Above-Grade Building Envelope Waterproofing for High-Rises, Condominiums & Commercial Properties
Commercial Waterproofing Specialists in Greensboro, NC
Waterproofing fails differently in the Piedmont than it does on a coast, and the difference is worth understanding before you specify anything. Greensboro does not get one storm that overwhelms a joint; it gets the same joint wetted and frozen dozens of times a winter. Water that a sealant would happily shed in September gets in during a January thaw, freezes overnight, and expands by roughly nine per cent inside the joint. Do that forty times and the bond line tears. Freezing rain then loads parapets, copings, ledges and sills with ice that melts straight back down into whatever it opened. Once the system gives way the damage follows the usual sequence: moisture through interior walls, corroding metal, decaying masonry, and mineral runoff staining glass below.
Presto Restoration delivers above-grade commercial waterproofing for commercial properties across Greensboro, from the downtown office towers on North Elm and North Greene to the converted mill complexes and the newer stock along Wendover and Battleground. Our difference is a restoration-first philosophy. Deteriorated surfaces are cleaned and restored first, never simply caulked over, and the waterproofing goes on afterwards. The finished work performs better and lasts longer for it. Expansion joint and crack sealing carries a lot of weight on a building that crosses freezing dozens of times between November and March, and it sits alongside silicone and elastomeric coating systems and breathable masonry water repellents in what we install. Wet glazing and glass sealing sit alongside those, backed by the products we manufacture ourselves, Glass Defender. Narrower problems get purpose-built answers: Leach Stop Protection for precast concrete. Deep specialization produces stronger outcomes than generalist promises, so we work exclusively above grade: not on foundations, and not on below-grade waterproofing.
OUR COMMERCIAL WATERPROOFING SERVICES IN GREENSBORO
From joint sealants to full coating systems, Presto’s above-grade waterproofing services for Greensboro buildings fall into two groups: core systems that keep the building envelope watertight, and specialized restoration-waterproofing services that pair deep cleaning and restoration with lasting protection.
Core Waterproofing Services
A Greensboro building moves through a wider annual temperature range than most owners realise, from single digits on a January morning to the mid nineties in July, and all of that movement concentrates at expansion joints, control joints and facade cracks. A movement joint here has to stay elastic at temperatures where cheap sealant simply goes rigid, and a joint that has gone rigid tears on the first hard freeze. We repair and reseal with high-movement silicone and polyurethane systems built to stretch and compress with the building instead of pulling loose. On Greensboro buildings, proper joint sealing is usually the single highest-value waterproofing repair available.
Glass on a Greensboro building takes a steady chemical beating from above rather than from the air. Mineral-rich runoff off concrete, cast stone and mortar joints washes down the elevation with every storm, hard-water irrigation overspray dries on the surface through the summer, winter de-icing chemicals splash the lower floors, and spring pollen bonds into whatever is already there. Left alone these deposits etch and haze the glass permanently. Our proprietary Glass Defender bonds a hydrophobic barrier onto the glass. Minerals find nothing to anchor to, water sheets off rather than drying in place, and cleaning becomes both easier and less frequent. Treated windows hold their optical clarity and resist staining through year after year of runoff, pollen and road spray.
Ledges, parapets, coping stones and balcony edges are where a Greensboro building gets hurt. Water sits on them, and in this climate water that sits eventually freezes, which is a very different problem from water that runs off. For those surfaces we install high-performance silicone coating systems: seamless monolithic membranes that bond directly to the substrate and eliminate the laps and terminations ordinary products fail at. Silicone holds up exactly where other coatings give out, tolerating standing water, repeated freeze-thaw cycling, and a temperature swing that runs most of a hundred degrees across the year. That makes it our first answer for every flat and near-flat detail on a Piedmont facade.
Look at almost any commercial tower and the sealant joint between the window glass and its frame is among the first waterproofing components to fail. Dozens of freeze-thaw crossings between November and March work that joint hard. Once that perimeter seal hardens, splits or releases, the path is open, and the heavy convective rain of a Piedmont summer drives straight into the wall cavity. From there it can travel several floors before it shows up indoors, which in Greensboro often means a February leak that is not noticed until the spring rains. Wet glazing cures the problem at the source. The spent sealant comes out, and new high-performance silicone goes in to re-establish a watertight bond between the glass unit and the frame. Presto reglazes storefront, curtain wall, ribbon window, and punched window systems alike, delivering documented, warrantied wet glazing across entire Greensboro buildings.
Stucco, EIFS and concrete walls all develop hairline cracks eventually, and in the Piedmont every one of them is a place for water to enter and then freeze. Elastomeric coatings answer that by staying flexible for life: applied at roughly ten times the film thickness of ordinary paint, they stretch across small cracks instead of splitting themselves. Flexibility at low temperature is the property that matters most here, because a coating that stiffens in the cold cracks precisely when the wall needs it most. Our systems stay breathable so interior vapour can escape through a humid summer, hold up under UV, and come in a full palette of factory colors and texture profiles.
Porous masonry such as brick, block, precast and cast stone drinks in water, and Greensboro has a great deal of it. A saturated wall going into a hard freeze is how spalled brick faces, efflorescence streaks and damp interior walls begin. Silane and siloxane chemistry sits behind the clear, breathable penetrating repellents Presto applies. They soak into the substrate and render it hydrophobic, and the appearance of the wall does not change, which matters on downtown brick, terra cotta and cast stone that still needs to breathe. The wall looks untouched afterwards. Rain beads and rolls off rather than absorbing in, so far less water is sitting in the masonry when temperatures drop below freezing. These sealers are invisible once cured, stable under UV, and formulated to keep working through years of freezing and thawing.
