Before and After Pictures from Brooklyn
Waterproof Basement Walls in Brooklyn, NY

This Brooklyn basement had water seeping in where the walls met the floors. Quailty 1st Basement Team Systems installed WaterGuard, a SuperSump sump pump, and Everlast wall paneling. The WaterGuard drainage channel will lead any incoming water to the SuperSump sump pump, which will then safely deposit the water outside of the basement. Everlast wall paneling restored the lower half of this basement wall, giving it a fresh new facelift. Everlast not only looks great, it is mold resistent and has a waterproof PVC coating that will keep it dry and moisture free. Now this Brooklyn basement will stay dry and clean!

This homeowner needed extra support in their crawl space after they noticed stair step cracks. They noticed the floor above the crawl space was no longer level which indicated that their wooden beams underneath were sagging. Our Foundation Foreman, Victor and his crew installed 9 SmartJacks across the crawl space beams to provide additional support and stabilization.

We need investigation and waterproofing at ground floor by our back patio.
Vicinity of Mill Avenue in Brooklyn
My basement floods when it rains. problem #1 is that the deck door railing collects water on the main floor which then seeps into the basement. So we installed plexiglass on the screen doors to keep.the rain out. Problem #2 is that there is a "fake drain" which doesn't appear to connect to any pipes right front of the basement exit door. today I realized that it was filled up with dirt but not before my basement flooded. Hope you can provide a free estimate.
