Broken Panes

If a window's glass is cracked or broken it allows air to pass more easily, lowering the effectiveness of windows as insulation and barrier against the elements. Depending on the time of year this could cause hot or cold air to escape or enter your home, increasing the cost of cooling and heating.

If the crack in the double glazing isn't very deep, it may be possible to simply apply a strong-hold tape. This is a temporary fix however, and it will only stop the crack from getting worse. To get the most effective results, a professional window repair company is required to fix any damaged glass in double-glazed windows.

Attempting to replace a broken window pane yourself can be challenging and potentially dangerous. If the crack is too big to grasp and hold, try putting strips of masking tape in a crisscross pattern before trying to take it off. If the crack isn't too large you can make use of a razor to remove the glass from the frame. Wear gloves and a mask when cutting the glass. Once the pane is free, you will need to place it flat on several layers of newspaper to keep any pieces that fall.

To install a new pane, you'll need to purchase replacement glass and prepare the frame. To ensure that the new pane fits properly take a measurement of the opening of the window frame and subtract between 1/16 and 1/8 inches on both sides. Cut your replacement glass at a local hardware or glass shop to this measurement. If you have wooden frames, buy points for glaziers from a hardware shop to install on the outside of your new glass. Be sure to position the points in a manner that allows expansion and contraction while still keeping the putty level against the glass.

After your new pane is in place and you are happy with it, apply an even layer of your preferred glazing compound using a putty knife.

Water Leaks

Any water that hits the area should be drained out through the weep holes located in the bottom of the frame. Sometimes, the weep hole may become blocked due to dirt and debris. Also, the weather stripping might need to be replaced.

The lintel on top of the window can also be the source of leaks. The builders who built the house might not have realized the importance of allowing the lintel drain properly, or they could have clad it in concrete, leaving a gap through which rainwater can enter and pool around causing dampness or rot on the wood. The installers should have placed the fascia boards in a slant above the window to ensure that water is directed properly and this will prevent water from getting into the structure through these gaps.

Another possible leak source is the gap that exists between the glass panes in a double-glazed unit. It's possible that the gas argon or krypton that should be positioned between the glass to create insulation has escaped from the windows due to an old seal. Although this is not the most serious issue associated with windows that leak however, it could affect energy efficiency. It is important to address the issue as quickly as possible.

A spacer bar can be found between the two glass panes that are found in the majority of double-glazed windows.

The Insulated Glass Unit (IGU) is comprised of two glass panes, with an area between them, and a rubber gasket that stops water from entering the gap. Certain IGUs contain argon, a gas that prevents heat from escaping the home and saves money on energy costs.
