If you want to add a new window to your home, then you may find a perfect one which has brick molding around the edge. Fitting a window with such a decoration can be difficult as you need to know how to make sure that the window will stand perfectly against the edge of the wall. To do this, the first part of this guide will show you how to test the window against the rough opening, fit shim and remove any siding that prevents the window from fitting. You will then learn how to add a layer of building paper around the edge. Follow the steps below for a moderately difficult project.

Step 1 - Measure the Hole

To ensure that your window will fit well into the surface for which it was designed, you will need to test-fit the window into place. You may need some assistance here to get the right fit with a friend on the outside supporting the window. Place the window into the rough opening, and then apply shims against the jambs. The window should be fitted as closely as you can to the window.

Step 2 - Insert Shims

Place your shims against the horizontal jambs of your window frame. Tap them gently home. Use a spirit level between installing each shim to make sure that the window is still level. You may need to use several shims at a time to get the window plumb, but once this is fixed in place, you should not add or remove any more shims.

Step 3 - Clamp the Molding

Once you have done this, you need to clamp the molding into position. Use a firm grip, and then trace around the edge of the brick molding. You should now be able to see on the siding where you need to cut away more in order to fit the window fully against the wall.

Step 4 - Remove the Siding

Once you have this siding marked, remove the window, and begin to cut away at the siding. You may need to use a circular saw here to cut right through the siding in one go. In order to avoid splintering or damage to the siding, make sure that you cut it evenly, stopping before you reach the corner. Cut the edges of the corner free using a hand tool such as a chisel.

Step 5 - Add Builder's Paper

Builders paper is designed to fit underneath the edges of the siding, and then over the top of the window, in order to prevent water from running down through the siding, and touching the frame of the window.

Cut your builder's paper to the right size for your window. Pull up the siding a little, and slide it underneath the siding. Nail in place to prevent damage later.
