When we first visited this home it was experiencing structural and mold issues because of poor drainage around the home which allowed water to get into the crawl space. The homeowners contracted with us to come in and remediate the mold, fix the rotten wood, install a drainage system and moisture barrier. We strongly encouraged them to get a dehumidifier installed by the end of winter (which they did not). Once we came back a year later to maintenance our sump pump and do a crawl space inspection we noticed they had more structural damage and mold had came back. this was all due to not getting a dehumidifier installed as we originally advised them. This is just one of many exampled why we recommend dehumidifiers. Unfortunately this homeowner had to pay about $5,000 more than what they originally would have. Give us a call if you are looking to get your crawl space issues taken care of!
