What Does a Plumbing Contractor Do?


A plumbing contractor handles the installation and repair of water, sewage and natural gas pipes throughout a home, as well as interior and exterior faucets and fixtures. Plumbing contractors are also trained to work with water mains, septic tanks, laundry appliances, water heaters, sump pumps and other plumbing and pipe systems. Because plumbing work is done largely behind walls and beneath floors, some plumbing contractors can repair or replace tile, stonework and other surfaces. Although some Ontario plumbing contractors are generalists, others specialize in specific areas: residential emergencies and repairs, remodeling, natural gas lines, sprinkler systems and more.

Questions to ask a prospective plumbing contractor:


  • How long have you been in the business?
  • How many projects like mine have you completed?
  • Who will be working on the project?
  • Are the workers employees or subcontractors?
  • Can you provide me with references?
  • Are you and your employees licensed and insured?
  • What license(s) do you have?
  • How do you charge, and what does that include?
  • Can you give me a written estimate?
  • What do your services include?
  • How will I be charged for parts and materials?
  • Who will make repairs to any structural damage that results from the job?
  • When can this job get done?
  • What happens when cost exceeds the budget? What about changes to materials or labor pricing?
  • What will I need to provide?
  • Are there any important considerations or concerns you foresee with this project?
