You stop worrying every time rain hits the forecast. Your basement smells normal again—no more musty air creeping upstairs through the vents. You can actually use that space for storage, a home gym, or an extra room without wondering if everything’s going to get soaked.
The constant stress lifts. No more checking the basement during storms or dealing with wet carpet and ruined boxes. Your foundation stays stable instead of slowly deteriorating from water pressure and cracks.
If you’ve been dealing with water in your basement after heavy rain, you already know how exhausting it gets. A proper waterproofing system handles what Pennsylvania throws at it—spring downpours, snowmelt in March, clay soil that holds water like a sponge. You get your peace of mind back, and your home stays protected for the long term.
Del Val Basement Waterproofing is a family-run waterproofing company serving Elkins Park, PA and the surrounding areas. We started in this industry because helping homeowners solve foundation and water problems is genuinely satisfying work—especially when you see someone finally get relief after years of dealing with a wet basement.
We’re not the biggest operation, and we’re not trying to be. What you get is straightforward pricing, a lifetime transferable warranty on our work, and a team that treats your foundation like it’s our own. We’ve been doing this for over 15 years across Montgomery County and the greater Philadelphia area.
Elkins Park homes face specific challenges—older construction, clay-heavy soil, high water tables in certain areas. We’ve seen it all, and we know what actually works here versus what’s just going to fail again in five years.
First, we come out for a free estimate. We’re looking at where water’s getting in, what’s causing it, and what your specific property needs—not just trying to sell you the most expensive option. You’ll get a clear explanation of what we found and what we recommend.
Once you’re ready to move forward, we schedule the work around your life. Most jobs don’t require you to leave your house. Yes, there’s some noise and dust, but it’s manageable. We’re usually talking about a few days depending on the scope—interior drainage systems, exterior waterproofing, sump pump installation, whatever your situation calls for.
We install systems designed to last for decades. If you need a sub-floor pressure relief system, that’s what we do—it’s a proven alternative to old French drains that may have already failed on you. After installation, we test everything, clean up, and walk you through what we did. Then you get your lifetime transferable warranty, and you’re done worrying about water in your basement.

You’re getting interior and exterior waterproofing systems that handle the specific conditions in Elkins Park, PA. That means dealing with Pennsylvania’s clay soil, fluctuating temperatures, and the reality that 98% of basements will experience some level of water damage at some point.
We install sump pumps, interior drainage systems, exterior waterproofing membranes, foundation crack repair—whatever your home needs. The goal isn’t just to stop water right now. It’s to prevent the problem from coming back and causing structural damage, mold growth, or health issues down the road.
Elkins Park sits in an area where spring storms and snowmelt create serious water intrusion risks. Older homes in the area weren’t always built with modern waterproofing standards. We’re fixing that gap. You also get our lifetime transferable warranty, which means if you sell your home, that protection transfers to the next owner—a real selling point when it’s time to move.
The average cost for basement waterproofing runs between $3,000 and $10,000 depending on what’s needed. That’s a fraction of what you’d pay for water damage repairs, mold remediation, and foundation fixes if you let the problem go. We’re not the cheapest option you’ll find, but we’re the one that actually lasts.
Most waterproofing systems we install are designed to last for the life of your home—we’re talking decades, not years. The longevity depends on the type of system and how well it’s installed in the first place.
Interior drainage systems, when done right, can last 20 to 30 years or more without major maintenance. Exterior waterproofing membranes also hold up for decades if they’re applied correctly and the drainage around your foundation is managed properly. Sump pumps need occasional checks and might need replacement every 10 to 15 years depending on how hard they’re working, but that’s routine maintenance.
The key is getting a system that’s built for Pennsylvania’s conditions—clay soil, freeze-thaw cycles, heavy spring rains. Cheap installations or outdated methods like basic French drains tend to fail much sooner, which is why we use sub-floor pressure relief systems and proven techniques that hold up over time. Our lifetime transferable warranty backs that up.
Yes, you can stay in your house during the waterproofing process. It’s not invasive enough to force you out, and most families continue their normal routines while we work.
