10 Quick Tips About Glazing Repair
Glazing Repair - How to Repair a Cracked Window

Glazing can have a major impact on the efficiency of your home. This is especially important in older double-glazed windows.

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

Broken Glass

Cracked windows aren't just unsightly but can also allow valuable heat and sunshine to escape your home. It is possible to repair a broken pane of glass without replacing the entire window.

Put on safety goggles and gloves. You can also apply duct tape or painter's tape to make an "X" on the glass you want to remove. This will prevent any shattered glass from falling on your work surface as you work.

Cover a small crack in your window glass using tape to keep bugs, water and wind out. If the crack is superficial just a single strip of tape will be enough. However, if the weather is expected to worsen before you can replace the window, you may prefer a sturdy plastic cover, such as a trash bag or tarp.

For cracks that aren't quite as shallow, try using a strong adhesive designed specifically for windows, such as Loctite Super Glue Glass. This high-tech adhesive is designed to bond to glass, and dries crystal clear for an ideal finish. Apply it to the crack and let it completely dry before applying another layer.

Glass windows may also develop stress cracks. Stress cracks are typically caused by drastic temperature changes and can quickly spread across the entire window if they are not fixed. To stop stress cracks from occurring, score an arc of a tiny size with glass cutters close to the crack. This will stop the crack from spreading and slow it down for a few days.

Take a look at the frame of the damaged window to determine the size of the new pane. It should be slightly larger than the opening to allow for expansion and contracting and to account for any imperfections in the frame or on the glass. Once you've cut your glass to 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

Condensation inside double-glazed windows is usually an indication that a seal along the window unit has failed. This is a significant issue because it indicates that heat from your home is lost through the window and can be costly to both you and your energy bills.

Double glazing is designed to stop heat transfer between two panes, by sandwiching an air or vacuum layer between them. This creates an airtight seal and keeps warm air from exiting the home. However, if the glass is cold or colder than the surrounding frame, then condensation can build up on it and damage the window. If you're unable to resolve condensation on a double-glazed window by opening windows or using extractors, dehumidifiers, or trickle venting, then you might require the assistance of a professional.

It's less likely for condensation to appear on the outside of double glazed windows, however it can happen in the event that the seal between the glass and frame is beginning to break down. It is more common during winter, when the temperature is lower. This makes it easier for condensation to form. The primary reason for this is a flaw in the spacer that is placed between the window and the frame. The spacer is filled with desiccant which is extremely absorbent and absorbs any moisture that is present.

The issue is that when the desiccant gets saturated, it will begin to break down and moisture will begin to seep through the gap between the glass units. This can lead to condensation and water in the gap, and can be very difficult to get rid of.

The good news is that most reliable window companies will provide an assurance on their products. double glazing repairs should replace the glass and window unit in the event of damage caused by condensation. Inform any issues as quickly as possible to the window manufacturer to ensure that the condensation is repaired as quickly as possible to avoid further damage.

Shattering Window Glass

A damaged or cracked window could be more than an aesthetic issue. It could also pose an injury risk, particularly if it is spreading. It's best to get it fixed as soon as possible. Glass adhesives can be used for window glass in your vehicle that you can buy on the internet or in numerous auto maintenance shops. You can also make use of a glass compound designed for home use and can be purchased at a variety of hardware or home improvement stores.

Put on a thick pair of gloves and safety goggles before you begin any work. The area should be swept to remove any large shards. You should also vacuum any chips. This will stop them from cutting you or a glass repair person later on.


It is better to stand on a ladder than on the ground. This will let you access all parts of the frame with ease and will protect your glass from falling. Before you begin it's important to clean the rabbet. This is the area where the glass will be placed. Apply a coat linseed to the rabbet and wipe it down. This will aid in helping the putty stick.

After the frame has been cleaned and the rabbet is prepared It's time to prepare the replacement pane. Purchase a piece of double strength glass that is 1/8 inch smaller in both directions. You'll need to purchase glass points which is a metallic triangle that holds the glass in the right place.

With the window sash off the way, carefully pry it off of the wood molding using a flat pry bar. You may need scrape off old glazing putty with a knife or chisel. Then, use the heat gun to warm any putty that won't easily come off. This will make it easier to peel it off.

When the frame is out from the molding then carefully press the new glass into the frame. Fill in the gaps using either a glazier's tipped or a knife. Once the putty has dried paint it in a manner that matches the rest of the frame. Paint the glass and the compound by overlapping the paint slightly.

Replacement Window Glass

If you're replacing a damaged window, be sure to wear eye protection and gloves to shield yourself from glass shards. Tape off the area surrounding the broken window to prevent it from shattering again in a different area when you remove it.

Make use of a utility knife to cut off the old glazing compound from the wood frame and glazing points (small triangles of metal). Clean the entire opening of the frame and then apply a layer of linseed to aid in adhering the new putty better.

After the frame is prepared, measure it to determine the size of the new windowpane. Then purchase it at a home improvement retailer or other retailer. Make sure to order the pane at least 1/6th inch smaller in each direction than your measurement to allow for an ideal fit.

It's not as difficult as you think to install the new window. However, it is essential to follow the guidelines provided by the manufacturer to ensure a proper fit and a long-lasting 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 increase the seal between the frame and sash.

When you are putting the new window in place, use the tip of your putty knife and gently lay the new window against the frame made of wood. Then, press glazier's points into the frame about every six inches to keep the new window firmly in place.

Once the frame is cured, paint the new joint several times to match the frame. Let the paint completely dry before cleaning and maintaining your windows. Maintaining your windows in good condition and ensuring that they function properly will increase their lifespan and increase the energy efficiency of your home. You may want to replace your windows if they are older or in poor condition.
