"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. Our new kitchen has become the heart of our home, and we’re so grateful to Ray and his team for making it happen!"

"I truly could not recommend Danny any higher. From the moment we began working with him, he was honest, reliable and just a total pleasure to work with. 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."

"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!"

"Efrain and David are fantastic! When our contractor was suddenly unable to continue with the job, David took over with a great positive attitude. He persistently worked with the city to get the building permit, finally ending a tedious 10 month process. Crews were here working every day. Each one of them was considerate, conscientious, and demonstrated a strong work ethic. Efrain and David communicated with us most days and were always accessible to us. My ADU is adorable and just what we wanted and I am sure that many contractors could have pulled it off. The important thing about Olalde is that they truly care and honestly want us to be happy."

I can talk and talk - end of day - go hire them and see for yourself. This is my contractor from now on."

"Amazing is the best way to describe the service and work quality we got from Far Hill Construction. 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. Will absolutely be calling Far Hill Construction for any future projects that may come about."

"We suffered a major leak last year, causing an immediate need to remodel our kitchen. We interviewed six general contractors prior to making our selection, asking nearly every question we could think of to ensure we made the right choice. From the very first meeting, we knew Elron and his company was the right fit for us. Whereas each of the other 5 candidates gave various (sometimes opposing) solutions for the soffit in our kitchen, Elron was the first to get his hands dirty to find out what was feasible and cost-effective. He was a straight-shooter, set proper expectations and followed through during the entirety of our project. His subcontractors were all top notch and worked hard to ensure we were happy with the final product. Our entire kitchen remodel took 5 weeks from start to finish (including Christmas and New Years). The teams were clean, courteous, and detailed. Jordan was a great help on the design aspect of the project. She joined us on our shopping trips to find countertops, flooring, and backsplash and provided helpful recommendations for hardware and other finishing touches. Her eye for design was spot on and her connections in the trade made the entire process so much easier than had we tried to wade through on our own. We love our new kitchen and had a great experience with Beverly Builders Group. We highly recommend them to anyone looking for high quality home renovations and plan to use them again in the future for our next set of projects."

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.
