"A radon test of my basement showed Radon levels above the EPA recommendations of 4.0. I contacted Tim Hinojosa of Radon Technology Company who came out to my house and examined my basement. He carefully reviewed my basement and briefed me on the methods for reducing Radon emissions. He then sent me a proposal carefully explaining all the details that needed to be done and the price for the work. He even included the expected annual costs to operate the system. I accepted the proposal. He and a coworker arrive right on the agreed time and date and went to work. Tim worked in the basement and his coworker worked outside. They were a real coordinated team. In about 3 and 1/2 hours they were done. The installation was very neat and everything was cleaned up. Tim left a Radon measurement device in my basement which was read several days later as 1.9. I was very pleased with the work and the results."

"They were easy to deal with and installed the system exactly as they described. We have yet to test the new radon levels, but have been assured it will work."

"Everything went well with them. I was very pleased with the job he did. I paid $90 extra for radon detection as well. Scheduling went well. I called him to set up the appointment. He was able to accommodate with my schedule. He was informative and explained what he was doing. This was the best home inspection I have had. I would definitely use him in the future."

"I wanted to have the fan for a Radon mitigation system installed in the attic area above my garage, but knew that access from my basement to the garage would require routing of the mitigation pipe above a dropped ceiling in the finished portion of my basement. Only two of the four companies that I'd contacted were willing to quote a garage attic fan installation, and SWAT Environmental's quoted cost was lower than that of their competitor. As a consequence, I suggested that SWAT send a representative to review my installation to ensure that the cost that they'd quoted for a garage attic fan installation wouldn't need to be adjusted. SWAT's representative, Jayme, arrived at my home at the scheduled time, reviewed the installation and agreed that a garage attic fan installation could be accomplished for the quoted price, but indicated that I'd have to call the office to schedule an appointment because his schedule (and those of other installers) was already booked. I called and was able to schedule an appointment for Jayme to perform an installation a couple of weeks later. Despite a later than expected arrival, Jayme was able to complete the majority of the installation (pipe routing, wiring and fan installation) before he had to leave. He returned to complete the installation (cover and seal the sump pump pit) about a week later when a second appointment could be scheduled. I initiated the post-mitigation Radon level test with the kit that had been left with me a week after the mitigation installation was completed and ran the test for five days. The report from the test lab indicated that the radon level in the "living space" area of my basement had dropped from a high reading of 8 pCi/L (in pre-mitigation tests) to 1.2 pCi/L and this post-mitigation value was confirmed by comparison with a Radon monitor that I'd purchased through amazon.com that indicated a "long-term average" of 1.24 pCi/L for the same five days. It's apparent that the Radon mitigation effort in my home was successful. I'd have no concerns about recommending SWAT Environmental to others for Radon mitigation."

Radon Detection and Reduction questions, answered by experts

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

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.

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.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.
