In 1819 lath and plaster vaulting was installed in the nave, but a year later the vaulting of the south transept was found to be unsafe and had to be dismantled. In the late 19th and early 20th centuries extensive repairs were carried out, which included the insertion of tie-rods in the tower and the underpinning of the nave and south choir aisle walls in 1906. In 1912 a new floor was laid in the nave consisting of 6" of concrete, an inch of fine cement and wooden blocks on top.
