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

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

Broken Glass

Cracked glass isn't just unsightly but can also let valuable sunlight and heat escape from your home. It's possible to fix a broken pane of glass without having to replace the entire window.

Start by putting on protective gloves and safety goggles. You can also use duct tape or painter's tape to make an "X" on the glass you plan to remove. This will stop any broken pieces from falling while you work, which could keep you from serious injuries.


Cover a small scratch on your window with tape to keep insects, water and wind out. If the crack is superficial just a single strip of tape will be enough. However should the weather be likely to get worse before you can replace the window, you might need a more durable plastic cover like an tarp or trash bag.

For cracks that aren't as deep, try using a strong adhesive designed specifically for windows, like Loctite Super Glue Glass. This high-tech glue is made to adhere to glass and dry clear to give a perfect finish. Apply it to the crack and let it dry completely before applying another layer.

Stress cracks are a different issue that can occur to your glass window. They are usually caused by large changes in temperature and can spread quickly across the entire glass window if it's not fixed. To stop stress cracks from occurring create an arc of a tiny size with glass cutters close to the crack. This prevents the crack from spreading and can slow it down by a day or so.

Examine the frame of the broken window to determine the size of the new pane. It should be slightly smaller than the opening to allow for expansion and contraction and to cover any imperfections in the frame or glass. After cutting your new glass, apply glaziers' compound around the edges of the frame and glass. Once the compound dries paint it over to match the rest of the frame.

Condensation inside of Double Glazed Windows

The appearance of condensation on the inside of double glazed windows usually indicates that the seal has been damaged somewhere in the window unit. This is a serious issue and could mean that heat is being lost from your home through the window.

Double glazing is designed to stop heat transfer between two panes, by sandwiching an air or vacuum layer between them. This creates a secure seal that blocks warm air from venting. But, if the glass is cold or colder than the frame, condensation will form on it, which can damage the window. If you've got condensation on your double-glazed window and you are unable to resolve it by opening the windows by using extractor fans, dehumidifiers or trickle venting then you may require the help of a professional.

It's rare for condensation to form on the outside of double glazed windows, but it could happen in the event that the seal between the glass and window frame has started to deteriorate. It is more common during winter, when the temperature is lower. This makes it easier for condensation to form. This is caused by an issue in the spacer between the frame and the window. This spacer contains desiccant, which is extremely absorbent and will absorb any excess moisture.

This can lead to moisture leaking into the gap when the desiccant has been saturated. This can cause condensation and water to build up in the gap, which is difficult to get rid of.

The majority of reputable window manufacturers provide a guarantee and will replace the unit and glass of the window if it is damaged 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 prevent further damage.

Shattering Window Glass

A window that is cracked isn't just an aesthetic issue, it can also present a security risk especially if the crack has been spreading. It is recommended to get it fixed as quickly as possible. You can use glass adhesives for windows in vehicles that you can buy on the internet or in many auto repair shops. Alternatively, you can make use of a glass compound designed for use in homes that can be found at a variety of hardware or home improvement stores.

Before you begin any work, put on thick cut-proof gloves and safety glasses. You can then sweep the area to remove large pieces of shards. Also, double glazing repairs should clean up any chips that fell. This will stop them from cutting you or a glazing repair technician later on.

It's a good idea climb a ladder instead of laying on the floor. This will enable you to reach all parts of the frame with ease and also protect your glass from falling. It's also a good idea to clean the rabbet before proceeding with the installation. This is the part of the frame around the window frame where the glass will go. Clean it off and then apply the linseed oil to the rabbet. This will help the new putty stick to the frame securely.

Once the frame is cleaned and the rabbet in place, it's time to get ready for the replacement of the damaged pane. Purchase a piece of double strength glass that is 1/8 inch smaller in both directions. You'll need to buy glass points which is a steel triangle that keeps the glass in the right place.

With the window sash taken off using a flat pry-bar to gently pry the sash away from the moulding of wood. You may have to scrape old glazing putty off with a utility blade or chisel. Then make use of the heat gun to warm up any putty that isn't able to come off. This will make it easier to peel off.

After the frame has been removed from the molding then gently press the new glass in its place. Then, with the help of a putty knife or glazier's point, fill in the gaps around it and smooth them out. After the putty has dried, paint the frame to match. Paint a little bit over the edge of the compound, then onto the glass to completely seal it.

Replacement Window Glass

If you're replacing a damaged window pane, you should first wear gloves and eye protection to shield yourself from glass shards. Tape the window's edges to prevent it from breaking again when you remove it.

Start by removing the old glazing compound and glazing points (small metal triangles) from the frame with a utility knife. Clean the entire frame opening and then apply a coat linseed to aid in adhering the new putty better.

When the frame is complete to be measured, you can measure it for an entirely new window and purchase it from a local home improvement store or another retailer. Make sure you order the pane one-sixth inch shorter in each direction than your measurement to allow for a snug fit.

It's not as difficult as you think to install the new window. However, it's crucial to follow the directions that are provided by the manufacturer in order to ensure a proper fit and a long-lasting replacement pane. Use a wirebrush to remove any paint or wood gunk from the frame opening. Then sand the wood to the wood's surface to increase the seal.

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

After the frame has cure, paint the new joint with several coats of paint to match the rest of the frame. Let the paint dry completely before moving on to cleaning and maintaining your window.
