"Lance and his crew showed up right on time, explained clearly what they were going to do, and answered all of my questions. After the installation was completed, they cleaned everything up, so there was nothing I needed to do afterwards. I realize that every house is different, and radon mitigation results will vary from house to house. Also, my house had ideal conditions for a good radon mitigation outcome - a 4 inch gravel bed under a basement concrete slab with no cracks or other places radon gas could enter from below. Having said that, my radon levels before mitigation averaged 4-6 pCi/L, with occasional peaks to 10-12 pCi/L on some days. After mitigation, the levels have been below 1.0 pCi/L since installation 2 weeks ago. Needless to say, I am very pleased with the result. I would not hesitate to recommend Lance and his crew for any work you might need for your home."

"Amazing! Fernando was really helpful. He looked at our job, and helped us navigate an erroneous elevated radon level due to the weather. He saved us in a situation where we would have spent a thousand without solving anything. Thank you. Your guidance and engagement was very helpful."

"I had a problem with the water pressure fluctuating. Come to find out, it was the holding tank. The professionals at Waterdrct came out (Dennis) promptly and found the tank was old and waterbound. They were like lightening (in a good way) and had the tank replaced in like 30 mins. These guys are GOOD !!! The water pressure was more than I thought the well could produce. Excellent job and very informative. They are true professionals !! I highly recommend them."

FAQs for radon gas abatement projects in Sherman, CT

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.
