The Government Property and Building Surveyor's Office (Staatliches Vermögens- und Hochbauamt) in Schwäbisch Gmünd had conducted restoration work in the church prior to the anniversary. In preparation the aging pews had been removed. The focus was on measures against the moisture that seeped into everything. Despite extensive research, it was not possible to clearly ascertain its causes. As the church has probably had these problems since its construction, a reconstruction concept was agreed upon in which an attempt was to be made to at least minimize the dampness in individual small steps.
Here the consistent sealing off of the church to the outside, i.e. primarily with new window glazing and draining off of the condensed water collecting on the surface of the glass to the outside. The windows were provided with motor-operated ventilation wings. These motors are controlled with sensors that only open the windows when the outside air is drier than the inside air.
In addition to these measures, plaster surfaces were reworked or reapplied, mural paintings were cleaned and strengthened, a new entrance to the church was set up and the entrance used at that time was covered with a glass roof.
The grave slabs of the noble family von Woellwarth from the 16th century had suffered greatly under the unfavorable climatic conditions. They were carefully removed and lay in demineralized water for approximately three months to neutralize the salts contained in the stone. Then they were carefully restored and reinstalled on separating layers without contact to the floor or wall.
