You stop running downstairs every time it rains. You’re not setting alarms for 2 a.m. storm checks or keeping shop-vacs on standby. Your basement smells normal again—no mildew, no mustiness, no wondering if mold is growing behind the walls.
A dry basement means you can actually use that space. Store things without worrying they’ll get ruined. Finish it someday if you want. Most importantly, you’re protecting your home’s foundation from the kind of damage that costs tens of thousands to repair later.
Ardmore’s clay-heavy soil and the clay bowl effect around older Main Line homes make water intrusion a real problem here. When your waterproofing system is designed for these specific conditions, you get results that last—not temporary fixes that fail after the next heavy rain.
We’ve been waterproofing basements across the Delaware Valley since 2007. We’re a family-owned company that serves Montgomery County, Delaware County, Chester County, and the surrounding Philadelphia area with one focus: keeping your basement dry for good.
We know Ardmore’s older homes. We’ve worked on foundations built decades ago that are now dealing with hydrostatic pressure, poor drainage, and soil that holds water like a sponge. Every system we install is backed by a lifetime transferable warranty, so you’re covered—and if you sell, the next owner is too.
You won’t get a hard sell or a crew that disappears after the deposit clears. You’ll get straight answers, a clear plan, and work that’s designed to last as long as you own your home.
First, we come out and assess what’s actually causing the water problem. Is it hydrostatic pressure pushing water through your foundation? Poor exterior drainage? Cracks in the walls? We don’t guess—we diagnose.
Then we design a system that fits your home. For most Ardmore basements, that means installing our Sub Floor Pressure Relief System—a proven alternative to old French drains that actually relieves the pressure causing water to seep in. We may also recommend sump pump installation, exterior drainage work, or foundation crack repair depending on what your home needs.
The installation itself is straightforward. You can stay in your house while we work—it’s not invasive, and most jobs wrap up in a few days. Once it’s done, we test the system, walk you through how it works, and hand you a lifetime warranty. After that, your basement stays dry—even during Pennsylvania’s heaviest storms.

Every waterproofing job is different, but most include interior drainage systems designed to capture water before it floods your basement. We install perimeter drains, sump pumps, and vapor barriers where needed. If your foundation has cracks, we seal them properly—not with temporary patches that fail in six months.
For homes dealing with exterior water problems, we handle that too. Exterior waterproofing, drainage correction, and downspout extensions all help keep water away from your foundation in the first place. Ardmore’s clay soil doesn’t drain well on its own, so managing water at the source makes a huge difference.
If your crawl space is damp or your basement already has mold, we address that as part of the process. Mold inspection, remediation, and crawl space encapsulation are all services we provide. The goal isn’t just to stop the water—it’s to make sure your home is safe, dry, and protected long-term.
Most homeowners in Ardmore spend between $4,000 and $8,000 on basement waterproofing, depending on the size of the space and the severity of the water problem. If you need exterior excavation or extensive foundation repair, costs can go higher—sometimes up to $15,000 for complex jobs.
The price depends on what your home actually needs. A straightforward interior drainage system with a sump pump costs less than a full perimeter waterproofing job with exterior work. We give you a clear estimate upfront, so there are no surprises.
What matters more than the initial cost is whether the system actually works. Cheap fixes fail, and then you’re paying again in a year or two—plus dealing with water damage in between. Our systems are designed to last for decades, and they’re backed by a lifetime transferable warranty.
Ardmore’s clay-heavy soil is a big part of the problem. Clay doesn’t drain well, so when it rains, water sits around your foundation instead of flowing away. Over time, that creates hydrostatic pressure—basically, water pushing against your basement walls until it finds a way in through cracks, seams, or porous concrete.
The clay bowl effect makes it worse. When your home was built, the soil around the foundation was excavated and then backfilled. If that backfill wasn’t compacted properly, it creates a bowl that collects water right where you don’t want it—against your foundation walls.
Older Main Line homes also deal with aging drainage systems, cracked foundations, and gutters that dump water too close to the house. All of these issues compound over time, which is why basements that were dry for years suddenly start leaking.
A properly installed system lasts for decades—often for the entire life of your home. Our Sub Floor Pressure Relief System is designed to work without ongoing maintenance, and we back it with a lifetime transferable warranty because we know it holds up.
The key is using the right system for your home’s specific conditions. Cheap fixes like surface sealants or DIY crack fillers might last a year or two before they fail. Interior drainage systems with sump pumps, on the other hand, are built to handle Pennsylvania’s heavy rains and freeze-thaw cycles without breaking down.
If you maintain your sump pump (which just means checking it once or twice a year), the system keeps working. You’re not reapplying coatings or resealing cracks every few years. It’s a one-time fix that actually solves the problem.
Yes. Most waterproofing jobs are non-invasive, and you can stay in your home while we work. We’re typically working in the basement or outside around the foundation, so your daily routine doesn’t get disrupted.
The process does involve some noise—jackhammering for interior drainage systems, excavation equipment for exterior work—but it’s not an all-day, every-day thing. Most jobs take a few days to a week, depending on the scope. We keep the work area contained, clean up as we go, and make sure you’re not dealing with a construction zone for weeks on end.
If you have specific concerns—pets, kids, work-from-home schedules—we work around them. The goal is to fix your basement without making your life harder in the process.
Interior waterproofing manages water that’s already made it to your foundation. We install drainage systems inside your basement that capture water and direct it to a sump pump, which then pumps it away from your home. It’s effective, less expensive than exterior work, and doesn’t require digging up your yard.
Exterior waterproofing stops water before it reaches your foundation. This involves excavating around the outside of your home, applying waterproof coatings or membranes to the foundation walls, and installing drainage systems that redirect water away. It’s more invasive and costs more, but it’s sometimes necessary for severe water problems or homes with significant foundation damage.
Most Ardmore homes do fine with interior systems, especially when combined with proper grading and drainage corrections outside. We assess your specific situation and recommend what actually makes sense—not what costs the most.
Yes, if you eliminate the moisture that’s feeding the mold. Mold needs water to grow, so once your basement stays consistently dry, mold can’t thrive. If you already have mold, we handle remediation as part of the waterproofing process—removing the existing growth and treating affected areas before sealing everything up.
A dry basement also improves your home’s air quality. Mold spores circulate through your HVAC system, which means a moldy basement affects the air you’re breathing upstairs too. Fixing the water problem fixes the air problem.
Keep in mind that waterproofing alone won’t help if you have other moisture sources like poor ventilation or humidity. We look at the full picture and recommend dehumidifiers or ventilation improvements if needed. The goal is a basement that stays dry and healthy year-round.
