Unica, a prominent technical service provider backed by Triton Partners, announces the acquisition of Wassink Installatie, a family-owned installation company with operations in Winterswijk and Doetinchem. The deal, announced on November 12, 2026, aims to strengthen Unica’s position in the Oost-Nederland region by expanding its capacity for technical installation projects.
Wassink Installatie, established in 1913, employs approximately 100 people and reports an annual turnover of about €29 million. The company will continue to operate under its own name as part of the Unica group, preserving its brand identity and customer relationships.
Wassink has built a strong reputation as a total installer in the Achterhoek and surrounding areas, offering a comprehensive range of technical services. Its expertise spans advisory, design, realization, management, and maintenance of installations, primarily serving sectors such as utility construction, healthcare, and project-based residential building.
Jilko Andringa, CEO of Unica, highlights the strategic value of the acquisition: “Wassink is a healthy and successful family business with a strong regional presence. This acquisition enhances our footprint in Oost-Nederland and supports the growth of our medium-sized project activities. We share similar values and culture, which provides a solid foundation for future development.”
Wassink’s leadership remains intact, with Derk Wassink as general director and Anne Wassink as financial director, both representing the fourth generation of family management. They will continue to lead the company alongside technical director Vincent Dahlhaus.
The acquisition aligns with Unica’s broader growth strategy, which includes targeted acquisitions to strengthen regional networks and deepen technical expertise. Wassink is the third acquisition by Unica in 2026, following the purchases of Nijmeijer Koeltechniek, Schoonebeek Klimaattechniek, and Van der Laan.
By integrating Wassink, Unica aims to leverage cross-selling opportunities, expand its project portfolio in East Netherlands, and optimize operational efficiencies through shared resources and expertise. The combined entity is expected to enhance service offerings, particularly in medium-sized installation projects for professional clients.
Derk Wassink emphasizes the benefits of joining Unica: “To remain successful and seize new opportunities, partnering with a larger organization was a logical step. Unica shares our values and offers the resources to further develop our business while maintaining our identity and close customer relationships.”
The acquisition also responds to industry challenges such as increasing technical complexity, labor market constraints, and rising demand for sustainable solutions, where scale and specialist knowledge are critical.
Unica plans to maintain Wassink’s operational independence while integrating project management and execution capabilities to streamline regional operations. The company expects regulatory approvals to proceed smoothly and anticipates a seamless transition.
Looking ahead, Unica aims to continue its acquisition-driven growth, reinforcing its position as a leading technical services provider in the Netherlands and expanding its service portfolio to meet evolving market demands.
