Mold isn’t just unsightly — it’s a health hazard that can damage homes, schools, and businesses if left untreated. In California, where weather shifts between wet winters and hot summers, mold growth is a common problem for property owners. This guide from Alliance Environmental Services explains the cost of mold remediation, what the removal process looks like, and how you can prevent future outbreaks.
How Much Does Mold Remediation Cost in California?
On average, mold removal in California ranges between $1,500–$5,000, depending on:
- The size of the affected area
- Whether the mold is visible or behind walls/ceilings
- The type of building (residential vs. commercial)
- If asbestos or lead paint are also present
Alliance Environmental Services provides upfront assessments so property owners understand costs before work begins.
