Mold frequently becomes an issue in buildings, particularly in environments that are high in moisture. Its quick proliferation and expansion can cause harm to properties and pose possible health dangers. It’s crucial to comprehend the expense involved in eradicating mold so you can address the problem promptly before it escalates.

Removing mold from drywall costs $15 to $30 per square foot. Depending on the extent of the mold damage, you may need to consider replacing drywall in some sections.

The price can vary depending on multiple factors, including whether your drywall needs a repair or a total replacement. Other price considerations may include other materials, such as any leaking pipes that need to be replaced.

On average, mold remediation companies charge somewhere between $10 and $25 per square foot. For example, if the mold growth is across a 100-square-foot room, you can expect to spend between $1,500 and $ 3,150.

Normally, mold remediation companies will charge by square feet for small mold infestations. However, if the mold infestation covers a large space, they may need to charge you for the entire space.

Should I replace moldy drywall?

This will depend on the extent of the damage. Regular drywall does not like moisture, so if it has been wet for a longer period of time it may have warped or be beyond repair.

It is cheaper to kill mold than replace drywall, once the cause of the mold has been remedied, it might be worth replacing affected sections and starting fresh.
