Glazing can make a huge difference to the energy efficiency of your home. This is particularly true for older double-glazed windows.

Broken Glass
Windows that are cracked aren't just unattractive, but also let 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.
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 tap works well). This prevents any shattered pieces from falling as you work, which could protect you from serious injury.
Cover a small crack in your window glass with tape to keep bugs, water, and wind out. If the crack is only superficial, a single strip of tape will suffice. However should the weather be expected to worsen before you can replace the window, you might want to use a heavy-duty plastic cover like a trash bag or tarp.
For cracks that aren't quite as shallow, try using a strong adhesive that is specifically designed for windows, such as Loctite Super Glue Glass. This high-tech glue was designed to adhere to glass and dry clear to give a perfect finish. Apply it to the crack and let it dry completely before applying a new layer.
Stress cracks are another common problem that can happen to your glass window. They are usually caused by large temperature fluctuations, and can spread quickly across the entire glass window if they aren't repaired. To stop double glazing repair near me from occurring, use a glass cutter to cut a small arc close to the crack. This can prevent the crack from spreading and can slow it down for some 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 for expansion and contraction, and to cover any imperfections in the frame or glass. Once you've cut the glass to the proper size apply glaziers' compound around the edges of the frame and the glass. After the compound has dried, paint over it to match the frame of the window.
Double Glazed Windows Condensation Inside
The appearance of condensation on the interior of double-glazed windows typically indicates that a seal has broken somewhere along the window unit. This is a major issue because it 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 putting an air or vacuum layer between them. This creates a airtight seal and stops warm air from escaping the house. However, if the glass is colder or colder than the surrounding frame, then condensation can build up on it and 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 by trickle venting, then you may require the help of a professional.
Condensation of the outside of double-glazed windows is not common However, it could happen when the seal has begun to weaken between the glass and the window frame. It is more common during winter, when the temperature is lower. This makes it easier to create condensation. The primary reason for this is a defect in the spacer that is used between the window and the frame. The spacer is often filled with desiccant which is highly absorbent and will soak up excess moisture.
The issue is that when the desiccant becomes saturated it will begin to break down and then moisture will begin to leak through the gap between the glass units. This could cause condensation and water to build in the gap which is difficult to remove.
Most reputable window companies provide a guarantee and will replace the unit and glass of the window if it's damaged by condensation. It is essential to notify your window installer immediately you notice them so that the condensation can be repaired promptly in order to prevent further damage to the window unit as well as the frame around it.

Once the frame is cleaned and the rabbet ready, it's time to prepare for the replacement of the broken pane. Purchase a piece of double strength glass that is 1/8 inch smaller in both directions. You'll need to buy glass points which is a metallic triangle that keeps the glass in place.
With the window sash off the way, carefully pry it away from the wood molding with a straight pry bar. You may have to scrape old glazing off using a utility knife or chisel. Utilize the heat gun to warm any putty which won't come off easily. This will make it easier to remove.
