FENSA certified installers can help you repair and maintain your double-glazed windows to meet the energy efficiency requirements for legal compliance and resale value.
Broken Panes
A broken window could be a major issue, blocking light, air and possibly even pests from entering your home. You can get an expert to fix the damaged window, however, you can do it yourself at a fraction of the cost an expert would charge.
You'll need to take out the old window. Begin by putting on protective glasses, work gloves and dust masks to protect yourself from glass shards and lead dust. Set up a level surface that is well ventilated. Place a dropcloth under the work surface to catch any glass that falls when you take it off. It is recommended to have a HEPA vacuum close by to clean up dust, debris and hazardous waste when you work.
After the window has been removed using a utility knife, you can use it to scrape the old glazing putty. Be careful not to damage the wooden frame of the window. If the old putty is having an especially difficult time getting off, you can use a heat gun to soften it. Be sure to wear safety glasses when working with a heat gun, and be cautious to avoid getting hot wood shards or glass fragments in your eyes.
The next step is to prepare the frame to accommodate the new pane. To account for wood expansion and contraction, measure the opening and subtract one-sixteenth of an inch in both directions. Your local hardware store will cut an inch of double strength glass to fit the opening exactly. Before installing the new glass dry-fit it to ensure an ideal fit.
Once you have the new glass in place, lay a tiny amount of latex caulk around the edges of the opening to create a weather-proof seal. Then, install the glazing points to hold the new pane in the right place. For standard sizes of window glass, you will only need to install two points per edge.
Once the new coating is dry it is possible to paint over it to match the frame. If you are concerned about the possibility of cracks, you can use a strong masking tape to prevent cracks that appear superficial from getting worse.
Frames that are damaged
You should examine the frame first. If there are cracks, rust or corrosion or the frame is broken into two separate pieces you will need to take it to a professional repair. Metal frames can't be glued together and attempting to solder or weld them by yourself will cause permanent damage.
If the frame has not been severely damaged, you can clean it with a tiny brush, some conservation detergent and water. This will eliminate any grease, dirt or dust that has built up through the years. Cleaning old frames with intricate carvings or gesso could reveal the original finish beneath the dust.
If the frame is damaged, you will require a pair of needle-nosed pliers and sandpaper, aswell with a small clamp. Begin by removing the glass, photo and back of the frame. The frame should be removed at the corners, where you can see nails or brads. If possible, you can open the joints and scrape away any glue that is old and apply fresh glue.
Loose Compound
The glazing compound that holds the glass panes in their wooden frames is a crucial component of the energy efficiency of any building. It is a sealant for the wood, it binds the glass to the frame and sheds moisture to prevent water damage as time passes. The material can break or have gaps that allow air to get in, lowering insulation values and causing higher utility bills. Maintaining a schedule for repairs on your double-glazed windows will help keep them operating smoothly and efficiently.
If you notice that there are drafts around the edges of your window frames, the weatherstripping seal may be worn out or loose. Replacing the seal can reduce energy bills and improves comfort. If you hear loud sounds from outside, such as machinery and traffic it could be a sign that the glazing tape is worn or missing.
Remove old tape from the edge of the frame and clean the area thoroughly. Apply a new piece tape to the edge of the frame and press it firmly. It's available at any hardware store and it's a low-cost option to boost the performance of double-glazed windows.
While standard super glues are great to bond metal, wood and other common materials, they're not suitable for use on glass-based surfaces. Choose a glass-based adhesive such as Loctite Extreme Glue Gel. This type of adhesive is made to resist moisture and UV light making it a great option for repairing double glazed windows.
Before you start repairing your windows, it is best to clean the surface of the frame and sash with a degreaser to ensure the new glue adheres properly. Then prepare the area to be painted by applying an oil-based primer. Be sure to prime the entire area including the back of the sash where it rests in the frame.
While you can fix many issues with your double-glazed windows, if they're severely damaged or no longer offer sufficient insulation, replacement might be the best option. Get a professional glazier or handyperson to make the best decision. Regularly checking and fixing your windows will ensure they look their best and function smoothly for years to come.
Foggy Panes
Foggy windows are caused when the window seal is damaged. This allows air to penetrate and slowly build up moisture between the glass panes. Foggy windows can cause many issues, ranging from condensation and calcium deposits to black stains and fungus. In addition to looking ugly, it also causes reduced energy efficiency and higher heating or cooling costs. Fortunately, the problem can be resolved. Foggy windows are often caused by the simple accumulation of moisture, so the first step is remove as much moisture as possible. This can be accomplished by using a defogging agent or shaving cream. If these solutions are not working, it is time to contact a professional.
The reason double pane windows work is due to the space between them. The space is filled with the gas argon or krypton. These non-toxic gases are denser than air and can slow heat transfer. If the gas has escaped and is escaping, it indicates that your windows aren't properly insulated as they should be. Replacing your windows with new IGUs will not only eliminate the fogging, but also improve your home's energy efficiency as well.
Some homeowners believe they must replace the entire window if the fogging happens, but it's not always the case. In fact, some glass shops will offer to replace just the insulating glass unit (IGU) without replacing the entire sash or frame. This is a cheaper solution and could be equally effective in fixing your windows.
Although there are some DIY solutions to avoid window condensation, like shaving gel or defogging lotion, it's best to call an expert to ensure the job is done properly and safely. A window repair professional will make holes in the glass and then inject a cleaning solution into the space between the panes.
