"All Colorado Radon Mitigation Inc did an excellent job! The gentlemen that performed the work took extra care to make sure that the routing of the PVC was done correctly and still achieve the Radon level was going to be below the 4 pCi/L level that EPA requires. They did a very good job with putting the vent in the roof correctly and making sure that no leaks would come from their work. The Radon level that I recorded prior to their work was 15-17 pCi/L and now its down .3-.4. So yes they know what they are doing and they do it very well!"

"Affordable Radon Services, LLC was great. We had an unusual, BIG radon problem. They fixed it efficiently, cheerfully and competently. They had to come back a couple times to get the number way down. They did that right away, and made it good, with no extra charge. They were on time, and knowledgeable."

"Gage from Custom Radon Mitigation Systems did an amazing job installing my radon mitigation system. Upon arrival, he determined the best location in my mechanical room where to install the system, provided a timeframe for completion, kept me apprised of where he was in the process and informed me on how the system ran. Before the installation, my radon levels in my finished basement were routinely well above 4.0 pCi/L with a high of 14+ pCi/L. Since installation and checking for a few days, my radon level is often below 1.0 pCi/L and no more than 1.5 pCi/L. I'm very pleased with the system and Gage's professionalism. I sleep better at night knowing that my RadonEye device won't be setting off an alarm 2-3 times a day now. If you're considering a radon gas abatement system, I highly recommend Gage and Custom Radon Mitigation Solutions."

FAQs for radon gas abatement projects in Berthoud, CO

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
