    "I did a kitchen remodel in 2010 with Golan remodeling. I just started reviewing companies. I really enjoyed the entire experience with this company it is a very small company but they do extreme remodels. I hired them again in 2012 to do a bathroom remodel and I received the same amazing service as I did in 2010. Very knowledgeable staff very clean and professional and very trustworthy. I was never home they had a key and nothing went missing. I know they will be my number one contractor as long as I do remodels. I highly recommend."

    "I had such a positive experience with California Designers Remodeling! Ray Vanunu and his team were exceptional. They were always on time, professional, and took care to ensure the work was done right. Ray’s expertise really shone through during the design phase—he helped us create a layout that’s both beautiful and functional. The project was completed within the promised timeline, and the attention to detail was incredible.

    "I have worked with several contractors in the past and by far, Rudimental was the best... by a longshot! From the time they first came out to look at my house, they took the time to walk through it and listened to my wishlist of stuff to get done, and gave me the confidence that this would get done properly. This was a near 7 figure remodel of my home, which touched almost every part of the house. They worked hand in hand with my architect & designer and made the whole process completely seamless. I've had friends that had their construction projects fly off the rails, and even had a project in the past go very poorly, so I was very skeptical. But Paymon and his team were top notch. They kept me up to speed every step of the way, hit timelines, and managed the budget perfectly. Wilton was our project manager and he was excellent. He was at the house very often and kept everything running smoothly. I would stop in once a week to check on progress, and they always were there doing work and keeping things going. No messes, no random trash laying around, and just high quality, meticulous attention to detail. We've been back in our place for 3 months now, and everything is perfect. I can't recommend these guys enough. If you have a project that requires high quality cratsmanship, look no further than Rudimental. They came highly recommended from a friend, and I can't thank them enough for making the referral. And thanks to Paymon, Wilton, and the team for the very best work I could've asked for!"

He was incredibly thoughtful and patient with every detail and decision, always willing to discuss alternatives, and never was satisfied until the work was perfect. He was a great communicator and there were never any surprises. He delivered an ADU above our expectations - on time and under budget, something nearly unheard of in the construction world! I also really appreciated his design sense and suggestions - he has excellent taste and judgement. If you are considering hiring a contractor, look no further - trust me on this one and hire Sklar Construction. I can promise you that you will not regret it."

The owner Steven Davis was available for us every single time we called with questions regardless of the time of day. He was on site supervising and ensured we got everything we asked for. In some cases we messed up by not ordering enough supplies and he graciously solved the issue for us and did not add additional fees. We remodeled our office Break Room and the employees are all thrilled with the new space. Great work and great overall experience.

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.
