First the service team that redid my crawl space. Threw away the box to my dehumidifier, so I could not register for my 5-year warranty. I own an older home and the vinyl in the home has been down for several years. During the sales call the representative failed to tell me that we would pay them a ton to redo our crawl space. And the dehumidifier would dry out all the wood and keep the mold gone but in doing so buckled all three of my bedroom floors and now the vinyl has humps in it, and I am going to be out a thousand of dollars now to replace the vinyl or put the carpet down. I have called a few times only to be told someone will call me back and no one has. So I am putting this out there don't use them to redo a crawl space in an old home, or you will be out putting flooring in your home.
