    "I am totally thrilled with my newly renovated bathroom! Barak Builders did an incredible job completely transforming the space. I especially love the handheld shower next to the new bench, the pocket door, the adjustable lights, and the double sink vanity. The team helped me come up with an amazing design and select beautiful materials, and the end result is even better than I imagined. The workers were super professional and clearly took a lot of pride in their work. A big thank you to Shai and the whole Barak Builders team!"

    "Amazing is the best way to describe the service and work quality we got from Far Hill Construction. The owner Steven Davis was available for us every single time we called with questions regardless of the time of day. He was on site supervising and ensured we got everything we asked for. In some cases we messed up by not ordering enough supplies and he graciously solved the issue for us and did not add additional fees. We remodeled our office Break Room and the employees are all thrilled with the new space. Great work and great overall experience. Will absolutely be calling Far Hill Construction for any future projects that may come about."

    "David and Sam were very helpful and knowledgeable from start to finish. It was a large kitchen/bathroom remodel in an older house that also included a partial remodel on a third bathroom to install new plumbing and electrical for a washer and dryer. They started with a 3D CAD model of the kitchen done by their designer with input from me and then followed it exactly. The finished project was beautiful and looked even better than the drawings. There were several big challenges along the way including lowering the kitchen floor and also removing a load-bearing wall which required an architect and an engineer for city approval. They had all the contacts needed and I didn't have to go out and look for them myself. They also got all needed permits and approvals and were there for all inspections. Whenever a particular part of the project wasn't quite what I expected they cheerfully redid it until I was happy. They even fixed some problems that were caused previously by other contractors during an earlier remodel. David went to the tile store with me and was available anytime I had questions on appliances and fixtures. Sam, who was in charge of the structural work, was knowledgeable in every area of construction and personally did the trickiest framing and bracing work himself to make sure it was done right. Even though the project is done they come by whenever I have a question or see something that needs a minor adjustment. They are easy to reach, always cheerful, and never avoid me or leave me hanging. They were even flexible on the pricing and gave me different options depending on my available budget. I'm going to do a bathroom addition in a few years and am planning on using them for that."

    "Sean from First Stop Construction redid our master bathroom. We spoke with several contractors before choosing Sean. He was honest, straight-forward, and knew his stuff. His team did a great job on the suit. They came when the said they would and finished ahead of schedule. I recommend him often."

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.
