Mold Air Quality Testing in Los Angeles: what's different here
Local homes
A massive variety of housing including historic Spanish Colonial Revivals, mid-century moderns, and modern high-rises. Many iconic neighborhoods were developed in the early-to-mid 20th century.
What we see in Los Angeles
While the climate is generally dry, coastal fog in areas like Santa Monica and poor ventilation in older apartments can lead to mold. Plumbing leaks in dense multi-family units are also a factor.
Neighborhoods we visit often: Silver Lake, Hancock Park, Echo Park, Venice, and every other part of Los Angeles and Los Angeles County.
