Super advice, very competent. So far I have used it once for a liability damage, it was about a locking system in a multi-family house and everything worked smoothly and perfectly. Absolutely recommendable!

Fast, friendly, uncomplicated, and reliable! I have already used the service 2 times. Short-term appointment scheduling, punctual on-site, and quick in the way of working. The staff are very friendly and accommodating! Absolutely recommendable!

I made an appointment with the company at the beginning of December 2020 to inspect our front door for the installation of a security bolt on our front door. I received an appointment for January 5, 2021. After the on-site inspection, I was told that I would receive a cost estimate in the next few days. At the end of January, I called the company and inquired; I was informed that the cost estimate had not yet been processed. I then called the company Sicherheitstechnik Schulz from Siegen Kaan-Marienborn. On the same day, the boss of the company was there, took measurements, received the cost estimate by email in the evening, and a week later the security bolt was installed on my door. Now that's what I call service. By the way, I am still waiting for the cost estimate from the company Haus für Sicherheit.

Friendly in tone, but unfortunately, despite the order, no lock installation was completed on our front door. We unsuccessfully tried for several months to get someone from "Haus für Sicherheit" to secure our front door - and by no means as a "free service"; we would actually have gone so far as to want to pay the craftsman (irony off). After an initial conversation on-site, no one from "Haus für Sicherheit" ever appeared again. Apparently golden times for companies offering burglary protection... Addendum: We then went to the company "Bossmann" in Siegen. Flawless work, fast, very competent, and with the necessary "sensitivity" for a front door over 100 years old. Recommendable!
