Glazing Repair - How to Repair a Cracked Window
Glazing can make a huge impact on the energy efficiency of your home. This is especially true for older double-glazed Windows.
It is possible to replace the glazing points by putting the window in place, but it is much easier and quicker if you remove the frame and glass. This is also an excellent opportunity to replace the gaskets on the rubber.
Broken Glass
Cracked glass isn't just unsightly, it can also let valuable heat and sunlight escape your home. Fortunately, it's often possible to repair a damaged window without having to go through a full replacement.
Start by putting on protective gloves and safety goggles. You should also put a piece of tape in an "X" shape on the glass you intend to remove (duct or painter's tape works well). This will stop any broken glass from falling onto your work surface as you work.
Cover a small crack on your window with tape to keep bugs, water, and wind out. One strip of tape should be enough to cover any cracks that are superficial but if you're worried about the weather getting worse before you can replace your window, you should use a heavier-duty plastic cover, such as a tarp or a trash bag, to keep the glass in place until you can get a permanent fix.
Use a strong adhesive that is designed for windows to fix cracks. Loctite Super Glue Glass is a great choice. This high-tech glue was designed to attach to glass and then dry transparent to give a perfect finish. Apply it to the crack in the glass, and let it dry completely before applying another layer.
Stress cracks are another frequent issue that can occur to your glass window. They are usually caused by large temperature fluctuations, and can quickly spread across the entire glass window if it's not fixed. To stop stress fractures from occurring, use a glass cutter to cut a small circle close to the crack. This prevents the crack from spreading and may slow it down by a day or two.
If you're replacing a broken window take measurements of the frame to determine the size of the new pane. It should be slightly bigger than the opening in order to allow for expansion and contraction and also to account for any imperfections in the frame or on the glass. After cutting your new glass, apply glaziers compound around the edges of the frame and glass. After the compound has dried paint it over to match the rest of the frame.
Condensation on the inside of Double Glazed Windows
Condensation inside double-glazed windows is usually an indication that a seal along the window unit has failed. This is a serious problem because it could indicate that heat is lost from your home through the window.
New double glazing is designed to block heat transfer between the two panes of glass by sandwiching a layer of air or vacuum between them. This creates a tight seal that stops warm air from escaping. 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 and you are unable to resolve it by opening the windows, by using extractor fans, dehumidifiers or by trickle venting then you may need to contact a professional.
It's less likely to see condensation appear on the outside of double-glazed windows but it can occur when the seal between the glass and frame has begun to weaken. It's more frequent in winter, when temperature is lower. This makes it easier for condensation to form. The most likely cause is a fault in the spacer placed between the frame and the window. The spacer is filled with desiccant which is extremely absorbent and absorbs any excess moisture.
The issue with this is that when the desiccant is saturated, it will begin to break down, and eventually water can begin to enter the gap between the glass units. This can lead to water and condensation in the gap, and can be very difficult to eliminate.
The majority of reputable window manufacturers offer a warranty and replace the glass and unit of the window if it's damaged by condensation. Make sure to report any issues as soon as possible to your window installer so that the condensation is repaired as quickly as possible to prevent further damage.
Shattering Window Glass
A cracked window pane is more than an aesthetic issue. It can also pose an injury risk, particularly when it's spreading. It is best to get it fixed as quickly as you can.

It's a good idea to work from a ladder, instead of standing on the floor. This will allow you to reach all parts of the frame and will keep you safe from falling glass. Before you begin it's best to clean the rabbet. This is the area that the glass will be placed. Wipe it down and then apply a coat of linseed oil to the rabbet, which will allow the new putty to stick securely.
After the frame is cleaned and the rabbet has been prepared, it is time to put together the replacement pane. Find the height and width of the opening both ways Then, you can order the double-strength piece of glass that is 1/8 inch smaller in both directions. You'll also need to purchase glass points, which are steel triangles which help to hold the glass in the right place.
With the window sash taken off, use a flat pry-bar to gently pull the sash away from the moulding of wood. You may have to scrape off old glazing with a knife or chisel. Then, use the heating gun to warm any putty that isn't able to come off. This will make it easier to remove it.
After the frame is removed from the mold, gently press the new glass into its place. Fill in the gaps using a glazier's tip or putty knife. After the putty has dried, paint the frame in a similar color to the putty. Lap the paint slightly over the edge of the compound, then onto the glass to seal it completely.
Replacement Window Glass

It's easier than you think to install a new window. However, it's important to follow the instructions given by the manufacturer to ensure a proper fit and long-lasting replacement pane. Use a wirebrush for removing any old paint or wood gunk from the frame opening. Then sand the wood down to the bare wood in order to improve the seal.
When you are putting the new window in place, use the tip of your putty knife and gently place the window on the wood frame. Put glazier's tips in the frame every six inches. This will keep the new window securely in place.
When the frame is cure, paint the joint with a few coats of paint to match the rest of the frame. Let the paint completely dry before cleaning and maintaining your windows.
