Basement Crack Repair Experts

We Know Long Island Foundations

We’ve been fixing foundation problems across Long Island for years. We understand how the local clay soil shifts and settles, especially during our freeze-thaw cycles.

Most foundation cracks here aren’t catastrophic – they’re predictable results of our soil conditions. But they need proper repair, not temporary patches that fail in two years.

We’ve seen what works and what doesn’t. Our approach focuses on permanent solutions using proven crack injection techniques and quality materials that actually last.

Foundation Crack Injection Process

Here's Exactly What We Do

First, we assess the crack to determine if it’s structural or settlement-related. This tells us which repair method will actually work long-term.

For active cracks, we use professional-grade polyurethane or epoxy injection. We drill small ports along the crack, inject the material under pressure, and seal it permanently. The injection fills the entire crack depth, not just the surface.

For structural issues, we may recommend additional reinforcement or waterproofing measures. We’ll explain exactly what your foundation needs and why, so you understand what you’re paying for.

The area gets cleaned up, and you get a repair that stops water infiltration and prevents the crack from reopening.

What's Included in Foundation Crack Repair

You get a thorough assessment of the crack’s cause and severity. We don’t just fix what’s visible – we identify why it happened and address the root issue.

Professional crack injection using commercial-grade materials designed for Long Island’s soil conditions. This isn’t hardware store crack filler that peels off in a few seasons.

We handle both basement wall cracks and exterior foundation issues. Interior repairs stop water infiltration immediately, while exterior work addresses drainage and soil pressure problems.

If your foundation needs additional waterproofing or structural reinforcement, we’ll handle that too. The goal is solving your foundation problems completely, not creating a list of future service calls.

How do I know if my foundation crack is serious?

Horizontal cracks, cracks wider than a quarter-inch, or cracks that are actively growing need immediate attention. These often indicate structural movement or soil pressure issues. Vertical cracks are usually less concerning but still need proper sealing to prevent water damage. If you can fit a coin in the crack or if it’s gotten noticeably larger over time, call for an assessment. We can tell you whether it’s a cosmetic issue or something that requires structural repair.

Will crack injection actually stop water from coming through?

Yes, when done properly with the right materials. Professional polyurethane injection expands to fill the entire crack depth and creates a waterproof seal. However, surface patching or DIY crack fillers usually fail because they don’t penetrate deep enough. The key is using commercial-grade injection materials and proper pressure techniques to ensure complete crack filling. We’ve stopped leaks in cracks that homeowners tried to fix multiple times with store-bought products.

How long does foundation crack repair last?

Professional crack injection should be permanent when the underlying cause is addressed. If the crack was caused by normal settling, a quality repair will last indefinitely. However, if ongoing soil movement or drainage issues aren’t fixed, new cracks may develop nearby. That’s why we assess the cause first – sometimes you need drainage improvements or soil stabilization along with the crack repair. A proper repair using quality materials should never need to be redone.

Can I just seal foundation cracks from the inside?

Interior crack injection stops water infiltration immediately and is often the most practical solution. However, some situations require exterior work too, especially if you have drainage problems or soil pressure against the foundation. Interior repairs are less disruptive and usually more cost-effective, but we’ll tell you if exterior work is necessary for a complete solution. Many foundation problems can be permanently fixed from inside your basement without any excavation.

What causes foundation cracks in Long Island homes?

Long Island’s clay soil expands when wet and contracts when dry, creating pressure against foundations. Our freeze-thaw cycles make this worse – water gets into small cracks, freezes, and expands the crack further. Most homes here develop some foundation cracks as they settle, especially in the first few years. Poor drainage around the foundation accelerates the problem by keeping soil saturated. These are predictable issues that respond well to proper repair techniques.

How much does foundation crack repair typically cost?

Simple crack injection usually costs much less than homeowners expect, especially compared to the potential water damage costs of leaving cracks unsealed. The price depends on crack length, location, and whether additional waterproofing is needed. Most residential crack repairs are straightforward jobs that don’t require major excavation or structural work. We provide upfront pricing after assessing your specific situation – no surprises or pressure tactics. The investment is minimal compared to protecting your home’s foundation and value.
