Foundation Crack Repair Process

How We Fix Foundation Cracks Right

First, we inspect your foundation to determine what’s causing the cracks and whether they’re active or stable. This tells us which repair method will work best and helps identify any other areas that need attention.

For most foundation cracks, we use professional crack injection with polyurethane or epoxy materials. We clean out the crack, install injection ports, and pump the material under pressure until it completely fills the crack from inside to outside. This creates a flexible, waterproof seal that moves with your foundation.

After the injection cures, we test the repair and clean up the work area. You get a foundation that’s structurally sound and watertight. The repair is often stronger than the original concrete, and you can see exactly what was done to fix the problem.

Complete Foundation Crack Repair Solutions

Our foundation crack repair covers everything from hairline cracks to significant structural fissures. We handle basement wall crack repair, foundation leak repair, and structural integrity restoration using professional crack injection techniques.

East Quogue homes face unique challenges from coastal weather and soil conditions. We’ve repaired foundation cracks in homes from Dune Road waterfront properties to inland neighborhoods, and we understand how different foundation types respond to local conditions.

Every repair includes a thorough assessment of your entire foundation, professional-grade materials that are designed for Long Island conditions, and a warranty that backs our work. You get honest answers about what needs repair and what doesn’t, plus solutions that address the actual problem instead of just covering it up.

A large vertical crack runs through a concrete foundation wall beneath a wooden structure, with soil, grass, and a black pipe visible at the base.
Any crack that’s wider than a hairline, shows signs of recent movement, or allows water seepage needs professional attention. Horizontal cracks are particularly serious and require immediate evaluation. If you can fit a coin into the crack, or if you notice the crack has grown since you first spotted it, don’t wait. Even small cracks can allow water infiltration that leads to bigger problems. The key is getting an honest assessment from someone who knows the difference between normal settling and structural issues.
Crack injection uses polyurethane or epoxy materials pumped under pressure to completely fill and seal the crack from inside the wall to the exterior. This creates a permanent, flexible seal that moves with your foundation. Other methods like surface patching or interior sealants only address the visible crack without filling the entire fissure. Professional injection actually strengthens the repaired area and provides real waterproofing, while surface treatments often fail when the foundation moves or settles.
Most foundation crack repairs take 2-4 hours depending on the number and size of cracks. The actual injection process is relatively quick, but proper preparation and curing time are important for lasting results. You’ll need to stay out of the immediate work area, but the rest of your home isn’t affected. We clean up completely when finished, and you can use your basement normally once the materials cure, usually within 24 hours.
Proper crack repair stops the specific crack from spreading and prevents water infiltration at that location. However, if underlying issues like poor drainage or ongoing settlement aren’t addressed, new cracks can form elsewhere. That’s why we evaluate your entire foundation and identify contributing factors like drainage problems or soil issues. We’ll tell you if additional work is needed to prevent future problems, but we won’t oversell services you don’t need.
Foundation crack repair costs depend on the crack size, location, and repair method needed. Simple crack injection typically costs much less than major structural repairs or foundation replacement. We provide upfront pricing after evaluating your specific situation. Most homeowners find that addressing cracks early saves significant money compared to waiting until water damage or structural problems develop. We’ll give you honest pricing and explain exactly what work is necessary versus optional.
Yes, our foundation crack repairs come with a warranty that covers both materials and workmanship. The specific warranty terms depend on the type of repair and conditions, but we stand behind our work. If a properly repaired crack fails due to our workmanship or materials, we’ll fix it at no charge. We use professional-grade materials designed for Long Island conditions and proven injection techniques that provide lasting results when applied correctly.
