Common questions
What facility leaders ask before making a change.
Need something more specific? We will walk the facility and talk it through directly.
View all frequently asked questions →What types of commercial facilities does Cortex clean?+
Cortex supports multifamily communities, offices, restaurants and hospitality spaces, fitness and recreation venues, schools, churches, warehouses, manufacturing and food production facilities across Chicagoland.
How is a cleaning proposal developed?+
We begin with a walkthrough. The proposal is then built around your facility, operating schedule, priorities and budget rather than copied from a standard package.
How does Cortex maintain quality after launch?+
Each account has three levels of accountability: the on-site team, dedicated supervision and operations or ownership. Inspections, direct communication and recurring reviews keep the program aligned.
What happens when service falls short of the standard?+
The issue is assigned to the account leader, addressed promptly and reviewed with the team. Cortex also looks for the cause so the same problem does not become part of the routine.
Does Cortex provide backup coverage?+
Yes. Cortex arranges trained replacement coverage so the client is not asked to solve staffing gaps or absorb a missed service day.
