What questions should I ask before hiring a plumber?

Before hiring a plumber, focus on verifying their credentials, understanding the scope of work, and protecting yourself financially. The right questions upfront can save you from costly mistakes, poor workmanship, and potential liability issues.

Licensing and Insurance Verification is your first priority. Ask to see their Ontario plumbing license number and verify it's current through the Ontario College of Trades. Request proof of WSIB coverage and liability insurance - legitimate plumbers carry at least $2 million in liability coverage. In Ottawa, many plumbing jobs require permits, so ask if they'll handle the permit application and inspections.

Get detailed project information by asking for a written estimate that breaks down materials, labor, and timeline. Ask about the specific brands and grades of materials they'll use - quality varies significantly in plumbing components. Find out their warranty policy on both parts and labor, and whether they guarantee their work. Ask about potential complications that could increase costs, especially for older Ottawa homes with aging infrastructure.

Understand their business practices by asking for local references from recent jobs. Ask about their emergency service availability and response times. Find out their payment structure - reputable plumbers typically ask for minimal money upfront and never demand full payment before starting work. Ask if they clean up after themselves and protect your home during the work.

Red flags to watch for include door-to-door solicitation, demands for large upfront payments, no fixed business address, or pressure to sign immediately. Be wary of estimates significantly higher or lower than others - both can indicate problems.
