Although no homeowner wants to increase cancer risks for family members, many people neglect to test their homes for radon, an invisible, odorless, cancer-causing gas that emanates from soil and rocks. Contacting a radon mitigation specialist to perform a radon test, or conducting your own test with a DIY radon test kit is the first step in protecting your family from hazardous levels of radon gas.

Oregon radon testing and radon removal

Certain areas of Oregon are known for having higher radon levels, such as NW Oregon, including the Columbia Gorge and Willamette River Valley. While radon exposure is considered a concern in these areas, it is also just as likely in any other OR location. Even two homes side by side can have drastically different radon levels, so it's extremely important to have your home tested for radon regardless of where you live.

The good news is, your beautiful Oregon home does not need to fall victim to the effects of radon gas. We at National Radon Defense want to help purify your home and maintain your home's healthy radon level.

No indoor environment is safe until a radon test has been completed and, if high levels of radon are discovered, a radon mitigation system has been installed.

That's why the team at NRD wants to help homeowners like you to maintain a healthy radon level in your home. Radon is a serious problem, and we're the best-trained radon experts in your area!

We Provide:
  • Radon testing

    When Jace came to our home to give us a bid, I felt that he was very knowledgeable. He got our estimate to us quickly, with options that we ended up using. Delphino's crew did a great job. He consulted me on the time that worked best for our schedule for the 2 day job. They were very considerate during their time in our home.

    We were very impressed with how committed John's was with doing a very thorough job. They went above and beyond the job and our crawl space has never looked better. Great team of guys. We would highly recommend this installation crew to anyone with water issues in a crawlspace. I was impressed by the clean up job and their commitment to doing a top quality work.

    Jake presented a good plan, which avoided problems that certainly would have occurred with the plan presented by your competition. I took careful notice of the reviews on Angie's List, and call some of the references, which were supportive. Finally, I chose Johns as a company that had been in business for some time and had extensive experience installing the basement waterproofing system. The guarantee was an extremely important factor in my decision, and John's track record suggests that it will remain in business and stand by the guarantee should problems occur. This was the best part of the project. Delfino and his crew (Francisco, Aaron, Ceasar) worked incredibly hard, were polite and considerate, and provided what appears to be a good installation. I give them my strongest recommendation. How they managed to hand carry 6 yards of broken concrete up out of that basement in the time they did is beyond me. John's employees spoke highly of the company, and the benefits offered. It sounds like a well run business. Please note that the system was installed in Central Oregon at our second home on the Deschutes River, where we are dealing with a high water table issue in summer. As of this writing, the water table is nearing its summer level, the sump pumps are working, and the basement/crawl space is dry.

    John's Waterproofing came out and encapsulated my crawlspace two years ago. When I decided it was time to finish my basement, they were the only company I called. Throughout the process the crew has been very respectful, clean and thorough. They made sure that my entire basement was sealed off and covered in plastic so that they did not get dirt or mud anywhere in my basement during the process. Manuel answered my questions when I had them and did not mind when I popped my head in to check on their progress. I was very happy with the work they did. Now the space fits with the rest of my finished basement.

    AJ & crew, Paul & I would like to thank you, for a pleasant and professional experience, doing our waterproofing. The “crew”, actually made us laugh, with their singing and chatting to one another. We have “never” experienced people enjoying their jobs, as your crew does! Or is their way, of keeping their sanity, in that dark hole!! Kudos to you and your crew for giving us, such, a great experience. We would recommend you “highly” Paul & Rosemary Willhite

    We want to thank you and your crew for the intensive work put forth in our crawl space. The workers put in three long days of dirty, sweaty, claustrophobic work down there and left it looking like the grandkids could play in it! Ok, kidding there! We appreciated the care they took in shielding with heavy plastic the area around our crawl space entry in order to keep dirt and dust from our living area. And what may seem trite but was a plus to our ears one floor above them was that the men always seemed happy to be at their work. Ramon kept us informed of every step and was a real comfort to us when we had concerns about this or that. We can't praise him high enough. Thank you all!!!!

    We first called TerraFirma but the salesman said we could dig out the entire exterior, add a membrane, drains etc for about $24,000. When I pressed for other ideas he seemed unenthusiastic. I said I would think about it and he never contacted me again. We then tried another company who was at least amenable to other approaches and gave me a quote of $12,000 for a sump pump and interior perimeter drains. Then we called John's Waterproofing and Peter came out. Peter was awesome. He had a whole suite of things that could help out in the basement and really listened and discussed our options. We weren't going for a dead dry basement that we could finish, we just wanted to get it dry and lower the humidity. So Peter and I went through all the things and came up with a plan together. In the end, we had a sump pump, perimeter drains in the basement and crawlspace, clean space barrier throughout the crawl and bright space paneling on the walls of the basement to stop humidity coming in from the walls. We also had piping installed below ground outside in which to run the gutters out to the street. All of that for only $8000. Once agreed the crews came right on schedule and finished the work ahead of time. I've waited to give a review to see the system in action. For the past week, it has been raining steadily. However in our basement is nothing but dry dust. Description of work: Our house is at the low point along several blocks and so our half basement/half crawl have always had problems with water intrusion. When it's not raining the basement has been humid and damp feeling, when it's raining the basement has had puddles of standing water. That has also caused the house to feel damp. We needed to dry out the basement and run water from the roof away from the house.

    Recently we contacted your company for an estimate to replace our vapor barrier and had the good fortune to have Jacob Bilyeu come to our home to perform the evaluation for these services. Jacob was friendly courteous, efficient, very professional and extremely easy to deal with. Due to the comfort level, we felt with him as your representative, we elected to proceed with John's Waterproofing Company to perform the work. We provided Jacob with an 800$ check as down payment for the scope of work and he scheduled a date for the work to be completed. The service team arrived today, May 3rd and comprised of Mike, Daniel, and Rodney. What a great group! They took special precautions to protect our floors, walls, and doors by covering them with plastic, and, like Jacob Bilyeu, the three of them were friendly, proficient and gave us a feeling that we were definitely in the hands of professionals that know their trade and would execute the work to the highest standards. At the conclusion of the work, they also did a great job of clean-up and left the work area spotless. Our compliments go out to you "John" for hiring staff/personnel of the high standards exhibited by the four aforementioned individuals-they were excellent and represented your company in a manner in which you can be proud. If we are ever asked to recommend a company to provide services of the nature of those performed by your company, we would not hesitate to suggest a call be placed to John's Waterproofing Company.
