Glazing Repair - How to Repair a Cracked Window
Glazing can have a significant effect on the energy efficiency of your home. This is especially important in older double-glazed windows.
It is possible to change the glazing points by putting the window still in place, but it is much easier and quicker if you remove the frame and glass. It is a good idea to replace the seals made of rubber.
Broken Glass
Cracked glass isn't just unsightly but it also allows valuable heat and sunlight escape from your home. Fortunately, it's possible to fix a broken window pane without having to go through a full replacement.
Wear safety glasses and gloves. You should also put an X-shaped piece of tape an "X" shape on the glass you plan to remove (duct or painter's tape work well). This will prevent any shattered glass from falling onto you while you work.
If you've got a tiny scratch in your window glass you can cover it with tape to keep out the elements like wind, water and insects. One strip of tape should be enough for superficial cracks however if you're concerned about the weather becoming worse before you can replace your window, you should use a more durable plastic cover like a tarp, or a garbage bag, to hold the glass in place until you obtain a permanent fix.
Use an adhesive that is strong and specifically designed for windows to repair cracks. Loctite Super Glue Glass is a good option. This high-tech glue was designed to adhere to glass and dry transparent to give a perfect finish. Apply it to the cracks in the glass and allow it to dry completely before applying a second layer.
Glass windows may also develop stress cracks. They're typically caused by dramatic changes in temperature, and can quickly spread across the entire glass window if it's not treated. To stop stress fractures from occurring that result from stress, use a glass cutting tool to cut a small arc close to the crack. This will stop the crack from spreading and slow it down for several days.
Measure the frame of the damaged window to determine the size of the new pane. It should be slightly bigger than the opening in order to allow for expansion and contracting and to make up for any imperfections on the frame or on the glass. After cutting the glass, apply glaziers' compound around the edges of the frame and glass. Once the compound has dried paint it in a manner that matches the frame.
Double Glazed Windows Condensation Inside
The appearance of condensation on the interior of double glazed windows usually indicates that the seal has failed somewhere in the window unit. This is a major issue because it could indicate that heat is being lost from your home through the window.
New double glazing is designed to prevent heat transfer between the two glass panes by sandwiching a layer of air or vacuum between them. This creates a tight seal that stops warm air from escaping. If the glass is warmer than the frame, condensation can form on the glass and cause damage to the window. If you've got condensation on your double-glazed window that you are unable to eliminate it by opening the windows, using extractor fans, using dehumidifiers or trickle venting then you may need to contact a professional.
It's much rarer for condensation to appear on the exterior of double-glazed windows, however it can occur when the seal between the glass and frame is beginning to break down. It is more common during winter, when the temperature is lower. This makes it easier for condensation. This is caused by an issue with the spacer used between the frame and the window. The spacer usually contains desiccant which is highly absorbent and will soak up excess moisture.
The problem with this is that when the desiccant is saturated, it begins to break down and moisture will begin to seep through the gap between the glass units. This could lead to condensation and water in the gap, which is difficult to eliminate.
Most reputable window companies provide a guarantee and will replace the unit and glass of a window if it is damaged by condensation. It is essential to notify your window installer immediately you notice them, so that the condensation can be repaired as quickly as possible to prevent further damage to the window unit as well as the frame surrounding it.
Shattering Window Glass

It is better to stand on a ladder than on the ground. This will let you access all parts of the frame with ease and protect your glass from falling. It is also recommended to wash the rabbet prior to starting, which is the part of the frame around the window frame where the glass will go. Wipe it down and then apply the linseed oil to the rabbet. This will help the new putty stick securely.
After the frame has been cleaned and the rabbet prepared, it's the time to prepare for the replacement of the broken pane. Get a piece made of double strength glass that is one inch smaller in both directions. Also, you'll need to purchase glass points, which are steel triangles that hold the glass in place.
With the window sash out of the way, gently pry it away from the wood molding with a flat pry bar. You may have scrape off old glazing with a knife or chisel. Use double glazing Lewisham to warm any putty which isn't able to be removed easily. This will make it much easier to peel it off.
After the frame has been removed from the mold and the frame is pressed gently into the new glass 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. Paint the glass and the compound by overlapping it slightly.

When you're putting the new pane in place, use the tip of your putty knife and gently place the window on the frame of wood. Then, press the glazier's points into the frame approximately every six inches to hold the new window securely in the frame.
When the frame is cured, coat the joint with a few coats of paint to match the rest of the frame. Let the paint dry completely before proceeding to cleaning and maintaining your window.
