You stop worrying every time it rains. Your basement stays dry, your air quality improves, and you’re not dealing with that musty smell anymore.
The stuff you store down there is safe. Your foundation isn’t cracking under pressure. And if you ever sell, you’ve got a lifetime transferable warranty that tells buyers this house was protected the right way.
Villanova gets 45 inches of rain a year. That’s a lot of water trying to find its way into your basement. When your waterproofing system is working, that water goes somewhere else. When it’s not, you’re looking at damaged belongings, health risks from mold, and repair bills that climb fast.
Del Val Basement Waterproofing is family-run, and we’ve been serving homeowners across the Delaware Valley for years. We’re based in Plymouth Meeting, and we know what Villanova basements deal with.
Older homes. Clay soil. Heavy spring rains. These aren’t surprises to us.
We’re not the biggest basement waterproofing company in Villanova, PA, and that’s intentional. You get the owner’s cell number. You get a crew that shows up when they say they will. And you get a lifetime warranty on the work, because we’re not going anywhere.
We start with an inspection. We’re looking at where the water’s coming in, what’s causing it, and what your foundation looks like. Cracks, hydrostatic pressure, grading issues—we need to see it all before we recommend anything.
Once we know what’s going on, we design a system that fits your home. That might mean interior drainage with a sump pump. It could be exterior waterproofing to relieve pressure on your foundation walls. Or both.
The install is straightforward. We’re not tearing your house apart. Most homeowners stay in the house while we work. We set up the drainage system, install the sump pump if needed, seal the walls, and test everything before we leave. You’ll know exactly how it works and what to expect long-term.

You’re getting a system designed for your specific basement. That includes our Sub Floor Pressure Relief System, which is more reliable than the old French drains most basement waterproofing contractors in Villanova, PA still use. It manages groundwater before it ever reaches your walls.
We install high-capacity sump pumps with battery backup. When the power goes out during a storm, your basement stays protected. We also seal foundation cracks, address any mold issues, and make sure your exterior grading isn’t sending water straight toward your house.
Villanova’s older homes weren’t built with modern waterproofing. The foundations are aging, and the soil here holds water. That’s why we don’t use one-size-fits-all approaches. Your system is built around what your home actually needs, not what’s easiest to install.
And everything comes with a lifetime transferable warranty. If you sell, the new owner is covered. That’s how confident we are in the work.
Most homeowners spend between $3,000 and $10,000, but it depends on what your basement needs. A straightforward interior drainage system with a sump pump is on the lower end. Exterior waterproofing, foundation repair, or dealing with major structural issues costs more.
We don’t give quotes over the phone because every basement is different. The size of your home matters. So does the severity of the water problem, the condition of your foundation, and whether you need mold remediation.
What you’re really paying for is a system that lasts decades and a warranty that transfers if you sell. Cheap fixes don’t work here. You’ll end up paying twice.
A properly installed system lasts the life of your home. Our Sub Floor Pressure Relief Systems and sump pumps are built to run for decades without major maintenance.
You’ll want to check your sump pump once a year. Make sure it’s cycling properly and the backup battery is charged. Beyond that, the system just works.
That’s why we offer a lifetime warranty. We’re not expecting callbacks. The materials are commercial-grade, the installation is done right, and we’ve been doing this long enough to know what holds up in Villanova’s soil and weather conditions.
Yes. Most of our work is in the basement, and it’s not invasive. You can keep your normal routine while we’re installing the system.
There will be some noise. We’re breaking concrete to install drainage lines, and we’ll have equipment running. But we’re not shutting off your water or electricity for days at a time.
The timeline depends on the scope of work. Interior waterproofing usually takes a few days. Exterior work takes longer because we’re excavating around the foundation. We’ll give you a clear schedule before we start so you know what to expect.
Interior waterproofing manages water that’s already trying to get in. We install drainage systems along the perimeter of your basement floor, direct the water to a sump pump, and pump it out. It’s effective, less invasive, and costs less than exterior work.
Exterior waterproofing stops water before it reaches your foundation. We excavate around the outside of your home, apply a waterproof membrane to the walls, install drainage, and regrade if needed. It’s more comprehensive, but it’s also more disruptive and expensive.
Most homes in Villanova, PA need interior waterproofing. Exterior work makes sense if your foundation walls are deteriorating, if you’re dealing with severe hydrostatic pressure, or if interior solutions aren’t enough. We’ll tell you which approach fits your situation.
Yes, if the water problem is fixed. Mold grows when moisture is present. Stop the moisture, and you stop the mold.
If you already have mold, we’ll address that during the waterproofing process. We remove contaminated materials, treat affected areas, and make sure your humidity levels drop once the system is running.
Villanova’s humidity makes basements a perfect environment for mold if water is getting in. Once your basement is dry, mold doesn’t have what it needs to grow. You’ll notice the air quality improves pretty quickly after the system is installed.
You’ll see signs. Water pooling on the floor after it rains. Damp spots on the walls. That musty smell that won’t go away. Efflorescence, which looks like white powder on your concrete, means water is pushing through your foundation.
Cracks in your foundation walls are another indicator, especially if they’re horizontal or widening. That’s hydrostatic pressure at work, and it’s not something you ignore.
If you’re not sure, we’ll come out and inspect. We’ll tell you if you need a full waterproofing system or if it’s something simpler. Either way, you’ll know what you’re dealing with and what it’ll take to fix it.
