A water damage insurance claim can involve your insurer, an adjuster, and contractors. This guide offers a practical documentation checklist and questions to discuss with your insurer. It does not determine coverage or replace advice from your insurer, broker, or a licensed professional.

Why Coverage Can Differ

The Financial Consumer Agency of Canada explains (opens in a new tab) that home insurance may cover some unexpected events, such as water damage from a broken pipe, while flood damage from outside the home and sewer backup may require additional coverage. Maintenance-related damage may not be covered. Review your policy, endorsements, deductible, and the cause of loss with your insurer before making decisions about a claim.

Before You Call Your Insurer

The actions you take before calling your insurer can significantly affect your claim. Prioritize these steps:

• Ensure safety first. Address any electrical, gas, or structural hazards before entering the affected area.
• Stop the water source if possible. Turn off the main water supply if a pipe has burst. Document the location of the shutoff valve and the time you turned it off.
• Document everything before touching anything. Take photos and video of all affected areas, water levels, and the apparent source. This is your most important evidence.
• Do not throw anything away. Damaged contents, flooring samples, and drywall pieces are evidence. Keep them until your adjuster has assessed them.
• Ask before arranging non-emergency work. If you need to act quickly for safety or to stop active damage, record what happened and ask your insurer how it wants emergency work and documentation handled.

Filing the Claim

Contact your insurer using the reporting method in your policy. When you call:

• Have your policy number ready
• Describe the cause of loss clearly (burst pipe, sewer backup, appliance leak, etc.)
• Note the date and time of discovery
• Ask for a claim number — you will need this for all future communications
• Ask about your deductible and coverage limits for the specific cause of loss
• Ask whether you need to wait for adjuster authorization before beginning restoration work
• Ask which records, photos, estimates, or invoices it needs

Working with the Adjuster

Your insurer may assign an adjuster to assess the damage and determine coverage. Ask the insurer to explain the next steps for your particular claim. Useful questions include:

• Provide the adjuster with all documentation you have collected
• Ask the adjuster to explain any coverage exclusions in writing
• Ask how to submit additional information if new damage is discovered
• Read any authorization, scope, or settlement document carefully and seek independent advice if you do not understand it

Documentation Checklist

Thorough documentation is the foundation of a successful claim. Compile the following:

• Photos and video of all affected areas before any work begins
• Photos of the water source (burst pipe location, appliance, window, etc.)
• Written log of discovery date, time, and initial observations
• Receipts for any emergency expenses (hotel, temporary accommodation, emergency plumbing)
• Inventory of damaged contents with estimated values
• Moisture readings and drying logs from your restoration contractor
• Contractor invoices and scope of work documents
• Post-remediation reports and clearance testing results (if applicable)

Emergency Mitigation and Your Claim

Water can continue to damage a property after a leak or flood. Prioritize personal safety and stopping the active source where it is safe to do so, then ask the insurer what emergency steps it expects and which records it needs.

Depending on the cause and your policy, you may need to discuss steps such as:

• Emergency water extraction to prevent further spread
• Placement of industrial dehumidifiers and air movers
• Removal of wet materials that cannot be dried in place (carpet, underpad)
• Temporary boarding or tarping to prevent weather intrusion

Keep copies of any work records, invoices, photographs, and communications. Your insurer can tell you what it needs for your policy and claim.

Common Mistakes That Delay Claims

• Assuming coverage. Water damage can have different causes and policy endorsements. Confirm your coverage, deductible, and any exclusions with your insurer.
• Discarding damaged items before documentation. Always photograph and inventory damaged contents before disposal.
• Making undocumented decisions. Keep a dated record of the loss, communications, photos, estimates, and invoices.
• Starting non-emergency work without clarifying the process. Ask the insurer how it wants scopes, invoices, and approvals handled for your claim.

Working With Contractors

Before authorizing non-emergency work, ask your insurer about any documentation, approvals, or contractor requirements that apply to your policy. Ask any contractor for a written scope, estimated timing, and records of work completed.

Keep the insurer informed and retain copies of all records. Coverage decisions remain with the insurer under the terms of the policy.

Frequently Asked Questions

Does home insurance always cover water damage?

No. Coverage depends on the policy, the cause of loss, endorsements, exclusions, deductibles, and the facts of the claim. The Financial Consumer Agency of Canada notes that some water damage from inside a home may be covered while outside flooding and sewer backup may require additional coverage. Ask your insurer about your own policy.

What should I ask when I report a water-damage claim?

Ask for the claim number, the reporting contact, your deductible, coverage for the cause of loss, the documentation it needs, and how it wants emergency and non-emergency work coordinated.

What records should I keep?

Keep dated photos and video, notes about the cause and discovery time, claim correspondence, contractor scopes, estimates, invoices, and receipts for eligible emergency expenses. Your insurer can confirm the records relevant to your claim.
