Satisfied customers are the most important thing for all employees at KRONE, and we work hard to produce and deliver flawless products. Unfortunately, errors can still occur in production or during delivery to the recipient, resulting in a complaint.

For submitting a complaint, please fill out the complaint form below. The inquiry must always include the order number and position number of the relevant KRONE elements. Click here to see how to find the window's variant label with information.

Please remember that damaged elements should never be installed before the complaint is submitted and KRONE has given approval for installation. Note! If you are a private homeowner, please contact the carpenter or timber trade where you purchased your windows, and they will then contact us to plan the next steps. We strive to handle all inquiries as quickly as possible, and we look forward to assisting you.
