    "After I contacted Angie, Rielsan called and was able to come out same day to give an estimate. He gave a very reasonable estimate compared to another I had received, and didn't try to upsell me. He also completed the job later that afternoon. The whole process was smooth and efficient. Will definitely be hiring back for future jobs."

    "We met with a few companies regarding our kitchen project before we ended up choosing Shai with Cal Green Remodeling. We picked him because of the knowledge he had and confidence he gaves us. He provided us with great ideas and a detailed estimate and timeline of what we could expect. His price was not very different than the others, however, his presentation was. Some of the other companies missed the mark on the details, which for us was very important considering this project was not cheap. Shai, had an answer to all of our questions and he offered us realistic expectations. Upon completion of our kitchen, we must say, we are super pleased with the results. We especially love the new island we added. Everything came out well and clean. The workers were efficient and kept the area clean during the renovation process. Shai was also readily available if we had any questions. I only wished we have used him for our bathroom remodeling project last year. Iâ m sure we will be using them again in the future!"

Frequently asked questions

  • It’s important that you verify their license is still in good standing. Also keep in mind that certain states or provinces don’t require licensing if the job is under a certain dollar amount.
  • You can find a list of your state’s licensing requirements on the HomeAdvisor website. Before you get to work with the pro, make sure their qualifications are current and acceptable to you.
  • It is always a good idea to get a copy of the pro’s insurance certificate for future records, and in case anything happens. This is a good way to feel more secure in your home project, and to weed out potential scammers.

HomeAdvisor makes it easy to connect with pros near you. You can read reviews, get quotes and book appointments all in one place.

Depending on the type of project, you may find subtle differences in the hiring process. Here’s a look at task-specific advice.

You can use HomeAdvisor to help evaluate a contractor’s qualifications. We put pros through a screening process, and award badges to high-performing contractors. You can find these badges on a pro’s HomeAdvisor profile, and sometimes, his or her website. 

Your research doesn’t stop here. Once you’ve found a few prospective companies, make an call to ask a few questions about work history, licensure and more:

  • Have you completed a job like this before?
  • Do you have a list of references I can contact?
  • When are you able to start the job?

In most cases, the responses you get to these three questions will give you a very good idea of the right pro for your project. If you have more than one front-runner, these additional questions can help you narrow it down. 

  • How many years of experience do you have?
  • What’s your permanent business address?
  • Are you licensed to work in my area?
  • When did you earn your business license?
  • How do you handle warranty service complaints?
  • Do you have worker’s compensation, property damage and personal liability insurance?

Any good contractor will answer these questions, and most will appreciate dealing with a client that takes such an active interest in finding good service. On the other hand, if a contractor gives you a hard time with these questions, you probably want to find someone else.
