How do you add additional wall outlets to walls that have existing outlets without tearing out drywall?

Answer 1

Sometimes you have to be creative.

Check the basement, if you have access to the floor just below the existing outlet AND the proposed new outlet, you can often drill a hole through the floor and into the wall space to feed wire through to the proposed outlet. If that isn't available, you can sometimes do the same thing through an attic space.

If neither is an option, you may need to punch a few holes through the walls and drill through existing framing materials to run your wires.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

Answer 2

You can use an extension cord with a power strip or a surface-mount outlet box to add additional outlets without tearing out drywall. Another option is to use wire mold raceways that can be mounted on the surface of the wall to run new wiring for additional outlets. Consult with a licensed electrician to ensure safety and compliance with building codes.
