Water Damage Complete Guide
When Water Enters Your Property, Every Hour Counts
Water damage is deceptively destructive. What begins as a burst pipe, an overflowing appliance, or a flooded basement can escalate into structural damage, mould growth, and significant financial loss within 24 to 48 hours. In Canada, where freeze-thaw cycles, spring flooding, and heavy rainfall events are part of life, water damage is one of the most common and most costly property insurance claims.
WINMAR® has been restoring Canadian homes and commercial properties since 1977. Our restoration professionals respond 24 hours a day, 7 days a week, 365 days a year because water damage does not follow a business schedule.
From coast-to-coast, TRUSTED since 1977.
What Causes Water Damage?
Understanding the source of water damage helps determine the correct restoration approach. The most common causes our teams respond to across Canada include:
- Burst or frozen pipes, especially during Canadian winters when temperatures drop rapidly
- Appliance failures including dishwashers, washing machines, refrigerator ice makers, and water heaters
- Roof leaks from ice dams, storm damage, or aging roofing materials
- Basement flooding from groundwater intrusion, failed sump pumps, or blocked weeping tile (note: WINMAR® does not repair or replace weeping tile itself, but we are your first call when blocked or failed weeping tile results in flooding)
- Sewer backups, particularly after heavy rainfall overwhelms municipal systems
- Flooding from rivers, lakes, and overland water, increasingly common due to changing weather patterns
- HVAC condensation and leaks, often hidden behind walls or above ceilings for extended periods
The Three Categories of Water: Why Classification Matters
Not all water damage is treated the same way. Restoration professionals use a standardized classification system to determine the appropriate response and safety protocols:
Category 1 — Clean Water
Water from a clean source such as a broken supply line or overflowing sink. This category presents the least immediate health risk but can degrade quickly if left untreated.
Category 2 — Grey Water
Water containing contaminants that may cause illness if ingested or contacted. Sources include washing machine overflow, dishwasher discharge, and toilet overflow without feces. Protective equipment and careful handling are required.
Category 3 — Black Water
Highly contaminated water from sewage backups, flooding from rivers or streams, or water that has been sitting long enough to allow bacterial growth. This category requires full personal protective equipment, antimicrobial treatment, and often the disposal of porous materials.
Why This Matters for You
If a contractor does not ask about the source of your water damage or skips classification entirely, that is a warning sign. Proper classification before any work begins protects both your property and your family’s health.

The WINMAR® Water Damage Restoration Process
WINMAR® crews offer prompt and professional service to help our customers get back to pre-loss life with the least amount of interruption and associated costs as possible. Our certified teams follow a proven, step-by-step process on every job:
- Emergency Contact & Rapid Dispatch: Call us any time. Our national network means a local team is always nearby.
- Inspection & Damage Assessment: We use moisture meters, thermal imaging cameras, and hygrometers to map the full extent of damage, including hidden moisture behind walls, under floors, and above ceilings.
- Water Extraction: Industrial-grade extraction units remove standing water quickly. Speed here dramatically reduces overall restoration time and cost.
- Drying & Dehumidification: Commercial-grade air movers and dehumidifiers create optimal drying conditions. We monitor moisture levels until structural materials return to acceptable levels.
- Cleaning, Sanitizing & Odour Removal: Affected areas and salvageable materials are cleaned and treated with antimicrobials. We address odour at the source, not just the surface.
- Restoration & Repairs: From replacing drywall and flooring to full reconstruction, WINMAR® handles the complete restoration. One call, one company, from damage to done.
Water Damage and Mould: The Hidden Consequence
One of the most serious secondary risks of any water intrusion event is mould growth. Mould spores are naturally present in most environments and only need moisture and an organic material to colonize. In the right conditions, mould can begin to establish itself rapidly after a water event.
This is why rapid response to water damage is so critical. WINMAR®‘s water damage restoration process is specifically designed to remove moisture before mould has a chance to establish. When mould is already present, our remediation teams handle that too, ensuring the full scope of damage is addressed.

Protecting Your Property: What To Do While You Wait
While waiting for your team to arrive, there are safe steps you can take to minimize further damage:
- Shut off the water source if it is safe to do so
- Turn off electricity to affected areas at the breaker panel; do not enter flooded rooms where electrical outlets may be submerged
- Move valuables, documents, and electronics to a dry area if safe to do so
- Do not use household fans or your home HVAC system to attempt drying, as this can spread contamination
- Document everything with photos and video before any cleanup begins; your insurance company will need this
- Contact your insurance company and call WINMAR® simultaneously
Does Insurance Cover Water Damage Restoration in Canada?
Most standard Canadian homeowner’s insurance policies cover sudden and accidental water damage such as a burst pipe or appliance failure. However, coverage varies significantly between policies and insurers. Overland flooding and sewer backup coverage are typically offered as separate endorsements.
WINMAR® works alongside all major Canadian insurance companies. Our documentation process is designed to support your claim from day one, and our project managers can communicate directly with your adjuster on your behalf.
Tip for Homeowners
Review your insurance policy before a loss occurs. Confirm whether you have sewer backup coverage and overland flood coverage. Many Canadians discover gaps in their coverage only after an event.

Frequently Asked Questions: Water Damage Restoration
We operate 24/7/365. Response times vary by location, but our goal across our national network is to have a team on-site as quickly as possible.
It depends on the extent of the damage. Minor water damage may not require you to vacate. Significant damage involving Category 2 or 3 water, or large-scale drying equipment, may make staying impractical or unsafe. Your project manager will advise you based on the specific conditions.
The timeline depends on the materials affected, the amount of moisture present, and the scope of repairs required. Your project manager will provide an estimated timeline once the assessment is complete.
WINMAR® offers professional contents cleaning and pack-out services. Many items that appear to be beyond saving, including furniture, documents, clothing, and electronics, can be successfully restored with professional treatment. We assess each item individually.
