How to Repair a Double Glazed Window

Double glazing is a cost effective way to increase the insulation of your home and increase its energy efficiency. It is susceptible to problems such as condensation and draughts.

Broken Panes

The first step is to take off the broken pane. Wear thick work gloves, and keep an open box of cardboard close by to catch any shards of glass that fall during you work. Wear a protective eye mask and mask in case of lead being in the frame. Use a utility blade to cut the glazing surrounding the window pane that is broken. Use pliers to remove any nails or clips that are holding the windowpane. After the glass has been removed, remove any old putty and glazing points. If necessary, a heat gun can be used to soften the putty.

Once the old putty is removed Re-grout the grooves and apply a new caulk using a silicone caulking gun. It's a good idea test the fit of the new window inside its frame before applying the final caulking. Make sure that the grooves are free of any gunk, rust or paint, and that they aren't too narrow for the windowpane to sit in.

Replace the sash with a wood moulding to match the windowframe. If the frame of the window is in a poor state it could be easier and more cost effective to replace the entire window unit instead of a single pane.

In the past, double pane windows were made of two pieces of glass, separated with the help of a spacer. They were then filled with either air or an gas for insulation. However, in recent years manufacturers have shifted to insulated glass units (IGs) that are more efficient in energy use and are resistant to seal failure. In upvc window repair with a failed IG moisture from the air outside seeps through the gap and condenses inside the glass. This cycle eventually breaks the insulating properties that are present in the IG and leaves an odourless residue on the glass.

To fix a damaged IG glass, an expert in glass repair can replace the entire unit, or can replace just the broken surface of the glass. This is a lengthy and costly process, but it is the only option to repair a leaky seal that lets water into the home.

Misted Panes

The window frame houses two or more panes of glass, each separated by an air-filled space. The air, which is often filled with argon to improve energy efficiency and to keep warm air in it, helps keep cold air out. Unfortunately, these windows can break down and you may notice a hazy, smoky fog between the glass panes. You might think it's time to replace the entire window however, it's not as simple as simply removing the broken pane and replacing it.

Condensation between the panes is another issue that double-glazed windows may cause. This occurs when the warm air inside your home is warmer than outside air. The difference in temperatures forces the warmer air to expand, which can cause the window's seals to crack or weaken with time.

Double-glazed windows can also cause foggy windows. This is a problem that can be solved without replacing the IGU. This is an indication that your window's seals need to be resealed.
