Foundation Crack Repair Process

How We Fix Foundation Cracks Permanently

First, we inspect your entire foundation to identify all problem areas, not just the obvious cracks. Many homeowners are surprised to learn they have multiple issues that need attention before they become bigger problems.

Next comes the actual repair work. For most foundation cracks, we use professional crack injection methods that seal the crack from the inside out. This isn’t the surface patching you might have tried before. We’re filling the entire crack with materials that bond with your concrete and flex with natural foundation movement.

For structural cracks or more complex issues, we determine the root cause first. Sometimes it’s drainage. Sometimes it’s soil settlement. We fix the underlying problem so the crack doesn’t come back in six months.

What's Included in Professional Foundation Repair

Every foundation crack repair starts with a thorough assessment of your entire foundation system. We check for active leaks, measure crack width and length, and test for structural movement. You need to know exactly what you’re dealing with before any repair work begins.

Our crack injection process uses professional-grade polyurethane or epoxy materials depending on your specific situation. These aren’t hardware store products. They’re designed to permanently bond with concrete and remain flexible as your foundation experiences normal seasonal movement.

For basement wall cracks that leak, we often combine crack injection with exterior waterproofing measures. Baldwin’s heavy rain seasons put a lot of pressure on foundation walls, so addressing both the crack and the water source gives you the most reliable long-term solution.

Foundation crack repair costs vary based on the crack size, location, and underlying cause. Simple crack injection for non-structural cracks typically runs less than major excavation work. However, the real cost question is what happens if you don’t fix it. Small cracks become big cracks. Dry cracks start leaking. Minor repairs become major foundation problems. We provide upfront pricing after assessing your specific situation, so you know exactly what you’re paying for and why it’s necessary.
Crack injection stops water infiltration through the crack itself, but only if it’s done properly with the right materials. The key is identifying whether water is coming through the crack or if there are other sources like poor drainage or hydrostatic pressure. Many homeowners assume all basement water issues are crack-related, but sometimes fixing the crack is just part of the solution. We identify all water sources during our assessment so you get a complete fix, not a temporary patch.
Structural cracks typically run horizontally, show signs of recent movement, or cause doors and windows to stick. Cosmetic cracks are usually vertical, hairline width, and haven’t changed in years. However, this isn’t something you should diagnose yourself. What looks cosmetic can become structural if underlying issues aren’t addressed. We measure crack width, check for active movement, and assess what’s causing the crack in the first place. This tells us whether you need structural repair or standard crack sealing.
Most failed crack repairs happen because the underlying cause wasn’t addressed or the wrong repair method was used. Surface patching with hydraulic cement or caulk might hide the crack temporarily, but it doesn’t actually seal it. Professional crack injection penetrates the entire crack depth and bonds with the concrete. Also, if poor drainage or soil issues caused the original crack, those problems need to be fixed too. Otherwise, you’re just treating symptoms while the root cause creates new cracks.
Waiting usually costs you more money and creates bigger problems. Small cracks are easier and less expensive to repair than large ones. Dry cracks are simpler to fix than leaking cracks. Cracks that haven’t compromised structural integrity are less complex than ones that have. Foundation problems don’t improve on their own, and Long Island’s freeze-thaw cycles make existing cracks worse each winter. Early intervention almost always saves money and prevents more extensive damage to your home.
DIY crack repair typically involves surface treatments that don’t address the full crack depth or underlying causes. Professional foundation repair uses specialized injection equipment and commercial-grade materials that aren’t available to homeowners. We also identify why the crack formed in the first place, which determines the proper repair method. Some cracks need flexible sealants, others need rigid structural repair. Some require exterior work to address water pressure. Getting this wrong means the crack comes back, often worse than before.
