Construction supervisor.

"Tom and April are indispensable if you are buying a home. Tom and April have inspected multiple homes for me, and their expertise is as good as it gets. As a first time home buyer, I did not know what to look for in some of the older homes in southeastern Connecticut, but Tom was able to explain everything clearly and concisely. He is a very thorough home inspector, and will methodically go through each room, outside of the house, and the basement to show any signs of wear or issues. If you use Sound Home Inspections, you can be sure that because of Tom's years in the field, and knowledge from flipping houses no stone will be unturned! He is an invaluable resource for any home buyer, and as I said, I have use him multiple times because I know that he will be honest and knowledge about about all aspects of a home inspection."

Radon Detection and Reduction questions, answered by experts

Costs depend on property size, test types, and additional services like mold sampling.

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

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. 

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

A DIY kit can lessen the sting that comes with paying for a professional assessment, but these comprehensive tests are true lifesavers. Inspectors are more likely to catch all of the pollutants and hazards in your air. Plus, you’ll still need a professional to verify and act on your DIY test results. 

Some kits don’t include tests for certain air pollutants or only detect their presence, but not their levels (i.e., mold spores). If you’re willing to shell out money for a DIY kit, it’s usually better to stretch your budget slightly higher for a more detailed assessment.
