3. Aquamaster Basement Waterproofing Toronto
4.9 (281 reviews)score 91/100
Aquamaster brings Master Plumber and Plumbing Contractor licensing, a claimed history since 2009, and published rates that make quoting predictable (from $30/sq ft for crawlspace encapsulation to $700 for sump pump systems). With 281 reviews at 4.9 stars, inspectors like Roman, Albert, and Kevin walk homeowners through the actual problem before crews execute interior drainage, grading, and exterior membrane work.
- Detailed diagnosis before any work starts
- Named technicians oversee jobs start to finish
- Published, itemized pricing across 12 service types
- Basements reported dry through storms months later
Watch out: One reviewer flagged two cancelled appointments, though this is an outlier against a large review base.

5 (386 reviews)score 88/100
CD Flood & Sewer Water Damage Cleanup has run since 2003 and racked up 386 reviews at a 5.0 average, with technicians Mark and Jack repeatedly singled out for arriving within the hour of a burst pipe or flood call.

- Same-day response to flood and pipe emergencies

5. CJ Drain & Plumbing (Toronto)
5 (4 reviews)score 64/100
CJ Drain & Plumbing has just four reviews so this is a low-confidence pick, but all four are five-star and describe fast response and fair pricing on jobs ranging from sewage backups to urgent fixture repairs. Staff Jimmy and Ricardo are named specifically for treating customers with respect during stressful calls.
- Licensed plumbers claiming 13 years in operation
- Quick response to emergencies
Watch out: Review count is very small, so track record here is thinner than the others on this list.
