Waterproofing Contractors in Queens
Heavy rainstorms in Queens bring flash flood warnings; for property owners, that means stress about basement leaks, roof damage, and water intrusion. That's where partnering with waterproofing contractors in Queens, NY helps. At 5 Boro Construction Services, we perform proactive inspections to identify potential problems before they escalate or a weather event turns them into costly repairs. As experienced waterproofing contractors in New York, we fix minor leaks and cracks while strengthening your property before the next major storm arrives.
Foundation & Below-Grade Waterproofing
Queens’ dense clay soil and low-lying areas may trap water. Our basement waterproofing keeps the lower levels dry. Our experts ensure that moisture stays out with exterior waterproofing, wrapping below-grade walls in a heavy-duty protective barrier.
In areas with high water tables, custom interior and exterior drainage systems using gravel-bedded French drains and reliable sump pumps are installed. We also set up thick vapor barriers along floors and crawlspaces to stop humidity from rising.
Roof & Exterior Protection from Rain and Snow
From harsh winter freeze-thaw cycles to strong coastal winds, buildings in Queens are constantly exposed to the elements. Roof waterproofing teams at 5 Boro Construction Services apply seamless liquid membrane systems to flat roofs to prevent water pooling.
Our experts use breathable waterproof coatings on exterior surfaces, to protect buildings from rain, moisture penetration, and long-term weather-related deterioration. All this, while allowing trapped moisture to escape
Commercial Waterproofing & Maintenance
Property managers and business owners throughout Queens rely on us for comprehensive commercial waterproofing solutions. We work on a wide range of properties, including warehouses and retail locations along Queens Boulevard, and multi-family residential complexes.

White powder is efflorescence. Groundwater that seeps through concrete leaves mineral salts as it evaporates. While crack sealing fixes localized gaps, heavy efflorescence could be a sign of a deeper problem. You might need a vapor barrier or an interior drainage system to prevent moisture penetration.
If the original roof deck is structurally sound and free of trapped moisture, liquid waterproofing is fine. High-grade liquid roof waterproofing membrane over the top creates a brand-new, seamless shield without the high cost of a total roof tear-off.
Commercial buildings have much larger surface areas, flat roof configurations that potentially collect massive amounts of water, and strict local NYC building codes to follow. The materials used must be industrial-grade to handle building movement, heavy foot traffic, and intense weather exposure.
