Frequently Asked Questions

What types of facilities does Core Building Maintenance service?

We specialize in professional and commercial environments such as office buildings, medical facilities, industrial spaces, and managed properties. Our cleaning programs are designed around how each facility actually operates. This ensures consistent results without disrupting tenants, staff, or daily workflows.

How is CBM different from a traditional janitorial company?

We operate with defined scopes, documented procedures, and on-site accountability — not vague promises. Each account follows a structured checklist and quality control process overseen by a dedicated supervisor. This creates predictable results and fewer management headaches for our clients.

Do you offer customized cleaning plans?

Yes. Every facility has different traffic patterns, surfaces, and compliance requirements. We build a cleaning plan based on your building type, usage, and priorities rather than forcing a one-size-fits-all schedule.

How do you ensure consistent quality over time?

Quality is maintained through routine inspections, performance tracking, and clear communication with our clients. Our teams follow standardized procedures while supervisors verify work and address issues before they become problems. This system keeps service levels consistent month after month.

Are your cleaners trained, insured, and background-checked?

Absolutely. All CBM team members are professionally trained, background-checked, and fully insured. We invest in proper onboarding and ongoing training to ensure safety, professionalism, and reliable service at every location.
