    "Kitchen and M. Bath My husband and I were facing our first remodeling project as first time homebuyers. We are so happy that we chose Beverly Builders Group for our kitchen and master bath remodel project. They did an amazing job! Roy and Lauren, were my leaders and designers, they came out to meet with me personally to discuss my needs and the vision that they have for our remodel project was stunning. They both really listened to me and also offered great suggestions and design advice. The team assigned to our kitchen master bath remodel project - from the demolition guys and frames to the tile guy, electrician, plumber, etc...were top-notch and did great work. During the entire process, if we had a question we could always call the office directly at any time. Now we want to remodel our other bathroom and garage. We did not even have to think twice. We will definitely go again with Beverly Builders Group for such a fantastic job the first time that we wanted them to do our next remodeling job too!"

    "We were in need of a major master bathroom remodel and were referred to Horizon Construction by a friend who had been extremely please with their master bath remodel. The owner, Mark, came out on time and gave us many suggestions based on the space we have and an estimate of the cost. We visited their show room several times to make our selections and were ready to begin. The workers all arrived on time and Mark supervised the project from start to finish. Mark was meticulous in making sure all work was completed to his and our satisfaction. The result is a beautiful travertine and quartz bathroom that we will enjoy for many years to come. We highly recommend Horizon Construction and Remodeling and will use the company for other remodel projects 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.
