Is Mold Inspection A Bigger Threat Today, Or Is It Just The Media

How Much Does Mold Removal & Remediation Cost?

The average cost of mold remediation is $2,325, with most homeowners spending between $1,500–$3,150 or $15 to $30 per square foot. A small mold removal job costs an average price of $500–$1,500 while a larger job costs around $3,000–$6,000. If the moldy area is 10 square feet or less, you can handle the job yourself for about $50.

In some cases, mold remediation costs can escalate to tens of thousands of dollars if the mold has spread and the problem is severe. Mold mitigation costs vary depending on how much and where mold exists. Broken down, mold removal professionals charge $75–$108 per hour.

Factors affecting the cost of mold abatement include how early the mold is detected and treated. If untreated for too long, additional costs mount because repairs of damaged drywall, lumber, subflooring, siding, and other potential areas might be warranted. The damage that needs to be addressed alongside the mold can increase costs by $5,000 and beyond.

Average Mold Remediation Cost Per Square Foot

Professional mold removal costs between $15 and $30 per square foot. The average cost for mold mitigation in a 100 square foot room will run $1,500–$3,150.

When mold growth becomes an issue in your home, you will need to consider three main categories of related expenses when looking at the final cost:

The cost of testing for and identifying the location and type of mold.

The cost of cleaning, remediation, and removing the mold, and of addressing the cause.

The cost of restoring affected materials if they were damaged or removed.

Mold Information for Home Tenants

The landlord or home owner must respond within seven days and has 30 days to repair the problem.   Mold contamination greater than 10 square feet requires a DOEE licensed mold professional to assess (evaluate) and/or remediate (fix) the problem.  Mold contamination below 10 square feet can be addressed by a non-licensed individual

The best way to prevent mold growth in your home is to control moisture indoors. However, where mold has already grown, it is important to take precautions to protect human health

Mold Assessment and Remediation Regulations specify requirements when addressing mold in indoor residential properties. These regulations establish a licensing program for mold assessment and remediation professionals who perform work

If there is at least ten square feet of indoor mold growth in a residential area with tenants, all assessment and remediation must be performed or supervised by a mold professional that is licensed by DOEE, and

No person may represent himself as a mold professional without the corresponding license from the DOEE,  and

All licensed mold professionals must notify DOEE of projects in accordance with the regulations, and follow performance standards and work practices required by the regulations.


If you are dealing with a mold problem in your home, EPA mold remediation is necessary in order to completely get rid of the mold spores that are present. The process of home mold remediation is intensive, and it is important that you follow specific cleanup procedures. Failing to follow the proper protocol is a problem, and you want to make sure that you and your family are safe from the health dangers that can occur as a result of mold.

Keep in mind that there are different protocols depending on the type of mold and where it is located in your home. Certain steps need to be taken for each type of building material, so it is a good idea to consult with a mold specialist before moving forward with the mold cleanup.

What is EPA Mold Remediation?

“EPA mold remediation” is the guidelines that the U.S. Environmental Protection Agency (EPA) has published in order to protect people from the dangers of mold exposure. Many people don’t realize how serious mold can be, and health problems can occur because they don’t follow a proper home mold remediation process.

Learning about the EPA’s guidelines for mold can help you to identify the supplies and techniques that are needed to effectively clean up the area and completely get rid of the mold. If you follow the steps as outlined, then the mold spores will be killed and you will be able to prevent future mold problems.

According to the EPA, you should not attempt a mold cleanup yourself if the mold covers more than 10 square feet, if the mold was caused by contaminated water, if the mold has gotten into the HVAC system, or if you have health issues that can be affected by additional exposure. You should hire a professional mold removal contractor.

Do-It-Yourself vs. Professional Cleanup

Even though you may want to clean up the mold on your own to save money, it is important to be aware of each necessary step so that you can understand the time and equipment that is needed to safely and completely remove the mold. Don’t make the mistake of cleaning up the area without the right equipment, because it will most likely result in the mold spores moving to other areas in your home. Mold will return in the future and continue to spread if it is not cleaned up correctly.

Guide for Professional Mold Remediation

procedural standard for the remediation of mold damaged structures and contents. The ANSI/IICRC S520 is based on reliable remediation and restoration principles, research and practical experience, and attempts to combine essential academic principles with practical elements of water damage restoration for technicians facing “real-life” mold remediation challenges. The S520 and R520 are written for use by those involved in the mold remediation industry, and is the result of collaboration among microbiologists and other scientists, public health professionals, industrial hygienists, remediation contractors, restoration service companies, cleaning and restoration training schools, trade associations that service the professional restoration industry, allied trade-persons and others with related professional and practical experience.

Guide is published as two separate documents: the standard itself and a supplementary reference guide. The procedural standard is supported by the reference guide. The intent is to use the principles outlined in the reference guide as a tool to better understand and apply the standard itself. However, the reference guide is not considered part of this standard.

The S520 Consensus Body Chair is Jim Pearson and Vice Chair is Scott Armour.

The S520 Consensus Body is currently working on revising the 2015 edition of the Standard. The revised Standard is expected to be available for public review by the end 2020.

What’s Missing With Mold Remediation Guidelines

Size matters more than you may think. Your ruler won’t help you understand.  You have to consider the limitations of what can be seen with a light microscope versus an electron microscope.   Consider a common occurrence after remediation.  People complain more after remediation that before remediation.  This was announced at an ACGIH symposium for mold remediation almost a decade ago.

described the contradictory data from a CDC NIOSH study at a hospital where pulmonary function was tested for hospital personnel and sampling of the moldy environment.  Remediation followed ACGIH recommendations in their book, Bioaerosols:  Assessment & Control.  Environmental test results were good but pulmonary test results were worse after remediation.  Their main environmental sampling was air samples for culturing and spore traps.

polymerase chain reaction or PCR was new to the industry.  Environmental Relative Moldiness Index or ERMI did not exist at the time either. ERMI is a statistical score applied to PCR testing from a common carpet cassette previously used for allergen testing. This is the only commercially available to test for small fragments of mold.  Other methods rely on whole spores or conidia while have extremely limited information for species level or ability to reproduce in culture for species identification.

Here we are a decade later and nothing has changed in the industry.  The industry still largely follows asbestos abatement techniques because it is human nature to resist change.  The industry still relies on the spore trap air sample as the test of choice to test for invisible mold or perform post remediation verification after mold remediation.  I have a case where 3 different firms have done mold remediation by the classic methods and the property owner is still having symptoms that lead to having mold remediation done. This is unacceptable.

Air samples are very questionable if pay attention to scientific literature.  Depending on the source (ACGIH, AIHA, Bob Brandys), you need to take anywhere from 3 to 9 samples per room for any statistical certainty since particles do not mix in the air like gasses and vapors.  You will easily spend more money on lab fees for the correct number of spore trap air samples than it costs for a single ERMI test.  The cost will explode if you want to use culturable air samples that can be identified to species level and take 2 weeks or more for analysis.
