“If I could give 6 stars I would! System 4 is the best Business Partner I have worked with in their field for almost 20 years. Joe and his team have been extremely responsive and flexible with us, even through the COVID-19 situation that has greatly impacted our company. You definitely get what you pay for with System 4.”    — Ryan I.

“Bay Alarm hired System4 in June of 2018. They handle all janitorial and handyman services for our corporate office and janitorial in our Santa Clara branch. I am pleased to say that the association with Bay Alarm has been very positive with great service, excellent communication and responsiveness to any and all feedback. They offer competitive pricing for their services and a high degree of integrity. I would recommend System4.”  — Tina P.

“I cannot recommend System 4 or Joe Z highly enough. I’ve contracted janitorial services to clean recreational facilities for over 20 years and am so happy to be working with Joe. If you have worked with overnight janitorial services you have no doubt experienced poor cleaning/service, poor communication, no shows and to top it all off contracts that are difficult to cancel. Working with System 4 has truly been a partnership with a company who cares about solving problems and providing a great service. They go above and beyond to get it right and we are so grateful to have found them. If you are looking for a janitorial company who really “gets it” and wants to exceed your expectations, System 4 should be your next call.”   — Leigh B.

“I run a medical clinic business with 3 locations. What I found most attractive about System4 is that I have one resource for all ofmy facility’s needs. In addition to regular nightly janitorial service, I have used System4 to arrange pest control, floor refinishing and a few other one-off needs. I negotiated our agreement directly with Joe, the owner. He was professional, transparent and fair. I can comfortably recommend System4.”    — Dan F.

“System 4 provides wonderful service. They have been very professional and helpful during these past few months of the pandemic, as we are an essential business. We have so appreciated their work to keep our office and employees safe and clean. Thank you everyone at System 4! Kim // BascoDrywall & Painting”    Kim B.
