"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

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

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. 

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.

Short-term tests take 2-7 days, while long-term monitoring may require up to 90 days for accurate results.

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.

Results from radon testing usually take a week to process after the test period ends, with expedited services sometimes available for urgent cases.
