The term “Retrofit” means Installing or providing a component or feature in a home that was not fitted, wired or installed during the original construction phases.
Retrofitting a home with wires for home automation technology can become expensive.
For example, when interior walls are down during a new construction Pre-wire, the charge to run a single speaker wire is $80.00.
