Our customer purchased this house with the intent to renovate and resell. While the house was on the market, many of our customer's potential buyers noticed the severe leakage and water table issues within the basement/crawl space leading them to seek other homes. As the #1 Waterproofer on Long Island, our customer requested us to develop a system that would create a safe and healthy environment for this basement/crawl space. Our experienced systems design specialist Michael Alexander initially recommended a full perimeter waterproofing system, however he and Bill Simone collaborated with our customer to create a custom solution for the water seepage. 


After deciding on a CleanSpace vapor barrier encapsulation led by foreman Larry Foster, this system was able to drain the existing leaks and stop the water vapor from continuing to permeate through walls. Furthermore, a sump pump was installed to efficiently pump out the water through the discharge line. The efforts made by Healthy Basement Systems helped sell this house while also creating a safe and healthy environment for our customer and future home owners.

Job Stories From Sayville, NY
Basement Finishing in Sayville, NY

After having this basement waterproofed by our team many years ago, this homeowner in Sayville, NY decided they wanted to convert their basement into a usable living space, so they gave us a call. Our team was able to bring this homeowner's dream basement to life by installing our Everlast Basement Wall Paneling System with decorative white trim along the top, Thermal Dry Flooring, Ceiling Tiles, and Doors. Our team also installed some baseboard heating to help keep the basement warm during the colder months. We also installed our SaniDry Dehumidifier in the utility closet we created for them and ducted the dehumidifier so that it can still filter out the air in the basement while hiding it away in a utility room.  Since having a basement exit is a must on Long Island we installed an Egress Window in the event there is an emergency, the family has a safe exit to exit from. Now this homeowner has a basement that is beautifully finished for the entire family to enjoy for many years to come!
