About SPI

SPI was developed by engineers who were finding it increasingly difficult to find companies who offered professional, reliable and thorough specialist surveys in 3 key areas; CCTV Drainage Surveys, Cavity Wall Tie Surveys and Trial Hole Investigations.

Fed up of companies that were only interested in finding repair work or waiting at sites to check surveys were completed properly, SPI was formed to provide a quality specialist property investigation service for building professionals and home owners who want a credible and professional opinion.
