Broken Glass
Cracked windows aren't just unattractive, but also let valuable heat and sunlight to escape your home. Fortunately, it's possible to repair a broken window without the need for a complete replacement.
Begin by putting on protective gloves and safety goggles. Also, you should put an X-shaped piece of tape an "X" shape on the glass you intend to remove (duct or painter's tape work well). This will prevent any broken glass from falling onto you while you work.
If you've got a tiny crack in your window glass, cover it with tape to block the elements like wind, water, and insects. If the crack is superficial, a single strip of tape is enough.

Glass windows can also develop stress cracks. Stress cracks are typically caused by large temperature changes and can spread rapidly across the entire window if they are not fixed. To stop stress cracks from occurring create an arc using glass cutters close to the crack. This stops the crack from spreading, and can slow it down by a day or two.
If you're replacing a damaged window take measurements of the frame to determine the size of the new pane. It should be slightly smaller than the opening to allow for expansion and contraction, and to compensate for any imperfections in the glass or frame. Once you've cut the glass to size apply glaziers' compound around the edges of both the frame and the glass. Once the compound is dry, paint over it to match the rest of the frame.

If you've got condensation on your double glazed window and you are unable to resolve it by opening the windows by using extractor fans, dehumidifiers or by trickle venting, you might need to contact a professional.
It's rare to see condensation appear on the outside of double glazed windows, but it could happen in the event that the seal between the glass and window frame is beginning to break down. It is more prevalent in winter, when temperature is lower. This makes it easier for condensation to form. This is due to an issue in the spacer that is used between the frame and the window. This spacer often contains desiccant that is highly absorptive and absorbs excess moisture.
The issue with this is that when the desiccant becomes saturated it will start to break down and moisture will begin to enter the gap between the glass units. This could lead to condensation and water in the gap and is very difficult to eliminate.
Most reputable window companies offer a warranty and will replace the glass and unit of a window in the event that it is damaged by condensation. Report any problems as soon as you can to the window manufacturer so that the condensation can be repaired as fast as possible to avoid further damage.
