Photo Album: FAILED! - New Radon Mitigation System in Middletown, DE

These photos show a "new radon mitigation system" installed jin July 2022. The problem is, there was no post installation test done to see if the system was functioning as it was intended. Testing done 18 months after the installation of the new system, in January 2024, showed radon levels at 9.9 pCi/L, more than twice the action level recommended by the EPA.

This new home had a radon system

Radon system installed in July 2022, failed to do its job properly.

Unsealed Crack in basement floor/foundation wall joint

A radon system cant do its job if cracks like this allow air to leak underneath the slab. Shoddy, incomplete work done.

Vent Tube

About the only thing the Inspector found to be in compliance with this system was the use of 4' pvc pipe.

Depressurization fan gauge

This gauge shows the fan is sucking - but unfortunately the leaks in the basement floor render the depressurization completely ineffective in removing the radon from underneath the basement floor slab.
