Pryde Group Corp

★5.0(204)·✓ Google-verified

Pryde Group Corp delivers consistent five-star results across sewer, drainage, and waterproofing work. Customers repeatedly praise the speed of response, the named crew members (Nick, Andrew, Andriy), and how thoroughly they explain jobs before starting. Pricing lands fair rather than rock-bottom, and reviewers note careful site cleanup even on major excavations. The crew handles everything from simple drain repairs to full sewer line replacements and basement waterproofing. Many mention receiving photos during work, help applying for city rebates, and same-day or next-day site visits. No complaints appear in recent reviews; the consistency suggests the team has refined its process and keeps close communication from quote through completion.

★5.0(85)·✓ Google-verified

Coldstream earns consistent five-star ratings for fast response, named technicians like Jahmar and Paul who explain work clearly, and trustworthy repairs.

Most calls get answered directly and dispatched fast, often within hours even late at night. Work quality and pricing are reliable for routine jobs like clogs and leaks. But some customers report Viktor was dismissive, blamed them for pre-existing issues, or quoted much more than competitors charged for the same problem. A few felt pressured to pay without questioning the scope.

G.O.Tap Plus.

★2.4(51)

Two in three reviews are one or two stars. Customers report inflated bills (4+ hours for routine valve swaps, parts marked up 10x retail), botched installations that caused leaks and water damage, and sump pump work that failed under warranty. Staff behaviour complaints span rude phone etiquette, aggressive driving, and unsafe job conduct. A handful of reviewers praise Alex L. for efficient drain work and responsive service, but the pattern of overcharging, failed repairs, and non-communication dominates.
