Emergency Response Steps

Time is critical with water damage. Mould can begin growing within 24-48 hours in Ottawa's humidity. The faster you respond, the less damage and lower the restoration cost. Immediate actions: stop the water source if possible (shut off the main water valve, turn off the water heater), turn off electricity to affected areas (if safe to do so — don't enter standing water to reach the panel), remove valuable items from the water, and begin removing standing water with a wet/dry vacuum, mop, or pum...

The Restoration Process

Phase 1 — Water extraction (hours 1-24): industrial pumps and vacuums remove standing water. Moisture meters and thermal cameras identify hidden water behind walls, under floors, and above ceilings. Wet materials that can't be saved (saturated drywall, padding, insulation) are removed immediately. Phase 2 — Structural drying (days 2-5): industrial dehumidifiers and air movers dry the structure. The goal is reducing moisture content to pre-loss levels (typically below 15% for wood). Daily moistu...

Mould Prevention After Water Damage

Mould is the most serious secondary consequence of water damage in Ottawa. Ottawa's humidity combined with organic building materials (wood, drywall, carpet) creates ideal mould growth conditions. Mould begins growing within 24-48 hours of water exposure. By 72 hours, established colonies can form. This is why immediate professional response is critical — every hour of delay increases mould risk and restoration cost. Professional mould prevention includes: rapid structural drying to below 60% ...

Insurance Claims for Water Damage

Water damage insurance coverage depends on the source. Generally covered: burst pipes and plumbing failures, appliance malfunctions (washing machine, dishwasher), ice dam damage, and accidental discharge of water. Generally NOT covered: gradual leaks that were neglected, flooding from external water sources (rivers, overland water) — requires separate overland flood insurance, sewer backup — requires a sewer backup endorsement (add it to your policy if you don't have it, typically $30-$100/year...

Can I clean up water damage myself?

Minor clean water spills can be DIY-managed with wet/dry vacuums and fans. Any significant flooding, grey water, or sewage requires professional restoration. The equipment and expertise needed for proper structural drying far exceeds consumer capabilities.
