Glazing Repair - How to Repair a Cracked Window
Glazing can make a significant difference in the energy efficiency of your home. This is particularly important for older double-glazed windows.
While it is possible to change the glazing points when the window is still in place, it is much simpler and quicker if the glass and frame are removed. This is also an excellent occasion to replace the gaskets on the rubber.
Broken Glass
Cracked windows are not only unsightly but can also allow valuable sunlight and heat to escape your home. It is possible to repair a broken pane of glass without having to replace the entire window.
Start by putting on protective gloves and safety goggles. You can also apply duct tape or painter's tape to make an "X" on the glass that you intend to remove. This will prevent any broken pieces from falling when you work, which can save you from serious injury.
Cover a small crack on your window glass using tape to keep water, insects and wind out. One strip of tape should be enough to cover any cracks that are superficial however if you're concerned about the weather becoming worse before you can replace your window, you should use an extra-strong plastic cover like a tarp, or a garbage bag, to hold the glass in place until you get a permanent fix.
For cracks that aren't as shallow, try using a strong adhesive specifically designed for windows, like Loctite Super Glue Glass. This high-tech adhesive is formulated to adhere to glass and then dries crystal clear for a perfect finish. Apply it to the crack and let it dry completely before applying a new layer.
Glass windows may also develop stress cracks. Stress cracks are usually caused by drastic temperature changes and can spread rapidly across the entire window if not repaired. To avoid stress fractures, use a glass cutter to cut a small circle near the crack. This stops the crack from spreading, and can reduce the size by a few days.
Measure the frame of the damaged window to determine the size of the new pane. It should be slightly smaller than the opening to allow expansion and contraction and to cover any imperfections in the glass or frame. After you've cut your new glass to size, apply glaziers' compound around the edges of the frame and the 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 a seal has broken somewhere in the window unit. This is a major issue and could mean that heat is being lost from your home through the window.
Double glazing is designed to prevent heat transfer between two panes by sandwiching an air or vacuum layer between them. This creates a airtight seal and keeps warm air from exiting the house. If the glass is cold or colder than the surrounding frame, condensation will build up on it and damage the window. If you've got condensation on your double-glazed window that you are unable to eliminate it by opening the windows, by using extractor fans, dehumidifiers or trickle venting then you may need to contact a professional.
It's rare for condensation to form on the exterior of double-glazed windows but it can occur if the seal between the glass and window frame has begun to weaken. It is more common in winter, when the temperature is lower. This makes it easier for condensation. The most likely cause is a defect in the spacer that is used between the window and the frame. The spacer usually contains desiccant that is extremely absorbent and will soak up excess moisture.
This could lead to water leaking through the gap after the desiccant is saturated. This can cause condensation and water to build within the gap, which is difficult to remove.
The positive side is that many trustworthy window manufacturers will provide a warranty on their products. They will replace the window unit and glass if it has been damaged by condensation. It's essential to notify your window installer as soon as you spot them so that condensation can be addressed as soon as possible to prevent further damage to the window unit as well as the frame around it.
Shattering Window Glass
A cracked window pane can be more than just an aesthetic problem. It could also be an injury risk, particularly when it's causing. It is best to get it fixed as quickly as you can.

Alternatively, you can make use of a glazing compound formulated for home use, which can be found at a variety of hardware or home improvement stores.
Put on a thick pair of gloves and safety goggles before you begin any work. The area should be swept to remove any large pieces of shards. You should also vacuum any chips. This will prevent them from cutting you or a glazing repair worker later on.
It's better to climb a ladder rather than on the ground. This will allow you to reach all parts of the frame more easily and will protect you from glass falling. Before you begin it's best to clean the rabbet. This is the area where glass will be placed. Apply a coat linseed to the rabbet and wipe it clean. This will aid in helping the putty adhere.
Once the frame is cleaned and the rabbet is prepared, it's the time to prepare for the replacement of the damaged pane. Order a piece of double strength glass that is 1/8 inch smaller in both directions. Also, you'll need to purchase glass points, which are made of metal triangles which keep the glass in place.
With the window sash taken off and the pry-bar flat, use it to carefully pry the sash free of the wood moulding. You may have scrape off old glazing putty with a knife or chisel. Utilize the heat gun to warm any putty that cannot be easily removed. This will make it much easier to remove it.
After the frame is removed from the mold and the frame is pressed gently into the new glass into its place. Then, with the help of a putty knife or glazier's point, fill the gaps around it and smooth the edges. When the putty is dry paint it in a manner that matches the rest of the frame. Paint the glass and the compound by overlapping the paint slightly.

Once the frame is in place, measure it for an entirely new window and buy it from a home improvement store or another retailer. Make sure you order the pane at least 1/6th inch smaller in every direction than the measurement to ensure a snug fit.
Installing the new window is easier than it sounds, but ensure you follow the directions of the manufacturer to ensure right fit and long life for your replacement pane. Use a wire brush to clear the frame of old paint or wood gunk and then sand it to bare wood in order to enhance the seal between the frame and sash.
Make use of the tip of the putty knife when installing the new window to lay it gently against the frame of wood. Press glazier's tips into the frame every six inches. This will hold the new pane firmly in the frame.
