A cleaning company is the people it sends into your building after hours. Every other claim, the bonding, the years in business, the client list, sits on top of that one fact. This page lays out how Frisco Brothers Janitorial Service hires, screens, and supervises the crew that walks through your door, because if you are evaluating a cleaning vendor, this is the part you actually need to read.
The short version: every hire is background-checked and reference-checked, owner Mark McGlothlin personally approves each one, the company hires from the Frisco-area community rather than dispatching from a staffing pool, and supervisors run unannounced spot inspections on every active account. The longer version is below.
Background Checks and Reference Checks on Every Hire
Every staff member who steps onto a client site has cleared two checks before their first day. A formal background check covers criminal history. A reference check verifies prior employment, work habits, and the kind of detail that does not show up in a database: did they show up on time, did the previous supervisor trust them with keys, did clients ask for them by name.
Both checks happen before the offer is finalized. No exceptions, no provisional starts, no “we will get to it next week.” A candidate who has not cleared both has not been hired.
This applies to crew, supervisors, and floor specialists. It applies to family members on the team. It applies regardless of how good the references look on paper. The standard does not move.
Owner-Approved Hires
Mark McGlothlin reviews and approves every hire personally. That is not a rubber stamp. Mark reads the references, talks through the candidate with whoever ran the interview, and signs off before the person is added to a route.
What that means in practice: when a new face shows up at your building, Mark already knows who they are. He has reviewed the references, he has approved the hire, and he is the one accountable if the placement does not hold. There is no anonymous HR department between the owner and the people in your facility.
For a building manager handing over after-hours access, that is a different proposition than signing with a franchise location. The owner of the company is the same person who decided this crew member could be trusted in your space.
Local Hiring, Not Contractors
Frisco Brothers hires from the Frisco-area community. The crew cleaning your building lives nearby. They are not contractors pulled from a regional staffing pool, not gig workers booked through an app, not subcontracted out to a third-party cleaning vendor with their own hiring standards.
This matters for two reasons.
First, retention. A local hire who likes the work and is treated well stays. A staffing-pool placement rotates. The cleaning industry runs on high turnover, and the standard response is to accept it as a cost of doing business. Frisco Brothers does not. Most crew members are with the company for years. Some have been here for more than a decade. The crew showing up at your building this week will, in most cases, be the same crew showing up next year.
Second, accountability. A crew member who lives in the area and has built a career with a local company has more on the line than a placement filling a shift. Their reputation is local. Their references come from local employers. The work follows them.
The trade-off is that hiring takes longer. Mark turns down candidates who would clear a staffing-pool screen. The result is a smaller pool of people who actually fit the standard, and they tend to stay.
Supervisor Spot Inspections
Hiring well is the floor, not the ceiling. Quality after onboarding requires checking the work, not assuming it.
Victor and Ana Ayala, the field supervisors, run unannounced spot inspections on every active account. Each brings more than 20 years of field supervisory experience, with 200+ staff managed between them at prior employers. They are bilingual in English and Spanish, which matters for crew supervision and for clients with Spanish-speaking staff.
Inspections cover the work the crew actually performed against the contract scope: restrooms, high-touch surfaces, floor work, trash, supply restock, the spaces that get cut when a crew is rushing. The crew does not know which night a supervisor will walk the building, which is the point. The standard holds because someone is checking, not because someone is asking.
Mark also runs spot inspections directly. Both owners are personally active in cleaning client facilities, which means they are in client buildings regularly, not only when something has gone wrong.
When an inspection turns up something off-standard, the conversation happens with the crew that night or the next morning. The fix happens before the next service date. Clients do not have to call about the same issue twice.
First-Day Onboarding
A new hire does not get unsupervised access to a client site on their first day. Onboarding pairs the new crew member with a supervisor or an experienced lead through their first visits to each account they will service.
That walkthrough covers the building layout, access protocols, the contract scope, the products used, and the specific quirks of the account. Every building has them: the door that needs to be checked twice, the alarm code sequence, the supply closet that locks, the office that does not get vacuumed when the partner is working late. Those details get walked through in person, not handed off as a checklist.
The new hire goes solo on an account once the supervisor is satisfied that the work meets standard and the building is fully understood. For larger or higher-sensitivity accounts (medical offices, churches with weekend access, daycare centers), that ramp is longer.
Why This Matters to Buyers
The hiring and inspection process produces three outcomes that show up in the work.
Consistency. The same crew shows up week after week. They learn the building, they spot what changes, they catch the small things the contract did not specify but the manager actually cares about. A rotating crew never reaches that level of familiarity.
Accountability. When something is missed or something goes wrong, the chain of responsibility is short. The crew member is known, the supervisor is known, the owner is the one who hired them. There is nobody to pass the call to.
Lower turnover, fewer surprises. A facilities manager who has dealt with cleaning vendors before knows the pattern: the first month is great, the third month is fine, the sixth month has new faces and the work has slipped. The hiring standard described above is built specifically against that pattern. Twenty-five years of client retention is the proof, not the claim.
