The Pennsylvania Department of Environmental Protection estimates that approximately 40% of Pennsylvania homes harbor high levels of radon. It is a serious health issue that should be taken into consideration during every real estate transaction.

We understand that there are many details involved with a real estate closing. Sellers are anxious for a trouble free transaction and buyers need assurance that they are purchasing a home where they will be happy and healthy. The representatives at SWAT Environmental of Pennsylvania are well trained to assist realtors and their clients in understanding radon and the best ways to remedy any residential radon issue. We are the largest radon mitigation company in Pennsylvania and provide services to all 67 counties.

The radon experts at SWAT Environmental always recommend that radon be addressed as early in the real estate sales process as possible. Time must be allowed for initial radon testing, mitigation system installation, and for follow-up testing to be completed. If radon levels are high, it can take time for the levels to drop following a mitigation system installation. You can help guarantee that your closing takes place as scheduled by taking remediation steps early.

Testing and mitigation is highly recommended for home sales by the Environmental Protection Agency, The American Society of Home Inspectors, and the US Surgeon General. The Federal Housing Administration (FHA) and Housing and Urban Development (HUD) require that radon tests and mitigations are completed prior to a real estate transaction. While Pennsylvania does not require testing or mitigation at this time, it is strongly recommended by the Department of Environmental Protection.

Taking a proactive stance against radon can put you one step ahead in the process of selling a home. Providing a buyer with peace of mind that any radon issue has been addressed can be a positive selling point. At SWAT Environmental, all our technicians are licensed by the Pennsylvania DEP, certified by the NRPP, and are company employees. We do not use subcontractors or day laborers.


Performing a radon test is the first step in the radon mitigation process. A test can be conducted by a homeowner with a simple do-it-yourself radon test, or by a certified radon measurement professional. Many home inspectors can conduct these tests as part of their inspection process. A do-it-yourself test is accurate and affordable (approximately $20). Hiring a measurement professional may yield quicker results and will cost approximately $150.

You’re ready to buy or sell a home and you’ve learned that the radon level is above the recommended safe level of 4.0 PCi/L. Radon mitigation systems are very effective in bringing radon down to acceptable levels. These systems function by removing the radon gas that has accumulated below the foundation via a vacuum system and venting it above the roof. The cost of a radon mitigation system is similar to any moderate home repair (approximately $800 - $1200).

It’s important to note that radon mitigation systems are not “one size fits all”. However, the best system for a home can be determined based on a few facts about the structure. Call SWAT Environmental of Pennsylvania for quick, over the phone estimate on the installation of the appropriate system for a home. For an accurate quotation on radon mitigation, a realtor or homeowner should be prepared to provide the following information:

  • Current radon level
  • Age of the home
  • Size of the home
  • Was interior piping for radon installed during construction?
  • Basement construction material (stone, concrete, cinder block)
  • Is the basement finished?
  • Have there been additions put on the original home?
  • Does the home have a sump pump and/or French drain system?
  • Are there any crawlspaces?
  • Are there basement areas with exposed soil or gravel?

In most instances, an accurate assessment of the radon mitigation needs can be made when this information is provided. Our sales representative will be happy to explain the mitigation process thoroughly and answer any questions. At the time of installation, the technician will do a site assessment with the client and review the installation procedure. You can learn more about radon mitigation systems by viewing the technical information provided here.

Occasionally, a home will require a pre-mitigation site evaluation. These would include very large homes or homes with multiple foundation levels and/or additions. The representatives at SWAT are trained to recognize when a home requires a technical site visit and will make that recommendation as needed.
