Basement Waterproofing Company Brightwaters
Diamond Masonry & Waterproofing LLC specializes in keeping Long Island basements dry. We understand how sandy soil, high water tables, and coastal storms create the perfect conditions for water intrusion.
We’ve seen every type of basement water problem this area throws at homeowners. From foundation cracks that leak during heavy rains to persistent seepage through basement walls.
Our approach combines masonry expertise with proven waterproofing methods. We don’t just patch problems – we solve them permanently using professional-grade materials designed for our local conditions.

Basement Waterproofing Process Brightwaters
First, we inspect your basement thoroughly to identify exactly where water enters and why. We check foundation walls, floor joints, window wells, and exterior drainage around your home.
Next, we create a waterproofing plan that addresses the root causes. This might include exterior basement waterproofing to stop water before it reaches your foundation, interior basement waterproofing systems to manage any moisture that does get through, or both.
Then we install your waterproofing system using professional-grade materials. We seal cracks properly, apply basement wall sealer where needed, and ensure proper drainage. You’ll know exactly what we’re doing and why each step matters for long-term protection.
