Radon Testing FAQ

Common questions about radon testing in DMV.

Yes, new homes in Northern Virginia can still have elevated radon levels. Construction type and local soil conditions affect radon entry regardless of a home's age.

Testing is conducted in the lowest livable level of your home, typically the basement or first floor. This is where radon concentrations are highest in Northern Virginia homes.

The EPA recommends taking action if your radon level reaches 4 pCi/L or higher. Protect The Investment, LLC provides a written report with your exact reading so you know where you stand.

Yes, radon testing is a smart step before closing on any Northern Virginia property. A documented test result gives buyers and sellers clear information before the transaction moves forward.

Yes, the EPA recommends retesting every two years even when a mitigation system is in place. Systems can lose effectiveness over time, and retesting confirms your levels remain safe.

Tory was a recommendation from our real estate agent - and what a great contact to have. Tory and Kenyatta came out the next day after being contacted, luckily for us because he had a cancellation and a chance opening. We (my partner and I) are first-time home buyers and have basically no idea what we are doing. Tory showed us around and explained everything in a detailed and easy to understand manner. He was extremely friendly, informative, and thorough. What sets this company apart from many others is that they don't charge for a re-inspection and they came as a duo - so you just have the one upfront charge and the inspection was reasonably quick. Tory took us through not just all of what they were evaluating, but through some information regarding basic home maintenance. He maintains his relationships with his clients and made us feel very comfortable about reaching out in the future with questions. We feel lucky that we had this inspector and can't recommend them more!

Tory and Tom were absolutely awesome to work with and will meet you at whatever your knowledge level is to ensure you feel comfortable in the conversation. They were super thorough and most importantly to us, practical in explanations and associated estimates. Really great guys you'll immediately trust and they are fantastic at what they do.

Tory and Protect the Investment, LLC are lifesavers!!! My contractors discovered some unexpected mold in my condo when completing repairs after a water leak. I called PTI and Tory was out at my property the next day. He and his team completed the remediation the day after the his initial assessment. He was prompt, professional, and affordable. I HIGHLY recommend.

I had an outstanding experience working with Tory for a home inspection on a single-family property. From start to finish, Tory was incredibly thorough and professional. The inspection report was extremely detailed, clearly outlining every issue that needed to be addressed, with supporting visuals and clear explanations. Thanks to the thoroughness of his report, we were able to successfully negotiate concessions with the sellers to address several major issues he identified — a huge win that added real value to the process. What truly stood out was the level of follow-up support I received. Tory made himself fully available to answer all of my follow-up questions, especially when certain things raised by the general contractor didn’t seem quite right. His input was instrumental in helping me choose the right contractor and avoid unnecessary work. If you’re looking for someone who’s detailed, accessible, and genuinely looking out for your best interest, I highly recommend Tory. You’ll be in good hands.

Tori was my home inspector on my first home (a major fixer upper!) Now after move in, I'm seeing his thorough inspection caught every single issue from structural issues, plumbing, electric, small leaks, roofing issues. He even noted issues with appliances that we are now seeing. We haven't found any issue he hasn't already noted in our report. We worked with him on multiple homes that we had put in offers for and his report helped us walk away from some beautiful- seeming homes that would have bankrupted us if we had foolishly not done a thorough inspection. His report was a great guide for electricians and plumbers on what to fix as we get the house into shape. And today when we called him for potential asbestos abatement inside a wall we opened, like always, he was prompt, comprehensive, and on it! Came within a day, took samples, and helped us by identifying clear issues we hadn't seen and even offering recommendations of other trusted contractors who can complete the work. I felt overwhelmed by his thoughtfulness and expertise to leave this review! We have 100% trust in Tori and have been incredibly lucky to have him as our first home inspector so we are able to call him for other work now. If you're doing your home inspection and not sure if hes going to check every out, he will! And more than that, he offers other services like asbestos and lead abatement that can help you trust as a homeowner that he's doing the right thing. The name feels right and I can tell he's helping us protect our house and investment!
