Comment: We invested in a French Drain , wall refinishing, crawlspace encapsulation and a dehumidifier with Jamison Basement Waterproofing and now it was time for the annual maintenance 1year from the installation date and Jamison even sent out the crew Foremen Steve who originally installed our waterproofing system to do the service on our system . Steve was on time and explained and answered all our questions plus tested and inspected our entire system . Thanks Jamison !
