What Is Mold Remediation?
Mold remediation involves the removal and elimination of mold from an area. Mold can grow where moisture and organic material co-mingle with at least 60% humidity. Depending on the mold remediation method used, the process can include containment where the area is isolated to prevent the spread of mold spores.
Mold removal specialists will treat mold with a biocide, remove unsalvageable pieces and properly dispose of them so that mold spores do not circulate. The stained area typically gets treated with a spray to eliminate mold. Some mold removal specialists will also deploy a fog through your HVAC system to eliminate any lingering spores in your home.
The affected space will need time to dry and must remain undisturbed for at least 24 hours. Some mold removal processes can include treating affected wood with a primer and repainting with a paint that has mildewicide to prevent mold from returning.
Typical Mold Remediation and Removal Costs
Mold remediation and removal costs vary because of a number of factors. The extent of the damage will dictate the cost the most, as mold removers can charge per square foot. The method of mold removal can also impact the cost as some mold removal companies use different strategies to combat mold. The location of the mold can change the cost because different spots in the home can mean different removal methods.
By Square Foot
Some mold removal companies will charge around $2.50 per square foot while other estimates range between $10 and $25 per square foot, including materials and labor. Costs can vary if the mold removal technicians use containment, which means additional materials. Costs can increase should the specialist need to remove drywall or other affected items that cannot be repaired.
- Basement mold removal: A 1,000-square foot basement can cost between $500 and $3,000, depending on the size of the mold problem. Basements tend to have more damp areas than other rooms so it has greater potential for mold to spread. Costs can compound if mold has gotten into drywall or if the basement wasn't properly encapsulated.
- HVAC ducts mold remediation and removal: Some mold removal companies will clean HVAC ducts to eliminate mold after cleaning an affected area since the HVAC system can continue to blow spores around your home. Duct cleaning can cost between $300 and $700. Some removal companies can instead fog the ducts to remove the mold that might exist there, which can get charged per square foot.
- Attic mold remediation: Removing mold from an attic can range from $1,000 to $7,500, depending on the issue. If the mold can get treated, the cost will remain lower, but should any insulation need replacing, the costs can rise.
- Crawl space mold remediation and removal: Crawl space mold remediation and removal can cost between $500 and $4,000, depending on the size of the mold problem. Any mold issue with a crawl space can mean looking at the ventilation to prevent humid conditions for mold to grow, plus any structural items will need inspection to see if they need repair. Crawl space insulation can cost between $3,000 to $8,000.
- Bathroom mold remediation: Most bathroom mold removal and remediation can cost from $500 to $1,000, but if the mold has spread behind things like tile or a vanity, costs can increase significantly to the tune of $10,000 or more for a bathroom remodel.
- Whole-home mold remediation and removal: Whole-home mold remediation costs can range from $5,000 for a 2,000-square foot home up to as much as $30,000 in some cases. Mold specialists usually classify mold problems by levels with level three being the worst and requiring the most remediation work.
