What to ask before you hire

About Marlon Williams

  • Ask for their license number and check it with the state.
  • Ask what the warranty covers and for how long, in writing.
  • Search their name on the Better Business Bureau site, and read their reviews.

Worth asking any panel upgrade electrician

  • Can you show me proof of liability insurance and your bond?
  • What size panel, and does the utility need to change the service to my house?
  • Who arranges the power shutoff with the utility?
  • Who pulls the permit, and who meets the inspector?
