From city homes in Wilmington to historic properties in Old New Castle and family neighborhoods throughout Newark, basements in this part of Delaware face serious moisture challenges.

Whether you're seeing signs of dampness, standing water, or musty odors, our team delivers long-term protection to keep your home safe and dry.
Basement water issues in New Castle County often start with the soil. Much of the area, especially in places like Bear, Glasgow, and Elsmere, sits on clay-rich ground that expands when wet and contracts when dry. This constant shifting places pressure on basement walls and creates cracks where water can seep through.
Older neighborhoods in Wilmington and New Castle City frequently experience water problems due to aging foundations and outdated drainage systems. Many of these homes were built before modern waterproofing practices were common, leaving them vulnerable to groundwater intrusion during heavy storms.
The flat terrain throughout the county also contributes to poor surface drainage. Without proper grading or functioning downspouts, rainwater tends to collect around the foundation instead of draining away. Over time, this moisture builds up around the structure and pushes its way inside.
These local conditions are why so many homeowners search for a reliable basement waterproofing contractor in New Castle County, someone who understands how the soil, weather, and housing stock all play a role in long-term water intrusion.
Basement water problems often begin quietly. What starts as a damp corner or faint odor can quickly escalate into structural damage, mold growth, or ruined belongings. In New Castle County, where many homes were built decades ago and drainage systems vary by neighborhood, early detection is key. Here are the most common signs to watch for:
If you’re seeing any of these warning signs in your New Castle County home, basement waterproofing can help prevent long-term damage and restore a safer, healthier environment.

In New Castle County, sump pumps aren’t just helpful—they’re essential. With high groundwater levels, compacted clay soils, and neighborhoods built on relatively flat terrain, water often has nowhere to go during a storm. That’s why even a light rain can lead to water collecting around the foundation and pressing its way into the basement.
Areas near the Christina River, the Brandywine Creek, and flood-prone zones around Edgemoor, Newport, and Wilmington’s riverfront are especially vulnerable. But even homes in suburban neighborhoods like Glasgow or Bear can experience seepage if the grading is poor or the drainage systems are outdated.
A professionally installed sump pump works in tandem with your interior drainage system to move water out of the basement before it becomes a problem. When rising groundwater reaches a certain level in the sump basin, the pump activates automatically, pushing water safely away from the home.
Our Workhorse Sump Pump System is built for reliability under pressure, delivering consistent performance during extended storms. For added security, the Workhorse OT battery backup keeps your system running even if the power goes out, giving homeowners peace of mind during the kind of unpredictable weather New Castle County often sees in late summer and early spring.
Without a dependable sump pump, your entire waterproofing system is left vulnerable. That’s why we treat sump pump installation as a critical component of every comprehensive basement solution.
Basement waterproofing costs can vary depending on the size of the basement, the severity of the moisture problem, and which solutions are needed to fix it. In New Castle County, older homes with outdated drainage or foundation wear may require more involved repairs than newer construction.
