What home insurance companies actually check about your tradespeople

Most homeowners do not give their insurance policy a second thought when they hire a contractor. In the great majority of cases, that is perfectly fine and nothing ever comes of it. But there are specific situations where the contractor you choose, and how they work, can create a genuine insurance complication, and they are worth understanding before rather than after.

This is a calm walk through what your insurer actually cares about when work is done on your home. The goal is not to make you anxious. It is to make sure a problem that is easy to avoid does not catch you out.

What your insurer wants to know about renovation work

Insurers treat a major renovation differently from day-to-day living in your home, and they would like to know about it.

Above a certain dollar value, which varies from insurer to insurer, a significant renovation should be disclosed to your insurance company. Depending on the policy, that might mean adding a renovation rider or arranging separate builder's risk coverage for the duration of the work. There are also rules about vacancy: if a renovation means the house sits empty for an extended period, standard policies can treat it as a vacant home, which changes your coverage in ways you do not want to discover after a burst pipe.

The fix is simple and it is the same throughout this article. Tell your insurer before the work starts, not after.

The unlicensed contractor problem, and why it matters for your policy

This is the one that turns a saving into a disaster.

If something goes wrong, a fire, water damage, a structural failure, and it traces back to work done by someone who was not licensed to do that work, your insurer may deny the claim or reduce the payout. This is not a far-fetched scenario. It happens, and it happens most often with the two trades where it matters most: electrical and gas.

An unlicensed person doing licensed electrical or gas work is not just a quality gamble. They are potentially voiding your ability to claim if their work causes the damage. The few hundred dollars saved by hiring outside the rules can sit in front of a five or six figure loss your insurer is no longer willing to cover.

Contractor insurance versus your insurance

There are two layers of protection here, and you want the first one to do the work.

A contractor who carries their own liability insurance is your first line of defence if they cause damage to your home. Their policy responds, not yours. If they have no insurance and they flood your kitchen or start a fire, that claim lands on your policy, with your deductible and your future premiums, assuming it is even covered.

This is exactly why asking for a certificate of insurance is not fussiness. It is you confirming that the first layer exists, so a contractor's mistake stays the contractor's problem and not yours.

What to tell your insurer before a major project

A single phone call before the work starts saves most of the trouble in this article.

Call your insurer and ask three things. Does this project need to be disclosed or noted on my policy? Do I need additional coverage while construction is underway? And what documentation should I keep in case I ever need to make a claim? None of this takes long, and it puts you on record as having done the right thing, which matters if anything ever goes wrong.

After the work is done: updating your policy

There is one more step people forget once the dust settles.

A finished basement, an addition, or a major renovation increases what it would cost to rebuild your home. If your coverage still reflects the house as it was before, you are now underinsured, and you may not find that out until you are trying to claim for a total loss and the numbers fall short. When a project meaningfully adds value or square footage, ask your insurer to reassess your rebuild coverage so the policy keeps up with the house.

Insurance is the quiet backstop behind every renovation, and the contractor you choose is part of whether it holds. This is one of the reasons we verify insurance as part of vetting: every tradesperson listed with us has produced a current certificate, with the expiry on file. It does not replace the call to your own insurer, but it does mean the person in your home is carrying the coverage that keeps their mistakes off your policy.
