Take measurements of the opening of the frame and subtract 1/16 to 1/8 inch in both directions to ensure that your new pane is a good fit. Cut your replacement glass at a local hardware or glass shop according to this measurement. If you have wooden frames, purchase points for glaziers at a hardware store to install on the edges of your new pane.

The lintel on top of the window can be a source of leaks. The builders who built the house might not have understood the importance of allowing the lintel to drain properly, or have covered it with concrete, leaving a gap through which rainwater can enter and pool around and cause dampness or rot to the wood. The builders may have an angled fascia board above the windows to ensure water is directed correctly. This will prevent water getting into the building.
A gap between the glass panes of a double-glazed windows could also be a source of leaks.

The majority of double-glazed windows feature an "espacer" bar that is placed between the two glass panes. This spacer bar is filled with desiccant, which absorbs any moisture that might occur, therefore preventing it from reaching the glass panes and causing condensation. Unfortunately, this bar can break or crack, and in this case it is often required to replace the entire window.
