Above-Grade Waterproofing for Modesto Processing Plants, Offices, Hospitals & Historic Buildings
Commercial Waterproofing Contractors in Modesto, CA
Modesto averages only about 13 inches of rain a year, nearly all of it between November and March, so a failed seal can go unnoticed through the dry months and then leak with the first good storm. Long summers of high heat shrink and harden the sealants and coatings that keep water out, and winter tule fog keeps shaded walls wet for days at a time. On large processing and distribution buildings, a single open joint can let water reach product, equipment or offices.
Presto Restoration brings more than 25 years of above-grade commercial waterproofing experience to Modesto. Our crews reseal tilt-up panel joints, expansion joints and window perimeters, wet glaze older storefronts and curtain walls, coat parapets and ledges and treat masonry and concrete with breathable repellents on processing plants, offices, hospitals, school buildings and historic properties. We also manufacture our own restoration products, including Glass Defender for glass and Leach Stop for precast concrete.
OUR COMMERCIAL WATERPROOFING SERVICES IN MODESTO
Our Modesto waterproofing work ranges from a single clinic window that leaks in every storm to resealing a processing plant from roof edge to loading dock.
Core Waterproofing Services
Concrete walls on plants and warehouses are built in panels, and each joint between them opens and closes with the day’s temperature. After enough summers the sealant splits and rain runs through. Our crews strip the old joint, repair chipped panel edges and install sealant or preformed joint material rated for that movement, along with routing and sealing any cracks that are still moving.
On Modesto clinics, offices and apartments, the seal around windows and storefronts is often the first thing to give. We cut out and replace perimeter caulking, reseal mullion joints and repair loose gaskets, and we can clean and protect spotted glass with Glass Defender.
Ledges, parapet caps and canopies spend summer in direct sun and winter holding puddles. A high-solids silicone coating stands up to both and keeps water from soaking into the substrate.
Medical and office buildings from the 1970s and 1980s often still rely on rubber glazing gaskets that have long since shrunk. Wet glazing runs a continuous bead of silicone between glass and frame, which stops the leaks for a fraction of what new windows cost.
Daily heating and cooling opens hairline cracks in stucco and concrete, and fog and rain soak in through them. A full-thickness elastomeric coating, applied after larger cracks are filled, stretches across that movement and keeps the wall dry.
Masonry and concrete drink in sprinkler overspray, fog and rain. A breathable penetrating repellent slows that absorption without sealing in the moisture that is already there, and we apply it only after the wall is repaired.
Specialized Restoration-Waterproofing
We rarely stop at sealing. Presto restores the glass, metal, stone and concrete behind the seal using products from our own line, so one crew finishes the whole job.
White streaks on tilt-up and precast walls usually come from salts carried out of the concrete as rain dries. We clean them off, treat the panels with Leach Stop, our product made for this problem, and reseal the joints between panels.
Every seam in metal panels, copings and storefront framing depends on sealant, and metal in the valley sun grows and shrinks noticeably each day. We replace worn sealant with grades made for metal and reseal laps, seams and fasteners.

Modesto Commercial Waterproofing FAQs
How often should sealants be replaced on a Modesto building?
In Modesto’s heat, expect most joints to need replacing every 10 to 12 years, and south and west walls sooner.
What is the difference between waterproofing and water damage repair?
Waterproofing seals the outside so water cannot get in. Water damage repair fixes drywall, ceilings and finishes once it has. Sealing first means the inside work only happens once.
Can waterproofing be done while the building is occupied?
Yes. Our crews work from the outside and plan around production runs, clinic hours and tenants.
What is the difference between elastomeric coatings and water repellents?
An elastomeric coating is a stretchy paint-like layer that covers small cracks and changes how the wall looks. A water repellent is absorbed into masonry or concrete and keeps water out invisibly.
How do I know if waterproofing can wait another year?
If water came in last winter, or joints are visibly split, plan the work before the next rains. If the caulking is still soft and nothing has leaked, you can usually schedule replacement over the next few years.
When is the best time for waterproofing work in Modesto?
Between spring and early fall, so everything is sealed before the storms. During the hottest weeks we begin at sunrise so materials cure properly.
