De Blasio plan failed to improve school custodial service: study

Mayor de Blasio promised to clean up school custodial services last year — but the mess is as bad as ever, according to a new report.

De Blasio handed control of custodial services to a not-for-profit organization, promising big savings and improved transparency.

But a Families for Excellent Schools study concluded that the setup is marred by the same problems as before — high costs, murky visibility and erratic management.

The charter-school backers said transitioning to New York City School Support Services has cost at least $105 million — more than 2.5 times de Blasio’s original $40 million price tag.

Custodial salaries were already ballooning before the move, with the average worker making $140,000 a year — up 28 percent from Mayor Michael Bloom­berg’s last year, according to FES.

Hizzoner also promised a decrease in supplies and contractual services costs with the new format.

But FES found that spending in those two areas was already $31.7 million over this year’s modified budget allocation.

The DOE blasted the report as inaccurate.

“This is completely misleading and has too many inaccuracies to qualify as a report,” said spokeswoman Toya Holness.
