Client Testimonials

Our experience with Golden Shore Design and Build was absolutely delightful. We waited 27 years to enhance our kitchen, and it was due for a makeover. Petra, Alex, Rocky and team lead us every step of the way, and were great to work with in every aspect. We could not have hoped for a more professional, knowledgeable group...

Their work is exceptional and theyre great people to work with. When others told us that our ideas to remodel our bathroom were unaffordable, and found a way. They answered our questions, took us to their suppliers, and gave us their discounts. And although they brought in a team of experienced craftsmen to do the work, they were on top of things every step of the way. Lots of contractors make promises; Golden Shore delivers. Contact them firstor lastbut do contact thembecause youll end up hiring them. And when the job is done, youll be very happy that Golden Shore did it.

We hired Golden Shore Design & Build to remodel our kitchen in Coronado Island. We heard about them from a friend who they did his own kitchen a few months back. Our old kitchen was more than 20 years old so we needed a complete remodel. Everything was done perfectly!

Alex and Petra made the rebuilding of our bathroom a wonderful experience! We met with them several times to decide on design and materials and they were incredibly helpful, insightful, and enthusiastic about getting us exactly what we wanted. Although our budget was tight, they were able to help us choose materials that look incredible.
Natalie Thompson
We hired Golden Shore Design and Build for bathroom addition to the main house and detached 2-bedroom 1-bathroom ADU. The whole crew was professional, worked well together as a team and committed to the project from start to finish. There was good work consistency and communication. The team addressed every question/concern we had, did extra effort and work to accommodate changes and corrections to the existing plans which resulted to a beautiful master bath and detached ADU. Thank you GSDB for helping us make our project a success!
