In 1970, the skylight was repaired; improvements made to the electrical system were made in order to install a projector; reconstruction of the wood structures and stuccoing of the ceilings; construction of hydraulic rigging and screed in the pavement; painting of the walls with water-based paints. There was a proposal by the LNEC and IJF to study the area in order to treat the deteriorating stoneworks at the end of the 1970s. But, in 1978, the facade panel was partially destroyed through the restoration attempts of the IJF. By the end of 1979, there was a further reassessment of the roofing in the registry, altar and lateral chapels for repairs; demolition and reconstruction of the framework and pavement of the lateral chapels; substitution and assessment of the zinc eavestroughs and flaps; and repair and cleaning of the roof.
