Hallmark Clean for cleaning and window cleaning companies

Do you want to show that your cleaning or window cleaning company works professionally and reliably? With the Hallmark Clean, formerly the OSB hallmark, you make that visible. The hallmark was developed by Schoonmakend Nederland and stands for quality, good employment practices and financial reliability.

Normec is 'preferred supplier' of Schoonmakend Nederland. This means that in addition to the audit on NEN 4400-1 we also check the additional, cleaning specific requirements. This way you arrange everything in one clear process.

What does the Keurmerk Schoon mean?

The Keurmerk Schoon was established by Schoonmakend Nederland, the trade organization for professional cleaning companies and window cleaning companies.

With certification you demonstrate that you:

  • Doing business in a reliable way
  • Have insight into your own administration and work processes
  • Works according to laws, regulations and industry agreements

For clients the quality mark is a clear confirmation that they are working with a professional and honest party.

What requirements must you meet?

For the Mark of Quality Clean your organization must meet:

Companies with a turnover of up to 10 million euros can opt for the Schoonmakend Nederland standard, based on NEN 4400-1 and the applicable Handboek Normen SNA. In that case, the inspection takes place once every twelve months.

With the Keurmerk Schoon:

  • Distinguish yourself on quality and good employment practices.
  • Give your clients certainty about limiting chain liability.
  • Receive the support of a strong trade organization.
  • Increase your insight into your own administration and work processes.

Working method

How does the inspection work?

  1. 1.

    Inspection

    In advance you will receive an overview of the documents you can prepare for the inspection. This usually gives a good idea of the parts we are testing. On the inspection day, we review these documents and draw some samples.

  2. 2.

    Report

    Based on the inspections, you will receive reports in which the various components for your company are assessed. Are the standard(s) not met or are improvements needed? Then we communicate this.

  3. 3.

    Frequency

    Once or twice a year we check your organization to make sure that you are still complying with the rules for the Keurmerk Schoon.

    Companies with a turnover of up to 10 million euros can opt for the Schoonmakend Nederland standard, based on NEN 4400-1 and the applicable SNA Standards Manual. In that case, the inspection takes place once every twelve months.
