How much does smoke detector hardwired cost in New Brunswick?

Hardwired smoke detector installation in New Brunswick typically costs $150-$300 per detector, including the unit and professional installation. For a full-home system with interconnected alarms, expect $800-$2,000 depending on your home's size and wiring complexity.

Breaking down the costs: The smoke detectors themselves run $40-$80 each for quality hardwired units with battery backup. Basic ionization models start around $40, while photoelectric or dual-sensor units with 10-year sealed batteries cost $60-$80. Installation labor adds $100-$220 per detector, varying based on accessibility and whether new wiring runs are needed.

New Brunswick code requirements significantly impact your project scope. Under the National Building Code 2020 (adopted in NB), smoke alarms must be hardwired and interconnected in all bedrooms, outside sleeping areas, and on every level including basements. This means when one alarm sounds, they all sound throughout the house. Carbon monoxide detectors are also required near sleeping areas if you have fuel-burning appliances or an attached garage.

The electrical work must be performed by a licensed electrical contractor — homeowners cannot legally install hardwired smoke detectors themselves in New Brunswick. Your contractor needs to obtain an electrical wiring permit from NB Power (1-800-615-0522) before starting work, and the installation requires a final inspection by Technical Inspection Services (TIS).

Factors affecting your total cost include your home's age and current wiring. Newer homes often have dedicated smoke detector circuits, making installation straightforward. Older homes may need new 14-gauge wire runs between detector locations, adding $200-$400 per new circuit. Two-story homes typically need 6-8 detectors minimum, while bungalows might only need 3-4.

Your next step: Contact a licensed electrical contractor through our New Brunswick Construction Network directory for a site assessment. They'll evaluate your current wiring, determine how many detectors you need for code compliance, and provide an accurate quote based on your home's specific layout and electrical system.
