              The office staff was courteous and made an appt. rather quickly. Richard Alexander came to my house and I was very impressed. The presentation was great and the video answered all the questions. I believed in the science behind the product. I was able to schedule the work to be done within 1 week. Deon and his crew arrived on time and had the job finished within 1 day. They were very professional and cleaned up leaving no mess behind.

    Customer Testimonial

              After Hurrican Sandy left us with a flooded crawlspace and 1 foot of water on the first floor of our house, we called Healthy Basement Systems. They came and did their magic. Before hiring Healthy Basement Systems, our crawlspace would always have standing water after a rainstorm. The house would get all musty and humid. There was always condensation on the windows. I suffered with allergies. Since having our crawlspace serviced, the house is perfect! No more water and no more allergies. Another plus is that the crawlspace is now usable storage space. One of the best things we have done to our home!

    Customer Testimonial

              Donna C. lives in Long Island, and as it happens to many homes in that area, her home's basement was very humid and unhealthy. After inspecting the property, Bill Simone's Healthy Basement Systems recommended and installed the powerful SaniDry dehumidifier. "They recommended that I buy a dehumidifier which has been a life saver," says Donna. "I am so happy with it!"
