"George and his entire company were amazing! George sat down with us and explained every detail of the work, and left us with material that gave us an education on Radon itself. This was very helpful for many reasons.. The work itself was conducted in an effective, clean, respectful and thoughtful way by his crew., and he came by to ensure completion and satisfaction. The crew even helped us with something adjacent to their job for no extra charge. I cannot recommend this company enough!"

"I couldn't have asked for a better experience. I checked a few Radon companies and Certified Radon was the best. They seemed to be the most knowledgeable, had the best warranty/guarantee, and actually came in cheaper than some of the others. They brought my radon level from a mid-6 to less than 1 on the first test. If you need radon services I would highly recommend."

"I had them come and give me an estimate. Josh was very professional and respectful. He gave me a written estimate right away. I would love to get the work done but cannot at this time because it cost too much and I am on fixed income. They will be the first I will contact should I decide to have the asbestos removed."

Radon Detection and Reduction questions, answered by experts

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

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.

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.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.
