You’re not just fixing a wet floor. You’re protecting two-thirds of your wealth—because that’s how much of your net worth is tied up in your home.
When your basement stays dry, you avoid the $6,000+ repair bills that come with water damage. You stop mold before it starts affecting your family’s breathing. You keep your foundation from cracking under hydrostatic pressure.
You also get your space back. That basement can actually be used for storage, a workspace, or finished living area—instead of being the room you avoid because it smells like mildew.
A waterproofing company in Blue Bell, PA that knows what they’re doing doesn’t just patch the problem. We engineer a system that keeps water out for good, so you’re not calling someone back in two years when the next storm hits.
Del Val Basement Waterproofing is a family-run waterproofing contractor in Blue Bell, PA. We started in this industry in 2007 because we saw too many homeowners getting sold systems that didn’t work—or paying twice for repairs that should’ve been done right the first time.
Blue Bell sits in Montgomery County, where more than 70% of homes were built before 1980. Older construction means older foundations, outdated drainage, and basements that weren’t designed for the kind of weather we’re getting now. The Northeast has seen a 55% increase in heavy precipitation, and your basement feels it.
We back every job with a lifetime transferable warranty. That means if you sell your house, the new owner is covered too. It’s not a gimmick—it’s how we’ve built our reputation for over 15 years.
First, we come out and inspect your basement for free. We’re looking at where the water’s coming from—whether it’s surface runoff, groundwater pressure, or cracks in your foundation. We don’t guess.
Then we explain your options. Interior waterproofing uses sealants and drainage systems to manage water that’s already getting in—it’s the budget-friendly route. Exterior waterproofing involves excavating around your foundation, applying a waterproof membrane, and improving drainage at the source. It costs more, but it’s the most thorough fix.
We recommend what makes sense for your situation. If you’ve got hydrostatic pressure pushing water through your basement floor, we’ll talk about our Sub Floor Pressure Relief System—a proven alternative to outdated French drains that structural engineers actually recommend.
Once you approve the plan, we get to work. Most jobs don’t require you to move out. You’ll hear some noise and see some dust, but you can stay in your house. When we’re done, we test the system and walk you through the warranty.

You get a system designed for Blue Bell’s specific conditions. Subsurface groundwater is a major issue here because of how the water table fluctuates. When groundwater rises above your basement floor level, your basement acts like a boat trying not to sink. That’s why we focus on pressure relief and proper drainage—not just sealing cracks and hoping for the best.
You also get a company that shows up when we say we will. We know 58% of homeowners want their sump pump repaired within two days, and another 26% want it done within two weeks. Most of these calls are emergencies, and we treat them that way.
We install sump pumps, repair foundation cracks, waterproof walls, and design full perimeter drainage systems. Every job comes with that lifetime transferable warranty, which means you’re covered as long as you own the home—and so is the next owner if you sell.
We’re a company to fix wet basement issues in Blue Bell, PA that’s been doing it long enough to know what works. We’re not experimenting on your house.
It depends on what’s causing the water and how you want to fix it. Interior waterproofing—sealants, drainage systems, sump pumps—typically runs less than exterior work because there’s no excavation involved. Exterior waterproofing costs more because we’re digging around your foundation, applying a membrane, and regrading drainage. But it’s also the most permanent solution.
For a basement water damage repair company in Blue Bell, PA to give you an accurate number, we need to see your basement. Every foundation is different. We offer free inspections, and we’ll explain what each option costs and why.
Most homeowners spend anywhere from a few thousand to over ten thousand depending on the scope. That sounds like a lot until you compare it to the $6,000+ you’ll pay every time your basement floods—and the fact that most insurance policies won’t cover it because it’s considered preventable maintenance.
If it’s done right, yes. But “done right” means addressing the actual source of the water—not just slapping sealant on the walls and calling it a day.
Water gets into basements three ways: through cracks in the foundation, through hydrostatic pressure in the floor, or from poor drainage around the house. A good waterproofing contractor in Blue Bell, PA will figure out which one (or combination) you’re dealing with and build a system that handles it.
Interior systems manage water that’s already coming in by channeling it to a sump pump and out of your house. Exterior systems stop water before it ever reaches your foundation. Both work—but exterior is more thorough if you’ve got serious groundwater issues, which a lot of Blue Bell homes do because of the water table and older construction.
We’ve been doing this since 2007, and we back it with a lifetime warranty. That’s how confident we are that it works.
Most interior jobs take one to three days depending on the size of your basement and what we’re installing. If we’re putting in a perimeter drainage system and a sump pump, that’s usually a two-day job. Foundation crack repair can be done in a few hours if it’s straightforward.
Exterior waterproofing takes longer—usually three to five days—because we’re excavating around your foundation, applying the membrane, installing drainage, and backfilling. Weather can affect the timeline, but we work efficiently and keep you updated.
You don’t need to move out. The work is non-invasive enough that you can stay in your house. There will be noise and some dust, especially with interior drainage work, but it’s manageable. We clean up when we’re done, and we test everything before we leave to make sure it’s working the way it should.
Interior waterproofing manages water after it’s already trying to get in. We install drainage systems along the perimeter of your basement floor, seal cracks, and use sump pumps to push the water back out. It’s effective, less expensive, and doesn’t require digging up your yard.
Exterior waterproofing stops water before it reaches your foundation. We excavate around the outside of your house, apply a waterproof membrane to the foundation walls, install drainage systems, and regrade the soil so water flows away from your home. It’s more thorough, more expensive, and the best option if you’ve got serious groundwater pressure or foundation issues.
For homes in Blue Bell, PA with basement moisture problems tied to an older foundation or high water table, exterior waterproofing is often the smarter long-term investment. But interior systems work great for a lot of situations, and they’re a solid choice if your budget is tighter. We’ll walk you through both and recommend what makes sense for your house.
In most cases, yes. A sump pump is your last line of defense. Even with a great drainage system, water still needs somewhere to go—and a sump pump is what pushes it out of your house and away from your foundation.
If you’ve got groundwater pressure, a high water table, or you’re in an area that floods during heavy rain (which Blue Bell sees more of every year), a sump pump isn’t optional. It’s essential. About 58% of homeowners want their sump pump fixed within two days when it breaks, because they know what happens if it’s not working when the next storm hits.
We install sump pumps as part of most waterproofing systems, and we make sure they’re reliable. Battery backups are a good idea too, because if your power goes out during a storm, you still need that pump running. It’s one of those things you don’t think about until you need it—and then you’re really glad it’s there.
If you’re seeing water pooling on your floor after it rains, that’s obvious. But a lot of basement water problems start quieter. You might notice a musty smell, white chalky residue on your walls (that’s efflorescence from moisture), or damp spots that never fully dry.
Cracks in your foundation walls or floor are another sign, especially if they’re getting wider or if you see water seeping through. Mold or mildew growth means moisture is present even if you don’t see standing water. And if your basement feels humid or your dehumidifier runs constantly, that’s your house telling you something’s wrong.
Blue Bell homes—especially older ones—are at higher risk because of how they were built and how the water table behaves in Montgomery County. About 98% of basements will experience some form of water damage during their lifespan. The question isn’t if, it’s when. If you’re noticing any of these signs, it’s worth getting a free inspection from a residential waterproofing company in Blue Bell, PA before it turns into a bigger (and more expensive) problem.
