There are many advantages to window glass replacement projects in your home:

• Enhance your home’s appearance
• Increase your property value
• Save you money on your energy bills.

By installing DIY windows, you can save money on installation costs. However, it’s important that you complete your window glass replacement projects correctly, from choosing the right DIY windows to measuring and removing the old windows properly.

Choosing DIY Windows

Before you install a glass window replacement, consider the DIY window’s functionality, in addition to the style, which may be any of the following:

• Awning
• Bay
• Bow
• Casement
• Double-hung
• Fixed
• Garden
• Gliding/horizontal
• Hopper
• Jalousie
• Single-hung.

Most building suppliers familiar with DIY replacement windows will offer a fine selection of basic window styles. Specialty DIY windows, including those with shapes or unusual sizes, will most likely need to be special ordered.

If you are looking for replacement windows to save energy, look for the manufacturer’s label or an Energy Star symbol. A salesperson should be able to help you understand the numbers on these window glass replacement materials and replacement windows.

DIY: Measuring Windows

Installing windows DIY is difficult. It may be much easier if you get someone to help you with various tasks, from measuring to actually installing your window glass replacement.

Use a tape measure to determine the size and shape of your windows. A replacement window’s measurements should come with the manufacturer’s instructions. It’s best to use smaller replacement windows if you can’t find the exact fit. Installing larger windows may call for structural changes to the wall, which could require a city or county inspector’s approval.

Removing Windows

To remove the old windows and make room for the replacement windows, you’ll need the following materials:

• Caulking gun
• Hammer
• Level
• Pry bar
• Saw
• Screwdriver.
• Sharp utility knife
• Square
• Tape measure
• Wood chisel.

To make removing the old windows easier, you may also want to use a cordless drill/driver.

Remove the old windows and the outside trim, and then decide whether or not you’ll be keeping the inside trim. If you do decide to keep the interior trim, be sure to remove it carefully so that you can use it again. How much you remove will depend on your DIY replacement windows–be sure to follow the manufacturer’s directions.

Install Windows: DIY

The directions provided by the manufacturer will also be important for window glass replacement installation. Many replacement windows will come with instructions and identify specific places for nails. Before nailing, make sure that the window frame fits the size of the window. You may need to change the window frame’s size to accommodate a smaller window.

You may paint trim pieces before installing DIY replacement windows. After the installation, trim can then be fitted back on and any paint touch-ups done.
