Water damage and home insurance: Covered or not?

Homeowner or renter?

Coverage varies depending on your situation. Even if you’re a renter, certain types of damage may affect you.

An example? You live on the ground floor and backed-up water reaches a neighbouring unit. You could be held liable and have to file a claim under your personal liability insurance. That’s why it’s important to fully understand what your home insurance coverage includes, and when to contact your insurer or insurance agent. 

Damage covered by a basic policy

Some incidents related to plumbing fixtures are generally covered by a standard home insurance policy. Still, always verify—contracts vary from one insurer to another.

Damage caused by plumbing fixtures

Your water heater leaks and damages the floating floor in your basement:

• Covered under the basic policy

The water supply line to your ice maker leaks and water damages a wall and the bottom of your cabinets:

• Covered under the basic policy

In these situations, your insurance covers the cost of repairing the water damage—but not the appliance itself.

Damage requiring additional coverage

These protections must have been added to your policy at the time of purchase. Even so-called all-risk policies don’t automatically include this type of coverage.

Damage caused by a burst drinking water line

The interior water line in your home breaks, and water floods your basement:

• Covered if you have the “Water Service Line Break” endorsement

Damage caused by water infiltration

In spring, melting snow water enters your basement through windows or window wells:

Covered if you have the “Water Damage – Ground Water and Sewer” endorsement

Water enters through your roof during a heavy fall rainstorm:

• Covered if you have the “Water Damage – Above-Ground Water” endorsement

Damage caused by sewer backup

Your neighbourhood experiences heavy rainfall and the sewers back up:

• Covered if you have the “Water Damage – Ground Water and Sewer” endorsement

Damage related to river overflow

River levels rise due to an ice jam. Water reaches your property and then enters your home:

Covered if you added flood protection and overflow protection. Not offered by all insurers. Eligibility conditions may apply.

In certain flood situations, Quebec’s Ministry of Public Security disaster assistance program may also provide financial support.

What your insurance doesn’t always tell you

Endorsements or additional protections for water damage come with specific coverage limits. For example: $10,000 to cover all costs related to water damage. Pay close attention to this amount—it differs from your overall insurance amount. And don’t forget: when filing a claim, the deductible listed in your policy applies.

It may be helpful to reassess your coverage if your home is located in a high-risk area.

Have you experienced water damage? Professional cleanup is essential. Review the different steps and required certifications.

Still unsure? Consult your insurer or broker. They can answer your questions and adjust your coverage if needed. It all comes down to risk—and especially your risk tolerance.

Preventive tips to reduce the risk of water damage

• Install a backwater valve inside your home to prevent sewer backup.
• Clean gutters regularly to prevent water from accumulating near the foundation.
• Watch for signs of infiltration (cracks, humidity) and seal them quickly.
• Shut off the main water supply when travelling to avoid prolonged leaks, or drain the pipes.
• Add water leak detectors. Some devices automatically shut off the water when a leak is detected, helping prevent major damage.

Simple actions that reduce the risk of property damage and long-term impacts.
