Daniel Nkrumah struck twice after the break to earn the Beavers a victory and deny Dom Di Paola’s side the chance to build on their midweek win over Bath City.
A largely uneventful first half gave way to home dominance, with Horsham unable to force a comeback.
Horsham are 15th in the table and are on the road again next weekend, to Torquay.
