You’re not dealing with puddles in your basement because it’s fun. You’re dealing with them because water found a way in, and every time it rains, you’re wondering if it’ll happen again.
When you work with us as your waterproofing contractor in Franconia, PA, the outcome is simple: your basement stays dry. Not just for a season, but year after year. You stop worrying about mold growing behind your walls or your foundation getting worse. You stop moving boxes off the floor every time storms roll through.
Your home’s value stays intact. Your air quality improves. Your stress drops. And if you ever sell, you’ve got a Lifetime Transferable Warranty that tells the next owner this problem was handled right. That’s what happens when the root cause gets fixed, not just the symptoms.
Del Val Basement Waterproofing is a family-owned waterproofing company serving Franconia, PA and the surrounding Delaware Valley. We’re not a franchise. We’re not a call center that dispatches whoever’s available. When you call us, you’re talking to people who’ve been doing this work for years and who’ll be here next year when you need us.
Franconia sits in an area where clay soil, seasonal rainfall, and aging homes create the perfect recipe for basement moisture problems. We’ve seen it all here: foundation cracks from settling, sump pumps that can’t keep up, exterior drainage that was never designed for Montgomery County weather. We know what works in this area because we’ve been fixing these problems in homes just like yours.
First, we come out and inspect your basement and foundation. We’re not there to sell you the most expensive option. We’re there to figure out where the water’s coming from and why. That means looking at your foundation walls, checking your drainage, testing your sump pump, and walking your property to see how water moves around your home.
Once we know what’s causing the problem, we explain it to you in plain terms. No jargon. No pressure. Just a clear breakdown of what’s wrong and what it’ll take to fix it. If you need interior waterproofing, exterior drainage work, foundation repair, or a combination, we’ll tell you exactly what we recommend and why.
Then we schedule the work. Our trained installers handle the job from start to finish. We install the system, test it, clean up, and make sure you understand how everything works. And because we back our work with a Lifetime Transferable Warranty, you’re covered long after we leave.

When you hire us as your residential waterproofing company in Franconia, PA, you should know exactly what you’re getting. We handle basement waterproofing with interior drainage systems that collect water before it floods your floor. We install and replace sump pumps that actually work when you need them most. We repair foundation cracks and structural issues that let water seep through your walls.
If your problem is outside, we design and install exterior drainage solutions. That might mean catch basins, French drains, or grading work to redirect water away from your foundation. Franconia’s terrain and soil conditions mean every property drains differently. We don’t use cookie-cutter solutions. We assess your property’s slope, runoff patterns, and existing drainage, then build a system that handles your specific situation.
We also handle mold remediation when moisture has already caused damage. Mold doesn’t just smell bad. It affects your family’s health and your home’s air quality. We remove it, treat the area, and fix the moisture problem so it doesn’t come back. Every service we provide is designed to solve the root cause, not just cover up the symptoms.
If you’re seeing water in your basement after it rains, that’s the obvious sign. But there are others that show up before the flooding starts.
Musty smells mean moisture is getting in somewhere, even if you’re not seeing puddles. White powdery residue on your foundation walls is efflorescence, which happens when water pushes through concrete and leaves mineral deposits behind. Cracks in your foundation, especially horizontal ones or cracks wider than a quarter-inch, are letting water in and could be getting worse. Peeling paint, warped baseboards, or damp spots on your walls and floors all point to moisture problems that need attention.
If your sump pump runs constantly or doesn’t run at all during heavy rain, that’s a problem. And if you’ve tried fixing the issue yourself with sealants or dehumidifiers but the problem keeps coming back, it’s because the root cause hasn’t been addressed. That’s when you need us as your waterproofing contractor in Franconia, PA to identify where the water’s coming from and stop it for good.
Interior waterproofing manages water that’s already making its way into your basement. We install drainage systems along the inside perimeter of your foundation that collect water and channel it to a sump pump, which then pumps it out and away from your home. This method works well when the problem is groundwater seeping through your foundation or floor joints. It’s also less invasive than exterior work because we’re not excavating around your entire house.
