About Yellow Hat ConstructionExperienced hands.
Experienced hands.
One accountable team.
Yellow Hat was founded to make remodeling more straightforward: listen carefully, plan the work, communicate clearly, and finish with the details handled.
The story
Construction experience that started long before the logo.
Ahmad Mohammadi began in construction in 2004. Yellow Hat Construction Inc. became a California corporation and licensed contractor in 2023, building on two decades of hands-on project experience.
Today, a ten-person in-house team operates as five two-person crews. That structure keeps ownership of the work close to the people doing it and makes it easier to coordinate the sequence from demolition through final details.
While the company has broad remodeling experience, Yellow Hat’s primary consumer focus is bathroom work—especially wet-area transformations and complete bathroom remodels.
