The Detail Most Homeowners Skip Before the First Nail Goes In
Alberta homeowners are an industrious bunch. Every spring and summer, renovation projects kick into full gear across Edmonton and the rest of the province, from kitchen and bathroom overhauls to full additions, basement developments, and structural upgrades. The planning that goes into these projects is extensive, including design meetings, contractor quotes, material selections, and permit applications.
Then there’s the one step that gets skipped almost every time: calling the insurance broker.
It’s easy to see why. When you’re juggling contractors, timelines, and budgets, updating your insurance policy doesn’t feel urgent. Not talking to your insurance broker can put your home at risk because a major renovation can meaningfully change your coverage situation from the moment work begins. In some cases, your renovation can even create gaps that leave you without protection if something goes wrong mid-project.
The good news is that understanding home renovation insurance doesn’t require a law degree or an industry background. A few straightforward steps, taken before work begins, make an enormous difference.
Why Major Renovations Change Your Insurance Picture
Your standard home insurance policy was written based on your home as it existed when you took out coverage. The insurer assessed the rebuild value, the square footage, the materials, and the risk profile of the property at that specific point in time. When you start significantly changing the home, some of those assumptions no longer hold.
The following are a few examples of how a renovation can affect your coverage:
- Rebuild value changes. A new kitchen addition or a finished basement increases the replacement cost of your home. If your coverage limit doesn’t keep pace, you could be underinsured when you need to file a claim, even years later.
- Vacancy provisions may apply. If your home becomes partially or fully unoccupied during an extensive renovation, some policies reduce coverage or impose restrictions after a set number of days. This is more common than most homeowners realize.
- Coverage for materials and fixtures. Building materials left on-site, custom cabinetry waiting to be installed, new appliances sitting in your garage—these items may or may not be covered under your existing policy, depending on its terms.
- Increased liability exposure. A renovation site is a different environment from a finished home. Workers, subcontractors, delivery people, and inspectors are on and around your property. If someone is injured, questions about liability can get complicated quickly.
None of this is meant to be alarming. It’s simply worth knowing before work starts, rather than discovering it during a claim.
When to Notify Your Insurer of Your Home Renovation Plans
A good rule of thumb is to notify your broker before any significant project begins. “Significant” generally means anything that changes the structure of the home, increases its square footage, adds substantial value, or involves contractors working on-site for an extended period.
Projects that almost always warrant a conversation with your broker include:
- Home additions or extensions
- Kitchen or bathroom gut renovations
- Basement developments or finishing
- Roof replacements
- Structural changes (load-bearing wall removal, for example)
- Garage additions or conversions
- Secondary suite installations
Smaller cosmetic updates, such as painting, flooring swaps, and fixture replacements, typically don’t require a policy change, but it’s always worth a quick check if you’re unsure.
At Cornerstone, we take renovation calls all the time, and we’d always rather have a five-minute conversation before work starts than a difficult one after something goes wrong. As an independent brokerage, we work for you, not the insurance companies. If your current policy isn’t the right fit for a major project, we’ll shop the market and find one that is. Reach out to us before your project gets underway, and we’ll walk through exactly what your current coverage looks like and whether any adjustments make sense.
Contractor Insurance: What to Verify (and Why It Matters)
Hiring a contractor means bringing another party’s risks onto your property. A licensed, reputable contractor carries their own insurance and verifying that coverage before they set foot on your job site is one of the most important steps you can take.
Here’s what to ask for before work begins:
General Liability Insurance. This covers property damage or bodily injury that occurs as a result of the contractor’s work. If their crew accidentally damages your neighbour’s fence, or if a subcontractor causes water damage to your home, their liability policy is the first line of protection. Ask for a certificate of insurance and confirm the coverage limits are reasonable for the scope of your project.
Workers’ Compensation Coverage. In Alberta, most employers with workers are required to have Workers’ Compensation Board (WCB) coverage. If a worker is injured on your property and the contractor doesn’t carry proper WCB coverage, you could face unexpected liability. Ask to see their WCB clearance letter before work begins.
Builder’s Risk or Course of Construction Insurance. For larger projects—particularly full additions or major structural work—ask whether the contractor carries course of construction insurance, or whether you need to arrange it separately. This coverage protects the project itself while it’s being built: the structure, materials, and fixtures in progress. Some homeowners’ policies extend to cover renovation projects; many do not, or they cover only a portion of the work.
A reputable contractor will have no hesitation providing these documents. If they’re reluctant or can’t produce them, that’s important information for you to consider.
How Significant Renovations Affect Your Policy Long-Term
Once the renovation is complete, there’s one more step that homeowners frequently miss: updating the policy to reflect the improved property.
This matters for a vital reason. If your kitchen addition costs $150,000 to build and you never updated your coverage limit, your policy is still based on the pre-addition value of your home. In the event of a total loss, you’d be rebuilding a more valuable home than your insurer has on file, and you’d be covering the difference out of pocket.
Some renovations also affect the risk profile of the home in positive ways. Upgraded electrical panels, new plumbing, high-quality roofing materials, and modern HVAC systems can actually reduce your premiums in some cases, because they lower the risk of the incidents insurers are protecting against. These improvements are worth asking your broker about.
Underinsurance is one of the most common issues Alberta homeowners encounter after a major loss, and brokers see it regularly after renovations. The Insurance Bureau of Canada is a helpful resource if you want to learn more about how home insurance works in Canada. Either way, a post-renovation coverage review is a straightforward way to make sure your policy reflects everything you’ve invested.
A Simple Pre-Renovation Insurance Checklist
To give you peace of mind before your renovation begins, run through these steps:
- Call your broker. Let them know what you’re planning, when work starts, and how long it’s expected to take. They’ll advise on any policy adjustments.
- Confirm your current coverage limits. Make sure your dwelling limit reflects the current rebuild value of your home before you add more.
- Ask about vacancy provisions. If your renovation requires you to move out temporarily, ask your broker how your policy handles vacant or partially vacant homes.
- Verify contractor documentation. Request a certificate of insurance showing general liability coverage and a WCB clearance letter before signing any contract.
- Ask about course of construction coverage. Confirm whether your policy or the contractor’s policy covers materials and the structure in progress.
- Update your policy when the project is complete. Report the finished renovation to your broker so your coverage limit reflects your home’s new rebuild value. A completed renovation is also the perfect trigger for an annual policy review. At Cornerstone, we do this with all our clients to make sure coverage keeps pace with your life changes.
