Robert & Sons Fontana Builders

Robert & Sons Fontana Builders is a family-owned and operated general contracting company proudly serving Fontana, CA and the wider Inland Empire community. Based right here on Sierra Ave. in Fontana, we understand the unique character of our neighborhoods, the local climate demands on homes, and the expectations of homeowners across communities like Rancho Cucamonga, Rialto, Colton, Upland, Ontario, and beyond.

What started as a passion for craftsmanship and a dedication to honest work has grown into a full-service home improvement company capable of handling everything from a fresh kitchen remodel to a complete accessory dwelling unit (ADU) build. Every project we take on—large or small—receives the same level of attention, care, and skilled labor that has built our reputation throughout San Bernardino and Riverside counties.

We believe your home is your most valuable asset, and every renovation decision matters. That's why our team takes the time to listen to your vision, assess your space with a trained eye, and develop a plan that balances quality craftsmanship with realistic budgets and timelines. From the first conversation to the final walk-through, Robert & Sons is with you every step of the way.

We serve homeowners, property investors, and landlords across Fontana, Bloomington, North Fontana, South Fontana, Etiwanda, Cucamonga, Mira Loma, Alta Loma, Grand Terrace, Muscoy, Loma Linda, Highland, Redlands, Montclair, Chino, Chino Hills, Moreno Valley, Claremont, Corona, Pomona, La Verne, San Dimas, Diamond Bar, Norco, and Riverside. If you're in the Inland Empire, we're in your neighborhood.
