Client Testimonials
“We went through two contractors over seven years trying to remodel our 7,000 sqft historic family home in Alameda. Nothing moved forward until a family friend referred us to Sturdy Home Builders. Stephen and Sam were responsive, transparent, and took real ownership of the work. The project had highly specialized requirements and they helped us source the majority of the materials. My dad and I truly appreciated their commitment and will definitely be working with them again.”

“Worked with Sam on 2 large remodels and additions. The first one was for an ADU and house remodel. I interviewed over 9 contractors and I’m very happy I went with Sam. Very clear and straightforward from the start. Easy to communicate with to make sure things are done to what I expect. Shortly after completing the first project, we worked together on another full house remodel and adding extra sqft. Finished in the agreed amount of time. Sam stands behind his work and doesn’t the work right the first time. Will be working with Sam again when I find my next project.”

“We have worked on several projects with Sturdy Home Builders in the last four years. We plan on continuing to do so because they are great communicators, careful and thoughtful, and have been the most timely contractors we have ever worked with. We collaborated every step of the way for all of our projects, and they are always open to our opinions, ideas, and feedback. We are constantly referring friends and family to Sturdy Home Builders and will continue to do so!”

“My husband and I are very happy with our bathroom renovation working with Sturdy Home Builders. We were particular and specific with our bathroom design and SHB was open and collaborative with the process. SHB provided us invaluable suggestions when needed based on their many years of experience and expertise which we appreciated the input to avoid any potential ‘redo’s’. The crew were professional, hardworking and left the staging area very clean at the end of each workday. We were pleased with the construction/communication processes with the project.”
