About Us
A family-owned contractor with three generations of craftsmanship.
For more than 30 years, United Constructors Inc. has been transforming homes across Contra Costa County and the SF Bay Area — one custom kitchen, bath, and addition at a time.
Our Story
Built by hand, passed down by family.
United Constructors Inc. started as a small two-man shop more than three decades ago — a father and son working out of a single pickup truck, building one remodel at a time across Alamo and Walnut Creek.
Today we're a full-service residential and commercial contractor with in-house carpenters, electricians, painters and project managers — but we still answer the phone ourselves, still walk every job site, and still hand each finished home off to the homeowner like it was our own.
The third generation now leads daily operations, carrying the same commitment to craftsmanship that has earned UCI hundreds of 5-star reviews across the Bay Area.
Our Motto
"Build it the way you'd want it built in your own home."
