Basement waterproofing in Bellmore isn’t about guesswork – it’s about using the right techniques in the right places. Our team takes a targeted approach, blending both interior and exterior solutions to tackle moisture at the source. Whether it’s heavy rain or rising groundwater, our systems are designed to keep basements dry, clean, and always reliable through any season.
French drains are engineered to catch and redirect groundwater before it reaches your basement. When strategically installed around your foundation, french drains provide a first line of defense and keep your space dry beneath the surface.
When water accumulates beneath your home, the sump pump kicks in and automatically removes it before any damage occurs. Installing a sump pump system is a simple but smart way to stop flooding during storms or rapid snowmelt.
Cracks in basement walls or floors can let water in and, over time, invite mold. Our foundation crack repairs aren’t just a quick fix, the problematic areas get permanently sealed to prevent future leaks and restore your foundation’s strength.
These surface-level drains collect water before it reaches your basement walls. Driveways, patios, and entryways are common places to install grated channel drains. Doing so helps reduce pressure against your foundation by redirecting excess water away from your home.
This waterproof barrier, that acts as a protective layer, is applied directly to the exterior of your foundation, making sure water is unable to get into your basement. It’s a long-term solution, especially useful in parts of Nassau County that has plenty of rain.
Water can pool near the foundation if there is poor drainage around your home. We grade your foundation to improve water flow, which keeps moisture away from your basement and reduces the risk of erosion.
Without proper drainage, water can pile up in window wells and seep through basement windows. We install window well drainage systems that channel water away, helping to keep your home dry during heavy downpours.
