Your partner for sustainable building shell renovation

Our services

We offer our customers a complete solution for building shell renovation and maintenance.

We do this in a sustainable way by taking into account environmental aspects, social responsibility and responsible corporate governance.

Our companies are entrepreneurial specialists in roofs, windows, facades, garages, courtyards and solar cell installations. With this specialist expertise as a starting point, we create the conditions for complete solutions through collaboration between the companies.

When you renovate a building’s shell, the property’s energy consumption can often be significantly reduced. This means lowering costs as well as reducing the building’s carbon footprint. It can also create a more appealing appearance by revealing old details that have been obscured by climate impact over the years. In short, we can help our customers to reduce costs, make an effort for the environment and also often contribute to a more attractive urban landscape – an ideal combination!

Our ambition is to become a leading player in the Nordic region by growing organically and through acquisitions. We achieve this by having a strong customer offering and creating an environment that is able to attract and develop the best talents in the industry. We have a passion for ensuring both satisfied employees and customers and we monitor our progress in these areas closely and continuously.

Sustainability

Sustainability permeates everything we do at Corteco – from how we conduct projects to how we develop our employees and manage our companies.

Corteco strives for a transparent business climate with high standards of business ethics and an open dialogue. Employees, customers and suppliers can therefore use our whistleblower function.

We are sustainable and responsible

Our company strives to maintain a transparent business climate and high business ethics. We value the safety and respect of all those affected by our activities.

Our whistleblowing service

Our whistleblowing service exists to capture early warning signals and thereby reduce risks. It is an important tool for promoting high ethical standards and maintaining a high level of trust in us as a company.

The whistleblowing service can be used to alert incidents, events or misconduct that may affect employees, our organization, society or the environment.

Employees and others are encouraged to report suspected cases of misconduct or unethical behavior within Corteco. The report may include information about crimes, irregularities, and violations - or other acts contrary to EU or national laws, in a work-related context.

You do not need to have any evidence to support your suspicions, but all reports must be made in good faith.

Corteco's whistleblowing function allows for completely anonymous reporting of any problems or potential non-compliance via an external party. It is important to include information on where the incident in question occurred and who it affects.

How it works

  • Submitted data will be handled, investigated and followed up properly and discreetly with the possibility of anonymity and confidentiality throughout the process.
  • If you report via our online tool, you can follow your case via the portal.
  • Sharing your personal data is voluntary but remember that this makes you non-anonymous.
  • Any kind of retaliation against a whistleblower is a violation of the Corteco Code of Conduct and will not be tolerated.
