How to Do Your Own Vinyl Window Installation

Installing a vinyl window is a task that you can accomplish with some basic carpentry skills. Vinyl windows are excellent for their energy efficiency and have improved over the years. Even if you have vinyl windows now, they are likely not as efficient as newer models. Vinyl also holds up exceptionally well against the elements, requiring very little maintenance. That being said, nothing lasts forever, and new windows are an easy and cost-effective way to improve the look and value of your home.

Things You'll Need

• Electric saw
• Level
• Shims
• 1-by-4 lumber
• Screw gun and screws
• Hammer and nails
• Batt insulation

Instructions

How to Install a Vinyl Window

1. Cut out the existing window with an electric saw. The window may be screwed or nailed in place, or you may have to cut through the nailing flange that secures the window to the outside of the home. Cutting through the nailing flange lets you avoid removing the exterior surface on the house.

2. Use the level to ensure that the opening is level. Place the level on the bottom stud on which the window will be resting. If the stud is not level, you can use the shims and 1-by-4 lumber to create a level surface.

3. Place the vinyl window in the opening. Use shims to create a snug fit of the window in the opening. Do not force the shims too tightly because that may affect the window's operation.

4. Screw through the window's vinyl frame to secure the window in place. Replacement windows have small, vinyl inserts that are removed to access the screwing area and replaced to cover the screw. Ensure that the top, bottom and sides of the window are level. You can use the screws to adjust the window.

5. Rip or cut small strips of batt insulation to fill any gas between the window and the studs. Use a shim to stuff the insulation into place. All that is left is to finish the interior with your choice of trim or drywall and to seal the exterior with aluminum and caulk.

Tips & Warnings

• It is best to order replacement windows slightly smaller than existing windows. This will give you room to re-frame the window opening if it is not square.

• While interior trim is another fairly simple task, exterior trim is best left to a professional because it is crucial that it be done right to protect your home from water damage.
