Q: What are clients of Diamond Certified solar system cleaners saying about companies in Castro Valley, CA?
A: Verified Sierra Roofing & Solar Customer, 1 of 323 "The job I selected was spray on all continuous film on a flat roof that wasn't a commercial building. I went walking on the roof to check out the job and noticed that some areas of the roof are hidden by some walls so near there, some areas hadn't been done. I called them to let them know and they immediately came over and corrected the problem. I'm satisfied. The courtesy they have for the customer and they explain everything pretty nicely. When they came back so I could sign the contract, I wanted a change, and they changed it so they were flexible." - John O. All Survey Responses for Sierra Roofing & Solar Verified Got Watts Electric, Solar & HVAC Customer, 1 of 415 "They are a little pricier than most, but you only have to have it done once. They use up-to-code industry standards. I trust that they are going to do everything correct the first time. I think they are super friendly, and they always fit me into the schedule. I like that it will get done right the first time. They fixed many things that were done wrong in the past by other people as well. I use them all the time now. " - Jessica L. All Survey Responses for Got Watts Electric, Solar & HVAC Verified High Definition Solar Customer, 1 of 250 "I like the fact they did both roofing and solar. They have to do them together, if you ever have looked into the solar, you will notice companies will recommend this.
Because I'm very picky about what I have done to my home, they were tolerant of this fact and didn't mind me watching them closely. They had a good plan and are very organized." - Peter G. All Survey Responses for High Definition Solar
