Salvin replaced the bell-storey by a roof similar to the original roof. This was made necessary because the weight of the bell-storey was too much for the walls to support. The 15th-century Gothic windows were replaced by windows in Norman style, and a formerly-inserted gallery was removed, together with the external staircase leading to it. To compensate for this, a new south aisle was added. It was found that the east wall of the chancel was unstable and this was replaced. Then the north aisle, by that time in poor condition, was also rebuilt, extending it to the same length as the chancel. The floor, previously black marble, was relaid in tile. The original estimate for the cost of the restoration was £1,000 (), with the parish paying £300 (); in the event it cost nearly £4,000 ), with the parish providing only £50 ().
