If you need help to correct a radon problem in your home or business, Advanced Radon Technologies is the company to go with! When I first began googling radon remediation companies in my area, the SWAT company appeared to be the most logical choice (the search seemed to indicate that they were local). We called them and they promptly responded and sent technicians to our home within a few days. But, boy, what a frustration and disappointment that proved to be! After nearly three years of dealing with SWAT to try and convince them that their system wasn't doing the job, the team at Advanced Radon finally came to our rescue! And the kicker is that SWAT charged us nearly $2000 for a system that was flawed from the start; Advanced Radon's experienced team helped us trouble shoot our problem and find a solution that didn't cost us any more money! They spent a lot of time in communication with us, visited our home to be sure we were squared away, and never charged us a penny. These are some quality folks who know that they're doing and genuinely have their client's best interest in mind. If you want a more detailed account: Four of our kids live in our basement and our radon numbers were around 14. The SWAT company responded quickly by sending a technician who openly told us this was his first job on his own. He didn't dig a sufficient pit in our foundation to create enough air movement. When we re-tested the basement, the numbers were still over 4. They eventually (weeks later) sent another technician out who assessed the situation and told us the pit should be bigger. He dug it out and went on his way. The numbers were still too high... back to 9 or 11, I believe. After waiting several months for SWAT to have a technician in the area again, they came back again and sealed the pipe in the floor with silicone, assuming the lack of a seal was the problem, hereby pulling air from under our foundation but then releasing it into our basement. We waited probably another year and tested the system again... ridiculously high this time: 45+. This was just unacceptable. It took months again for SWAT to return my calls and stop giving me the run-around and send someone out. They decided to put another hole in our floor and try to get a better result that way. They also charged me $200 more for this, even though they advertised that they guaranteed results. We paid it, realizing it was getting ridiculous, how many times they were having to drive out to us. Even after the second pipe was installed, the system wasn't working. If our windows were all open most of the day, our numbers dropped to about 8. Compared to 45, that was good. But it was still double the recommendation. Something had to be done to actually fix this- and it was clear to us that SWAT was just incapable of helping us. Finally we began to call around to other Radon companies outside of our area to hopefully get some wisdom and guidance from them. After talking with the folks at Advanced Radon, we knew we had a great resource. They exchanged probably 20 or 30 different emails with me, and spent multiple hours on the phone with me, helping me through trouble shooting the problem. They understood the unique properties they were dealing with and identified what was going wrong with my system (a very unusual situation with the location of the radon source) just from a diagram of the basement and two different sets of test results. I was amazed at their extensive knowledge and the easy solution they provided. The most encouraging aspect of dealing with Advanced Radon is how apparent it is that they Really Care about helping people get rid of the radon. They are passionate about doing the job right and offering people peace of mind that their homes are safe for loved-ones. Thank you, Thank you, Thank you Advanced Radon Technologies, for giving our children a safe place to sleep at night and giving us the peace of mind that the problem is finally fixed! Save yourself a lot of time, anxiety, stress, and money and just call them first. They'll do the job right, the first time and guarantee their work. I can't recommend them highly enough! *It has been several months since they helped our family and our radon numbers are consistently lower than 1. Absolutely amazing! read more

I was getting ready to sell my house, and because of the age of my home and experience my neighbors had had with radon mitigation, I decided to test my my house for radon. I had no idea how to get the test, so I googled radon companies. Advanced Radon sounded like someone who knew what they were doing so I requested a test. They sent one out right away. After recieving the results, I realized if I wanted to sell my house, I would have to get the work completed. The owner of the company came out shortly thereafter, to give me a quote. He was so knowledgeable about the process and what would be involved. I felt very comfortable working with this company. They came out a couple of weeks later and installed the system. They tried to find the best spot to place the pipe outside, so it would not be so visible. I am very happy with the work completed by Advanced Radon, price was reasonable, and I would highly recommend them to everyone! read more