Exterior waterproofing stops water before it reaches your foundation. This involves excavating around the outside of your home, applying a waterproof membrane or coating to your foundation walls, and installing drainage systems like French drains or catch basins to redirect water away from your home. Exterior solutions are often necessary when you’ve got significant foundation cracks, poor grading, or heavy runoff that’s overwhelming your property.
Sometimes you need both. If your foundation walls are cracked and leaking, and your yard isn’t draining properly, interior drainage alone won’t solve it. As your waterproofing company in Franconia, PA, we’ll assess your specific situation and recommend what actually makes sense for your home and budget, not just the most expensive option.
It depends on what’s causing your water problem and what it takes to fix it. Interior drainage systems with a sump pump typically start around a few thousand dollars for a standard basement. Exterior waterproofing with excavation and drainage work costs more because of the labor and scope involved. Foundation crack repair can range from a few hundred dollars for a simple injection to several thousand if you’ve got structural issues that need serious attention.
The size of your basement, the severity of the problem, and the type of solution you need all affect the price. A small crawl space with minor seepage costs less to waterproof than a full finished basement with multiple entry points and foundation damage. If your property has drainage issues that require grading work or extensive exterior systems, that adds to the cost.
Here’s what matters: cheap fixes don’t last. If someone’s offering to seal your basement for a few hundred bucks, you’re going to be calling someone else in a year when it fails. We price our work based on what it actually takes to solve your problem permanently, and we back it with a Lifetime Transferable Warranty. You can call us for a free inspection and we’ll give you a clear, honest estimate with no pressure to decide on the spot.
Most interior waterproofing jobs take one to three days depending on the size of your basement and the complexity of the work. If we’re installing a perimeter drainage system and a sump pump in a standard basement, we can usually finish in a day or two. Larger basements or homes that need multiple sump pumps or extensive drainage work take longer.
Exterior waterproofing takes more time because of the excavation involved. Digging around your foundation, applying waterproof coatings, installing drainage systems, and backfilling can take anywhere from three days to a week or more. Weather plays a role too. If it’s pouring rain, we’re not excavating your yard. We’ll schedule the work when conditions allow us to do it right.
Foundation crack repair is usually faster. Simple crack injections can be done in a few hours. Structural repairs that involve reinforcement or extensive work take longer. When you call us as your waterproofing contractor in Franconia, PA for an estimate, we’ll give you a realistic timeline based on your specific project. We’re not going to rush the job just to move on to the next one. We’re going to do it right so you don’t have to call us back.
Yes, if the waterproofing actually stops the moisture. Mold grows when there’s moisture and organic material for it to feed on. Your basement has plenty of organic material: wood framing, drywall, carpet, cardboard boxes. If water keeps getting in, mold will keep growing no matter how many times you clean it up.
When you fix the water problem at its source, you eliminate the conditions mold needs to thrive. Interior drainage systems keep groundwater from pooling on your floor. Exterior waterproofing stops water from seeping through your foundation walls. Sump pumps remove water before it can sit and create humidity. When your basement stays dry, mold doesn’t have the moisture it needs to grow.
If you already have mold, waterproofing alone won’t remove it. You need mold remediation to clean up what’s there, treat the affected areas, and make sure spores aren’t spreading through your home’s air. We handle both: we’ll remove the mold and fix the moisture problem so it doesn’t come back. A dry basement is a healthy basement, and that’s what you get when you work with us as the best waterproofing company in Franconia, PA that understands how moisture and mold work together.
Yes. We back all our waterproofing work with a Lifetime Transferable Warranty. That means if our system fails, we come back and fix it at no cost to you. And if you sell your home, the warranty transfers to the next owner, which is a selling point that adds value to your property.
Most waterproofing companies either don’t offer warranties, or they offer short-term warranties with so many exclusions they’re basically useless. We’re a family-owned business that’s been serving the Delaware Valley for years. We’re not going anywhere, and we stand behind our work because we know it’s going to last.
The warranty covers our workmanship and the systems we install. If your sump pump fails because of a defect or our drainage system stops working, we’ll make it right. The only things not covered are damage from things outside our control, like major structural changes to your home or natural disasters. When you hire us as your local waterproofing company in Franconia, PA that actually backs our work, you’re not just paying for a service. You’re investing in long-term protection and peace of mind.
