A look at Allstar Plumbing’s fleet of service trucks

company logo

Allstar Plumbing provides a complete range of plumbing services for residential and commercial clients in Santa Clara, San Mateo, and Alameda Counties. In addition to installing, maintaining and repairing all types of plumbing fixtures, the company has the training and equipment to work on sewer lines, repair and replace water heaters, install copper piping, and more.

Manager Steve Schafer says much of Allstar Plumbing’s success can be attributed to its “customer first” business approach. “We strive to give our customers the best possible value, and that includes keeping their homes clean and bringing certain issues to their attention so they can avoid costly repairs in the future. We put our clients’ needs before our own and draw upon our years of experience to ensure their satisfaction.”

Allstar Plumbing sends a fully stocked box truck to every jobsite, which Mr. Schafer says is important for ensuring quick, efficient work. “Our trucks carry more than 400 different parts, which saves our customers time and money because we don’t have to run to the store if we need something. Ultimately, we want them to think of us as a one-stop solution for all their plumbing needs.”
