Building Relationships Since 1985

More than 35 years ago, Mark De Mattei discovered his talent and passion for putting families in the homes of their dreams. Nearly 2,000 happy clients later—many of whom have become our friends and fiercest advocates—De Mattei Construction has become the Bay Area’s premier choice for custom homebuilding and remodeling. We believe custom home and remodeling projects should be joyfully exciting—not overwhelming. That’s why De Mattei takes away the stressful elements of your construction project, with caring experts who guide you every step of the way and fully transparent processes that put you in control of every detail. You can count on knowing that our family isn’t happy with your new home until your family is. The award-winning De Mattei team, now more than 75 strong, prides itself on a tradition of professionalism, transparency, and uncompromising quality. We build more than homes—we build relationships with the people who live in them.
