You stop dreading the forecast. That knot in your stomach when rain’s coming? Gone. Your basement stays dry through spring downpours, snowmelt in March, and those surprise storms that seem to find every crack in Glenside’s older homes.
Your family breathes easier—literally. No more musty smell creeping upstairs. No mold hiding behind stored boxes or along foundation walls. Just clean air and a space you can actually use without worrying about what’s growing down there.
Your property value holds. When it’s time to sell, you’re not explaining away water stains or crossing your fingers during inspections. You’re handing over documentation of professional basement waterproofing in Glenside, PA with a warranty that transfers to the next owner. That’s the kind of peace of mind that shows up in offers.
Del Val Basement Waterproofing is a family-run basement waterproofing company that’s been handling foundation and water issues across Glenside, PA and the greater Philadelphia area since we started. We’re not new to Pennsylvania’s clay soil, freeze-thaw cycles, or how water finds its way into older homes around here.
You’re working with people who understand that basement waterproofing in Glenside isn’t just about pumps and drains. It’s about knowing how this area’s weather patterns work, what happens when temperatures swing from 20 to 50 in a week, and why your neighbor three houses down might have zero issues while you’re dealing with standing water every spring.
We back every job with a lifetime transferable warranty because we’re not interested in coming back to patch our own work. You want it done right the first time. So do we.
First, we come look at your basement. Not to sell you the most expensive option—to figure out where water’s getting in and why. Sometimes it’s obvious. Sometimes it takes experience to spot the real problem. We check your foundation walls, floor joints, window wells, and how water’s moving around your property.
Then we explain what needs to happen. Interior waterproofing, exterior work, drainage systems, sump pump installation—whatever your situation actually requires. You get a clear breakdown of the process and the cost. No surprises later.
Once you’re ready to move forward, we schedule the work around your life, not ours. Our crew shows up, does the job, and cleans up after. You’re not left with a mess or half-finished work while we disappear to another site.
After installation, you get documentation of everything we did and your lifetime warranty. Then we wait for the next big storm—because that’s when you’ll really see the difference. Most customers reach out after that first heavy rain to tell us their basement stayed bone dry. That’s the whole point.

Basement waterproofing in Glenside, PA means addressing how water interacts with your specific property. Interior systems handle water that’s already making its way in—we’re talking drainage channels, sump pumps, and vapor barriers that redirect water before it pools on your floor. This works well for homes where exterior access is limited or when you need a solution that doesn’t require tearing up your landscaping.
Exterior waterproofing tackles the problem at the source. We excavate around your foundation, apply waterproof membranes to your basement walls, and install drainage systems that keep water away from your home entirely. It’s more invasive upfront but often the right call for older Glenside homes with foundation issues or persistent seepage.
Crawlspace work matters too. If you’ve got a crawlspace instead of a full basement, moisture control down there affects your whole house. We encapsulate, install vapor barriers, and set up dehumidification systems that stop humidity from rotting floor joists or creating mold problems you won’t see until it’s expensive.
Foundation crack repair is part of the conversation when we’re dealing with structural issues. Pennsylvania’s soil and temperature swings cause settling and cracking. We seal those entry points with methods that flex with your foundation instead of cracking again next winter.
Most basement waterproofing projects in Glenside run between $2,000 and $6,500, but that range shifts based on what your basement actually needs. A straightforward interior drainage system with a sump pump installation typically lands on the lower end. Full exterior waterproofing with excavation, membrane application, and drainage work pushes toward the higher end.
Your specific cost depends on your basement’s size, how severe the water intrusion is, whether you need foundation repairs, and if we’re working with interior systems, exterior systems, or both. Crawlspace encapsulation adds to the total if that’s part of your home’s layout.
We don’t give ballpark estimates over the phone because your neighbor’s $3,000 job might have nothing to do with what your basement needs. We come out, assess the situation, and give you an actual number based on the work required—not a range that could double once we start digging.