Specialized Restoration-Waterproofing
Sealing a surface is the last step here, not the first. Cleaning and restoration come before it, and that is what makes Presto unique. Waterproofing carried out in those two steps looks better, performs better and lasts longer than standard contractor work. Some problems sit outside what an ordinary waterproofing contractor can handle, and those are exactly the ones our specialized restoration-waterproofing services address.
Water-soluble minerals sit inside precast concrete panels. Whenever moisture works its way through, those minerals leach out, and the runoff deposits on the surfaces below as stubborn, permanent-looking staining on windows, metal trim and other facade elements. Removal is difficult, and because the source of the leaching was never treated, the staining is usually back within weeks of a cleaning. Our Leach Stop Protection is the treatment for it, and it works on the cause rather than the stain, shutting the leaching down at source. Existing staining is cleaned off, then the precast is treated to block future mineral migration. Buildings that have battled recurring window staining for years finally get lasting relief.
Architectural metal panels, curtain wall framing, mullions and Alucobond composite panels corrode from the edges and the horizontal joints, where meltwater collects and sits, and from road de-icing chemicals thrown up onto the lower storeys through a Piedmont winter. Costly panel replacement is not the first thing we push. Protective clear coating systems go on instead, sealing the metal against corrosion. These systems also preserve the original factory finish. Bonding directly to the existing metal surface, the clear coats keep moisture and salt off the substrate underneath, road salt and de-icing chemicals thrown onto lower elevations through the winter included. The original material therefore stays in service meaningfully longer. Expensive replacement projects are frequently avoided this way, and long-term maintenance costs come down significantly.
Our Commercial Waterproofing Process in Greensboro
A proven five-phase process runs on every commercial waterproofing project. It is built to diagnose the issue correctly, specify the right systems for your building, and deliver watertight performance that holds up for years.
Building Envelope Inspection
Sealed joints, coatings, exposed decks, masonry walls: every above-grade waterproofing system on your building is inspected, and each failure point is documented with photos and detailed notes.
Diagnostic Testing
Water intrusion rarely starts where it appears. Controlled water testing, moisture readings and visual tracing separate the true root cause from the surface symptom, which matters here because a leak can enter in a January thaw and surface months later.
Scope & Specification
We specify the right products for your substrates, silicones, elastomeric systems, traffic membranes, with clearly quantified line items, while our PM team handles City of Greensboro permitting and tenant coordination.
Waterproofing Installation
Access is matched to the structure, so our trained crews execute by rope access, swing-stage or lifts as the building requires. Manufacturer specifications govern every installation, backed by strict quality control and full documentation.
Project Closeout & Warranty
Complete documentation is handed over at the end: warranty information, product data sheets, before-and-after photography, and maintenance recommendations that help you get the longest life out of your new waterproofing systems.

Greensboro Commercial Waterproofing FAQs
How often should commercial building sealants be replaced in Greensboro?
Sealant here is not killed by sun so much as by movement at low temperature. Every freeze-thaw cycle asks the joint to stretch when the material is at its least elastic, and the Piedmont runs dozens of those cycles between November and March. Many products are rated for 15 to 25 years, but on exposed Greensboro facades, particularly at parapets, copings and south-facing ledges, we routinely see meaningful failure at 10 to 15. A full building envelope inspection every five years is the reliable way to catch it before it becomes interior damage.
What is the difference between waterproofing and water damage restoration?
Waterproofing is preventative. It keeps water out of the building in the first place, through correctly installed sealants, coatings and membranes. Water damage restoration is what happens afterwards, cleaning up and repairing once water is already inside. Presto works on the preventative side, restoring and maintaining the exterior systems that keep the envelope closed, which is almost always cheaper than repeatedly remediating the inside of the same wall.
Can waterproofing be done on an occupied commercial building?
Yes, and most of our projects are on fully occupied buildings: offices, hotels, hospitals, university buildings and mill conversions. We use industrial rope access wherever possible instead of scaffolding, schedule the noisier work outside peak hours, keep tenants informed throughout, and phase the work so common areas and daily operations stay accessible.
How is an elastomeric coating different from regular exterior paint?
Exterior paint is built for appearance. It offers colour and a little weather resistance, but it will not stretch with the building or bridge a crack. An elastomeric coating is a waterproofing system that also happens to look good: it goes on far thicker than paint, flexes with thermal movement in the substrate, and bridges hairline cracks so water cannot work through. In a market that freezes and thaws as often as Greensboro does, that flexibility at low temperature is the whole point, and it is why an elastomeric system outlasts paint by a wide margin here.
How do I know if my building needs waterproofing now or can wait?
Signs that call for attention now: joint sealant that is cracking or separating, dark streaking running down the wall below a failed joint, efflorescence blooming on masonry or concrete, damp spots or bubbling paint on interior walls, coatings that are chalking or peeling beyond normal wear, and any visible spalling or exposed rebar at parapets, ledges or deck edges. In Greensboro the answer to ‘can it wait’ is usually no, because the next winter runs another few dozen freeze cycles through whatever opening already exists. Tell us what you are seeing and our team will help you prioritise.
Does Presto handle permits and local regulations in Greensboro?
Yes. Our project management team handles permit applications directly with City of Greensboro Planning and Development and with Guilford County, including association and ownership approvals and any required design review submissions. Work on a building inside a local historic district such as College Hill, Fisher Park, Dunleath or Summit Avenue goes through the Greensboro Historic Preservation Commission, and we prepare and carry that submission as part of the scope. Presto carries nationwide general liability and workers’ compensation insurance and complies with all applicable local and state requirements on every project.
