10 Best Plumbing Contractors in Houston, TX

Plumbing contractors serving Houston

Before you hire

  • Check the license. Look the company up on your state or city licensing board and confirm the license is active for this kind of work.
  • Ask for proof of insurance. Liability coverage, and workers’ compensation if a crew will be on site.
  • Get it in writing. A written estimate should list the scope, materials, labor, permits, cleanup and how changes are priced.
  • Compare more than one quote. Two or three written quotes for the same scope make it easier to spot gaps.
  • Ask who does the work. Find out whether the company’s own staff or a subcontractor will be on the job.
  • Confirm the warranty. Ask what parts and labor are covered, for how long, and get it in writing.

Frequently asked questions

How do I verify a plumber is licensed in Houston

Check your state contractor licensing board website. Enter the plumber name or license number to verify active status, insurance, and any complaints or disciplinary actions

What is the difference between a licensed plumber and a handyman

Licensed plumbers complete 4-5 years of apprenticeship, pass state exams, carry insurance, and are legally authorized for all plumbing work. Handymen cannot legally do plumbing work requiring permits

Does it matter if a plumber is bonded

Yes. A surety bond protects you financially if the plumber does not complete the job or causes damage. It is an additional layer of protection beyond insurance
