Our approach
Our professional cleaning step by step
On-site property inspection
We assess your property on site and discuss your wishes in detail. For commercial clients, quote preparation after the inspection is free of charge. For private clients, an offer fee applies for the on-site visit.
Quote for your building cleaning
Based on the joint inspection, you receive a transparent concept. This written quote covers all the necessary cleaning work precisely.
Professional execution of the cleaning
Our qualified team carries out all work conscientiously. This applies to ongoing maintenance cleaning just as much as to an intensive deep clean.
