    "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."

    "Emil did a wonderful job of explaining all aspects of the project during the sales presentation. Anthony and his painting crew did all that was contracted and more! As the job progressed, it was evident that more trim work was necessary. Anthony listened patiently and completed the entire painting job ahead of estimated completion."

    "My wife and I could not be happier with our master bedroom addition and new Walk in Closet. 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"

    "As a new homeowner, I was at first concerned about hiring contractors for home improvements for my condo. Being a realtor myself, I'd heard some horror stories. However, this is why referrals are so very important; for my second window quote I was put in touch with Alex at Home 2 Renovate. From the original handshake, the thorough quotation and the hierarchy at the company providing samples to my HOA (for their approval) to the installation of the windows and sliding door, it was painless and stress-free for myself. The install itself was an eye opener; the guys worked fast & efficiently, and really knew what they were doing, even on my second story windows. Living close to Sunset Blvd, the first major benefit I noticed was the significant sound difference compared to my old windows, its simply amazing! They look great, I'm over the moon. In my line of work, I won't hesitate to recommend Alex and the team. Look forward to working with you more in the future, thanks guys!"

    "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."

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.
