5 stars!
Evergreen did everything they said they would and more. I actually don't mind going into the basement now since they sealed it. The air quality in the house is noticeably better and it's warmer in the winter. We can even store clothing down there where before, whatever was in there would mildew. Even the spider population declined! I used to vacuum so many of them from the corners of the ceilings in the house. Not any more!
The Evergreen staff impressed us with their knowledge and were responsive to any questions or requests we had throughout the whole project. Their follow-up was great.
Chris and I would highly recommend Evergreen Home Performance and Brian Robinson in particular!
