Glazing Repair - How to upvc repair a Cracked Window

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

While it is possible to replace glazing points when the window is still in place, it is much simpler and quicker when the frame and glass are removed. It is a good idea to replace the seals made of rubber.

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 the glass that is cracked without replacing the entire window.

Wear safety glasses and gloves. You should also place an X-shaped piece of tape an "X" shape on the glass you intend to remove (duct or painter's tape works well). This prevents any shattered pieces from falling as you work, which could protect you from serious injury.

If you've got a tiny scratch in your window glass, cover it with tape to keep out the elements like wind, water and insects. If the crack is only superficial, a single strip of tape will suffice. However, if the weather is likely to get worse before you can replace the window, you may need a more durable plastic cover such as the trash bag or tarp.

Make sure you use a strong adhesive that is specifically designed for windows to fix cracks. Loctite Super Glue Glass is a good option. This high-tech glue is made to bond to glass and it dries crystal clear to give a perfect finish. Apply it to the crack and allow it completely dry before applying a new layer.

Glass windows may also develop stress cracks. They're typically caused by dramatic temperature fluctuations, and they can quickly spread across the entire glass window if not repaired. To prevent stress cracks make an arc using glass cutters close to the crack. This can prevent the crack from expanding and reducing the severity for several days.

If you're replacing an old window, measure the frame for the new pane. It should be slightly smaller than the opening to allow expansion and contraction and to cover any imperfections in the glass or frame. Once you've cut the glass to size, apply glaziers' compound around the edges of both the frame and the glass. Once the compound is dry then paint it over it to match the rest of the window frame.

Condensation on the Inside of Double Glazed Windows

The appearance of condensation on the inside of double-glazed windows typically indicates that the seal has failed somewhere along the window unit. This is a serious issue as it means that heat from your home is lost through the window and can be costly for you and your energy bills.

Double glazing has been designed to prevent heat transfer between the two panes of glass by sandwiching a layer air or vacuum between them. This creates a airtight seal and keeps warm air from exiting the home. If the glass is cold or colder than the frame, condensation will build up on it, which can damage the window. If you are unable solve condensation issues on double-glazed windows by opening windows by using extractors, dehumidifiers or trickle venting, you might require professional help.

Condensation on the outside of double-glazed windows is uncommon however it can happen when the seal has begun to weaken between the glass and the frame. It is more prevalent during winter, when the temperature is lower. This makes it easier for condensation. This is caused by an issue with the spacer that is used between the frame and the window. The spacer is made up of desiccant which is extremely absorbent and will soak up any excess moisture.

The issue is that when the desiccant is saturated, it begins to break down, and local eventually moisture will begin to leak through the gap between the glass units. This could lead to condensation and water leaking into the gap, and can be very difficult to eliminate.

Most reputable window companies offer a warranty and will replace the unit and glass of a window if it is damaged by condensation. Make sure to report any issues as soon as possible to the window manufacturer so that the condensation can be repaired as quickly as possible to prevent further damage.

Shattering Window Glass

A damaged or cracked window can be more than just an aesthetic problem. It could also pose a safety risk, especially when it's spreading. It is best to get it fixed as quickly as possible.

Before you start, it's a good idea clean the rabbet. This is the area that glass is placed. Clean it and then apply an oil coat of linseed to the rabbet. This will help the new putty stick to the frame securely.

After the frame has been cleaned and the rabbet is prepared, it is time to put together the replacement pane. Take measurements of the width and height of the opening both ways Then, you can order the double-strength piece of glass that's 1/8 inch shorter in both directions. You'll need to purchase glass points, which is a metal triangle that holds the glass in place.

With the window sash off the way, gently pry it off of the wood molding using a straight pry bar. You may need to scrape old glazing off with a utility blade or chisel. Make use of the heat gun to warm any putty that cannot be easily removed. This will make it easier to remove it.

After the frame has been removed from the mold then gently press the glass back into its place. Fill in the gaps with a glazier's tip or putty knife. Once the putty has dried paint it to match the frame. Paint the glass and the compound by overlapping the paint slightly.
