You stop losing half your house to dampness and that musty smell. You can actually use your basement for storage, a workspace, or extra living area without worrying about ruined belongings every time it rains.
Your home value goes up—sometimes by as much as 30% with a properly waterproofed basement. More importantly, you’re not dealing with mold that gets into your HVAC system and affects the air your family breathes upstairs.
The constant stress of checking the basement after every storm? Gone. You’re not running a shop-vac down there or waiting days for floors to dry. East Norriton sits on clay soil that holds water like a sponge, and when that soil presses against your foundation, water finds a way in. Fixing that pressure problem means your basement stays dry year-round, not just until the next heavy rain.
Del Val Basement Waterproofing is a family-run company that’s been handling foundation and basement waterproofing across Montgomery County for over 15 years. We’re local to the Delaware Valley, so we know exactly what East Norriton basements deal with—clay soil, heavy spring rains, and foundations that weren’t built to handle the water pressure this area creates.
You get the experience of a large waterproofing company without the corporate runaround. We show up, assess the actual problem, explain what needs to happen, and give you a fair price with a lifetime transferable warranty. No pressure tactics, no selling you things you don’t need.
East Norriton homeowners deal with older foundations and soil that shifts with the seasons. We’ve seen it all, and we fix it right the first time.
First, we come out for a free estimate and actually inspect your basement—not just the visible water damage, but where it’s coming from. Most water problems in East Norriton come from hydrostatic pressure pushing groundwater through foundation walls or up through the floor. We identify the source.
Then we recommend the right fix. That might be our Sub Floor Pressure Relief System, which handles water before it even gets into your basement. It’s a more reliable alternative to old French drains that fail over time. For some homes, we’ll do interior waterproofing with drainage systems and sealants. For others, exterior waterproofing with excavation and waterproof membranes makes more sense.
During installation, you can stay in your home. The work is minimally invasive—some noise and dust, but nothing that forces you out. Once we’re done, we test the system and walk you through how it works. Then we back it with a lifetime warranty that transfers if you sell. You’re covered, and so is the next owner.

You get a full assessment of your foundation and basement, not a cookie-cutter solution. We look at your soil type, grading, drainage, and where water is actually entering. In East Norriton, that usually means dealing with clay soil that expands when wet and contracts when dry, which shifts your foundation and creates new cracks.
We use interior drainage systems, sump pumps, vapor barriers, and exterior waterproofing depending on what your home needs. We also handle basement wall waterproofing with sealants and membranes that stop water at the source. If your foundation has cracks, we repair those with modern materials like carbon fiber reinforcement.
The work comes with a lifetime transferable warranty. That’s not a gimmick—it means we’re confident the system will last as long as you own the home, and it adds value when you sell. East Norriton gets 35 to 54 inches of rain a year, with the heaviest storms hitting in March and April. Your basement needs to handle that, and our systems do.
Most basement waterproofing jobs in East Norriton run between $3,000 and $10,000, depending on the size of your basement and the severity of the water problem. If you need exterior excavation or major foundation repairs, costs can go higher.
Interior waterproofing with drainage systems and sump pumps is usually on the lower end. Exterior waterproofing—where we dig around the foundation and apply waterproof membranes—costs more but handles water before it ever touches your walls. Northeast homes like the ones in East Norriton tend to be older with higher water tables, which is why costs here run a bit higher than other parts of the country.
We give free estimates and break down exactly what you’re paying for. No hidden fees, no upselling. You’ll know the cost upfront and what it includes.
Yes. Basement waterproofing is non-invasive enough that you can stay home during the work. There will be some noise from equipment and a bit of dust, but it’s not a gut-rehab situation.
If we’re doing interior work, we’re usually in your basement for a few days. Exterior waterproofing takes longer because we’re excavating around the foundation, but that’s all happening outside. You’ll still have full access to your home.
We keep the work area contained and clean up at the end of each day. Most East Norriton homeowners don’t need to leave, and daily routines stay pretty normal. If you work from home or have young kids, we’ll work with you on timing to minimize disruption.
A properly installed basement waterproofing system lasts for decades—often the lifetime of your home. Our systems come with a lifetime transferable warranty because we know they’re built to last.
Interior drainage systems and sump pumps need occasional maintenance, like cleaning out the sump pit or checking the pump, but the core system doesn’t degrade. Exterior waterproofing membranes can last 50+ years without needing replacement. The key is doing it right the first time, which means addressing the actual water source and not just patching symptoms.
East Norriton’s clay soil and seasonal weather put constant pressure on foundations, so a system that works here has to be robust. Ours are. We’ve been installing them since 2007, and the early jobs are still keeping basements dry today.
Clay soil. East Norriton sits on soil that absorbs water and swells, then contracts when it dries out. That constant expansion and contraction creates pressure against your foundation walls, forcing water through cracks or up through the floor.
Add in 35 to 54 inches of rain per year—most of it during spring storms—and you’ve got water pooling around foundations that weren’t built to handle that kind of load. Older homes in the area often lack proper exterior drainage or have outdated waterproofing that’s failed over time.
Hydrostatic pressure is the real culprit. When groundwater saturates the soil around your foundation, it pushes inward with enough force to seep through concrete. That’s why surface fixes like sealing cracks from the inside don’t work long-term. You have to relieve that pressure or redirect the water before it reaches your walls.
Yes. We back every basement waterproofing job in East Norriton, PA with a lifetime transferable warranty. That means if the system fails, we come back and fix it at no cost to you. If you sell your home, the warranty transfers to the new owner, which adds value and makes your home easier to sell.
We’re confident enough in our work to guarantee it for life because we use proven systems and install them correctly. We’re not patching problems—we’re solving them at the source. That’s why we can offer a warranty this strong.
Most waterproofing companies either don’t offer warranties or limit them to 10-20 years. Ours doesn’t expire. You’re covered as long as you own the home, and so is the next owner.
Interior waterproofing manages water that’s already made it to your foundation. We install drainage systems along the basement floor perimeter, direct water to a sump pump, and pump it out. We also apply sealants to walls and floors to reduce moisture. It’s less invasive and more affordable, and it works well for managing minor to moderate water issues.
Exterior waterproofing stops water before it reaches your foundation. We excavate around the outside of your home, apply waterproof membranes to the foundation walls, and install drainage systems that redirect groundwater away. It’s more comprehensive and handles severe water problems, but it costs more and takes longer.
In East Norriton, we often recommend a combination. The clay soil here creates hydrostatic pressure that’s tough to manage with interior systems alone. Exterior waterproofing relieves that pressure at the source, while interior systems provide backup protection. We assess your specific situation and recommend what actually makes sense for your home and budget.
