This chapel was in a very poor state and was in danger of collapsing, due to engineering works carried out closeby. Extensive restoration works were carried out by the Mosta Local Council. The works, carried out under the supervision of Architect Mr. Norbert Gatt, took two years to complete and were finished in September 2002. Several Government departments were involved, their work being coordinated by The Mosta Local Council. It was reinaugurated on Thursday 19 September 2002 by the Hon. Minister Dr. Francis Zammit Dimech and Mosta Mayor Mr. Joe De Martino, and blessed by the Mosta Archpriest Rev. Fr. Joe Carabott.

The date 1657 is engraved on the chapel door and shows the date when the present chapel was built instead of a previous one. In old days the feast of St. Andrew used to be celebrated here on the 30th November every year.
