About Frank Silha & Sons Excavation

Since the 1950s, Frank Silha & Sons Excavating has served Southern Wisconsin customers with integrity and dedication.

Company founder Frank Silha, a Janesville resident and 13-year employee of General Motors, saw a need for quality excavation services in Southern Wisconsin. He began Frank Silha & Sons Excavating with just a few pieces of equipment and a grand vision for the future founded on dependable, quality service.

Committed to Innovation from the Start

In the early days, it wasn't uncommon to see Frank stripping topsoil from job sites with a snowplow and a jeep. But Frank was an innovator from the very beginning. In the 1960s, it was common practice to use a track loader for foundation excavation. Frank, always looking for a better way to use the latest technology, began using backhoes to dig basements. Following his example, it wasn’t long before backhoes replaced the track loader in Southern Wisconsin. Frank was a pioneer in the field of earth moving, who brought his spirit of innovation to every project the company undertook.

Expanding to Meet Customer Needs

In 1964, Frank added his first employee. By the 1970s, Silha Excavating had grown into one of the premier excavation companies in Southern Wisconsin. Silha & Sons was hired to do the excavation work at the rapidly expanding Janesville General Motors plant on multiple occasions throughout the 1960s, 1970s and early 1980s. Large jobs of all kinds—from warehouse and factory expansions to city, county and state work—soon followed. Today, Frank Silha & Sons Excavating is a regional industry-leader, well known for its wide range of equipment, commitment to leading-edge technology and exceptional work.
