Jim and Karen are very knowledgable and great to work with. They went above and beyond and I highly recommend them. The mold treatment has made a huge difference in the air quality in my house. I no longer have that musty smell when I return after a long trip. I had previous mold treatment that involved cutting out portions of molded dry wall and removing baseboards, but didn't get to the mold that was throughout the house. This treatment deals will the whole house and my health has improved since it. I can't recommend it strongly enough for anyone with an old, musty smelling house.
