Of course, you want great service and a job done on one level. Here are some targeted questions you can ask to make sure you are getting it right.
Are You Licensed?
You never want to hire someone to do electrical repairs unless they have a permit from your state for this type of work. Each country may have slightly different licensing requirements for electricians, but these requirements are in place to protect consumers.
A licensed electrician should not have the slightest problem presenting information about his license. After all, they worked hard to get that license. If the person you are trying to hire tries to change the subject or admit they don't have a permit, look elsewhere.
Do You Have Insurance?
Whenever a contractor works on your home, there is a very good reason to make sure you have the right insurance. If not, you can join if something goes wrong. You cannot be tried. In most countries, it is illegal to perform repairs as a contractor without adequate insurance coverage.
