The Problem
Homeowners buy a Lutron Caseta or a smart dimmer, open the switch box, and find only two wires — no neutral. The smart switch won't work without it. This is extremely common in homes built before the mid-1980s across the DC Metro area.
Why the Neutral Wire Matters
Smart switches need a small amount of constant power to stay connected to Wi-Fi and respond to app commands. The neutral wire provides that return path. Without it, the switch either won't turn on or will flicker and behave unpredictably.
The Fix
We run a neutral wire from the nearest junction box or circuit to the switch box. It's a clean job — no drywall damage in most cases. Once the neutral is in place, the smart switch installs normally and works perfectly from day one.
When to Call an Electrician
If you open your switch box and don't see a white (neutral) wire bundled in the back, call us before buying smart switches. We'll assess your wiring and let you know the best path forward — no charge for the assessment.
