Foundation Crack Repair Process

Here's Exactly What We Do

First, we inspect your foundation cracks to determine what’s causing them and whether they’re structural or settlement-related. You get a clear explanation of what we find, no technical jargon or scare tactics.

Next, we prepare the crack properly and use professional crack injection techniques to fill it with high-strength polyurethane or epoxy. This isn’t caulk or surface patching – it’s a permanent repair that bonds with your concrete and flexes with normal house movement.

Finally, we clean up completely and explain what to watch for going forward. Most repairs cure within hours, and you can see immediately that the crack is sealed properly. We also let you know if there are other areas that might need attention down the road.

Basement Wall Crack Repair

What's Included in Every Repair

Every foundation crack repair includes a thorough assessment of your entire foundation, not just the obvious problem areas. We identify whether cracks are active or dormant and explain what that means for your specific situation.

You get professional-grade crack injection using materials designed for Long Island’s soil conditions and climate. We don’t use hardware store products or temporary fixes that fail after the first freeze-thaw cycle.

We also provide honest recommendations about drainage improvements or other preventive measures that could save you money long-term. Sometimes fixing the crack isn’t enough if water is still pooling against your foundation or if grading issues aren’t addressed.

How do I know if my foundation crack needs professional repair?

Any crack that’s wider than a quarter-inch, actively leaking water, or growing larger over time needs professional attention. Horizontal cracks are more serious than vertical ones, and cracks that have white mineral deposits around them indicate ongoing water infiltration. If you can stick a coin into the crack or if it’s allowing water into your basement, don’t wait. Even smaller cracks can become major problems during freeze-thaw cycles, so it’s better to address them before they spread.

What's the difference between crack injection and just sealing the surface?

Surface sealing with caulk or hydraulic cement only covers the crack temporarily – it doesn’t actually repair the concrete. Crack injection uses pressurized polyurethane or epoxy that penetrates deep into the crack, bonding with the concrete and creating a permanent seal that’s often stronger than the original concrete. Surface treatments typically fail within a year or two, especially through Long Island’s freeze-thaw cycles, while proper crack injection repairs last for decades when done correctly.

How long does foundation crack repair take and will it disrupt my home?

Most foundation crack repairs take 2-4 hours depending on the number and size of cracks. The actual injection process is quick, but proper preparation and curing time are important for lasting results. You can usually use your basement the same day, though we recommend avoiding heavy water use near the repair area for 24 hours. There’s no excavation required for most crack injection repairs, so your landscaping and daily routine aren’t disrupted. The biggest inconvenience is usually just having us in your basement for a few hours.

Will foundation crack repair prevent water from getting into my basement?

Properly executed crack injection creates a watertight seal that prevents water infiltration through the repaired crack. However, if you have multiple foundation issues, poor drainage, or other entry points for water, you might need additional waterproofing measures. We’ll identify any other potential problem areas during our inspection and let you know if crack repair alone will solve your water issues or if you need a more comprehensive approach. Most single-crack water problems are completely resolved with professional injection repair.

How much does foundation crack repair cost in Levittown?

Foundation crack repair costs depend on the crack’s size, location, and complexity, but most residential repairs range from several hundred to over a thousand dollars per crack. Horizontal cracks or those requiring structural reinforcement cost more than simple vertical settlement cracks. We provide upfront pricing after inspecting your specific situation – no surprises or hidden fees. While it might seem expensive, professional crack repair typically costs far less than dealing with water damage, mold remediation, or major structural repairs that result from ignoring foundation problems.

Do you warranty your foundation crack repair work?

Yes, we stand behind our foundation crack repairs with a comprehensive warranty that covers both materials and workmanship. The specific warranty terms depend on the type of repair and your foundation’s condition, but we guarantee that properly repaired cracks won’t leak or reopen when the work is done correctly. We’ll explain exactly what’s covered before starting any work, and we’re available if you have concerns after the repair is complete. Our goal is permanent solutions, not callback visits to fix the same problem repeatedly.
