Above-Grade Waterproofing for Newark Office Towers, Universities & Residential Buildings
Commercial Waterproofing Contractors in Newark, NJ
Water reaches Newark buildings in every season. A nor’easter can pound a curtain wall with rain for a full day, summer storms overwhelm roof drains and plazas, and the remnants of tropical systems have caused serious flooding around Essex County. Over the winter, water already inside a crack or joint freezes and enlarges it, and summer heat steadily ages the sealants that keep it out.
Above-grade commercial waterproofing has been Presto Restoration’s specialty for more than 25 years. Our Newark crews reseal expansion joints, window perimeters and curtain walls, coat parapets and walls with silicone and elastomeric systems and treat masonry with breathable repellents on towers, campus and medical buildings and apartment communities. Our own restoration products, such as Glass Defender for glass and Leach Stop for precast concrete, round out the work.
OUR COMMERCIAL WATERPROOFING SERVICES IN NEWARK
We handle every kind of above-grade waterproofing on Newark commercial buildings, from a single leaking window to a full envelope program.
Core Waterproofing Services
Expansion and control joints let Newark’s concrete and masonry buildings move through hot summers and freezing winters. When the sealant inside them hardens and tears, rain and snowmelt run into the structure. We remove failed joint materials, rebuild damaged edges and install sealants or preformed joint systems sized for the movement, and we rout and seal active cracks.
Window perimeters cause many of the leaks we see in Newark offices and apartments. The sealant around each frame takes years of sun and storm-driven rain until it splits or separates. We replace perimeter seals, reseal mullion joints and repair gaskets, and stained glass can be restored and protected with Glass Defender.
Ledges, parapets, setbacks and balconies hold water and snow, and freeze-thaw cracks them open. We apply high-solids silicone coatings that tolerate ponding water, stay flexible in cold weather and resist UV, often over existing surfaces.
Many older Newark office towers rely on dry gaskets that have shrunk and hardened with age, letting rain into the frame during every storm. Wet glazing adds a continuous silicone seal between glass and frame, stopping leaks and extending the curtain wall’s life without replacement.
Concrete, stucco and EIFS walls develop hairline cracks as they age, and each crack lets water in. Elastomeric coatings span those cracks and flex as the wall moves. We repair larger cracks first and apply the coating at full thickness.
Brick, block, stone and precast soak up water that freezes in winter and keeps walls damp in summer. Breathable water repellents cut that absorption while letting moisture escape, and we repair cracks and joints before treating.
Specialized Restoration-Waterproofing
Beyond sealing, Presto restores the glass, metal, stone and concrete beneath, using products we make in-house, so cleaning, repair and waterproofing happen in one project.
Precast panels leach natural salts when water moves through them, leaving white streaks as they dry, and winter salt makes it worse. Leach Stop is our treatment designed to reduce this. We clean off deposits, treat the panels and reseal the joints.
Metal panels, Alucobond cladding, coping and curtain wall frames rely on sealant at every joint, and metal moves sharply between seasons. When those joints fail, water gets behind the panels. We replace the sealants with products made for metal movement and reseal every lap and transition.

Newark Commercial Waterproofing FAQs
How often should sealants be replaced on a Newark building?
Most commercial sealants in North Jersey last about 10 to 15 years. Joints on sunny or storm-facing elevations usually fail first, so a yearly look is worthwhile.
What is the difference between waterproofing and water damage repair?
Waterproofing stops water at the exterior. Water damage repair fixes what water has already harmed inside. We focus on stopping the water so interior repairs do not have to be repeated.
Can waterproofing be done while the building is occupied?
Yes. Almost all of our work is done from the outside, so tenants stay in place, and noisy tasks are scheduled around operations.
What is the difference between elastomeric coatings and water repellents?
Elastomeric coatings form a flexible film that bridges cracks and changes the wall’s look. Water repellents soak into masonry and block water invisibly. Older masonry usually needs a breathable repellent.
How do I know if waterproofing can wait another year?
Leaking during storms, damp walls or caulking that has split are signs to act now, since each storm and freeze makes things worse. Sealant that is still soft, bonded and leak-free can usually be scheduled for replacement over the next few years.
Can waterproofing work be done in a New Jersey winter?
Most sealants and coatings need about 40 degrees Fahrenheit or warmer to cure, so the main season runs spring through late fall, with emergency repairs possible in winter.
