    VALLEY SPRINGS, CA·

    Additions and Remodels, General Contracting

    "John and his team have done many projects for us (shed to fully functioning insulated office, deck, built in shelving, roof etc) and most recently remodeled two bathrooms for me. One was a full hall bath renovation and another was a master bathroom with new configuration and an added a walk in closet. John and his team were on time or early, clean, and very efficient. When all things went according to plan they were even able to finished my hall bath a week early. John was very professional providing us with a contract and a payment schedule matching the progression of each project. His work is beautiful, and his ability to listen to my ideas while informing me of what was able and not in our old home was very helpful. I will be using John again soon to remodel our living room/kitchen layout. I highly recommend John and his team for your next project or projects!"

    "My family and I sold our starter home and purchased an upgrade home during the thick of the Covid 19 pandemic. It was a huge risk but it's turning into a great investment. We spent about 3 months renovating our starter home with our previous contractor. Almost all of the work performed was cosmetic so no extensive amount of work such as stripping an area down to the studs was required. Anyhow, most of our experience with contractors up to that point have been cosmetics. After we've purchased our current home, we realized if we wanted to personalize it, we would have to renovate more than 700 square feet, including a 300 square feet of addition. So, how are we to do this in the midst of a pandemic and an economic recession where the cost of labor and goods are ever rising while we have a modest budget?! The only option was to do some extensive cost comparisons. We ended up talking to 12 contractors and interviewed around 8 companies. We limited our choices down to 2: Creation 7 and a Plan B. We ended up choosing Creation 7 because they made us felt comfortable, confident and excited. On top of that, they were able to commit to our modest budget. After speaking to Eyal, the CEO of Creation 7, we signed the contract and paid the deposit in January 2021. Here's where things took a bit left turn on us. Due to the Covid 19 pandemic persisting throughout, doing a huge renovation of this magnitude was becoming ever more challenging. After many months of permit delays, we finally broke ground in the middle of July. The entire work was completed about 5 months. The scope of the work included: Converting an one car garage to a laundry room, master suite, and completely gut the existing bathroom and build an ensuite, plus removing a continuation wall, door to make room for a den. Oh, forgot to mention the city required us to have an one car garage. So, we had to scramble to make room in the budget for a garage. We also added a tankless electric water heater which resulted in another budget increase for an electrical panel upgrade. After a few incremental budget increases, Creation 7's project manager, Guy was able to work with us to perform the scope of the work and still make it affordable. I could go on and on about our experiences with Creation 7, but I'll save you the time and say this: We absolutely love our new home! After all the headaches and stress, this was definitely a successful project and we will recommend Creation 7 to anyone who is looking to hire contractors. Creation 7 cares about their customers and have led us to believe they will do whatever it is in their power to make them happy. For that, we feel privileged and grateful!!"

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.
