  • About Radon in Delaware

    High levels of radon have been found in neighborhoods across Delaware. Radon testing and radon mitigation have become more prevalent in the past few years due increased awareness of the impact radon gas has on the air we breathe in our homes and workplaces. Homeowners, realtors, builders and municipalities are issuing guidelines and regulations across the country encouraging testing and mitigation of radon in homes and businesses in Delaware.

    At SWAT Environmental, we are committed to protecting family, friends and neighbors in Delaware from radon exposure.

  • SWAT Environmental Reviews

    Jonathon F. – Great job. Very easy to schedule. They came out the next week and had the job done in a few hours. You could tell the tech knew what he was doing. He said he had been doing this multiple times a day for years. Very glad I found them on the web!

  • Proven Mitigation Solutions

    Sub-slab depressurization systems are the most widely installed mitigation approach. A certified technician creates a suction point beneath your foundation, then installs a vent pipe extending above the roofline. An electric fan draws gas from below the structure and safely expels it outdoors before it can enter occupied spaces.

    Our systems operate continuously to maintain negative pressure beneath your foundation, helping minimize the risk of radon infiltration. Post-installation testing confirms effectiveness and documents a reduction in indoor radon concentration.

    Radon mitigation systems are typically low maintenance, but annual or regular inspections can help confirm that the system continues functioning properly.

  • Choosing Certified Radon Professionals

    As the largest and most experienced radon mitigation company in the U.S., SWAT Environmental brings national expertise and certified technicians to homes across the country. We follow recognized radon industry standards and maintain affiliations or certifications connected to the American Association of Radon Scientists and Technologists (AARST), doing business as the Indoor Environments Association (IEA), the National Radon Proficiency Program (NRPP) and the National Radon Safety Board (NRSB).

    Our technicians receive ongoing training to stay current with best practices and system design techniques, so our solutions are backed by up-to-date industry knowledge.

  • Frequently Asked Questions

    Check out these common questions and answers to learn more.

    Does Delaware have high radon levels statewide?

    Delaware shows variable radon potential across its three counties. While New Castle County contains identified high-risk zones, both Kent and Sussex counties regularly produce elevated test results. Approximately 15.4% of Delaware radon tests reach or surpass the 4.0 pCi/L action threshold.

    Individual property testing remains necessary because neighboring homes can show different concentration levels based on construction methods, foundation type and soil conditions.

    How long does a radon mitigation installation take?

    Most residential radon mitigation system installations are completed within 4 to 8 hours in a single visit. The timeline depends on your foundation type, home size and whether the system requires interior or exterior installation.

    Our technicians work efficiently to minimize disruption to your daily routine. After installation, you’ll need to wait 24 to 48 hours before conducting a post-installation radon check to verify the system’s effectiveness.

    Will homeowners insurance cover radon remediation expenses?

    Standard homeowners insurance policies typically exclude radon mitigation from coverage since radon presence is considered a naturally occurring environmental condition. Some insurers offer optional radon endorsements as policy add-ons.

    Review your specific policy or contact your insurance representative to confirm coverage. Most property owners pay mitigation costs directly as a health-protective home improvement investment.
