If facades need to be cleaned, we can provide experts familiar with the appropriate types of cleaning work. One of our particular areas of expertise is drafting specifications that reflect the state of the art and contain concrete requirements and agreements, as is also taking detailed site measurements of the facade area. Any shadow gaps, glass surfaces and areas covered by venetian blinds that require cleaning are recorded separately. The Institute can also lend a hand when it comes to awarding contracts for and monitoring any cleaning work. Acting on behalf of the Gütegemeinschaft Reinigung von Fassaden e.V. (GRM, the Quality Association for Facade Cleaning, see www.grm-online.de), we independently monitor the work carried out by facade cleaning companies that hold the GRM quality mark.
