Glazing can make a significant difference to the energy efficiency of your home. This is particularly true for older double-glazed windows.

Broken Glass

Windows that are cracked aren't just ugly, but they can also allow valuable heat and sunlight to escape your home. It is possible to repair a broken pane of glass without having to replace the entire window.

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

Glass windows can 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 treated. To prevent stress cracks create an arc of a tiny size with glass cutters close to the crack. This will stop the crack from spreading and slow it down for several days.

If you're replacing a damaged window, measure the frame for the new pane. It should be slightly larger than the opening in order to allow for expansion and contracting, as well as to compensate for any imperfections that may occur on the frame or the glass. After you've cut your glass to size, apply glaziers' compound around the edges of the frame and the glass. After the compound has dried, paint over it to match the frame of the window.

Double Glazed Windows Condensation Inside

Condensation inside double-glazed windows is typically an indication that a seal along 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 prevent heat transfer between the two panes of glass by sandwiching a layer of air or a vacuum between them. This creates a seal that prevents warm air from venting. However, if the glass is colder or colder than the frame, then condensation can accumulate on it and cause damage to the window. If you are unable to remove condensation from a double-glazed window by opening windows, using extractors, using dehumidifiers, or trickle venting, then you might need a professional.

It's less likely to see condensation appear on the outside of double-glazed windows, but it could happen in the event that the seal between the glass and window frame is beginning to break down. This is more prevalent in winter when the temperature is lower, making it more likely for window replacement condensation to form. This is caused by a defect in the spacer used between the frame and the window. This spacer contains desiccant, which is highly absorbent and will absorb any excess moisture.

This could result in moisture seeping through the gap when the desiccant is saturated. This can lead to condensation and water leaking into the gap, and can be very difficult to eliminate.

The positive side is that many trustworthy window manufacturers will provide warranties on their products and should replace the window unit and glass in the event of damage caused by condensation.

It's also an excellent idea to clean the rabbet prior to proceeding with the installation. This is the area around the perimeter of the window replacement frame that is where glass will be. Clean it and then apply the linseed oil to the rabbet, which will allow the new putty to stick securely.

After the frame is cleaned and the rabbet has been prepared It's time to put together the replacement pane. Find the height and width of the opening both ways and then purchase a piece of double-strength glass that's 1/8 inch shorter in both directions. You'll need to purchase glass points which is a steel triangle that keeps the glass in place.

With the window sash removed, use a flat pry-bar to gently pull the sash away from the wood moulding. You may have to scrape old glazing off using a utility blade or chisel. Use the heat gun to warm any putty which won't come off easily. This will make it easier to remove.

Once the frame has been removed from the molding, gently press the glass back into its place. Then, with a putty knife or glazier's point, fill in the gaps around it and smooth them out.
