Hear About Us

Professional Foundation Repair Services
You’ll sleep better knowing water can’t seep through your foundation walls anymore. No more racing to move storage boxes when heavy rains hit Bellport.
Your basement stays dry, even during Long Island’s wettest seasons. The musty smell disappears because moisture can’t find its way in through those cracks that used to keep growing.
Most importantly, you stop worrying about your home’s structural integrity. Foundation crack repair isn’t just about fixing what you can see – it’s about preventing the expensive problems you can’t see yet. When cracks are properly sealed with professional-grade injection materials, they stay sealed.
Bellport Foundation Repair Contractors
Diamond Masonry & Waterproofing LLC has been serving Suffolk County homeowners who need their foundation problems solved permanently, not temporarily patched.
We understand Long Island’s soil conditions and how they affect your home’s foundation. Clay soil, freeze-thaw cycles, and seasonal water table changes create specific challenges that require specific solutions.
You’re not getting a one-size-fits-all approach. Every foundation crack repair we do accounts for your home’s age, construction type, and the unique conditions that caused the problem in the first place.

Foundation Crack Injection Process
First, we inspect your foundation cracks to determine what’s causing them and whether they’re structural or settlement-related. Not all cracks are the same, and the repair approach depends on what we find.
Next, we clean and prepare each crack for injection. This step matters more than most people realize – any debris or loose material has to come out before we can create a permanent seal.
Then we inject professional-grade polyurethane or epoxy material directly into the crack under controlled pressure. This isn’t caulk or surface patching – the injection material penetrates completely through the foundation wall, creating a waterproof barrier that’s actually stronger than the surrounding concrete.
We monitor the injection process to ensure complete fill and proper curing. Once cured, the repair is permanent and warrantied.

Complete Foundation Crack Solutions
Every foundation crack repair includes a thorough assessment of your entire foundation, not just the visible cracks. We check for underlying issues that could cause new cracks later.
You get professional-grade injection materials designed specifically for Long Island’s climate conditions. These aren’t hardware store products – they’re engineered for permanent waterproofing and structural integrity.
We also address drainage issues around the crack area when necessary. Sometimes fixing the crack isn’t enough if water is still pooling against your foundation wall. Our experience with Bellport area homes means we know what to look for and how to prevent future problems.
All work comes with our warranty because we stand behind permanent solutions, not quick fixes.
