I can’t recommend Nathan Johnson and JHS crawlspace specialist enough. We are currently doing a whole home remodel and our contractor was working on our sub flooring and found some issues under our home with moisture. He told me I needed to contact a crawlspace specialist immediately and get the issues corrected before they could proceed with their work. I contacted Nathan on a Tuesday. He came and gave me a quote on Wednesday. Worked all day long Thursday fixing the issues in a very difficult crawlspace, and had me totally finished by Friday. We did a full encapsulation of the crawlspace, he sprayed for any mold and fungi, replaced my crawl space door, and installed a permanent dehumidifier. Nathan is extremely easy to work with, very honest and fair. He takes a ton of pride in his work and it shows. If you have any crawlspace needs, do not hesitate to give this company a call. I promise you won’t regret it.
