In 2001, Mensing joined Clyde on loan from Wimbledon. He quickly became a regular in his right back role, and won the Young Player of the Year award in his first season. He joined Clyde permanently in May 2002. Mensing became a huge fans favourite, with his aggressive style of play and was given the nickname "Gunter" due to his German roots. His versatility was also an important feature of his game, playing in every defensive role, as well as midfield on several occasions, and occasionally as a striker.
Mensing scored the only goal of the game in St. Johnstone's win at Queen of the South in the second league game of the 2006–07 season. On 28 February 2007, Mensing was named as the BBC's Man of the Match in St. Johnstone's televised 2–1 Scottish Cup win at Motherwell, a result which took the Perth club into their second cup semi-final of the season.
Mensing moved from Motherwell to local rivals Hamilton Academical on a three-month loan deal in September 2007, after finding it difficult to progress beyond being a squad player. After extending the deal for an additional month Hamilton then signed Mensing permanently on 18 January 2008. He won promotion to the Scottish Premier League with the Accies in 2007–08 as Division One champions. Mensing was banned for a month in 2011 for testing for a banned substance methylhexaneamine. The positive urine test was taken after the game against Aberdeen on 29 December. He missed five games for Hamilton in total. Mensing revealed that the substance was in a dietary supplement he had been taking purchased of the high street and he had taken advise before taking and believed there to be no banned substances in it. Hamilton and Mensing only revealed details of the ban after it had been served. He was banned between 29 January and 28 February 2011. Despite the ban, Mensing maintain his innocent for testing for a banned substance methylhexaneamine. Mensing left Hamilton after season 2011–12 after spending five years at the club.
After being released by Hamilton Academical, Mensing went on trial with Morton for most of the summer 2012 pre-season, and played as a trialist in a 1–1 draw with his former club Hamilton. On 14 September 2012, Mensing signed for Raith Rovers on a one-year contract despite Hamilton offering him a new contract. On his debut against Airdrie United, he got the man of the match award and his performance was praised by manager Grant Murray. Mensing scored his first goal for Raith Rovers in a 4–4 draw with fife neighbours Cowdenbeath.
On 22 May 2013, Mensing signed for Livingston on a two-year contract. He was named captain of his new club on 10 July 2013, and scored a penalty on his competitive debut on 3 August 2013 in a Scottish Challenge Cup match against Berwick Rangers.
