Your Foundation Problems Actually Get Solved

You know that sinking feeling when you spot a crack in your foundation wall. Is it serious? Will it get worse? How much will this cost you?

Here’s what happens when foundation cracks get properly fixed. The water stops seeping in during heavy rains. You stop worrying every time you walk past that wall. Your basement stays dry, and you can actually use the space without fear of damage to your belongings.

Most importantly, you protect what’s probably your biggest investment. Foundation problems don’t fix themselves, and they definitely don’t get cheaper over time. When you address cracks early with professional crack injection and proper sealing, you’re preventing the kind of major structural issues that can cost tens of thousands later.

Diamond Masonry Valley Stream Contractors

We Know Long Island Foundations

We’ve been handling foundation repairs throughout Valley Stream and Long Island for years. We understand exactly what causes foundation problems in this area – the clay soil, the freeze-thaw cycles, the way water moves around older home foundations.

We’re not the guys who show up and immediately try to sell you a complete foundation replacement. We assess what’s actually wrong, explain what needs to be fixed, and give you honest options. Most foundation cracks can be permanently repaired with proper injection techniques and waterproofing – no need to tear apart your entire basement.

Foundation Crack Repair Process

Here's Exactly How We Fix It

First, we inspect your foundation to determine what type of cracks you’re dealing with and what’s causing them. Not all cracks are the same, and the repair method depends on whether you’re dealing with settling, water pressure, or structural movement.

For most basement wall cracks, we use professional-grade polyurethane or epoxy injection. We clean out the crack, install injection ports, and pump the material in under pressure. This creates a permanent seal that’s actually stronger than the surrounding concrete. The whole process usually takes a few hours, not days.

If water infiltration is an issue, we also address the waterproofing side. This might include exterior drainage work or interior waterproofing systems, depending on what your specific situation needs. We explain everything upfront so you know exactly what we’re doing and why.

More Than Just Crack Repair

Foundation crack repair is just one part of keeping your basement dry and your foundation solid. We also handle basement wall crack repair, foundation leak repair, and complete waterproofing systems when needed.

Valley Stream homes face unique challenges with Long Island’s soil conditions and weather patterns. We’ve seen everything from minor hairline cracks to significant structural issues, and we know which problems need immediate attention versus which ones you can monitor over time.

Our concrete crack repair work comes with warranties because we use the right materials and techniques. We’re not patching things up with hardware store caulk – we’re creating permanent solutions that address both the crack itself and the underlying water infiltration issues.

How do I know if my foundation crack is serious?

Most foundation cracks fall into two categories: cosmetic settling cracks and structural concerns. Hairline cracks less than 1/8 inch wide are usually settling and can be monitored. However, any crack that’s allowing water infiltration needs immediate attention, regardless of size. Horizontal cracks, cracks wider than 1/4 inch, or cracks that are growing should be evaluated by a professional right away. In Valley Stream’s clay soil conditions, even small cracks can become major problems during freeze-thaw cycles, so it’s better to address them early than wait and see what happens.

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

Surface sealing with caulk or concrete crack filler is a temporary fix that usually fails within a year or two. Professional crack injection actually fills the entire crack from the inside out using polyurethane or epoxy under pressure. This creates a permanent bond that’s stronger than the surrounding concrete and flexible enough to handle normal foundation movement. The injection method also stops water infiltration completely, while surface sealing often just redirects water to find another way in. It costs more upfront, but it’s the difference between fixing the problem once versus dealing with it repeatedly.

How long does foundation crack repair take?

Most basement crack repair jobs take between 2-4 hours, depending on the number and size of cracks. The actual injection process is relatively quick, but we spend time properly preparing the crack and ensuring the material cures correctly. You can usually use your basement the same day, though we recommend waiting 24 hours before putting any water pressure on the repaired area. If we’re also doing waterproofing work or addressing multiple foundation issues, the timeline extends accordingly, but we’ll give you a clear schedule upfront.

Will fixing foundation cracks prevent future problems?

Proper crack injection creates a permanent seal for that specific crack, but it doesn’t prevent new cracks from potentially developing elsewhere. However, by stopping water infiltration and addressing drainage issues around your foundation, crack repair significantly reduces the conditions that cause foundation problems to worsen. In Long Island’s soil conditions, the key is addressing both the immediate crack and any underlying water management issues. We often recommend monitoring your foundation annually and addressing minor issues before they become major problems.

How much does foundation crack repair cost in Valley Stream?

Foundation crack repair costs depend on the number of cracks, their size and location, and whether additional waterproofing work is needed. Simple crack injection typically runs several hundred dollars per crack, while more complex repairs involving multiple cracks or structural concerns cost more. The good news is that professional crack repair is almost always much less expensive than dealing with ongoing water damage or major foundation replacement later. We provide upfront estimates after evaluating your specific situation, so you know exactly what you’re paying for before any work begins.

Do you warranty your foundation repair work?

Yes, we warranty our crack injection work because we use professional-grade materials and proven techniques. The specific warranty terms depend on the type of repair and materials used, but we stand behind our work. We also provide guidance on maintaining your foundation and drainage systems to prevent future issues. Keep in mind that warranties cover the repair work itself – they don’t prevent new cracks from potentially developing in other areas of your foundation due to normal settling or external factors like major drainage changes around your property.
