Frequently Asked Questions for Contractor - Design & Build in Castro Valley, CA
Q: What are clients of Diamond Certified design/build contractors saying about contractors in Castro Valley, CA?
A: Verified Bliss Design Build Customer, 1 of 10 "High quality work, attention to detail, and something that is rare is good communication with the work crew, the foreman is excellent. They are unlike most construction people. They make sure things are cleaned up as best as possible. I guess attention to detail, and no matter what was going on, they were able to help me. If it was something that needed to be dealt with, there was always a quick resolution." - Jeff S. All Survey Responses for Bliss Design Build Verified Dream Build Services Customer, 1 of 10 "They were honest and worked well off of the ideas I had. They let me know when something wasn't possible and offered good alternatives. Just what I said, those were the best things." - Austin V. All Survey Responses for Dream Build Services Verified Home Healing Renovations, Inc. Customer, 1 of 96 "They were on time with deadlines and very clear and descriptive about the scope of work they were doing on the property. They paid close attention to detail, and I thought the most important thing, since you hear a lot of horror stories about contractors, is that they were on time and they got it done when they said they would. The pricing was fair, and the workmanship was very good. I also found after completion that if I wanted something touched up or had a little issue, they were very quick to come out and make the change or fix whatever it was. It's easy to contact someone. I had no issues at all. I really like them. They were able to deliver what it is that I wanted. They were very quick with sending photos of ideas and concepts that I might like to make sure we were on the same page design-wise. They were very accommodating, and there was never any argument. There were little things like maybe I wanted the crown molding painted with a little higher gloss than the original, and they completed it with no complaints. They were detail oriented, and we all stayed on the same page throughout the entire process. I felt as far as contractors go, they're beyond other contractors I've dealt with before. I think the reason why it flows so well is that Jason stays on top of everything. If there's an issue he'll come to the job." - Paula B. All Survey Responses for Home Healing Renovations, Inc.
