An unincorporated foothill community just north of Pasadena, below the San Gabriel Mountains near Eaton Canyon. Older homes, steep lots and storm runoff off the foothills make roof leaks and crawl-space moisture — and the mold that follows — a recurring problem here.
A short hop from Eaton Canyon, Christmas Tree Lane, Farnsworth Park, Altadena 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.
