Gassmann Haustechnik AG — Waldbort 1323D, 3823 Wengen BE, Switzerland

We hired Gassmann to remove the old oil furnace in our chalet and put in a new heatpump. Mark Gassmann was very helpful in choosing the right brand and where to put it, and getting the various permissions in place. He also did an great job coordinating the subcontractors. The quality of the work was excellent and was done on time. We are very satisfied.

I highly recommend Gassmann Haustechnik AG for their exceptional service. Marc Gassmann and his team provided timely and high-quality plumbing work during our recent bathroom renovation. Marc's cheerful demeanor and excellent English made the process seamless. They ensured our project stayed on schedule and addressed any follow-up questions promptly. Gassmann Haustechnik's professionalism and dedication to excellence make them the go-to choice for any plumbing needs.

Frederik Franke

Very friendly, attentive service – they're always helpful and strive to get everything done as quickly (and well) as possible. They also have ideas for older houses, where you sometimes have to be flexible to repair something.

We've been customers for many years because the service is top-notch in every respect, customer-oriented, and always very friendly. This was true before the change in management and remains so under the new leadership. Highly recommended. Monika & Bruno Wägli
