    "Amazing services at reasonable prices. Shai and his team were such wonderful people and extremely helpful in every little detail imaginable. Our garden looks better now with their help putting in all the pavers. We could have not managed this small project without their help."

    "We had a major kitchen remodelling project in our house including new cabinets, countertops and flooring. Even sinks were replaced. We expected a lot of headaches, delays and unexpected charges. With Spenser and his team none of that happened. He explained from the beginning what our options were, he gave his recommendations that we found quite reasonable. The job started when he said it would and he was regularly checking on the progress. Everything that we wanted to fix (and it wasn?t much) was done at no cost. They did an excellent job, the kitchen is beautiful!"

Idan communicated constantly and throughout the project and the results were better than expected in the full remodel of an upstairs bathroom. We will be using Bear Remodeling for our next project!"

    "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."

    "I first found Ivan through HomeAdvisor and decided to let him do remodel for my two bathrooms (rip out old cabinets and countertops and sinks and install brand new equipment that we furnished). He did a great job, quality of work was really good. Ivan never asked for any money from me until the job was 75% complete, and even then he only asked for a small portion of the total amount. I was very happy with his customer relationship skills and the workers that work for him. He stands behind his work. I was happy enough that I hired Ivan again to do a small kitchen remodel (careful demo of kitchen countertops, removal of dishwasher, install new owner furnished quartz countertop and dishwasher). He is still working on the project as I type this review, but I know the job will be done properly. I highly recommend Ivan for any residential addition or remodel project of any kind."

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.
