We own a home in Seattle and called Environix to come in and test the air quality throughout our house (and check ceiling for asbestos). Our main concerns were mold but we have some health issues in the family and wanted everything checked out. I talked to Kathy and she gave me a lot of information and some suggestions and very good at explaining what we would be getting for the cost. I received an email from her before the visit that was very helpful. The person doing the testing was Dan and he came exactly when he was suppose to. He spent over an hour checking out our house. He let me follow him every step of the way explaining every thing he saw and was looking at. I had endless questions and I felt that he was very patient with me. Dan explored every nook and cranny of the house, attic, basement and even went out on the roof to look at some peeling siding. The report that we received was very comprehensive. Dan called and explained everything gave recommendations and offered to help us with assessing HVAC contractors. I felt the information that we were given was complete and worth the cost. Honestly, I cannot say enough about Environix except for I wished we called them two years ago when we bought the house. If you are having any concerns or you feel like maybe your house is making you sick do yourself a favor and call them.
