The basic idea
A mounted TV has two cables: an HDMI from your source devices (cable box, Apple TV, gaming console) and a power cord. Without concealment, both cables hang visible from the back of the TV down to your console.
In-wall concealment routes both cables INSIDE the wall through the stud cavity (the empty space between studs). At the TV height, we install a recessed power outlet — your TV plugs into the wall directly, no visible power cord. Below the TV at floor level, we install a low-voltage passthrough plate where the HDMI exits and connects to your source devices.
The result: a clean wall with two small flush plates and zero visible cables.
Why DIY is risky (legally and physically)
Standard HDMI and power cables are NOT rated for in-wall use. They lack the fire-resistant jacketing required by the National Electrical Code (NEC). Running them inside a wall is a code violation in every state including North Carolina.
More importantly: regular cables can become a fire hazard inside walls. If the cable jacket melts during a wall fire, it spreads flame and toxic smoke faster. UL-listed in-wall rated cables (CL2, CL3, or plenum-rated) prevent this.
A homeowner doing DIY concealment with off-the-shelf HDMI is technically violating NEC Article 800. If a fire investigator finds the wiring after a structure fire, your insurance company can deny the claim.
What we install (the right way)
- —UL-listed CL2 or CL3 rated in-wall HDMI cable, sized correctly for your run length
- —Recessed in-wall power outlet (UL-listed, NEC-compliant) at TV height — your TV plugs directly into the wall
- —Low-voltage passthrough plate at floor height — HDMI exits cleanly to source devices
- —Fish tape and proper bend radius technique — cables routed through stud bay without damage or kinks
- —Mortar-matched patch if any drilling is visible (rare — plates cover the holes)
When in-wall does not work
Solid masonry walls (brick, stone, concrete) have no stud cavity to fish through. We use surface raceways or external routing instead.
Walls with HVAC ducts, plumbing, or insulation in the path. We assess before drilling — about 5% of Charlotte homes have unsuitable wall paths and we recommend alternatives.
Steel-stud commercial walls (different fire-block requirements) — these need a different concealment approach.
How long does it take and what does it cost?
20 to 40 minutes for most Charlotte homes with standard 2x4 wood-stud drywall construction. Add 10-20 minutes for fire blocks, insulation, or unusual wall configurations.
In-wall concealment costs $40 as an add-on to any TV mount, OR is included free in our Pro Conceal ($189) and Full Cinema ($249) packages. No separate materials charge — UL-listed cables and recessed plates are included.
