Ensuring Radon Safety in Schools

The Drennen Custom Contracting Advantage

Children are at a significantly higher risk of developing cancer from radon exposure—about 20 times higher than adults. This makes it crucial for school districts to work with a state-licensed and nationally certified company to ensure thorough and accurate radon testing, keeping students and school staff safe. Drennen Custom Contracting, a leading radon expert in Colorado with over 50 years in business, is the go-to partner for radon testing and mitigation.


Drennen has tested thousands of classrooms across multiple school districts in addition to over 15,000 homes. All of Drennen's radon measurements meet or exceed the Environmental Protection Agency's standards (EPA 402–R–92–014), and the company holds the necessary state licenses and national certifications through the National Radon Proficiency Program (NRPP). Drennen is also a member of the American Association of Radon Scientists and Technologists (AARST).


Drennen's reports on radon measurements are clear, accurate, and reliable, thanks to our stringent quality control measures. For precision, we deploy blanks and duplicates during each test, and our lab and testing equipment are calibrated to meet state and national requirements.


Our in-house laboratory and owned short-term testing equipment enable Drennen to offer the most accurate, affordable, and timely results. We can also place and retrieve test equipment after school hours, minimizing disruption to teachers and students.


Drennen's expertise in radon goes beyond testing. We have mitigated numerous schools using conventional sub-slab and sub-membrane depressurization methods, and we work with school district HVAC and mechanical teams to adjust systems, reducing radon levels and improving air quality.
