You stop worrying every time rain hits. No more towels on the floor, no more moving boxes to higher shelves, no more wondering if this storm will be the one that floods your furnace or ruins what you’ve stored downstairs.
A dry basement means your home holds its value. It means the air upstairs stays cleaner because mold isn’t growing below. It means you can actually use that space—for storage, for a workshop, for whatever you need—without second-guessing whether it’ll be underwater next month.
When your basement is waterproofed correctly, you’re not calling for emergency repairs. You’re not dealing with insurance claims or replacing ruined belongings. You’re just living in your house without that constant low-level stress that comes from knowing water could show up anytime.
Del Val Basement Waterproofing is a family-run waterproofing contractor serving East Fallowfield, PA and the rest of Chester County for over 15 years. We’re not a franchise or a national chain—we’re local, and we’ve seen what spring rains and summer storms do to basements around here.
East Fallowfield sits in an area where groundwater doesn’t mess around. Between the clay-heavy soil and the way water moves through this part of Chester County, basements take a beating. We’ve worked on homes throughout the township, and we know what actually works versus what just delays the problem.
We back our work with a lifetime transferable warranty because we install systems designed to last as long as your house does. You’re not getting a temporary fix or something that’ll need replacing in five years.
First, we come out and figure out where the water’s coming from. That means looking at your foundation, checking grading around the house, and understanding how water moves on your property. Not every wet basement needs the same fix.
Most of the time, we’re installing an interior drainage system—specifically our Sub Floor Pressure Relief System. It’s a more reliable approach than old-style French drains. We’re cutting a channel along the inside perimeter of your basement floor, installing the drainage system, and connecting it to a sump pump that pushes water out and away from your foundation.
You can stay in your house while we work. It’s not a gut-job renovation. We’re typically done in a few days depending on the size of your basement, and we clean up when we’re finished. Once it’s in, you don’t need to do anything—the system runs on its own and handles water automatically whenever it shows up.
Ready to get started?
You’re getting a complete interior drainage system that intercepts water before it floods your basement floor. That includes the Sub Floor Pressure Relief System installed along your foundation walls, a sump pump that’s sized correctly for your home, and a discharge line that moves water far enough away that it doesn’t just loop back.
In East Fallowfield, where we see heavy spring rains and summer thunderstorms that dump inches in a short window, your system needs to handle sudden volume. We size everything based on your specific property—not a one-size-fits-all approach.
You’re also getting a lifetime transferable warranty. If you sell your house, the warranty goes with it, which is something buyers notice. And if you’ve got foundation cracks, mold issues, or crawl space moisture, we handle those too. Most basements around here need more than one thing addressed, and we’d rather fix it all correctly than leave you halfway protected.
Most homeowners in East Fallowfield spend between $3,000 and $10,000 depending on the size of the basement and what’s needed. A straightforward interior drainage system with a sump pump on a smaller basement sits closer to the lower end. Larger basements, homes that need exterior work, or situations where there’s foundation damage that needs fixing first will cost more.
The price depends on how much linear footage of drainage we’re installing, whether your sump pump needs a battery backup (smart idea if you lose power during storms), and if there are complications like finished walls we need to work around. We give you an exact number after we assess your basement—not a range or an estimate that changes later.
Cheaper options exist, but they usually involve shortcuts that don’t last. You’re paying for a system that works for decades and a warranty that actually means something if there’s ever an issue.
Most installations take two to four days depending on your basement size and what we’re doing. A standard interior drainage system on an average-sized basement usually wraps up in two to three days. Larger spaces or jobs that include exterior waterproofing, foundation repair, or crawl space work take longer.
You don’t need to leave your house while we work. The process is messy in the sense that we’re cutting concrete and moving equipment, but it’s contained to the basement. We’re not tearing apart your whole house or making it unlivable.
Once we’re done, the system is operational immediately. You don’t need a break-in period or time for anything to cure before it starts protecting your basement. The next time it rains, the system’s already handling water.
If the system is installed correctly and addresses the actual source of your water problem, yes. But that depends on diagnosing the issue right in the first place. Some water problems come from groundwater pressure pushing through your foundation—that’s what interior drainage systems handle. Other problems come from surface water that’s not being directed away from your house, which means we need to address grading or downspouts.
In East Fallowfield, most wet basements are dealing with groundwater, especially during spring when the water table rises and soil stays saturated for weeks. An interior system intercepts that water and removes it before it floods your floor. But if you’ve also got cracks in your foundation or window wells that fill up during storms, those need separate attention.
We assess everything during the initial visit so you know exactly what’s causing water intrusion and what it takes to stop it. A good waterproofing company doesn’t just install a drain and hope for the best—we make sure the solution matches the problem.
Interior waterproofing manages water after it’s entered your foundation but before it floods your basement. We install drainage along the inside perimeter that captures water and pumps it out. It’s less invasive, more affordable, and just as effective for most situations. You don’t need to excavate around your entire house or disrupt your landscaping.
Exterior waterproofing involves digging down to your foundation from the outside, applying a waterproof membrane or coating, and installing drainage at the footing level. It stops water before it touches your foundation walls. It works, but it’s expensive, disruptive, and often unnecessary unless your foundation walls are severely compromised.
For most homes in East Fallowfield dealing with typical groundwater issues, interior waterproofing is the smarter move. It costs less, gets installed faster, and handles the problem just as reliably. Exterior work makes sense in specific situations—like if your foundation walls are crumbling or if there’s no way to manage water from the inside—but those cases are rare.
Yes. The drainage system collects the water, but the sump pump is what removes it from your basement. Without a pump, water just sits in the drainage system with nowhere to go. The two work together—the drain captures water seeping through your foundation, channels it to a sump basin, and the pump pushes it outside and away from your house.
We install sump pumps that are properly sized for your basement and the amount of water your property deals with. Undersized pumps burn out or can’t keep up during heavy rain. Oversized pumps cycle on and off too frequently and wear out faster. Getting the sizing right matters.
Battery backup is worth considering, especially in East Fallowfield where storms can knock out power. If your pump loses electricity during a heavy rain, your basement floods anyway. A backup system keeps the pump running even when the power’s out, which is exactly when you need it most.
If water is already getting into your basement—puddling on the floor, seeping through cracks, or leaving water stains on your walls—you need waterproofing. Better drainage outside helps, but it’s not enough once water is breaching your foundation. You need an interior system to intercept and remove it.
If you’re not getting water inside yet but your gutters overflow, downspouts dump right next to your foundation, or your yard slopes toward your house, fixing those things first makes sense. Proper grading and downspout extensions can prevent water from ever reaching your foundation in the first place.
Most homes in East Fallowfield benefit from both. Even with perfect grading, groundwater pressure during wet seasons can still push through foundation walls. We look at the whole picture when we assess your property—what’s happening outside and what’s happening inside—so you’re not spending money on fixes that don’t address the real issue.
