The old-money heart of the western San Gabriel Valley, northeast of downtown LA — home to Caltech, the Rose Bowl and some of Southern California's best-preserved early-1900s architecture. Craftsman bungalows, lath-and-plaster walls, period plumbing and the crawl spaces and basements rare elsewhere in the region are exactly where slow, hidden moisture turns into mold.
With Rose Bowl, Old Pasadena, Caltech close by, Pasadena is a short run for our crews — roughly 10 min out. We take on mold testing for homes and businesses here, and you get the figure in writing on the spot, once a technician has had eyes on the actual damage.

We draw air and/or surface samples, run them through an accredited lab, and translate the findings into plain English — and where the numbers call for removal, we lay out precisely what that would involve.
