You stop checking the basement every time it rains. That knot in your stomach when the forecast shows storms? Gone.
Your insulation stays dry, which means your heating and cooling systems aren’t working overtime. Most homeowners see energy costs drop 10-15% once moisture is controlled. That’s real money back in your pocket every month.
The musty smell disappears. Not covered up—gone. Because 40% of the air you breathe upstairs starts in your basement, controlling moisture down there means healthier air throughout your entire home. No more wondering if that smell is affecting your family’s health.
Your home value holds. A dry basement protects your investment and makes your property easier to sell when the time comes. Buyers walk away from wet basements, but they’ll pay more for one that’s professionally waterproofed with a transferable warranty.
We’re a family-run waterproofing contractor serving London Grove, PA and Chester County for over 15 years. We’re not a national franchise with rotating crews—we’re local, and we’ve seen what Pennsylvania’s clay-heavy soil and unpredictable weather do to foundations.
London Grove sits in an area where spring snowmelt and heavy rainfall create serious hydrostatic pressure against your foundation. We understand how water moves through this region’s soil, and we know which solutions actually work long-term versus which ones just push the problem down the road.
You get the experience of a larger company with the responsiveness of a local business. We answer when you call, show up when we say we will, and we don’t disappear after the job is done.
First, we inspect your basement to find where water is getting in and why. Most water problems come from hydrostatic pressure, poor grading, or failed drainage systems. We look for all of it—the obvious signs and the subtle ones most homeowners miss.
Then we explain what we found in plain language. No jargon, no upselling. You’ll understand what’s happening, what needs to be fixed, and what it costs before any work starts.
Once you approve, we install the right system for your specific situation. That might mean interior drainage with a sump pump, exterior waterproofing, foundation crack repair, or a combination. Every home is different, and cookie-cutter solutions don’t work.
After installation, we test everything to make sure water has nowhere to go except away from your foundation. Then we clean up, walk you through what we did, and hand you a lifetime transferable warranty. If water ever comes back, so do we.

You get a customized system designed for your home’s specific water problem. We handle interior waterproofing with drainage systems and sump pumps, exterior waterproofing to stop water before it reaches your foundation, foundation crack repair, crawl space encapsulation, and mold remediation if moisture has already caused damage.
In London Grove, PA, where clay-rich soil holds water and creates constant pressure against foundations, the right waterproofing system isn’t optional—it’s necessary. Pennsylvania gets 40-50 inches of rain annually, and when you add spring snowmelt to the mix, that’s a lot of water trying to find its way into your basement.
Every job comes with a lifetime transferable warranty. That means if you sell your home, the warranty transfers to the new owner. It’s protection that adds value and gives buyers confidence.
You also get honest pricing upfront. The average basement waterproofing project in this area runs between $3,000-$10,000 depending on the scope of work. We don’t play games with pricing or pressure you into decisions. You get a clear estimate, and that’s what you pay.
If you’re seeing water more than once, DIY fixes won’t solve it. Painting on sealant or running a dehumidifier treats symptoms, not causes.
Water doesn’t show up by accident. Once it finds a way into your basement, it’s marked that route. Hydrostatic pressure—the force of water-saturated soil pushing against your foundation—doesn’t quit. It works 24/7, and it only gets stronger when it rains or snow melts.
A professional waterproofing contractor identifies why water is getting in, not just where. That might be failed drainage, foundation cracks, poor grading, or a combination. Fixing the root cause requires the right equipment, materials, and experience. If you’re dealing with recurring water, you need someone who can diagnose the real problem and install a system that actually stops it for good.
Interior waterproofing manages water that’s already made it to your foundation. We install drainage systems along the basement floor perimeter that capture water and direct it to a sump pump, which then pumps it away from your home. This approach works well when exterior access is limited or when you need a solution that doesn’t require excavation.
Exterior waterproofing stops water before it ever reaches your foundation walls. We excavate around the foundation, apply waterproof membrane or coating, install drainage systems, and ensure proper grading. It’s more invasive and typically costs more, but it’s also the most comprehensive solution.
Which one you need depends on your specific situation. Some homes need both. In London Grove, PA, where clay soil retains moisture and creates persistent pressure, exterior waterproofing often makes sense for older homes or properties with chronic water problems. We assess your home and recommend the approach that actually solves your problem without overselling.
A professionally installed waterproofing system lasts decades when done correctly. That’s why we back our work with a lifetime transferable warranty.
The longevity depends on the quality of materials and installation. Cheap systems fail within a few years. Proper systems—using commercial-grade sump pumps, durable drainage materials, and correctly applied membranes—keep working for the life of your home.
Your sump pump is the one component that needs occasional attention. We recommend testing it twice a year and replacing the pump every 7-10 years depending on how hard it works. That’s normal maintenance, not system failure. Everything else—the drainage channels, waterproof barriers, and structural repairs—should perform without issue for decades. If something does go wrong, our warranty means we come back and make it right at no cost to you.
Yes, because that smell is moisture. Waterproofing eliminates the source, which means mold can’t grow and the smell disappears.
Mold needs moisture to survive. It starts growing within 24-48 hours of water intrusion, and once it’s established, it releases spores that create that musty, earthy smell. Covering it up with dehumidifiers or air fresheners doesn’t solve anything—you’re just masking the problem while mold continues spreading.
When we waterproof your basement, we cut off mold’s water supply. No moisture means no mold growth. If mold is already present, we handle remediation as part of the process, removing contaminated materials and treating affected areas. Then the waterproofing system keeps new moisture out so mold can’t return. This matters for your health—mold triggers allergies, worsens asthma, and causes respiratory issues, especially in children and older adults. A dry basement means cleaner air throughout your entire home.
Most basement waterproofing projects in London Grove, PA run between $3,000-$10,000. The actual cost depends on the size of your basement, the severity of the water problem, and which solutions your home needs.
A basic interior drainage system with a sump pump typically starts around $3,000-$5,000. Exterior waterproofing costs more—usually $8,000-$15,000—because it requires excavation and more labor. Foundation crack repair, crawl space encapsulation, and mold remediation add to the total depending on what your specific situation requires.
Here’s what matters: the cheapest option isn’t always the best value. A system that fails in three years costs you more in the long run than one that works for decades. We give you transparent pricing upfront and explain exactly what you’re paying for. No surprises, no pressure tactics. You’re making a decision about protecting your home’s foundation and your family’s health—you deserve honest numbers and real solutions, not a sales pitch.
We come back and fix it at no cost to you. Every waterproofing job we complete comes with a lifetime transferable warranty.
That warranty isn’t just paperwork—it’s our commitment that the system we install will keep your basement dry. If water finds a way in, we return to diagnose why and make whatever repairs are necessary to stop it. You don’t pay for the service call, the labor, or the materials.
This warranty also transfers if you sell your home, which adds real value for buyers. They’re getting a basement with professional waterproofing and the peace of mind that comes with lifetime coverage. Most waterproofing companies in the area offer warranties, but not all are transferable and not all are backed by a local, family-owned business that’s been serving Chester County for over 15 years. We’re not going anywhere, and neither is our commitment to keeping your basement dry.
