From musty smells to standing water, basement moisture issues are common in Newark homes, but they don’t have to be permanent. At '58 Foundations & Waterproofing, we design basement waterproofing systems that stop water at the source.
Between humid summers, aging drainage systems, and clay-heavy soil, basements in Newark are no strangers to water problems. Whether you're near White Clay Creek or tucked into one of the city’s older neighborhoods, the combination of moisture and soil pressure can lead to water stains, musty odors, or full-scale basement flooding.
At '58 Foundations & Waterproofing, we help Newark homeowners stop water at the source. Our basement waterproofing systems are designed specifically for Delaware’s climate and soil conditions, so whether you're dealing with seepage, high humidity, or standing water, we can restore your basement and protect what matters above it.
Basement water issues in Newark are usually the result of one key factor: pressure. The clay-rich soil in this part of Delaware absorbs moisture quickly and drains it slowly. After storms or snowmelt, that water builds up around the foundation and pushes against the basement walls with force. Over time, it finds a way in, through cracks, joints, or porous concrete.
Many homes in Newark, especially those built before modern building codes, lack interior drain systems or rely on aging exterior waterproofing that has broken down over time. Some have basements with poor grading, old window wells, or downspouts that drain too close to the home.
When moisture starts to enter, it doesn’t just stay in the basement. It raises humidity levels throughout the house, encourages mold growth, and slowly breaks down materials behind walls and under floors.
Without proper waterproofing, these issues don’t stop with one rainstorm; they get worse with every season.
In Newark, basement water problems often start with small signs that are easy to overlook until they spread. If you're noticing any of the following issues, your home may already be at risk for long-term moisture damage.
Musty or earthy smells
That damp, stale smell rising from the basement is one of the earliest signs of water intrusion. Even if you don’t see puddles, moisture may be entering through the walls or floor slab, fueling mold growth and mildew beneath the surface.
Water stains or discoloration on walls and floors
White, powdery residue or brown streaks on your basement walls could be efflorescence, a mineral deposit left behind when water evaporates through concrete. It’s a clear sign of moisture migration and increasing pressure on the foundation.
Cracks in the foundation
Hairline cracks can be harmless, but wider cracks, especially those that leak or run horizontally, often point to structural stress from water buildup outside the foundation walls. Newark’s freeze-thaw cycles and slow-draining soils make this especially common.
Pooled water or damp spots after rain
If water collects in certain areas after a storm, your basement may lack an internal drainage system or have poor exterior grading. This puts your home at constant risk for flooding or long-term rot.
Mold or mildew growth
Visible mold on walls, baseboards, or behind stored items means there’s sustained moisture in the space. Mold spreads quickly and affects not only materials, but also your indoor air quality.
High indoor humidity or window condensation
When moisture rises from the basement into your living spaces, it can overwhelm your HVAC system and raise humidity throughout the home. You may notice fogging windows, clammy air, or worsening allergy symptoms.
Increased energy bills
Damp basements make it harder to regulate temperature. Your heating and cooling systems have to work harder to keep the rest of the house comfortable, especially in Newark’s humid summers and cold winters.
At '58 Foundations & Waterproofing, we build every waterproofing system to match the home, not just the symptoms. Newark’s combination of old construction, sloped terrain, and clay soil demands solutions that work beneath the surface and hold up over time.
Here’s how our basement waterproofing company helps Newark homeowners protect their homes from the ground up:
Interior Drain Tile Systems
We install perimeter drain systems beneath the basement floor to collect and redirect groundwater before it rises. These systems relieve pressure from outside and stop water from reaching the interior.
Sump Pump Installation
A sump pump is the heart of any drain tile system. Installed in a sealed basin, it removes collected water and pushes it safely away from the home. We also offer battery backup systems for power outages during storms.
Foundation Crack Repair
Leaking or widening cracks are sealed using professional-grade materials like polyurethane injection or epoxy. These repairs stop seepage and reinforce the wall structure.
Wall Vapor Barriers
To prevent moisture from evaporating through concrete walls, we install heavy-duty vapor barriers that protect finished or unfinished basement spaces from humidity and mold.
Dehumidifier Installation
We offer high-performance basement dehumidifiers to keep humidity levels safe year-round. This is especially helpful in Newark, where humid summers and heavy rain create persistent damp conditions.
Every system we install is backed by our Life-of-the-Structure Warranty, so you can count on it to perform for the long term.

In Newark, where clay-heavy soil holds water and summer storms arrive fast, a sump pump system isn’t just a safeguard; it’s essential. Even homes with proper grading and modern drainage can flood if there’s no system in place to remove water once it reaches the foundation.
A sump pump works quietly in the background, moving water out before it rises into your basement. It doesn’t just protect your space; it supports your entire waterproofing system and provides peace of mind every time it rains.
A sump pump system collects and removes groundwater from beneath your basement floor before it has a chance to flood the space. Installed as part of an interior drain tile system, it operates automatically and requires minimal upkeep.
A complete sump system includes:
Many homes in Newark, especially those near creeks or in low-lying neighborhoods, experience water pressure around the foundation during every major rainstorm. Without a sump pump, that pressure builds until it forces water inside.
Installing a sump system offers:
From neighborhoods near the University of Delaware to wooded lots outside the city center, Newark homeowners rely on sump pumps not just to remove water, but to prevent disaster before it starts.
Basement waterproofing costs in Newark depend on the type of water problem you're facing and how far it has progressed. For some homes, a simple drain tile and sump pump system may be enough. Others may need crack repairs, vapor barriers, or humidity control to fully protect the space.
