Private Investigations

Sentry Investigations Ltd offer a wide range of private investigation services for an endless list of reasons, but they generally involve family or relationship problems. Clients often wish to find out if their partners are having extramarital affairs, so they contact us to gather the evidence they so desperately need to put their minds at rest. Cases like these on occasion actually prove a partner's innocence. However, cases like these are few and far between.
