Basement Waterproofing Company Glen Head
Diamond Masonry & Waterproofing has been solving water problems for Glen Head homeowners who need real solutions, not temporary patches. We understand how Long Island’s clay soil and seasonal water table changes create the perfect storm for basement water issues.
You’re not getting a fly-by-night operation or someone learning on your dime. We’ve seen every type of water intrusion problem this area throws at basements, from foundation wall seepage to hydrostatic pressure issues.
Our approach works because we treat the cause, not just the symptoms. Licensed, insured, and focused on permanent results that protect your investment.

Waterproofing Process Glen Head
First, we inspect your basement to identify exactly where water is entering and why. No guesswork. We look at your foundation walls, floor joints, window wells, and exterior drainage patterns. You’ll know what’s causing your water problem before we recommend any solution.
Next, we create a waterproofing plan that addresses your specific situation. This might involve interior basement waterproofing with drainage systems and sump pumps, exterior basement waterproofing with membrane application, or both. We explain what needs to happen and why.
Then we execute the plan using professional-grade materials designed for Long Island conditions. Our basement waterproofing services include proper preparation, quality installation, and testing to ensure everything works before we consider the job complete. You’ll see the difference immediately when the next storm hits.

Basement Sealing Services Glen Head
You get a comprehensive basement waterproofing solution tailored to your home’s specific water challenges. This includes foundation wall sealing, proper drainage installation, and moisture control systems that work together to keep water out permanently.
Our waterproofing services cover both interior and exterior approaches because Glen Head’s soil conditions often require multiple lines of defense. Interior basement waterproofing handles water that’s already penetrating, while exterior solutions prevent water from reaching your foundation in the first place.
Every installation includes quality basement waterproofing materials that can handle Long Island’s weather extremes. We’re not using basement sealer products you can buy at the hardware store – this is professional-grade waterproofing designed to last decades, not seasons.
