About us
Firma Griephan is an SHK (plumbing, heating and air conditioning) trade business founded in 1975, based in Dassow on the Baltic Sea. The owner-managed master craft business covers the complete spectrum of sanitary, heating, air conditioning and ventilation technology: sanitary installation, bathroom construction and bathroom renovation including barrier-free bathrooms and wellness bathrooms, heating system construction and heating modernisation, heat pumps, solar thermal, rainwater utilisation as well as air conditioning and ventilation systems with maintenance. For commercial and public customers, the company implements sanitary facilities, ventilation systems, refrigeration and electrical technology, plumbing and metal roofing work, pipe cleaning and leak detection as well as security and alarm systems. In addition, the company offers services for planners and architects, bathroom planning and an online shop for SHK products. In 1995, Michael Kreft, master installer for gas & water, took over the business that had been left without a leader after the sudden death of its founder, and has since run it with a focus on ecological construction and modern building technology.
