Cracked glass isn't just unsightly but can also let valuable sunlight and heat escape from your home. It's possible to fix a broken pane of glass without replacing the entire window.

This high-tech glue was designed to attach to glass and then dry transparent to give a perfect finish. Apply it to the cracks in the glass and let it dry completely before applying another layer.

Glass windows can also develop stress cracks. Stress cracks are usually caused by extreme temperature fluctuations and can rapidly spread across the entire window if they are not fixed. To prevent stress fractures using a glass cutter, you need to score a small arc near the crack. This stops the crack from spreading and may slow it down by a day or two.

Measure the frame of the broken window to determine the size of the new pane. It should be slightly bigger than the opening in order to allow for expansion and contraction and to account for any imperfections on the frame or on the glass. After cutting your new glass, apply glaziers compound around the edges of the frame and glass. Once the compound is dry then paint it over it to match the rest of the window frame.

It is more prevalent in winter, when temperature is lower. This makes it easier to create condensation. The primary reason for this is a defect in the spacer that is used between the frame and the window. The spacer is filled with desiccant which is very absorbent and will soak up any excess moisture.

This could result in moisture leaking into the gap once the desiccant is saturated. This can lead to condensation and water leaking into the gap, which is difficult to eliminate.
