Above-Grade Waterproofing for Rochester Offices, Hospitals, Campuses & Lofts
Commercial Waterproofing Contractors in Rochester, NY
Rochester buildings spend much of the year under snow. Lake-effect storms off Lake Ontario load roofs, ledges and parapets, and every thaw sends meltwater into open joints, cracked mortar and loose flashing. When temperatures drop again, that water freezes and widens the opening. Spring and summer thunderstorms bring heavy rain, and humid summers age the sealants and coatings that are supposed to keep the building dry.
Presto Restoration has more than 25 years of experience in above-grade commercial waterproofing. In Rochester, our crews reseal expansion joints and window perimeters, coat walls and parapets with silicone and elastomeric systems and protect masonry with breathable repellents on office buildings, hospitals and university buildings, converted factory lofts and apartment communities. We also make our own restoration products, including Glass Defender for glass and Leach Stop for precast concrete.
OUR COMMERCIAL WATERPROOFING SERVICES IN ROCHESTER
We handle every kind of above-grade waterproofing on Rochester commercial buildings, from a single leaking window to a complete envelope program.
Core Waterproofing Services
Expansion and control joints let buildings move through Rochester’s temperature swings. As the sealant ages, it tears and lets meltwater into the structure. We remove failed joint materials, rebuild damaged edges and install sealants or preformed systems sized for the movement, and we rout and seal active cracks.
Window perimeters cause many leaks in Rochester buildings. Freeze-thaw and wind-driven rain crack the sealant or pull it from the frame. We replace perimeter seals, reseal mullion joints and fix gaskets, and stained glass can be restored and protected with Glass Defender.
Ledges, parapets, canopies and balconies collect heavy snow and meltwater, and freeze-thaw cracks them open. We apply high-solids silicone coatings that tolerate ponding water, stay flexible in deep cold and resist UV.
Older Rochester office buildings often rely on dry glazing gaskets that shrink with age, letting rain and meltwater into the frame. Wet glazing adds a continuous silicone seal between glass and frame, stopping leaks without replacing the windows.
Concrete, stucco and EIFS walls crack after years of freeze-thaw, and every crack lets water in. Elastomeric coatings span the cracks and flex as the wall moves, applied at full thickness after larger cracks are repaired.
Brick, block, stone and precast absorb meltwater that freezes and breaks them apart. Breathable water repellents cut that absorption while letting moisture escape, applied after cracks and joints are repaired.
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 that leave white streaks as water dries, and winter salt makes it worse. Leach Stop is our treatment designed to reduce this. We clean 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. We replace failed sealants with products made for metal movement and reseal every lap and fastener.

Rochester Commercial Waterproofing FAQs
How often should sealants be replaced on a Rochester building?
Most commercial sealants in the Rochester area last about 10 to 15 years. Joints on sunny or wind-exposed 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 occupants 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. Historic brick usually needs a breathable repellent.
How do I know if waterproofing can wait another year?
Leaks when snow melts, damp walls or split caulking are reasons to act now, because each winter refreezes the water already in the wall. If sealants are still flexible and nothing leaks, planned replacement over the next few seasons is usually fine.
Can waterproofing work be done in a Rochester winter?
Most sealants and coatings need about 40 degrees Fahrenheit or warmer to cure, so the main season runs from spring through fall, with emergency repairs possible in winter.
