Job Stories From Great Neck, NY
Leaking Foundation in Great Neck, NY

A homeowner in Great Neck, New York had a basement foundation that was allowing water to enter the basement, this was causing the homeowner to not use parts of their basement with the fear the basement might flood in that area. The homeowner was tired of living with a flooding basement and gave us a call to come inspect their basement issue, after sending one of our specialists out to inspect the basement they recommended they waterproof their basement if they wanted to stop the basement from flooding. The way we waterproof basements is by our crew coming in and jackhammering out a trench around the perimeter of the basement so they can install our WaterGuard system. The way our WaterGuard system works is by it being installed in the trench we dugout and connected to our sump pump system so that as water tries to make its way into the basement it gets captured by our WaterGuard system that then directs the water into our sump pump system, which will then discharge any water out and away from the foundation of the home. To ensure this basement remains completely dry and healthy we installed our dehumidifier system in the basement, which will filter out any mold, mildew, or moisture from the air helping to improve the overall air quality in this basement. Now this homeowner has a basement that will remain dry and usable for many years to come. 


This homeowner in Great Neck, New York had an old sump pump system in their basement which wasn't keeping their basement dry. A sump pump system is the heart of any basement waterproofing system and if that stops working your basement will begin to flood again. This homeowner noticed some small flooding in their basement and decided to was time for a new sump pump system and gave us a call.  Our crew came in and replaced this homeowner's old sump pump system with our basement waterproofing system, which consisted of our WaterGuard and TripleSafe sump pump system. Our crew first installed our perimeter drainage system called WaterGuard, which is designed to capture and water before it enters your basement and redirects the water to our TripleSafe sump pump system. The TripleSafe Sump Pump system comes with three separate pumps in it which ensures your basement remains completely dry, all the time even in a power outage. Our sump pump comes equipped with a primary pump which is designed to handle large amounts of water even in the worst weather conditions. Our secondary pump will kick on if the primary ever failed or if the primary pump is being overwhelmed with water. The final pump in our sump pump system gets connected to our battery backup system, meaning that if the home ever lost power this pump would kick on keeping the basement completely dry and usable. The battery backup system is a great feature to have because you never know when you will be without power. Now this homeowner a brand new basement waterproofing system that will keep their basement completely dry and usable even during a power outage.
