"I highly recommend Beverly Builders Group. This was the smoothest remodel l've ever experienced. Elron and his crew were perfectionists. Have you ever had a contractor who cared more about detail than you? They were the most responsible company l've ever worked with. They did everything on schedule and everything they did was beautiful and the craftsmanship was amazing. We were living in the house while they worked and they were so clean and careful. They completely remodeled a very large bathroom and a guest bath. Everything from the ground up. I can't say enough about them. I'm so glad I chose them. I lucked out!"

"I hired a large company who hired ProServ as the contractor for the project. My contractor was incredible and efficient. Regretfully the company was not. Carlos, ProServ owner, made an incredibly awkward situation work out. I would give ProServ and especially Carlos rave reviews. The professionalism and honesty of the contractor and his crew is exemplary and quality of his work is exceptional."

"We had several contractors give us estimates and Ani of LGC was the best. She was knowledgeable, professional and not pushy at all. My husband and I felt very comfortable with her and it didnâ t take us long to choose her. She helped with the design, locating materials and also helped us save money. The workers arrived on time, put in a full dayâ s work and did an amazing job for us. What started as a primary bathroom remodel turned into primary bedroom, bathroom and master closet redo, flooring to most of our house and two patio redos. We felt comfortable with the entire process from start to finish. Ani and her crew kept us informed and helped with giving us other options that we didnâ t even think of. In a few weeks they will put in a beam in our family room. Iâ m very excited. The entire crew were very professional, knowledgeable, neat and cleaned up afterwards. We will definitely use them again. We couldnâ t be more happier with the choice we made. It was the RIGHT one."

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.
