Licensed Foundation Repair Contractors

We Actually Know Foundation Repair

Diamond Masonry & Waterproofing has been fixing foundation problems for Glen Cove and Nassau County homeowners who need real solutions, not temporary patches. We’re licensed contractors who understand exactly how Long Island’s clay soil, coastal moisture, and freeze-thaw cycles affect your foundation.

You’re not getting a general handyman who watched a YouTube video. You’re getting masonry and waterproofing specialists who’ve seen every type of foundation crack issue these older Long Island homes develop.

We’ve been serving this area long enough to know which repair methods actually work and which ones fail after the first winter. That experience matters when you’re investing in permanent foundation repairs.

Foundation Crack Injection Process

Here's Exactly How We Fix It

First, we inspect your foundation cracks to determine if they’re structural or settlement-related, because the repair method depends on what’s actually causing the problem. We’re not going to inject cracks that need different treatment.

Next, we clean and prepare the crack properly – this step gets skipped by contractors who don’t know what they’re doing, which is why their repairs fail. We use professional-grade polyurethane or epoxy injection materials depending on whether you’re dealing with active leaks or structural concerns.

The injection process fills the entire crack from inside your foundation wall, not just the surface you can see. We work from the bottom up, ensuring complete penetration and permanent sealing. After the material cures, you have a repair that’s actually stronger than the original concrete and flexible enough to handle normal foundation movement without re-cracking.

Complete Foundation Crack Solutions

What You Get With Our Repairs

Your foundation crack repair includes complete crack injection using materials specifically chosen for your crack type and local conditions. We handle everything from hairline settling cracks to larger structural fissures that need reinforcement.

You get basement wall crack repair that stops water infiltration permanently, not just for a season or two. Our crack injection process works on poured concrete, block foundations, and stone foundations common in Glen Cove’s older homes.

We also address the underlying drainage issues that contribute to foundation problems, because fixing cracks without addressing water management just means you’ll have new cracks forming. You get a comprehensive approach that actually prevents future foundation issues instead of just treating symptoms.

How do I know if my foundation cracks need professional repair?

Any crack wider than a quarter-inch, cracks that are growing, or cracks that leak water need professional attention immediately. Horizontal cracks are always serious and indicate structural pressure that requires expert evaluation. Even smaller cracks should be assessed by a foundation specialist, because what looks minor on the surface might indicate bigger problems within your foundation wall. If you can see daylight through a crack, or if you notice new cracks appearing seasonally, don’t wait – these issues get exponentially more expensive to fix the longer you delay treatment.

What's the difference between crack injection and just sealing cracks?

Surface sealing only covers the visible part of the crack and typically fails within a year or two. Professional crack injection fills the entire crack from inside the foundation wall, creating a permanent repair that’s stronger than the original concrete. We use specialized injection ports and pressure equipment to ensure the repair material penetrates completely through your foundation wall. Surface sealants can’t handle foundation movement and will crack again, while properly injected repairs flex with normal settling without failing. The injection method also addresses water infiltration from inside the wall structure, not just the surface.

How long do foundation crack repairs typically last?

Professional crack injection repairs using quality materials should last the lifetime of your foundation when done correctly. The polyurethane and epoxy materials we use are designed to remain flexible and waterproof for decades, even with normal foundation movement. However, the longevity depends entirely on proper installation and using the right materials for your specific crack type. Cheap surface repairs or DIY solutions typically fail within 1-2 years, which is why many homeowners end up paying for the same repair multiple times before getting it done right.

Can foundation cracks be repaired from inside or outside?

Most foundation cracks are best repaired from the inside using injection methods, which allows us to fill the entire crack structure and create a permanent seal. Interior repairs are also more cost-effective since we don’t need to excavate around your foundation. However, some situations require exterior waterproofing or drainage work in addition to crack repair, especially if you have ongoing water pressure issues. We evaluate each situation individually because the wrong approach just wastes your money and doesn’t solve the underlying problem. Some contractors only do exterior work because it’s more profitable, not because it’s better for your specific situation.

What causes foundation cracks in Glen Cove area homes?

Long Island’s clay soil expands and contracts significantly with moisture changes, putting pressure on foundation walls. Freeze-thaw cycles are particularly hard on foundations, especially in older homes built before modern waterproofing standards. Poor drainage around your foundation, clogged gutters, and settling are also common causes. Many Glen Cove homes were built in the 1940s-1980s when foundation construction standards were different, making them more susceptible to cracking. Coastal moisture exposure also accelerates concrete deterioration over time. Understanding these local factors is crucial for choosing repair methods that will actually work long-term.

Should I be worried about small hairline cracks in my foundation?

Hairline cracks aren’t always emergencies, but they shouldn’t be ignored either. Small cracks can indicate normal settling, but they can also be early signs of foundation movement or water infiltration that will get worse over time. The key is having them evaluated by someone who knows the difference between cosmetic settling cracks and structural issues. Even small cracks can allow water infiltration that leads to bigger problems like mold, efflorescence, or freeze-thaw damage. In Long Island’s climate, any crack that allows water penetration will expand during winter freezing, so early treatment is usually much more cost-effective than waiting.
