Converting an Andersen Double Hung Window to a Tilt-wash Window..

Converting your windows to a tilt-wash window is much easier than one would expect, and it can be done from the inside of the home with no change to the exterior trim. Because the frame remains the same, and because Andersen has a conversion kit available, any homeowner moderately handy with tools can accomplish what looks to be a daunting task.

The first step in any do-it-yourself project is really to gather the materials and supplies you will need.

Andersen Conversion Kit
Flat-bladed screwdriver
Phillips-head screwdriver
Tape measure
Putty Knife
Silicone Caulk
Wire cutters
2 drywall screws (1/2 inch)
Rubber Mallet
Silicone-based lubricant

Step 1

You will need to measure the visible glass dimensions of your existing window, which includes just the glass that you can see and touch, to determine what size of conversion kit you will require. If you have a cottage-style window, or a window where the lower sash is taller than the upper sash, please measure both sash. Then, match those dimensions up to a unit size in the Narroline parts catalog on pages 7-12 depending on the age of your window.

Step 2

You will notice that one side of the track (referred to as the jamb liner) is made up of an upper and lower piece. Remove the screws from the lower side of the track, and carefully pull this piece down and away from you to remove it from the window. Optionally, you can remove the trim on the side of the window by breaking the stain or paint seal, and prying it off with a firm putty knife. Be carefully to replace any screw that is longer than 1/2", as they are used to connect an adjoining window.

Step 3

Lower both sash to the sill, and cut the cords on either side. Do this as close to the top of the window as possible, as they are under a lot of tension, and can snap away, damaging you or the window. Proceed to removing the other side jamb liners, and the head jamb liner. You are then able to remove both sash from the window.

Step 4

Prepare the frame of the window by removing any debris around the perimeter of your frame, and run a thin line of caulk on either side of the window. Place the new jamb liner retainer where your old jamb liner went. It will fit flush to the top and bottom of the frame. Make sure the retainer is tight to the side of the frame, and tap the sides with a rubber mallet if necessary so they are flush with the frame. Place your new jamb liners into the retainer.

Step 5

Using a flat bladed screwdriver, turn the balance 90 degrees so that it will receive the pivot pin on either side of your new sash. Place both pivot pins of the upper sash into the balance slots in the jamb liner, and tilt the window into place. Compressing the jamb liner on either side will make it easier to tilt the upper sash in. Raise the upper sash to the top of the frame. The balances will keep the sash in place. Repeat the procedure for the lower sash, and you now have windows that tilt in to clean.
