Glazing Repair - How to Repair a Cracked Window
Glazing can make a significant impact on the energy efficiency of your home. This is particularly true for older double-glazed windows.
While it is possible to replace glazing points while the window is in place, it's quicker and easier to do so if the frame and glass are removed. It is a good idea to replace the seals made of rubber.
Broken Glass
Cracked windows are not only unsightly but can also allow valuable sunlight and heat to escape your home. It's possible to fix a broken pane of glass without having to replace the entire window.
Begin by putting on your protective gloves and safety glasses. You should also place a piece of tape with an "X" shape on the glass you intend to remove (duct or painter's tape works well). This will stop any broken glass from falling on your work surface as you work.
Cover a small crack on your window with tape to keep bugs, water and wind out. If the crack is only superficial, a single strip of tape will suffice. However in the event that the weather is expected to worsen before you can replace the window, you may prefer a sturdy plastic cover, such as a trash bag or tarp.
For cracks that aren't quite as shallow Try using a strong adhesive designed specifically for windows, such as Loctite Super Glue Glass. This high-tech glue is designed to attach to glass and then dry clear to give a perfect finish. Apply it to the crack, and let it completely dry before applying another layer.
Stress cracks are another frequent issue that can occur to your glass window. They're typically caused by dramatic changes in temperature, and they can quickly spread across the entire glass window if not fixed. To stop stress cracks from occurring, score an arc of a tiny size with a glass cutter near the crack. This will prevent the crack from spreading and slow it down for some days.
If you're replacing an old 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 and also to account for any imperfections on the frame or on the glass. After you've cut your new glass to size apply glaziers' compounds around the edges of both the frame and the glass. Once the compound is dry paint it to match the frame.
Condensation on the Inside of Double Glazed Windows
Condensation on the interior of double-glazed windows is usually an indication that a seal around the window unit has failed. This is a serious issue, as it can indicate that heat is being lost from your home through the window.
Double glazing is designed to prevent heat transfer between two panes by putting an air or vacuum layer between them. This creates a tight seal that blocks warm air from escaping. If the glass is cooler than the frame, condensation will form on the glass and cause damage to the window. If you've got condensation on your double glazed window and you cannot resolve it by opening the windows, by using extractor fans, dehumidifiers, or by trickle venting then you may need to contact a professional.
Condensation on the exterior of double-glazed windows is not common, but it can occur when the seal has started to weaken between the glass and the window frame. It is more prevalent in winter, when temperature is lower. This makes it easier for condensation to form. The main cause of this is a flaw in the spacer placed between the frame and the window. The spacer is often filled with desiccant that is highly absorptive and absorbs excess moisture.
The issue is that once the desiccant gets saturated, it will begin to break down and moisture can start to enter the gap between the glass units. This could cause condensation and water to build up in the gap, which is difficult to remove.
Most reputable window companies offer a warranty and will replace the unit and glass of the window if it is damaged by condensation. It is essential to notify your window installer as soon as you spot them so that condensation can be fixed as soon as possible in order to prevent further damage to the window unit as well as the surrounding frame.

This will allow the new putty to stick to the frame securely.
After the frame is cleaned and the rabbet prepared, it is time to prepare the replacement pane. Measure the height and width of the opening in both directions, then order an item of double-strength glass that is 1/8 inch shorter in both directions. You'll need to buy glass points, which is a metal triangle that holds the glass in the right place.
After removing the window sash using a flat pry-bar to gently pry the sash free of the moulding of wood. It is possible to scrape old glazing putty off using a utility blade or chisel. Then you can use the heat gun to warm any putty that doesn't be removed. This will make it easier to peel off.
Once the frame has been removed from the mold and the frame is pressed gently into the glass back into its place. Fill in the gaps with a glazier's tip or putty knife. After the putty has dried, paint the frame to match. Lap the paint slightly over the edge of the compound and onto the glass to completely seal it.
Replacement Window Glass

Use a wire brush to clean the frame of old paint or wood gunk, and then sand it down to bare wood to enhance the seal between the frame and sash.
When putting the new pane in place, use the tip of your putty knife to gently lay the new window against the frame made of wood. Then, press the glazier's points into the frame approximately every six inches to keep the window securely in the frame.
