Jason Dalk is owner of JD Building.

JD Building provides a complete range of construction services for residential, commercial and government clients in Sonoma, Marin, and Napa Counties. As a design/build firm, the company has the training and equipment to handle every step of its customers’ remodeling, addition and new construction projects, including foundation work, deck and fence building, tile and hardwood floor installation, and more.

Owner Jason Dalk credits much of JD Building’s success to its ability to listen closely to its clients and provide them with exactly what they want. “Since we do all the designing ourselves, we have a better knowledge of what it will cost to complete projects on time and on budget,” he explains. “We always give our clients plenty of options, too. That way, we can go back and forth to get the end result as close to their original vision as possible.”

JD Building emphasizes consistent communication throughout every step of the construction process, from sending emails that detail work progress to providing onsite visits from Mr. Dalk himself. “We keep in touch with our clients in the ways that make them feel most comfortable,” he says. “Whether it’s through email, text, phone calls or in-person meetings, we keep them updated on everything we do.”

Company Philosophy

“Our goal is to provide results that improve each client’s quality of life and give them the best possible value. We’re here to serve our customers and make their lives better, and we accomplish that by showing up on time, staying within budget, and keeping our promises.”
