What is the average cost per square foot for home renovations in New Brunswick?

Whole-home renovation costs in New Brunswick range from $50 to $250 per square foot, depending on scope, age of the home, and quality of finishes — a range wide enough that the answer requires knowing what kind of work you're actually doing.

At the lower end of that range, a cosmetic whole-home refresh — new paint throughout, updated flooring, refreshed lighting and fixtures — on a 1,500 sq ft home runs roughly $50–$75/sq ft, or $40,000–$75,000 total. This type of work changes how a home looks and feels without touching the bones. Step up to a mid-range comprehensive renovation — kitchen, bathrooms, flooring, windows, and some insulation and electrical upgrades — and you're looking at $80–$150/sq ft, or $100,000–$200,000 for that same 1,500 sq ft home. At the top end, a full gut-to-studs renovation of an older NB home — the kind that involves new wiring, new plumbing, structural corrections, envelope upgrades, and premium finishes throughout — will run $150–$250/sq ft.

On a trade-by-trade basis, the per-square-foot cost varies dramatically by what's being done. Flooring installation (laminate or LVP) runs $5–$12/sq ft installed. Basement finishing starts around $30–$50/sq ft for basic work and climbs to $60–$100/sq ft with a full bathroom, bedroom, and quality finishes. Additions (new floor area added to the home) cost $250–$400/sq ft for single-storey construction. Kitchen renovations don't price cleanly by square foot — they run $15,000–$100,000+ depending on the level of work, since the cost is driven by cabinetry, appliances, countertops, and trade work rather than floor area.

Why NB Homes Often Cost More Per Square Foot to Renovate Than They Appear

New Brunswick's older housing stock is one of the key cost variables that province-wide averages rarely capture. A cosmetic renovation on a 1980s Fredericton bungalow often turns into a mid-range renovation once the walls are open — knob-and-tube wiring that must be replaced, undersized plumbing that can't support a modern bathroom, asbestos-containing materials in floor tiles or insulation, and framing that isn't quite to modern standards. In a home built after 2000, you're mostly spending on materials and labour. In a pre-1980 NB home, budget 20–25% contingency because the surprises are practically guaranteed.

NB's climate also affects per-square-foot costs. Proper insulation upgrades (closed-cell spray foam on foundation walls, dense-pack cellulose in attic and walls) are not optional in a Maritime climate with 100+ freeze-thaw cycles annually and humidity swings of 30–50% between seasons. Cutting those line items out of a renovation budget to reduce the cost-per-foot is a false economy — you'll spend the money later on heating bills, moisture damage, and mould remediation.

As a practical planning tool, the $50–$250/sq ft range tells you the outer limits. What matters is building a detailed scope with your contractor, getting 3+ quotes in writing, and adding a proper contingency. Always get current quotes for your specific project — material costs fluctuate and NB renovation pricing varies 20–40% between contractors for identical scope.
