"The team at High Class Builders & Remodeling Inc were awesome to work with. We were lucky to meet them just before Covid-19 and are so happy. They were able to walk us through the entire process after a dishwasher leaked and ruined our kitchen. They handled our remodel from start to finish! Very much appreciate their efforts. They worked closely with our Insurance company to ensure that everything was covered. Highly professional and through. Responsive to calls and texts. :) During a sensitive time period, I'll always remember that."

"Service was amazing thank you earl and fast water heater my family and I appreciate it"

"Everything went great, I had no problems reaching the office by phone and they were quick to schedule me. Carlos took care of everything just as needed. I would call on them again for plumbing help."

"The work took a little over one hour for two workers. They used a hydro jet on a trailer towed behind their truck. So they had the right tools for the job. They were courteous and efficient. It was not cheap, at nearly $1000. But yes, I would hire them again."

"Five stars, without question. I recently had Cabrillo install a full HVAC system and a new water heater, and the experience was exceptional from start to finish. Erik Ortega, Erik G., and Javier G. were the crew on the job, and these guys are the real deal. They showed up on time, were incredibly professional, and clearly take pride in their work. The installation was done cleanly and efficiently — no mess left behind, no corners cut. They walked me through everything: how the system operates, what to watch for, and how to get the most out of it. No rushed explanations, no impatience with questions. Just solid, honest communication. The quality of the work speaks for itself. The HVAC system is running perfectly, and the new water heater was a seamless upgrade. I was especially impressed by how tidy the whole job was — you'd barely know they'd been there except that everything now works better than ever.
