    "We hired Josh Rutledge after having an awful experience with a different contractor. When we hired Josh, we were apprehensive after our previous experience with the other company. Through the course of our job, Josh completely restored our faith in his profession. He is beyond competent, and he takes great pride in the quality and consistency of his work. He totally blew our minds, and our house looks beautiful! He fixed all of the mistakes that were left by the previous contractor, and when he found mistakes that we didn't even know about he fixed those too! He's an all around nice guy, and pleasant to be around as he's got a very calm and friendly demeanor. We have already recommended Josh to friends and neighbors, and we will definitely use him for future projects! I only hope that we can book him, the quality of his work and his professionalism are surely going to keep him busy with all of the referrals he is going to be getting! We can't say enough about Josh and his work- if you hire him, you will have ZERO regrets!"

I spoke with Scott who was patient and helped me a lot even through our short conversations. Now I have a contact in mind should I need services in the future as I am sure this house will have something else come up."

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.
