What You'll Need
Vinyl siding

If you are thinking of installing vinyl siding around your home, but have a bay window which you are not sure how to apply the siding to, then you may be unsure how to proceed. A bay window can be an awkward thing to fit any facing on, and the stiffened siding can be somewhat difficult to place around curves and lumps at the best of times. Nevertheless, if you are prepared to do the work, and you have a friend who is willing to help you, then you should be able to install vinyl siding around a bay window. With some basic home improvement skills, and by following a few simple guidelines, then you should be able to complete this project quickly and efficiently.

Step 1 - Install the Vinyl

The first step you need to take is to install vinyl siding around the rest of the house. If your bay window is on the second floor, then you should install all of the vinyl on the first floor without any problems. When you come to the bay window, place the vinyl siding on both sides as closely as you can, and screw it tightly to the wall at the edge of the window. On the approach to the bay window, keep the vinyl siding as flat as possible, and secure it at regular intervals so that it is defended against wind traveling under the siding.

Step 2 - Prepare the Window

Place the tape around your window so that the glass is completely secured. Double-sided tape can be useful here, as you might be able to press the siding into this tape while you are setting it up. Take the first piece of siding, and place it against the main fabric of the bay. You may find that it does not settle evenly against the window, so you may have to cut it off below the level of the window frame. Get your friend to assist you by holding it up against the frame while you use the saw on the top of the vinyl. Screw the first piece into place.

Step 3 - Installing the Vinyl

Once you have installed this first part, you can then proceed to install the other pieces of the siding. Don't cover the whole of the bay window with just one piece, but rather cut it to fit the curve of the window. You may need to use 4 or 5 pieces, overlapped tightly, to ensure that the whole of the curve is covered by the siding. Screw the vinyl in at regular paces, making sure that you don't leave wide gaps in the siding.

Step 4 - Finishing

When you have installed all of the vinyl, and all of the screws have been placed very tightly into the wall, you need to apply a layer of water-proof caulking over every edge, and the area where the screws have penetrated the vinyl. Leave to dry for around 24 hours.
