"Radon Stoppers did a great job installing a radon mitigation system in our home in Minneapolis. It was very straightforward to get an estimate and schedule the installation. Pat was happy to explain how a radon mitigation system works and where it would be installed. They guarantee that the system will reduce the radon to a safe level for the quoted price with no surprise charges, and also provide a 5 year warranty. We are very happy with our new radon mitigation system."

"Professional in every aspect. The owner, Walt Fitzmaurice, is very knowledgeable and took the time to explain what would be done and when. Top marks for communication, timeliness and quality of work. Easy, no pressure sale. Walt and his crew did an amazing job mitigating radon from our basement! Very respectful working in the house, and there was nothing for me to clean up after they left. All around a good experience. Walt left a measurement device to assess success of the mitigation. Radon level went from 5.8 pCi/L to < 0.3 pCi/L. Two visits (quote, installation) and it was done. Walt come to our house to look at how to route the system. He wasn't in a hurry and explained everything to me in layman's terms. On the day of the install, they arrived promptly, at 09:15 and explained what they were going to do. No electrical work was required. Existing outlet in attic from a 1985 project. The vent pipe runs from a basement store room into the attached garage and to the attic where the fan is located, the roof vent is on the back side of the garage and is not noticeable. You cannot hear any fan noise. The installation was finished by 2:00 p.m. I would highly recommend Advanced Radon Services."

"Robert was easy to get in touch with, and agreed to come by to stub a pipe into my draintile with very little notice.  He then came back to install the rest of the radon mitigation system, also spent over half hour discussing various aspects of home ventilation on the phone with me.  He did a clean, neat, professional job, although did leave me a number of small followup tasks to do.  Overall, a good experience."

"A+ It went great! Doug was early, and already had the out buildings inspected before I arrived. This left me time to focus on the home, which was the bulk of the inspection time. I really appreciated that, since I was on my lunch, and I am more concerned about the home than the other buildings. Doug was very thorough and explained why he would either flag or not flag an item. He explained what to look for when it comes to settling of a home, which eased my mind. It is also convenient that Doug has his own Radon detector. He set it up two days before the inspection date so we could review the preliminary results together. TEST FOR RADON! The price was very reasonable for something so important. It was high in this house, which is common for homes in MN and WI. I was then able to ask the owner to install a radon mitigation system."

FAQs for radon gas abatement projects in Cottage Grove, MN

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.
