What to Do With the Cables Behind a Wall-Mounted TV: Complete Guide
Visible cables are the #1 complaint about wall-mounted TVs. Here's every method to hide them — from professional in-wall concealment to budget-friendly cord covers.
You just mounted your TV on the wall. It looks amazing — until you see the cable waterfall. Power cord, HDMI cable, streaming device wire, maybe a coax cable, all dangling down the wall in plain sight. Visible cables are the single most common complaint about wall-mounted TVs, and they're the reason most people end up calling us after attempting a DIY install. The good news? There's a solution for every situation, every budget, and every wall type.
Our wire concealment service is our most popular add-on across Kennesaw, Marietta, Woodstock, and the entire Metro Atlanta area. Here's everything you need to know about hiding cables behind a wall-mounted TV.
Method 1: In-Wall Cable Concealment (The Gold Standard)
In-wall concealment routes all cables inside the wall cavity, completely hidden from view. This is the professional standard and the method we recommend for every permanent installation.
How It Works
- Cut a small access hole behind the TV
- Cut a matching hole near floor level (behind furniture or equipment)
- Route low-voltage cables (HDMI, ethernet, coax) through the wall cavity
- Install a low-voltage bracket or wall plate at each hole for a clean finish
- For power: install a recessed outlet behind the TV (or use a code-compliant power relocation kit)
⚡ NEC Electrical Code: What You Need to Know
Critical: The National Electrical Code (NEC) prohibits running standard power cables (Romex, extension cords, power strips) through wall cavities. This is a fire hazard and code violation. Legal options for power:
- Recessed outlet behind TV — a licensed electrician installs a new outlet at TV height. This is the cleanest solution. Our outlet installation service handles this.
- Power relocation kit (PowerBridge) — a UL-listed kit that creates a code-compliant power pathway through the wall. No electrician required.
- Surface-mount power raceway — keeps the power cable outside the wall in a paintable channel. Code-compliant but visible.
Low-voltage cables (HDMI, component, ethernet, speaker wire) CAN legally run through wall cavities without conduit.
Method 2: Surface-Mount Cable Raceways
Cable raceways are plastic or metal channels that mount to the wall surface and conceal cables inside. They're not invisible, but they're a huge improvement over exposed cables.
Pros
- No wall cutting required — rental-friendly
- Paintable to match wall color
- Easy DIY installation with adhesive or screws
- Accommodates power cables (since they're outside the wall)
Cons
- Visible on close inspection (though paintable)
- Can look bulky if too many cables
- Adhesive versions may fall off textured walls
Best For
Renters, temporary installations, or situations where wall cutting isn't possible (concrete, brick without desire to cut channels).
Method 3: Fabric Cord Covers
Fabric sleeves wrap around cable bundles, creating a single fabric-covered "cord" running down the wall. Available in various colors and patterns.
- Cost: $10-$25
- Installation: 5 minutes, no tools
- Aesthetics: Better than bare cables, not as clean as raceways or in-wall
- Best for: Budget solution while you save for professional concealment
Method 4: Strategic Furniture Placement
Sometimes the simplest solution is the best: position a console table, floating shelf, or tall plant below the TV to hide the cable run. Cables still exist, but they're hidden behind furniture rather than in the wall.
Method 5: Wireless Solutions
Reduce the number of cables by going wireless where possible:
- Wi-Fi streaming: Smart TVs and streaming sticks (Roku, Fire Stick) eliminate the need for HDMI runs to cable boxes
- Wireless HDMI transmitters: Send video wirelessly from a device to the TV — no HDMI cable through the wall. Latency has improved dramatically in recent models.
- Bluetooth soundbar: Eliminates the audio cable between TV and soundbar
The one cable you can't eliminate: Power. Your TV always needs a power cable, which is why a recessed outlet behind the TV is the ultimate solution.
Cable Management for Different Wall Types
Drywall (Standard)
In-wall concealment is straightforward. Cut holes, fish cables, install plates. This is our most common installation across Kennesaw, Marietta, and Metro Atlanta homes.
Brick and Stone
In-wall routing isn't possible through solid masonry. Options include:
- Surface raceways painted to match the brick/stone
- Routing cables through adjacent drywall and transitioning at the corner
- Chasing a channel into the mortar joints (destructive but hidden)
Concrete
Similar to brick — surface raceways or conduit mounted to the concrete surface. Industrial-style exposed conduit can actually look intentional in modern/loft spaces.
Plaster
In-wall routing works but requires more care. See our plaster wall guide for details on working with plaster and lath.
💡 Pro Tip
When we do in-wall cable concealment, we always run an extra HDMI cable and a Cat6 ethernet cable — even if the customer doesn't need them today. An extra $5 in cable now saves $150+ in future wall access if you add a gaming console, streaming device, or want a wired connection later.
DIY vs. Professional Cable Concealment
| Factor | DIY | Professional |

| Time | 1-3 hours | 30-45 minutes |
| Code compliance | Risk of violations | Guaranteed compliant |
| Finished quality | Variable | Professional-grade |
| Warranty | None | 5-year workmanship |
What Cables Do You Need Behind a Mounted TV?
- Power cable: Always required. Route through a recessed outlet or PowerBridge kit.
- HDMI 2.1: For 4K/120Hz gaming and streaming devices. One or two is standard.
- Ethernet (Cat6): Optional but recommended for stable, high-bandwidth streaming.
- Coaxial: Only needed for cable TV or antenna connections.
- Optical audio (TOSLINK): Only if your soundbar lacks HDMI ARC.

Frequently Asked Questions
Is it legal to run TV cables through the wall?
Low-voltage cables (HDMI, ethernet, coax, speaker wire) can legally run through wall cavities. Power cables (AC power, extension cords) CANNOT run through walls without proper conduit or a UL-listed power relocation kit. This is an NEC code requirement, not a suggestion.
How much does professional cable concealment cost?
Professional in-wall cable concealment typically costs $75-$200 depending on the number of cables, wall type, and distance between the TV and equipment. Most customers pay $100-$150 when bundled with a TV mounting appointment.
Can I hide cables in a rental apartment?
Without cutting into walls, your best options are surface-mount cable raceways (paintable, removable), fabric cord covers, or strategic furniture placement. Some landlords allow small wall modifications if you agree to patch before moving out — always check your lease.
What's the best wireless alternative to running cables?
A smart TV with built-in Wi-Fi streaming eliminates HDMI cables for content. A wireless HDMI transmitter handles gaming consoles or cable boxes. The only cable you truly can't eliminate is power — a recessed outlet is the permanent solution.
Should I hire an electrician for the power outlet?
If you want a new recessed outlet installed behind the TV, a licensed electrician (or our team) should handle it. If you want a simpler solution, a UL-listed PowerBridge kit can be installed by anyone and is fully code-compliant.
