Four Common Signs That Double Glazed Window Repair Is Necessary
Double-glazing windows are an excellent option to reduce energy consumption. However, they could be damaged as time passes. Fortunately, they are simple to repair.
Foggy glass, condensation between the panes and mist are signs of an issue with the seal. The good news is that a professional will usually solve this issue without replacing the entire window.
Broken Panes
A stray baseball, rocks thrown at the ground, or even the force of a strong wind can cause a crack in windows with double panes. When this happens, it can be difficult to determine if the whole window has to be replaced or whether the insulation benefits of this type of glass can be restored with an easy repair.
Repairing a damaged glass pane of a double-glazed window isn't as complicated as it might seem. If you have the proper tools and know how to use it you can fix it yourself. Making window glazier of the right tools will ensure that you are not adding any additional damage to the windows you already have. You will also be able to avoid any injuries from working with sharp glass.
The first step is removing the old sealant from around the broken glass. You can do this by hand as long as you have gloves to protect yourself and a method to dispose of the waste close to hand. Make use of a multi-purpose tool, or a deglazing knife to complete the job. After you have removed the sealant, carefully lift the damaged pane and put it in a safe location to store it for a while.
Next, you need to prepare the frame to accommodate the replacement pane. Use a utility knife to scrape away any old caulking and paint on the rabbets (the grooves in the sash that the glass rests). The wood that is bare can be exposed using a paint remover or sandpaper. Apply an exterior primer to the exposed area.
When the rabbets are ready, you can apply putty to them in preparation for reinstalling the glass pane. The putty must be soft and warm enough that it can be pressed in the rabbets. It is crucial to evenly press across the entire surface to ensure that there aren't any gaps.
After the putty is been set, you can install wooden stops and silicone around the edges of your double pane window to ensure it is as tight as you can. Replace the weather stripping that is at the bottom of the frames in order to improve airflow and prevent water from entering your home. This can also reduce your energy bills.
Foggy Glass
Foggy windows can be an indication of a damaged seal, allowing drafts or moisture to get into the gap. This is most common in humid and wet environments where wooden frames can rot if exposed to too much water and condensation. In this situation you may have to replace the window, but it's usually cheaper if the glass unit can be repaired.
To ensure that the glass is not broken by drilling small holes into the frame using a carbide-tipped drill. The moisture trapped inside can be removed with the aid of a dehumidifier or cleaning agent. When you're trying to do this, it's important not to choose a time that the sun is extremely hot or extremely cold. This can put too much stress on the glass and may cause it to break. Wear safety glasses and gloves because you'll be working with sharp tools near the glass.
After the fog has been cleared out after which you can add a small tube to one of the holes. You can apply a spray rinse solution to wash the panes of glass and remove any remaining debris. After the window has dried, you can use caulk to close the hole and seal the glass edge.
You may be able repair the leaky seals yourself if you are a DIY expert. This could be a risky task, and you'll have to be aware of the condition of any plugs that are placed into the gap. Even if the problem is resolved, it's likely to return within six months as moisture will creep back into the gap. This can cause draughts, electrical hazards and condensation within the home. It's best to hire a certified professional to complete the task.
Condensation Between the Panes
Condensation in double pane windows is not just a nuisance it's a sign that the seals between the glass are breaking down. This allows moisture to move in, which can harm the gaskets and, when the condensation is very severe it can cause jams or rot wooden window frames. The most common method to address this issue is to have the window replaced with a new one that has proper gaskets and seals.
However, the expense of doing this can be high and it is not always feasible, especially if one or both of the panes have cracked or shattered. There are, however alternatives to replacing the entire glass unit that can provide long term double repair solutions for the glazing.
The first step is to try to clear the condensation by using a commercial defogging spray such as WD-40 Original for Windows. This spray can be sprayed on both sides of the glass, and will absorb all moisture within minutes. This is best done at least once a day, but can be repeated if necessary.
If the issue persists, it may be necessary to make a couple of small holes on the outside of the window, just below the bottom edge. The sun will warm the outer glass and any condensation that forms in the window will move towards the holes. As the air expands, it will vent out of the holes. This is usually enough to clear the window of condensation, however, since it hasn't solved the issue in the first place it could remain a problem for a long time.
Alternatively, it is possible to use a hole-free method however this won't work as well and runs the possibility of breaking or shattering the glass. This is a long-term fix that involves placing a specific glue into the cracks. It is a viable option but it's not as efficient as a replacement with an entire seal. It is best to hire an expert to ensure the process is correctly followed and to avoid any future issues caused by leaks or condensation.
Mist
When a layer of mist appears on windows, it is generally an indication that the window seal has failed. In some instances, this can be repaired but in most it will require replacement of the unit.
This problem can occur with both new and old double-glazed windows. It is typically caused by an extreme temperature difference between indoors and outdoors. This can cause moisture to build up inside the glass as the cold air comes in contact with warm air. The condensation then dry on the glass's surface and forms a fog or mist.
The way that this is avoided with modern double glazing is that the space between the panes is filled with a gas named argon. This acts as an effective barrier between warm and cold air. The area is also sprayed with using a silica-based formula that is that absorbs moisture between the glass panes. It is not uncommon for these chemicals to wear out in time, and this is when you'll start to see the accumulation of moisture in the windows.
If the condensation is only visible on the inside of the double-glazed windows, it may be possible to have them repaired instead of replaced. The repair involves removing your sealed unit from the frame. The panes will be separated from the spacer bars, and cleaning them thoroughly. The final result will be windows that are clear and free of condensation. This is a great choice for those who want to save money but don't want replace their windows.
If you have glass that has broken or extensive rot, as well as an unsound frame It is evident that replacement will be required. If you're having issues with the window seal, it may be possible for your windows to be saved and made more energy efficient. You can reach out to an individual company in your area that is specialized in double-glazed window repairs and learn about the alternatives you have to fix the current glass.
