Glazing Repair - How to Repair a Cracked Window

Glazing can have a significant impact on the energy efficiency of your house. This is especially true in older double-glazed windows.

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

Broken Glass

Glass that is cracked isn't just ugly but can also let valuable sunlight and heat escape your home. It's possible to fix damaged glass without replacing the entire window.

Put on safety goggles and gloves. Also, you should put a piece of tape in an "X" shape on the glass you plan to remove (duct or painter's tap works well). This will prevent any broken pieces from falling as you work, which can save you from serious injury.

If you've noticed a small crack in your window glass you can cover it with tape to keep out water, wind, and insects. One strip of tape is enough for superficial cracks however if you're concerned about the weather getting worse before you can replace your window, consider using an extra-strong plastic cover like a tarp, or a garbage bag, to hold the glass in place until you get a permanent fix.

Use a strong adhesive specifically designed for windows to repair cracks. Loctite Super Glue Glass is a great choice. This high-tech adhesive is formulated to bond to glass and then dries crystal clear for an ideal finish. Apply it to the crack, and let it dry completely before applying a new layer.

Stress cracks are a different issue that can occur to your glass window. They are usually caused by large temperature fluctuations, and can quickly spread across the entire glass window if they aren't fixed. To prevent stress cracks create an arc of a tiny size with glass cutters near the crack. This stops the crack from advancing, and can reduce the size by a few days.

If you're replacing an old window, measure the frame for the new pane. It should be slightly larger than the opening to allow for expansion and contraction and to make up for any imperfections on the frame or the glass. Once you've cut your new glass to size apply glaziers' compound around the edges of both the frame and the glass. Once the compound has dried, paint it to match the frame.

Double Glazed Windows Condensation Inside

The appearance of condensation on the inside of double glazed windows usually indicates that the seal has been damaged at some point along the window unit. This is a serious issue because it indicates that the heat that is coming from your home is being lost through the window and could be costly for you and your energy bills.

Double glazing is designed to stop heat transfer between two panes by putting an air or vacuum layer between them. This creates an airtight seal and keeps warm air from exiting the home. If the glass is warmer than the frame, condensation can form on the glass and cause damage to the window. If you notice condensation on your double-glazed window and you are unable to resolve it by opening the windows, by using extractor fans, dehumidifiers, or by trickle venting, you might require the help of an expert.

Condensation on the exterior of double-glazed windows is uncommon however it can happen if the seal has begun to break down between the glass and the window frame. This is more frequent in winter as the temperatures are lower and it's easier for condensation to form. The primary reason for this is a flaw in the spacer that is used between the frame and the window. The spacer is filled with desiccant which is very absorbent and will absorb any excess moisture.

This could result in water leaking through the gap after the desiccant has been saturated. This can lead to condensation and water leaking into the gap, and can be very difficult to get rid of.

Most reputable window companies provide a guarantee and will replace the unit and glass of the window if it's damaged due to condensation. It's essential to report any issues to your window installer when you notice them so that condensation can be fixed promptly to avoid further damage to the window unit and the frame around it.

Shattering Window Glass

A damaged window isn't just an aesthetic issue, it could also pose a security risk, especially if the crack is expanding. It is best to have it fixed as soon as possible. There are many methods to fix it, including using glass adhesives designed for vehicle windows that can be purchased online or at many auto repair shops. You can also use a glazing compound for home use that is readily available at many hardware and home improvement stores.

Before starting any task, put on thick gloves that are cut-proof and safety glasses. Then, sweep the area to get rid of large pieces of shards. You should also vacuum any chips. This will prevent them from causing injury to you or a glass repair technician later on.

It's a good idea climb a ladder instead of standing on the ground. This will allow you to reach all the areas of the frame and ensure that you are safe from falling glass. Before you begin it's important to clean the rabbet. This is the area where glass is placed. Apply a coat of linseed on the rabbet, then wipe it down. This will aid in helping the putty stick.

After the frame has been cleaned and the rabbet ready, it's time to plan the replacement of the broken pane. Purchase a piece of double strength glass that is 1/8 inch smaller in both directions. You'll need glass points which is a steel triangle that holds the glass in the right place.

With the window sash taken off and the pry-bar flat, use it to gently pull the sash off of the wood moulding. It is possible to scrape off old glazing with a utility knife or chisel. Then you can use the heating gun to warm any putty that doesn't come off. This will make it easier to remove.

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

Wear protective eyewear and gloves when replacing a damaged pane of glass. Tape the window's edge to stop it from breaking once you take it off.

Make use of a utility knife to remove the old glazing compound from the wood frame and glazing points (small triangles of metal). Clean the frame opening and apply a layer of linseed oil in order to help the new stick stick stick to it better.

Once the frame is ready, take measurements for the new window pane. Then purchase it from a local home improvement store or another retailer. Be sure to purchase the pane at least 1/6th inch smaller in each direction than your measurement to ensure an ideal fit.

Installing the new window is much easier than it sounds, but be sure to follow the directions of the manufacturer to ensure the right fit and 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 until it is the wood's surface to strengthen the seal.

Make use of the tip of the putty knife while installing the new window to bed it lightly against the wood frame. Then, press the glazier's points into the frame about every six inches to keep the new window firmly in the frame.

After the frame has cure, paint the new joint with several coats of paint to match the rest of the frame. Allow the paint to dry completely before cleaning and maintaining your windows. Maintaining windows in good condition and ensuring they function properly will increase their life expectancy and improve the energy efficiency of your home. If your windows are old or not in great shape then you might be better off with a full window replacement. If you decide to go this option, we suggest you choose a high-quality, insulated window that will lower the cost of your utility costs. The type of window you choose will also affect the overall cost of your project.
