Introduction
Dellarocco Plumbing is a privately held plumbing services and manufacturing company headquartered in the Midwest United States. The firm specializes in residential and commercial pipe installation, repair, and maintenance, and has expanded into the production of custom fittings and valves for the broader plumbing industry. With a workforce that has grown from a handful of technicians in the early 1990s to more than 300 employees in 2025, Dellarocco Plumbing has positioned itself as a regional leader in plumbing solutions. The company is known for its emphasis on sustainable practices, advanced diagnostic technologies, and a customer‑centric service model.
History and Founding
Origins
The origins of Dellarocco Plumbing trace back to 1992, when founder Lorenzo Dellarocco, a former municipal pipe inspector, established a small repair shop in Springfield, Illinois. Lorenzo had accumulated over a decade of experience in municipal infrastructure projects, during which he identified recurring deficiencies in the supply chain for replacement fittings and the lack of localized expertise for emergency pipe repairs. Motivated by these observations, he opened a storefront that offered on‑site repairs, pipe replacements, and basic maintenance services.
Early Expansion
During the late 1990s, the company began to diversify its service offerings. By 1998, Dellarocco Plumbing had added full‑service plumbing installations for new residential developments, capitalizing on a local construction boom. The firm also began producing a limited line of custom threaded fittings designed for complex commercial installations, marking its first foray into manufacturing.
Corporate Structuring
In 2003, the company incorporated as Dellarocco Plumbing, Inc. to formalize its operations and attract additional capital. This corporate restructuring allowed the firm to acquire a fleet of service trucks, hire additional certified plumbers, and invest in diagnostic equipment such as electronic pipe locators and trenchless inspection cameras. The incorporation also facilitated the creation of a dedicated research and development division that focused on product innovation.
Corporate Structure
Ownership
Dellarocco Plumbing remains under the ownership of the Dellarocco family. Lorenzo Dellarocco retained majority ownership following the 2003 incorporation, and his sons, Marco and Elena, joined the executive team in 2010 as the company expanded. The family’s continued involvement has fostered a corporate culture that emphasizes long‑term relationships with both clients and suppliers.
Management
The current executive team is led by Chief Executive Officer Marco Dellarocco, who oversees operations, finance, and strategic development. The Chief Operating Officer, Elena Dellarocco, manages field operations and service delivery, while a Chief Technology Officer heads the product development and quality assurance functions. The board of directors consists of family members and independent industry experts.

While headquartered in Springfield, Illinois, Dellarocco Plumbing’s service area covers the entire state of Illinois, parts of Indiana, Missouri, and Kentucky. The company operates a regional distribution center in St. Louis, Missouri, which serves as the hub for manufacturing and logistics for the Midwest. Service zones are divided into urban, suburban, and rural clusters to optimize dispatch efficiency and minimize travel time.
