When we seal your foundation cracks properly, water stops coming through your basement walls. You stop worrying about mold growing behind your drywall or your finished basement getting ruined every time it rains hard.
The air in your house gets cleaner because moisture isn’t feeding mold spores anymore. Your foundation stops shifting and settling because we’re addressing what’s causing the cracks in the first place, not just covering them up.
You protect your property value instead of watching it drop because buyers see water stains and foundation problems. And you stop throwing money at temporary fixes that fail six months later when the next freeze-thaw cycle hits.
Del Val Basement Waterproofing is a family-run company that understands what Exton homeowners deal with. The clay-rich soil around here expands when it’s wet and contracts when it dries out, putting constant pressure on your foundation walls.
We’ve seen what happens when contractors take shortcuts or miss the root cause. That’s why we dig deeper to figure out why your foundation is cracking, not just patch the surface and hope for the best.
Every basement foundation crack repair in Exton, PA that we complete comes with a lifetime transferable warranty. We’re not going anywhere, and neither is our commitment to keeping your foundation stable.
First, we inspect your foundation inside and out to find every crack and figure out what’s causing them. Sometimes it’s hydrostatic pressure from poor drainage. Sometimes it’s settlement from soil movement. We need to know before we fix anything.
Next, we tackle the problem from the outside when possible. Exterior foundation crack repair in Exton, PA means we excavate down to the foundation, seal the cracks with professional-grade materials, and apply a waterproof barrier that stops moisture before it ever reaches your basement walls.
For cracks that need interior work, we use epoxy or polyurethane injection to fill and seal them completely. This isn’t caulk from a hardware store. It’s engineered material that bonds with the concrete and flexes with minor movement without breaking the seal.
Then we address drainage issues around your foundation so water stops pooling against your walls. That might mean regrading, installing or repairing gutters and downspouts, or adding exterior drainage systems. If water isn’t sitting against your foundation, it can’t push through cracks.
Ready to get started?
You get a thorough inspection that identifies every crack and the conditions causing them. We don’t just fix what you can see and call it done.
You get professional crack sealing using methods that match your specific situation. Vertical cracks get treated differently than horizontal ones. Active cracks that are still moving get reinforced. Leaking basement wall repair in Exton, PA requires stopping the water source, not just patching the symptom.
You get exterior waterproofing when it makes sense for your situation. Pennsylvania’s freeze-thaw cycles are brutal on foundations. Sealing from the outside creates a barrier that handles temperature swings and moisture better than interior-only repairs.
You get honest answers about what your foundation needs and what it doesn’t. Some contractors will sell you a full excavation when a crack injection would work fine. We’re not those guys. Our reputation in Exton depends on doing right by people, not maximizing every invoice.
Most residential foundation crack repair in Exton, PA runs between $500 and $2,500 depending on how many cracks you have, where they’re located, and what’s causing them. Simple vertical cracks that aren’t actively leaking might cost $500 to $800 to inject and seal.
Larger jobs that need exterior excavation, multiple crack repairs, and drainage corrections can run $2,000 to $5,000. If your foundation has structural issues like bowing walls or major settlement, you’re looking at more extensive work with steel reinforcement or wall anchors, which costs more but prevents catastrophic failure.
The real cost is what happens if you wait. A $500 crack repair today can turn into a $15,000 structural repair in two years if water keeps getting in and freeze-thaw cycles keep making it worse. Exton’s clay soil doesn’t do foundations any favors when water is involved.
Most cracked foundation repair in Exton, PA takes one to three days depending on the scope. Simple interior crack injection on a few vertical cracks can be done in a few hours once we’re on site.
Exterior foundation crack repair takes longer because we need to excavate, let things dry if it’s been raining, seal the cracks, apply waterproofing membrane, and backfill properly. That’s usually a two to three day job, sometimes longer if we’re also installing drainage systems or dealing with access issues around your property.
Weather affects the timeline too. We can’t excavate in a downpour, and some sealing materials need dry conditions to cure properly. We’d rather take an extra day and do it right than rush through and have you calling us back in six months because water is coming through again.
Yes, if it’s done correctly and addresses the water source. Professional foundation crack repair in Exton, PA seals the cracks so water can’t pass through them anymore. But if you’ve got serious drainage problems or hydrostatic pressure pushing water against your foundation, sealing cracks is only part of the solution.
That’s why we look at the whole picture. If your gutters are dumping water right next to your foundation, or your yard slopes toward your house, or you’ve got a high water table pushing up from below, we need to handle those issues too. Otherwise you’re just playing whack-a-mole with leaks.
When we seal cracks and fix drainage problems together, your basement stays dry. The warranty we provide backs that up. We’re not interested in temporary fixes that fail when the next heavy rain hits.
Exton’s clay-rich soil is the biggest culprit. Clay expands when it absorbs water and shrinks when it dries out. That constant movement puts uneven pressure on your foundation walls, causing cracks over time.
Pennsylvania’s freeze-thaw cycles make it worse. Water gets into small cracks, freezes and expands in winter, then thaws in spring. Each cycle makes the crack a little bigger. After a few years, you’ve got a crack that’s leaking every time it rains.
Poor drainage accelerates everything. If water pools around your foundation because your gutters are clogged or your yard slopes the wrong way, that water is constantly pushing against your foundation walls. Eventually something has to give. Settlement from soil erosion or improper compaction during construction causes cracks too, especially in older homes.
Outside is better when it’s possible. Exterior foundation crack repair in Exton, PA stops water before it reaches your basement walls. You’re creating a waterproof barrier on the side where the water actually is, which makes more sense than waiting for it to leak through and trying to catch it on the inside.
The problem is that exterior repair costs more because of excavation. You’re digging down to the foundation, which means moving soil, possibly removing landscaping, and doing more labor-intensive work. But the results last longer and handle Exton’s weather better.
Interior crack injection works well for cracks that aren’t actively leaking or when excavation isn’t practical because of how your property is laid out. We inject epoxy or polyurethane into the crack from inside, which fills it completely and creates a seal. It’s faster and less expensive, but it doesn’t address exterior moisture or drainage issues. Sometimes you need both approaches depending on what’s going on with your specific foundation.
Not necessarily, but they need attention. Most foundation cracks in Exton, PA start as minor issues that won’t collapse your house tomorrow. Vertical cracks less than a quarter inch wide are common in concrete foundations and usually aren’t structural emergencies.
Horizontal cracks are more serious because they indicate pressure pushing your wall inward. Stair-step cracks in block foundations, cracks wider than a quarter inch, or cracks that are getting bigger over time need a professional foundation crack repair contractor in Exton, PA to evaluate them soon.
The danger isn’t usually immediate collapse. It’s that small cracks let water in, which leads to mold, wood rot in your floor joists, and progressive foundation damage that gets exponentially more expensive to fix. A crack that would cost $500 to seal today might need $5,000 in structural repairs if you ignore it for two years. Get them checked out before they turn into bigger problems.
