Q: What are clients of Diamond Certified remodeling contractors saying about contractors in Castro Valley, CA?
A: Verified Green Living Builders LLC Customer, 1 of 133 "Rolf is very experienced and thorough. He has good communication which is important and rare with contractors. He does a good job on time and on budget. We recommend them. I like everything about them. They are rare contractors that are responsive and communicative. They are the best. " - Ana F. All Survey Responses for Green Living Builders LLC Verified Today's Kitchen & Bath Customer, 1 of 51 "What I would say if there were concerns or changes needed is that they would address it quickly. While I was at work, the tile was placed in the kitchen. When I came home, I noticed that the stone store gave me the wrong tiles. Today's Kitchen & Bath removed it and worked with the stone store. Additionally, over nine months after my job was complete, my dishwasher was giving codes, so I called Today Kitchen & Bath and they promptly sent someone out to look at the connecting pieces. They go the extra mile for customer service. The ability to easily get in touch with the team, whenever I had a question, it was answered and followed up on. The process of design and picking out material was stressful to me. They were able to walk me through each step and ease the unknowns for me." - Jenell K. All Survey Responses for Today's Kitchen & Bath Verified Advance Construction Customer, 1 of 75 "The main thing that I liked about Advance Construction was that Michael was easy to work with. I have seen a lot of contractors that know what they're doing, but they are not all easy to work with, and Michael was. I think what I liked best about it was that he was flexible and accommodating. I tried not to make changes, but there's always one thing that needs to be changed, and Michael was able to come back without trouble or any added extra expense to fix it. They weren't big things. He was definitely accommodating about that. " - Mark S. All Survey Responses for Advance Construction Verified Ingenious General Construction Customer, 1 of 10 "They are a very professional company with a ton of expertise in construction. They were very helpful in answering my questions while also providing a reasonable quote. The project manager was responsive to the workers and always came on time to the work site. They were respectful of my space by cleaning up and gave me regular updates on what they would be working on next They had great communication, which is essential to any work like this. They were very detail oriented when it came to design, planning and building." - Ambreen H. All Survey Responses for Ingenious General Construction Verified Smith & Son Construction Customer, 1 of 10 "They are very professional and detailed. The crew is wonderful to work with and they are always willing to help us find different avenues. They are always very resourceful and they are great about being safe. They are going to look at a roof in one of our yards and we could have done patch work on it, but that would be a band-aid. They wanted to make sure that everything was safe and up to code. Previous work they had done for us, they were very detailed about things they had found and repaired. The whole process was professional and very thorough. I love their professional work and their detailed solution. The crew is very personable and great to work with." - Taylor M. All Survey Responses for Smith & Son Construction Verified Rockridge Builders Customer, 1 of 75 "They did the job better than I was expecting. One thing I liked a lot is the fact that they were safe while on the job. I thought they were competent, conscientious, and informative. I felt like they really knew what they were doing and not just winging it." - Ann B. All Survey Responses for Rockridge Builders
