4Kant Bau GmbH

Based on the positive reviews, we chose this local roofing company and were not disappointed. Our roof was re-covered, insulated, fitted with new dormers, flashed, and new casement windows were installed. Overall, a clean and reliable job with a beautiful result. The employees are all friendly, polite, and helpful, and the management is always available. We highly recommend them. P.S. Pictures taken during the re-roofing.

We had our roof renovated and brought up to the latest energy efficiency standards by 4Kant. We have nothing but good things to say; the roof turned out great, and communication with both the employees on-site and the back office was always excellent. Highly recommended!

We had Vierkant carry out a complete energy-efficient roof renovation, including replacing all of our skylights and repainting the facade – all in close coordination with an external energy consultant. Both the roof and facade teams did a fantastic job: reliable, clean, and with high quality standards. What was particularly positive was how quickly and easily they responded to a heavy rain event – ​​even on a Sunday evening, support was immediately available to ensure everything was safe. A very reliable and dedicated company that I would happily recommend.

We had 4Kant renovate the facade (removing old wood, replastering, and painting). We were completely satisfied from the initial consultation to the final execution. Everyone was very friendly and competent at all times. The work was completed quickly and very cleanly.

Highly professional and friendly tradespeople! Their approach was completely fair and transparent. All agreements were honored, and they even adhered to the schedule. No complaints whatsoever – we are extremely satisfied and highly recommend them. Top-notch!
