I have 3- 25-year-old double hung vinyl replacement windows that have double-pane low e argon gas units, that leak when it rains. Water leaks at the bottom corner of the bottom sash during heavy rains. The glass units have no condensation. so I don't think I need to replace the double-pane units. It has been suggested that I place a narrow bead of clear silicone on the outside, along the sides and the bottom where the bottom pane meets the frame, as that could be where there is a leak. Note: the weep holes are working. So I think it might be a defective seal between the glass and frame. If that is the case what is the best way to repair that rain leak?
Hi Ken - Thanks for reaching out and we're sorry to hear about your leak. Leaks can be hard to troubleshoot, as water takes a path of least resistance. If you're concerned about a leak between the glass and the frame, a bead of silicone may an option to assess if that's the source of the problem. Then you'll be able to decide what a good long term fix may be for you. Hope that helps.
