Weather, and a high-water table, earthquakes can break pipes, compromise roofs, and disturb existing waterproofing systems—creating the perfect storm for hidden mold infestations.
With frequent coastal fog, humidity, and occasional water damage, mold can grow unnoticed in homes and commercial buildings, leading to health risks and structural damage.
Many residents assume that staying indoors keeps them safe from pollutants—but in reality, indoor air can be two to five times more polluted than outdoor air, especially in older apartments and homes.
From foggy coastal neighborhoods to older properties in the Mission or Marina Districts, the city's damp climate and aging infrastructure make it a hotspot for mold growth.
