Foundation Crack Repair Process

Here's Exactly How We Fix It

First, we assess the crack to determine what caused it and whether it’s structural or just settlement. Not all cracks are the same, and the repair method depends on what we’re dealing with.

For most foundation cracks, we use professional-grade polyurethane or epoxy injection. We clean out the crack, install injection ports, and pump the material in under pressure. This creates a permanent seal that’s actually stronger than the surrounding concrete.

The repair cures within hours, but we recommend waiting 24 hours before exposing it to water. You’ll see the difference immediately – no more seepage, no more growing cracks, no more water problems.

What's Included in Every Repair

Every foundation crack repair starts with a thorough assessment of the crack and surrounding area. We identify the root cause, not just the symptom you can see.

You get professional-grade injection materials designed for Long Island’s soil conditions and weather patterns. We use the right material for your specific situation – polyurethane for active leaks, epoxy for structural repairs.

We also check for other potential problem areas while we’re there. Often, fixing one crack prevents others from developing. You’ll get recommendations for any additional preventive measures that make sense for your foundation.

Professional crack injection creates a permanent repair when done correctly. The polyurethane and epoxy materials we use are designed to last the life of your foundation. They’re actually stronger and more flexible than the original concrete, so they move with your foundation as it naturally settles. The key is using the right material for your specific crack type and soil conditions. We’ve seen properly injected cracks remain watertight for decades, even through Long Island’s freeze-thaw cycles.
Yes, proper crack injection stops water infiltration through the repaired crack. The materials we inject expand and cure to create a waterproof seal that prevents any moisture from passing through. However, if you have water issues elsewhere in your foundation, those need to be addressed separately. We always check for other potential entry points during our assessment. The goal is solving your water problem completely, not just patching one spot while water finds another way in.
Any crack that’s allowing water through needs professional attention immediately. Horizontal cracks, cracks wider than a quarter inch, or cracks that are growing also require professional assessment. Even hairline cracks can become major problems if they’re in the wrong location or caused by ongoing settlement. The freeze-thaw cycles here in East Setauket can turn small cracks into big ones quickly. When in doubt, get it looked at. A professional assessment costs much less than dealing with major water damage or structural issues later.
Long Island’s clay-heavy soil is the main culprit. Clay expands when wet and contracts when dry, putting constant pressure on your foundation walls. Our freeze-thaw cycles make this worse – water gets into small cracks, freezes and expands, then thaws and allows more water in. Many homes in East Setauket were built in the 1950s-1980s when foundation techniques weren’t as advanced as today. Normal settlement over decades, combined with our soil conditions, creates the perfect environment for foundation cracks to develop.
Most single crack repairs range from a few hundred to around a thousand dollars, depending on the crack’s length, location, and complexity. That’s significantly less than dealing with ongoing water damage, mold remediation, or major structural repairs down the road. The cost depends on factors like crack size, accessibility, and whether we’re dealing with an active leak or structural issue. We provide detailed written estimates that break down exactly what you’re paying for. No surprises, no hidden fees.
DIY crack sealers from hardware stores are temporary fixes at best. They don’t address the root cause and often fail within months, especially with our weather conditions. Professional injection equipment creates pressure that forces repair material deep into the crack, creating a permanent bond. We also have access to commercial-grade materials that aren’t available to consumers. Attempting DIY repairs can sometimes make professional repairs more difficult and expensive later. If the crack is worth fixing, it’s worth fixing right the first time.
