Condensation can damage the seal on your double-pane windows and structural integrity. If you're a building or homeowner with a problem like this, there are several solutions that you can think about before committing to a more permanent solution.
Find the height and width of the frame opening. Subtract 1/8-inch from each measurement to get glass panes that are slightly undersized, which will make it easier to install and allow the room for seasonal expansion and contraction.

Cracks
Cracks in windows can be caused by a pebble thrown by your lawnmowers, a vase knocked over by a pet or an abrupt change in weather. Generally speaking, these kinds of cracks can be repaired at home if you're willing to invest a little time. But, if your crack is larger than an inch, a single-pane window or double-paned glass that has an opening through both panes, it is recommended to seek out an expert to fix the damage.
Repairing a small crack or a gap at the frame's edge by applying an edging strip of clear packing tape either side. This will help keep the crack from growing and will also seal off the gap to the outside, blocking wind, rain, bugs and other debris. This is a temporary fix, as glass cracks usually spread over time.
Use a two-part epoxy for larger cracks. First, you must thoroughly clean the area affected and take out all pieces of broken glass. Mix the epoxy in a place that is well ventilated on a piece of paper plate. The mixture is typically a 50/50 blend of hardener and resin, however, you must adhere to the directions for the specific product you are using. When mixed, the epoxy becomes thick quickly and must be applied immediately. Apply the adhesive and smooth it in the desired location using your putty knife. Allow it to dry for five minutes.
Another DIY solution to fix cracks is to use clear nail polish. The nail polish functions similarly to super glue. It fills and bond the cracks, stopping them from spreading. Make sure you allow the nail polish to completely dry, as cleaning or washing the area can cause it to come off. You can also use the caulking gun for filling in any gaps between your frame and glass. This is essential, especially for windows that are getting old. These gaps could allow water and other elements into the home.
Leaks
If it's a result of a reckless baseball or a badly planned furniture move in the home, accidents at indoors are among the main causes of cracked windows. The weather, including strong winds, can also cause the glass to break out of its frame. Caulking is a method to repair cracks in glass. This repair method can be done with either polysulfide or silicone caulking depending on the type of window glass and the materials used to make the frame.
The ideal time to complete this repair to your window is when the conditions are dry and warm. This allows you to apply the sealant in a dry setting and allow it to set before exposing it to rain. It's important to inspect the window from the outside and inside to determine where the leak is. It's also worth checking that the weep holes are free of obstructions such as insects' corpses and other debris, since this will help stop water from leaking through the bottom of the frame.
If you notice a water trail that's indicating the window is leaky or leaking, use a pry bar to take off any trim to get a better look at the joint between the frame and sash. If you notice rot, then this will need to be replaced with a wood filler product prior to applying the caulking. After cleaning and sanding the surface, caulking is applied. It should dry overnight.
Another type of leak is one that's structural, usually resulting from an unsound or damaged wall around the window. It's more difficult to detect, as it's usually not directly under the window. If you do notice damp patches on walls in the vicinity of the frame, then it's likely that there's an opening somewhere in the wall that is permitting water to enter and then get into the window studs.
In this instance it's recommended that an expert assess the situation and recommend a proper method of action. If the problem is severe then it's an ideal idea to replace the window entirely, which will allow you to enjoy improved energy efficiency in your home.

This process can be messy, but it's necessary to ensure that the glass will fit in the window frame.
Make use of a scraper once the wood that is bare has been exposed to smooth it. If needed, a chisel may be used to take off any wood molding that is too tight or glued to the window frame. Then you can sand the wood using fine-grit sandpaper. Seal it by putting linseed oil on it or using clear window caulk to stop mold or rot.
While you can install a single windowpane within a wooden frame with some practice, double-glazed windows require the assistance of professionals to avoid problems. Double-glazed windows differ in size from single panes and should be designed by an expert to ensure they are properly fitted.
