"I engaged Harrison Sons LLC for a full kitchen restoration, and I could not be more pleased. Their professionalism and communication skills are exceptional, and their work ethic, along with the cleanliness of their job, is truly remarkable."

"During a very busy time for them due a recent wind storm, they were the first to provide a quote. This helped to get something to my insurance company and get the ball rolling. Other contractors either did not return my calls, phones were turned off, or were a lot further out to even give me a quote. The quote was reasonable and the work was excellent. They even helped me pull out a tree stump that was not part of the estimate. The extra hand was a huge help. They got the job done fast and did a good job of cleaning up. I will hire them again."

"We started with one project with Mass Design, and were so pleased with their work that we added two additional home improvements as well. They truly care for their clients and go above and beyond when working to meet their needs. My wife and I found it surprising how carefully they listen. Things mentioned as a passing comment were noted and acted on. Their workmanship and design skills were exceptional, their communication clear and concise, and we were never left in question about any step of the process. In addition, we truly appreciated their honesty and transparency. Simply put, fantastic to work with. I would highly recommend using their services and we have more projects down the line where we will be using them."

"Mike and his crew did an amazing job on our basement. Not only did they finish the project ahead of schedule, they also helped replace parts of our stairs at no extra cost and were extremely flexible and easy to work with throughout the project. If I ever have any other major home remodels or framing needs, or friends/family that need the same, I am for sure going to start with MSW as a top tier option!!"

"A&C was fantastic to work with. I would definitely recommend them and have already recommended them to several of my friends. I had a hard time getting people to come out and give me a quote but they came out right away. The quote was reasonable and so hired them. I had them remodel my small and only bathroom so staying on schedule was important to me. I ended up picking smaller tile after I was given the quote so the project took a couple extra days but it was totally worth it. The team was really respectful of my home. They cleaned up after themselves and they weren’t excessively noisy which was great because I was working from home. They all seemed to really like each other and worked as a really efficient team. The plummer and tile team that they work with were also great. A couple of faulty parts and unexpected things came up and they did a great job working around it and ended up finishing close to the expected time and cost that I was quoted. My bathroom looks beautiful. I feel like I really lucked out and I will definitely be hiring them for future remodel projects."

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.
