"From the very start I was impressed with the company's knowledge, work ethic, professionalism and dedication to provide a superior, beautiful and cost effective remodeled kitchen. My kitchen had extensive water and mold damage. The kitchen had been stripped to the studs and the mold had been remediated as well as the hot water heater removed before Ron came and gave me and estimate. After hiring his company, the first day on the job they brought and restored hot water to my home. A non functioning kitchen and only cold running water to the rest of the house is brutal. I was so glad that he made that the first priority. Next he showed us a markup of what my kitchen could look like if it met my approval. I was pleased with his design. I valued his ideas and expertise in kitchen design but felt free to share my own design thoughts. He helped me to stay within budget without compromising my design esthetic. Collaboratively, I now have a beautiful, functioning kitchen that I am very proud of. All of the crew from Hernandez Constructon were courteous, respectful, knowledgeable, and professional. I highly recommend their services. I feel as though I now have a contractor for life. Thank you Ron and crew for turning my nightmare into a dream."

"Armando was very professional and did a great job, we were very happy!"

"It was a pleasure to work with Eric, we hired him for a complete backyard renovation which included tree removal, leveling the surface and place pavers and a deck on top. Also built a retaining wall. The work came out very nice in part because of the great design ideas that Eric gave us. The project ran into some unexpected issues that Eric was able to overcome nicely. We were impressed how Eric handled the project and met all the deliverables, also his team was extremely polite an professional. Our backyard now looks like the ones advertised in magazines. All this led us to start a new project with him to replace the cracked driveway with nice new pavers."

"Roberto Sandoval and his company have been doing our landscaping for many years. We’ve always relied on him for honest, reasonably-priced services with excellent care and attention. Absolutely recommend him highly!"

"We hired Shilpa to design an addition and remodel to our existing house in Fremont and we had a wonderful experience working with her. She listened and understood our needs, and designed the house of our dreams in the limited area that we had. She gave us many different design options in the beginning and made many revisions as per our requests. She even helped us with the city permit process and made revisions as per city requirements. The final result turned out beautiful, she used every inch of the space and the addition looks very much part of the original house. I am enjoying my beautiful house and get complements from everyone. I am very happy that I hired Shilpa and her team for my project and would definitely recommend her to others."
