Stellar Work Construction earns a 4.9 rating from 44 reviews, with homeowners crediting Vlad and his crew for finally solving long-standing water issues after other fixes failed.

- Track record fixing water problems other contractors couldn't solve

5. Utilicon Services
5 (3 reviews)score 69/100
Utilicon Services has only 3 reviews on record, so treat this as an early-stage signal rather than a proven track record, but all three reviewers mention punctual arrival and clear updates during the work. It's worth a look for smaller jobs like drain and grease trap cleaning where those reviewers reported efficient, tidy service.
- Shows up on time
- Keeps customers informed throughout the job
Watch out: Only 3 reviews total, so there isn't much data to judge consistency at scale.

6. Basement Waterproofing Toronto - Foundation Crack Repair
4 (2 reviews)score 57/100
This foundation crack specialist has operated since 1991 and backs its sealing work with a 25-year warranty, a detail that stands out even with just 2 reviews on file. The one detailed review, though 6 years old, describes Toni walking through multiple solution options before starting and leaving clean, leak-free results.
- 25-year warranty on sealing work
- Detailed walk-through of solution options before starting
Watch out: Review count is very low and the most detailed feedback dates back 6 years, so recent performance is hard to confirm.