Dave first off cares about his customers health and well being. He is interested in solving your Radon issue and making sure the work is high quality. He pulls proper permitting for electrical and his support team is awesome. The other Radon company that was used did not meet specific standards in doing Radon mitigation work. Do your homework and read reviews before hiring a Radon company and check certifications: https://nrpp.info/. Dave takes his profession seriously and has a tremendous background in this work. Dave and his team are highly recommended! Also, make sure you understand guarantees, a fan guaranty has no relation to a Radon reduction guarantee. Advanced Radon is the only company I would use for Radon mitigation period. Dave really helped me in a pinch and made sure things were done to code and spec. read more

I just purchased a new home and in my inspection I paid for additional Radon testing. The test came back above recommended levels and so I got estimates to fix. Advanced Radon beat everyones bid and were extremely helpful with information. The person on the phone walked me through all the things I needed to do to fix the home (instal moisture barrier, floor insulation, open crawl space vents) that will adjust the radon level. He suggested I retest after fixing a few things and then call him back in a few months. To me, this it top notch customer service. He spent over 30 minutes on the phone with me and encouraged me to do things that may end up in them not even getting business if I can get the radon down. This company is honest and Good people! If I can't get my radon level down, I will be coming back! read more

After measuring some concerning radon levels in our home in fall of 2022 we phoned owner David M. Gerard, Advanced Radon Technologies, Inc. located in Spokane Washington. Mr. Gerard generously spent over a half hour answering all our questions, described how and when exposure to radon becomes concerning, and pointed us in the direction to gather more radon measures in our home to determine what, if any, mitigation steps to take. The information he related was clear, substantial, and extremely helpful. Our worries about exposure to radon have been greatly decreased and we feel confident in the plan we have to move forward. We strongly recommend this highly experienced professional and look forward to working with him in the future. read more

We had just moved in, and had open boxes all over the basement, and we were supposed to get a 48 hour notice from the landlord of service personnel entering our home, but they just showed up and we said OK...shame on us. We were still inventorying our stuff a couple days later and discovered a large sum (our cash savings to purchase a car which we desperately needed) was missing. We cannot prove the guys from this company stole our "car jar," but as they were the only ones other than ourselves in the house, it is a VERY strong probability that they stole it. The owner was dismissive when we called and asked about it and said his crew wouldn't do such a thing. We don't buy it. read more

Smooth experience all around. Owner brought a binder showing his vast experience, his patented invention, past federal contracts, etc. - he's even an instructor in radon technology. I'm careful, so later I googled him to verify much of that, and confirmed it's true. Bid was competitive (a neighbor had received three quotes including his), and installation was efficient - they started with a dropcloth even on the stairs which was appreciated. He even started by shoveling snow out of my driveway! Radon levels did go down appropriately in the expected time - a month later. read more

I would give Advanced Radon my highest endorsement. I have worked with Dave Gerard for nearly twenty years and he has installed systems for me personally and for countless clients of mine. His prices are always consistent, but more importantly, he is a long-standing and reputable business owner in the community and has a deep knowledge of issues related to Radon and an unmatched commitment to the industry. Additionally, I have found his staff to be professional, friendly and detail oriented. read more

Amazing service from start to finish. They obviously know what they're talking about when it comes to radon, and they don't hesitate to share that knowledge. The install process for our new radon mitigation system was very neat and tidy, and the contractor who was sent was pleasant to work with. They also provide a radon test kit so you can check the results - we just got ours in, and we're down to a safe and healthy level! read more

WARNING!!!!!! The workers that put a system in our home stole from us! We called the owner of the company thinking he would want to know about this, but he instead responded rudely. As I look back now, I remember some odd behaviors from the workers...they became real jumpy at one point. Now I know why. The system may work fine but I would NEVER AGAIN allow these people on our property! CALL SOMEONE ELSE!!!!! read more

Advanced Radon Tech put two systems in our home, and did a great job. They showed up on the day and time they said they would, with their PPE for Covid, and completed both systems in one day. All work was professionally done, with tarps to protect our floors and carpets. I would definitely recommend them to anyone needing a system installed. Much thanks to all involved! read more

Dave did an excellent job of explaining the technology, and quickly replacing the dead motor in the existing mitigation system. I would use the company again, but I doubt that I will need to. Very service oriented. read more

Dave did a great job for us. Very knowledgeable and very thorough. Would highly recommend to anyone with Radon concerns!
