Broken Glass
It is crucial to fix the damaged window as soon as is possible.

In many instances, homeowners will be able to fix the cracks without replacing the entire window pane.
The glass that has cracked must first be removed from the frame. This can be done by hand using the help of a putty knife, or any other deglazing tools. When dealing with broken glass, it is best to wear eye and hand protection. Once the glass has been removed, it should first be stored in a secure area prior to disposal.
After removing the old sealant, and the glazing points, the frame must be thoroughly cleaned using a wire bristle and a damp cloth. It is then a good idea to use the heat gun or hair dryer to soften the remaining glazing and sealant and make it easier to take off. After cleaning the frame it is recommended to apply a small amount linseed to the rabbets in which the glass is to be placed to ensure that the glass adheres strongly.
Then cut the glass to the appropriate size to ensure that it fits in the frame. If the gap is very large, you can use an individual piece of glass repair film to fill in the space and hold the glass. If the gap is smaller then you can apply a piece of clear tape or concealing film to both sides of it to keep it from expanding.

It is then a good idea to touch up the paint on the frame if it is required. If the glass has a wood frame around it, you must remove these pieces before installing the new glass.

Condensation
Condensation is a common problem with double glazing. If condensation is present, you should ventilate the room as often as you can, especially in times of high humidity. This will help to reduce condensation. A dehumidifier is also useful. If you are unable to stop the condensation, you should seek out a professional as quickly as you can to repair your windows.

It is also advisable to contact them to see if they can offer suggestions and guidance on how to prevent condensation in the future.
One method of removing condensation from your double glazing is to use a non-abrasive product such as iron oxide or cerium oxide that can be applied with the help of a cloth. Then, you should clean the window until it is dry.
Another option is to drill tiny holes into your double glazed windows and then tuck a desiccant bag inside. This will absorb any moisture that has accumulated between the glass panes. This is a great short-term solution. However, it is important to remember that the condensation should go away after the hole has been sealed.
Professionals can solve the problem by replacing the seal within the window or sealing the draughts. This can be accomplished by simply replacing the damaged seal but in some cases, they might recommend changing the entire window. If there is a significant amount of condensation visible on the exterior of the window, they might suggest replacing the entire frame.
Misting

Double glazing is an investment that pays off in the long term. It will keep your home warm and block out outside noise. It also improves your energy efficiency, thereby saving you money on heating expenses. If your double-glazed windows begin to fog, you must immediately act to prevent further damage.

It's not recommended unless you're an experienced DIYer.
If windows with double glazing are still under warranty, contact the installers to request a replacement. In many cases the company will be able to repair or replace the sealed units, and offer a warranty for the new windows.
Double-glazed windows that are blown happen when the seal cracks between the two panes, allowing cold air to enter the window, and warm air to escape. This creates a spacer bar inside the glass filled with water that eventually accumulates and causes a cloudy appearance. While it's possible to repair blown double glazed windows by replacing the glass, this does not solve the condensation already in the window.

After the putty has been removed, take out any clips or nails from the frame. Then, clean the wood using a wirebrush until it is free of dirt and painted.
Reassembling your double-glazed window frame is possible after the wood is cleaned and sanded. It will also be coated with a sealer that protects. It's a good idea to use a caulk gun to apply a thin layer silicone sealant on the edges of the frame, both inside and out.

Once the caulk has been applied, you are now able to place the glass in the frame. The glass points are metal triangular triangles which hold glass in the frame. They should be pushed firmly into the frame and then pressed against the glass or putty to ensure that they do not move. You can then apply more glaziers compound to the frame and glass. Allow it to dry before painting. This should be done to match the rest of your windows. You'll need to replace any molding or trim removed after the frame was taken down.
