In 1980, 1981 and 1982, there were further repairs to the ceiling of the presbytery and staircase of the choir; substitution of the zinc flap edges and tile flooring. In 1980, the LNEC realized a study of the stone, for signs of degradation based on physical, chemical and petrographic assessments. These investigations were followed, in 1983, by conservation and cleaning of the facade, using hydraulic hoses to remove the dirt, accompanied by hard-bristle brushes and soft sponges. In 1984, the DGEMN, demolished and reconstructed the firewall with plaster and whitewash; chipping away the plaster facade and replacing it with new plaster of mortar, whitewashing the completed surface; repair and replacement of the pavement of the choir; replacement of the ceiling plaster, paint and window grills; varnishing the doors; substitution of glass; cracks and joints were grouted in the facade, with new stone replacing older rock, which was removed and replaced.
