"My pro Sal was very efficient in clearing manifold problems. He was patient in listening when I was trying to explain the problems that I was having. I had made a list and we went through all of the conditions that were giving me grief. After a system reboot something strange having to do with the font occurred. I called Sal and he worked remotely going through changes that had been made. The problem was finally resolved. I was very pleased with Sal's ability to decipher what this layman (laywoman) was trying to say. If I have problems in the future, I will contact Sal."

"James, the owner came out for me on a Saturday after my power was restored, but only to half of my house. Within minutes he found it was the GFI in my bathroom that would not reset causing the rest of the house not to come on. Could not be happier with the service."

Founded in 1989 by Dean Henninger, D.W. Henninger Construction has been recognized as a leading builder of custom homes and remodeling projects. Acting as a General Contractor, the entire Henninger team is known to exceed client expectations, leading to a steady stream of testimonials and referral clients.\n\nOver the past two decades, Henninger has managed projects in California: kitchens, bathrooms, room additions, entire home renovation, even complete construction of homes. Regardless of scope, Henninger approaches each project with the same foundation of principals: strong design aesthetics, comprehensive product options, sound project management, and a commitment to craftsmanship.\n\nDesign Aesthetics: With 20+ years of Bay Area experience, Henninger understands the many architectural quirks unique to Bay Area communities, making it easy to elaborate and integrate with established design aesthetics.\nProduct Options: Henninger is truly unique in being a single-source stop for design, remodeling, and product resources. Cabinetry, countertops, appliances, and plumbing fixtures are all available options for your project, and Henninger assists with selection, delivery, even vendor communication if there’s a problem.\nProject Management: Project management is essential to delivering a good customer experience. Henninger prioritizes project management to the same degree as design and crafting. Henninger is unique in using progress billing — a system that only charges for services following completion rather than pre-paying weeks or months before it starts.\nCraftsmanship: Henninger’s team of carpenters bring the best combination of experience and expertise to the table, but they offer much more than technical proficiency — by working with true craftsmen, Henninger projects balance design and functionality for maximum results on each and every project, regardless of scope.\nOur service areas: Oakland, Pleasanton, Livermore, Walnut Creek, Fremont, and surrounding cities. Projects in San Francisco and San Jose are also feasible — contact us for more information.
