Waterproofing Old Westbury NY: Precision Solutions for Luxury Living

Old Westbury, NY, is home to some of Long Island’s most refined and architecturally impressive residences. With expansive estates, rolling landscapes, and high-end construction, these homes require meticulous basement waterproofing to preserve their value and structural integrity. At A.M. Shield, we provide expert waterproofing solutions designed to handle the complex environmental and design factors that define Old Westbury living—ensuring your basement remains dry, healthy, and protected for decades to come.

Why Waterproofing Matters in Old Westbury

Despite Old Westbury’s elevated terrain, the area’s rich, moisture-retaining soil and extensive landscaping create ideal conditions for water accumulation around foundations. Combined with seasonal rain, snowmelt, and expansive irrigation systems typical of large estates, these environmental factors place continuous stress on basement walls and slabs—especially in homes with finished lower levels or below-grade mechanical rooms.

Many Old Westbury residences also feature intricate architectural details, luxury materials, and sensitive systems such as climate-controlled wine cellars, gyms, or home theaters in the basement. Even minimal water infiltration in these spaces can cause:

Costly damage to flooring, millwork, or electronics
Mold growth behind walls or under insulation
Increased humidity affecting comfort and indoor air quality
Long-term structural weakening from unseen foundation stress

Basement waterproofing in Old Westbury is not just about leak prevention—it’s a crucial step in protecting the performance, health, and long-term value of your home. Whether you’re managing an existing water issue or upgrading outdated systems, investing in professional waterproofing ensures peace of mind.

At A.M. Shield, we tailor our waterproofing services to match the complexity and value of Old Westbury properties. Whether your home is a restored classic or a modern custom build, we offer comprehensive solutions that integrate seamlessly into your structure—without compromising design or function.

Interior Waterproofing Systems

For homes experiencing moisture seepage or elevated humidity, our interior systems provide discreet, effective protection:

Subfloor perimeter drainage channels capture water entering through foundation walls or rising from beneath the slab.
High-performance sump pumps, often paired with battery backup systems, ensure reliable water evacuation even during power outages.
Epoxy and polyurethane crack injection seal foundation fissures while preserving structural strength.

These systems are particularly well-suited for finished basements, where early intervention prevents costly interior damage.

Exterior Waterproofing

When exterior conditions are the source of ongoing pressure or saturation, we offer long-term solutions that address the problem at its source:

Excavation and application of seamless waterproof membranes create a durable external barrier.
French drain installation and grading correction help redirect water away from the structure.
Custom access points and clean-outs are available for properties with extensive landscaping or limited accessibility.

These systems are particularly well-suited for finished basements, where early intervention prevents costly interior damage.

Crawl Space Encapsulation

If your home includes a crawl space, we provide full encapsulation services to eliminate moisture, prevent mold, and protect your substructure. Our process includes:

Vapor barrier installation
Drainage matting and sump integration
Optional dehumidifiers for complete air management

This is especially valuable in Old Westbury homes with hybrid basement/crawl configurations or vintage construction elements.
