A wired doorbell is a cheaper option than the wireless. The doorbell will connect to the electrical wiring of your home. The bell on the outside of your home is wired to the chime box inside. Installing a new doorbell is a quick and easy home improvement that will have a large impact on the appearance of your home. Many older homes have large chime boxes. Modern chime boxes are much smaller and blend in more easily.
Turn off the power supplying the doorbell at the breaker box. Use a screwdriver to remove the screws holding the doorbell to the side of the house. Pull the doorbell and wiring away from the house. Use a circuit tester to ensure no electricity is running through the wires.
Loosen the screw terminals on the old doorbell, and remove the wires. Wrap the wires around the screw terminals of the new doorbell and tighten them in place.
Remove the screws from the chime box so you can pull the box away from the wall.
Take the wires off of the screw terminals of the chime box one at a time. Wrap a piece of masking tape around each wire as you remove it, and write which terminal it was attached to.
Pull the cover off the new chime box. Thread the wiring through the available hole on the back of the unit. Put the unit flush with the wall and mount it with screws.
Connect each wire to the proper screw terminal. The wires will be wrapped around the terminal. Use a screwdriver to tighten the screw to hold the wires in place.
Push the cover of the chime unit in place. Restore power to the doorbell.
