You stop worrying every time rain’s in the forecast. No more moving boxes off the floor or running downstairs during storms to check for water.
Your basement becomes usable space again—not a liability. You’re not dealing with that musty smell or wondering if mold’s growing behind stored furniture. The air quality improves throughout your whole house because moisture isn’t creeping up from below.
And when you eventually sell, you’re not explaining away water stains or hoping buyers don’t notice the dehumidifier running 24/7. A french drain system in New London, PA protects your foundation from hydrostatic pressure that builds up in our clay-heavy soil. That pressure—sometimes hundreds of pounds against your foundation walls—causes cracks, bowing, and the kind of structural damage that costs serious money to fix later.
Del Val Basement Waterproofing is a family-run company that’s handled over fifteen years of Pennsylvania basements. We know what New London soil does to foundations—how it expands when wet, contracts when dry, and pushes against your walls with every season change.
We’re not the cheapest option, and that’s intentional. You’re getting residential french drain installation in New London, PA that comes with a lifetime transferable warranty. That means we’re still accountable years from now, whether you own the house or not.
We don’t use pressure tactics or same-day-only pricing. You get a straightforward assessment, honest pricing, and installation that’s done right the first time.
We start with a site assessment to see where water’s collecting and how it’s moving around your foundation. That tells us where the french drain drainage system installation in New London, PA needs to go and how deep it needs to be.
Next, we excavate a trench along the problem areas—usually around your foundation’s perimeter or wherever water pools in your yard. The trench gets lined with filter fabric, then filled with gravel and a perforated pipe that captures water before it reaches your foundation. We slope everything so water flows away from your house, either to a safe drainage point on your property or into a sump system.
The whole process typically takes about a week, depending on your property size and how much drainage work you need. We restore any landscaping we disturb and make sure everything’s graded properly so surface water moves in the right direction too.

A french drain to stop flooding in New London, PA isn’t just a pipe in the ground. You’re getting a complete exterior drainage solution designed for Pennsylvania’s weather patterns and soil conditions.
We install commercial-grade perforated pipe that won’t collapse or clog over time. The system includes proper filter fabric to keep soil out while letting water through, and we use clean gravel that creates the drainage channels water needs to flow freely. Everything’s sloped correctly—because a french drain that doesn’t drain isn’t worth the excavation cost.
New London sits in an area where spring rains and summer downpours drop water faster than clay soil can absorb it. That’s why we size and position your drainage system based on your specific property—how water flows across your lot, where your foundation’s most vulnerable, and what your soil does when it gets saturated. This isn’t a one-size-fits-all installation. It’s engineered to prevent basement water with french drain systems that match your property’s actual drainage challenges.
Most residential french drain installation in New London, PA runs between $3,000 and $7,000, depending on how much drainage work your property needs. That’s based on the linear footage we’re installing, how deep we need to go, and whether you need additional components like a sump pump system.
The cost breaks down to roughly $26 to $41 per linear foot in Pennsylvania. A typical installation around a foundation perimeter might be 100 to 150 feet, but your property could need more or less.
We give you a detailed estimate after assessing your property—no ballpark guesses. You’ll know exactly what you’re paying for and why each component matters. The lifetime transferable warranty is included in that price, which matters when you’re comparing quotes from other contractors.
A properly installed french drain system in New London, PA should last 20 to 30 years or longer. The lifespan depends on installation quality, the materials used, and how well the system’s maintained.
Cheap installations fail faster—usually because contractors skip the filter fabric, use undersized pipe, or don’t create proper slope. When soil gets into the pipe or water can’t flow freely, the system clogs and stops working within a few years.
We install systems built to handle Pennsylvania’s soil conditions long-term. That means quality materials, correct depth, proper grading, and filter fabric that keeps soil out while letting water through. We also make sure your downspouts and surface drainage work with your french drain, not against it. Most failures happen when surface water overwhelms the system because nobody addressed where roof runoff goes.
A french drain installation in New London, PA stops water from reaching your foundation in the first place—which is how you prevent basement flooding. It intercepts groundwater and surface runoff before pressure builds up against your foundation walls.
If you’re already getting water in your basement during heavy rain, that’s usually because water’s pooling around your foundation and finding its way through cracks, joints, or porous concrete. A french drain system eliminates that pooling by capturing water and redirecting it away from your house.
For basements that flood from groundwater rising up through the floor, you might also need an interior drainage system or sump pump. We assess your specific situation and tell you exactly what’ll fix your problem. Sometimes it’s just the exterior french drain. Sometimes it’s a combination approach. Either way, you’re not guessing—you’re getting a solution based on where your water’s actually coming from.
An exterior french drain in New London, PA stops water before it reaches your foundation. An interior system manages water that’s already getting into your basement. They solve different problems.
Exterior french drains are installed outside your foundation walls, usually at footing level. They intercept groundwater and surface runoff, redirecting it before hydrostatic pressure builds up against your foundation. This is the preferred approach because you’re preventing the problem, not just managing it after water’s already there.
Interior french drains get installed inside your basement along the perimeter, underneath the floor slab. They collect water that’s coming up through the floor or through foundation walls, then pump it out with a sump system. This works when exterior installation isn’t feasible or when you need to address existing water intrusion quickly. We typically recommend exterior french drain services in New London, PA when possible, because keeping water away from your foundation protects the structure long-term and keeps your basement drier overall.
If you’re getting water in your basement during or after rain, you probably need a french drain installation in New London, PA. Same goes if you have standing water around your foundation, soggy areas in your yard that won’t dry out, or water stains on your basement walls.
Other signs include musty smells in your basement, efflorescence (white mineral deposits) on foundation walls, or cracks that seem to be getting worse. These all point to water pressure building up around your foundation—exactly what french drain systems are designed to prevent.
Pennsylvania’s clay soil makes drainage problems worse because water doesn’t absorb quickly. It sits around your foundation, building pressure and finding ways inside. If your house was built before the 1980s, there’s a good chance you don’t have adequate foundation drainage at all. Older homes in New London weren’t built with the drainage systems we install today. A professional assessment tells you for sure—we look at your property’s grading, where water collects, and what’s happening with your foundation.
You can dig a trench and lay pipe yourself, but professional french drain installation in New London, PA involves more than most homeowners realize. Getting the depth right, creating proper slope, sizing the system correctly, and connecting everything so water actually drains—that’s where DIY projects usually fail.
Pennsylvania soil conditions make this harder. You’re dealing with clay that doesn’t drain well, frost lines that affect how deep you need to go, and grading challenges that aren’t obvious until you’re already digging. If your french drain doesn’t slope correctly or the pipe’s not sized right for your property’s water volume, you’ve just spent days digging for a system that won’t work.
There’s also the question of where water goes once your french drain collects it. If you’re directing it toward your neighbor’s property or into areas that cause other problems, you’re creating liability. We handle permitting when needed, make sure drainage complies with local codes, and engineer the system so water goes where it’s supposed to. The lifetime warranty means you’re not on your own if something doesn’t work right.
