MCS Solutions notes that in-house cleaning services clean more slowly than their contract counterparts in as many as 70% of the cases on the cleaning market. Obviously, this number does not include any special services that are more frequently provided in-house, such as serving coffee, washing dishes, etc. Another basic fact is that the cleaning agents, supplies and techniques used are well integrated in both alternatives and can be regarded as equivalent.

It may be said that the lower in-house cleaning productivity is compensated by its usually lower (overall) cost per hour. However, despite this, there are sometimes still big differences. In the case of mixed cleaning organisations – i.e. where in-house staff and contract cleaning are combined – it remains difficult to explain and justify these differences to management.

Can this difference in cleaning speed be tolerated? How should you deal with it as an organisation?
