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 in older double-glazed windows.

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

Broken Glass

Windows that are cracked aren't just unattractive, but also allow valuable heat and sunshine to escape your home. Fortunately, it's possible to repair a damaged window pane without having to go through a full replacement.

Begin by putting on protective gloves and safety glasses. You can also apply duct tape or painter's tap to create an "X" on the glass you plan to remove. This will prevent any shattered glass from falling on you as you work.

Cover a small crack in your window with tape to keep insects, water and wind out. If the crack is superficial, a single strip of tape will be enough. However should the weather be expected to worsen 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 specifically designed for windows to repair 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 the perfect finish. Apply it to the crack and allow it dry completely before applying another layer.

Glass windows can also develop stress cracks. Stress cracks are typically caused by drastic temperature changes and can rapidly spread across the entire window if not addressed. To prevent stress fractures using a glass cutter, you need to score a small arc close to the crack. This will stop the crack from spreading, and may slow it down by a day or two.

Measure the frame of the damaged window to determine the size of the new pane. It should be slightly larger than the opening in order to allow for expansion and contraction and also to make up for any imperfections that may occur on the frame or on the glass. After cutting your glass, apply glaziers' compound around the edges of the frame and glass. Once the compound has dried paint it in a manner that matches the frame.

Double Glazed Windows Condensation Inside

Condensation on the interior of double-glazed windows is usually an indication that a seal along the window unit has failed. This is a serious issue and could mean that heat is being lost from your home through the window.

Double glazing is designed to block heat transfer between two panes, by sandwiching an air or vacuum layer between them. This creates an airtight seal that stops warm air from escaping the house. But, if the glass is cold or colder than the frame, then condensation can build up on it and cause damage to the window. If you've got condensation on your double-glazed window and you cannot resolve it by opening the windows, by using extractor fans, dehumidifiers or by trickle venting then you may need to contact a professional.

Condensation on the outside of double-glazed windows is not common however it can happen when the seal has started to weaken between the glass and the window frame. This is more common in winter when the temperatures are lower and it's more easy for condensation to develop. The main cause of this is a fault in the spacer that is placed between the window and the frame. This spacer often contains desiccant that is extremely absorbent and will soak up excess moisture.

The problem with this is that once the desiccant becomes saturated it begins to break down and moisture can start to enter the gap between the glass units. This could cause condensation and water to build within the gap, which is difficult to clean out.

Most reputable window companies offer a warranty and replace the glass and unit of the window if it's damaged due to condensation. It's essential to notify your window installer immediately you notice them so that condensation can be addressed as quickly as possible to avoid further damage to the window unit as well as the frame around it.

Shattering Window Glass

A damaged window isn't just a visual issue, it could also pose a security risk, especially if the crack has been spreading. It's best to have it repaired as quickly as you can. You can use glass adhesives for windows in vehicles that can be purchased on the internet or in many auto maintenance shops. You can also apply a glazing compound for use at home that is available at a variety of hardware and home improvement stores.

Before you begin any work, wear thick cut-proof gloves and safety glasses and sweep the area to eliminate large shards. You should also vacuum any chips. visit website will prevent them from causing injury to you or a glass repair technician later on.

It's better to climb a ladder rather than on the ground. This will allow you to reach all parts of the frame and protect you from falling glass. Before you begin it's important to clean the rabbet. This is the area that the glass will be placed. Clean it off and then apply an oil coat of linseed to the rabbet. This will allow the new putty to stick securely.

After the frame has been cleaned and the rabbet prepared It's time to make the replacement pane. Take measurements of the width and height of the opening both ways and then purchase an item of double-strength glass that is 1/8 inch shorter in both directions. You'll need glass points which is a metallic triangle that holds the glass in place.

With the window sash removed from the way, carefully pry it off of the wood molding using a straight pry bar. It is possible to scrape off old glazing with a knife or chisel. Then you can use the heat gun to warm any putty that won't easily be removed. This will make it much easier to remove it.

Once the frame has been free of the molding then carefully press the glass in its new location. Then, with the help of a putty knife or glazier's point, fill the gaps around it and smooth the edges. When the putty is dry, paint it to match the rest of the frame. Paint the glass and the compound by overlapping it slightly.

Replacement Window Glass

If you're replacing a broken window, be sure to wear eye protection and gloves to shield yourself from glass shards. Tape the area around the window to prevent it from breaking once you take it off.

Use a utility blade 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 coat linseed to make sure the new glue sticks better.

Once the frame has been constructed, take measurements to determine the dimensions of a new windowpane. Then, you can purchase it at an home improvement store or another retailer. Make sure you order the pane 1/6th inch shorter in every direction than the measurement to allow for an ideal fit.

Installing the new window is easier than you think, however make sure you follow the manufacturer's directions to ensure a correct fit and a long-lasting life for your replacement pane. Use a wirebrush to remove any paint or wood gunk from the frame's opening. Then sand the wood until it is the bare wood in order to improve the seal.

When you are putting the new window in place, use the point of your putty knife and gently place the window on the frame made of wood. Then, press glazier's facets into the frame approximately every six inches to keep the window securely in place.

After the frame has cured, paint the new joint several times to match the frame. Let the paint completely dry before you begin cleaning and maintaining your window. Maintaining windows in good condition and ensuring they function properly will increase their lifespan and increase the energy efficiency of your home. If your windows are outdated or in poor condition it is possible that you would be better off with a full window replacement. If you decide to go with this option, we suggest choosing a high-quality, insulated window to cut down on your energy bills. The type of window that you choose will also affect the overall cost of your project.
