Commercial Cleaning Across Berkeley and West Berkeley
For more than three decades, ISLAS Maintenance has kept research labs, life-science offices, professional suites, and educational facilities clean, healthy, and presentable. Berkeley's mix is exactly what we're built for — the university-anchored R&D ecosystem around UC Berkeley and LBNL, the synthetic-biology and life-science firms clustered in West Berkeley, and the offices and studios along Fourth Street. Occupied space needs dependable upkeep regardless of the market, and we tailor a cleaning program that fits your space, your hours, and your safety and compliance standards.

Janitorial Services Built Around Your Facility
No two facilities have the same needs, so we don't use a one-size-fits-all checklist. Whether you need nightly janitorial service for a professional office, careful cleaning around a research or life-science workspace, or recurring floor care for a lab-adjacent facility, we build a schedule and scope around your operation, your hours, and your standards. Berkeley clients count on us for consistency, attention to detail, and a team that treats their facility like it's our own.
Why Berkeley Businesses Choose ISLAS
We've spent three decades earning long-term relationships rather than chasing one-off jobs — many of our clients have stayed with us for ten, fifteen, even twenty years. That loyalty comes from showing up reliably, communicating clearly, and being responsive whenever something needs extra attention. When you work with ISLAS, you're partnering with an established company that understands research and life-science environments and has a long track record of keeping demanding facilities at their best.
