How We Fix It For Good
For waterproofing and flood prevention in Franklin Square, we use proven techniques that deliver real results. Whether we’re sealing from the inside or defending from the outside, our methods are aimed directly at the root of the problem.
The result? A dry, healthy, and structurally sound basement. One less thing for you to worry about.
French Drain System
French drains reroute water away from your foundation before it can seep in. They’re key to long-term flood prevention and basement protection.
Sump Pump Installation
As soon as water shows up, a sump pump goes to town – quickly removing it before it causes any damage. It’s your basement’s best friend in a storm.
Basement Crack Fix in Franklin Square
Using both interior and exterior waterproofing, we seal cracks, stop leaks, and prevent costly future damage from water and mold.
Grated Channel Drains
Grated drains redirects surface water – a major help in preventing flooding and basement seepage, especially in heavy rain.
Exterior Membrane Support
This waterproof membrane wrap gives your foundation a hug from the outside, creating a strong barrier that blocks water from ever getting in.
Foundation Grading
We make sure the ground slopes away from your home with foundation grading, so rainwater doesn’t have a chance to pool near your basement.
Window Well Drainage
Designed to keep water from collecting near basement windows, these window well systems are key to stopping leaks and water damage where it starts.
