Foundation Crack Repair Process

Here's Exactly What We Do

First, we inspect your foundation thoroughly to identify all problem areas, not just the obvious cracks you can see. Many Belle Terre homes have multiple issues that need addressing at once.

Next, we clean and prepare each crack using professional equipment. For most foundation cracks, we use high-pressure polyurethane or epoxy injection that penetrates deep into the concrete, creating a seal that’s actually stronger than the original foundation.

After the injection cures, we test the repair and clean up completely. You’ll see the difference immediately, but the real proof comes during the next heavy rainstorm when your basement stays completely dry.

Most foundation crack repairs in Belle Terre take 4-8 hours depending on the number and size of cracks. Simple crack injection can often be completed in half a day, while more extensive structural repairs might take 1-2 days. We work efficiently to minimize disruption to your daily routine. The actual repair process is much faster than most homeowners expect – the time-consuming part is the thorough inspection and proper preparation that ensures the repair lasts permanently.
Belle Terre’s clay soil expands and contracts significantly with moisture changes, putting constant pressure on foundations. The seasonal freeze-thaw cycles common on Long Island also cause soil movement that leads to foundation settling and cracking. Additionally, many Belle Terre homes were built in the 1950s-1980s when foundation construction standards were different. Poor drainage around the foundation and tree roots can also contribute to cracking over time.
Professional crack injection using polyurethane or epoxy creates a permanent repair that’s often stronger than the original concrete. The key is using the right material for your specific crack type and ensuring proper preparation. DIY crack repair products from hardware stores are temporary, but professional-grade injection materials are designed to last decades. We warranty our crack injection work because we’re confident in the permanence of properly executed repairs.
Foundation crack repair costs vary based on crack size, location, and complexity, but most Belle Terre homeowners spend between $400-$1,500 for professional crack injection. Simple hairline cracks cost less, while structural cracks requiring extensive preparation cost more. We provide upfront pricing after inspection so you know exactly what you’re paying before work begins. Compared to the cost of major foundation damage or basement flooding, professional crack repair is an excellent investment.
Most foundation crack repairs can be completed from inside your basement without any excavation. Crack injection is typically done from the interior, which means no damage to your landscaping or disruption to your property. Excavation is only necessary for severe structural issues or when exterior waterproofing is required. We always try the least invasive approach first, and most Belle Terre homeowners are surprised how much we can accomplish without digging.
Call immediately if you see water seepage, cracks wider than a quarter-inch, or cracks that are growing. Even hairline cracks should be addressed promptly because Belle Terre’s freeze-thaw cycles will make them worse over time. Foundation problems never improve on their own and always become more expensive to fix when delayed. The best time for repair is as soon as you notice the problem, before water damage or structural issues develop.
