Before water can seep into your foundation, it is pushed away by the french drains. They’re crucial to long-term flood prevention and basement protection.
A sump pump goes to town when water builds up below your home. It quickly removes it before any damage is caused. When in a storm, it’s your basement’s best friend.
We seal cracks, stop leaks, and prevent costly water and mold damage by using interior and exterior waterproofing methods.
Grated drains redirect surface water, which reduces pressure against your foundation. A big help in preventing flooding and basement seepage, especially in heavy rain.
In a rainy area like Nassau County, this waterproof barrier that is applied directly on the outside of your home, is a great long-term solution. It will make sure water is unable to get into the basement.
To prevent rainwater from pooling near your basement, we can grade your foundation so the ground slopes away from your home.
Designed to keep water from collecting near basement windows, these window well systems are key to stopping leaks and water damage where it starts.
