Is the on-site survey free of charge?

The on-site survey is a professional service and costs 150 euros plus travel expenses. During the survey, an HTS specialist precisely measures all relevant dimensions -- floor-to-floor height, deck opening, wall condition, and installation situation. These exact measurements form the basis for the binding quote and precision manufacturing.

Available free beforehand: You can obtain a preliminary phone quote at any time, free of charge. All you need are 3--4 key measurements that you can take yourself -- such as floor-to-floor height and the size of the deck opening. This gives you an initial price estimate before committing to the binding on-site survey.
