Our expert network
Strong partners. Short lines. Reliable solutions.
Trusted specialist partners protect asset value and provide rapid support for every property. Professional property management goes beyond commercial organisation, owners’ meetings and accounting. Property values are created through sound decisions, expert partners, short response times and a dependable network of experienced specialists.
At Wellhöner Immobilien, we therefore work with selected specialist companies, surveyors, energy consultants, notaries, lawyers, insurers and service providers. Together, we create the basis for sustainable management, reliable maintenance and the long-term development of residential and commercial property values in the Ruhr area.
Our network combines regional expertise, direct coordination and many years of experience. Owners’ associations, landlords, investors and property owners all benefit. Whether technical support, refurbishment, energy consulting, legal protection or claims management is required, we coordinate the right specialists and ensure transparent, commercially sound processes at your property.
Property management means responsibility. Damage must be coordinated, refurbishments prepared, legal questions resolved, technical systems maintained and owners kept fully informed. A capable network offers decisive advantages:

FAQ: Our expert network
As an owner, do I get access to the partner companies used by my property management?
No. The partner companies work on behalf of and under the coordination of Wellhöner Immobilien. Through the owner portal, however, you receive full transparency on commissioned services, quotations and invoices. Where appropriate, we arrange direct contact—for example for energy consulting or financing.
Does Wellhöner earn commission by recommending partner companies?
Our focus is independent management in the interests of the owners’ association. Appointments are made transparently, are fully traceable and follow the relevant resolutions. Any commissions are disclosed where they concern the owners’ association.
Can I propose my own contractor for refurbishment work?
Yes. We review every proposal in terms of qualifications, insurance and value for money. If the requirements of the owners’ association are met, we are happy to involve regional firms—strengthening the local network.
Why does Wellhöner publish its partner companies?
Because trust depends on transparency. A visible partner structure shows owners and advisory boards who stands behind the services. You can understand how we organise damage, refurbishment and expert assessments even before you first contact us.
The network complements our own quality standards—from professional property-management certification under section 26a of the German Condominium Act to transparent digital processes.
Would you like us to review your network?
We will gladly show you who we work with at your property—personally and transparently.
