How much does a complete gut renovation cost in New Brunswick in 2026?

A complete gut renovation in New Brunswick typically costs $150-$250 per square foot in 2026, meaning a 1,500 sq ft home would run $225,000-$375,000 depending on finishes and structural complexity.

Gut renovations involve stripping the home down to the structural frame and rebuilding everything — electrical, plumbing, insulation, drywall, flooring, kitchen, bathrooms, windows, and often HVAC systems. The wide price range reflects the dramatic difference between basic builder-grade finishes versus premium materials, as well as the extent of structural work required in older NB homes.

Budget Breakdown for a Typical 1,500 Sq Ft NB Home:

• Basic gut renovation ($150-$180/sq ft): New electrical panel and wiring, updated plumbing rough-in, spray foam insulation, drywall throughout, laminate flooring, basic kitchen with stock cabinets, standard bathroom fixtures, builder-grade windows, and basic lighting. Total: $225,000-$270,000.


• Mid-range gut renovation ($180-$220/sq ft): Everything above plus hardwood or luxury vinyl flooring, semi-custom kitchen cabinets, quartz countertops, tile backsplash, upgraded bathroom with tile shower, better windows, pot lights throughout, and quality interior doors. Total: $270,000-$330,000.


• High-end gut renovation ($220-$250/sq ft): Premium finishes including custom cabinetry, natural stone countertops, hardwood flooring throughout, luxury bathroom fixtures, high-efficiency windows, smart home integration, crown moulding, and designer lighting. Total: $330,000-$375,000.

New Brunswick's Maritime climate significantly impacts gut renovation costs. Older NB homes often require extensive moisture remediation, foundation repairs, and envelope upgrades that aren't immediately visible. Spring snowmelt frequently reveals foundation issues, while decades of freeze-thaw cycles may have compromised the building envelope. Budget an additional $15,000-$30,000 for unexpected structural repairs, foundation waterproofing, or envelope improvements in pre-1980 homes.

Mechanical systems represent a major cost component in NB gut renovations. Complete electrical rewiring with a new 200-amp panel costs $8,000-$15,000. Full plumbing replacement including new supply lines, drain lines, and fixtures runs $12,000-$25,000. HVAC system replacement or installation adds $8,000-$20,000, with heat pumps becoming increasingly popular for their efficiency in NB's climate.

The permitting and professional requirements add to the total cost but are essential for safety and resale value. Structural modifications require engineering assessments ($1,500-$3,000). All electrical and plumbing work must be performed by TSANB-licensed professionals and inspected. Building permits for gut renovations typically cost $2,000-$5,000 depending on your municipality.

Timeline expectations for gut renovations in NB run 4-8 months, with exterior work scheduled during the May-October construction season. Starting demolition in late fall allows interior work to proceed through winter, with exterior envelope work resuming in spring. This timing helps manage costs and ensures weather-sensitive work happens during optimal conditions.

Essential contingency planning is critical for gut renovations. Budget 20-25% contingency for older NB homes where hidden issues are common — knob-and-tube wiring, galvanized plumbing, asbestos insulation, or structural problems masked by previous renovations. A $300,000 gut renovation should have a $60,000-$75,000 contingency fund.

Financing considerations matter significantly at this investment level. Many homeowners use home equity lines of credit, refinancing, or construction loans to fund gut renovations. The improved home value typically justifies the investment in NB's strong real estate market, but cash flow management during the 6+ month project timeline requires careful planning.
