A late Rob Parker try for Castleford denied struggling Crusaders their first Super League win in eight games.
Jordan Thompson had given Tigers an early lead but Jason Chan, Lloyd White and Jordan Tansey all went over to give the hosts a 14-6 lead at the break.
Nick Youngquest then crossed to reduce the deficit to two points before Jarrod Sammut put Crusaders back in charge.
Ben Davies then made it 20-18 before Parker and a last-minute penalty from Kirk Dixon saw Cas win by six points.
POST-MATCH REACTION
Crusaders coach Iestyn Harris:
"It is extremely disappointing because I was expecting us to kick away in that second half. "We just kept giving them opportunities. The players are upset in there and we can't blame anyone else but ourselves.
"In the first half, we looked dominant and comfortable and ready to kick on. We just didn't come out afterwards and, in fairness to Cas, they just dug in
and stuck there. They did all the little things."
Castleford coach Terry Matterson:
"We really played dumb all game. I feel for Crusaders, I really do.
"That's three home games that they probably should really have won. It is a learning experience for them and I feel for them - but not that much, I suppose.
"I ripped into the players at half-time. I thought we were just not there and I was pleased that it was only 14-6 as that score could have been 24-6 - and really should have been.
"We came back and got back into it and then gave an intercept. That side has to improve massively before playing Huddersfield next week."
