You stop worrying every time it rains. Your basement doesn’t smell like mildew, and you’re not running downstairs with a Shop-Vac at 2 a.m. anymore.
The space you’ve been avoiding becomes usable again. You can store what matters without wondering if it’ll get ruined. When you eventually sell, you won’t be explaining away water stains or dealing with lowball offers because buyers spotted moisture.
North Coventry sits in an area where clay-heavy soil doesn’t drain well, and Pennsylvania’s unpredictable weather—spring downpours, rapid snowmelt, freeze-thaw cycles—puts constant pressure on your foundation. That’s not going away. But with the right waterproofing system, the water doesn’t get inside. It gets redirected, managed, and kept where it belongs.
Your home’s value stays intact. Your family’s health isn’t compromised by mold or poor air quality. And you get peace of mind that doesn’t depend on the forecast.
We’re a family-run company based in Plymouth Meeting, serving North Coventry and the greater Philadelphia area for over 15 years. We’re not a national franchise with rotating crews. You’re working with people who know Pennsylvania soil, Pennsylvania weather, and what actually works here.
We specialize in basement waterproofing, foundation repair, mold remediation, and sump pump systems. Every job comes with a lifetime transferable warranty, which means if you sell your home, the protection goes with it. That’s not common in this industry, and we do it because we stand behind the work.
You won’t get upsold on things you don’t need. We identify the root cause, explain what’s happening, and fix it right the first time. North Coventry homeowners deal with high water tables, shifting soil, and seasonal flooding risks—we’ve seen it all, and we know how to handle it without the runaround.
First, we come out and assess your basement. We’re looking at where the water’s coming from, how your foundation is holding up, and what’s causing the pressure. That could be poor drainage, hydrostatic pressure from saturated soil, or cracks that have gone unnoticed for years.
Once we know what’s going on, we walk you through the fix. Most jobs involve installing a sub-floor pressure relief system—a more reliable alternative to outdated French drains—along with a sump pump if needed. We might also seal cracks, install vapor barriers, or address exterior drainage issues depending on your situation.
The work itself is straightforward. You can stay in your home while we’re there. There’s some noise and a bit of dust, but it’s manageable. We’re not tearing your house apart. Once the system’s in, it works quietly in the background, redirecting water away from your foundation and keeping your basement dry.
After we’re done, you get documentation, warranty details, and a system that’s designed to last as long as you own the home. No maintenance plans. No annual checkups. Just a basement that works the way it should.

Every waterproofing job is customized based on what your home actually needs, but most projects include a sub-floor pressure relief system, sump pump installation or replacement, foundation crack sealing, and interior or exterior drainage work depending on severity.
In North Coventry, we’re often dealing with homes on properties where water pools near the foundation due to poor grading or clay soil that doesn’t absorb moisture. We address that by redirecting water before it ever reaches your walls. If there’s already damage—cracks, mold, compromised structural integrity—we handle that too.
You also get a lifetime transferable warranty on the work. That’s not a gimmick. It means the system is built to last, and if something ever goes wrong, we come back and make it right. It also adds value when you sell, because buyers know the basement is protected.
We’re not the cheapest option, and that’s intentional. You’re paying for a system that works, a team that knows what they’re doing, and a warranty that actually means something. Cheaper fixes fail. Then you’re paying twice—once for the bad job, and again for the real one.
Gutters help, but they’re not a waterproofing system. If your gutters are clogged or poorly positioned, water dumps right next to your foundation and seeps in. Fixing that might reduce some moisture, but it won’t stop hydrostatic pressure or groundwater from pushing through your walls.
If you’re seeing water after heavy rain, damp spots that won’t go away, or musty smells even when it’s dry outside, gutters aren’t going to solve it. You need a system that manages water at the foundation level—something that intercepts it before it gets inside and redirects it away from your home.
A good waterproofing contractor will tell you if gutters are part of the problem. We’re not here to sell you a full system if all you need is better drainage. But if water’s already getting in, you’re past the point where gutters alone will fix it.
Exterior waterproofing means excavating around your foundation, sealing the walls from the outside, and installing drainage systems at the footing level. It’s the most thorough option, but it’s also the most expensive and disruptive. You’re tearing up landscaping, driveways, and anything else in the way.
Interior waterproofing works from inside your basement. We install a sub-floor drainage system that captures water before it surfaces, then pump it out through a sump system. It’s less invasive, more affordable, and just as effective for most homes in North Coventry where the issue is groundwater or hydrostatic pressure.
Exterior makes sense if your foundation walls are severely compromised or if you’re dealing with structural issues that need outside access. Interior makes sense for everything else. We’ll tell you which one your home actually needs based on what we see during the assessment, not based on what costs more.
Most interior waterproofing jobs take two to four days depending on the size of your basement and the scope of work. Exterior jobs take longer—usually a week or more—because of excavation and backfill time.
You can absolutely stay in your house during the work. There’s noise from jackhammering if we’re installing a sub-floor system, and there’s dust even though we do our best to contain it. But it’s not unlivable. Families do it all the time.
We work during normal business hours, clean up at the end of each day, and keep disruption to a minimum. You won’t have strangers wandering through your house at odd hours, and you won’t come home to a disaster zone. Once we’re done, the system’s in place and you’re back to normal—except now your basement stays dry.
Waterproofing stops the moisture that causes mold, but it doesn’t remove mold that’s already there. If you’ve got visible mold growth, that needs to be remediated separately. We handle both—waterproofing and mold remediation—so it can be done at the same time if needed.
Mold spreads through your HVAC system and affects air quality throughout your home, not just the basement. It’s a health risk, especially for anyone with asthma or allergies. The longer it sits, the worse it gets and the more expensive it becomes to remove.
Once the waterproofing system is in and the mold is gone, the problem doesn’t come back. No moisture means no mold. But you have to address both sides of it—stopping the water and cleaning up what’s already growing. Waterproofing alone won’t make existing mold disappear.
That’s what the lifetime transferable warranty covers. If something goes wrong with the system we installed, we come back and fix it at no cost to you. That includes the drainage system, the sump pump, and any sealing work we did on your foundation.
The warranty transfers if you sell your home, which is a selling point for buyers. They know the basement is protected and that if anything ever happens, it’s covered. Not many waterproofing contractors offer that, and the ones who do are usually the ones confident their work will last.
We’re not in the business of installing systems that fail. Our reputation depends on jobs that hold up over time. But if something does happen—a pump quits, a drain clogs, whatever—you’re not stuck paying for repairs or dealing with water damage while you figure it out. You call us, and we handle it.
North Coventry sits in Chester County, where soil conditions and weather patterns create the perfect storm for basement moisture. The soil here is heavy in clay, which doesn’t drain well. When it rains, water doesn’t absorb—it pools. When it freezes, the ground can’t absorb anything, so spring thaw dumps all that water right into the soil around your foundation.
Pennsylvania also gets hit with unpredictable weather. Heavy spring rains, summer downpours, rapid snowmelt in winter—all of it puts pressure on your foundation. Add in an aging housing stock where homes were built before modern waterproofing standards, and you’ve got a lot of basements that were never designed to handle this kind of moisture.
The water table in parts of Pennsylvania is high, meaning the soil around your home is often saturated. That creates hydrostatic pressure—water pushing against your foundation walls from the outside. Over time, it finds cracks, seams, and weak points. That’s why so many homes here deal with recurring water issues. It’s not bad luck. It’s geology and climate, and it’s not going away without a real system in place.
