Grimsby's run of four successive league victories was ended as a determined Dagenham side held on for a draw.
A dire first half saw neither side create any chances with two Ben Strevens off-target headers the best the home side could manage.
The action did improve after the break with Jamie Taylor lobbing his shot just over the bar, before hitting the woodwork with a header.
Sam Sloma also struck the post late on and Glen Southam fizzed an effort over.
