Called DJM Spray Foam Inc., within a day or two, Jesse called and set up a time the following day to come and look at my crawlspace to provide a quote. DJM was the first company that suggested laying a plastic vapor barrier over the entire crawlspace floor and then sealing all the edges with the spray foam, including all the load bearing columns. Once I approved the quote, they were here within a week, finished up in a few hours, and did a great job at a great price. I would recommend DJM Spray Foam Inc to anyone who asks!
