The aim and task of heritage conservation is to preserve historical monuments or the existing building fabric in the long term. The motto is to adapt the existing building stock to new conditions and regulations by means of suitable measures and minor optimisations. So that the culture is also secured and preserved for future generations. With the patented Heritage process from Jos Berchtold AG, it is possible to preserve door elements with minimal intervention while retaining the original surfaces (on both sides).
Careful restoration, preserving beauty.
Finished with respect for the original.
