    "I recently searched for a contractor to remodel various rooms in my home in Lafayette, California. After interviewing several contractors, my cousins in Walnut Creek recommended Avi Matalon, RMO of Creation 7. They had Avi rebuild a guest house on their property which had been demolished by a large fallen Oak Tree. After seeing Aviâ s work and meeting with him, I hired him immediately. Avi and his team worked professionally, were most respectful of my home and did an outstanding job on my project. As construction projects go, we ran in to various issues throughout the job, such as Asbestos, which required professional abatement, an issue on the other side of our home completely unrelated, needing immediate attention due to the rain, and the ability to obtain siding which was no longer made. Avi was able to deal with and take care of all issues that came up during the remodel without incident. Avi always put me first in terms of ensuring I was kept informed and was comfortable with the work being done. He remained proactive throughout the project and visited my home some weeks daily to ensure all was going to perfection. He always remains calm, professional and has the most incredible demeanor of anyone I have ever worked with on a business level. I HIGHLY recommend Avi and his company for your remodel needs. Again, as issues come up, Avi is the man you want for your home remodel project."

    "I hired Cerletti and Kennedy for a Sunroom/Patio Enclosure. They were the only company I spoke to who offered reasonable solutions for the design, and flexibility if I decided to add something to the project later. They had expertise regarding the materials and design that were not mentioned when I spoke with other companies. When a part arrived that was damaged, they took care of it immediately and it did not even delay the project. And the project was completed exactly on budget. My sunroom is BEAUTIFUL, I am SO PLEASED! I highly recommend them!!!"

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.
