    "We couldnâ t be happier with our remodel. New Wave Design and Build owner Eran Ozeri and his team were very easy to work with; their attention to details impressive. Eran understood our vision and transformed the entire upper level of our home into a beautiful new living space. His communication skills are impressive, he contacted us daily and gave us updates throughout the build process. Eran takes great pride in his work. He went above and beyond to ensure that we were happy with all elements of the remodel. Whenever the project encountered a problem Eran always figured out a solution that did not compromise the plan/design. We will definitely be using New Wave for our next project, and have already recommended him to several of our friends."

    Title
    Murrieta, CA·

    "Al and his assistant installed two window air conditioning units in windows that another installer said could not be done. The other installer from TaskR installed one of the units in a non-preferred window and left quite a mess, including crooked drill holes in my wooded sills. (My place is 105 years old, but my window sills have metal frames and modern windows.) Al and his assistant’s work was perfection! I was so pleased, I have already referred Al to 2 neighbors. Al is great at communication, very pleasant to work with, and honest. They cleaned up everything and offered to take the boxes and packing materials out to my bins. This was a relatively small job, but worth the money. Al charges a 2-hour minimum, which is more than fair. I will hire Al again and continuing recommending him and his team."

    "Jim is a great guy to work with!!! He was very understanding and responsive to all my questions and concerns. He oversaw the entire operation of removing a wall to open up the living area. This encompassed general demo and construction, electrical, resurfacing, matching texture and repainting. Followed by some special hardwood floor detail work. His team of workers are always excellent and considerate of us and our home. You will not be disappointed! It is very difficult to try and choose a contractor and I feel lucky to have found him!!"

    "We recently hired Pen and Mason to expand our pantry, build a custom coffee bar, install new electrical outlets, and replace the carpet on our stairs with beautiful vinyl plank flooring — and we could not be happier with the results! From start to finish, their team was professional, friendly, and attentive to detail. They took the time to understand our vision, offered helpful suggestions, and executed the work flawlessly. The pantry expansion is so functional, the coffee bar is my new favorite spot in the house, and the new flooring completely transformed our stairs. They also handled the electrical work seamlessly, ensuring everything was up to code and perfectly placed and they also put up with my picky husband in the process."

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.
