"Our basement windows leak air as well as water when the snow melts. The house was built in 1965 and the windows seem to exist from that time. They are below the ground level with wells dug out around them. They are set straight into concrete blocks. I looked at different replacement window manufacturers and installers, and none of the ones I saw offering specific windows for basements. Do y'all take any suggestions? (Nosotros aren't planning on doing the replacement ourselves). Give thanks you."
