Your Foundation Problems Actually Get Fixed

You notice that crack in your basement wall during the last heavy rain. Water’s seeping through, and you’re wondering if this is just the beginning of a bigger problem.

Here’s what happens when foundation cracks get properly repaired. The water stops coming in. That musty smell in your basement disappears. You stop worrying every time it rains hard whether you’ll find a puddle downstairs.

More importantly, you know your home’s structural integrity is protected. Foundation crack repair isn’t just about stopping water – it’s about preventing small problems from becoming expensive disasters. When cracks are sealed correctly with professional injection techniques, they stay sealed. Your basement stays dry, your foundation stays stable, and you get back to not thinking about your foundation at all.

We Actually Know Foundation Repair

We handle foundation problems throughout Huntington and Long Island. We understand how coastal weather and local soil conditions affect foundations here.

Most foundation issues we see could have been prevented with early intervention. That’s why we focus on thorough assessments and permanent repairs rather than quick fixes that fail in two years.

We’ve been working with Long Island foundations long enough to know which repair methods actually last and which ones just buy you time. When we repair foundation cracks, we’re thinking about how that repair will hold up through nor’easters, freeze-thaw cycles, and everything else this area throws at foundations.

Foundation Crack Injection Process

Here's How We Fix Foundation Cracks

First, we assess the crack to determine if it’s structural or just settling. Not all cracks are the same, and the repair method depends on what’s causing the crack and where it’s located.

For most foundation cracks, we use professional injection techniques. We clean out the crack, install injection ports, and pump in polyurethane or epoxy material under pressure. This fills the entire crack from inside the wall, not just the surface you can see.

The material we inject expands slightly as it cures, creating a watertight seal that’s often stronger than the surrounding concrete. We test each repair to make sure it’s completely sealed before we finish the job.

For structural cracks, we might need additional reinforcement or different repair methods. We’ll explain exactly what your foundation needs and why, so you understand what you’re getting.

What's Included in Foundation Crack Repair

Every foundation repair starts with a complete assessment of your foundation’s condition. We don’t just fix the crack you called about – we identify other potential problems before they start leaking.

Our crack injection process includes cleaning and preparing the crack, installing injection equipment, and filling the crack with professional-grade sealant material. We also check for related issues like poor drainage or settlement that might cause new cracks.

You get a repair that’s designed to last. We use materials rated for below-grade applications that won’t break down from moisture or temperature changes. Most importantly, we explain what caused the crack so you can prevent similar problems in other areas of your foundation.

Horizontal cracks are usually more concerning than vertical ones, and any crack you can fit a coin into needs professional attention. But the real issue isn’t always the size – it’s whether the crack is active (still growing) or stable. Cracks that leak water, have white mineral deposits, or show signs of recent movement should be evaluated quickly. If you’re seeing new cracks or existing cracks getting longer, that suggests ongoing foundation movement that needs to be addressed. The location matters too – cracks near corners or under windows often indicate settlement issues that go beyond just sealing the crack.
Professional crack injection creates a permanent water seal when done correctly. The polyurethane material we inject expands as it cures, filling the entire crack through the wall thickness, not just the surface. However, injection only works if the crack isn’t actively moving. If your foundation is still settling or shifting, new cracks can develop. That’s why we assess the underlying cause before recommending injection. For stable cracks, injection provides a reliable long-term solution. We’ve seen properly injected cracks stay dry for decades, even through major storms and seasonal ground movement.
Most foundation crack repairs range from a few hundred to a couple thousand dollars, depending on the crack’s size, location, and complexity. Simple injection repairs are less expensive than structural repairs that require excavation or reinforcement. The cost also depends on how many cracks need attention – sometimes what looks like one problem is actually several related issues. We provide upfront pricing after assessing your specific situation. Keep in mind that early repair is almost always less expensive than waiting. Small cracks that get injected now cost much less than major structural work later if the problem spreads.
Most crack injection repairs take a few hours to complete, but the material needs time to cure before it’s fully effective. Simple repairs can often be finished in half a day, while more complex structural work might take several days. Weather affects the timeline since some materials don’t cure properly in extreme temperatures. We’ll give you a realistic timeframe based on your specific repair needs. The curing process is important – rushing it leads to failed repairs. Most injection materials reach full strength within 24-48 hours, but you’ll typically see the leak stop immediately after injection.
Surface sealers and DIY crack fillers rarely provide lasting solutions for foundation problems. These products might stop minor seepage temporarily, but they don’t address the crack through the full wall thickness. Professional injection equipment creates pressure that forces material deep into the crack, something you can’t achieve with surface applications. More importantly, you need to know whether the crack indicates a larger structural issue. If the foundation is still moving, surface repairs will just crack again. Professional assessment helps you understand what you’re really dealing with and whether simple injection is sufficient or if you need more comprehensive foundation work.
Foundation cracks typically result from settlement, water pressure, or thermal expansion. In Long Island, we see a lot of cracks caused by seasonal ground movement – soil expands when wet and contracts when dry, putting stress on foundation walls. Poor drainage around the foundation creates hydrostatic pressure that can crack walls over time. Sometimes cracks are just normal settling as the house adjusts to its foundation, especially in newer construction. Tree roots, plumbing leaks, and changes in soil moisture all contribute to foundation movement. Understanding the cause helps determine the right repair approach and prevent future problems in other areas of your foundation.
