About Us
A Katy, Texas janitorial contractor serving commercial, medical, and industrial facilities across greater Houston since 2006.
Who We Are
A contractor built around one standard.
MGS Supply & Services maintains commercial, medical, and industrial facilities across greater Houston from our base in Katy, Texas. A dedicated crew is assigned to each site and held to the same documented protocol on every visit.
The work is built on EPA-registered chemistry and objective verification — ATP bioluminescence testing confirms a surface is clean at the microbial level, not to the eye. QA results are recorded and reported, so a lapse is identified before it reaches your desk.

How Leadership Operates
The principles behind the work.
Verifiable, not assumed
Cleaning is only as good as it can be measured. Every site is scored against a documented QA protocol and reported back to the client.
Accountable by design
A dedicated crew is assigned to each facility and answerable for the result — no rotating subcontractors, no handoffs.
People first
The standard lives with the crews who execute it. They are vetted, trained to protocol, and supported to hold the line.
Why MGS
Why facilities standardize on us.
Most contractors staff by availability. We assign a dedicated crew to each site, accountable to the same documented protocol on every visit — so performance stays consistent, and consistency stays verifiable.
Compliant by Design
Every product carries EPA registration; every crew operates to OSHA standards. In regulated environments — surgical suites, laboratories, food-adjacent spaces — compliance is documented, not assumed.
Verified, Not Assumed
ATP bioluminescence testing confirms a surface is clean at the microbial level, not merely to the eye. A failed reading triggers re-cleaning before sign-off. UV-C and electrostatic disinfection are deployed where the risk profile warrants.
A Measured Track Record
100-plus facilities maintained across commercial, medical, and industrial portfolios — each scored against recurring QA audits and reported back to the client.
Response, Around the Clock
A line staffed 24/7 for spill, flood, and biohazard events. Facility risk does not observe business hours, and neither does our response.
