Round windows are one of those windows styles that come and go from the mainstream. If you are choosing to install a window, you might not know exactly how to do it. You could either call a window installation company or you could try to do it yourself. If you choose to do it yourself after you have put up the sheathing, here are the steps that you are going to need to follow.

1. Get the Outline of Your Window

Grab a large piece of cardboard and put your round window down on top of it. Trace around the window with a pencil and cut out what you just traced.

2. Transfer the Image to the Sheathing

Next, tape the cardboard circle to the sheathing and trace around it. Don't be afraid to move it around until you have the cardboard in the precise spot that you want the window. Erase any stray lines.

3. Bore the Access Hole

Next, remove the cardboard. Take a drill and drill a medium-sized hole in the sheathing on the edge of the circle that you traced. This is known as the access hole and is used as a point of entry for the rotating saw that you are going to use to cut out the area.

4. Cut Out the Area With a Rotating Saw

Stick the rotating saw into the access hole and cut as closely to the circle that you traced as you can. Go slow to make sure that you don't veer off the line.

5. Press the Casing into the Hole

Take the casing that fits your window and press it into the hole. Have another person hold it while you firm up supports by adding strips of wood near the studs that will help hold it one place. Make sure that the casing is perfectly centered in the hole that you have cut before you start solidifying its support. Add caulk if necessary in order to make sure that the casing does not slip around.

6. Insert the Window

Finally, insert the window into the casing so that it does not move around. Add caulk or some other window sealant if you think it's going to need some extra support. Otherwise, your job is done. All you need to do is cover the rest of the sheathing with tile or with siding that matches the wall surrounding it.
