Most common site defects of 2022 revealed

Published date: 18 January 2023

A quarter of all defects found on projects inspected during construction by Premier Guarantee in 2022 related to issues with external walls.

Though it is relatively common for issues to appear during all construction developments, our figures show that there are typical areas of concern that feature regularly.

Thankfully, these defects are spotted by our team during the construction process ensuring that the very highest standards are ultimately met. It is never a bad time, however, to be made aware of recurring hurdles so that you can avoid them in the future.

Issues around external walls saw a 9.5% rise from the previous year and amounted to 24.97% of all defects found from January to December of last year.
