Top One Plumbing Inc.

True Service Plumbing and Top One Plumbing Inc. are both genuine options in Ontario when a pipe is leaking and you need it found and fixed right, not just patched. Both score above 94 on our methodology, so the real decision comes down to how each one fits your specific leak and pipe situation.

The differences that matter

  • Emergency vs scheduled leaks. True Service advertises 24/7 emergency callouts with flat-fee upfront pricing, which matters if a pipe is actively flooding a basement at 2am, while Top One's strength is fast same-day or next-day scheduling for leaks that can wait a few hours.
  • Old pipe replacement experience. True Service's reviews specifically call out old-house pipe replacements and downtown Toronto condo work, useful if your leak is coming from aging or outdated plumbing rather than a single fixture.
  • Residential and commercial range. Top One's technicians are praised for handling both residential kitchen and bathroom leaks and commercial drain jobs, so it's a fit if the property in question is a mixed-use or commercial space.
  • Review volume and track record depth. True Service has built its five-star record across 1,220 reviews versus Top One's 383, giving it a longer paper trail on pipe repair jobs specifically, though Top One's own reviewers report no recent complaints across its total.
  • Named technicians for diagnostics. True Service reviewers name a wider bench of techs (Raymond, Niko, Max, George, Randy) for clear pre-repair explanations, while Top One reviewers most often credit Mark and George for fast, no-delay diagnosis.

Top One Plumbing Inc.

Top One Plumbing Inc.

Every recent review rates Top One five stars, with customers reporting same-day or near-same-day availability and technicians (especially Mark and George) who diagnose problems clearly and fix them without delays.

Which should you pick?

Pick True Service Plumbing if

  • A pipe is actively leaking or burst outside business hours and you need a 24/7 emergency response
  • You're dealing with an older home where the leak likely traces back to aging or original pipework
  • You want a flat-fee quote locked in before work starts

Pick Top One Plumbing Inc. if

  • The leak is in a standard residential kitchen or bathroom, or in a commercial space needing drain work
  • You want same-day or next-day service without needing round-the-clock emergency coverage
  • You'd rather go with a shop reviewers describe as having no recent complaints at all

Verdict

The choice here comes down to the shape of the leak, not the score gap between them. True Service Plumbing is the stronger pick when you're dealing with an emergency at odd hours or a pipe repair tied to an older home's aging plumbing, backed by a deeper bench of named technicians and a longer track record. Top One Plumbing is the better fit for a more routine residential leak or a commercial property, where its fast scheduling and clean recent record do the job just as well.
