How much does a basement renovation cost in New Brunswick?
A basic basement finishing in NB typically costs $20,000-$40,000. Budget options (one open room, basic flooring, paint) start around $15,000-$20,000. Full renovations with a bathroom, bedroom, and custom finishes run $50,000-$80,000+. Underpinning adds $30,000-$80,000. NB labour rates are generally lower than major Canadian cities.
Do I need a permit for a basement renovation in NB?
You need permits for framing new walls, electrical wiring, plumbing rough-ins, egress window installation, and structural changes like underpinning. Adding a basement bedroom requires a code-compliant egress window. Cosmetic updates like painting or replacing flooring typically don't need permits. Check with your local building inspection office.
How long does a basement renovation take?
A typical basement finishing in NB takes 6-10 weeks. Simple open-concept finishes (framing, drywall, flooring, paint) can be done in 4-6 weeks. Complex renovations with bathrooms, bedrooms, and egress windows may take 10-14 weeks. Waterproofing or foundation repair should be completed first and adds 1-3 weeks.
Is basement waterproofing necessary in New Brunswick?
Waterproofing is strongly recommended before finishing any NB basement. Heavy Maritime rainfall, spring snowmelt, and high water tables in many areas make moisture a serious concern. Interior waterproofing with a sump pump typically costs $3,000-$8,000. Exterior waterproofing with membrane and weeping tile runs $8,000-$15,000. Addressing moisture upfront prevents costly damage later.
