What is the Cost for Removing Mold from my Crawl Space?

Read Time: <2.5 minutes

If you’ve noticed or been told there is mold in your crawl space, you’re probably wondering how much it will cost to remove it. There are a few factors that go into how much it costs to remove mold from your crawl space.

What factors affect the cost of mold remediation?

  1. Size of the crawl space. The square footage of your crawl space is probably the biggest determining factor in the cost of mold remediation. The larger the space, the more labor and materials are needed to complete the job.
  2. Height of the crawl space. The height determines the speed at which our crews can complete the job. If the height is really low and the technicians are having to crawl around instead of stand up and walk around, the longer it will take them to remove the mold. On the other hand, if the ceiling height is high enough that a ladder is needed to reach it, it will also take more time and contribute to the cost.
  3. Is there insulation and what kind? If you have fiberglass batted insulation in your crawl space, it has to be removed for mold remediation. We follow the guidelines from the Institute of Inspection Cleaning and Restoration Certification (IICRC) on porous, semi-porous, and non-porous materials. Batt insulation is a porous material, meaning that it has tiny openings that could be harboring mold spores that could not be seen with the naked eye, so once it is exposed to mold, it must be removed from the crawl space.
  4. What is the severity of the mold? If the mold in your crawl space is a mild case and only a few mold spores are visible with no wood decay, we follow the IICRC guidelines for damp wiping with a mild, environmentally friendly detergent solution. If the mold is widespread and covers the majority of the wood, it may require a more extensive treatment such as soda blasting.

Just a note of warning when you are getting estimates for mold removal. Some companies will estimate based on “spraying” the mold. If a company talks about “spraying for mold”, that is a tell tale sign that they are not actually removing it. Spraying mold will kill the surface, but it will not kill the spores that adhere to hard surfaces. There are only a few ways to effectively remove mold and wiping it down with a detergent solution to remove those spores is one of them, however simply “spraying” is not. The EPA also notes that dead surface mold cells are still a known allergen and can cause health issues in susceptible people.

How much will it cost to remove mold from my home?

So what is the average cost based on the above factors? Insulation removal and disposal runs between $0.60 and $0.80 per square foot. Replacing the insulation will run between $1.45 and $1.65 per square foot depending on the type of insulation and R-value. The actual mold removal runs between $2 and $2.50 per square foot.

For illustrative purposes, if you have a 1,000-square-foot crawl space with batted insulation, it will cost somewhere between $4,050 and $4,950 to remove the old insulation, remove the mold, and replace the insulation.

We hope this helps you plan for the cost of mold removal in your crawl space. If you are unsure if you have mold or the extent of the problem, we are always available for free consultations in the Charlotte area.
