Glazing Repair - How to Repair a Cracked Window

Glazing can have a major impact on the energy efficiency of your house. This is especially true for older double-glazed windows.

It is possible to change the glazing points by putting the window in place, but it is much easier and faster if you take off the glass and frame. This is also a great opportunity to replace the gaskets on the rubber.

Broken Glass

Cracked glass isn't just unsightly, it can also let valuable heat and sunlight escape from your home. It's possible to fix the glass that is cracked without having to replace the entire window.

Wear safety goggles and gloves. You can also employ duct tape or a painter's tap to create an "X" on the glass that you intend to remove. This will prevent any shattered glass from falling on you as you work.

If you have a small scratch in your window glass, cover it with tape to keep out the elements like wind, water and insects. If the crack is superficial just a single strip of tape will suffice.

Stress cracks are another common issue that can occur to your glass window. They're usually caused by significant temperature fluctuations, and can quickly spread across the entire glass window if not repaired. To stop stress cracks from occurring create a small arc with a glass cutter near the crack. This will stop the crack from spreading and can slow it down by a day or two.

Take a look at the frame of the broken window to determine the size of the new pane. It should be slightly bigger than the opening to allow for expansion and contracting and also to account for any imperfections on the frame or on the glass. Once you've cut the glass to size apply glaziers' compound around the edges of the frame and the glass. After the compound has dried paint it over to match the frame of the window.

Double Glazed Windows Condensation Inside

Condensation inside double-glazed windows is typically an indication that the seal on the window unit has failed. This is a significant issue because it indicates that the heat that is coming from your home is lost through the window, and could be costly for you and your energy bills.

Double glazing has been designed to block heat transfer between the two panes of glass by sandwiching a layer of air or a vacuum between them. This creates an airtight seal and keeps warm air from exiting the home. However, if the glass is colder or colder than the surrounding frame then condensation will build up on it and damage the window. If you're unable to remove condensation from double-glazed windows by opening windows or using extractors, dehumidifiers, or trickle venting, then you might need an expert.

It's much rarer to see condensation appear on the outside of double glazed windows but it can occur in the event that the seal between the glass and the window frame is beginning to break down. It's more frequent in winter, when temperature is lower. This makes it easier for condensation to form. This is caused by an issue with the spacer between the frame and the window. This spacer contains desiccant, which is very absorbent and will absorb any moisture that is present.

The issue is that once the desiccant is saturated, it will begin to break down and moisture can start to enter the gap between the glass units. This can cause water and condensation to build within the gap, which is difficult to clean out.

It is essential to report any issues to your window installer immediately you notice them, so that condensation can be addressed as soon as possible in order to prevent further damage to the window unit as well as the frame surrounding it.

After the frame has been cleaned and the rabbet is prepared, it is time to prepare the replacement pane. Get a piece made of double strength glass that is 1/8 inch smaller in both directions. You'll also need glass points, which are steel triangles which help to hold the glass in the right place.

Replacement Window Glass
