Wassink Installatie

What Wassink Installatie does

Wassink Installatie is a fourth-generation, family-owned mechanical and electrical installation contractor headquartered in Winterswijk, Netherlands, with a second location in Doetinchem and approximately 100+ staff. Founded in 1913 by D.W. Wassink as a blacksmith operation, the company has progressively specialized into a 'totaalinstallateur' (total installer) serving B2B clients exclusively — housing corporations, healthcare/elderly-care operators (e.g., Azora, Marga Klompé, Elver, Markenheem), residential developers and main contractors (KlaassenGroep, Nikkels, Klomps, Optimum Plus), and commercial/industrial owners (Bronkhorst High-Tech, Obelink, Vink Kunststoffen) across Gelderland, Overijssel, and Utrecht. Its core technical scope spans mechanical engineering (heat pumps, HVAC, balanced ventilation, plumbing, sanitary), electrotechnical installations (lighting, fire alarm, security, access control, CCTV, data networks), and KNX building automation, delivered as fully designed-and-built projects rather than individual trade work.

The company's technology platform centers on Klimaatbeheer, a remote climate management service built around third-party building management systems (KNX, Nedap-class platforms) that enables 24/7 monitoring, early fault detection, and remote adjustment of installed building systems. Wassink is brand-agnostic on equipment and certified across ISO 9001, ISO 14001, ISO 26000, VCA, STEK, OK CV, KNX Partner, BRL6000-21 (ground energy systems), and the mandatory CO-VRIJ/BRL6000-25 gas combustion certification. Notable technical differentiators include all-electric installation design (heat pumps, PV, balanced ventilation with heat recovery, floor heating/cooling), Hydraloop greywater recycling, and energy-neutral design capability — evidenced by the company's own energy-neutral Winterswijk headquarters and KNX-controlled all-electric projects such as the Vink Kunststoffen office and Obelink distribution centre.

Commercially, Wassink generates revenue primarily through project-based installation contracts (new-build and renovation) recognized on handover, augmented by recurring service and maintenance contracts sold and managed by a dedicated service coordinator team, plus a 24/7 emergency call-out hotline (088 – 344 88 99). Pricing is project-specific and not publicly disclosed; the company sells directly without resellers or channel partners. Recent strategic direction includes the explicit decision to discontinue private/residential service (maintenance wind-down by 1 June 2026, breakdowns by 1 September 2026) and concentrate on enterprise B2B accounts, while continuing to invest in energy-transition-aligned installation capabilities. The customer mix is concentrated in regional housing corporations, healthcare organizations, and a small number of repeat main-contractor partners, with ownership entirely held by 4th-generation directors Anne Wassink and Derk Wassink.
