Ottawa water damage restoration costs in 2026 range from $2,500 for a contained Category 1 leak to $85,000+ for a Category 3 sewer-backup full-basement remediation. This guide breaks down 2026 pricing by water category, scope step, room size, and how insurance coverage interacts with out-of-pocket cost.
Category 1 (clean water — supply line, rainwater): $2,500-$8,500 for cleanup + drying (small to medium area). Category 2 (grey water — appliances, washing machines): $5,500-$22,000. Category 3 (black water — sewage, river flood, toilet overflow): $15,000-$85,000+ — all porous materials must be removed and replaced. Reconstruction adds 50-150% on top of restoration cost.
Emergency call-out: $245-$485 (waived if proceeding). Truck-mounted extraction (per hour): $145-$245. Submersible pump rental: $85-$145/day. Content protection/move-out: $345-$985. Initial moisture mapping report: $245-$485 (often included).
Equipment per day: air mover $35-$55, LGR dehumidifier $145-$245, hydroxyl generator $185-$345, desiccant unit (large) $385-$585. Typical 1,000 sq ft basement dry-out: 4-7 days, 6-12 air movers + 2-3 LGR dehus = $2,400-$5,800 in equipment. Labour for daily monitoring/moisture checks: $245-$485/day.
Flood-cut drywall (12-24 inch standard): $4.50-$8.50/linear foot. Carpet removal + disposal: $1.75-$3.25/sq ft. Vinyl plank/laminate removal: $2.25-$4.50/sq ft. Hardwood removal: $3.50-$6.50/sq ft. Insulation removal (Category 2+): $1.25-$2.85/sq ft. Cabinet removal (lower units, particle board): $185-$385 per linear foot. Trim/baseboard removal: $1.85-$3.50/linear foot. Dumpster/disposal: $385-$685 (small flood) to $1,850-$3,250 (full basement).
Antimicrobial treatment (Category 2+): $0.85-$1.85/sq ft of treated surface. Disinfectant fogging (Category 3): $0.65-$1.25/sq ft. HEPA air scrubbing: $185-$345/day per scrubber (typically 2-4 needed). Hydroxyl odor treatment: $585-$1,250 for typical basement.
If water event is older than 48 hours, expect mold scope. Assessment: $385-$685. AMRT-certified remediation: $12-$28/sq ft of affected surface. Containment (poly walls + negative-air HEPA): $585-$1,850. Air-quality testing (post-remediation, mandatory for insurance sign-off): $485-$985. Typical basement mold remediation: $3,500-$22,000 above the water restoration cost.
Category 1 (clean water): $2,500-$8,500. Category 2 (grey water): $5,500-$22,000. Category 3 (sewage/river): $15,000-$85,000+. Reconstruction adds 50-150% on top. A typical 1,000 sq ft basement flood (Category 2): $8,500-$22,000 restoration + $18K-$45K reconstruction.
Sudden burst pipes: yes (most policies). Sewer backup: only with backup rider ($50-$200/yr). Overland flooding: only with overland endorsement ($75-$300/yr). Gradual leaks: NEVER covered. Confirm your specific coverage before assuming.
Extraction: 4-8 hours. Drying: 4-7 days for typical basement. Mold remediation (if needed): 1-2 weeks. Reconstruction: 2-8 weeks depending on scope. Full timeline (water event to move-back): 3-12 weeks.
Most Ottawa policies: $500-$2,500 deductible. Some sewer backup riders carry separate higher deductibles ($1,000-$5,000). Confirm with your insurer before approving scope.
For very small Category 1 events (under 100 sq ft, less than 24 hours): possibly with rental equipment ($385-$685). For anything larger, Category 2+, or older than 48 hours: hire IICRC-certified pro — DIY drying that leaves hidden moisture creates $20K-$60K mold problems.
