Dirkzwager Groep

What Dirkzwager Groep does

Dirkzwager Groep B.V. is a Dutch multi-disciplinary property maintenance firm founded in 1937 as a painting company in Amsterdam and now headquartered in Almere following a 2001 relocation. The company operates across five integrated disciplines — betonrenovatie (concrete renovation), bouwkundig onderhoud (structural maintenance), mutatieonderhoud (turnover maintenance), planmatig onderhoud (planned maintenance), and service & dagelijks onderhoud (24/7 daily maintenance) — with painting (schilderswerk) as its oldest heritage discipline. It is a family-owned private limited company (B.V.) under the Uitermark family (Kevin Uitermark as Managing Director since 2016, Daan Verleng as Financial Director), with two wholly owned subsidiaries (Dicon-Lo-Pres for epoxy injection and Dirkzwager Bouw B.V. for building maintenance) and approximately 90 employees.

The business is delivered through direct B2B field sales to housing corporations (woningcorporaties), VvE administrators (HOAs), municipalities, and private property owners, primarily across the Amsterdam metropolitan area, Almere, Gooi, Utrecht and Flevoland regions. Revenue is generated through project-based contracts, including long-term Resultaatgericht Samenwerken (RGS) agreements and multi-year maintenance plans, with add-on EPA energy performance advisory and an emerging circular renovation service line. Operations are supported by PCA–Marlin Service planning software (AI-based route optimization and pattern recognition), tablet-based digital field forms, and SMS-based resident communications; proprietary capabilities include the Lo-Press two-component epoxy injection technique developed via subsidiary Dicon-Lo-Pres.

The company differentiates through a dense certification stack (ISO 9001, VCA, BRL 3201, VGO Keur, OnderhoudNL Erkend, Erkend Leerbedrijf), 86+ years of brand heritage, RGS-certified execution capability, and an institutionalized sustainability/circular economy program (partnerships with Re-Use B.V., Stiho/Urban Mining Collective, Trees for All, plus stated targets of 50% CO2 reduction by 2030, 80% electric fleet by 2025, and 20% circular timber on 2025 projects). Go-to-market is supported by company website content marketing, organic LinkedIn/Facebook (since 2019), employer branding through the 'Even voorstellen' series, and school/vocational training partnerships.
