Do-It-Yourself Double Glazing Repairs
Double glazing can help keep the temperature of a home warm, but it could also cause problems over time. Issues like leaks glass, broken glass or foggy windows could result in a decrease in energy efficiency, expensive repairs, and health problems.
FENSA certified installers can help you repair and maintain your double glazing to ensure that it meets energy efficiency requirements to ensure compliance with the law and potential resale value.
Broken Panes
A damaged window can cause a lot of issues, since it could block light, air, and even pests. While you can certainly employ a professional to fix the broken pane, it's also possible to fix the problem yourself for a fraction of the cost.
You'll have to remove the old window. Begin by putting on protective glasses, work gloves and a dust mask to protect yourself from lead shards and glass dust. Install a sturdy work surface in a well-ventilated area. Place a dropcloth under the work surface to catch any glass that falls when you take it off. Keep a HEPA vacuum in your vicinity to clean up dust, debris, and hazardous waste when you work.
Once Glazier and Glazing Services is removed, use a utility knife to scrape away the old glazing putty. Be careful not to damage the wooden frame of the window. If the old putty is having a particularly hard time getting off, you can use a heat gun first to soften it. Wear safety goggles and be careful to avoid getting hot wood or glass fragments in your eye when using a heatgun.
Then, you can make the frame ready to receive the new pane. Take measurements of the opening and subtract 1/16 inch in both directions to take into account the expansion and contraction of the wood. The hardware store in your area can then cut the double strength glass to precisely fit the opening. Dry-fit the glass to ensure it fits perfectly before installing.
After you have installed the new glass, apply a small amount of latex caulk to the perimeter of the opening for a weather seal. Install the glazing points next to secure the new glass. Typically, you will need two points along each edge for windows of standard sizes.
After the new glazing compound dries you can then paint it to match the rest. If you are concerned about cracks then you can use masking tape that is heavy-duty to stop cracks on the surface from becoming worse.
Frames that are damaged
The first thing you need to do is examine the frame. You will need to have it repaired professionally if there are cracks or corrosion or rust, or if the frame is broken into two pieces. Metal frames aren't able to be glued together, and attempting to weld or solder them yourself can cause permanent damage.
If the frame hasn't been damaged too badly, you can clean it with a small brush, some conservation detergent and water. This will get rid of any dirt, grease, or dust that has built up through the years. Careful cleaning of antique frames with ornate carving or gesso will often reveal the gleaming original finish underneath the layers of dust.
If the frame is damaged, you'll need a pair of needle-nosed pliers, wood putty and sandpaper as well as a small clamp. Start by taking off the glass, photo and the back of the frame. Take care to remove the frame at the corners where there are brads or nails. If possible, you can open the joints and scrape away any glue that has been used and apply new glue.
Loose Compound
The glazing compound that is used to hold glass window panes in their wooden frames is a vital element of any building's energy efficiency. It seals wood, bonds glass to frame, and sheds water to protect it caused by water over time. Cracks or gaps in this compound cause air infiltration, which decreases insulation and raises the cost of utility. Be sure to keep up with the maintenance work of your double-glazed window to ensure that they run smoothly.
The weatherstripping may be worn out or loose if you see drafts in the window frames. Replacing this seal will reduce the energy costs and improves the comfort of your home. If you hear loud sounds from outside, such as traffic and machinery, it could also indicate that the glazing tape is worn or is missing.
Remove old tape from the edge of the frame and scrub the area thoroughly. Apply a new strip of tape to the edge of the frame and press it firmly. You can purchase this at any hardware store, and it's a low-cost option to boost the performance of your double-glazed windows.
While the standard super glues work well for bonding wood, metal and other commonly used materials, they're not suitable for glass-based surfaces. Choose a glass-based glue, such as Loctite Extreme Glue Gel. This type of adhesive is designed to withstand moisture and UV light which makes it a great option for repairing double glazed windows.
Before you begin to repair your windows, it is best to clean the the frame and sash using a degreaser to ensure that the new glue adheres properly. Then prepare the area that will be coated by priming it with an oil-based primer. Make sure to prime the entire area, including the back of the sash where it rests within the frame.
While you can repair a lot of issues with your double-glazed windows, if they are severely damaged or don't offer sufficient insulation, replacement may be the best choice. Talk to a glazier who is experienced or handyperson to make the best decision. Regular inspection and maintenance of your windows will ensure they look their best and run smoothly for many years to come.
Foggy Panes
Foggy windows occur when the window seal fails and allows air to get between glass panes, and then slowly build up moisture. Foggy windows can trigger a variety of problems, ranging from calcium deposits and condensation to black staining or fungus. It's not just ugly but also leads to a reduction in energy efficiency as well as increased heating or cooling costs. However, it is possible to correct the issue. Foggy windows are typically caused by simple moisture buildup, so the initial step is to get rid of as much moisture as possible. This can be accomplished by using a defogging solution or shaving cream. If these measures don't work then it's time to call in an expert.
The reason double pane windows work is because they have a space between them. This space is usually filled with argon or krypton, which are non-toxic gases that are more dense than air, and can hinder heat transfer even more. If the gas has escaped and is escaping, it indicates that your windows aren't well-insulated as they should be. Replace your windows with IGUs to eliminate the fogging and increase your home's efficiency.
Many homeowners are under the impression that they need to replace their whole window if it becomes foggy, but this isn't always the case. In fact some glass shops provide replacement of just the IGU, or insulating glass unit (IGU) without replacing the entire sash or frame. This is a more affordable option and could be equally effective in fixing your windows.
While there are a few DIY remedies to prevent window condensation, like shaving gel or defogging cream, it's best to call an expert to ensure that the job is done properly and safely. A window repair expert will first drill holes into the glass, and then inject cleaning solution between the panes. They then clean the surface that has been soiled and dry the interior of the window, restoring its appearance and function.
