Glazing can have a significant effect on the efficiency of your house. This is particularly important for older double-glazed Windows.

It is possible to replace glazing points with the window in place, however it is much simpler and quicker to remove the frame and glass. It is a good idea to replace the seals made of rubber.

Broken Glass

Broken glass isn't just unattractive but it also allows valuable sunlight and heat escape from your home. It is possible to repair a broken pane of glass without replacing the entire window.

Begin by putting on protective gloves and safety goggles. You should also put an X-shaped piece of tape an "X" shape on the glass you plan to remove (duct or painter's tape work well). This will stop any broken pieces from falling while you work, which can keep you from serious injuries.

Cover a small crack on your window glass using tape to keep bugs, water and wind out. One strip of tape is enough for superficial cracks but if you're worried 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 keep the glass in place until you can get a permanent fix.

Make use of a strong adhesive that is specifically designed for windows to repair cracks. Loctite Super Glue Glass is a good choice. This high-tech adhesive is formulated to bond to glass and it dries crystal clear to give an ideal finish. Apply it to the crack, and let it dry completely before applying another layer.

Glass windows may also develop stress cracks. Stress cracks are typically caused by extreme temperature fluctuations and can rapidly spread across the entire window if not repaired. To avoid stress fractures 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 day or two.

Take a look at the frame of the broken window to determine the size of the new pane. It should be slightly bigger than the opening in order to allow for expansion and contraction, as well as to compensate for any imperfections that may occur on the frame or the glass. After cutting the glass, apply glaziers' compound around the edges of the frame and glass. Once the compound is dry paint it in a manner that matches the frame.

Condensation on the Inside of Double Glazed Windows

Condensation inside double-glazed windows is typically an indication that the seal along the window unit has failed. This is a serious problem, as it can mean that heat is being lost from your home through the window.

New double glazing is designed to stop heat transfer between the two panes of glass by sandwiching a layer air or vacuum between them. This creates a airtight seal and stops warm air from escaping the home. However, if the glass is colder or colder than the surrounding frame, then condensation can build up on it, which can damage the window. If you are unable solve condensation issues on double-glazed windows by opening windows or using extractors, dehumidifiers or trickle venting, you might require professional help.

double glazing repair on the outside of double-glazed windows is rare however it can happen if the seal has begun to deteriorate between the glass and the window frame. It is more prevalent in winter, when temperature is lower. This makes it easier for condensation. The primary reason for this is a fault in the spacer that is placed between the window and the frame. The spacer is filled with desiccant which is very absorbent and will soak up any excess moisture.

The issue with this is that once the desiccant becomes saturated it begins to break down, and eventually water can begin to seep through the gap between the glass units. This could cause condensation and water to build up in the gap, which is difficult to clean out.


The majority of reputable window manufacturers provide a guarantee and will replace the glass and unit of a window in the event that it's damaged due to condensation. Report any problems as soon as possible to your window installer so that the condensation is repaired as soon as possible to avoid further damage.

Shattering Window Glass

A cracked window pane isn't just a cosmetic issue, it could also be a security risk, especially if the crack is expanding. It is best to have it fixed as soon as possible. Glass adhesives are available for vehicle windows which you can purchase online or in many auto maintenance shops. Alternatively, you can use a glazing compound intended for use in homes that can be found in a lot of hardware and home improvement stores.

Before starting any work, put on thick protective gloves and safety glasses. Then, sweep the area to get rid of large shards. You should also vacuum any chips. This will stop them from cutting you or a glass repair worker later on.

It is a good idea to work on a ladder instead of standing on the floor. This will allow you to reach all parts of the frame with ease and will protect yourself from glass falling. It's also recommended to wash the rabbet before proceeding, which is the part of the frame around the window frame that is where the glass will go. Clean it and then apply an oil coat of linseed to the rabbet. This will help the new putty stick in place.

After the frame has been cleaned and the rabbet prepared, it's the time to plan the replacement of the damaged pane. Order a piece of double strength glass that is one 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 pull it off of the wood molding with a flat pry bar. It is possible scrape off old glazing using a utility knife or chisel. Utilize the heat gun to warm any putty that won't come off easily. This will make it easier to remove.

Once the frame is free from the molding then carefully press the new glass into its new location. 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. Paint it slightly over the edge of the compound and onto the glass to completely seal it.

Replacement Window Glass

Installing the new window is much easier than you think, however be sure to follow the instructions of the manufacturer to ensure a proper fit and a long life for your replacement pane. Use a wire brush to clear the frame of old paint or wood gunk. then sand it to bare wood in order to enhance the seal between the sash and frame.
