Do I Need Pre-Wiring for a New Home or Renovation?

Pre-wiring is the cheapest time to add cables for TVs, speakers, Wi-Fi and cameras. Learn what to run before the walls close.

What is pre-wiring?

Pre-wiring means running cables for technology while the walls are open, before insulation and drywall.

Why it matters

Adding cable after drywall is possible but more work. Pre-wire is the easiest way to get a clean, reliable result.

What to run

Common pre-wire runs include:

  • Network cable to access point locations
  • Network and power at TV locations
  • Speaker wire for ceilings and walls
  • Camera and doorbell cabling
  • Cable to a central equipment closet
  • Keypad and control wiring

Plan with your builder

Share plans with your technician early so wiring lands where the TVs, speakers and devices will live. We coordinate with builders, electricians and architects.

Already finished?
