A small, tree-lined city between Pasadena and the Arroyo Seco, full of historic Craftsman and Victorian homes. Period construction, original plumbing and finished basements mean hidden damp is common — exactly the kind of moisture that feeds mold behind the walls.
A short hop from Mission Street, Arroyo Seco, Mission Gold Line Station, South Pasadena 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.
