Cube Construction Inc

At Cube Construction Inc, we turn renovation ideas into reality with precision, craftsmanship, and integrity.

Built on more than a decade of hands-on construction experience in California’s Bay Area, our company is one of the few general contractors fully licensed across four CSLB classifications — A (General Engineering), B (General Building), C-10 (Electrical), and C-36 (Plumbing). We are fully insured, DIR-registered for California public works, and BBB Accredited with an A+ rating.

We handle a wide range of residential and commercial projects, from ADUs and full home remodels to kitchen and bathroom renovations, electrical and plumbing upgrades, siding, and concrete work. Because we hold our own electrical and plumbing licenses in-house, our clients get tighter coordination, fewer subcontractor delays, and a single point of accountability from start to finish.

Our team combines strong technical expertise with professional project management to ensure every job is completed on time, within budget, and to a standard we’d be proud to put our name on. We take pride in transparent communication, attention to detail, and treating every home like it’s our own.

Whether you’re planning a simple upgrade or a complete transformation, Cube Construction Inc is your trusted partner for turnkey remodeling solutions across San Jose, Santa Clara, Sunnyvale, Campbell, Los Gatos, Palo Alto, and Fremont.
