Indoor Air Quality Testing FAQ

Common questions about indoor air quality testing in DMV.

Testing is a good step if you notice musty odors, excess dust, or allergy symptoms that get worse indoors. Northern Virginia homes with crawl spaces, older ductwork, or recent water intrusion are especially good candidates for testing.

We test for mold spores, VOCs, particulate matter, carbon monoxide, allergens, and humidity-related contaminants. Samples go to an accredited laboratory so results are based on real data, not visual estimates.

Yes, testing before you close gives you documented evidence of what is in the air you will be breathing. Northern Virginia's mix of older homes and energy-efficient new construction each carry different contamination risks.

Yes, many pollutants like mold spores, VOCs, and carbon monoxide are invisible and odorless. Professional testing is the only way to confirm what is actually present in your Northern Virginia home's air.

Yes, the region's humid summers raise moisture levels that promote mold growth, especially in crawl spaces and basements. Tightly sealed homes also trap pollutants that would otherwise escape through natural air exchange.

You receive a written report with your laboratory results and specific recommendations for your Northern Virginia home. That report gives you a clear action plan to address any contaminants found.

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!
