Should I install smart switches throughout my NB home?

Smart switches can be a great upgrade for New Brunswick homeowners, but there are a few important technical and practical factors to consider before committing to a whole-home installation.

The biggest technical hurdle is the neutral wire requirement. Most modern smart switches (Lutron Caseta, Leviton Decora Smart, TP-Link Kasa, etc.) require a neutral wire at the switch box to complete the circuit. Older New Brunswick homes — especially those built before the 1980s — often have switch loops without a neutral wire present. Before purchasing anything, have a licensed electrician check your switch boxes. If neutrals are missing, you have two options: run new wiring (adds cost) or choose a no-neutral smart switch like the Lutron Caseta line, which uses a different communication protocol and works reliably without one.

Three-way and four-way switch locations (staircases, hallways, large rooms with multiple switches) add complexity. Smart three-way setups typically require a smart switch at one location and a compatible "accessory" switch at the other — you can't just swap in two regular smart switches and expect them to work together. This is worth planning carefully before you buy a houseful of switches.

Cost and Practicality in NB

Smart switches themselves run $40–$80 per switch for quality brands, and installation by a licensed electrician typically costs $75–$150 per switch depending on complexity. For a whole-home installation of 20–30 switches, you're looking at $2,300–$6,900 all-in. That said, replacing switches like-for-like is one of the few electrical tasks homeowners can legally do themselves in New Brunswick (with power off), which can reduce labour costs significantly if you're comfortable with basic wiring.

From a New Brunswick climate perspective, smart switches pair especially well with automated exterior lighting — useful during our long winters when daylight hours are short and ice storms can leave you navigating a dark home. Scheduling exterior lights, integrating with a smart home hub, and controlling lighting remotely during power restoration after an NB ice storm are all practical benefits here.

When to Call a Pro

If your home has knob and tube wiring or aluminum wiring, do not attempt any switch replacements yourself. These systems require a licensed electrician to assess before any modifications. Similarly, if you're unsure whether a neutral wire is present, an electrician can check quickly and advise on your best options. Most switch replacements don't require a TSANB permit, but if new wiring is needed to add neutral conductors, that work would require a permit and inspection.

The bottom line: Smart switches are worth it for most NB homeowners, but do a room-by-room assessment of your wiring first. Start with a few high-traffic areas (kitchen, living room, front entrance) before committing to the whole home.
