Why the Bay Area Chooses Gadi Construction
The GADI Team worked with us in multiple renovation projects. They quickly scoped and executed the project within the budget. Job well done!
Inon and his Team do a very good job at defining the work scope and quickly executing to get the work done. They handle all the permitting and the needed inspections as well. We leveraged the Team for multiple renovations. Job well done!
Beautiful job updating the kitchen and shower. Our project manager, Eden was responsive and quickly moved the project along, completing everything in three weeks .
GADI did a great job updating our kitchen and shower.
Our project manager Eden was highly responsive, quickly understood exactly what we needed, and kept everything moving efficiently. The entire project was completed in just 3 weeks. Updating the kitchen included installing a new counter, a new sink, and a built-in dishwasher, and everything is beautiful and working well. They also painted the cabinet doors, greatly improving the look of the kitchen. For the bathroom, they removed a built-in bench, making the shower much more spacious, and beautifully replaced with new tiles, including the floor.
We just completed a full primary bathroom remodel with Gadi constructions and we could not be happier with the result. The quality of the work was excellent, the project was well managed, and the finished bathroom turned out beautifully and almost exactly to the vision I had in mind.
I especially want to recognize Millie, our program manager, who was exceptional from start to finish. Her enthusiasm for her work is infectious, but what impressed me most was how personally invested she became in getting every detail right. She approached the project as though she were working on her own bathroom, not a client’s. She was constantly thinking ahead, finding creative solutions, making things work when challenges came up, and never settling for “good enough.”
I traveled quite a bit during the remodel, and knowing Millie was overseeing everything gave me tremendous peace of mind. She kept the project moving, handled issues without creating unnecessary stress for me, and always made me feel that the details were in very capable hands.
Remodeling can be disruptive and stressful, but having someone who genuinely cares about the outcome makes all the difference. Millie went above and beyond in every sense, and the entire team delivered a bathroom we absolutely love. I would highly recommend them.
