Hear from Our Customers
You’re not dealing with a damp basement anymore. You’re not worrying about the next heavy rain. You’re not calling someone back to fix what should’ve worked the first time.
Your basement stays dry through spring snowmelt and summer downpours. Your foundation isn’t shifting or cracking from hydrostatic pressure. Your air quality improves because mold doesn’t have the moisture it needs to grow.
You can actually use that space. Store things without worrying they’ll get ruined. Finish it if you want. Or just know it’s protected.
That’s what proper basement waterproofing in Cheltenham, PA does. It removes the problem so you can stop thinking about it.
We’re family-run, which means you’re not getting a different crew every time or a call center when something needs attention. We’ve been handling foundation and waterproofing work across Montgomery County since we started, and about half our jobs are fixing systems other companies installed that failed.
Cheltenham gets hit with the same weather patterns that flood basements across the Greater Philadelphia area—heavy spring rains, flash flooding, soil that expands and contracts with the seasons. We’ve seen what works here and what doesn’t.
We’re not the biggest name you’ll find. But we’re the ones structural engineers recommend, and we back our work with a lifetime transferable warranty.
First, we come out and inspect your basement at no cost. We’re looking at where water’s getting in, what’s causing it, and what your foundation actually needs—not what’s easiest to sell you.
Then we walk you through the fix. Most jobs involve installing a sub-floor pressure relief system, which handles hydrostatic pressure better than old French drains. We’re also looking at your sump pump situation, any cracks in your foundation walls, and whether exterior waterproofing makes sense for your property.
The work itself is non-invasive. You can stay in your house while we’re working. We’re not tearing up your entire basement or making you move out for a week.
Once it’s done, it’s done. The system works passively—you don’t have to think about it. Water gets redirected before it becomes a problem. Your basement stays dry. And if anything ever goes wrong, the warranty covers it.
Ready to get started?
Basement waterproofing in Cheltenham isn’t one-size-fits-all, but most systems include a few core components. You’re getting a sub-floor drainage system that relieves pressure before water can push through your foundation. That’s paired with a sump pump setup that actually works when you need it—not one that clogs or fails during heavy rain.
If you’ve got cracks in your foundation walls, we seal those using methods that hold up in Pennsylvania soil conditions. Some homes need exterior waterproofing, where we excavate around the foundation and apply a waterproof membrane. Others just need interior solutions.
Cheltenham properties deal with a lot of clay-heavy soil that holds water and creates pressure against foundation walls. That’s why drainage solutions matter here—you’re not just blocking water, you’re redirecting it away from your foundation entirely. We also handle crawl space encapsulation if that’s where moisture is getting in.
Every system is built for the specific way water’s affecting your property. Not a generic fix.
Most basement waterproofing projects in Cheltenham run between $3,500 and $7,000, depending on the size of your basement and what’s causing the water problem. If you need exterior waterproofing or significant foundation repair, costs go higher—sometimes into the $10,000 to $15,000 range.
The price depends on whether we’re installing an interior drainage system, fixing foundation cracks, adding exterior waterproofing, or replacing a failed system. Bigger basements cost more. Homes with severe foundation damage cost more.
We give you a free estimate after inspecting your basement, so you know exactly what you’re paying for before any work starts. No surprises, no upselling. Just a clear number based on what your foundation actually needs.
Most interior basement waterproofing jobs take two to four days, depending on the size of your basement and the scope of work. Smaller basements with straightforward drainage needs can be done in a day or two. Larger spaces or homes that need both interior and exterior work take closer to a week.
You can stay in your house during the process. The work is contained to the basement, and we’re not disrupting your whole home. There’s some noise and dust, but it’s manageable.
Exterior waterproofing takes longer because we’re excavating around your foundation. That usually adds a few extra days. But once it’s done, it’s a permanent fix—not something you’ll be calling us back about in a few years.
Yes, when it’s done right. A properly installed basement waterproofing system in Cheltenham keeps water out even during heavy rain and spring flooding. That’s the point—you shouldn’t have to worry about your basement every time it storms.
The system works by managing hydrostatic pressure and redirecting water before it can seep through your foundation walls or floor. Your sump pump removes any water that does make it to the drainage system, and it gets pumped away from your house entirely.
The reason we can back this with a lifetime warranty is because these systems work. We’ve installed them in hundreds of homes across Montgomery County, and they hold up through Pennsylvania’s worst weather. If water’s still getting in after we’re done, something’s wrong—and we’ll fix it.
Hydrostatic pressure is the main culprit. When it rains heavily, water saturates the soil around your foundation and creates pressure against your basement walls. That pressure forces water through any cracks, gaps, or porous areas in your foundation.
Cheltenham sits in an area with clay-heavy soil that doesn’t drain well, so water sticks around longer and builds up more pressure. Add in Pennsylvania’s freeze-thaw cycles, and your foundation expands and contracts throughout the year, which creates cracks over time.
Poor drainage around your home makes it worse. If your gutters dump water right next to your foundation or your yard slopes toward your house, you’re funneling water directly to your basement. Fixing the waterproofing problem means addressing the pressure, the cracks, and the drainage all at once.
Most homes in Cheltenham only need interior waterproofing, which is less invasive and more affordable. Interior systems handle the water after it’s passed through your foundation but before it floods your basement. They work well for typical water seepage and drainage issues.
Exterior waterproofing makes sense if your foundation walls are severely cracked, if you’re dealing with constant water intrusion, or if interior solutions haven’t worked. It involves excavating around your foundation and applying a waterproof membrane directly to the exterior walls. It’s more expensive and takes longer, but it stops water before it even reaches your foundation.
We’ll tell you which one you actually need after inspecting your basement. Some homes need both—interior drainage to manage water and exterior sealing to protect damaged foundation walls. But plenty of basements are fine with just an interior system and proper drainage.
Water in your basement is the obvious sign, but you’ll usually notice smaller issues first. Damp spots on your walls or floor, a musty smell, or visible mold growth all mean moisture is getting in. If your sump pump is running constantly or not kicking on at all, that’s a problem.
Cracks in your foundation walls that are getting wider or new cracks appearing mean your waterproofing isn’t managing hydrostatic pressure. Efflorescence—that white, chalky residue on concrete—shows that water is seeping through and leaving mineral deposits behind.
If your system was installed more than 15 or 20 years ago and you’re starting to see any of these signs, it’s probably time for an inspection. Older systems clog, fail, or just weren’t built to handle the kind of water pressure Cheltenham properties deal with. Half the work we do is replacing systems that stopped working.
