You stop worrying every time the forecast calls for rain. You’re not hauling wet boxes out of storage or running a dehumidifier that barely keeps up. Your kids can play downstairs without you thinking about what’s growing behind the walls.
A dry basement means your home value doesn’t tank when it’s time to sell. It means your HVAC system isn’t working overtime to fight humidity. And it means you’re not looking at a $20,000 foundation repair bill three years from now because water kept doing what water does—finding its way in and breaking things down.
Upper Pottsgrove sits on clay-heavy soil. That means hydrostatic pressure builds up fast when it rains, and your basement takes the hit. You need a system that actually handles that pressure, not a temporary patch that fails next spring.
Del Val Basement Waterproofing is a family-run waterproofing contractor serving Upper Pottsgrove, PA and the surrounding counties. We’ve spent over 15 years dealing with Pennsylvania’s clay soil, fluctuating water tables, and the kind of storms that turn basements into swimming pools.
We’re not the cheapest option you’ll find—and that’s actually a good thing for you. You’re paying for a system designed to last as long as your house stands, backed by a lifetime transferable warranty. That means fewer callbacks, no repeat flooding, and one less thing to worry about when the next storm rolls through.
Upper Pottsgrove homeowners deal with specific challenges. Older foundations, high water tables, and soil that holds moisture like a sponge. We’ve seen it all, and we know what works here.
First, we come out for a free inspection. We’re looking at where the water’s coming in, what’s causing it, and what it’s going to take to stop it for good. You get a clear explanation and a written estimate—no surprises later.
Once you’re ready to move forward, we install a sub-floor pressure relief system. This isn’t a French drain that clogs up in five years. It’s engineered to handle hydrostatic pressure and groundwater intrusion, which is exactly what Upper Pottsgrove basements deal with. We also install sump pumps, seal foundation cracks, and address any exterior drainage issues that are feeding the problem.
The work itself is non-invasive. You don’t have to move out. We keep disruption to a minimum, clean up when we’re done, and make sure everything’s working before we leave. Then you wait for the next big rain—and your basement stays dry.

You get interior and exterior waterproofing options depending on what your home needs. That includes basement waterproofing, crawl space encapsulation, foundation crack repair, and sump pump installation. Every system is designed to handle Pennsylvania’s soil conditions and weather patterns.
Upper Pottsgrove sees an average of one flood event per year across the region. Your home is sitting in an area where water doesn’t drain away easily, and older foundations weren’t built with modern waterproofing standards. That’s why a basic sealant won’t cut it. You need a system that redirects water before it ever reaches your foundation walls.
We also address the clay bowl effect—a common issue in this area where backfilled soil around your foundation creates a basin that traps water. Our drainage systems relieve that pressure and give the water somewhere else to go. You’re not just keeping water out. You’re changing how water behaves around your home.
And because we back everything with a lifetime transferable warranty, you’re covered if anything goes wrong. That warranty transfers to the next owner if you sell, which makes your home easier to move and more valuable when you do.
Most residential waterproofing projects in Upper Pottsgrove run between $3,000 and $10,000 depending on the size of your basement, the severity of the water intrusion, and whether you need interior or exterior work. A basic interior system with a sump pump and drainage typically starts around $4,000. If you need foundation crack repair, exterior excavation, or crawl space encapsulation, costs go up from there.
Philadelphia-area pricing runs about 10-15% higher than the national average due to labor rates and demand. But here’s the thing—you’re not just paying to keep water out. You’re avoiding a much bigger bill down the road. A $5,000 waterproofing system today can prevent $20,000 in foundation repairs or mold remediation later.
We give you a written estimate after the inspection so you know exactly what you’re paying for. No hidden fees, no upsells once we start the job.
A properly installed waterproofing system should last as long as your house does. Our sub-floor pressure relief systems are built to handle decades of use without major maintenance. Sump pumps typically last 7-10 years depending on how often they run, but the drainage system itself doesn’t wear out.
Pennsylvania’s clay soil and fluctuating water tables put more stress on foundations than in other parts of the country. That’s why the quality of the installation matters so much. A system that’s designed for these conditions—and installed correctly the first time—won’t need to be redone in five years.
We back our work with a lifetime transferable warranty, which means if something fails, we come back and fix it. That’s not something you get with a cheap patch job or a DIY sealant from the hardware store.
Interior waterproofing manages water after it’s already trying to get in. We install a drainage system along the inside perimeter of your basement that captures water and directs it to a sump pump. This is less invasive, more affordable, and works well for most homes in Upper Pottsgrove.
Exterior waterproofing stops water before it reaches your foundation. We excavate around the outside of your home, apply a waterproof membrane to the foundation walls, and install exterior drainage. It’s more expensive and disruptive, but it’s necessary if your foundation walls are severely cracked or if water pressure is too high for an interior system to handle alone.
Most homeowners don’t need full exterior waterproofing. We’ll tell you during the inspection if you do. If an interior system will solve the problem, that’s what we’ll recommend. We’re not here to sell you more than you need.
Yes—if you catch it before mold takes over. Mold starts growing within 24-48 hours after water intrusion. Once your basement is dry and stays dry, mold doesn’t have the moisture it needs to spread. But if there’s already mold behind your walls or in your insulation, waterproofing alone won’t remove it. You’ll need mold remediation first.
Mold is a serious issue in Upper Pottsgrove because of how much moisture the soil holds. When water seeps into your basement, it creates the perfect environment for mold to grow. And because most HVAC systems pull air from the basement, those spores spread throughout your entire home.
A dry basement eliminates that risk. You’re not just protecting your foundation—you’re protecting your family’s health. If you’ve got kids, elderly family members, or anyone with asthma or allergies, this matters even more.
You can try, but it’s not likely to work long-term. DIY waterproofing products like sealants and epoxy crack fillers might stop a small leak temporarily, but they don’t address the root cause—hydrostatic pressure pushing water through your foundation. Upper Pottsgrove’s clay soil makes that pressure worse, which is why surface-level fixes fail.
A real waterproofing system requires excavation, proper drainage installation, sump pump setup, and an understanding of how water moves around your foundation. If any part of that is done wrong, you’re back to square one the next time it rains hard.
The bigger risk is that a failed DIY job can actually make things worse. Water finds new paths, cracks spread, and you end up paying more to fix the original problem plus the damage caused by the failed repair. It’s worth getting it done right the first time.
If your basement floods during heavy rain, you need a sump pump. If you see water pooling on your basement floor, you need a sump pump. If your basement smells damp even when it’s not raining, you probably need a sump pump.
A sump pump is the last line of defense in a waterproofing system. It sits in a basin at the lowest point of your basement and pumps water out before it can flood your space. In Upper Pottsgrove, where water tables rise quickly during storms, a sump pump isn’t optional—it’s necessary.
We install sump pumps as part of most waterproofing jobs. We also recommend battery backup systems so the pump keeps working even if you lose power during a storm. Because the last thing you need is a flooded basement in the middle of a blackout.
