The Hamilton, ON Local Code Shield
When hiring a plumber in Hamilton, verifying credentials goes far beyond a basic business license; they must hold an active Skilled Trades Ontario 306A Plumber license. Furthermore, works involving the City of Hamilton's Protective Plumbing Program (3P) require contractors to be registered with the city to ensure valid backwater valve installations and sump pump retrofits. Ensure your contractor pulls the necessary building permits for major drainage alterations, avoiding costly municipal fines and protecting your home's insurance policy.
