Frequently Asked Questions for Contractor - Remodeling & Additions in Antioch, CA
Q: What are clients of Diamond Certified remodeling contractors saying about contractors in Antioch, CA?
A: Verified A Ramos Construction, Inc. Customer, 1 of 47 "I am very happy with their work. They were great. They had different people come out to look at the job and address the challenges that we had. They were all great as well. They were very professional and it actually surprised me how communicative they were. That communication was really helpful for me, because I was an hour and forty minutes away from the property for most of the process, as it is a rental house. They were excellent with keeping me informed and would let me know what was going on or if I had any questions. I had no trouble getting in touch with them. They were thorough, and when we had some questions, they were responsive. They were even easy to reach after the fact when the job was finished. They were great." - Robert L. All Survey Responses for A Ramos Construction, Inc. Verified Dahme Construction Customer, 1 of 12 "They are knowledgeable all around. They are conscious and do good work. They go the extra mile. There is not a lot of people who take pride in their work nowadays, but him and his workers really take pride and are knowledgeable. I could call him at anytime and ask him a question. He immediately knows what needs to be done." - Dan P. All Survey Responses for Dahme Construction Verified Cardinal Builder, Inc Customer, 1 of 157 "I would tell them you're going to get a quality product for a reasonable price. It's more expensive than a general contractor, but you're going to get the quality behind the company. That's what I wanted. I wanted a few things, one is quality, one is a fair price, and the last thing is for them to show up when they said they will and work within the time frame they give and they definitely did that. I like that one of the owners is always on the project, and you can tell they train and use their own people and not subcontractors. As a single woman that means a lot to me. They have great people relations, they showed up, and they did everything I expected." - Suzanne H. All Survey Responses for Cardinal Builder, Inc Verified Gar-Cal Corporation Customer, 1 of 48 "I have used Gar-Cal on 5 jobs so far. After the second job they did for me, I decided that I will only hire Gar-Cal. I trust their commitment to my satisfaction. The quality of work and attention to detail is excellent. I appreciate the open collaboration with the owner, Angel Garcia. He's very flexible, asks questions about what I want and provides excellent suggestions. He is my trusted advisor. Their concern for me and my home, during the second job, one worker noticed a water leak at my main valve. He let me know immediately and I contacted Angel, the owner. Angel himself came out soon after and fixed the leak himself. He asked me how I wanted it taken care of and I told him to fix it as if it was his own. He did a great job, came at a moments notice and took care of it before it became an issue for my family. He gave me a reasonable price afterwards and asked if it was okay. I completely trust their honesty, integrity and quality" - Jeff H. All Survey Responses for Gar-Cal Corporation 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
