    "I hired them for a small bathroom remodel and was blown away by their attention to detail and professionalism. Francisco was a pleasure to work with - he listened to my needs and provided great suggestions throughout the project. The end result exceeded my expectations and I couldnt be happier with the outcome. I highly recommend Francisco and will definitely be using them for future projects."

    "If you need reliable contractor, my strong recommendation is Palm Construction. I hired them to build a deck and they did phenomenal job. Ray and his brilliant team made this project simple and non painful. I worked with many contractors and this was my best experience. They also charged at the end very reasonable final price, although quality of materials is superb. I can't recommend enough!"

    "The team at Pure Home Remodeling did a fantastic job. We have completed two renovations with Pure Home Remodeling and the second one was just recently. They converted our existing master suite to an additional bedroom with walk-in closets, painted the hallway with addition of crown molding and remodeled the patio. In the patio, they did all the hard-scape (fire pit/table and BBQ area). The paperwork from the estimate all the way to the finish of the work, was organized in details and they finished the entire work with a minor delay. Most of the delays happened because there were several issues with the materials that we purchased and they were not in stock. Most project issues that were raised during the work, were handled professionally by our project manager, his team and subcontractors which helped tremendously in solving them quickly and efficiently. We can't be happier with this entire experience with them and mainly with the way this remodeling came out, because we know personally about bad cases where work was not done professionally OR they were abandon in the middle. We are very thankful that our remodeling project went like that."

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.
