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.

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.
