Complete Waterproofing Services for NYC Properties
Basement Waterproofing
We address damp walls, basement leaks, cracks, seepage, and moisture entering through floors or foundation surfaces. Interior and exterior basement waterproofing options are recommended based on the source and condition of the water problem.
Roof Waterproofing
Cracks, damaged coatings, open seams, and worn roofing surfaces can allow water to enter the building. Our roof waterproofing services help seal vulnerable areas and improve protection against rain and standing water.
Exterior Waterproofing
Exterior walls can absorb moisture through cracks, joints, porous surfaces, and damaged coatings. We apply suitable sealants, membranes, and protective systems to help reduce water penetration and weather-related deterioration.
Foundation Waterproofing
Foundation cracks and moisture exposure can lead to leaks, damp interiors, and surface deterioration. Our foundation waterproofing services focus on sealing affected areas and improving protection around below-grade walls and structural surfaces.
Thoroseal Waterproofing
Thoroseal is a cement-based waterproof coating used on concrete, masonry, and compatible surfaces. Proper preparation and application can help reduce moisture penetration in basements, walls, foundations, and other masonry areas.
Thorocoat Waterproofing
Thorocoat systems provide protective coatings for concrete, masonry, stucco, and exterior wall surfaces. The appropriate product and application method depend on the existing material, exposure, and condition of the property.

Waterproofing Services FAQs
How much does professional waterproofing cost in NYC?
On average, NYC homeowners spend between $3,500 and $8,500 on basement or exterior waterproofing. Costs in boroughs like Brooklyn or Manhattan are often higher due to dense building structures, manual excavation requirements, and strict local Department of Buildings (DOB) regulations. We provide free on-site inspections to give you an accurate, fixed-price quote based on your specific property needs.
Do I need a permit for waterproofing services in New York City?
Most minor interior repairs, such as foundation crack injections, do not require a permit. However, major projects involving exterior excavation, structural foundation work, or new drainage connections to city sewers often require a permit from the NYC Department of Buildings (DOB). As a licensed NYC Home Improvement Contractor, we handle all necessary filings and safety compliance to ensure your project meets local building codes.
What is the best waterproofing method for NYC brownstones and basements?
For the tight footprints common in NYC brownstones, Interior French Drain Systems combined with a heavy-duty sump pump are often the most effective and cost-efficient solution. This method manages hydrostatic pressure without requiring exterior excavation in narrow alleyways. For flat-roofed buildings, we recommend liquid-applied silicone membranes which provide a seamless, UV-resistant barrier against the city’s heavy rain and snow cycles.
Is interior or exterior waterproofing better?
The right method depends on the source of the water and the condition of the property. Exterior waterproofing addresses moisture before it enters the building, while interior systems may help manage leaks and dampness from inside.
How much do waterproofing services cost in NYC?
Waterproofing costs depend on the affected area, source of the leak, surface condition, accessibility, preparation requirements, and waterproofing system. A property assessment is usually needed before an accurate estimate can be provided.
