Do-It-Yourself Double Glazing Repairs
Double glazing keeps a building toasty but can develop problems in time. Problems like leaking glass, broken glass or foggy windows could cause a loss of energy efficiency, expensive repairs, and potential health problems.
FENSA certified installers are able to help you maintain or repair your double glazing in order to be energy efficient and meet the requirements of legal compliance and resale values.
Broken Panes
A window that is damaged can be a major problem, blocking light, air and possibly even pests from getting into your home. While you could certainly hire a professional to replace the damaged window, it's also possible to fix the problem yourself for only a fraction of the cost.
You'll have to remove the old window. To protect yourself from lead and glass dust shards, wear protective glasses, gloves and a mask. Install a sturdy surface in an area that is well ventilated. It is also recommended to place a drop cloth under the work area to catch loose glass that is being removed. It is recommended to have an HEPA vacuum in the vicinity to clean up dust, debris, and hazardous waste as you work.
Use a utility blade to scrape the old glazing putty off once the old window was removed. Be careful not to damage the wooden frame of the window. If the old putty is particularly stubborn, you can try using a heat gun to soften it prior to scraping it away with a knife. Wear safety glasses and be careful to avoid getting hot glass or wood pieces in your eyes when using a heating gun.
The next step is to prepare the frame for the new pane. To account for wood expansion and contraction take the opening measurement and subtract one sixteenth inch in both directions. Then, have the local hardware store cut a piece of double-strength plastic that fits the opening precisely. Dry-fit the new glass to ensure it fits snugly before putting it in.
Once you have the new glass in place, lay a small bead of caulk made from latex around the edge of the opening to provide a good weather seal. The glazing points are then placed to secure the new glass. For standard window glass sizes, you will only need to install two points per edge.
After the new glazing compound dries, you can paint it to match the rest. If you're worried about the potential for cracks, you can apply a heavy-duty strip of masking tape to keep superficial cracks from getting worse.
Frames that are damaged
The first thing you need to do is look over the frame. You will need to have it repaired professionally if there are cracks or corrosion or rust, or if the frame appears to be broken into two pieces. Metal frames can't be glued together, and attempting to weld or solder them yourself can cause permanent damage.
If the frame has not been severely damaged It can be cleaned with a tiny brush, some conservation detergent and water. This will eliminate any grease, dust or dirt that has built up over the years. A careful cleaning of old frames with ornate carving or gesso will often reveal the original shine beneath the layers of dust.
If the frame has been damaged it will require needle-nose pliers with a flat surface wood putty, sandpaper and a small clamp. Remove the back as well as the photo and glass of the frame. The frame should be removed at the corners, where you can see the nails or brads. If possible, open the joints and scrape away any glue that is old and apply fresh glue.
Loose Compound
The glazing compound that is used to hold glass window panes in their wooden frames is a vital part of any historic building's energy efficiency. It seals wood, bonds glass to frame and sheds water to protect it from water over time. Cracks or gaps in this compound cause air infiltration, which decreases insulation and raises the cost of utility. Maintaining a schedule for repairs on double-glazed windows can help keep them running 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. This seal can reduce the cost of energy and improve the comfort of your home. If you hear loud sounds from outside, such as traffic and machinery It could also mean that the glazing tape is worn out or is missing.
Remove the old tape and clean the frame edge thoroughly. Apply a new piece 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 double-glazed windows.
Standard super glues are excellent for metal, wood, and other common materials. However they're not the best choice for glass surfaces. Choose a glass-based adhesive such as Loctite Extreme Glue Gel. This kind of adhesive is made to withstand moisture and UV light, making it a good alternative for repairing double-glazed windows.
You'll need to apply a degreaser on the exterior of your window frame and sash before you begin to repair it. This will ensure that the new adhesive sticks properly. Prepare Glazier and Glazing that will be glazed with an oil-based primer. Prime the entire surface, including the back of sash, where it rests within the frame.
It is possible to repair most double-glazed window problems however, if the windows are severely damaged, or if they no longer provide adequate insulation, replacement may be the best option. Consult an experienced handyman or glazier to help you make the best decision. Regularly checking and fixing your windows will ensure they look their best and function smoothly for many years to come.
Foggy Panes
Foggy windows occur when the window seal breaks and allows air to get between glass panes and gradually build in moisture. Foggy windows can trigger various problems, from condensation and calcium deposits to black staining and fungus. It's not just unsightly but also causes lower energy efficiency and higher heating or cooling costs. Fortunately, the problem is fixable. Foggy windows are usually caused by a simple moisture buildup, so the first step is to remove as much of the moisture as you can. You can accomplish this by using a defogging solution or shaving cream. If none of these solutions work then it's time to call in an expert.
Double pane windows are able work because of the space between them. This space is filled with the gas argon or krypton. These non-toxic gases are more dense than air and have a slower heat transfer. If the gas has leaked out the windows, they aren't being adequately insulated. The replacement of your windows with new IGUs will not only fix the fogging issue, but will also boost your home's energy efficiency too.
Some homeowners believe that they need to replace the entire window when the fogging happens, but this isn't the case in all cases. Some glass shops offer to replace the insulation unit (IGU) only, and without replacing the entire frame or the sash. This is a cheaper option that's just as effective at fixing your windows.
Although there are DIY ways to stop window condensation, like shaving gel or defogging lotion it is best to call an expert to ensure that the task is done safely and in a correct manner. A window repair professional will first make holes in the glass and then inject a cleaning solution between the panes. The window repair specialist will scrub the surface and dry the inside, restoring the appearance and function of the window.
