Competent; trustworthy; and overall fantastic service! I highly recommend Proof GmbH (in particular "Jan" - he really knows his stuff - by far the best around - and a gentleman to boot!)
Great guy
We had the following work done by Proof: Asbestos roof renovation with insulation, and a complex in-roof photovoltaic system with battery storage. For me, Proof GmbH is one of the best construction companies in the region. Excellent communication, incredibly friendly and reliable staff, and a straightforward approach to unforeseen challenges. I can wholeheartedly recommend Proof GmbH!
We thank Proof GmbH for the competent planning and efficient execution of our photovoltaic system. They were reliable and professional throughout the entire process, and always available for consultations. Highly recommended.
Mr. Almer and his team did a perfect job. The installed photovoltaic system with battery storage stores and supplies the solar power as planned. We thank Proof GmbH for their professional advice and work.
Proof GmbH impressed with competent advice, quick offers and efficient and professional implementation. We are happy to recommend Proof GmbH.
