Four Common Signs That Double Glazed Window Repair Is Necessary
Double glazing windows are a fantastic option to save energy. However, they can be damaged as time passes. Fortunately, they are easy to repair.
A leaky seal can be identified by foggy glass, condensation in between the panes, and even mist. A professional can usually resolve this issue without needing to replace the entire window.
Broken Panes
A rock thrown or even a fierce breeze can break the double-pane windows. And, when this happens, it could be difficult to know if the whole window must be repaired or if a replacement could be salvaged from the insulation benefits this type of glass is renowned for.
It is good to know that repairing a damaged glass pane in a double-glazed window isn't as difficult as it might seem. If you have the proper tools and know how to use it you can repair it yourself. Making use of the right tools will ensure that you're not adding any additional damage to the windows you already have. You will also be able to avoid any injuries due to working with sharp glass.
The first step is removing the old sealant from the broken glass. You can do this by hand so long as you've got gloves that are protected and a way to dispose of the waste close at hand. Use a multipurpose tool or deglazing knife to do the job. Once you've removed the sealant from the window, carefully remove the broken glass and store it in a safe place.
Next, you need to prepare the frame to accommodate the replacement pane. Use a utility knife to scrape away any old caulking and paint from the rabbets (the grooves in the sash where the glass sits). Then, you can use a paint stripper or sandpaper, to expose the naked wood. Apply a coat of exterior primer to the surface that is exposed.
You can then apply putty on the rabbets in preparation for the installation of the glass. The putty should be warm and malleable, so that it can be applied to the rabbets. It is crucial to evenly press down on the entire surface, ensuring that there are no gaps.
Once the putty has been set, you can install the wooden stops, and then seal the edges to ensure the double pane windows are as solid as you can. Replace the weather stripping on the bottom of the frames to increase airflow and stop water from entering your home. This will also help lower the cost of energy.
Foggy Glass
Often, foggy windows can be a sign that seals have failed and draughts and moisture could get into the gap. This is more common in humid and wet regions where wooden frames could be damaged if exposed to excessive amounts of condensation and water. If this is the case, a new window may be needed but it's generally more cost-effective to address the issue using the existing glass unit.
To ensure that the glass is not broken by drilling small holes into the frame with a carbide-tipped bit. You can then apply a dehumidifier or a cleaning solution to get rid of the accumulated moisture between the two glass panes. It is important not to do this during a time that is extreme cold or hot. This will put too much strain on the glass, and could cause it to shatter. It's also a good idea to wear gloves and safety goggles since you'll be working with extremely sharp tools close to the glass.
Once the fog has been cleared and the glass is clean, you can put a small tube into one of the holes. You can apply a spray rinse solution to wash down the glass panes and clean off any remaining debris. Once the window is dry, you can apply a caulk around both the hole and the edge of the glass to protect it from the elements.
Depending on how well you're skilled at DIY, you may be tempted to repair the leaky seals yourself, rather than call in a professional. This is a risky job, and you'll need to monitor the condition of any plugs inserted into the gap. Even if you succeed however, it is likely that the issue will recur in six months or so when new moisture is absorbed into the gap. This could lead to condensation and draughts within the home upvc window lock repair as also posing as an electrical risk. This is why it's normally best to employ a licensed tradesperson to do the work.
Condensation between the Panes
Condensation on double-paned windows is more than an issue. It is a sign that the seals are failing. This allows moist air to move in which could cause damage to the gaskets, and when the condensation is very severe, can also jam or cause rot to wooden window frames. This is most commonly repaired by replacing the window with a new one that has gaskets and sealings.
However, the cost of doing this can be high and it's not always possible, especially in the event that one or both the panes have cracked or shattered. There are, however, alternatives to replacing the entire glass unit that can offer long-term double repair solutions for the glazing.
First, try to clear any condensation with commercial defogging products such as WD-40 Original For Windows. This spray can be spray on both sides of the glass, and will absorb all moisture within minutes. This is best done at least every day, but is able to be repeated if required.
If the problem persists, it may be necessary for you to drill two small holes just below the lower edge of the window. When the sun shines on the outer glass, it will heat up and if there's any condensation in the window this will flow towards the holes and be vented out through the holes as the air expands. This usually clears the window of condensation, however, since it hasn't addressed the root of the problem in the beginning it is likely to remain a problem for a long time.
Alternatively, it is possible to employ a hole-free approach but this will not perform as well and could run the risk of cracking or shattering the glass. A special adhesive is applied to the cracks to stop them from spreading further and this can be a viable long-term solution but it's not as efficient as a replacement unit equipped with complete sealing. It is recommended to hire a professional in both cases to ensure that the procedure is properly followed and to avoid any future issues with leaks or condensation.
Mist
When a layer of mist appears on windows, it is usually a sign that the seal of the window has failed. In certain cases it is possible to repair the issue. However, in the majority cases it will require replacing the seal.
This problem can occur in both new and old double-glazed windows. It is typically caused by an extreme temperature difference between the indoors and outdoor. When cold air is pushed against the warm air, condensation may form inside the window. The condensation then sets on the surface of the glass making fog or mist.
The way in which this is prevented with modern double glazing is that the space between the panes is filled with a gas known as argon. The gas acts as a barrier between cold and warm air. The area is also sprayed with a silica formula that is designed to absorb moisture between the glass panes. These chemicals can wear out over time and you could see moisture build up in the window.
If the condensation is confined on the inside of your double-glazed windows, it could be possible to repair them rather than replacing them. The repair process will involve removing the sealed unit from the frame, tearing the panes apart from the spacer bars, and then cleaning each one thoroughly, and then replacing the desiccant. The final result is a window that is clear and free of condensation. This is a great option for those trying to save money, but don't want to replace their windows.
If your glass is broken or extensive rot, or an unsound frame It is evident that replacement is required. If you do have issues with the window seal then it may be possible to save your windows and make them more energy efficient again.
