A recent residential remodeling project by G. D. Enterprise

company logo

G. D. Enterprise provides custom construction and remodeling services for residential clients throughout the San Francisco Peninsula. The company has the in-house capabilities to remodel kitchens and bathrooms, build new homes and room additions, renovate entire houses, and more.

Owner Gregory Danz says his favorite part of the remodeling business is solving the challenges that often arise during custom construction projects. “There aren’t many variables with new construction, but remodeling projects require a lot of shifting and problem solving in order to make the new work blend with the old. That’s the sort of thing that inspires us to go above and beyond our clients’ expectations.”

G. D. Enterprise’s ability to handle most phases of construction in-house (rather than delegating the work to subcontractors) ultimately saves its clients time and money. “We’re more knowledgeable about the different construction trades than most contractors,” says Mr. Danz. “The amount of services we provide in-house really sets us apart from our competition.”

Greg Danz: Unshakeable Roots

By James Florence, Senior Writer

REDWOOD CITY — Heading into college, Greg Danz was determined to transcend his family’s roots in the trades, but he ultimately found them harder to shake than he’d anticipated. “Most of my family is in the trades, including my uncles, who are contractors and electricians,” he explains. “Following high school, I went to college with plans to pursue a different kind of career and ended up studying finance. After graduation, I got into property mana...
