How to Hide Wires in Walls Without Cutting Drywall

Hiding wires in walls without cutting drywall can seem daunting, but with some planning and the right materials, it is very doable. As a homeowner looking to update my wiring without the mess and expense of drywall work, I have learned a few helpful techniques to conceal cables in a clean and attractive way.

Gather Supplies

• Drywall saw - Use to cut outlet openings and holes through framing. A keyhole or jab saw works well.
• Fish tape - Flexible steel wire for pulling cables through walls. Get one at least 15 feet long.
• Cable staples - To tack wires to framing studs. Get galvanized metal staples.
• Low voltage old work brackets - Plastic brackets to mount TV brackets or other devices.
• Wall plates - Match your existing switches and outlets.
• Caulk - For sealing cable entry points. Go with paintable silicone caulk.

Choose Pathways

When routing new wires without cutting drywall, you have a few options:

Through Existing Outlets

• Shut off power at the breaker.
• Remove existing outlet/switch covers. Check for available slack wire behind.
• Disconnect and pull out wires from the electrical box.
• Before pulling new cables, seal box openings with caulk to prevent air leaks.
• Use fish tape to route cables up into the wall cavity. Have a helper in the attic grab the tape.
• Reconnect the original wires, stuff everything back into the boxes, then replace covers.

Inside Wall Cavities

• Find cavity openings like soffits, channeier boxes, or duct chases.
• Use a drywall saw to cut new openings if needed, following framing lines.
• Feed fish tape into the bay, keeping it centered between studs.
• Staple cables loosely along the studs, leaving plenty of slack.
• Seal entry holes with caulk. Avoid fireblocking if possible.

Along Baseboards

• Remove baseboard trim carefully by prying up with a flat bar.
• Run cables underneath, centered behind the trim.
• Staple loosely to framing to prevent sagging.
• Reattach trim with finish nails. Caulk trim seams for a cleaner look.

Maintain Safety

When fishing cables through walls, keep these safety guidelines in mind:

• Turn off power at the breaker before starting.
• Handle live wires carefully if outlets can't be deactivated.
• Keep cable runs far from plumbing pipes and ductwork.
• Avoid fireblocking material between framing studs.
• Don't staple tightly or crimp cables.

With the right tools and some handywork skills, hiding wires without cutting drywall is very feasible. Just take precautions, plan routing carefully, and seal all openings neatly. The results will keep wall surfaces smooth and your wiring upgrades hidden.
