We Fix Foundations the Right Way

We at Diamond Masonry & Waterproofing have been handling foundation and basement issues throughout Baywood and Long Island for years. We understand how the local soil conditions and seasonal changes affect your home’s foundation.

We’re licensed, insured, and focused on permanent solutions rather than quick fixes that fail in a few years. When we repair foundation cracks, we use professional-grade injection methods that actually stop water infiltration.

You’re dealing with contractors who show up when scheduled, explain what needs to happen, and stand behind our work with real warranties.

Foundation Crack Injection Process

Here's Exactly What We Do

First, we inspect your foundation cracks to determine the type of repair needed and identify any underlying issues. Not all cracks are the same, and the repair method depends on whether it’s structural or just settling.

We clean and prepare the crack, then inject either polyurethane or epoxy depending on whether it’s an active leak or structural repair. The injection fills the entire crack from inside the wall, creating a permanent seal that’s actually stronger than the surrounding concrete.

After the injection cures, we apply exterior sealant if needed and test the repair. You get a detailed explanation of what was done and how to monitor the area going forward. The whole process usually takes a few hours, and you can see the results immediately.

Basement Wall Crack Repair

What's Included in Your Foundation Repair

You get a complete assessment of all visible cracks and potential problem areas, not just the obvious ones. We check for structural issues, water infiltration patterns, and any signs of ongoing foundation movement.

The repair includes professional crack injection using commercial-grade materials, exterior sealing where accessible, and moisture control recommendations. We also identify any drainage issues that might be contributing to the problem.

Every job comes with a detailed warranty covering both materials and workmanship. You receive documentation of what was repaired and maintenance recommendations to prevent future issues. If you’re dealing with multiple cracks or basement waterproofing needs, we handle it all as one coordinated project.

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

Any crack wider than a quarter-inch, cracks that are actively leaking water, or cracks that have grown since you first noticed them need professional attention. Horizontal cracks are always serious and indicate structural pressure that won’t resolve on its own. Even smaller cracks can allow water infiltration that leads to bigger problems over time. If you can see daylight through a crack or feel air movement, that’s definitely a repair situation. When in doubt, get it looked at – foundation problems don’t improve by waiting.

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

Crack injection actually fills the entire crack through the wall thickness, creating a permanent structural repair. Outside sealing only covers the surface and typically fails within a few years as the foundation moves with seasonal changes. Injection uses polyurethane or epoxy that bonds with the concrete and remains flexible, so it moves with your foundation rather than cracking apart. Surface sealants can’t handle the pressure from water infiltration or foundation settlement. Professional injection is more expensive upfront but eliminates the need for repeated repairs.

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

Most crack injection repairs take 2-4 hours depending on the number and size of cracks being addressed. The work is done from inside your basement, so there’s no excavation or major disruption to your yard or landscaping. You’ll need to clear the area around the cracks and may hear some drilling noise during preparation, but it’s not a multi-day construction project. The injection material cures quickly, usually within a few hours, though we recommend waiting 24 hours before testing with water. You can use your basement normally right after we finish.

Will the cracks come back after injection repair?

Properly done crack injection creates a repair that’s stronger than the surrounding concrete, so the same crack won’t reopen. However, new cracks can develop if there are ongoing foundation movement or drainage issues that aren’t addressed. That’s why we evaluate the underlying causes, not just treat the visible symptoms. Our injection repairs come with warranties covering the specific cracks we treat. If your foundation continues settling or you have water pressure issues, those need to be addressed separately to prevent new problems in different areas.

How much does foundation crack repair cost in Baywood?

Foundation crack injection typically runs $300-800 per crack depending on length, width, and accessibility, but every situation is different. Multiple cracks or basement waterproofing needs change the scope significantly. We provide written estimates after seeing the actual conditions – photos can’t tell the whole story with foundation work. The cost depends on whether it’s structural repair with epoxy or water infiltration repair with polyurethane, plus any prep work needed. Getting multiple quotes makes sense, but focus on contractors who actually explain what they’re doing and why.

Do you handle emergency foundation repairs?

Yes, we respond to emergency situations like active water infiltration, new large cracks, or obvious structural issues that develop suddenly. Foundation emergencies usually involve water coming through cracks during storms or cracks that appear quickly, which can indicate serious structural movement. We can often provide temporary water control measures while scheduling permanent repairs. However, most foundation issues develop over time and aren’t true emergencies – it’s better to address problems before they become urgent situations that require emergency pricing and rushed scheduling.