You’ll hear some noise—jackhammering if we’re installing an interior drainage system, equipment running, that kind of thing. There will be some dust, though we do our best to contain it and clean up as we go. The work usually takes a few days depending on the scope of the project.
The biggest disruption is just having crew members on-site and needing access to your basement or exterior foundation areas. We communicate the timeline upfront so you know what to expect each day. If you work from home or have young kids, it’s helpful to plan around the noisier parts of the job, but it’s not unmanageable. The short-term inconvenience is worth it when you consider you’re getting long-term protection against water damage and the stress that comes with it.
You’re risking structural damage, mold growth, and ongoing financial stress. Water doesn’t just sit in your basement and evaporate—it seeps into your foundation, weakens the structure over time, and creates conditions for mold and mildew to spread throughout your home.
Mold is a real health hazard, especially for kids, older adults, and anyone with asthma or allergies. Once it gets into your HVAC system, it circulates through your entire house every time the heat or AC kicks on. Mold remediation is expensive and complicated, and it only gets worse the longer you wait.
Financially, a single basement flooding event can cost anywhere from $1,600 to $6,900 in repairs—and that’s assuming you catch it early. If the water damages your foundation or causes structural issues, you’re looking at much higher costs. Pennsylvania’s unpredictable weather and clay-heavy soil make Elkins Park homes particularly vulnerable. The longer you put off waterproofing, the more likely you are to face one of these expensive emergencies. A waterproofing system is an investment that prevents all of that.
Most homeowners spend between $3,000 and $10,000 on basement waterproofing, depending on the size of the space, the severity of the water problem, and what type of system you need. Major repairs or exterior waterproofing can push costs higher, but that’s less common.
The price depends on whether you need interior drainage, exterior waterproofing, sump pump installation, foundation crack repair, or a combination of those. Every home is different. That’s why we do free estimates—we assess your specific situation and give you a clear number based on what actually needs to happen, not a generic quote.
It’s tempting to go with the cheapest option, but that usually means you’re getting a temporary fix that fails in a few years. Then you’re paying again to redo the work, plus dealing with any damage that happened in the meantime. We price our work fairly, and we back it with a lifetime transferable warranty. You’re paying once for a system that lasts, which ends up being the most cost-effective choice in the long run.
Pennsylvania’s weather is the biggest culprit—heavy spring rains, snowmelt in early March, and unpredictable storms that dump water faster than the ground can absorb it. Elkins Park sits in an area with clay-heavy soil, which holds water instead of draining it away from your foundation. That creates constant pressure against your basement walls.
Older homes in the area often have foundation cracks, outdated or nonexistent waterproofing, and poor drainage systems. When you combine that with a high water table in certain parts of Elkins Park, water finds its way in through cracks, joints, and porous concrete. Clogged gutters and downspouts that dump water right next to your foundation make the problem worse.
Flooding is the most common natural disaster in Pennsylvania, and basements are the most vulnerable part of your home. If you’re seeing water after every rainstorm, it’s not bad luck—it’s a drainage or waterproofing issue that needs to be fixed. The longer you wait, the more damage accumulates. A proper waterproofing system addresses the root cause so you’re not just reacting to every storm.
Yes, we offer a lifetime transferable warranty on our waterproofing work. That means if something goes wrong with the system we installed, we’ll come back and fix it at no additional cost. And if you sell your home, that warranty transfers to the next owner—which is a real selling point.
We stand behind our work because we use proven systems and experienced crews who’ve been doing this for years. We’re not cutting corners or using cheap materials that fail after a few seasons. Our goal is to install a waterproofing system that lasts for decades, and the warranty reflects that confidence.
Most waterproofing companies either don’t offer a warranty or limit it to a few years. Ours is lifetime and transferable because we know what we’re installing will hold up. If you’re comparing estimates, ask about the warranty. It’s one of the clearest indicators of whether a company actually believes in the work they’re doing or if they’re just trying to get in and out as fast as possible.
