Most clients start with a nightly janitorial contract and add the periodic work to it: floor care on a quarterly cycle, carpet extraction once or twice a year, window cleaning monthly, and a detail clean before inspections.
Bundling matters practically rather than just commercially. One scope means nothing falls between two contractors, one supervisor knows the whole building, and you are not chasing three companies when something is missed. If you manage several properties, we run one consolidated agreement across all of them rather than a separate contract per address.
