"Project: Radon Mitigation I highly recommend Advanced Radon. 1. Advanced Radonâ s mitigation system decreased the radon in my house from 40 pCi/L to at or below 2 pCi/L within two days. 2. Advanced Radon guaranteed reduction of radon under 4 pCi/L (the industry standard). 3. Advanced Radon offered an effective product at a reasonable price. 3. The technicians showed up on time and worked diligently until the job was finished. We had agreed ahead of time on where the piping would be located so as to maintain aesthetics, and I am pleased with the results. 4. Advanced Radon offers radon testing before and after the mitigation system was installed to ensure success. 5. I was extremely impressed with the education level of the technician. He answered all of my questions throughly. He even had pictures and diagrams available to help explain the answers. As an engineer, he had patented several pieces of equipment to ensure a safe and effective installation of the mitigation system. Overall I was very impressed with Advanced Radon. I would highly recommend them to anyone struggling with high radon readings in their home. I feel confident that if I ever had a problem with the system, Advanced Radon would address it."

Radon Detection and Reduction questions, answered by experts

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.
