Protecting New York Properties from Water Damage—One Home at a Time
Water damage can silently destroy your property’s structure, leading to costly repairs and health hazards like mold. At Waterproofing Experts NY, we specialize in safeguarding homes and commercial buildings with proven, long-lasting waterproofing solutions tailored to New York’s unique climate and building styles.
Why Waterproofing Is Essential in NYC
Whether you’re in coastal Long Island or a brownstone in Brooklyn, water infiltration is a serious risk. From aging basements to flat rooftops and unpredictable weather, homes across the boroughs face constant pressure from moisture.
Without proper waterproofing, you could face:
- Foundation cracks and settlement
- Basement flooding and mold growth
- Damaged insulation, drywall, and flooring
- Decreased property value
Our professional waterproofing services offer protection, peace of mind, and long-term savings.
Our Waterproofing Services
We offer a full range of residential and commercial waterproofing services. Whether it’s preventing water intrusion or fixing an existing issue, we’ve got you covered.
🏠 Basement Waterproofing
Keep your basement dry year-round. We install interior drainage systems, sump pumps, vapor barriers, and seal cracks to prevent flooding and mold growth.
🧱 Foundation Waterproofing
We apply waterproof membranes, sealants, and drainage systems to protect your foundation from moisture intrusion that can lead to structural damage.
🛖 Crawl Space Waterproofing
Avoid standing water and humidity buildup. We encapsulate crawl spaces with vapor barriers and dehumidification systems to keep your air and structure clean.
☔ Roof Waterproofing
Flat roofs are prone to leaks. We provide waterproof roof coatings, membrane installations, and flashing repairs to keep water out—especially vital in NYC’s heavy rain seasons.
🧼 Interior Waterproofing
When external access is limited, our interior solutions protect your basement walls and floors using drain tile systems, sealants, and wall vapor barriers.
🌧️ Exterior Waterproofing
We excavate and waterproof exterior walls with membranes and proper grading. Best for buildings with recurring water intrusion problems.
💧 Crack Repair & Sealants
We seal wall and floor cracks using epoxy injection, polyurethane, and hydrophobic sealants to prevent leaks and future widening.
🕳️ Deck & Balcony Waterproofing
From French drains to sump pumps and downspout extensions, we design drainage solutions that move water away from your property efficiently.
