You stop worrying every time it rains. Your finished basement doesn’t flood. Your storage stays dry, your air smells clean, and you’re not dealing with mold or that damp feeling that never quite goes away.
A properly waterproofed basement means you can actually use the space. You’re not constantly running a dehumidifier or replacing ruined boxes. You’re not calling your insurance company or scrambling with towels when a storm rolls through Kennett.
The foundation stays stable. The walls stay intact. Your home value doesn’t take a hit because buyers see water stains or smell moisture. You’ve handled the problem the right way, and it shows.
We’re a family-run waterproofing company that’s been serving homeowners in Kennett, PA and the greater Philadelphia area for over 15 years. We’re not a national franchise that rotates crews—we’re local, licensed, and we’ve seen what Chester County soil and weather do to foundations.
Kennett sits in an area where clay soil creates hydrostatic pressure and unpredictable storms dump water faster than the ground can absorb it. We know the basements here. We know what fails and what actually holds up.
Every job gets a lifetime transferable warranty. We train our own inspectors and installers. And we don’t disappear after the work is done—we’re still here if something comes up.
First, we inspect your basement to figure out where the water’s coming from. That might be through foundation cracks, around the floor joint, or because your drainage system isn’t keeping up. We don’t guess—we look at grading, soil saturation, sump pump performance, and how your home sits on the lot.
Once we know the source, we recommend either interior waterproofing, exterior waterproofing, or both. Interior systems involve installing drainage along the footer and a sump pump to move water out. Exterior work means excavating around the foundation, sealing the walls, and installing proper drainage to redirect water before it ever reaches your basement.
The install is done by our trained crew. We don’t subcontract the work. You’ll see the same people from start to finish. When we’re done, we clean up, test the system, and walk you through how everything works. Then we back it with a lifetime warranty that transfers if you sell.

You get a full inspection that identifies the real problem—not just a sales pitch for the most expensive fix. We look at your foundation, your drainage, your grading, and how water moves around your property during heavy rain.
In Kennett, that matters. The Delaware Valley gets storms that drop inches of rain in a short window, and the clay-heavy soil around here doesn’t drain fast. Your system has to handle that, or you’re going to keep dealing with water. We design around your property and your specific water issues.
You also get interior or exterior waterproofing depending on what makes sense. Interior systems include perimeter drainage, sump pumps, and vapor barriers. Exterior systems involve excavation, membrane installation, and drainage boards that keep water away from the foundation entirely. Both come with a lifetime transferable warranty, so if you sell your home, the next owner is covered too.
We use modern materials—not outdated methods that fail in five years. And we’re licensed, insured, and local. If something needs attention down the road, we’re a phone call away.
It depends on where the water is coming from and how your property is set up. Interior waterproofing handles water that’s already making it to your basement—it captures it at the footer and pumps it out before it floods the floor. Exterior waterproofing stops water before it ever reaches your foundation by sealing the walls and redirecting it away from the house.
If you’re seeing water during heavy rain, have an older home, or notice cracks in your foundation, exterior might be the better long-term fix. If your basement is finished or the grading around your home is solid, interior can be just as effective and less invasive.
We’ll inspect your property and tell you what actually makes sense. Some homes in Kennett need both—especially if the soil stays saturated or the lot doesn’t drain well. We’re not going to sell you more than you need, but we’re also not going to cut corners and leave you with a system that doesn’t work when it rains.
Clay soil and poor drainage. Kennett sits in an area where the ground doesn’t absorb water quickly, so when storms hit, the soil around your foundation gets oversaturated. That creates hydrostatic pressure—basically, water pushing against your basement walls until it finds a way in through cracks, joints, or porous concrete.
Older homes are especially vulnerable because foundation materials break down over time and drainage systems weren’t built to handle today’s weather patterns. If your gutters dump water too close to the house or your yard slopes toward the foundation, that makes it worse.
A failed or undersized sump pump is another common cause. If the pump can’t keep up during heavy rain, water backs up and floods the basement. We see this a lot in Kennett—homeowners don’t realize their pump is struggling until it’s too late. Fixing the problem means addressing the drainage, sealing the foundation, and making sure your sump system can handle the volume.
A properly installed system should last decades. Interior drainage systems and sump pumps are built to run for 20-30 years or more if they’re maintained. Exterior waterproofing membranes and drainage boards are designed to last the life of your home—they don’t degrade the way older tar-based coatings do.
The key is using quality materials and installing them correctly. Cheap systems fail because they use thin membranes, undersized pumps, or drainage stone that clogs over time. We use commercial-grade components and back everything with a lifetime transferable warranty, so you’re covered even if you sell.
Maintenance is minimal. You should test your sump pump a few times a year and keep your gutters clean so water doesn’t overwhelm the system. But the waterproofing itself doesn’t require ongoing work. It’s a one-time fix that protects your home as long as you own it. That’s why we stand behind it with a warranty—we know it’s going to hold up.
Yes. Foundation cracks are one of the main entry points for water, so sealing them is usually part of the waterproofing process. We use methods like epoxy or polyurethane injection for smaller cracks and carbon fiber reinforcement for structural issues. The goal is to stop water and stabilize the wall so the crack doesn’t get worse.
In Kennett, foundation cracks are common because of soil movement and hydrostatic pressure. The clay soil expands when it’s wet and contracts when it dries, which puts constant stress on your foundation. Over time, that creates cracks. If water is getting through, it’s not just a cosmetic issue—it’s a sign that pressure is building and your drainage isn’t working.
We assess every crack during the inspection to determine if it’s structural or just a surface issue. If it’s structural, we’ll reinforce it before waterproofing. If it’s minor, we’ll seal it and make sure your drainage system prevents future pressure buildup. Either way, it gets handled as part of the job—not as an add-on you didn’t see coming.
It depends on the size of your basement, the severity of the water problem, and whether you need interior, exterior, or both. Interior systems typically range from a few thousand dollars to around ten thousand for a full perimeter setup with a sump pump. Exterior waterproofing costs more because it involves excavation, but it’s often the most effective long-term solution.
Every home is different. A small basement with minor seepage costs less than a large finished basement that floods during every storm. If your foundation has structural cracks or your drainage system needs a complete overhaul, that adds to the scope.
We give you a clear estimate after the inspection—no surprises, no pressure. You’ll know exactly what the job involves and what it costs before we start. And because we offer a lifetime transferable warranty, you’re not paying for a temporary fix. You’re investing in a system that protects your home and adds value if you ever sell. That’s worth more than going with the cheapest option that fails in five years.
If your basement has ever had water, or if you’re in an area like Kennett where soil and weather create risk, it’s worth considering. Waiting until you have a flood means you’re dealing with damage, mold, and emergency repairs instead of prevention. Waterproofing before a problem starts saves you money and stress.
Basements don’t usually flood without warning. You’ll see signs—damp spots, musty smells, efflorescence on the walls, or minor seepage after heavy rain. Those are early indicators that water is finding its way in, even if it’s not pooling on the floor yet. Addressing it now prevents bigger issues later.
Waterproofing also protects your home value. Buyers notice water damage, and it’s one of the biggest red flags during inspections. A dry basement with a transferable warranty is a selling point. If you’re planning to stay in your home long-term, it gives you peace of mind. If you’re thinking about selling, it makes your property more attractive and easier to close.
