Redruth stay sixth in National Two South after claiming their first away win in two months with a 33-10 victory at bottom side Westcombe Park.
Aaron Penberthy kicked three penalties and converted Tom Cooper's try as the Reds led 16-0 at half time.
Bradley Kayton got a try back for the hosts before Tom Notman crossed a minute later.
Chris O'Neill got another back for Park, but late tries from Craig Bonds and Greg Goodfellow sealed victory.
"We said in the week that it was a very good opportunity as they're the basement club at the moment," Director of Rugby Dave Penberthy told BBC Radio Cornwall.
"Their home form hasn't been too bad and they've held clubs quite close, so to come away with over 30 points on the board and five points is very pleasing."
