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!

Peace of mind
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.

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.

The services were as expected, thank you for the good work
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.

I want to express my respect for Ramon and crew (Ivan and Casey)and how hard they work on our basement. I was impressed with their knowledge of the product and work ethic. They covered everything with plastic sheets and kept the work area clean and organized. We are waiting for enough rain and groundwater to test the installation. The Brightwall is so clean and white. Ramon did a masterful job of cutting and applying it to the formerly ugly, dingy basement walls. What a difference! The WaterGaurd system seems to be exactly what we were looking for. I highly recommend Johns Waterproofing and this crew of friendly, nice, and competent employees.
