Broken Glass
Cracked glass isn't just unsightly, it can also let valuable heat and sunlight escape from your home. It is possible to repair a broken pane of glass without replacing the entire window.
Wear safety goggles and gloves. You should also put a piece of tape in an "X" shape on the glass you plan to remove (duct or painter's tape work well). This will stop any broken glass from falling onto you while you work.
Cover a small crack on your window glass using tape to keep water, insects and wind out. If the crack is only superficial, a single strip of tape is enough. However, if the weather is expected to worsen before you can replace the window, you may need a more durable plastic cover such as a trash bag or tarp.

This high-tech glue is designed to adhere to glass and dry clear for a flawless finish. Apply it to the crack in the glass and allow it to 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 they are not repaired. To stop stress fractures from occurring using a glass cutter, you need to cut a small circle near the crack. This stops the crack from spreading and can slow it down by a few days.
If you're replacing an old window make sure you measure the frame to fit the new pane. It should be slightly smaller than the opening to allow for expansion and contraction and to compensate for any imperfections in the frame or glass. After you've cut your glass to size apply glaziers' compounds around the edges of both the frame and the glass. After the compound has dried paint it to match the frame.
Double Glazed Windows Condensation Inside
Condensation inside double-glazed windows is usually an indication that the seal on the window unit has failed. This is a significant issue as it means that the heat that is coming from your home is being lost through the window, and could be costly for you and your energy bills.
New double glazing is designed to prevent heat transfer between two glass panes by sandwiching a layer of air or a vacuum between them. This creates a seal that blocks warm air from escaping. If the glass is cold or colder than the frame, condensation will build up on it and window replacement cause damage to the window. If you notice condensation on your double glazed window and you cannot resolve it by opening the windows, using extractor fans, using dehumidifiers or window replacement by trickle venting then you may need to contact an expert.
Condensation of the outside of double-glazed windows is uncommon, but it can occur when the seal has started to break down between the glass and the window frame. This is more common in winter, when the temperatures are lower and it's easier for condensation to form. This is caused by an issue with the spacer used between the frame and the window doctor. The spacer is often filled with desiccant that is highly absorptive and will soak up excess moisture.
The issue with this is that once the desiccant gets saturated, it will start to break down and then moisture can start to enter the gap between the glass units. This could cause condensation and water to build within 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 notice them, so that the condensation can be repaired as quickly as possible to prevent further damage to the window unit and the frame surrounding it.

Before you start it's important to clean the rabbet. This is the area that glass will be placed. Apply a coat of linseed on the rabbet and then wipe it clean. This will help the putty adhere.
After the frame has been cleaned and the rabbet is in place, it's time to plan the replacement of the broken pane. Order a piece of double strength glass that is 1/8 inch smaller in both directions. You'll also need to purchase glass points, which are steel triangles which hold the glass in the right place.
With the window sash removed using a flat pry-bar to gently pry the sash away from the wood moulding. You may have to scrape old glazing off using a utility blade or chisel. Then make use of the heating gun to warm any putty that doesn't come off. This will make it much easier to peel it off.
Once the frame has been removed from the mold and the frame is pressed gently into 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 the paint slightly.
Replacement Window Glass
If you're replacing a broken window pane, you should first wear eye protection and gloves to protect yourself from glass shards. Tape the area around the window to prevent it from breaking again when you take it off.

Once the frame is ready, make sure you measure it to get the new window pane. Then purchase it from a home improvement store or other retailer. Be sure to purchase the pane one-sixth inch shorter in every direction than the measurement to allow for an ideal fit.
Installing the new window is simpler than you think, however be sure to follow the manufacturer's directions to ensure a correct fit and a 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, which will enhance the seal between the frame and sash.
