Mold Air Quality Testing in Richmond: what's different here
Local homes
Features a wide range of housing from historic Point Richmond cottages to mid-century suburban developments and newer waterfront homes. Much of the core was built during the WWII boom.
What we see in Richmond
Coastal winds and moisture from the bay can cause dampness in older, poorly sealed homes. Industrial areas may also have older drainage systems that contribute to ground moisture.
Neighborhoods we visit often: Point Richmond, Marina Bay, Iron Triangle, El Sobrante, and every other part of Richmond and Contra Costa County.
