Water damage is the #1 home-insurance claim in Ottawa — burst pipes, ice-dam backups, sewer backflows, sump-pump failures, and Rideau/Ottawa River spring floods. The first 24-48 hours determine whether you face a $4K cleanup or a $40K mold-remediated structural rebuild. This page covers what Ottawa water damage restoration contractors actually do, 2026 emergency pricing, IICRC certification requirements, and how to coordinate with your insurer.
IICRC classifies water by contamination: Category 1 (clean water from supply lines, rainwater): safe contact, dryable in place. Category 2 (grey water from dishwashers, washing machines, aquariums): contains contaminants, may cause illness, requires sanitization. Category 3 (black water from sewage, sea/river flooding, toilet overflows past the trap): grossly contaminated, all porous materials (drywall, insulation, carpet, particle-board cabinets) must be removed and replaced. Ottawa basement fl...
(1) Emergency extraction — submersible pumps and truck-mounted extractors remove standing water (typically within 4-8 hours of call). (2) Content protection — furniture and salvageable items removed to dry storage. (3) Demolition — removal of unsalvageable drywall, insulation, flooring, baseboards (12-24 inch flood cuts standard). (4) Structural drying — commercial air movers and dehumidifiers (LGR-class) deployed for 3-7 days; moisture meters used daily to verify drying to <16% MC in wood, <12%...
Emergency call-out: $245-$485 (waived if work proceeds). Hourly labour: $95-$155 per technician. Equipment rental (per day): air mover $35-$55, LGR dehumidifier $145-$245, hydroxyl generator $185-$345. Typical Ottawa basement flood (1,000 sq ft, Category 2): $8,500-$22,000 cleanup + drying + antimicrobial. Reconstruction (drywall, insulation, paint, flooring): adds $12,000-$45,000. Category 3 sewer backup full basement: $35,000-$85,000+ all-in. Most projects are insurance-funded — contractor inv...
The Institute of Inspection, Cleaning and Restoration Certification (IICRC) is the industry standard. Required certifications for Ottawa water restoration: WRT (Water Damage Restoration Technician), ASD (Applied Structural Drying), and AMRT (Applied Microbial Remediation Technician) for any project where mold growth has begun. Insurance companies often require IICRC-certified contractors on claims over $10K. Verify at iicrc.org.
Reputable Ottawa water damage contractors: (1) Call your insurer with you on speakerphone within 2 hours of arrival, (2) document everything with timestamped photos and a moisture-mapping report, (3) invoice your insurer directly (often the contractor receives payment from the insurer and you pay only your deductible), (4) provide IICRC-compliant scope documentation that insurance adjusters accept without dispute. Avoid contractors who push 'public adjuster' services — these add 10-15% to your c...
Mold begins growing on damp organic materials (drywall, wood, insulation) within 24-48 hours of water exposure. If your water event is more than 48 hours old when restoration begins, expect a mold assessment ($385-$685) and likely an AMRT-certified remediation scope ($3,500-$22,000+ depending on extent). Hidden mold inside wall cavities and under flooring is the #1 reason DIY drying fails — only forensic moisture mapping catches it.
Reputable 24/7 firms respond within 1-2 hours of call. After-hours and weekend response is standard in the industry — water damage doesn't wait for business hours.
Typical 1,000 sq ft basement flood (Category 2): $8,500-$22,000 for extraction + drying + antimicrobial. Add $12K-$45K for reconstruction. Category 3 sewer backups: $35K-$85K+ all-in. Most claims are insurance-funded.
Coverage depends on cause: sudden burst pipes (yes, most policies), sewer backup (only with sewer backup rider — Ottawa-area sewer backup riders run $50-$200/year), overland flooding from Rideau/Ottawa rivers (only with overland water endorsement), gradual leaks (no — excluded from most policies).

24-48 hours. Mold begins growing on damp drywall, wood, and insulation within 2 days of exposure. If your water event is older than 48 hours, expect mold assessment and likely AMRT-certified remediation in scope.
