When it comes to mold removal cost, there are a number of elements that will influence how much you pay. In contrast to mold in the shower, a severe mold growth can readily pose a health threat while also corroding the structure on which it is developing. Also, your mold removal cost will fluctuate depending on whether or not the crew needs specialized equipment and protective gear to get rid of the mold. Fungi is capable of inflicting significant harm to your house, as well as a wide range of frightening health hazards that you do not want to subject yourself to.

The more serious the mold growth, the worse the situation. This will also drive up the overall mold removal cost. Working directly with a mold removal expert company is the best method to get this problem repaired since they have the knowledge, experience, and tools needed to safely and efficiently remove the mold from the area. They’ll also seek for the source of the mold to avoid it from recurring, and they’ll attempt to control it to prevent it from spreading and causing structural damage.

Due to the wide price range, it can be difficult to budget for mold removal costs. However, this is a vital undertaking that you cannot postpone since the longer you wait, the more expensive and harmful to your health it becomes. This is why we’ll go through some of the variables that may impact the overall mold removal cost that you may use to decide whether or not this is a project you can afford.

Mold Removal Cost Per Square Foot

The typical mold removal cost per square foot ranges from $15.00 to $30.00 or higher. Mold typically fills a whole space, many companies will charge by the square foot depending on whatever section of your property has mold, such as your bathroom or basement. A smaller and more confined location, such as a crawl space, has less square footage, it will be less expensive to repair than a bigger room. The following is a rough estimate of the mold removal cost per square foot:

  • 50-Square Feet – $750 to $1,500
  • 100-Square Feet – $1,500 to $3,000
  • 150-Square Feet – $2,200 to $4,500
  • 200-Square Feet – $3,000 to $6,000
  • 300-Square Feet – $4,500 to $9,500

How Location Influences Your Mold Removal Cost

Mold has the ability to take root and grow anyplace in your home. Because of how hard and extensive the job is as a whole, the location will have a direct impact on the mold removal cost you spend.


Mold removal for your air ducts will cost between $2,000 and $6,000 on average. To eliminate mold from your air ducts, the company will have to do a specific cleaning, which is one of the most expensive mold removal methods. Condensation and moisture buildup might develop if the filters are not changed correctly. This is especially true if you do not get your system maintained and vented correctly. To avoid the spread of mold spores, turn off your HVAC system as soon as you see it.


You may expect to pay between $500 and $7,000 for mold removal in your attic, so you have a wide pricing range. The ease of access and the size of your attic will all play a role. Many attics have insufficient ventilation, which makes them ideal for mold development, as well as poor insulation, which can lead to condensation or moisture problems. You’ll have to remove and replace your insulation if the mold gets into it. Your labor costs will skyrocket as a result of this.


It will cost between $500 and $1,500 to remove any mold from your bathroom. Mold will most likely develop in your sink, bathtub, shower, drains, or on the walls if you have a leak if your bathroom isn’t properly ventilated. The best mold removal option for this place is air scrubbers, but the cost can skyrocket if mold grows in tough places such under your vanity, sink, or tub.

Crawl Space

Mold in your crawl area might cost anywhere from $500 to $2,000 to remove. Crawl areas, like basements, will grow mold for a variety of reasons, including increased humidity levels and a tendency to be moist. Due to the fact that this is a much more confined and smaller location, mold removal costs are often cheaper. They also have greater airflow, which can help mold develop more slowly.


The cost of mold removal in the basement often varies from $1,500 to $4,000. Basements are prone to floods, leaking plumbing, and high humidity levels, all of which favor mold growth. Mold may grow in your basement’s walls, wood, and insulation. The mold generally takes up between 100 and 300 square feet of your ordinary basement’s 1,000 square feet. Scrub any damaged areas, dry the space with a dehumidifier, and clean the air with an air scrubber to eliminate any mold spores.

Mold Removal Cost in Your Whole House

Finally, if hazardous spores or mold are found throughout your house, mold removal cost ranges from $10,000 to $30,000. The cleanup process is included in this estimate, as well as the cost of repairing any water damage. Consider replacing your windows if you want to keep mold from forming in the future. You may also improve your drainage system and pay attention to the ground around your house’s foundation. You’ll include the expense of replacing carpets, drywall, or other home goods in your final pricing estimates.

Mold Removal Cost of Materials

Your mold removal cost might range from $2,000 and $20,000 depending on how much damage the mold created before you discovered it and took action to remove it. These charges include the labor expenditures as well as the removal and repair of any surfaces. You might include the following:

  • Drywall Repair – $1,000 to $2,500
  • Fix a Leaking Roof – $350 to $1,250
  • Flooring Repair – $200 to $500
  • Install New Carpeting – $750 to $2,500
  • Seal the Foundation – $2,000 to $6,200

Mold Removal Costs for Labor

The typical cost of professional mold removal is between $500 and $7,000. The majority of individuals pay between $1,500 and $3,500, with supplies accounting for 40% of the cost and labor accounting for 60%. A smaller enclosed room, such as a crawl space, will cost approximately $500. The procedure might take a few hours, but it can also take many weeks. The cost of the job will be determined by the extent of the damage, the amount of mold, and the kind of mold.
