Not a bit. In most cases, all you will need is a screwdriver. Many brands are self-adhesive and will automatically stick to the wall or ceiling where they are placed. However, be sure to follow the directions from the manufacturer because each brand is different. If you are uncomfortable standing on a ladder, ask a relative or friend for help. Some fire departments will actually install a smoke alarm in your home for you. Call your local fire department at 478-277-2911 (again, on a non-emergency telephone number) if you have problems installing a smoke alarm.
