Recommendation
At the crack of dawn, three Harsch men stood in front of the door and set to work in a focused and structured manner. A lamp outlet, three cans of uP and a can on the other wall opposite had to be installed. Others stand in the dust and can't see anything, unlike the Harsch men. They work very dust-free and have a clear view. After just under two hours, everything was done, tidied up and the Harsch men left the site. The appearance and the execution of the work only lead to the conclusion, gladly again and again. Highly recommended

Recommendation
I would absolutely recommend TK E (I already have and this one is also now a customer of theirs). Super quality, very reputable and good craftsmen. I also believe that if I ever need the service, it will be there. I will always work with local craftsmen. TKE probably work with the products they have the least trouble with. Alternative storage systems other than SENEC, for example, are not offered. From quote to installation was a bit opaque. Ordered on 02/23. Call on 01/24 regarding status. 3 weeks later the system was installed. I never received an answering machine or anything similar. I would have liked someone to have come to check it out.

All in all, I am convinced that TKE is a very good company and I would hire them again if I could afford TKE.

Best regards

I can't imagine that things could be better than with etec. From the first conversation and offer after a short time, from the deadline or deadline prediction, from calls to improve the offer, from the competent and friendly professional roofers and electricians and scaffolders (never seen scaffolding on other houses for the installation of non PV systems), who answered or explained every question, from the cleanliness of the work and the latest materials used. All more than super and full satisfaction. Will recommend etec at every opportunity.

We have been a customer (MFH) of Janssen since 1998. Since then, we have had a wide variety of work carried out (various heating boilers replaced, various repairs in the sanitary and bathroom areas). Mr. Janssen and his team have provided us with competent, expert and friendly support on every project. Deadlines are met. When unexpected problems have arisen, we have always been helped quickly and promptly.
