"Marcos was friendly and fast, and flexible in scheduling. He and his crew did a great job for us in removing asbestos tiles from our basement flooring so we could have interior drain tiling installed. In the process, they also discovered some mold, which they were able to deal with at the same time. He came with a large crew, so they finished a large job very quickly. The space was well cleaned afterwards, and we received the necessary clearances. Highly recommend."

"Jon at Finest Home Inspection was great. He walked us through the inspection and his findings on site as well as answered our specific questions about the house. Our inspection report was provided the same day and the radon test results were provided as soon as they were available. He let us know what he wasn't able to check because there were tenants living in the house. He gave us his honest opinion on the house when we asked him. It can be difficult to assess the thoroughness of a home inspection, but now that we've been living in our home for a while, I am confident our home inspection was thorough. We haven't run into any issues that were not addressed in the home inspection. I would recommend Finest Home Inspection."

Radon Detection and Reduction questions, answered by experts

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.

Testing typically costs between $150 and $500, depending on the method used and the number of areas tested.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

Using an air purifier in your home or basement isn't an effective way to reduce or mitigate radon. Radon is an inert gas, meaning it doesn't react with other chemicals and can't be filtered the way particulates can be. While an air purifier can help improve your indoor air quality in other ways, don't rely on it to reduce radon.

You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional.
