Installing blinds in your windows can dress them up and make your home look complete. Blinds can be installed with an inside mount--inside the window frame--or with an outside mount--on the wall around the window. Many vinyl windows are placed in the wall with very little room for an inside mount. Look closely at your windows to determine if you have room to install the brackets on the inside of the window.
Hold the brackets up on the wall where you'll be installing the blinds. Mark the spots where you need to drill holes. Blinds more than 60 inches wide require a centre bracket in addition to the box brackets on each side.
Drill a hole into the wall where the screws will be installed. Insert wall anchors into the wall and tap them into place with a hammer.
Hold the bracket up to the holes and the anchors. Insert the screws through the holes in the bracket and into the wall anchors. Secure the brackets to the wall or window frame with the screws.
Insert the head rail into the brackets. Swing the covers over and snap the brackets closed.
Do not drill through the vinyl window casing. Damaging the window casing may void the manufacturer's warranty.
