"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."

Buying property is one of the most important decisions you’ll ever make. Before you sign on the dotted line, be sure your investment is a good one. The professional building inspectors at LESA Inspections can provide you with the assurances you need to move forward in your real estate transaction with confidence.

"Do not work with LESA. I am the first to write a positive review and try my best to avoid negative, but LESA's negligence has cost my family $26,000 in unexpected repairs after our home purchase. Choose a different inspector. First, our entire basement ceiling/floor system was contaminated with a light fluffy mold. It was discovered by another specialist after our home purchase. My husband remembers asking Simao what it was during the inspection, and he said the basement was so dry it must be dust. The remediation cost us $16,000. Today, we had an HVAC company come out to service our boiler. Simao had told us during the inspection that it was old, however we could expect to get at least 1-2 years out of it. Our HVAC company immediately told us our unit is not even safe to use and needs to be completely replaced. This will cost us at least $10,000. After purchasing a home, these types of surprises are the last thing you need. Do yourself a favor and go elsewhere - please."

Radon Detection and Reduction questions, answered by experts

Radon is a colorless, odorless gas that can cause lung cancer; testing ensures safe indoor air quality.

It is possible to test for radon yourself using DIY radon test kits, but these at-home test kits should never be a replacement for professional radon testing. DIY test kits can provide some information about radon exposure in your house, but your indoor temperature and humidity can affect the results, as can improper usage of the test kit. You could save yourself some money by hiring a radon professional to begin with, and when it comes to your family’s safety, hiring an experienced professional to do the testing is usually the best option.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

Yes, DIY kits are available, but professional testing provides more accurate results and comprehensive reports.

No level of radon is technically safe, but because it’s everywhere—even in the air outside—it’s impossible to avoid entirely. Instead, the Environmental Protection Agency encourages taking preventative measures if the levels of radon in your home rise above 2 pCi/L. (For reference, the average radon level in homes across the United States is 1.3 pCi/L.
