I've just bought a 7 year old house in San Antonio, TX. The home has (what I thought was) nice Lincoln wood windows. OK, I guess I do like them, but I have a problem ... Wife and I noticed a puddle on the ground floor concrete block (we have stained concrete floors) in the dining room. This is right in front of full wall height windows. Water was coming from above. Above the windows in the dining room is a large steel I-beam. Above that is the master bedroom windows ... More full height windows. Anyway, I inspected the outside and there appears the previous owner had the same problem because he installed aluminum flashing on the I-beam. This doesn't seem to be the problem, though. There is a vertical strip of wood between the center large window and one of the narrower side windows that is apparently warped outward at it's upper edge. It actually protrudes slightly, maybe a quarter inch, beyond the horizontal wood strip above it. I'm guessing I need to remove this strip and replace it, reseal it, and repaint it. Should I get a pro to do this repair?
Another thing I'm concerned about ... The wood at the bottom of this vertical strip is extremely crumbly. I broke it apart with my fingers and it is extremely dry and blackish in color. Is this black mold that I should be concerned about and is this dry rot? I'm thinking that I should spray the leaking area with Jomax/Bleach combo to kill any potential mold.
Any help is appreciated.
I've also got a Home Warranty for one year ... I'm not sure this is covered ... I'll have to check on it.