Interior basement waterproofing in Glenside typically takes one to three days depending on your basement’s size and the system we’re installing. If we’re putting in a perimeter drainage system and sump pump, you’re usually looking at two full days of work. Smaller jobs with limited drainage needs might wrap in a day.
Exterior waterproofing takes longer—usually three to five days because we’re excavating around your foundation, applying waterproof coatings to basement walls, installing exterior drainage, and backfilling. Weather affects exterior timelines. If it’s pouring rain or the ground’s frozen, we’re not digging. Pennsylvania weather can be unpredictable that way.
Foundation crack repairs or crawlspace encapsulation can add time depending on severity. We’ll give you a realistic timeline during your estimate so you can plan accordingly. Most homeowners are surprised the work moves faster than they expected, but we’d rather underpromise and finish early than leave you waiting.
Basement waterproofing in Glenside stops the moisture that causes mold, but it doesn’t remove mold that’s already there. You need to handle existing mold separately—either yourself if it’s minor surface mold, or through professional mold remediation if it’s widespread. Once that’s done, waterproofing prevents it from coming back.
Mold needs moisture to grow. When your basement stays dry, mold doesn’t have what it needs to survive. That musty smell disappears. The air quality improves. You stop worrying about health issues, especially if you’ve got kids or anyone with respiratory problems in the house.
Some homeowners try to deal with mold without fixing the water problem. That’s backwards. You can bleach mold off your walls every month, but if water’s still seeping in, it’s coming right back. Fix the water intrusion first with proper basement waterproofing, then address the mold. That’s the order that actually works.
Interior waterproofing makes sense when water’s already getting through your foundation and you need to manage it before it damages your basement. It’s less expensive, less disruptive, and works well for homes where exterior access is difficult—like when you’ve got a deck, patio, or landscaping you don’t want to tear up. Most Glenside homes with minor to moderate seepage do fine with interior systems.
Exterior waterproofing is the move when you’re dealing with foundation cracks, persistent water pressure against your basement walls, or structural issues that need addressing from the outside. It stops water before it ever touches your foundation. If your home’s older and you’re seeing significant foundation problems, exterior work often makes more sense long-term.
Sometimes you need both. Interior drainage handles water that makes it through, while exterior waterproofing reduces how much water reaches your foundation in the first place. We’ll tell you honestly what your situation requires after we assess your basement. There’s no point in overselling exterior work if interior systems will keep you dry, and there’s no point in skipping exterior work if that’s what your foundation actually needs.
Our lifetime transferable warranty on basement waterproofing in Glenside, PA covers the waterproofing system we install for as long as you own your home—and it transfers to the next owner if you sell. If water gets through the system we installed, we come back and fix it at no cost to you. That includes labor and materials.
The warranty doesn’t cover damage from things like plumbing leaks, sewer backups, or foundation issues that develop after installation from causes unrelated to our work. It’s specifically for the waterproofing system’s performance. If our drainage system fails, if the sump pump we installed stops working properly, if water finds a way through despite our waterproofing—we handle it.
Most basement waterproofing companies in Glenside either don’t offer lifetime warranties or they’re loaded with exclusions that make them worthless. Ours is straightforward. We stand behind the work because we’ve been doing this for 15 years and we know our systems hold up. You’re not paying for something that might last five years. You’re paying for a permanent solution.
Your basement should be dry immediately after we finish the installation, but the real test comes with the next significant rain. That’s when you’ll see the system working—water that used to pool on your floor or seep through walls gets redirected through the drainage system and pumped out before you ever see it.
If there’s existing moisture in your concrete or walls from previous water intrusion, that can take a few weeks to fully dry out even after waterproofing is complete. Concrete holds moisture. Running a dehumidifier speeds that process up. But new water stops coming in right away.
Some homeowners expect their basement to feel different the day we finish. It will, but the dramatic difference hits after that first storm when you head downstairs expecting to see water—and there’s nothing. That’s when it clicks that the problem’s actually solved. Most customers call or text us after that first big rain just to say their basement stayed completely dry. That’s what you’re paying for.
