    "Jose, is a great guy and so is his crew. He has the best communication skills of any contractor i have dealt with. They show up on time, courteous and always clean up at the end of the day. He went above and beyond and did extras without additional charges. We couldn't be happier with how the project came out. We are so lucky to find a contractor that we can use for many other projects. Jose company provides so many services. Pricing was extremely fair, don't call anyone else, use Jose."

    "Really great experience with this company. We needed emergency repairs for a leak initially and they did such a good job we had them do some additional tiling work afterwards. Would definitely hire them again."

    "Anderson is a miracle worker, installing a shower in our basement bathroom when other contractors said it couldn’t be done or would be outrageously expensive. Anderson did the work in a short time, cleaned up all the debris and left it spotless. His cost was very reasonable and he used his contractor’s discounts for the materials. He communicates very well so I knew when he was coming and going. I was consulted at every step. I highly recommend Home Innovation!!!"

    "I recently finished renovating my apartment with MCI Renovation, and I am extremely pleased with the outcome! The team did an outstanding job with the painting, installing a new French door for the kitchen, and putting up curtains for my windows. What stood out most to me was the care with which everything was done, and how they made sure to meet the deadlines we had discussed. It was really important to me that the work was done neatly and on time, and they delivered on both fronts. A special thank you to Vitalii for his professionalism and for genuinely listening to my needs throughout the process. His attention to detail and excellent communication helped everything run smoothly. I highly recommend MCI Renovation to anyone seeking high-quality work and a dependable team!"

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.
