DIASA GmbH

Unreliable and disappointing We had scheduled a core drilling appointment with this company. However, they didn't show up on the agreed date, and there was no notification or explanation whatsoever. We tried contacting them by phone several times, but our calls were ignored. When we finally got through to someone, we were met with nothing but excuses – supposedly, the employees suddenly had to work elsewhere. Despite this, we hadn't been informed of this beforehand. After this call, our phone was ignored again, leaving us with a completely unreliable impression. I cannot recommend this com

From order placement to completion, we had only positive experiences. The services offered were performed to our complete satisfaction.

Unfriendly and arrogant. I requested a quote via email on February 17th, 2020, but as of today, February 29th, I haven't received any response. This is no way to treat a potential customer. I cannot recommend this company. Unfortunately, I have to give at least one star to post without one.

We had a major renovation project in our house. After our inquiry, we received a quote quickly. The price was excellent. The work was extremely clean and fast. Everything was covered. Construction debris was disposed of. Professional equipment was brought and set up. The employees were very friendly. We highly recommend this company.

Very fast and efficient work. Excellent value for money. Thank you for the good and fast work!
