Glazing Repair - How to Repair a Cracked Window
Glazing can make a huge difference to the energy efficiency of your home. This is especially true for older double-glazed Windows.

Broken Glass
Broken glass isn't just unattractive but can also let valuable heat and sunlight escape from your home. Fortunately, it's often possible to repair a broken window pane without the need for a complete replacement.
Put on safety goggles and gloves. Also, you should put a piece of tape with an "X" shape on the glass you intend to remove (duct or painter's tape work well). This will stop any broken pieces from falling when you work, which can protect you from serious injury.
If you've got a tiny crack in your window glass Cover it with tape to keep out water, wind, 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, use a heavier-duty plastic cover, such as a tarp or a trash bag, to hold the glass in place until you obtain a permanent fix.
Make sure you use a strong adhesive that is specifically designed for windows to fix cracks. Loctite Super Glue Glass is a good choice. This high-tech adhesive is designed to adhere to glass and dries crystal clear for an ideal finish. Apply it to the crack in the glass, and let it dry completely before applying a new layer.
Glass windows can also develop stress cracks. They're typically caused by dramatic changes in temperature and they can quickly spread across the entire glass window if it's not repaired. To stop stress cracks from occurring, score a small arc with a glass cutter near the crack. This stops the crack from spreading, and can reduce the size by a few days.
If you're replacing an old window, measure the frame for the new pane. It should be slightly bigger than the opening in order to allow for expansion and contracting and to account 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 then paint it over it to match the rest of the window frame.
Double Glazed Windows Condensation Inside
Condensation on the interior of double-glazed windows is typically an indication that a seal around the window unit has failed. This is a serious issue since it means that the heat that is coming from your home is being lost through the window and can be costly to both you and your energy bills.
Double glazing is designed to block heat transfer between two panes, by sandwiching an air or vacuum layer between them. This creates an airtight seal and keeps warm air from exiting the home. If the glass is colder or colder than the frame then condensation will accumulate on it, which can damage the window. If you're unable to resolve condensation on double-glazed windows by opening windows, using extractors, using dehumidifiers or trickle venting, you may require the assistance of professional help.
It's much rarer for condensation to appear on the outside of double glazed windows but it can occur in the event that the seal between the glass and the window frame is beginning to break down. It's more frequent in winter, when the temperature is lower. This makes it easier for condensation. The main cause of this is a defect in the spacer that is placed between the window and the frame. The spacer is often filled with desiccant that is extremely absorbent and can absorb excess moisture.
The issue is that once the desiccant is saturated, it will start to break down and then moisture will begin to enter the gap between the glass units. This can cause water and condensation to build in the gap which is difficult to clean out.
The majority of reputable window manufacturers offer a warranty and replace the unit and glass of the window if it's damaged by condensation. It's essential to notify your window installer when you notice 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 frame surrounding it.

After the frame is cleaned and the rabbet is prepared It's time to put together the replacement pane. Get a piece made of double strength glass that is one inch smaller in both directions. You'll need to buy glass points, which is a metal triangle that holds the glass in place.
With the window sash taken off, use a flat pry-bar to carefully pry the sash off of the wood moulding. It is possible to scrape old glazing off using a utility blade or chisel. Then make use of the heating gun to warm any putty that isn't able to fall off. This will make it easier to peel off.
When the frame is out of the mold and the frame is firmly pressed, gently press the glass in its new location. Then, using a glazier's or putty knife's point, fill the gaps around it and smooth them out. After the putty dries, paint it to match the rest of the frame. Paint the glass and the compound by overlapping it slightly.
Replacement Window Glass

Use a wire brush to clear the frame opening of any old paint or wood gunk, and then sand it down to bare wood in order to improve the seal between the frame and the sash.
When putting the new pane in place, use the tip of your putty knife to gently bed the new window against the wood frame. Press glazier's tips into the frame every six inches. This will hold the new pane securely in position.
After the frame has cured then paint the new joint multiple times to match the frame. Let the paint dry completely before moving on to cleaning and maintaining your window.
