1. Which tenders concern a window cleaner?
Direct answer: window cleaning appears either as a standalone service or as a lot within a wider cleaning contract, on commercial and public buildings.
Window cleaning and glazing firms bid for structured public and private clients: local authorities, schools, hospitals and clinics, landlords, commercial property funds, office-building managers, shopping centres. Glazed-surface cleaning is almost always periodic, which makes it a recurring contract.
- Standalone window cleaning service: a dedicated contract for periodic cleaning of a site's glazed surfaces (office building, school, station).
- "Glazing" lot of a cleaning contract: window cleaning is isolated as a separate lot within a wider premises-cleaning contract.
- Call-off framework: glazing interventions triggered by successive orders across a building portfolio, over 1 to 4 years.
- Multi-site contract: window cleaning of a dispersed estate (social landlord, branch network, hospital campus), with frequencies differentiated by site.
Across the EU the logic is identical in all 27 member states: a public operator publishes above the European thresholds on TED, below them on its national platform. A central purchasing body can also offer cleaning contracts including glazing. An established firm may bid for a cross-border contract subject to freedom of establishment and recognition of qualifications.
Key takeaway
In window cleaning, the passage frequency drives the annual volume, not the surface alone: the same glazed façade cleaned twice a year does not cost the same as the same façade cleaned twelve times. The price schedule must therefore cross surface, frequency and access means, item by item.
