It is important to understand the meaning of the radon results from your test, so we’ve posted this page for interpretation of the radon levels. Please check your report for the radon level, and reference the section below that applies. Recommendations for further action are noted in each item. Also, see below at the bottom of the page for more information about radon. If you are unsure about any of these results, or the interpretation of the radon level, please let us know.


0.0-1.9 pCi/L: This level of radon is below the EPA Action Level. No action is required at this time. Re-test every two years.

2.0-3.9 pCi/L: No action is required at this time. While no action is required at this time, this level is within the EPA “consider action” level of 2.0-3.9 pCi/L. This means that if you plan on making use of this level of the home (the level where testing was done) for livable space, and/or plan on spending 6-8 hours per day, every day, in this area, you should seriously consider the installation of a radon mitigation system. Re-test every two years.

4.0 pCi/L and above: This level of radon is above the EPA action level of 4.0 pCi/L. It is recommended by the EPA that this home be mitigated for radon to allow for a more safe level of radon exposure in the home. This home should be mitigated by a radon mitigation specialist. Consult with a mitigation specialist to design and install a radon mitigation system. After a system has been installed, the home should be re-tested to ensure the system is operating properly. Re-test every two years.


0.0-1.9 pCi/L: No action is required at this time. This also suggests that the radon mitigation system in place in the home is functioning as intended. Re-test every two years. 

2.0-3.9 pCi/L: No action is required at this time. While no action is required at this time, this suggests that the mitigation system that is in place is not functioning optimally. Ideally, radon mitigation systems should successfully bring the levels to below 2.0, even though that is not required. There may be issues interfering with the performance of this system. Consult a mitigation specialist to repair/optimize this system. Re-test every two years. 

4.0 pCi/L and above: This level of radon is above the EPA action level of 4.0 pCi/L. This suggests that the radon mitigation system is not operating as intended. This is a health hazard and needs repair. Radon mitigation systems can often be successful at bringing the radon levels to a very low level, most often below 2.0 pCi/L. We recommend that this system be evaluated and repair/optimized by either the radon mitigation system installation contractor that originally installed it, or by another certified radon mitigation contractor. Consult a radon mitigation specialist to repair this system. Re-test every two years.


EPA recommends re-testing every 2 years and/or if the soil surrounding the structure or the foundation is altered. We suggest hiring a certified radon testing professional for this testing.

Information regarding radon mitigation and information about contractors can be found here:

Here is a link to the EPA document, Buyer’s and Seller’s Guide to Radon: This document describes radon and radon testing methods for real estate transactions. 


You should consult with your mitigation system installer/contractor for information on how the system will work, what the costs are, what it will look like, and how it would be configured through the interior and exterior of the home. Feel free to consult multiple mitigators. If you have a block foundation, crawlspace, or any specialized foundation, or if the radon mitigation for the home is complicated by any other condition, keep in mind that that will result in additional costs for the system. This system will need to operate continuously. While it is not complicated typically to install a radon mitigation system, it should be carefully planned.

    Buyers Home Inspection

    Buyer’s Inspection

    Buying a home is likely one of the largest investments you’ll ever make. That’s why it’s so crucial that buyers understand exactly what they’re getting into. During a buyer’s inspection, we form a close partnership with the buyer. We’ll be your guide as we explain any property defects or issues we uncover. We’ll also answer any questions you have.

    Pre Listing Inspection

    Pre-Listing Inspection

    If you’re selling a home or property, it’s a good idea to have it inspected before it’s listed. Houses with a pre-listing inspection are more attractive to potential buyers. Pre-listing inspections give sellers the chance to work with us to uncover issues or necessary repairs. We’ll also give you our expert recommendations on what repairs to make before showing the property.

    New Construction Inspection

    New Construction HOME Inspection

    Before the final walk-through with the builder, a new home should undergo a new construction home inspection. We thoroughly search the home for building defects and anything that may have been overlooked during construction. This allows the builder to better prepare the home for its walk-through, which results in an easier and smoother move-in experience.

    11 Month Warranty Inspection

    ONE YEAR HOME Warranty Inspection

    Many newly constructed homes are sold along with a 12-month builder’s warranty that covers the cost of repairs associated with constructional defects. During a one year home warranty inspection, we help homeowners identify the repairs they should request before their warranty expires. This prevents you from becoming financially responsible for problems that should fall to the original builder.

    Re Inspection


    After a buyer’s home inspection, the buyer and seller of a home will come to an agreement about what repairs should be made before closing. Once those repairs are made, a re-inspection can be performed in order to ensure all agreements were honored and that the necessary repairs were made.

    Commercial Building Inspection

    Commercial Building Inspection

    During a commercial property inspection, we help buyers of commercial buildings better understand their potential new property before making the final purchase. Just like our home inspection services, we make sure that our commercial inspections are thorough and backed by our experienced & dedicated inspectors. We provide you with a detailed report that clearly breaks down our findings and recommendations.

    Additional INSPECTION Services – Offered Standalone or Bundled

    Radon Testing

    Radon Testing

    Radon is a radioactive gas that occurs naturally in soil. As radon rises from the ground, it can enter a home and build to dangerous levels. Exposure to radon can cause serious health problems. Detection is impossible without professional equipment. MKC Associates offers professional radon testing, either standalone or bundled with our home inspection services, to keep your home safe.

    WDO Termite Inspection

    WDI Inspection

    Although small, wood-destroying insects (WDIs), including termites, can cause major and expensive property damage. This damage can result in structural instability, which is extremely dangerous. During a WDI Inspection, we search the home thoroughly for signs of an infestation and/or damage from these creatures. We’ll also check for common contributing factors that attract WDIs, like excess moisture.

    Drone Inspection

    Drone Inspection

    In a situation where a roof’s pitch or material makes it unsafe to walk on foot, an aerial drone inspection can be used to collect high-resolution images of the roof so we can safely and thoroughly inspect for damages and defects. Drone inspections help ensure no stone goes unturned before going to closing.

    Infrared Thermal Imaging Inspection

    Infrared Camera Inspection

    Leaks, improper insulation, moisture intrusion, electrical hotspots, and other heating system problems can lead to damage and costly repairs. Our infrared camera inspection uses infrared cameras to help visualize & detect thermal energy in the home. This helps us identify areas of heat loss or excessive heat in all areas of the home. We’ll use that information to uncover problem areas and give you solution recommendations.

    Property Consulting and Diagnostic Work

    Property Consulting and Diagnostic Work

    Property owners and condominium associations deserve to know how to troubleshoot the common issues that affect a property. We offer property consulting and diagnostic work to give you a clear understanding of your unique property and the problems you’re dealing with. After our inspection, we offer our professional advice about remediation, maintenance, and repair.

    HOA Property Inspection

    HOA Inspection for Condo Associations

    We offer HOA Inspections for condominium associations who want to keep their building safe and well-maintained without having to inspect each individual unit. We thoroughly inspect the common areas of the property to determine if defects and damages exist. Keep in mind that we’re never here to “sell” you anything. We work for you to give you the tools you need to get proper quotes from contractors.
