An affluent residential city south of Pasadena, home to The Huntington Library and large estate properties. Big homes with multiple bathrooms, irrigation and older copper plumbing see slab leaks and slow drips that can grow mold unseen in walls and under floors.
A short hop from The Huntington Library, Lacy Park, San Marino High School, San Marino sits about 12 min from our Pasadena base, so a technician gets there quickly. We do mold testing for houses and businesses across town, and you'll have the written estimate in hand on site — put together only after the tech has actually seen what's going on.

We collect air and/or surface samples, send them to an accredited third-party lab, and explain the results in plain English — then, if the numbers call for it, scope the removal that follows.
