You stop worrying every time it rains. No more towels on the floor, no more musty smell creeping upstairs, no more wondering if that crack is getting worse.
A dry basement means you can use the space again. Store things without ruining them. Finish it if you want. Sell your home without explaining away water stains or that “basement smell.”
It also means your foundation isn’t slowly failing under hydrostatic pressure. New Hanover’s clay-heavy soil doesn’t drain well, so water builds up fast and pushes hard against your walls. Left alone, that pressure creates cracks, shifts walls, and turns small problems into expensive ones. Waterproofing stops that cycle before it costs you more than it should.
We’re a family-owned residential waterproofing company based in Plymouth Meeting, serving Montgomery County and surrounding areas including New Hanover. We’ve spent over 15 years working in basements just like yours, dealing with the same soil, the same weather, the same problems.
New Hanover gets about 40 inches of rain a year, and your soil holds onto it. That’s why so many basements here flood after spring thaw or heavy storms. We know what works in this area because we’ve done it hundreds of times.
We’re not the cheapest option, and we’re upfront about that. But we back every job with a lifetime transferable warranty, and we don’t cut corners to win bids. You’re hiring people who treat your foundation like it’s our own.
First, we come out and look at your basement. Not a sales pitch—an actual inspection. We check for cracks, measure moisture levels, look at grading outside, and figure out where the water’s coming from.
Then we explain what’s happening and what it’ll take to fix it. If it’s a simple crack repair, we’ll tell you. If you need a full interior drainage system and sump pump, we’ll walk you through why and what that looks like. No upselling, no scare tactics.
Once you’re ready to move forward, we schedule the work. Most jobs take one to three days depending on the scope. We install interior drainage systems that relieve pressure under your floor, seal cracks with methods that last, and set up sump pumps with battery or hydro-powered backups so you’re covered even when the power goes out.
You can stay in your house while we work. It’s not silent, but it’s not a full renovation either. When we’re done, we clean up, test everything, and walk you through how the system works. Then we warranty it for life.

Our waterproofing systems are built for New Hanover’s conditions. That means interior drainage designed to handle high water tables and clay soil that doesn’t let water pass through easily. We install sub-floor pressure relief systems that outlast old-style French drains and don’t clog with sediment over time.
Sump pumps get installed with backup power—either battery or our hydro-powered siphon system that runs off your water line. Both keep your basement dry even during storms that knock out electricity. We also handle foundation crack repair using methods that flex with your home instead of cracking again in six months.
If you’ve got mold or moisture damage, we address that too. Waterproofing won’t fix mold that’s already there, but it stops new growth by controlling humidity and eliminating the water source. Keeping your basement dry improves air quality throughout your home, which matters if anyone in your family deals with asthma or allergies.
Every system comes with our lifetime transferable warranty. If you sell, it transfers to the next owner. That’s not standard in this industry, but it should be.
Most basement waterproofing projects in New Hanover run between $4,000 and $8,000, but the range is wide—anywhere from $600 for a simple crack repair to $14,000 for a full perimeter system with exterior work. It depends on your basement size, how much water you’re dealing with, and what’s causing it.
If you just need a sump pump installed, that’s on the lower end. If you need interior drainage around the whole basement, crack sealing, a sump system with backup, and mold remediation, it adds up. We don’t give ballpark prices over the phone because every basement is different, but we do free inspections and clear estimates before any work starts.
The cost also reflects the warranty and the quality of materials. Cheaper jobs often mean cheaper systems that fail in a few years. We use components designed to last decades, and we back them with a lifetime warranty. You’re paying for a fix that actually holds up.
New Hanover’s soil is clay-heavy, and clay doesn’t drain well. When it rains hard or snow melts fast, that water has nowhere to go, so it pools around your foundation and pushes against your basement walls. That’s called hydrostatic pressure, and it’s strong enough to force water through cracks, seams, and even solid concrete.
If your gutters dump water right next to your foundation, or if your yard slopes toward your house, you’re making it worse. But even with perfect grading, clay soil holds water long enough to cause problems. That’s why so many basements here flood in spring or during summer storms.
The fix isn’t just patching cracks. You need a system that relieves pressure and gives water a path out before it gets inside. That usually means interior drainage and a sump pump. Exterior waterproofing helps too, but it’s more invasive and expensive. Most homes here do fine with a good interior system.
A properly installed interior drainage system can last 20 to 30 years or more without major maintenance. Sump pumps typically last 7 to 10 years depending on how often they run, but they’re easy to replace when the time comes. The drainage itself—if it’s done right—shouldn’t need replacing in your lifetime.
That’s why the quality of installation matters. Cheap systems clog with silt, shift out of place, or fail because they weren’t sized correctly for the water volume. We design systems based on your specific conditions, not a one-size-fits-all template.
Our lifetime warranty covers the system for as long as you own the home, and it transfers if you sell. If something fails because of how we installed it, we come back and fix it. That’s not common in this industry, but it should be. You’re making a big investment, and it should last.
You can seal small cracks or apply waterproof paint yourself, and that might help with minor moisture. But if you’re dealing with standing water, recurring leaks, or foundation cracks that keep coming back, DIY fixes won’t solve the root problem. You’ll spend money on products that don’t work and still end up calling someone like us.
Basement waterproofing isn’t just about stopping water you can see. It’s about managing hydrostatic pressure, directing groundwater away from your foundation, and installing drainage that actually handles New Hanover’s soil conditions. That requires equipment, experience, and an understanding of how water moves around your specific property.
The bigger risk is doing it wrong and causing more damage. If you install a sump pump in the wrong spot, or if your drainage doesn’t slope correctly, you can trap water instead of removing it. Then you’ve paid for materials and labor twice. Most homeowners save money in the long run by hiring a professional the first time.
Yes, but only if the mold isn’t already there. Waterproofing stops new water from getting in, which eliminates the moisture mold needs to grow. If your basement stays dry, mold can’t take hold. That’s especially important in New Hanover where humidity levels stay high and basements are naturally damp even without visible leaks.
If you already have mold, waterproofing won’t kill it. You’ll need mold remediation first, which involves removing contaminated materials, treating affected areas, and improving ventilation. Once that’s done, waterproofing keeps it from coming back by controlling the moisture source.
Mold isn’t just a cosmetic issue. It affects your home’s air quality and can trigger respiratory problems, especially in kids or anyone with asthma. A dry basement improves the air throughout your house because your HVAC system pulls air from lower levels. Fixing the water problem fixes the mold problem long-term.
Interior waterproofing manages water after it’s entered your foundation walls but before it floods your basement. We install drainage systems along the inside perimeter of your basement floor that collect water and direct it to a sump pump. It’s less invasive, costs less, and works well for most homes in New Hanover.
Exterior waterproofing involves excavating around your foundation, applying a waterproof membrane to the outside of your walls, and installing drainage tile at the footing level. It stops water before it ever touches your foundation, which is ideal but also expensive and disruptive. You’re tearing up landscaping, driveways, and anything else in the way.
Most homeowners here don’t need exterior work unless their foundation walls are severely damaged or they’re dealing with extreme water issues. Interior systems handle the majority of problems effectively and come with the same long-term protection. We’ll tell you honestly which approach makes sense for your situation and your budget.
