Residents from Sydney's cracked Mascot Towers have asked for the NSW government to help fund remediation works because a third of them can't afford to pay a special levy.

Residents of the 132 apartments were evacuated in mid-June due to cracking in the primary support structure and facade masonry.

Owners passed a motion in late August to raise a special levy worth $7 million for stage one rectification works.

But on Monday, the strata committee wrote a four-page letter to NSW Better Regulation Minister Kevin Anderson arguing a survey of owners suggested 35 per cent wouldn't be able to pay their portion of the levy.
