How to Properly Measure a Window for Glass Replacement

When a window or door glass pane cracks or breaks, replacing it can improve the look and feel of a home. But it is also important that the replacement fit correctly and accurately to ensure water, sunlight, and air can move throughout the house. A poorly fitting window can result in costly repairs, and it may even compromise your home’s energy efficiency. This article will provide tips and information to help homeowners measure their windows, choose the best replacement, and install new window glass in their homes.

How to Properly Measuring a Window for Glass Replacement

A common mistake that can make your new window fit poorly is getting the measurements wrong. For this reason, it is very important to get precise measurements before ordering your glass window panes. Start by removing any wood molding and glazing points from the frame. Then, sand the rabbet (the groove where the glass fits) until it is smooth and free of paint, putty, and other debris that could affect the measurement. Wipe the frame with a damp cloth to remove dust and dirt. Finally, apply a thin coat of linseed oil to the rabbet. This will make the caulk that holds the glass in place stick better and prevent it from coming loose in the future.

Once the window is open, measure from the inside edge of the sash to the outside edge of the frame for both the width and height dimensions. Take the smallest measurement for both to find out what size your window will be. Then subtract 1/8 inch from both measurements to account for expansion and contraction of the window frame in warm and wet weather. This will also give you an accurate measurement for the thickness of the glass.

Front Door Glass Replacement

The cost of front door glass replacement can range from $100 to $500, depending on the size and style of the window. This is one type of window that often requires the replacement of both the glass and the frame.

Patio Door Glass Replacement

Whether your patio doors are sliding or French, the cost of replacing glass in them can run from $150 to $1,200. This type of replacement typically involves the use of double-pane tempered glass, and the process can be more complicated than that of a single-pane window.

Glass Only Replacement

Glass only replacement is an option that can be a good solution for dated or leaky windows. However, it should be noted that it will not fix other issues such as problems with locks, balances, sashes, or rotting around the frame. Moreover, full window replacement is often more efficient in terms of energy consumption and costs. Nonetheless, you can still opt for glass-only replacement if it is a less expensive option.
