Foundation Crack Repair Process

Here's Exactly How We Fix Your Foundation

First, we inspect your foundation to determine what’s causing the cracks and whether they’re structural or settlement-related. This isn’t a quick glance – we’re looking at drainage, soil conditions, and the crack patterns to understand the root cause.

Next, we prepare the crack properly. Surface repairs fail because they don’t address what’s happening inside the foundation wall. We clean out loose material and prepare the crack for permanent repair using professional-grade injection methods or structural repair techniques.

Then we apply the appropriate repair method. For active leaks, we use crack injection with polyurethane or epoxy materials that stop water intrusion and restore structural integrity. For larger structural issues, we may recommend additional reinforcement or drainage improvements.

Finally, we test our work and provide you with documentation of what we’ve done, including warranty information and maintenance recommendations to prevent future problems.

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

Any crack that’s actively leaking water, growing larger, or wider than a quarter-inch should be professionally evaluated. Horizontal cracks are typically more serious than vertical ones, and cracks that allow you to see daylight through them definitely need attention. If you’re seeing new cracks after heavy rains or if existing cracks are changing, that’s a sign of ongoing foundation movement that needs professional assessment. Don’t wait until a small problem becomes a major structural issue.

What's the difference between crack injection and other foundation repair methods?

Crack injection uses specialized polyurethane or epoxy materials that are injected directly into the crack under pressure, filling the entire depth of the crack and creating a permanent seal. Surface patching only covers the crack from the inside, leaving the structural integrity compromised and allowing water to find new ways in. Crack injection actually restores the structural integrity of the foundation wall while stopping water intrusion. It’s the most effective method for most foundation cracks and comes with better long-term warranties than surface repairs.

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

Most foundation crack repairs can be completed in a few hours to a full day, depending on the number and severity of cracks. The process is done from inside your basement, so there’s no excavation or major disruption to your yard or landscaping. You can typically use your basement normally within 24 hours of completion. We protect your belongings and clean up thoroughly when we’re finished. The biggest inconvenience is usually just having contractors in your basement for a day.

Will my foundation crack repair be covered by warranty?

Yes, we provide written warranties on our foundation crack repair work. The warranty length depends on the type of repair and materials used, but typically ranges from several years to lifetime coverage against water intrusion through the repaired crack. We’ll explain exactly what’s covered before we start work. Keep in mind that warranties cover the specific crack we repair – they don’t cover new cracks that may develop elsewhere in your foundation due to ongoing settlement or drainage issues.

How much does foundation crack repair cost in Port Washington?

Foundation crack repair costs vary based on the crack size, location, and repair method needed. Simple crack injection repairs typically cost significantly less than major structural repairs or exterior excavation work. We provide detailed written estimates that break down exactly what work is needed and why. Most homeowners find that professional crack repair costs much less than they expected, especially compared to the potential cost of water damage or major structural problems if cracks are left untreated.

Can foundation cracks come back after they're repaired?

Properly repaired cracks using professional injection methods rarely reopen. However, new cracks can develop if the underlying causes aren’t addressed – things like poor drainage, soil settlement, or hydrostatic pressure. That’s why we evaluate your entire foundation and drainage situation, not just patch visible cracks. We’ll recommend additional measures like drainage improvements or regular maintenance if needed to prevent future problems. A quality repair with proper materials should last for decades when the underlying causes are properly addressed.
