Glazing can have a significant effect on the efficiency of your house. This is particularly important for older double-glazed Windows.

Broken Glass

Glass that is cracked isn't just ugly but can also let valuable sunlight and heat escape from your home. It's possible to fix a broken pane of glass without having to replace the entire window.

Cover a small crack on your window glass using tape to keep bugs, water, and wind out.

Glass windows may also develop stress cracks. They are usually caused by large changes in temperature and they can quickly spread across the entire glass window if it's not repaired. To stop stress cracks from occurring make a small arc with glass cutters near the crack. This can prevent the crack from expanding and reducing the severity for a few days.

If you're replacing a damaged window make sure you measure the frame to fit the new pane. It should be slightly larger than the opening to allow for expansion and contracting, as well as to compensate for any imperfections on the frame or on the glass. After cutting your new glass, apply glaziers' compound around the edges of the frame and glass. After the compound has dried then paint it over it to match the frame of the window repairs.

If the glass is colder than the frame, condensation can develop on the glass and cause damage to the window. If you're unable to solve condensation issues on a double-glazed window by opening windows by using extractors, dehumidifiers or repaired trickle venting, you might need an expert.

Condensation on the outside of double-glazed windows is uncommon, but it can occur when the seal has started to break down between the glass and the frame. It's more frequent in winter, when temperature is lower. This makes it easier for condensation. The primary reason for this is a fault in the spacer that is used between the frame and the window. This spacer contains desiccant, which is extremely absorbent and absorbs any excess moisture.

The problem with this is that when the desiccant becomes saturated it will start to break down and moisture will begin to leak through the gap between the glass units. This could lead to water and condensation in the gap, and can be very difficult to get rid of.

Apply a coat of linseed to the rabbet and wipe it down. This will help the putty stick.

Once the frame is cleaned and the rabbet in place, it's time to plan the replacement of the damaged pane. Get a piece made of double strength glass that is one inch smaller in both directions. You'll also need to purchase glass points, which are metal triangles that help to hold the glass in place.

After the putty dries paint it to match the rest of the frame. Lap the paint slightly over the edge of the compound, then onto the glass to seal it completely.
