DIY in the desert
Window leak in desert

My house has 17 picture windows of similar sizes. For the questions below assume that a typical window is 30 by 80 inch. The construction (1976) is as follows: The window frame is 3 ½ by 3 ½ inch wood (clear fir); a 3/16 inch thick glass (one piece) is inset into the middle of the frame and held in place by strips of redwood (very good quality, 3/4 inch thick by 1 ½ inch wide) screwed to the frame. This construction method applies to both sides of the window. The outside bottom strip slopes toward the ground to facilitate drainage. The redwood/glass joint is sealed with silicone caulk. Some of the windows are leaking (the inside wood gets wet). I did a thorough job of repairs in 1997 and I’m looking for less labor-intensive ideas. I’m prepared to remove the silicone seal and repaint the outside in preparation of new repairs but, beyond that, not sure how to get watertight windows. What is the best procedure and materials to achieve a good repair without removing the wood strips (I’m a woodworker so I can add extra custom milled wood, if needed)? How about Geocel vs. silicone?

Re: Window leak in desert

A better product for sealing the outside of the windows is glazing tape. Go on line to order it.
But, if your house is in the desert, where is the moisture from?
