. Another said we should just rip out the whole thing and have it redone. How much would that cost? Thanks.

could be a couple thousand or even more.

One problem is not only the door, but it could be that there is no drainage plane controlling water in the wall above the door so that any water penetrating the siding finds it's way to the door head and then in, even with a good door.

Thank you for the reply. Well as far as the siding goes. A prior handyman had used silicon sealent to seal around the door frame up to the door lintel and around the bottom where it connects to the deck. That seemed to keep out the water. So I really do think the water is coming in, only when the storms blow against the glass door. When I sealed the area below the door frame with silicon sealent that seemed to work. Perhaps the runner frame is not allowing for proper drainage, which would account for why it filled up so easily. This only happens with hard driving rain blowing against the glass - not often. In gentle rain coming straight down there seems to be no problem. I have about a foot overhang over the door which seems to keep that rain away. I guess what I need to know is how should a door like this be installed? Would a different type of door be better? What does it need? And is there a place where I can go to look at a picture of how this should be done? Thanks.

I forgot. In Piffin's reply he/she mentioned wall plainage. I have a flat roof (a new one at that) and the drainage moves toward the back of the house, so I don't think it is coming in from the roof. It really does seem to be coming in from both sides of the doors. In the past, before I sealed it with silicon, wet spots emerged just inside both ends of the door on the floor, but not in the middle of the door. Perhaps the entire frame shoudl be removed and reinstalled with proper sealing?
