"Andrew's service was nothing short of superb. From the moment he arrived to the time he left, his professionalism was evident. His attention to cleanliness during the inspection was greatly appreciated, and his thoroughness in examining every aspect of our new home provided us with invaluable peace of mind.

He worked collaboratively with us and our realtor, playing a crucial role in negotiations to ensure our home was in the best shape possible. What truly stood out was Andrew's dedication; he even returned for a complimentary follow-up inspection after the sellers addressed the issues he had identified.

"Greg was absolutely great----arrived early, incredibly professional, and found several things I suspect a lot of other competitors would have missed which were very much appreciated. The inspection went fast, but nothing was missed. This guy obviously knows his stuff, and we've already recommended him to a neighbor considering selling and buying a new house too. Again, great guy, highly professional and knowledgeable, and reasonably priced. A+++ Scott Hoffman"

Denver's #1 Home Inspection Service! Since 2001 HomeSpy Inspections is proud to provide the very best combination of detailed inspection, comprehensive education and customized inspection report – all presented with an exceptional house-side manner. We understand that purchasing a home can be very stressful and our goal is to listen, educate, and offer our expert opinion so that you can make an informed buying decision. Our calm and common sense approach puts things into perspective, rather than blows them out of proportion. We pride ourselves in our excellent communication and customer service skills. We have collectively saved our clients well over $1 million in negotiated items when purchasing their homes, as well as saving many clients from the huge mistake of buying a money pit! If we sound like a good fit for you, please give us a call. We look forward to helping you realize the dream of owning a new home!

"Matt provided the most educational and thorough inspection. This isn't my first purchase, but it is my first single family home, so one of the most important things to me from the inspection was to learn as much as I could about the house. Matt went above and beyond my expectations. He was happy to have me shadow him as he conducted the inspection - actually, he encourages this. He talked me through all of his major and minor concerns, pointed out things that had been done well vs. poorly, explained proper maintenance of many items, and addressed every single question I had (which were numerous). He even gave me advice on how to approach some projects that I was thinking about once I owned the place. One huge benefit for working with Matt is that he only books one inspection in a day. This means that he's not rushing to get through the inspection quickly, plus he's usually able to finish the report that afternoon/evening. I got my report the same day as my inspection (and it was thorough, he clearly put time into it). I highly recommend HomeSpy!"

"We had an amazing experience with Doug Fast through QBI. Doug conducted the inspection on our first home and was so through, detailed, and easy to understand when explaining the report. We received the report within a couple hours of it being completed and once again, it was very detailed yet easy to comprehend. I also really appreciated the inclusion of recommended handymen for each notation. If we had not moved forward with this house, we would have definitely used Doug for the next necessary inspection based on his work."

Radon Detection and Reduction questions, answered by experts

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

Through air sampling devices and surface swabs in key areas of concern.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

The short answer is no, air purifiers do not help with radon. While they certainly can improve the air quality of your home, they only clean pollutants from the air. Radon is radioactive, and it isn’t affected by the same filtration systems that handle other airborne particles, like dust and mold. The only thing that works is a radon mitigation system.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.
