We Actually Know Foundation Repair

Diamond Masonry & Waterproofing LLC combines two critical skills that most contractors handle separately – masonry expertise and waterproofing knowledge. That matters because foundation cracks aren’t just waterproofing problems or just structural problems.

We have been serving Centerport and Long Island homeowners who need foundation issues resolved permanently, not temporarily patched. Our team understands how Long Island’s soil conditions and coastal climate affect foundation integrity.

When you’re dealing with foundation cracks, you need contractors who can properly diagnose whether you’re looking at settling, water pressure, or structural issues – and then fix it accordingly.

Foundation Crack Repair Process Centerport

Here's Exactly How We Fix It

First, we inspect the entire foundation to understand what’s causing the cracks. Not just the visible damage, but the underlying issue. Is it water pressure, settling, or structural movement? The repair method depends on the root cause.

For most foundation cracks, we use professional crack injection techniques. This involves cleaning out the crack completely, then injecting specialized polyurethane or epoxy materials that bond with the concrete and create a waterproof, flexible seal that moves with your foundation.

We also address any drainage issues that contributed to the problem. Sometimes that means improving exterior drainage, sometimes it means interior waterproofing measures. The goal is making sure the problem doesn’t come back.

You get a detailed explanation of what we found, what we’re doing, and what you can expect long-term. No surprises, no upselling, just straight answers about your foundation.

What's Included in Foundation Crack Repair

You get a complete foundation assessment that identifies all current and potential problem areas. We don’t just fix the crack you called about – we make sure there aren’t other issues developing that could cause problems later.

The repair includes professional crack injection using commercial-grade materials designed for Long Island’s climate conditions. These aren’t hardware store products. We use materials that remain flexible as your foundation experiences normal seasonal movement.

Every job includes addressing drainage issues that may have contributed to the foundation cracks. Sometimes water problems cause foundation issues, and sometimes foundation issues cause water problems. We handle both sides so the repair actually lasts.

You also get clear documentation of the work performed and guidance on maintaining your foundation going forward. We want you to know what to watch for and how to protect your investment.

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

Any crack wider than a hairline or any crack that’s allowing water through needs professional attention. Horizontal cracks are more serious than vertical ones and require immediate assessment. If you can fit a coin in the crack, if it’s growing, or if you see water stains around it, don’t wait. Even small cracks can become big problems quickly, especially with Long Island’s freeze-thaw cycles. The key is getting an honest assessment from someone who understands the difference between normal settling and structural issues.

Will crack injection actually stop water from coming through my foundation?

Professional crack injection creates a waterproof seal when done correctly with the right materials. The polyurethane and epoxy we use are specifically designed to bond with concrete and remain flexible as your foundation moves with temperature changes. However, if water pressure is high due to poor drainage around your foundation, we need to address that too. Just sealing cracks without fixing drainage issues often leads to water finding new ways in. That’s why we look at the whole picture, not just the visible crack.

How long does foundation crack repair take and how much does it cost?

Most foundation crack repairs take 2-4 hours depending on the number and size of cracks. Simple crack injection can often be completed in a single visit. Cost depends on the extent of the damage and what’s causing it, but most homeowners are surprised that professional foundation crack repair costs less than they expected – especially compared to the damage that happens if you wait. We provide written estimates after assessing your specific situation because every foundation is different.

Should I try to fix foundation cracks myself or hire professionals?

DIY foundation crack repair rarely works long-term because most homeowners don’t have access to professional-grade injection equipment and materials. Hardware store crack fillers might stop water temporarily, but they don’t create the flexible, permanent seal that prevents future problems. More importantly, you need to know whether the crack indicates a structural issue that requires more than just sealing. Professional assessment helps you understand what you’re really dealing with and whether a simple repair is sufficient or if you need more extensive work.

What causes foundation cracks in Centerport homes specifically?

Long Island’s soil conditions and coastal climate create specific challenges for foundations. Clay soil expands and contracts with moisture changes, putting pressure on foundation walls. Freeze-thaw cycles cause concrete to expand and contract. Poor drainage around homes, especially older ones, allows water to build up against foundations. Many Centerport homes also deal with high water tables that create hydrostatic pressure against basement walls. Understanding these local conditions is crucial for repairs that actually last rather than just temporarily stopping symptoms.

How do I prevent foundation cracks from happening again after repair?

Proper drainage is the biggest factor in preventing future foundation cracks. Make sure gutters direct water away from your foundation, grade slopes away from your house, and address any areas where water pools near your foundation walls. Regular inspection helps catch small issues before they become big problems. Look for new cracks, water stains, or changes in existing repairs. Most importantly, don’t ignore small cracks hoping they’ll stay small. Early intervention is always less expensive and more effective than waiting until you have major structural issues.
