My builders have installed new (aluminum, sliding) windows. I’ve noticed they haven’t sealed off between the window frame and the window sill, at the bottom. Should I be running the silicon gun along this gap?
Ask them about it. It might be there to let water out, depending on the design of the window and frame. Wouldn't do it myself until I was sure there was no purpose to it.
