How Much Does Mold Remediation Cost?

If you have discovered mold in your home, it is important to act fast. Mold spores can spread quickly, causing destruction in their path. As mold continues to grow and spread, it can cause irreversible damage to a home and allergy symptoms in the home’s inhabitants. As DIY mold removal is rarely efficient, most homeowners rely on mold remediation specialists to get the job done right. So how much does mold remediation cost? This can vary considerably depending on where you live, the extent of the mold problem, the company you choose, and similar factors.

Mold Remediation

Average Per Square Foot

In the U.S., the average cost of mold removal is $2,325, according to HomeGuide. Most homeowners spend between $1,500 and $3,150, or $3.50 and $7 per square foot, on mold removal.

Smaller jobs can fall as low as $500 while more substantial cost of mold remediation can climb upwards of $6,000. If the mold problem is very extensive and affects multiple rooms, mold remediation cost can skyrocket to tens of thousands of dollars.

In addition to removing the mold and treating the affected area, homeowners should also consider the costs involved in making repairs to lumbar, drywall, siding, subflooring, and similar materials damaged by mold or moisture.

Common Spaces Affected

Mold can grow anywhere there is water, oxygen, and a food source. One of the most common locations of mold growth is the attic. From leaky roofs to poor attic insulation, moisture problems are frequently seen in attics. Treatment can cost $1,500 to $3,500.

Another common space affected by mold is the basement. Leaky pipes, high humidity, and overall dampness can result in mold growth. Mold removal in a basement costs an average of $500 to $2,500.

Poor ventilation and moisture in the bathroom can also lead to mold growth. You may also discover mold in your crawl space. Removal costs for either can range between $500 and $1,500 on average depending on the extent of the mold growth.

Mold Abatement Timeline

Mold removal involves a number of steps, starting from mold testing and ending with the removal and replacement of damaged materials. When you hire a professional to perform a visual mold inspection, the expert will look for signs of microbial activity such as moisture intrusion, water stains, and poor indoor air quality.

The time it takes to remove mold can vary considerably based on a number of factors, such as the extent of the problem and where the mold is located. If the mold is found in the ceiling or behind walls, the removal process will typically be lengthier and more costly.

On average, you can expect mold abatement to take between three and five days to complete. If a mold sample is sent to the lab for testing, you may have to wait several days to receive the results.

Fabric Mold

Removing mold from fabrics can be challenging. If you have clothing that has been affected by mold, place it in a sealed bag and throw it away.

More substantial pieces of fabric, such as curtains, may be able to be saved. Ask your local dry-cleaning establishment about cleaning your curtains. Be sure to bring them to the facility in a sealed bag to prevent contamination of other fabrics in the vicinity.

The dry-cleaning establishment may charge an extra fee for this service. Note that some mold stains may not come out of the fabric, so be realistic about your expectations.


When hot and cold air condense inside vents, it creates the perfect environment for mold growth. When the vents are in use, the mold inside the vents can become airborne and spread throughout your home. For this reason, it is important to turn off your HVAC system if mold is discovered.

Air duct and HVAC system treatment is required to remove harmful mold. This treatment can range from $1,5000 up to $3,500 due to the complex nature of cleaning air ducts.

If the amount of mold inside the ducts is extensive, it may be necessary to remove the affected air ducts and replace them with new ones. You may also need to have your heating and cooling units cleaned, which can increase the cost further.
