Professional Waterproofing on Long Island

Basement, crawl space, foundation, and exterior waterproofing solutions that keep water out — permanently. Serving Long Island homeowners and businesses.

Why It Matters

Stop Water Intrusion Before It Destroys Your Home

Water is the single most destructive force a home faces over time. A damp basement, a wet crawl space, or a cracked foundation may seem minor at first — but left untreated, water intrusion leads to structural deterioration, mold growth, compromised air quality, and costly repairs that dwarf the cost of prevention.

Disaster Cleanup Services, Inc. provides comprehensive waterproofing solutions for Long Island homes and businesses. Our certified technicians assess every entry point — from foundation cracks to hydrostatic pressure — and implement the right system to keep your property permanently dry.

The Consequences

What Happens When Water Gets In

Unchecked water intrusion doesn't stay contained. It migrates through concrete, saturates insulation, rots wood framing, and creates the warm, damp conditions mold needs to thrive. Over time, hydrostatic pressure can bow and crack foundation walls, compromising the structural integrity of your entire home.

Foundation Damage

Hydrostatic pressure from saturated soil pushes against foundation walls, causing cracks, bowing, and eventual structural failure if not addressed.

Mold & Mildew Growth

Moisture levels above 60% create ideal conditions for mold. A wet basement or crawl space can seed mold colonies that spread throughout the entire structure.

Wood Rot & Deterioration

Framing, joists, and sill plates in contact with moisture will rot over time, weakening the structural support of floors and walls above.

Poor Indoor Air Quality

Up to 50% of the air in your living space comes from your basement or crawl space. Moisture, mold spores, and radon travel upward through the stack effect.

What We Do

Our Waterproofing Services

Basement Waterproofing

Interior drainage systems, sump pump installation, wall crack injection, and vapor barriers work together to keep your basement permanently dry regardless of groundwater conditions.

Crawl Space Encapsulation

We seal crawl spaces with heavy-duty vapor barriers, install dehumidifiers, and address all moisture entry points — eliminating the damp conditions that breed mold and rot.

Foundation Waterproofing

Crack injection with polyurethane or epoxy seals active leaks in poured concrete and block foundations. We also apply waterproofing membranes to exterior foundation walls.

Exterior Waterproofing

Full exterior excavation and waterproofing membrane application addresses water at its source — before it ever reaches your foundation walls. The most comprehensive solution available.

Sump Pump Systems

We install, replace, and service primary and battery backup sump pump systems to ensure water is actively removed from your basement even during power outages.

French Drain Installation

Interior and exterior French drain systems intercept groundwater and redirect it away from your foundation, relieving hydrostatic pressure before it causes damage.
