BiennaDach GmbH — Mattenstrasse 135, 2503 Biel, Switzerland

Don't be fooled by the website!! Beware of this company. They don't adhere to basic quality standards (see photos). Unqualified workers. They don't meet a single deadline. They only give you cheap excuses. Contracts are not honored, and building owners and clients are taken advantage of! CLEAR WARNING AGAINST THIS COMPANY!! A 1-star rating is still too high! The company is now in liquidation!!!!!???

I can only confirm the negative experiences of previous reviews regarding BiennaDach. We also signed a contract for work and services, which is simply being ignored. Our inquiries, both written and by phone, have gone unanswered, despite dozens of attempts by our site manager. This is not only a complete waste of time, but a business practice that can only be described as scandalous. I had a brief opportunity to speak with the managing director, but he proved incapable of making decisions or providing a clear plan for the continuation of the work. Meanwhile, rain is leaking through the incomplete building envelope, posing a risk of further water damage. The fact that the company is taking no action or even communicating about this is beyond negligent. It seems that the company's quality and reliability have declined dramatically since the previous business partner left. The new management is clearly overwhelmed and unable to fulfill the services offered. We are now forced to hire a competitor to complete the remaining work. I strongly advise against working with BiennaDach. Our experience confirms the 1-star ratings, and even that seems too generous.

No response for weeks, registered mail was returned, no reply to emails or phone calls. Do you still intend to finish your work in the lakeside district, or do you consider it complete? Unprofessional!

Paid work not completed. I haven't been able to reach anyone for months. I received the money, but no one has responded.

I am very satisfied with the work and quality
