You finally mounted your TV on the wall. It looks incredible — until you step back and notice the tangle of cables dangling down to the outlet, the streaming stick, and the soundbar. Suddenly your sleek setup looks like the back of a college dorm entertainment center.
Hiding TV wires is the finishing touch that separates a professional-looking installation from a rushed weekend project. But with multiple methods available — each with different costs, skill requirements, and code implications — choosing the right approach matters.
This guide covers every cable concealment method from simplest to most polished, including the electrical code requirements that most DIY guides skip entirely.
Understanding What You're Working With: Cable Types Matter
Before choosing a concealment method, you need to understand a critical distinction that affects both safety and legality:
| Cable Type | Examples | Can Run Inside Walls? | Code Requirement |
|---|---|---|---|
| Low-Voltage | HDMI, Ethernet, coax, speaker wire, USB | ✅ Yes | CL2 or CL3 rated for in-wall use |
| High-Voltage (Power) | TV power cord, extension cords, power strips | ❌ No — fire hazard | Must use NM-B (Romex) or approved in-wall power kit |
The #1 mistake homeowners make: Running a standard TV power cord through the wall. This violates NEC (National Electrical Code) Article 400.12 and creates a genuine fire risk. The cord's insulation isn't rated for enclosed spaces where heat can't dissipate. Learn more in our guide to outlets behind wall-mounted TVs.
Method 1: Surface-Mounted Cord Covers (Easiest)
Best for: Renters, budget setups, temporary installations
Cord covers (also called raceways) are plastic channels that attach to the wall surface and hide cables behind a snap-on cover. They're the simplest solution and require zero wall modifications.
How It Works
- Adhesive-backed or screw-mounted plastic channels run vertically from TV to outlet
- Snap-on covers conceal all cables inside
- Can be painted to match wall color
- Available in various sizes for different cable bundles
Pros and Cons
| Pros | Cons |
|---|---|
| No wall damage — renter-friendly | Visible channel on wall surface |
| $10–$25 for a complete kit | Adhesive may damage paint on removal |
| 15-minute installation | Doesn't solve power cord code issues |
| No tools required (adhesive type) | Can look cheap if not painted to match |
Cost: $10–$25 DIY

Method 2: In-Wall Cable Pass-Through Kit (Moderate)
Best for: Homeowners who want clean results without full electrical work
Pass-through kits use two wall plates — one behind the TV and one near the outlet — with an open wall cavity between them for routing low-voltage cables. Many kits include a code-compliant power solution.
What's Included in a Typical Kit
- Two low-voltage wall plates (upper and lower)
- Grommet or brush-style cable openings
- Some kits include a power extension with NM-B rated wiring
- Fish tape or pull string for routing cables
Installation Requirements
- Drywall walls only (not suitable for brick, stone, or concrete)
- Must avoid insulation, fire blocks, and horizontal framing
- Stud finder to locate and avoid framing
- Drywall saw for cutting plate openings
- Both plates should be in the same stud bay (between the same two studs)
Cost: $40–$80 for a quality kit + 1–2 hours installation time
Method 3: Full In-Wall Wire Concealment (Professional Grade)
Best for: Homeowners wanting the cleanest possible result
This is the gold standard. All cables — including a code-compliant power solution — are routed completely inside the wall. Nothing is visible except the TV itself.
What Professional In-Wall Concealment Includes
- Dedicated electrical outlet installed directly behind the TV (no visible cords)
- Recessed media box for low-voltage connections
- CL2/CL3 rated HDMI, Ethernet, and coax routed through wall cavity
- NM-B (Romex) wiring for power — never a standard power cord
- Clean wall plates or brush covers at both entry and exit points
- All work meets NEC code requirements
Why This Requires Professional Installation
- Electrical work: Adding or extending an outlet requires a licensed electrician in most jurisdictions, including Georgia
- Fire blocks: Many walls have horizontal 2×4 fire blocks between studs that must be drilled through
- Insulation: Fishing cables through insulated walls requires specialized tools
- Permits: Some municipalities require permits for new electrical circuits
- Inspection: Professional work can be inspected and certified for home insurance compliance
Cost: $150–$350 professional installation (included with many wire concealment service packages)

