Family-owned. Proven. Stronger than ever.

ALG Building Maintenance is a family-owned and operated commercial cleaning and building maintenance company, proudly serving San Francisco and the Bay Area since 2003.

With 23 years of continuous operation, we’ve built our business on reliability, long-term client relationships, and consistent results.

Today, ALG operates under new management. Strengthening an already established company with renewed leadership, higher standards, and sharper execution.

We work exclusively with commercial properties—offices, multi-tenant buildings, gyms, and professional facilities.

Our teams operate under supervision, clear expectations, and performance-driven processes.
