Die Olligs GmbH

We came across Die Olligs online for our bathroom renovation. After the initial contact and consultation, it was clear to us that we would commission this company. The decisive factors were the very professional impression and, of course, the competent consultation with Mr. Werlich Sr. This impression was confirmed when construction began. The tradesmen from the various trades, as well as Mr. Werlich Jr., worked cleanly, neatly, and reliably on site. Furthermore, either Mr. Werlich Sr. or Mr. Werlich Jr. were always available to answer questions during the construction process. We are very sat

Our house, built in the mid-1950s, was previously heated with gas. Mr. Werlich had already sparked our interest in an air-to-water heat pump combined with a photovoltaic system some time ago. Now, the Olligs have found an excellent and unique solution for our limited living space: installing an indoor heat pump system and connecting it to the existing heating network. The Olligs impressed us in every phase of the project – from planning and grant application to the final invoice. The installation went perfectly: all trades worked on schedule, with great care, and the work site was always clean

Excellent work in record time! It's a real pleasure working with this company: highly reliable, highly competent, and hardworking. We had our bathroom renovated by Olligs. Thanks to their excellent advice, the result is outstanding. We are thrilled – our recommendation is a 5-star "plus"!
