Hi,
I have two doors in the house that leak. One is a side garage door, a simple aluminum frame door. The other is the basement patio sliding door. Doors are 18 yrs old. Both doors leak around the bottom corners of the frame in moderate to heavy rain. I suspect that the sliding door has a broken seal somewhere in the channel. I noticed leaks last year, and this summer went around with lots of caulking, but it didn't fix the problem.
My question is, is there a relatively simple fix (flashing, weather guard) that I can use to protect the doors from leaking ?
Also, can the sliding door (aluminum frame door that slides in a channel) be re-sealed, or am I better off just buying a new one ?
