A consultation that makes all the difference
Ein Beratungsgespräch, das den Unterschied macht
During a free initial telephone consultation, we’ll make time to speak with you about your individual needs. You don’t need to be an expert. Together, we’ll calmly review your situation and determine whether any action is required and if so, what this may be. We’ll explain everything clearly and answer any questions so that you feel confident and know the best way to proceed. Of course, there’s no obligation with this initial consultation.
Where appropriate, we’ll recommend a detailed on-site analysis. One of our specialists will visit the property in question and assess the condition of the relevant pipes. This will provide an accurate and reliable overview of your situation. This paid assessment will form the basis for all further decisions. At the same time, we’ll carefully check whether a renovation is actually necessary, ensuring you avoid any unnecessary work or costs.

Total pipe interior renovation completed to the highest standard. The timing in January was perfect, as the impressive oil-saving effect was immediately apparent. I would highly recommend the Naef GROUP and its competent team.

The pipe renovation in our entire building was carried out cleanly, efficiently and neatly. We are very satisfied with the information provided and the work performed.

Martin C. Huber
After hearing the positive experiences of two colleagues, we had our 39-year-old underfloor heating renovated by the Naef GROUP – and we were not disappointed. All employees of the Naef GROUP were very professional, competent and friendly, from the preliminary assessment to the follow-up work stage. The job was completed very neatly and precisely, and finished exactly on schedule.
