How to Repair a Double Glazing Window
Double glazing repairs are often best left to experts as very specific tools are required. Professional repairs come with a warranty that you will not get if you try it yourself.
Common problems include broken handles or locks that don't open easily, discoloured UPVC frames and misting between glass panes. It's time to call a double glazing technician if you notice any of these problems.
Broken Glass
If a window cracks, it is important to repair it as soon as possible. This will stop the crack from spreading into the form of a spider's web, and will keep cold, water and debris from the home. In many cases, homeowners may be able to fix the cracks themselves without having to replace the entire window pane.
To begin, the cracked glass must be removed from the frame. This can be done by hand with a putty knife or another deglazing tool. When dealing with broken glass, it is recommended to wear gloves and eye protection. After the glass has been removed and disposed of, it should be put in a safe interim storage area and then properly disposed.
After removing the old sealant, and the glazing points, the frame should be thoroughly cleaned using wire bristles and a damp cloth. It is then a good idea to employ a hair dryer or a heat gun to soften the remaining sealant and glazing and make it easier to take off. After cleaning the frame it is advisable to apply a small amount of linseed to the rabbets on which the glass will be placed to ensure that the glass sticks tightly.
Next cut the glass to the right size to ensure that it fits in the frame. If the gap is large, a piece of glass repair film can be used to fill in the gap and help hold the glass in position. If the gap is much smaller, a piece clear or concealing tape may be placed on both sides of the crack in order to stop it from growing further.
Once the glass is cut to size, it can be inserted into the empty frame and fixed by using putty or glazing. It is then a good idea to apply any paint that may be needed on the frame. If the glass has a wood frame around it, you should remove the pieces prior to installing the new glass. They could be damaged in the removal of the old window and replacing it.
Condensation
Double glazing can cause condensation. If condensation does occur it is recommended to air-condition the room as frequently as you can, particularly in times of high humidity. This will help to reduce condensation. A dehumidifier is also useful. If you are unable to stop the condensation, seek out a professional as quickly as you can to repair your windows.

One method of removing condensation from your double-glazed windows is to use a non-abrasive product such as iron oxide or cerium oxide, which can be applied with a cloth. Then, wipe the window surface with a cloth until it's completely dry.
Another option is to drill small holes into your double-glazed windows and tuck a desiccant packet inside, this will help absorb any moisture that has accumulated between the glass panes. This is a quick solution. It is important to keep in mind that the condensation will disappear after you have closed the hole.
Professionals can usually solve the issue of condensation by draught sealing or replacing the seal on the inside of the window. It is possible to repair the broken seal, but in some cases they may recommend replacing the entire window. If there is a large amount of condensation visible on the exterior of the window, they might suggest replacing the entire frame.
Misting
Double glazing is a good investment that will pay off in the long run. It will keep your home warm and block out outside noise. It also can save you money by increasing the efficiency of your energy. If your double-glazed windows begin to fog, you must immediately act to stop further damage.

You can also attempt to get rid of the fog yourself with a spray bottle that contains an anti-fog liquid. This is a time-consuming process and requires drilling holes into the double-glazed window. It's generally not recommended unless you're a competent DIYer.
If you have double-glazed windows that are still under warranty, call the installers to request a replacement. In most cases, a business will be able to repair or replace the sealed unit and even offer an additional warranty for windows.
Double-glazed windows that are blown occur when the seal between the two panes of double glazing break down, allowing cold air to get in and warm air to exit. The spacer bar in the glass is left with moisture, which then accumulates and appears as mist.

This will block out the elements and keep the buildup of moisture that can damage frames and cause decay.
Once the caulk has been applied, it is now time to fit the glass into the frame. The glass points are metal triangles that help to hold the glass in position.
