Glazing Repair - How to Repair a Cracked Window

Glazing can have a significant effect on the efficiency of your home. This is particularly important for older double-glazed windows.

While it is possible to change the glazing points while the window is still in place, it's simpler and quicker if the glass and frame 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 sunlight and heat to escape your home. It's possible to fix the glass that is cracked without replacing the entire window.

Start by putting on protective gloves and safety goggles. You can also employ duct tape or a painter's tap to create an "X" on the glass you plan to remove. This will prevent any broken pieces from falling as you work, which could protect you from serious injury.

If you've got a tiny scratch in your window glass you can cover it with tape to block water, wind, and insects. If the crack is only superficial, a single strip of tape will suffice. However in the event that the weather is expected to worsen before you can replace the window, you may need a more durable plastic cover like a 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 choice. This high-tech glue is made to bond to glass and dries clear to give a perfect finish. Apply it to the crack and allow it completely dry before applying a new layer.

Glass windows can also develop stress cracks. Stress cracks are usually caused by drastic temperature changes and can spread rapidly across the entire window if not fixed. To stop stress cracks from occurring create an arc of a tiny size with glass cutters near the crack. This stops the crack from spreading, and can reduce the size by a day or two.

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

Condensation on the Inside of Double Glazed Windows

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

Double glazing is designed to prevent heat transfer between two panes by sandwiching an air or vacuum layer between them. This creates a airtight seal and keeps warm air from exiting the home. If the glass is cooler than the frame, condensation can form on the glass and cause damage to the window. If you are unable remove condensation from double-glazed windows by opening windows by using extractors, dehumidifiers, or trickle venting, you may need a professional.

Condensation on the outside of double-glazed windows is uncommon, but it can occur when the seal has begun to deteriorate between the glass and the frame. It is more common in winter, when temperature is lower. This makes it easier for condensation. This is caused by an issue with the spacer used between the frame and the window. The spacer is filled with desiccant which is very absorbent and will absorb any moisture that is present.

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

The good news is that most reputable window companies will offer an assurance on their products. They should replace the window unit and glass when it's damaged by condensation. It is essential to report any problems to your window installer immediately you notice them, so that the condensation can be repaired as soon as possible to prevent further damage to the window unit and the frame around it.

Shattering Window Glass

A damaged window isn't just a cosmetic issue, it can also present a security risk especially if the crack is growing. It is best to get it repaired as quickly as you can.

Alternately, you can make use of a glass compound designed for use at home that can be found in a lot of hardware and home improvement stores.

Put on your gloves with a thick layer of protection and safety glasses before you start any task. Clean the area thoroughly to get rid of any large shards. Also, you should vacuum up any chips. This will prevent them from cutting you or a glass repair worker later on.

It is better to climb a ladder rather than on the ground. This will allow you to reach all the areas of the frame, and will keep you safe from falling glass. It's also a good idea to clean the rabbet prior to starting with the installation. This is the area around the perimeter of the window frame, where glass will be. Apply a coat of linseed to the rabbet and wipe it clean. This will aid in helping the putty stick.

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

With the window replacement sash off the way, carefully pry it away from the wood molding using an angled pry bar. You may have scrape off old glazing with a utility knife or chisel. Then make use of the heat gun to warm up any putty that doesn't be removed. This will make it easier to peel off.

After the frame is removed from the molding then gently press the glass back into its place. Then, with a putty knife or glazier's point, fill the gaps around it and smooth the edges. 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.

Once the frame is in place and you are ready to measure it for the new window pane. Then purchase it from a home improvement store or other retailer. Make sure you order the pane 1/6th inch shorter in each direction than your measurement to allow for a snug fit.

Installing the new window is much easier than you think, however make sure you follow the directions of the manufacturer to ensure correct fit and a long life span for your new pane. Use a wire brush to clean the frame of old paint or wood gunk. then sand it to bare wood in order to improve the seal between the sash and frame.

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

Once the frame has been cured, coat the joint with a few coats of paint that match the rest of the frame. Let the paint dry completely before you begin cleaning and maintaining your window.
