What renovation tasks always require a licensed contractor in NB?

In New Brunswick, any electrical work beyond simple fixture swaps, all plumbing rough-in or modifications, gas appliance installation, structural modifications, and asbestos abatement must be performed by licensed professionals. This isn't just best practice — it's provincial law enforced by TSANB (Technical Safety Authority of New Brunswick) and WorkSafeNB.

Electrical work requiring a licensed electrician includes installing new circuits, upgrading electrical panels, adding outlets or switches, wiring for appliances, and any work that involves opening electrical boxes or running new wire. Even something as simple as installing a ceiling fan on a new circuit requires TSANB-licensed electrical work and inspection. The only electrical work homeowners can legally do is swapping light fixtures on existing circuits (with the breaker turned off) and plugging in appliances.

All plumbing modifications require a licensed plumber in NB. This includes rough-in plumbing for new fixtures, moving water lines, installing water heaters, adding bathroom or kitchen plumbing, and any drain modifications. Homeowners can replace faucets, toilet seats, and showerheads on existing connections, but installing a new toilet, moving plumbing lines, or adding a basement bathroom requires professional installation and TSANB inspection.

Gas work is strictly professional-only in New Brunswick. Installing gas appliances, running gas lines, connecting gas fireplaces, and any work involving natural gas or propane requires a TSANB-licensed gas fitter. This includes seemingly simple tasks like hooking up a gas range or connecting a BBQ to a permanent gas line.

Structural modifications always require professional assessment and often professional installation. Removing or altering load-bearing walls, installing support beams, foundation work, and major framing modifications need an engineer's assessment and licensed contractor installation. Even determining whether a wall is load-bearing requires professional evaluation — guessing wrong can cause catastrophic structural failure.

Asbestos abatement is legally required to be performed by certified professionals in NB homes built before 1990. This includes removing asbestos-containing materials like floor tiles, insulation, texture coatings, and pipe wrap. Disturbing asbestos without proper containment and disposal creates serious health hazards and legal liability.

Roofing on multi-storey homes should be left to professionals due to fall risk and the specialized knowledge required for proper flashing, ventilation, and ice-and-water shield installation in NB's demanding climate. While not legally required to be professional-only, the safety risk makes it a practical necessity.

The consequences of skipping licensed professionals for these tasks are severe in New Brunswick. Insurance companies can deny claims for damage caused by unlicensed work. Home sales can be complicated if unpermitted electrical, plumbing, or structural work is discovered during inspection. TSANB can require expensive tear-out and re-do of work that wasn't properly inspected. Most importantly, improper electrical, gas, or structural work creates genuine safety hazards for your family.

Before hiring any contractor for these specialized tasks, verify their TSANB licensing for their specific trade and confirm they carry WorkSafeNB coverage. A legitimate contractor will readily provide both. If they can't, find someone else — the few hundred dollars you might save isn't worth the thousands in potential liability and safety risks.
