Radon Mitigation in Maine

About Radon in Maine

High levels of radon have been found in neighborhoods across Maine. 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 Maine.

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

SWAT Environmental Reviews

Jaime N. – Such a professional company! I was incredibly pleased with Tommy and James as a spectacular sales team and certified radon specialist. I was amazed at how quickly and efficiently they got the technicians out to several of my properties. As a realtor, I will use them for all of my future properties. I even had the pleasure to follow up with Becky and the owner, Adam. I couldn’t speak more highly of a company and recommend them
above anyone else.

Effective Radon Mitigation in Maine

Active soil depressurization delivers proven results for properties testing above action thresholds. Installation involves drilling through the foundation to create extraction points beneath the building. A dedicated ventilation system with continuous fan operation pulls radon from below ground, expelling it safely above the roofline.

System performance depends on proper design matched to your foundation type and soil characteristics. Post-installation verification testing confirms the system achieves target reduction levels.

Professional Credentials Matter

When selecting a radon remediation company, look for affiliations and 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). These credentials help show a technician’s competence through standardized testing and ongoing education.

As the largest and most experienced radon mitigation company in the U.S., SWAT Environmental brings national expertise and certified technicians to local properties. We maintain industry credentials with AARST/IEA, NRPP, and NRSB and follow recognized radon mitigation standards on all projects.

Frequently Asked Questions

Learn more from these frequently asked questions.

How common is radon in local homes?

Radon appears frequently in Maine properties, and elevated levels have been found across the state. Individual results vary dramatically even between neighboring properties, so every Maine home warrants testing regardless of age, construction type or neighborhood history.

How effective are radon mitigation systems?

SWAT Environmental’s professionally installed systems reduce radon levels by up to 99%. Our certified technicians design each installation to match your property’s specific foundation type and soil conditions. After installation, we equip you with a follow-up testing kit to verify that your system is effectively reducing indoor radon concentrations.

With proper maintenance and regular inspections, these low-maintenance systems can continue supporting long-term radon reduction.

Does Maine require radon testing for real estate transactions?

Maine law does not mandate radon testing during property sales, though sellers must disclose known radon information and existing test reports. Many buyers still request testing during inspection periods. Real estate professionals frequently recommend testing to avoid transaction delays. Sellers benefit from proactive testing, which lets them address concerns before listing and can streamline negotiations.
