They remodeled my kitchen and built a small addition of a bedroom and a bath. I'm very happy with their work, entire crew was responsive and very professional. Jay, Daniel, Emilio and everybody else did excellent work. I wouldn't hesitate to hire this company for all of my future projects. > > Thank you, from our entire family. **Comment from BuildingCa:** > Thank you for being our customer, it was our pleasure working with you, ### All 13 reviews **★★★★★ — uttara sampath, July 2025** > Building CA recently remodeled our Master Bath. We had a bathroom leak and had to remodel the entire bathroom. We are very pleased with the results. Right from the beginning Jay was extremely responsive and gave us very good suggestions for our project. He understood our budget constraints and was very easy to work with to understand what we could do within our budget. We love the outcome. His crew was coming on a rotating basis but towards the end Santos and Isabel (not sure if i spelled that right) were super diligent and worked late hours to get the project completed on time. They even spent a whole day cleaning up after themselves! They were super responsive and their final work quality was really clean and well executed. We are considering doing our guest bathroom and would unhesitatingly hire Jay and his crew again for this and other projects. **★★★★★ — Anna Stoma, Nov. 2018** > hired Jay to remodel my house in Sunset, every day for 2 months, his > guys were here at 8 am sharp. They worked on my Bathroom and garage, they guided me every step of the way, helped me purchase materials and dealt with the city permits. Im very thankful for their services, they are truly a great group of people. **Comment from BuildingCa:** > Thank you for being our customer, it was our pleasure working with you, **★★★★★ — HU-490990685, Nov. 2018** > Green Star, just finished remodeling my house in Oakland Hills. They built second story addition of about 400 sqf, and remodeled my kitchen. As you can imagine the work was quite extensive and involved some serious structural changes. After about 5 months of work, the job is completed and I couldn't be happier. > I would give these guys 10 stars If I could. All challenges and change orders, were appropriately addressed in timely manner, with the highest level of professionalism. These guys know what they are doing, I was impressed by the level of detailed management starting from the owner of the company Jay, to the project managers Emilio and quality assurance people, to the companies foreman and the rest of the workers. Keep it up guys. I'm sure we will work together again in the future. Thank you. **Comment from BuildingCa:** > Thank you for being our customer, it was our pleasure working with you, **★★★★★ — HU-222920981, Oct. 2018** > Great company to work with. Did my kitchen remodel with them in Palo alto. They did great work and i would definitely hire them again. **Comment from BuildingCa:** > Thank you for being our customer, it was our pleasure working with you, **★★★★★ — HU-486410898, Sept. 2018** > I'm a real estate investor in the bay area for the last 10 years, I've worked with various of different contractors in the past. Green Star is nothing like any of those companies, and I mean it in a good way. Jay and Green Star Construction did absolutely everything they promised to do, came to work at 8 am sharp, passed all inspections on the first try. I was so impressed, I feel that this review is the least that I can do. Honestly, any one who thinks about hiring this company, you can't go wrong. Obviously I'm going to continue working with them, and they already booked my next project ( major structural remodel) to start in November. > > Thank you guys. Your work is appreciated. **Comment from BuildingCa:** > Thank you for being our customer, it was our pleasure working with you, **★★★★★ — Dasha Markman, March 2018** > I found Green star construction online and decided to get an estimate. > After meeting Jay, I decided to hire him and green star construction to remodel my Kitchen. > Now 4 weeks after the start date, the final inspection passed, and I couldn't be happier. Jay helped me sourcing out the materials and guided me throughout the entire project. His company isn't big, which I think is a big advantage since you get personal attention. They were very detail oriented and very professional. If you consider hiring Greenstar construction, do it without thinking twice these guys are awesome. **Comment from BuildingCa:** > Thank you Dasha, We enjoyed working with you on your beautiful home. **★★★★★ — Yvonne Walsh, March 2018** > Jay and his team were very professional. The project was our main bathroom, they turned the shower over tub combo into a stand alone tub & shower by removing a cupboard. They did the tile work, the crown molding, construction of the