A few weeks ago, the Sonnengrubers replaced our aging gas heating system with a modern heat pump – and we are very happy with the result! The consultation was thorough, competent, patient, and tailored to our individual needs. They explained everything clearly, weighed the options, and addressed our actual requirements.

We are absolutely thrilled with Florian and Thomas Sonnengruber! They not only kept our scheduled appointment for a quote, but went far beyond that.

After a lengthy search by our previous heating company, they finally shed light on the issue. Highly professional, extremely conscientious, and with excellent communication – we wholeheartedly recommend them!

Our bathroom project was perfectly executed by Sonnengruber. Everyone was incredibly punctual and professional. They fulfilled our wishes in record time. The quote and invoice were spot on. Thank you for the fantastic work.

Highly competent and reliable, with absolutely seamless communication. We had our bathroom completely renovated and we are totally satisfied, as everything went exactly as agreed. The tradespeople were always punctual and worked very cleanly. The costs were the same as quoted (absolutely fair prices), so there were no unpleasant surprises afterward. Sonnengruber also had a perfect tiler available, and both companies worked together seamlessly. We can absolutely recommend Sonnengruber.
