rotten floor under pation door
Hi, we have a patio door leading to a deck and the floor in the house is rotten. It seems that the flashing on the bottom of the door on the outside is missing. We have owned the home for 2 yrs now so this has had time to get bad. The florin the kitchen is spongy very close to the door and I am wondering how best to tackle this problem. My thoughts are that the door has to come out and the bad portion of the floor cut out even under the sill and a new small piece put in and supported in the crawl space - with joist sort of setup to hold the new plywood. I do some home improvement but this may be a bit out of my league. Can you give me the proper advice on how to fix this as best as possible with the info given, we will have to decide weather we can tackle this or not.
