You stop worrying every time rain hits. No more grabbing the shop-vac at midnight. No more wondering if that crack is getting worse or if the next storm will flood your basement again.
A properly waterproofed foundation means your basement stays dry, your air stays clean, and your home’s value stays protected. You’re not dealing with mold growth, musty smells, or the constant stress of water damage. Your foundation walls stay intact instead of bowing or cracking under pressure.
This is what foundation waterproofing in Audubon, PA should do—give you a basement you can actually use and a foundation that lasts. When water can’t get in, everything else gets easier.
Del Val Basement Waterproofing is a family-run company that’s spent over 15 years protecting homes across Montgomery County. We’re based in Plymouth Meeting, which means we know exactly what Audubon foundations deal with—older neighborhoods with aging brick and stone, Pennsylvania’s brutal freeze-thaw cycles, and spring storms that dump water faster than the ground can handle it.
We’re not the biggest waterproofing company. We’re the one that shows up, does the work right, and backs it with a lifetime transferable warranty. You get the expertise of a company that’s seen every foundation problem this area throws at us, without the corporate runaround.
We start with a free inspection of your foundation. We’re looking at where water’s getting in, what’s causing the pressure, and what your foundation actually needs—not what we want to sell you.
If you need exterior foundation waterproofing in Audubon, PA, we excavate around your foundation walls, apply a waterproof membrane, and install proper drainage to redirect water away from your home. If interior work makes more sense, we install our Sub Floor Pressure Relief System—a proven alternative to outdated French drains that structural engineers actually recommend.
We handle foundation leak repair services in Audubon, PA by sealing cracks, installing sump pumps where needed, and making sure water has nowhere to go but away from your foundation. You can stay in your house while we work. Most jobs wrap up in a few days, and when we’re done, your basement foundation waterproofing system is built to last decades.

You get a complete assessment of your foundation’s condition and a detailed plan before any work starts. We’re not guessing—we’re identifying exactly where water’s coming from and how to prevent foundation water damage in Audubon, PA permanently.
Our foundation waterproofing services in Audubon, PA include both interior and exterior solutions. Exterior work means excavation, membrane application, and drainage installation. Interior work means our Sub Floor Pressure Relief System, sump pump installation, and crack sealing. Every job includes proper grading recommendations and downspout adjustments if needed.
Audubon’s older homes face unique challenges. Many foundations here were built with materials that weren’t designed for the water pressure Pennsylvania’s climate creates. Between winter freeze-thaw cycles and spring storms that can drop a month’s rain in two days, your foundation takes a beating. Our foundation wall waterproofing systems are built specifically to handle what this area dishes out.
Everything we install comes with a lifetime transferable warranty. If you sell your house, the warranty goes with it—which means better resale value and one less thing buyers worry about.
Most basement foundation waterproofing projects in Audubon, PA run between $3,000 and $10,000, depending on what your foundation needs. Exterior foundation waterproofing costs more than interior work because of excavation, but it also addresses the problem at the source.
Your actual cost depends on how much of your foundation needs attention, whether you need interior or exterior work (or both), and what kind of drainage system makes sense for your property. A small crack repair might cost a few hundred dollars. A full perimeter exterior waterproofing job with drainage will be closer to the higher end.
We give you a free estimate after inspecting your foundation. You’ll know exactly what the work costs before we start, and there won’t be surprise charges later. We’re not the cheapest option in Montgomery County, but we’re the one that does it right the first time and backs it with a lifetime warranty.
Exterior foundation waterproofing in Audubon, PA stops water before it reaches your foundation walls. We excavate around your foundation, apply a waterproof membrane directly to the exterior walls, and install drainage systems to redirect water away from your home. It’s more invasive and costs more, but it’s the most effective way to prevent foundation water damage in Audubon, PA.
Interior waterproofing manages water that’s already getting through. Our Sub Floor Pressure Relief System relieves hydrostatic pressure under your basement floor and channels water to a sump pump, which pumps it out and away from your foundation. It’s less disruptive, costs less, and works well for homes where exterior excavation isn’t practical.
Sometimes you need both. If your foundation walls are leaking and you’re also dealing with floor seepage, we’ll recommend a combination approach. The goal is to keep your basement dry without doing more work than necessary.
A properly installed foundation waterproofing system should last for the life of your home. Our Sub Floor Pressure Relief Systems can go decades without maintenance. Exterior waterproofing membranes are designed to last 50+ years when installed correctly.
The key is doing it right from the start. Cheap materials fail. Shortcuts create problems. We use commercial-grade membranes for exterior work and structural engineer-recommended systems for interior drainage. Everything we install is built to handle Pennsylvania’s climate—freeze-thaw cycles, heavy spring rains, and the constant water pressure Audubon foundations deal with.
That’s why we back our work with a lifetime transferable warranty. We’re not expecting callbacks. We’re expecting your foundation to stay dry for as long as you own your home, and for the next owner after that.
Yes, if it’s done right. Foundation waterproofing services in Audubon, PA are specifically designed to prevent basement flooding by stopping water at the source and redirecting it away from your foundation.
If your basement floods every time it rains, water is either coming through your foundation walls, up through the floor, or both. Exterior foundation waterproofing stops wall leaks by creating a barrier water can’t penetrate. Interior systems like our Sub Floor Pressure Relief System handle water pressure under your basement floor and pump it out before it can flood your space.
We also look at what’s happening outside—downspouts dumping water next to your foundation, poor grading, or drainage issues that send water straight toward your house. Foundation leak repair services in Audubon, PA aren’t just about sealing cracks. They’re about controlling where water goes so it never reaches your basement in the first place.
Yes. Most foundation waterproofing work in Audubon, PA doesn’t require you to move out. Interior work happens in your basement, and exterior work happens outside. You’ll hear equipment and see our crew, but your daily routine doesn’t stop.
If we’re doing exterior excavation, you’ll want to keep kids and pets away from the work area. We’ll need access to the perimeter of your home, which might mean moving some landscaping or outdoor furniture temporarily. Interior work is even less disruptive—we’re working in your basement, not your living space.
Most jobs finish in a few days. Smaller foundation leak repair services might take a day or two. Full perimeter exterior waterproofing takes longer, usually three to five days depending on your home’s size and what we find once we start digging. We’ll give you a timeline upfront so you know what to expect.
Water stains on your basement walls or floor are the most obvious sign. If you see white chalky deposits (efflorescence) on your foundation walls, water is seeping through and leaving mineral deposits behind. Cracks in your foundation walls, especially horizontal cracks or cracks that are getting wider, mean water pressure is pushing against your foundation.
Musty smells in your basement indicate moisture problems even if you don’t see standing water. Mold or mildew growth on walls, floors, or stored items means humidity levels are too high—usually because water is getting in somewhere. If your basement feels damp or humid even when it hasn’t rained, your foundation isn’t keeping moisture out.
You might also notice bowing or bulging foundation walls, which happens when water pressure builds up outside and pushes against your foundation. This is serious—it means your foundation’s structural integrity is at risk. The sooner you address foundation water leakage repair in Audubon, PA, the less damage you’ll deal with and the less the fix will cost.
