Will a renovation increase my home insurance premiums in NB?

Most renovations will not increase your home insurance premiums in New Brunswick, and many improvements actually reduce your rates. However, you must notify your insurer about significant renovations to maintain proper coverage and avoid claim complications.

Renovations That Typically Lower Premiums

Insurance companies in NB often offer discounts for improvements that reduce risk. Roof replacements with modern materials can reduce premiums by 5-10%, especially if you upgrade from asphalt shingles to metal roofing or install impact-resistant shingles. Electrical panel upgrades from older fuse boxes or Federal Pioneer panels to modern breaker panels typically qualify for discounts since they reduce fire risk significantly.

Plumbing upgrades that replace old galvanized or polybutylene pipes with copper or PEX reduce water damage risk and may qualify for premium reductions. Installing a monitored security system, upgrading to impact-resistant windows, or adding a whole-home generator can also reduce premiums. In coastal NB communities, storm shutters or hurricane straps may qualify for wind damage discounts.

When Premiums May Increase

Adding square footage through additions or finishing a basement increases your home's replacement value, which means higher coverage limits and potentially higher premiums. However, the increase is usually modest — typically $2-5 per month for every $10,000 in added value. Converting a single-family home to a duplex or adding a rental suite changes your property classification and will increase premiums since rental properties carry higher liability risks.

Swimming pools, hot tubs, and trampolines increase liability exposure and typically add $50-200 annually to premiums. Home-based businesses may require additional coverage depending on the type of work and client traffic.

Critical Notification Requirements

You must notify your insurer before starting any renovation that increases your home's value by more than $5,000 or changes its use. This isn't optional — failing to notify can void your coverage. Most NB insurers require notification for kitchen and bathroom gut renovations, additions, basement finishing, major electrical or plumbing work, and structural modifications.

During major renovations, your home faces increased risks — theft of materials, contractor liability, fire from construction activities, and weather exposure if the building envelope is opened. Many insurers offer renovation coverage endorsements that protect against these specific risks for $100-300 annually.

Timing Your Notifications

Contact your insurer during the planning phase, not after work begins. Provide renovation details including scope, timeline, contractor information, and estimated completion value. Your insurer may require proof that contractors carry proper liability insurance and WorkSafeNB coverage. Some insurers inspect major renovations before and after completion.

If you're doing a gut renovation or major addition, consider increasing your coverage limits temporarily to account for materials stored on-site and the increased replacement cost during construction.

NB-Specific Considerations

Maritime climate improvements often qualify for discounts in NB. Upgrading insulation, installing proper vapour barriers, adding HRV systems, or improving basement waterproofing can reduce moisture-related claims and may qualify for premium reductions. Wind-resistant improvements are particularly valuable along the Bay of Fundy where storm damage is more common.

Heritage home renovations may require specialized coverage since replacement costs for heritage materials and craftsmanship are significantly higher than standard construction.

The key is communication — notify your insurer early, document improvements that reduce risk, and ensure your coverage keeps pace with your home's increased value. Most renovations either maintain current premiums or reduce them through risk-reduction discounts.
