Other Waterproofing Services in New York City
Water can enter your home or building from more places than just the roof or basement. Cracks in walls, balconies, parapet walls, or concrete surfaces can all let in moisture. These weak spots may seem small, but over time they lead to serious water damage. We offer specialized waterproofing services across New York City, including exterior wall sealing, balcony waterproofing, parapet wall repair, and protective coatings. Whether you live in a brownstone, manage a commercial building, or own a multi-family home—we can help keep every surface dry and protected.
Why You Need Complete Waterproofing
Most homes and buildings have more than one weak area. Water may not just come from the ground or the roof. Rain, snow, and even humidity can damage exterior features. We help stop:
- Water soaking into brick or block walls
- Leaks around balconies, decks, or parapet caps
- Mold forming in walls or ceilings
- Paint peeling or stucco cracking
- Walls crack or peel
- Freeze-thaw damage during NYC winter
- Long-term wear on exposed concrete and masonry
Our goal is to stop water before it becomes a problem—and fix issues fast when they do show up.
Our Specialty Waterproofing Services
Each service is designed to fix a specific area of the home or building. We use strong materials and careful tools to protect exposed surfaces from leaks.
Exterior Wall Waterproofing
Exterior walls take the full impact of NYC’s weather—wind, rain, snow, and heat. Over time, moisture seeps into brick, stucco, or siding. We seal walls to keep water out. This work helps prevent mold, leaks, and freeze damage. It also improves the look of your building’s exterior.
Our Process Includes
- Power washing to remove dirt and mildew
- Checking for cracks, gaps, or missing mortar
- Filling and patching damage
- Applying a breathable waterproof coating or sealant
- Optional repainting with water-resistant finishes
Balcony and Roof Deck Waterproofing
Balconies and roof decks are exposed to sun and rain all year. Cracked tiles, open joints, or worn coatings can let water seep below. This leads to leaks, weak surfaces, and unsafe walking areas. We make sure water flows off the surface and does not collect near doors, walls, or windows.
We Provide
- Surface cleaning and inspection
- Waterproof underlayment installation
- Tile reset or concrete repair
- Application of liquid waterproofing membranes
- Edge sealing and slope correction
- Optional railing sealing or repair
Parapet Wall Waterproofing
Parapet walls are the small walls that rise above roof lines. These often crack or wear down, letting water into the top of your building. This can affect both the roof and inside walls. This protects the upper edge of your structure from leaks and long-term damage.
Our Work Includes
- Checking the cap stones or metal flashing
- Sealing joints, cracks, and caps
- Rebuilding damaged parapet sections
- Applying waterproof coatings or liquid membranes
- Installing new flashing or coping if needed
Concrete Coating & Waterproofing
We apply commercial-grade waterproof coatings to concrete walls, steps, walkways, and driveways. These help block water and reduce surface wear. These coatings protect your surfaces from water, stains, ice, salt, and wear from heavy traffic.
Our Services Include
- Crack filling and surface prep
- Application of penetrating sealers
- Application of epoxy or elastomeric coatings
- Slope correction or surface leveling
- Optional anti-slip additives for safety
