Enclosed breezeway - window problems
My house was built in 1954. Sometime around 1970 the prior owners enclosed the formerly open-air breezeway between the house and garage. They used wood framing in to build walls in the front and back, each with two aluminum louver windows and an aluminum storm door. Last summer I replaced the doors with actual lockable "house entry" doors.
Well, you know how no good idea goes unpunished when you own an old house? When I removed the storm door on the front, I found that water had been leaking inside the wall, probably since the day the wall was built. The framing in 1/2 the wall was rotted almost to dust. I ended up tearing out the entire wall. I framed it with treated lumber and installed the new door and also new windows. Since its an unheated breezeway, I decided to save a little money (famous last words) and use storm windows instead of single or double hung windows. When I replaced the door in the back wall, I also replaced the windows. That wall was sound with no rot.
Now I have two problems:
1. When it rains hard, a thin stream of water now leaks in from the back wall. (Lesson learned: if it ain't broke, don't fix it)
2. Condensation on the inside of the windows. I never had this problem before, with the extremely leaky old windows and doors.
I think one of the windows on the back wall is where the water is getting in. What do I do, sort of tearing off the wall, to fix it?
How do I fix the condensation? Have I made the breezeway too air tight with Thea new windows and doors?
The front wall faces South and the back wall faces North.
I when I did all this work, I threw away all the old trim. I haven't installed new trim yet. I'd like to get these problems fixed before I trim out the windows, doors and baseboards.
I appreciate any advice you can offer!
