Four Common Signs That Double Glazed Window Repair Is Necessary
Double glazing windows are an excellent option for saving energy. However, they could be damaged over time. Fortunately, they are simple to fix.
Foggy glass, condensation between the panes and mist are all indications of an issue with the seal. The good part is that a professional can typically solve this issue without having to replace the entire window.
Broken Panes
A stray baseball, rocks thrown at the ground, or even the force of a strong wind can crack the double pane of a window. When this happens, it is difficult to determine if the whole window should be replaced or the insulation benefits of this type glass can be salvaged with a simple repair.

Make use of a multi-purpose tool or deglazing knife to do the job. Once you have removed the sealant, carefully lift the damaged pane and put it in a safe place to store it for a while.
The next step is to prepare the frame for the replacement pane. Make use of a utility knife scrape away any old caulking and paint on the rabbets (the grooves in the sash that the glass rests). You can then apply a paint stripper or sandpaper, to expose the exposed wood. Apply an exterior primer to the exposed area.
You can then apply putty on the rabbets in preparation for the installation of the glass. The putty needs to be soft and warm so that it can be used in the rabbets. It is crucial to press down evenly on the entire surface, ensuring that there aren't any gaps.
After the putty has set, you can reinstall the wooden stops and silicone the edges to ensure that double pane windows are as secure as you can. Replace the weather stripping at the bottom of the frames to improve airflow and prevent water from getting into your home. This can also reduce the cost of energy.
Foggy Glass
Most of the time, foggy windows are a sign that seals have failed and that moisture and draughts enter the window. Most prevalent in humid and moist climates where wooden frames could rot when exposed to excessive moisture and condensation. In this instance you may have to replace the window, but it's usually cheaper if the glass unit can be repaired.
This can be accomplished by drilling small holes into the inside of the frame with a carbide-tipped drill bit to avoid breaking the glass panes. The moisture that is trapped can be removed using the aid of a dehumidifier or cleaning agent. It's important to avoid doing this during a time that is extremely cold or hot. This can put too much pressure on the glass, and could cause it to break. Wear safety gloves and goggles because you'll be working with sharp tools near the glass.

Depending on how well you're adept in DIY, you may want to try to repair the leaky seals yourself rather than calling a professional. But, this is an extremely risky undertaking and you'll need to check the condition of the plug as it is inserted into the gap. Even if the issue is solved but it's likely to come back within a period of six months since moisture will continue to creep into the gap. This can cause condensation and draughts in the home, as also posing as an electrical hazard. This is the reason it's recommended to hire a certified tradesperson to carry out the work.
Condensation Between the Panes
Condensation on double paned windows is more than just an inconvenience. It indicates that the seals are not working. This allows moisture to move in, which can cause damage to the gaskets, and when the condensation is extreme it can cause jams or rot wooden window frames. This is typically fixed by replacing the window with new ones that have gaskets and seals.
This can be expensive and not always feasible. Particularly when either or both of the panes is cracked or shattered. There are, however, alternatives to replacing the entire glass unit to offer long-term double glass repair solutions.
First, try to eliminate any condensation using a commercial defogging product such as WD-40 Original For Windows. This spray can be applied on both sides of glass and will absorb moisture in a matter of minutes. This is best done at least every day, but can be repeated if necessary.
If the issue continues to persist the issue is not resolved, it might be necessary double glazing repair near me to drill two small holes just below the bottom edge of the window. When the sun shines on the outside glass, it will heat up, and if there's any condensation in the window, it will be pushed towards the holes, and then 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 initial place it is likely to remain a problem for a long time.
It is also possible to use an alternative that does not require holes, but it isn't as effective and could crack or shatter the glass. A special adhesive is inserted into the cracks to stop them expanding further. This can be a viable long-term solution, however it's not as efficient as a replacement unit with complete sealing. In both instances it is best to have the job completed by a professional to ensure that the process is followed properly and to avoid problems of future leaks or condensation.
Mist
If a mist appears on a window it is usually a sign that the window seal has failed. In some cases this can be fixed, but in most it will require replacement of the unit.
This problem can happen in both new and old double-glazed windows. It is typically caused by an extreme temperature difference between the indoors and outdoors. When cold air is pushed against the warm air, moisture may form within the window. The condensation then sets on the surface of the glass and forms a fog or mist.
Modern double glazing works by filling the gap between the glass panes with the gas argon. This serves as a barrier between the cold and warm air. The space is also sprayed with an exclusive silica formula that has been designed to wick away moisture between the glass panes. These chemicals can wear out over time and you could notice a buildup of moisture inside the window.
If the condensation is only on the inside of your double glazed windows then it may be possible to repair them rather than replacing them. The repair will involve taking your sealed unit out of the frame. Separating the panes from the spacer bars and then cleaning them thoroughly. The result should be an uncluttered window and free of condensation. This is a great choice for those looking to save money, but don't want to replace existing windows.
