Basement waterproofing in Seaford isn’t guesswork, it’s about applying the right techniques where they’re actually needed. Our team takes a direct approach, combining interior and exterior basement waterproofing solutions that stop moisture at the source. Anything from steady rain or rising groundwater, our systems are built to keep your basement clean, dry, and dependable throughout all the seasons.
French drains are designed to capture and redirect groundwater before it gets a chance to reach your basement. Installing french drains strategically around your foundation offer a first line of defense that keeps your space dry beneath the surface.
When water builds up below your home, sump pumps get to work, automatically removing it before it causes trouble. Installing a sump pump system is a simple but powerful way to stop flooding during storms or rapid snowmelt.
Cracks in basement walls or floors can let in water and invite mold over time. Our foundation crack repairs aren’t just a quick patch, they permanently seal problem areas to prevent future leaks and restore your foundation’s strength.
These surface-level drains collect water before it can reach your basement walls. Common places to install grated channel drains are in driveways, patios, or entryways. This helps reduce pressure against your foundation by redirecting excess water away from your home.
This waterproof barrier is applied directly to the outside of your foundation, making sure that water won’t be able to get into our basement. It’s a long-term solution, especially useful in parts of Nassau County that has lots of rain.
Poor drainage around your home can cause water to pool near the foundation. We grade your foundation to improve water flow, keeping moisture away from your basement and reducing erosion risks.
Without proper drainage, water can collect in window wells and leak through basement windows. We install window well drainage systems that carry that water away, helping you keep your home dry even during heavy downpours.
