If the crack is small enough that you can keep it in place and use a razor blade to cut it off from the frame. Wear gloves and a mask while cutting the glass. After removing the glass and laid flat, you can place it on several layers of newspapers to catch any pieces that may fall.

To install a new glass pane, you will need to purchase replacement glass and set up the frame. To ensure that your new pane fits properly take a measurement of the opening of the window frame and subtract between 1/16 and 1/8 inch on both sides. Then, have the replacement glass cut according to this measurement at your local glass shop or at a hardware store. If you have wooden frames, buy points for glaziers from a local hardware store to be positioned along the edge of your new glass.

Water Leaks

Water leaks around a window's frame or sash are a typical problem. This occurs when the window sealant is worn out and needs to be replaced. Water leaks around the window can cause damage to the plaster or drywall and lead to damp walls.

Or, the weather stripping could need to be replaced.

The lintel that is above the window could also be the source of leaks. The builders who constructed the house may not have understood that the lintel needs to be allowed to drain properly, or they may have simply clad it with concrete leaving an opening where rainwater could enter and pool around the window causing dampness in the wall or wood rot. The installers could have angled fascia boards above the windows to ensure water is directed correctly. This will stop water from getting into the building.

A gap between the glass panes of a double-glazed windows could also be a source of leaks. A damaged seal could have caused the gas argon or krypton which is supposed to be in between the glass panes to provide insulation to leak out.

The most evident evidence of condensation is the appearance of droplets of water forming on the glass's surface. These droplets will rapidly evaporate when the window is heated by sunlight.

Most double glazed windows have spacer bars that sit between the two panes of glass. The spacer bar is filled with desiccant that absorbs any moisture and prevents it from reaching the glass. Unfortunately, this spacer bar can sometimes break or crack and in this situation, it is often required to replace the entire window.

The Insulated Glass Unit (IGU) is composed of two glass panes that have an opening in between and a rubber gasket which stops water from entering the gap. Some IGUs contain Argon, a gas that stops heat from escaping the home and saves money on energy costs.

If one of the IGUs is damaged, an alternative pane can be purchased from a window manufacturer and then fitted to the frame. This is typically less expensive than replacing the whole window and is more cost-effective for most households.
