I just wanted to take the time to thank you for all your help regarding the decision to clean up my crawl space. The results are amazing. The crawl space looks, and smells great. The air is fresh and humidity is gone. After reading the Book "CrawlSpace Science" , we came away with information you never even think about. The dehumidifier and sump pump are working fine. As a customer, I am very satisfied that all my questions were answered in a timely manner, and my requests regarding unforeseen issues were granted without question. I will gladly recommend Ayers Basement Systems to all potential customers. Other residents on the bay will be told about this system. Our home in Northern Michigan means a lot to my wife and myself. The potential damage to the foundation could have been very costly.
