• 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?

  • Nah. Your builders should.

  • 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.
