Trusted Basement Waterproofing in Sussex County, NJ

25+ Years of Trusted Basement Waterproofing in New Jersey’s Highlands Regiony

Water In Your Basement Can Lead to Foundation Issues and Worse

United Waterproofing is proud to serve Sussex County homeowners with the most effective basement waterproofing systems in the region. 

Our patent-pending waterproofing process is designed to capture groundwater before it ever makes contact with your basement walls or floor, reducing moisture intrusion and eliminating interior water damage from the source.

Whether you’re situated along Lake Hopatcong or in the rolling hills of Sparta, we understand the unique drainage and foundation issues that come with living in Sussex County’s rural and mountainous terrain. 

Our sump pumps, backup systems, and interior drainage products are engineered to handle even the heaviest rainfall and snowmelt, so you never have to worry about a wet basement again.

Sussex County’s Soil & Elevation Make It Vulnerable to Basement Flooding

While Sussex County boasts some of the highest elevations in the state, the valleys and foothills in towns like Newton, Hopatcong, and Franklin often suffer from drainage issues, runoff flooding, and rapid groundwater accumulation. 

According to local flood maps, thousands of homes across Sussex County are at moderate to severe flood risk, particularly those along the Wallkill River and Papakating Creek.

Many homeowners think elevation protects them, but the combination of shallow bedrock, poor soil drainage, and historic homes with old foundations often leads to water seepage, structural damage, and mold. 

United Waterproofing’s interior system works beneath your basement floor to divert water away before it has the chance to enter, protecting your foundation and everything stored inside.

A Better Waterproofing Solution for Northern NJ Homes

From the colonial-era charm of Newton, the county seat founded in 1751, to the lakeside homes of Hopatcong, once a summer resort destination for wealthy New Yorkers, Sussex County is steeped in rich history—and so are its homes. 

Many of these properties were built long before modern drainage codes, making them especially vulnerable to water intrusion, foundation cracking, and moisture buildup.

Sussex County’s unique topography—rolling hills, shallow bedrock, and glacial soil—only increases the risk. Homes built into slopes or near wetlands like those surrounding the Wallkill River National Wildlife Refuge often struggle with runoff, groundwater seepage, and seasonal flooding. 

Even newer builds aren’t immune to the challenges posed by the region’s heavy snowfalls and nor’easters.

At United Waterproofing, we don’t apply surface-level fixes or install outdated sump systems that fail when you need them most. Instead, we’ve developed a patent-pending waterproofing solution tailored for Sussex County’s diverse and historic housing stock. 

Our system captures water at its entry point, beneath your basement floor and along the foundation perimeter, then channels it away using high-performance, perforated piping and top-tier sump pumps designed for longevity, freezing resistance, and heavy-duty use.

Whether your home rests along the slopes of High Point State Park, the banks of Lake Mohawk, or in the preserved farmlands near Augusta, you deserve a waterproofing system engineered to endure the region’s harshest conditions.

Don’t wait for the next heavy downpour or spring thaw to reveal costly damage. Protect your home, history, and peace of mind now with United Waterproofing.
