DIY Instructions for Window Sash Replacement

After a thorough inspection of your home windows you may discover that it’s time to order Window Sash Replacement kits. If you are a skilled handyman you can perform this work yourself. If the project seems a little overwhelming you should hire a professional contractor in the Joliet, Naperville, and Plainfield area to remove your old windows and install a new Window Sash Replacement kit.

Step 1: Window Inspection

The first thing you need to do is inspect your windows to determine if a Window Sash Replacement Kit is all you need or if it’s time to replace the entire window assembly including the window frame and window sill.

Step 2: Measure the Window Opening

Before you purchase or order your new window sash replacement kit, carefully measure the existing sash opening. Measure the distance from Jamb to Jamb to determine the width. To measure the height; you will need to open the bottom sash and measure from the point where the exterior of the lower sash meets the window sill vertically to where the interior of the top sash contacts the window frame.

Step 3: Determine the Window Sill Angle

The standard angle of most window sills is 14 degrees. It is a good idea to confirm this by measuring the window sill angle with a protractor or angle level. You will need all of these measurements when you place your order for new window sash replacement kits.

Step 4: Remove the Existing Window Sash and Components

Your new window sash replacement kit should consist of all window components required for your project. This includes a pair of window sashes, all mounting clips, a new parting stop, and jamb tracks. Before you remove your existing sash and components check to be sure your new kit is complete and is the correct dimensions.

Using a utility knife; score the paint between the bottom stop and the window frame. Carefully pry the stop away from the frame so it can be reused if it is in good condition.
Use the same procedure to remove the sash parting stop, although your new window sash replacement kit should include a new sash parting stop.

Step 5: Install Additional Insulation

This is a great opportunity to improve the efficiency of your windows. Fill the exposed cavity with insulation.

Step 6: Install New Mounting Brackets

Following the instructions in your window sash replacement kit; install the mounting brackets, new sash stops, gaskets, jamb liner, and sash stop strip.

Step 7: Install Window Sashes

Carefully insert the upper and lower window sashes. The upper sash will be installed first by inserting it into the exterior track. Slide the upper sash all the way to the top of the track. Insert the lower sash into the inner track and slide it down until it contacts the window sill. Latch the window lock.

Step 8: Replace Interior Casing

With the window in the closed position, finish off the installation by replacing the interior casing, and repaint as necessary.
