Renovations: When to Notify Your Home Insurer
Report the nature, cost and duration of the work to your insurer, especially if the home will be unoccupied during construction.
In this article
A renovation project transforms the house, and it also changes the risk the insurer agreed to cover. The contract therefore requires you to notify the insurer before the first hammer swing. Three subjects structure the call. First, declaring the work: nature, cost and duration. An undeclared transformation can compromise a claim, even one unrelated to the site. Second, occupancy: a home left unoccupied during the major phase triggers restrictions beyond a set number of days, which a notice and a simple arrangement settle. Third, value, the point most often forgotten. The work raises the reconstruction cost, and the insured amount must follow the moment the site closes, or you risk underinsurance and the coinsurance clause. Checking the contractor, meaning licence and liability insurance, completes the file. This article puts these calls in the right order, with the precise questions to ask and the temporary riders, which cost a few dozen dollars.
Declare the worksite before the first hammer swing
A worksite changes the risk the insurer priced: stored materials, workers, opened systems, value in transformation. The contract requires you to declare significant work (nature, cost, duration) before it starts, and the penalty for silence is broad. An undeclared transformation can compromise a claim, even one with no direct link to the work. The boundary is drawn in broad strokes. Paint and routine repairs need no call. An extension, kitchen, bathroom, roof, or electrical or heating system should be declared. When in doubt, call: five minutes is enough to document your good faith. The insurer answers with a confirmation, sometimes a temporary worksite rider. File it with the renovation records.
Settle the occupancy question
Major work often empties the dwelling, and vacancy triggers its own clauses. Beyond a number of days set in the contract, often thirty, some coverage narrows, water damage first, if the insurer has not been notified. Negotiate the fix in advance: a vacancy notice with an arrangement, either regular documented visits or a specific rider for the duration of the worksite, at modest cost. Winter adds seasonal obligations, such as keeping the heat on or shutting off the water supply, since a frozen pipe in an empty house can leak for weeks. Document your visits with time-stamped photos, because the owner has to prove the conditions were met. Managed vacancy is an administrative detail. Vacancy discovered at the time of a loss is a ground for denial.
Vet the contractor and frame the contract
Vetting the contractor protects your insurance as much as your worksite. Check the licence in the public register and ask for a certificate of liability insurance. Damage caused by an uninsured contractor climbs back toward your policy, with the recourse complications that follow. The written contract should specify responsibilities: who insures what during the work, the stored materials, and damage to existing structures. Confirm the required permits too, since a non-compliant worksite complicates claims and resale. These precautions follow the same principle as the declaration: every grey zone cleared before the worksite is a dispute avoided afterward. Store the complete file (licence, certificate, contract, permits) with your insurance documents. It will help if the worksite goes wrong.
Revise the insured amount when the work ends
Once the worksite closes, the house costs more to rebuild. The extension, the kitchen and the new systems add to the reconstruction value, and the insured amount must follow. Otherwise the improved house is underinsured the day the work ends, with the coinsurance clauses' consequences on any partial loss. Call the insurer at the end of the work, with the real cost in hand, to update the contract. The insurer's valuation tool recalculates as needed. This is the mandatory counterpart to the first call, and the more forgotten of the two. The opening declaration protected the worksite, the closing revision protects the transformed house. Keep the work's invoice on file too: it documents the adjusted cost base for tax purposes if you sell later.
Quebec scenario
A couple in Chambly plans a kitchen extension: $70,000, an eight-week worksite and three weeks at the parents' place during the major phase. The contractor is chosen, the permit issued, and nobody has thought about the insurer. Their broker catches the oversight in time and works through the situation. The nature, cost and duration of the work must be declared before it starts, because a worksite changes the risk and an undeclared transformation can compromise a claim. Vacancy during the major phase needs its own notice, since most policies restrict coverage when a home sits unoccupied beyond a set number of days. A planned daily visit settles the point. She also checks the contractor's liability insurance and licence, so the couple's coverage does not have to stand in for the builder's. Finally, the most common oversight: after the work, the home's reconstruction value will have risen by $70,000, and the insured amount must follow. Otherwise the couple would be underinsured the day the worksite closes. Two phone calls and a temporary rider at $60 are enough, and the project goes ahead without a blind spot.
