Maintenance that suits you - individual, flexible and thoughtful
Every property portfolio is different - and so should the maintenance. We offer you tailor-made concepts that adapt to your everyday life: from fixed maintenance contracts to flexible maintenance flex subscriptions.
With a maintenance contract, you are on the safe side: all intervals are clearly defined, appointments are automatically scheduled - you don't have to worry about a thing. Or would you prefer more freedom? Then our maintenance flex subscription is just right for you. Based on our experience and the last cleaning, we know when it might be time again. We'll let you know in good time - you then simply decide: yes or no.
Our strengths:
- Maintenance concepts for large property portfolios
- Plannable intervals or flexible support - according to your needs
- Coordination with your janitors and service providers
- Early detection of problems before they become damage
Your benefit: Carefree, well-maintained properties, greater security - and a partner who takes responsibility.

Your solution for:
- Protection against moisture, blockages and backflow damage
- Early detection and removal of deposits
- Reduction of cost-intensive consequential damage
- Fewer emergency call-outs - thanks to regular, preventive maintenance
Your benefit: preventive protection instead of costly repairs.
