    "We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

    "Richard and his team at 3D remodeling are absolutely phenomenal! We had a MAJOR home renovation which included Kitchen, Master Bath, Guest Bath, Powder Room, Children Rooms, Room expansions etc. What I like most about Richard is his professionalism, the man is always on time when and would never cut corners. His team is clean as well, everyday the house was left tidy. He cares about quality and about customer satisfaction. He is cordial and kind. He is quick and precise with his timelines and doesn't cut corners! Richard made us feel like family from day one. He puts his blood sweat and tears into his projects. I would no double hire him again if given the opportunity. Thank you so much for all your hard work in creating our dream home Richard!"

    "I have nothing but praise for Young and his exceptional crew. We needed a contractor for a full house remodel and felt unsure after meeting several others, but everything changed when we met Young. He was punctual, courteous and understood exactly what we wanted, and his expert knowledge helped us make the right decisions. We hired his team with confidence, and they exceeded every expectation. The project finished far faster than other contractors estimated, without compromising quality. Each step was organized, efficient and professionally handled. The final result was amazing, and the hardest part for us was simply choosing designs. Even then, Young guided us with helpful suggestions that turned out beautiful and modern. I absolutely loved the end result and still enjoying every moment in my new home. I strongly recommend Young and his team. They made a major remodel surprisingly smooth, pleasant and truly enjoyable."

    "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."

    "I wanted to replace carpet with wood-look vinyl in living room, dining room, library and office in my house, but the floors were very uneven. One company said they would only recommend replacing with new carpet and a second company gave me a ridiculously high estimate for the work. Jacobs Construction quoted a fair price, which went up a bit when they pulled up the carpet and saw just how bad the floors were. The final cost was far below the other quote. The work was done in just two days, and the floors are beautiful!"

Jorge and the A-Right crew were the most responsive contractors I have ever worked with and in my opinion that made the entire process less stressful and much easier. I will definitely be referring A-Right builders to all friends and family who are interested in having any type of remodeling done and I am already in the process to utilize them to retile the rest of my home. Thank you Jorge & Andy"

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.
