Customers say: True professional
"Jeremy was very professional and did a great job. He had reached out after I scheduled the original appointment to reschedule due to poor weather conditions. He offered to move the appointment to a date/time that he usually doesn t work to accomodate my needs. Once he had finished his work, he walked my fiance and I through everything explained it all very clearly. He also thoroughly explained the process for testing radon levels and getting test results back after the mitigation installation was complete. Would definitely recommend his services as he did a great job and his quote was very competitive."

"Great, they did the inspection in a timely manner & provided the report in a timely manner. The only problem was that there was no follow up or estimate for installing a radon mitigation system. We really wanted to know the cost of installation & if it was required."

"They did a great job with the installation and made sure the Radon was under the level it needed to be. He had to make a couple of trips to make that happen but was very polite and profession through the whole process."

"In both spoken and written communication, this company was extremely professional. In the end they were a few thousand dollars higher in their estimate than the company I went with. If not for that I would have gone with EJS and I wouldn't hesitate to mention them to friends and family. I wanted to give them a good review here simply due to the level of courtesy, promptness, and professionalism they displayed.
