Warren County homes face some of the harshest weather conditions in New Jersey, from frigid winters to blazing summers, heavy rain, snowmelt, and rising water tables. It’s no surprise that basements in the area need extra protection against the harsh elements.
At Basement Waterproofing Specialists, we’ve been helping Warren County homeowners stay dry for four generations. As a woman-owned, local, family business, we truly understand the impact that North Jersey’s extreme weather has on your home. From heavy rains to spring snowmelt, and high groundwater levels, these elements create constant hydrostatic pressure against your foundation. Over time, this pressure can lead to basement leaks, musty odors, mold growth, and even structural damage—putting your home’s integrity at risk.
What We Do in Warren County
Custom waterproofing solutions tailored specifically for the challenges homes face in Warren County:
Interior & exterior basement waterproofing systems that stop water from entering through all possible entry points, ensuring a dry, healthy basement.
Sump pump installation, with battery backups and alarm systems, to keep water at bay even during power outages. This ensures your basement stays dry no matter what.
French drains, yard drainage systems, and grading fixes that direct water away from your home’s foundation and prevent soil erosion, a common problem in this area.
Crawl space encapsulation & vapor barriers, designed to block moisture and improve air quality in your home—helping to prevent mold growth and maintain healthier indoor air.
Foundation crack repair & stabilization, to seal and support your foundation, ensuring cracks don’t grow over time and lead to more serious issues.
Dehumidification & mold prevention, ensuring your home remains dry, free of moisture, and protected against dangerous mold that can affect your health.
We start every project with a free inspection to identify potential problem areas, such as wall/floor cove joints, foundation cracks, window wells, or stairwells. Once we’ve assessed the situation, we design a custom waterproofing solution specifically tailored to the unique foundation and soil conditions of your home.
