How much do contractors charge for basement finishing high in New Brunswick?

Basement finishing in New Brunswick typically ranges from $45-$85 per square foot for high-end work, putting a 1,000 sq ft basement between $45,000-$85,000. This reflects premium materials, custom millwork, and detailed craftsmanship that transforms your basement into true living space.

High-end basement finishing in the New Brunswick market includes engineered hardwood or luxury vinyl plank flooring ($8-$15/sq ft), custom built-ins and entertainment centers, coffered or tray ceilings, high-quality trim work, and premium fixtures throughout. Many contractors also include a full bathroom with tile work ($15,000-$25,000) and a wet bar or kitchenette ($8,000-$20,000) in their high-end packages.

The National Building Code 2020 (mandatory in NB as of May 1, 2025) requires egress windows in any bedroom, minimum 6'5" ceiling height, and proper fire separation if creating a secondary suite. Before starting any basement finishing, get a radon test — New Brunswick has some of Canada's highest radon levels, with 1 in 4 homes exceeding Health Canada guidelines. If levels are high, factor in $2,500-$5,000 for a mitigation system.

Electrical and plumbing rough-in must be done by licensed contractors with proper permits. Contact NB Power at 1-800-615-0522 for electrical wiring permits, and TIS at 1-888-659-3222 for plumbing permits and inspections. Your municipality or Regional Service Commission will also require a building permit for the renovation.

Factors pushing costs toward the high end include moisture remediation (common in NB's clay soils), structural modifications, HVAC extensions, and the complexity of working around existing mechanicals. Spring flooding is a concern in areas like Fredericton and the Saint John River valley — ensure proper waterproofing and drainage before finishing.

Timeline for high-end work runs 8-12 weeks once permits are secured, but skilled trades are in high demand across New Brunswick. Book your contractor well in advance, especially for work starting in spring when everyone wants to tackle indoor projects after winter.
