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

Glazing can make a big difference to the energy efficiency of your home. This is particularly important for older double-glazed Windows.

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

Broken Glass

Windows that are cracked aren't just unattractive, but also allow valuable heat and sunlight to escape your home. It is possible to repair the glass that is cracked without replacing the entire window.

Put on safety goggles and gloves. You should also put an X-shaped piece of tape an "X" shape on the glass you intend to remove (duct or painter's tape work well). This will prevent any broken glass from falling on your work surface as you work.


If you have a small scratch in your window glass Cover it with tape to keep out water, wind, and insects. One strip of tape is sufficient for cracks with a superficial appearance however if you're concerned about the weather getting worse before you can replace your window, use an extra-strong plastic cover like a tarp or trash bag, to hold the glass in place until you can find a permanent solution.

Make use of an adhesive that is strong and specifically designed for windows to repair cracks. Loctite Super Glue Glass is a good choice. This high-tech glue was designed to bond to glass and dries clear to give a perfect finish. Apply it to the cracks in the glass and allow it to dry completely before applying a second layer.

Stress cracks are another frequent issue that can occur to your glass window. Stress cracks are typically caused by extreme temperature fluctuations and can spread rapidly across the entire window if they are not repaired. To avoid stress fractures using a glass cutter, you need to score a small arc close to the crack. This will prevent the crack from spreading and can slow it down for several days.

Measure the frame of the damaged window to determine the size of the new pane. It should be slightly smaller than the opening to allow expansion and contraction and to cover any imperfections in the frame or glass. After cutting the glass, apply glaziers' compound around the edges of the frame and glass. After the compound has dried paint it in a manner that matches the frame.

Double Glazed Windows Condensation Inside

The appearance of condensation on the interior of double-glazed windows typically indicates that the seal has failed at some point along the window unit. This is a serious problem because it could mean that heat is being lost from your home through the window.

Double glazing is designed to prevent heat transfer between two panes by putting an air or vacuum layer between them. This creates a airtight seal and prevents warm air from leaving the home. But, if the glass is cold or colder than the surrounding frame then condensation will form on it, which can damage the window. If you have condensation on your double-glazed window and you cannot resolve it by opening the windows with extractor fans, using dehumidifiers, or by trickle venting, then you may require the help of an expert.

Condensation on the exterior of double-glazed windows is not common however it can happen if the seal has begun to break down between the glass and the window frame. It is more prevalent during winter, when the temperature is lower. This makes it easier for condensation to form. The primary reason for this is a fault in the spacer that is placed between the frame and the window. The spacer is made up of desiccant which is extremely absorbent and will absorb any moisture that is present.

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

Most reputable window companies offer a warranty and replace the unit and glass of a window if it's damaged by condensation. Make sure to report any issues as soon as you can to the window manufacturer so that the condensation is repaired as soon as it can to avoid further damage.

Shattering Window Glass

A cracked window pane isn't just an aesthetic issue, it could also be a security risk, especially if the crack has been expanding. It is recommended to get it repaired as soon as you can. You can use glass adhesives for windows in vehicles that can be purchased online or in many auto repair shops. You can also make use of a glass compound designed for use at home 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 start any task. The area should be swept to get rid of any large shards. You should also vacuum any chips. This will prevent them from causing injury to you or a glazing repair technician later on.

It is a good idea to work from a ladder, instead of standing on the ground. This will enable you to reach all the parts of the frame with ease and protect yourself from glass falling. Before window repairs Croydon start it's important to clean the rabbet. This is the area where glass is placed. Apply a coat of linseed to the rabbet, then wipe it clean. This will help the putty adhere.

After the frame has been cleaned and the rabbet in place, it's time to prepare for the replacement of the broken pane. Purchase a piece of double strength glass that is 1/8 inch smaller in both directions. You'll also need to purchase glass points, which are metal triangles that hold the glass in place.

After removing the window sash and the pry-bar flat, use it to gently pry the sash free of the moulding of wood. You may have to scrape old glazing off with a utility blade or chisel. Make use of the heat gun to warm any putty which won't come off easily. This will make it easier to remove.

Once the frame has been removed from the molding then gently press the glass back into its place. Fill in the gaps with the glazier's tip or a putty knife. Once the putty has dried, paint it to match 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 pane, first wear eye protection and gloves to protect yourself from glass shatters. Tape the window's edges to stop it from breaking when you take it off.

Begin by removing the old glazing compound and glazing points (small metal triangles) from the wood frame using a knife. Clean the frame opening and then apply a coat linseed to help the new putty adhere better.

Once the frame has been made, measure it to determine the dimensions of a new windowpane. Then, you can purchase it at an home improvement store or other retailer. Be sure to purchase the pane one-sixth inch shorter in every direction than the measurement to ensure a snug fit.

Installing the new window is easier than you think, but make sure you follow the instructions of the manufacturer to ensure proper fit and a long life span for your new pane. Use a wirebrush for removing any old paint or wood gunk from the frame's opening. Then sand the wood down to the bare wood in order to increase the seal.

When putting the new pane in place, use the tip of your putty knife to gently bed the new window against the frame of wood. Press glazier's tips into the frame every six inches. This will hold the new window securely in the frame.

Once the frame has been cured, coat the new joint with several coats of paint that match the rest of the frame. Allow the paint to dry completely before cleaning and maintaining your windows. Making sure your windows are clean and operating properly will extend their useful lifespan and increase the efficiency of your home's energy usage. You may want to replace your windows if they are damaged or are old. If you decide to go down this route, we suggest choosing a high-quality, insulated window that will reduce your utility bills. The type of window you choose will also affect the total cost of your project.
