Production cleaning has a purpose
Traditional maid service is optimized for speed and cost across many similar homes. One product set, one checklist, one route. For a standard residence that model works well.
It fails in a home where a single wrong product on honed marble, unlacquered brass, or antique flooring creates damage that costs more than years of service.
What changes at the luxury level
Property-specific protocols replace universal method. Team leads verify work against a written scope. Access, discretion, and confidentiality become part of the service rather than an afterthought. And the company tells you what it will not do, in writing, before it begins.
