Our home inspection revealed high levels of radon so we hired Decon to mitigate.
From consultation to installation, Nelson and his team were excellent! Very knowledgeable and professional.
They reduced our levels from 7 to less than 2.

Decon was a recommendation from friends who were very happy with their radon mitigation system. They presented me 3 options for remediation and I opted for a sub-slab ventilation system.

Decon was a recommendation from friends who were very happy with their radon mitigation system. They presented me 3 options for remediation and I opted for a sub-slab ventilation system. It's super quiet and keeps radon levels very low inside the house. The recommendation in Florida is to keep it below 4.0 pci. In Europe the recommendation is below 2.0 pci. My radon level inside the house is 0.5 pci now. Very pleased with the result!

Thank you, Mr. Bornia. As a radon mitigation company who has been in business for 38 years, we pride ourselves on not only successful mitigation but satisfied clients. We are pleased that you are happy with the install. Let us know if we can be of any assistance in the future.

We recently discovered our home had incredibly high radon levels, which was incredibly stressful. We hired DECON Environmental for the remediation, and they were fantastic from start to finish.
Right from the initial consultation, they were completely transparent about the process, the timeline, and the costs, no hidden surprises. When it came to the actual installation, the team was highly professional. They took great care to protect our home while working, leaving everything spotless.
Most importantly, the system works perfectly; our once dangerously high radon levels are now down to a very safe, low number. If you want a company that does the job incredibly well and treats your home with respect, look no further than DECON. Highly recommend!

The installation was done professionally, and after the initiation of the system, it required several additional steps and visits to complete what I needed: a quieter air flow and control of the timer. It took additional visits to get everything worked out and the results showed a minimal amount of Radon with the fan at half speed, the timer at 12-14 hrs/day and the opening of the air duct without any screen.
Response from the owner · 4 months ago
Thank you for your detailed review and for trusting us with your radon mitigation project.
We appreciate your patience throughout the adjustment process. Every home is unique, and achieving the ideal balance between effective radon reduction, airflow comfort, and system operation sometimes requires fine-tuning after installation. We were happy to make the additional visits necessary to ensure the system performed to your expectations.
We're pleased that the final setup achieved minimal radon levels while operating at reduced fan speed, with the timer optimized to your needs and the airflow adjusted for quieter operation.
Your feedback is greatly appreciated, and we're glad we were able to customize the system to meet your specific preferences while maintaining effective radon reduction.
Please don't hesitate to reach out if we can be of assistance in the future.
