Bay windows are a special architectural feature on a home, but since they project out from the house, window panes are more likely to get broken than other types of windows. Whether the glass was broken by baseballs, snowballs or debris blown in by heavy winds, you will need to find a way of replacing it.

Employing a professional to replace the broken pane can be expensive, which may prompt to to try and fix it yourself. Replacing broken glass in a bay window is actually easy and, if you have the right tools and materials on hand, you shouldn't have a problem with this project.

Step 1 - Removing the Broken Glass

The first thing you need to do is remove the piece of broken glass from the window frame. Wear gloves when doing this to protect your hands. Scrape our any putty and remove the glazing points so that the glass can be lifted out easily.

Step 2 - Replacement Glass

Replacement glass is needed to replace the broken pane of glass in your window. If the glass has broken then measure the inside of the window frame. If the glass is still intact, you can use this as a template to measure for the new piece of glass. While it is possible to cut glass yourself, if you dont' have experience with glass cutting it's best to buy glass that is already cut to shape. Also ensure that the thickness glass is the same as the existing glass.

Step 3 - Preparing the Wood

You now need to prepare the wood frame for the new piece of glass. Scrape out any glazing compound using the putty knife so that the glass will be able to fit inside properly. Sand down the wood frame as this will be easier before the wood is fitted, you can then apply primer and stain or paint.

Step 4 - Glazing the Window

Now place the replacement pane of glass into the window frame and hold it firmly in place. The glazing points can then be pressed into the wooden frame to help secure the glass. Make sure that you apply enough pressure to keep the glass in place, but not too much so that the glass won't crack.

When the glass in securely, you need to use putty to secure the glass in place. Glaze can be brought in tubes and applied using a chalking gun, or used from a tin. Make sure that the glazing is at an angle so that the water runs off instead of collecting in the joints. Using a wet finger or damp putty knife you can shape the putty.

Step 5 - Painting

Allow the glazing plenty of time to dry and you can then paint it so that it can match the color of the frame.
