Above-Grade Waterproofing for Buffalo Office Towers, Medical Buildings & Lofts
Commercial Waterproofing Contractors in Buffalo, NY
Few cities put a building envelope through more than Buffalo. Lake-effect storms off Lake Erie bury roofs, ledges and parapets, wind off the water pushes snow and rain into joints and window frames, and every thaw sends meltwater into any opening it can find. When the cold returns, that water freezes and widens the gap. Summer storms bring heavy rain, and humid heat ages the sealants and coatings meant to keep it all out.
Presto Restoration has more than 25 years of experience in above-grade commercial waterproofing. In Buffalo, our crews reseal expansion joints, window perimeters and curtain walls, coat parapets and walls with silicone and elastomeric systems and protect masonry with breathable repellents on office towers, medical and research buildings, converted lofts, university buildings 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 BUFFALO
We handle every kind of above-grade waterproofing on Buffalo commercial buildings, from one leaking window to a full envelope program.
Core Waterproofing Services
Expansion and control joints let concrete and masonry buildings move through Buffalo’s temperature swings. As sealant ages, it tears and lets meltwater 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 are behind many leaks in Buffalo offices and apartments. Wind off the lake and years of freeze-thaw 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, setbacks and balconies hold 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.
Many older Buffalo office buildings rely on dry glazing gaskets that have shrunk and hardened, letting wind-driven rain 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, sandstone, block 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 road 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.

Buffalo Commercial Waterproofing FAQs
How often should sealants be replaced on a Buffalo building?
Most commercial sealants in western New York last about 10 to 15 years. Joints on lake-facing or sunny 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, terra cotta and sandstone usually need a breathable repellent.
How do I know if waterproofing can wait another year?
Leaks after storms, damp walls in the spring thaw 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 Buffalo 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.
