Glazing Repair - How to Repair a Cracked Window
Glazing can have a significant impact on the energy efficiency of your home. This is especially true in older double-glazed windows.
While it is possible to change the glazing points when the window is in place, it's faster and simpler when the frame and glass are removed. This is also a good chance to replace the rubber gaskets.
Broken Glass
Cracked glass isn't just unsightly, it can also let valuable sunlight and heat escape your home. Fortunately, it's possible to repair a broken window pane without the need for a complete replacement.
Start by putting on protective gloves and safety goggles. You can also employ duct tape or a painter's tap to create an "X" on the glass you want to remove. This will prevent any broken pieces from falling as you work, which could save you from serious injury.
If you've noticed a small scratch in your window glass you can cover it with tape to block water, wind, and insects. One strip of tape is enough for superficial cracks however if you're concerned about the weather becoming worse before you can replace your window, consider using a more durable plastic cover such as a tarp or a trash bag, to hold the glass in place until you can obtain a permanent fix.
For cracks that aren't as deep Try using a strong adhesive designed specifically for windows, like 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 a new layer.
Glass windows can also develop stress cracks. They're typically caused by dramatic changes in temperature and can spread quickly across the entire glass window if it's not repaired. To avoid stress fractures that result from stress, use a glass cutting tool to cut a small circle close to the crack. This prevents the crack from spreading, and can slow it down by a few days.
Measure the frame of the broken window to determine the size of the new pane. It should be slightly bigger than the opening to allow for expansion and contracting and also 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. After the compound has dried, paint it to match the frame.
Double Glazed Windows Condensation Inside
The appearance of condensation on the inside of double glazed windows usually indicates that the seal has been damaged somewhere in the window unit. This is a significant issue as it means that the heat that is coming from your home is being lost through the window and can be costly for you and your energy bills.
Double glazing is designed to stop heat transfer between two panes by putting an air or vacuum layer between them. This creates a tight seal that stops warm air from venting. If the glass is colder than the frame, condensation could form on the glass and cause damage to the window. If you have condensation on your double-glazed window that you are unable to eliminate it by opening the windows using extractor fans, using dehumidifiers or by trickle venting, you might require the help of an expert.
It's rare for condensation to appear on the exterior of double-glazed windows but it can happen if the seal between the glass and window frame has begun to weaken. It's more frequent in winter, when temperature is lower. This makes it easier to create condensation. The main cause of this is a defect in the spacer placed between the frame and the window. The spacer usually contains desiccant that is extremely absorbent and will soak up excess moisture.
This could result in moisture leaking into the gap after the desiccant has been saturated. This can cause water and condensation to build in the gap which is difficult to remove.
The good news is that most reputable window companies will offer warranties on their products. They should replace the window unit and glass in the event of damage caused by condensation. It is crucial to notify your window installer as soon as you notice them, so that condensation can be addressed as quickly as possible to avoid further damage to the window unit and the frame around it.

After the frame has been cleaned and the rabbet ready, it's time to get ready for the replacement of the broken pane. Order a piece of double strength glass that is one inch smaller in both directions. You'll need glass points, which is a metal triangle that holds the glass in place.
With the window sash taken off using a flat pry-bar to gently pry the sash off of the moulding of wood. You may have to scrape old glazing off with a utility blade or chisel. Utilize the heat gun to warm any putty that isn't able to be removed easily. This will make it much easier to remove it.
Once the frame has been removed from the molding then gently press the new glass in its place. Fill in the gaps with a glazier's tip or putty knife. Once the putty is dry paint the frame to match. Paint the glass and the compound by overlapping it slightly.
Replacement Window Glass

Use a wirebrush for removing any paint or wood gunk from the frame opening. Then sand the wood to the bare wood in order to increase the seal.
Use the point of the putty blade when installing the new window to bed it lightly against the wood frame. Then, press glazier's points into the frame every six inches to hold the new window firmly in the frame.
