Before & After Photos

Venkat contacted us after identifying elevated radon levels in his home and requested mitigation options with transparent pricing. After a thorough assessment, we designed a cost-efficient soil gas mitigation system to create consistent negative pressure beneath the slab and reduce radon intrusion.

Because aesthetics was important to him, we routed the discharge piping along a corner gutter to help it blend seamlessly with the home’s exterior.

The result is a discreet, professionally installed system that significantly lowered radon levels and improved indoor air quality without compromising curb appeal.

This home was pre-plumbed with a passive radon system during construction. We completed the activation by installing a high-performance radon fan, manometer, and radon system alarm, converting it into an active radon mitigation system. This upgrade helps continuously vent radon gas from beneath the home before it can enter the living space.

Not every home with a passive radon system is ready to be activated with the simple addition of a fan. In this project, the homeowner contacted Triangle Radon Defense after elevated radon levels were discovered. During our inspection, we found that while the home included a passive radon vent pipe, key components required for an effective mitigation system were missing.

To ensure the system would perform properly, we created a suction pit beneath the slab to improve soil gas collection, installed a radon fan to actively depressurize the foundation, and extended the vent pipe through the roof after discovering it had been terminated in the attic. These modifications allowed the system to safely vent radon gas outside the home while maximizing its effectiveness.

With the system now professionally designed and activated, the homeowner can enjoy greater peace of mind knowing their home has a radon mitigation system built to current industry standards.

Anna was helping her father purchase a new home when elevated radon levels were discovered during the inspection, above the EPA’s action level of 4.0 pCi/L. Wanting to ensure the home would be safe before move-in, she contacted us at Triangle Radon Defense for guidance.

We walked Anna and her father through multiple mitigation design options, carefully considering both optimal air quality performance and the home’s visual appearance. After selecting the best solution for their needs, our team completed the radon mitigation installation promptly, ensuring everything was in place before move-in day.

Now, they can move forward with confidence, knowing the home’s indoor air quality is safer and healthier for years to come.

Dana contacted Triangle Radon Defense after a recent radon test revealed elevated radon levels in his home, even though a radon mitigation system had been installed several years earlier during the home buying process. Concerned about the safety of his indoor air quality, he reached out to our team for a professional evaluation.

Michael, our Radon Solutions Specialist, performed a detailed inspection of the existing radon mitigation system and determined the original suction point was poorly located, limiting sub-slab communication and reducing the system’s effectiveness. To improve radon reduction and overall system performance, we designed and installed a new radon mitigation system with a more centralized suction location to create better pressure field extension beneath the foundation.

To maintain the home’s curb appeal, we installed a black radon mitigation system and routed the vent pipe alongside the gutter for a clean, low-visibility appearance.

Now, Dana and his family can enjoy safer indoor air and peace of mind knowing their home is protected by an effective radon mitigation system professionally installed by Triangle Radon Defense.
