Picture this: you’ve mounted your TV (nice job by the way). It’s straight, beautiful and ready for viewing, but those cords dangling below are ruining the vibe. Did you know you can hide them inside your walls? It’s a simple project that elevates your living room and makes your TV more like artwork than a screen.
Anytime you’re going into the walls, it can feel intimidating, but trust me, you can do this without a pro. In this blog, we’ll go over everything you need to add this DIY to your “done” list.
Why Hide Your TV Cords in the Wall?
Clean, minimalist look — no more messy wires.
Safety (especially with pets or kids around).
It adds value and polish to your space.
Feels like a "pro" move — even though it’s beginner-friendly!
What to Know Before You Start
Before you get started, there are a few important things to know. This project is for low-voltage cords only — meaning HDMI, Ethernet, or coaxial cables. You can’t run a regular power cord behind drywall unless it’s specifically rated for in-wall use or you’re installing an in-wall power kit, which safely relocates an outlet behind your TV. Also, make sure the wall you’re working on is not load-bearing and doesn’t contain plumbing or major HVAC lines. A stud finder with wire detection can help you check. Lastly, this type of cord-hiding setup works best if your TV is mounted on the wall, since that creates a natural entry and exit point for your cables.
Tools and Materials You’ll Need
Stud finder
Tape measure
Pencil
Level
Drywall saw or utility knife
Fish tape or a wire snake
In-wall cable management kit (or wall plates with grommets)
HDMI cables, power bridge kit (if needed)
Screwdriver or drill
Step-by-Step Guide: How to Hide TV Cords in the Wall
1. Plan Your Path
Decide where the cords will enter and exit the wall. Usually one hole behind the TV, one near the outlet.
2. Find the Studs
Use your stud finder to locate and mark the space between studs. This is where your wires will run vertically.
3. Cut Your Holes
Trace the wall plates where they’ll go. Carefully cut out the drywall with a multitool, drywall saw, or even a utility knife.
4. Feed the Cables
Use fish tape to guide HDMI, coaxial, or Ethernet cables down the wall. Pull them through the bottom hole. Use a power bridge kit if you're hiding a TV power cord (emphasize safety again here).
5. Install Wall Plates
Attach the wall plates or grommets for a polished look. Secure with screws and tighten them so they sit flush.
6. Mount Your TV and Connect Everything
Run cords from TV into the top plate. Plug into the bottom — no visible wires!
Common Mistakes to Avoid
Mistake: Running regular power cords in the wall (illegal and unsafe).
Fix: You only want to run HDMI, Ethernet, or coaxial cables in your wall. Double check that your TV uses these.
Mistake: Not checking for obstacles (pipes, wires).
Fix: Use a stud finder to ensure you won’t encounter anything but drywall and maybe insulation when you open the wall. You don’t want to cut into pipes or wires. A stud finder will alert you to anything behind the walls.
Mistake: Cutting too large of a hole.
Fix: To avoid doing this, trace your finishing plates or even aim to cut a smaller hole. You only need it to be big enough to fit the plug. If you do cut the hole too big, you can use a patch kit to fill the hole or most of the hole.
Mistake: Not using plates
Fix: Use wall plates to hide the holes in the wall and make the entire project look finished and professional.
As you begin this project, remember to take your time. Measure twice and only make holes once. Watch a few quick tutorials if you’re nervous — it's easier than it looks! This little project can make a room feel professionally designed.
