In Manhattan the hard part is rarely the cleaning. It is the freight elevator, the loading dock window, the certificate the managing agent needs before your crew reaches the floor. We plan the building first.
A cleaning contract in a Manhattan high-rise lives or dies on logistics. Most buildings release the freight elevator for vendor use in a fixed window, often between 6pm and midnight, and that window is shared with movers, contractors and deliveries. A crew that shows up without a reservation loses the night.
Before a single floor gets touched, the managing agent usually wants a certificate of insurance naming the ownership entity, the managing agent and sometimes the building LLC as additional insured, with exact wording. Getting that wrong costs a week. We treat the COI as part of mobilization, not paperwork to chase afterward.
We also confirm the practical questions early: which entrance the crew uses after hours, who signs them in, whether the building engineer needs notice for after-hours HVAC, and how waste leaves the floor — chute, compactor or carry-down to a carting staging area.
Class A and B office floors have a predictable rhythm. Glass conference rooms and interior partitions show fingerprints under downlighting, so glass is a nightly item, not a periodic one. Pantries carry the heaviest soil load in a modern office because tenants eat at their desks and rinse in the pantry sink.
Restrooms are the item a tenant complains about first and the item a prospective tenant notices on a tour. We run them on a fixed sequence with consumables checked every visit, because running out of paper is a service failure that no amount of floor shine offsets.
Send the building address and floor count and we will come back with questions a serious bidder asks.
