Office and industrial cleaning companies, window cleaners, façade cleaners, facility service providers, landscape gardeners and grounds maintenance and pest control: for suppliers of cleaning products, machines, workwear and software who want to reach these firms by province.
Our Belgian database holds 779,149 records (as of 5 November 2026); they are not yet assigned to industries. The quote states the size available for this industry.
Export of the whole industry: €379 (excluding VAT). Selections by province, municipality or your own filters are quoted on request.
Official statistics: 28,628 businesses in Belgium according to Eurostat, Structural Business Statistics (sbs_ovw_act), number of enterprises (reference year 2024, Eurostat update of 30 September 2026, retrieved on 4 November 2026). Division 81 services to buildings and landscape activities: combined facilities support (81.1), cleaning (81.2) and landscaping (81.3). This is the size of the market, not the size of our database.
The industry corresponds to NACE-BEL division 81: services to buildings and landscape activities. It covers general and specialised cleaning, facility services and the creation and maintenance of gardens and green spaces.
Two groups need attention. Household help paid with service vouchers (dienstencheques/titres-services) is a separate market; tell us in your request whether to include or exclude those firms. Construction firms laying patios or driveways are under Construction and installation.

There is no professional register for cleaning and landscaping that works as an address file.
These 14 columns are included.
Apart from a few large cleaning groups, the industry consists mostly of small firms and self-employed people. Suppliers of machines or products often make the website a required field: this brings the firms with an established structure to the top.
For a telephone campaign to gardeners and cleaning firms, you must first check the numbers against the Do Not Call Me list; this also applies to B2B campaigns. Many small firms only list a mobile number, which may be on the list.
Landscape gardeners work seasonally. A mailing in late spring is received differently from one in mid-summer, when the crews are working outdoors.
We distribute professional cleaning machines and are looking for cleaning companies and window cleaners (81.21 and 81.22) in the provinces of Antwerp, East Flanders and Flemish Brabant with a website, for an invitation to a demo day. Please exclude service-voucher companies.

Questions
Yes, on request, based on the category and the name in the source (in the statistics, class 81.30). Our records do not yet carry a NACE-BEL code; before quoting we tell you how reliable this selection is. Many gardeners are self-employed; for them a letter, or a telephone campaign after checking the Do Not Call Me list, are the suitable channels.
That depends on their activity code and on what the source shows. Tell us in your request whether to include or exclude them; before quoting we will tell you how well we can identify them.
