How much does a whole-home renovation cost in New Brunswick?

A whole-home renovation in New Brunswick costs $40,000–$300,000+ depending on the scope, the size of the home, and the depth of work involved — a cosmetic refresh is a very different project from a comprehensive gut-to-studs renovation, and the price difference reflects that reality.

At the entry level, a cosmetic whole-home refresh — paint throughout, new flooring in all rooms, updated light fixtures, new interior doors and hardware, and refreshed bathroom and kitchen fixtures without moving plumbing — runs $50–$75 per square foot. For a typical 1,200–1,500 sq ft NB bungalow, that translates to $60,000–$112,000. This work transforms how a home looks and feels without touching its mechanical, electrical, or structural systems.

Step up to a comprehensive mid-range renovation — a full kitchen renovation with new cabinets, countertops, and appliances; full bathroom gut and rebuild; new flooring throughout; window replacements; upgraded insulation and vapour barrier; and electrical panel upgrade — and you're looking at $80–$150/sq ft. On a 1,500 sq ft home, that's $120,000–$225,000. This level of renovation addresses both cosmetic and functional deficiencies and typically delivers a meaningfully more comfortable, energy-efficient home at the end.

A full gut renovation — stripping an older NB home down to the studs, correcting structural issues, completely replacing electrical and plumbing systems, installing modern insulation and vapour barrier throughout, then rebuilding with premium finishes — runs $150–$250/sq ft. On a 1,500 sq ft home, that means $225,000–$375,000. This scope is most common with pre-1960 homes where the mechanical, structural, and envelope systems have reached end-of-life simultaneously.

What Drives Cost in an NB Whole-Home Renovation

The biggest cost variables are the age of the home and what's discovered once walls open. NB has a significant inventory of pre-1980 homes, particularly in Fredericton, Saint John, and smaller communities throughout the province. Renovating these homes almost always involves addressing knob-and-tube or aluminum wiring, galvanized or cast-iron plumbing, undersized electrical panels (60-amp services that need upgrading to 200-amp), and in pre-1990 homes, potentially asbestos-containing materials in floor tiles, pipe insulation, or ceiling texture. Professional asbestos abatement alone can run $3,000–$15,000 before any renovation work begins.

NB's climate adds another layer. A whole-home renovation in Maritime New Brunswick that doesn't address the building envelope — air sealing, proper insulation, updated vapour barrier, and HRV installation — is a missed opportunity. Homes that were built with 3.5 inches of fibreglass batt in the walls and R-20 in the attic are chronically cold in winter and humid in summer. Adding closed-cell spray foam on the rim joists, dense-pack cellulose in the walls, and upgrading the attic to R-60 will add $20,000–$40,000 to a whole-home renovation but typically reduces annual heating costs by 25–40% — a payback that matters given NB energy costs.

Timeline for a whole-home renovation on a typical NB home runs 4–8 months depending on scope. A cosmetic refresh might complete in 6–10 weeks. A comprehensive renovation of a 1,500 sq ft bungalow involving kitchen, bathrooms, windows, insulation, and flooring takes 4–6 months. A full gut renovation takes 6–12 months, particularly if heritage features are being preserved or structural corrections are involved.
