Brookville Basement Waterproofing Company
At Diamond Masonry & Waterproofing LLC, we specialize in the unique challenges that Long Island homeowners face. The high water table and clay soil conditions here create specific problems that require local expertise.
We’ve seen every type of basement water issue common to older homes in Brookville and surrounding areas. From foundation cracks that develop over decades to hydrostatic pressure problems that generic solutions can’t handle.
Our approach combines proven waterproofing techniques with materials designed for our local conditions. We’re not a national franchise following a one-size-fits-all playbook – we’re local contractors who understand what actually works in this area.

Basement Waterproofing Process
First, we inspect your basement thoroughly to identify all water entry points and assess the extent of any existing damage. We check foundation walls, floor joints, window wells, and any previous repair attempts.
Next, we develop a comprehensive plan that addresses both immediate water problems and long-term prevention. This might include interior drainage systems, exterior excavation and sealing, crack injection, or a combination of approaches depending on your specific situation.
During the work, we protect your property and minimize disruption to your daily routine. We explain each step as we go and clean up completely when finished. You’ll receive documentation of all work performed and materials used – important for warranty coverage and future home sales.

Complete Waterproofing Solutions
Our basement waterproofing services include both interior and exterior solutions tailored to your home’s specific needs. Interior work focuses on managing water that’s already entered through drainage systems, sump pumps, and wall treatments.
Exterior waterproofing addresses the source by excavating around foundation walls, applying professional-grade sealers, and installing proper drainage systems. We also handle foundation crack repair using injection techniques that create permanent seals.
For homes in Brookville’s older neighborhoods, we often recommend a combination approach. The clay soil common here can shift over time, creating new stress points. Our comprehensive solutions account for these local conditions and provide long-term protection that holds up through seasonal changes and severe weather events.
