How does a kitchen renovation affect home insurance in NB?

A kitchen renovation can affect your New Brunswick home insurance in several ways — your dwelling coverage limit may need to increase to reflect the higher replacement cost, and unpermitted work could give your insurer grounds to deny a future claim. It is essential to notify your insurance provider before or during a major kitchen renovation to keep your coverage valid.

The most immediate impact is on your dwelling replacement cost. If you invest $25,000 to $75,000 in a kitchen renovation with new custom cabinets, quartz countertops, and upgraded appliances, the cost to rebuild your home in the event of a fire or total loss has increased accordingly. If your policy still reflects pre-renovation replacement values, you could be underinsured. Contact your insurer to update your dwelling coverage — the premium increase for a mid-range kitchen renovation is typically modest, often $50 to $150 per year, but the protection is critical.

Permits and code compliance directly affect your insurance standing. In New Brunswick, electrical changes, plumbing modifications, and structural work all require permits and inspections. If you renovate without proper permits and a claim later arises from that work — an electrical fire from improperly wired circuits, water damage from faulty plumbing — your insurer may deny the claim entirely or reduce your payout. This is especially relevant in older NB homes where kitchen renovations often uncover knob-and-tube wiring, galvanized plumbing, or undersized 60-amp electrical panels that need upgrading. Get permits for all work that requires them, keep copies of inspection approvals, and store them with your insurance documents.

During the Renovation

Your home faces elevated risk during active construction. Exposed wiring, disconnected plumbing, construction debris, and workers coming and going all increase the likelihood of damage or injury. Most NB homeowner insurance policies continue to cover your home during renovations, but some have exclusions for homes that are unoccupied during construction or for damage directly caused by renovation work. Review your policy before demolition begins, and inform your insurer about the scope and timeline of the project.

Make sure your contractor carries their own liability insurance and WorkSafeNB coverage. If an uninsured worker is injured in your home, you could be liable. Ask for proof of insurance before work begins — reputable NB kitchen renovation contractors will provide this without hesitation. Your insurer may also want to know who is performing the work and whether they are properly licensed and insured.

After the renovation is complete, document everything with photographs and keep receipts for materials, appliances, and labour. This documentation speeds up any future claim and ensures you receive full replacement value. Update your home inventory list to include new appliances, fixtures, and finishes with their purchase prices.

One positive effect: a well-renovated kitchen with updated electrical, modern appliances, and proper ventilation can actually reduce certain risk factors that insurers consider, particularly if you have upgraded from an old 60-amp panel to 200-amp service or replaced galvanized plumbing with copper or PEX.