Method 4: Furniture and Decorative Solutions
Best for: Situations where wall modification isn't possible
Sometimes the best solution doesn't involve the wall at all:
- Floating media console: Mounted below the TV, hides cables behind the unit ($100–$400)
- Cable-hiding art or panels: Decorative covers that swing open for access ($50–$150)
- Fabric cord covers: Fabric sleeves that blend with wall color ($8–$15)
- Strategic plant placement: Tall plants or decor positioned to hide cable runs (free if you have plants)
NEC Code Requirements You Need to Know
Electrical code compliance isn't optional — it affects your home insurance, resale value, and most importantly, safety. Here are the key requirements:
| Requirement | Code Reference | What It Means |
|---|---|---|
| No power cords in walls | NEC 400.12 | Standard power cables cannot be run inside wall cavities |
| In-wall power must use NM-B | NEC 334.10 | Only Romex-type wiring rated for permanent installation inside walls |
| Low-voltage cables must be rated | NEC 725.154 | HDMI, speaker wire, etc. must carry CL2 or CL3 rating for in-wall use |
| Outlet boxes required | NEC 314.16 | All electrical connections must be in approved junction/outlet boxes |
| GFCI protection near water | NEC 210.8 | Outlets within 6 feet of water sources need GFCI protection |
Georgia-specific note: Georgia follows the NEC with local amendments. Most counties in metro Atlanta require a permit for new electrical circuits. Our team handles all permitting when electrical work is needed.

Key insight: For full in-wall concealment, professional installation often costs less than DIY when you factor in tools (drywall saw, fish tape, voltage tester), materials, and the risk of mistakes. And pros guarantee code compliance.
Surface-Specific Considerations
Your wall type significantly affects which concealment methods work:
Drywall
All methods work on drywall. It's the easiest surface for cable concealment because you can cut openings and fish cables through the cavity. Most in-wall kits are designed specifically for drywall. See our drywall mounting services →
Brick and Stone
In-wall routing is not possible through solid masonry. Options include surface-mounted raceways (painted to match mortar color), channel cutting with a masonry saw (expensive, permanent), or routing cables through adjacent drywall sections. See our brick mounting services →
Fireplace Surrounds
Fireplace installations present unique challenges — heat considerations, masonry surfaces, and often longer cable runs. Professional concealment typically routes cables through the side of the fireplace chase or behind adjacent drywall. See our fireplace mounting services →
Concrete
Similar to brick — surface raceways are the primary option. Conduit can be surface-mounted and painted. In commercial settings, cables are often routed through ceiling spaces above the wall.
DIY vs. Professional: When to Call for Help
DIY Is Fine When:
- You're using cord covers or surface raceways only
- You're routing low-voltage cables through drywall with no fire blocks
- No electrical work is needed (outlet already behind TV location)
- You're comfortable cutting drywall and have basic tools
Hire a Professional When:
- You need a new outlet or outlet relocation (electrical work)
- Walls have fire blocks, insulation, or complex framing
- Mounting surface is brick, stone, tile, or concrete
- You want guaranteed code compliance and warranty coverage
- Multiple cable runs needed (soundbar, gaming consoles, etc.)
- You're in a rental and need minimal wall damage

Pro Tips for the Cleanest Possible Result
- Use the shortest cables possible. Excess cable length creates bulk inside the wall or behind the TV. Measure first, then buy exact lengths.
- Label every cable. Before routing anything through the wall, label both ends. You'll thank yourself later when troubleshooting.
- Leave a pull string. When routing cables through the wall, pull a nylon string alongside them. If you ever need to add or replace a cable, you can use the string to pull new cables through without opening the wall.
- Use 90-degree HDMI adapters. Standard HDMI cables stick straight out from the TV, increasing the gap between TV and wall. Right-angle adapters let the TV sit flush.
- Paint raceways before installing. If using surface-mounted covers, paint them the wall color before mounting. You'll get cleaner paint coverage and avoid tape lines.
- Consider wireless HDMI. For situations where running cables is impractical, wireless HDMI transmitters ($80–$150) eliminate the need for a physical HDMI run entirely. Latency is minimal for TV watching but may affect gaming.
Frequently Asked Questions
Is it against code to run TV wires through a wall?
Low-voltage cables (HDMI, Ethernet, coax) with CL2 or CL3 ratings can legally run through walls. However, standard power cords cannot — this violates NEC Article 400.12. You need either a UL-listed in-wall power kit or a dedicated outlet behind the TV.
What is the cheapest way to hide TV cords?
Adhesive cord covers start at $10–$15 and require no tools or wall modifications. They're the most budget-friendly option and work well for renters. For a more permanent solution, a basic in-wall pass-through kit costs $40–$60.
Can I hide TV wires in a rental apartment?
Yes — use adhesive cord covers or fabric cable sleeves that don't damage walls. Avoid any solution that requires cutting into drywall. Some renter-friendly TV mounts also include integrated cable channels. See our apartment mounting guide for more options.
How much does professional cable concealment cost?
Professional in-wall cable concealment typically costs $150–$350, which includes outlet installation, CL2-rated cable routing, and clean wall plates. This is often bundled with TV mounting service at a package discount.
Do I need an electrician to hide TV wires?
Only if you need electrical work — adding or moving an outlet requires a licensed electrician in Georgia and most states. For low-voltage cables only (HDMI, Ethernet), you don't need an electrician, but you do need CL2-rated cables and proper wall plates.
