When your basement begins showing signs of moisture, damp odors, cracks, or active water seepage, you need a team that brings dependable, permanent solutions—not temporary patchwork. As Greenwich CT’s trusted basement leak repair and waterproofing specialists, we provide homeowners and commercial property owners with long-lasting protection designed to eliminate current water problems and prevent future issues. With decades of technical expertise, advanced diagnostic tools, and proven waterproofing systems, we ensure your basement stays dry, strong, and structurally sound year-round.

Why Basement Leaks Demand Immediate, Professional Attention

Basement water intrusion may start small—a hairline crack, a wet spot after heavy rain, or occasional dampness—but these early indicators often signal deeper issues. Left unresolved, leaks can lead to mold growth, structural deterioration, foundation shifting, damaged flooring, ruined personal belongings, and costly future repairs. Greenwich’s climate, with its heavy seasonal rain, melting snow, and fluctuating groundwater levels, makes professional waterproofing especially critical for local properties.

Our team responds quickly, performs detailed assessments, and addresses the source—not just the symptoms—of water intrusion. We focus on delivering solutions that last the lifetime of your home.

Comprehensive Leak Detection & Waterproofing Solutions

We provide a full range of permanent basement waterproofing and leak repair services tailored specifically for the soil, weather, and foundation conditions in Greenwich CT. Our approach is strategic, thorough, and customized for each property.

1. Crack Repair & Structural Sealing

Foundation cracks are the most common source of water entry. Our specialists use advanced epoxy and polyurethane injection systems to permanently repair horizontal, vertical, and step-cracks. These materials penetrate deep into the crack, bonding the foundation together while creating a flexible, watertight seal that withstands shifting, pressure, and freeze-thaw cycles.

2. Interior Waterproofing Systems

Interior drainage systems are powerful solutions for basements experiencing persistent moisture or active seepage. We install high-capacity drainage channels, sealed sump pump systems, moisture barriers, and vapor-lock wall liners to redirect water away from the basement and out of the home. This method ensures a dry, protected living space even during heavy storms.

3. Exterior Waterproofing & Foundation Protection

Exterior waterproofing is the most comprehensive long-term strategy, stopping water before it reaches the foundation walls. Our team excavates around the structure, applies waterproof membranes, installs drainage boards, upgrades footing drains, and restores soil grading to divert water safely away from your home. This complete system prevents hydrostatic pressure and eliminates exterior-based leaks.

4. Basement Leak Emergency Services

Unexpected water intrusion can cause immediate damage. We offer rapid-response emergency basement leak repair services for floods, sump pump failures, storms, and sudden foundation leaks. Our specialists arrive with the tools, equipment, and expertise to stop the leak, protect your property, and prevent additional damage.

5. Mold, Moisture & Air Quality Protection

A damp basement doesn’t just damage the structure—it threatens indoor air quality. Our moisture control services include dehumidification systems, vapor barriers, and mold prevention strategies that protect your home’s environment, making it cleaner, healthier, and odor-free.
