Bath Contractor CheckLook up a bathroom contractor's license before you sign anything

Top-rated bathroom contractors near Piedmont, CA

Piedmont doesn't have a license file on this site to search, so below is a ranked list of its 10 highest-rated bathroom contractors on Google Maps instead. Ranked is not the same as checked: run any name through your state's or city's own lookup before you decide anything. A high star average says nothing about whether a business holds the license or registration your state or city requires.

Google Maps ratings checked · How we rank

Piedmont bathroom contractors, ranked by Google rating, not searchable by license

The order below gives review volume nearly as much weight as the star count, since there's no license file here to search; treat it as a starting point, never as proof of a license or registration, and run the name yourself before you sign anything.

How to check a license in California

  1. Open CSLB's Check a Contractor License tool.[1]
  2. Enter the license number, the business name, or a name tied to the license. Numbers here run digits only, never letters.[1]
  3. Read the license status and disciplinary history, plus the workers' compensation and insurance information on file.[2]
  4. When the contractor arrives to bid the job, ask to see their pocket license and a photo ID, and confirm the person matches it.[2]

Warning signs

  • A bid that lands far below every other one you collected.[2]
  • No current business address on file, only a cell phone number.[2]
  • A blank or partially blank contract or change order.[3]
  • A deposit request above the legal cap without a bond to justify it.[2],[3]

Rules that protect you

  • Contractor bond of 25,000 dollars, covering every job during the life of that bond, not per project.[2]
  • Down payment capped at 10 percent of the contract price or 1,000 dollars, whichever is smaller, with a single exception for a contractor carrying a Blanket Performance and Payment Bond.[2],[3]
  • Written contract required once a job passes 500 dollars combined for labor and materials; changes must also be in writing.[3]
  • Three-day written right to cancel a signed home improvement contract.[3]

Before you search, know what to look for

  1. Does the license status say active, not expired, suspended or revoked?
  2. Does the business name and license number match exactly what is on the bid or contract?
  3. Is there any disciplinary history attached to the license, and if so, what was it for?
  4. Does the license class actually cover bathroom work, or is it a different trade entirely?
  5. Is the bond or insurance information on the record current?
  6. Does the address on file match a real, current place of business?
