Job Stories From Shelter Island, NY
Basement Waterproofing Contractor in Shelter Island, NY

A homeowner in Shelter Island, New York had a basement that was flooding whenever it would rain a lot outside and the homeowner wanted a perimeter solution to their basement issue, so they gave us a call to come inspect their basement issue. After sending one of our specialists out to inspect their basement issue they recommended that the homeowner have their basement waterproofed using our WaterGuard, Triplesafe sump pump systems, and our SaniDry dehumidifier. The way our basement waterproofing system works is by our crew coming in and installing our WaterGuard system around the perimeter of the basement. WaterGuard works by capturing any water that tries to enter the basement through the wall and floor joints, which creates a channel around the basement and directs any water into our TripleSafe sump pump system. As water enters our TripleSafe sump pump system it collects and discharges any water that enters it with the help of one of the three pumps, that are installed inside the sump pump system. The first pump in our sump pump system is our primary pump, which will handle most of the water that enters the system. In the event the primary pump becomes overwhelmed with water or fails, the secondary pump will kick on and continue to remove water. With the TripleSafe sump pump, you never need to worry about your basement flooding because your home lost power. Our third pump in our system gets connected to our battery backup pump, which will kick on if the home ever lost power and allow the system to continue to run. The final thing our team installed to ensure this basement remains completely dry all the time is our SaniDry dehumidifier which will filter moisture out of the air, which will help prevent mold or mildew from growing in addition to improving the air quality in the basement, by filtering out small mold and dust particles that might be in the air. Now this homeowner has a basement that’s clean, dry, and usable.

This homeowner in Shelter Island, NY had a living room whose floors were sagging down into the crawl space making the living room floor uneven, the homeowner gave us a call to see if we could make their floor level again. We were able to make this homeowner's floor level again by installing our SmartJack system in the crawl space which is designed to give the floor the proper support it needs while also being able to raise the floor and make it level again with the rest of the living room floor. Now this homeowner has a living room that is level and no longer sagging down into the crawl space.

Over the last two years, the humidity in the basement has increased, and a new settling crack on the basement floor appeared . i think there is not enough drainage away from the basement.
Project Location: Shelter Island, NY
Recently we've been battling some hydrostatic water pressure from the last few major rain storms(for example our NYE bath). From what I can see it looks like the previous owners installed a French drain system but it only runs 3 of the 4 walls, and along 2 of the wall there is water so the system must be failing in some way.