shower from scratch installations of vanity, toilet, recess lighting, vanity lights, fan, sun tunnel and accessories (toilet holder, medicine cabinet etc) Everything was done in house by the team except the glass which they organized the measurement and installation. They were very respectful of my home, vacuumed everyday and kept the mess at a minimum. Every morning they were prompt starting at 8 and left at 4/5 sometimes 6. I was impressed by the speed & quality of the job. > > We are undertaking a remodel/addition for the rest of my house and they will also be doing that work for us as we were happy with the service provided. **Comment from BuildingCa:** > Thank you, We enjoyed working with you. The results were amazing. **★★★★★ — Banu Radhi, March 2018** > We found GreenStar Construction online, and scheduled a visit with their representative. > We liked that within an hour from our phone call, Jay the owner was able to come out and provide us with an estimate. We discussed different remodeling ideas, and we had a good impression of his knowledge. We appreciated that there was no pressure for us to sign right away, we liked the design ideas and we really liked the reasonable price Jay provided us for 2 bathrooms > In the beginning we felt overwhelmed with all the different options for materials, Jay directed us and guided us through out the project, helped us sourcing out the materials and followed through with his promises. > Initially we were worried about the outcome of installing small marble tiles on the wall since we were not sure about how it'll look at the end, but the crew was very professional, installed small subway marble tile on the wall, they made sure the tile was straight, they polished the edges and made it look very nice. By end of each they the crew updated us about the work that was done and the work that will be done in the following days. We are very pleased with Green Stars work, and we will recommend them to our friends and neighbors **Comment from BuildingCa:** > Thank you, We appreciate the business and the refferals to your Family members and friends. **★★★★★ — gal nunu, Dec. 2017** > GreenStar Construction did great job remodeling my kitchen and bath, Jay made sure we are aware of all pitfalls and hiccups that may occur and was very straight forward with his approach regarding the remodel. > The end result was great me and my fiancé love our new kitchen and bathroom. I like how this company operates and I’m for sure going to use their services again. **Comment from BuildingCa:** > Thank you, We appreciate the business and the refferals to your Family members and friends. **★★★★★ — Kamyar Joon, Dec. 2017** > Great company, Great service, Very professional, They finished my bathroom and they did an outstanding job. > > Their work worth more than what they charge. > > I will use them again, and I recommend them to all friends and family. > > Thank you Jay for your perfect Job. **Comment from BuildingCa:** > Thank you, We appreciate the business and the refferals to your Family members and friends. **★★★★★ — Marina Motornaya, Nov. 2017** > I heard about Green Star Construction from various people, seemed most of whom I talked to were very satisfied with their work. > Now after they finished remodelling my property I can confirm, this company is legitimate, their workmanship is great, very very detail oriented and professional. > Highly recommended **Comment from BuildingCa:** > Thank you, We appreciate the business and the refferals to your Family members and friends. **★★★★★ — Greg Edwards, April 2017** > I found GreenStar Construction through word of mouth. I was impressed by the designs my colleague showed me with such a substantial budget on their home, so my wife and I decided to go with them. We were re-designing our kitchen. We changed countertops, sinks, backsplash and cabinets. The owner gave us phenomenal options to choose from within our budget. Jay has an eye for design which my wife really appreciated. He always answered our calls, answered all of our questions, and went up and beyond to make sure we stayed within our budget and were satisfied. Thanks Jay, my wife loves her new kitchen. **Comment from BuildingCa:** > Mr Edwards, > > Thank you very much for choosing our company for your remodel, > it was pleasure working with you on your lovely home, we hope you will consider us for all of your future remodeling projects. > > thank you. > GreenStar Family ## Selected projects - [Lafayette Home Renovation](https://www.houzz.com/hznb/projects/lafayette-home-renovation-pj-vj~7617205) - Location: Not specified - Photos: 23 - Description: Complete Home Renovation: Modern Luxury Meets Timeless Design This comprehensive home renovation reimagined every inch of this 5-bedroom, 4.5-bath, 4,250 sq. ft. property, blending modern luxury with functionality.
