Bravo Bravo eine sehr gute Firma

Von der Beratung über die konkreten und transparenten Offerten über die äusserst fachgerechte, genaue und kompetente Herstellung mit den termintreuen und präzisen Montagen sowie den korrekten Rechnungen konnte ich diese professionelle Firma kennenlernen. In der ganzen Zeit wurde ich über den Stand der Dinge informiert. Super! Danke. Herr Mühlemann geniest mein volles Vertrauen und ich werde bei einem nächsten Bedarf sicherlich auf ihn zurückkommen.

ph plus GmbH is a young company founded in the spring of 2015 originally as a sole proprietorship and converted to a GmbH in 2017 by Filipe M. Pratas and Janine Gauch. From the very beginning, ph plus was able to attract a small, yet highly experienced and well-coordinated team of facade and construction specialists, and has expanded this team over the subsequent years. Our primary goal is to enhance the quality of your facade through sustainable monitoring and maintenance, thereby extending the lifespan of your building envelope and ensuring its functionality. We place great importance on regularly training our employees to keep them up-to-date with the latest technology. Thanks to our many years of professional experience, we are also very familiar with older facade systems. ph plus has an office, a workshop, and a storage facility in Basel with a total area of nearly 700 m2. Additionally, we own service vehicles that are excellently equipped and continuously maintained. We offer our services throughout Switzerland.
