There are many different reasons why you might be left with a broken glass window in your home. It is possible that a confused bird flew into your window or a strong storm caused a tree branch to break your window pane. If you have a broken window on the first floor of your home, it may be possible that you can repair it on your own. There are a few DIY tips that make home glass window repair much simpler.

Prep Window First

One of the biggest tasks that you have when you want to repair a broken glass window is the prep work. You have to get the window ready for new glass installation. This involves removing all broken glass pieces from the window. The tips that you should follow involves taking the window sash out of the window opening entirely and placing it on a surface where you can use a covering to carefully dislodge all glass pieces.

Window Measurements

It is important that you purchase a glass pane that is cut to size. Trying to cut glass on your own can be tricky. However, as long as you have the exact measurements, it is possible to have the glass cut for you. It is important that when the glass is cut, the pane is smaller and narrower than those measurements to fit into the window sash.


Weatherproofing is a key component of glass window installation. When you are replacing a window, you need to make sure that it is weatherproofed. This is designed to ensure that all outdoor elements stay outside. You can weatherproof a window easily by applying a small layer of caulk on the frame perimeter. It is important to do this step before the glass window pane is actually installed. Once you have installed the glass window, you can then use a putty knife to press the putty into place firmly up against the window.

Roll Glazing Compound

Applying the glazing compound to the glass window to allow for the window sash to be put back on can be a complicated process. You can make it much more manageable by rolling the compound glaze in your hand and creating a rope-like shape that you can adhere to the glass and the wood framing around the glass. You can do this on all sides of the window and it will make putting the sash back in place much easier. The window sash should dry for a week before painting or applying any type of sealant.
