    "My husband and I chose Creation 7 to remodel/renovate our kitchen, open up the living area, redo the master bath, and create a brand new basement space with two bedrooms and a new bath. It looks GORGEOUS and we are so happy with our choice. We talked with several contractors/design build firms before finally deciding on Yaniv at Creation 7. As first-time homeowners, we had no idea what the process was like. We had a bit of a frustratingly slow start getting plans from our architect (a different company) but once we finally got the final plans to Yaniv and Creation 7, things moved SO FAST. His team was respectful of our home (we lived elsewhere) and hard-working (some were even there on Christmas Day which was really above and beyond!). When we did have problems or concerns (e.g., bath tile placement, countertop slab measurements) he remedied them until we were satisfied or credited the cost against future work. He is so easy to talk to and made the process (which was full of headaches and surprises that werenâ t their fault) clear and, dare we say, enjoyable? He was clear when change orders were going to be necessary (e.g., when they discovered that the foundation was crumbling) and was very transparent about costs. He was incredibly patient with us when we requested new little projects here and there (e.g., opening up the attic space, refinishing the floors) and was always immediately accessible when we had questions or needed to talk to him. We would absolutely use Creation 7 for any future projects and have already recommended them to friends!"

    Additions and Remodels

    "We hired Jonathan as our general contractor for a whole home remodel in April of 2019 for a single family home in Bernal Heights. Jonathan helped us along the way with everything from pulling the permits, working with the city, managing construction subcontractors, choosing finished materials with us, and final touches. We had very good communication with him throughout the process over text message and he was always responsive. He kept us informed of the progress at the home with photos and narrative that was very helpful in expectation setting. Overall we were very happy working with Jonathan and would happily work with him again for a big home construction or flip in the future. We are so happy with the results of the work. A+"

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.
