How Much Does Mold Remediation Cost in Los Angeles? [2025 Data]

In the City of Angels—and everywhere else—mold is a villain. But luckily, homeowners can cut it from the script. Between coastal fog rolling into Venice, leaky pipes in Spanish-style bungalows, and the occasional Santa Ana wind pushing moisture where it doesn’t belong, mold sneaks onto the scene like an uninvited guest at a Hollywood afterparty. 

On average, mold remediation in Los Angeles costs $2,573, with most homeowners paying between $1,590 and $3,850. Costs depend on the mold’s type, size, and hiding spot, whether it’s a bathroom cameo or an HVAC blockbuster.

Mold Remediation Cost Factors 

Los Angeles, CA, has a mix of challenges that attract spores, starting with the climate. From humid coastal air to cool, damp mornings, mold finds plenty of opportunities to thrive, whether clinging to bathroom grout or making a grand entrance behind drywall. Also, older craftsman homes and stucco apartments don’t always have modern ventilation, so spores can turn a hidden leak into a long-running problem before you notice the musty smell.

Black mold is especially notorious in LA because it loves hiding where water damage has gone undetected, like in hillside homes with drainage issues after rare but heavy rains. And with high housing prices, many properties get quick fixes instead of long-term solutions, leaving behind the perfect stage for mold to return.

Mold Location

It costs more to remove mold from some regions of your home than others. For instance, mold growth in hard-to-reach areas, like in your HVAC system or drywall, can require more time and materials to remove than mold in very accessible areas, driving up costs.

Mold Infestation Size

Most mold removal professionals charge around $11 to $27 per square foot. So, if you're removing mold from a 100-square-foot area, you can expect to pay around $1,000 to $2,500. But factors like the location of the growth and the type of mold can affect how much it costs to remove it. 

Mold Inspections and Tests

Mold inspection costs between $326 and $1,170. Mold testing is key to determining whether you have the presence of mold in your home, plus the extent of the infestation. You’ll need to hire a mold inspector to test surface samples in your home before moving forward with remediation.

Mold Type

Regardless of how it affects remediation costs, you need to know which type of mold you have in your home for your safety. That said, if a mold test reveals the presence of black mold, your mold remediation pro will likely charge more to remove it based on the additional cost of protective equipment.

Damage Caused by Mold

If left untreated, mold can damage your drywall, carpeting, and flooring. Replacing or repairing your walls or floors will add costs to the removal.

Here are some cost estimates for different types of mold damage repairs in Los Angeles, CA:

Mold Remediation Pro Costs

Hiring a mold remediation pro in Los Angeles can be costly, nearly 9% higher than in other metro areas. The overall cost of living in LA is about 50% higher than the national average. While mold inspections and remediation labor are tax-exempt, building materials, including drywall, flooring, or sealants, are taxable. 

Labor costs run higher in LA due to insurance, licensing, and certification requirements that ensure the work meets local codes and guidelines. These protections are excellent for homeowners, but they do raise the price. If a contractor is required to remove walls, ceilings, or floors, your project may need permits, which can increase the project’s cost.

Tipping

In Los Angeles, tipping isn’t mandatory but is often appreciated. For smaller mold jobs, homeowners might tip crews $20 to $50, while significant, multi-day projects can see tips of $100 or more. It’s a way to show gratitude in a city where service workers already face steep living costs.

Additional Pros to Consider Hiring 

Bigger mold jobs in Los Angeles often require more than one specialist to prevent mold from making an encore appearance. A mold remediation specialist may loop in a crawl space encapsulation pro, who will seal off damp areas under older homes in neighborhoods like Echo Park. Expect your crawl space encapsulation cost to cost $5,500 on average.

A roof repair contractor is your superhero for patching​​ leaks in Spanish tile or flat-roofed homes and preventing heavy rain from dripping inside. Homeowners can expect their roof repair costs to hover around $1,150, but some repairs can cost significantly more. You'll need a foundation specialist for hillside homes prone to water intrusion. Foundation repair costs can range significantly from $2,225 to $8,125.

Does Mold Remediation Increase Home Value?

Mold remediation in Los Angeles doesn't just save your lungs; it saves your home value. Your dwelling's energy efficiency will improve, since many remediation jobs include sealing leaks or improving airflow, which lowers future maintenance costs. Plus, spaces you once avoided in your home, like musty basements or bathrooms, can finally be put to work again without worry.

And don't forget the aesthetic upgrade: Patched walls, fresh paint, and clean finishes replace the unsightly, shiny, slimy stains mold leaves behind. Lastly, when it's time to sell, remediation proves its worth by removing one of the biggest red flags from inspection reports.
