"Work was done promptly and the crew was friendly and thorough. They installed a cap over the floor drain that prevents air from infiltrating from the foundation drainage system while still allowing any water from the basement to escape should the washer overflow or a pipe break, etc. As a result (and side benefit) my basement is less humid and no longer has that occasional musty smell.
Six months later and everything is working fine. A retest for Radon showed virtually no presence whereas, before, tests showed a rather high concentration.

"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.
