We've Been Fixing Long Island Foundations Right

Diamond Masonry & Waterproofing has been handling foundation and basement issues across Long Island for years. We know how the clay soil here shifts with the seasons and what that does to older foundations.

Most foundation problems we see in Nesconset aren’t actually structural emergencies. They’re maintenance issues that got ignored until water started coming in. We assess every crack properly before recommending repairs.

Our approach combines traditional masonry skills with modern waterproofing techniques. We don’t just patch cracks – we solve the underlying issues that caused them.

Foundation Crack Repair Process

Here's Exactly How We Fix Foundation Cracks

First, we inspect your foundation thoroughly to determine what type of cracks you’re dealing with. Settlement cracks need different treatment than pressure cracks, and we identify the root cause before starting repairs.

For most foundation cracks, we use professional-grade injection methods. This involves cleaning out the crack, injecting specialized sealant under pressure, and ensuring complete penetration through the foundation wall. It’s not a surface patch job.

We also address any drainage issues that might be contributing to the problem. Sometimes the crack repair is only half the solution – you need proper water management around the foundation to prevent future issues.

After repairs cure, we test everything to make sure water infiltration is completely stopped. You get a foundation that performs like it should, not just a temporary fix that fails next season.

Basement Wall Crack Repair

What's Included in Professional Foundation Crack Repair

Every foundation repair starts with a complete assessment of your basement and foundation walls. We identify all existing cracks, check for structural issues, and determine what’s causing the problems.

Crack injection work uses commercial-grade materials designed for Long Island’s soil conditions. We’re not using hardware store caulk or DIY crack fillers. The sealants we inject are engineered to move with your foundation and maintain their seal over time.

We also address the exterior factors that contribute to foundation cracks. This might include improving drainage around your foundation, sealing other potential water entry points, or recommending gutter improvements that prevent water from pooling against your foundation walls.

How do I know if my foundation cracks are serious or just cosmetic?

Cracks wider than a quarter-inch, cracks that are growing, or any crack that lets water through needs professional attention. Horizontal cracks are generally more concerning than vertical ones. If you can see daylight through a crack or if it’s actively leaking during rain, that’s definitely not cosmetic. The location matters too – cracks near corners or where walls meet the foundation slab often indicate settling issues. When in doubt, have it assessed. Most foundation problems are much cheaper to fix early than after they’ve had time to worsen.

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

Professional crack injection stops water infiltration when done correctly. The key is using the right materials and proper injection pressure to ensure the sealant penetrates completely through the foundation wall. DIY crack fillers from hardware stores typically only seal the surface, which is why they fail. We use polyurethane or epoxy injection systems that expand to fill the entire crack and create a permanent water barrier. However, if you have multiple water entry points or drainage issues around your foundation, those need to be addressed too for a complete solution.

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

Most foundation crack repairs take a few hours to complete, depending on how many cracks need attention. The actual injection process is relatively quick, but proper preparation and curing time are important for lasting results. You can usually stay in your home during repairs – we’re working in the basement, not tearing up your living space. The main disruption is keeping the repaired area dry for 24-48 hours while the sealant cures. We schedule around your needs and explain exactly what to expect before starting work.

What causes foundation cracks to form in the first place?

In Nesconset, foundation cracks usually result from soil movement and water pressure. Long Island’s clay soil expands when wet and contracts when dry, putting stress on foundation walls. Poor drainage around the foundation makes this worse by keeping soil saturated. Freeze-thaw cycles also contribute – water gets into small cracks, freezes and expands, making cracks larger. Age is a factor too – older foundations weren’t built with modern waterproofing methods. Sometimes it’s just normal settling, but water management around your foundation is usually the key to preventing future cracks.

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

Small, dry cracks might seem like DIY projects, but foundation repairs usually require professional equipment and materials. Hardware store crack fillers work temporarily at best – they don’t penetrate through the foundation wall or handle the movement that caused the crack originally. Professional injection equipment creates the pressure needed to fill cracks completely, and commercial-grade sealants are designed to flex with your foundation. If water is involved or the crack is larger than hairline, definitely hire professionals. The cost difference between doing it right once and redoing failed DIY repairs makes professional work worth it.

How much does professional foundation crack repair typically cost?

Foundation crack repair costs depend on the number of cracks, their size, and what’s causing them. Simple crack injection typically costs much less than full foundation replacement or major structural work. Most homeowners are surprised that professional crack repair is more affordable than they expected – especially compared to the cost of ignoring the problem until it becomes a major water infiltration or structural issue. We provide upfront pricing after assessing your specific situation. Many foundation repairs pay for themselves by preventing water damage and protecting your home’s value.
