Above-Grade Building Envelope Waterproofing for Houston High-Rises, Campuses & Commercial Property
Commercial Waterproofing Specialists in Houston, TX
Waterproofing a Houston building is a movement problem before it is a water problem. Groundwater withdrawal has pulled aquifer levels down 300 to 400 feet and sunk roughly 3,200 square miles of this region more than a foot since 1836, with some locations down twelve or thirteen feet. Four subsidence districts were created to manage it, and levels are still falling in northern and western Harris County and southern Montgomery County. On top of that, Gulf Coast clays swell through the wet season and shrink through drought. All of that motion has to go somewhere, and it goes into the expansion joints, control joints and glazing perimeters of the envelope. Then the weather arrives: nearly 52 inches of rain a year, much of it horizontal, sustained UV through a long cooling season, and dew points high enough that vapour drives inward rather than outward.
Presto Restoration delivers above-grade commercial waterproofing across Houston, from CBD and Uptown-Galleria towers to Texas Medical Center campus buildings, Energy Corridor and Westchase office stock, and the precast and tilt-up along the Ship Channel. Our difference is a restoration-first approach. Rather than caulking over a deteriorated surface, we clean and restore it first, so the finished work performs better and lasts longer. Capabilities include high-movement expansion joint and crack sealing, breathable masonry water repellents, silicone and elastomeric coating systems, and wet glazing and glass sealing backed by our proprietary products such as Glass Defender. We also provide niche solutions like Leach Stop Protection for precast concrete. We work exclusively above grade, not on foundations or below-grade waterproofing, because deep specialization produces stronger outcomes than generalist promises.
OUR COMMERCIAL WATERPROOFING SERVICES IN HOUSTON
Two things keep a Houston envelope dry, and we do both. The core systems close the paths water uses: movement joints, glazing perimeters, coatings and porous masonry. The specialized restoration-waterproofing services deal with the problems this market’s precast-heavy stock produces, cleaning and restoring a surface before protecting it rather than sealing over the damage.
Core Waterproofing Services
This is the single highest-value waterproofing repair available on most Houston buildings, and the reason is under the building rather than on it. A concrete high-rise already flexes with wind load and daily heat cycling. Add regional subsidence and clays that swell and shrink with the season, and the total movement arriving at every expansion joint, control joint and facade crack is larger than the original sealant was ever asked to absorb. When it lets go, that joint becomes the fastest path for horizontal rain into the interior. We repair and reseal with high-movement silicone and polyurethane systems specified against the movement the joint actually sees, so they stretch and compress with the structure instead of tearing loose from it.
Glass on a Houston tower collects a steady chemical load. Mineral-rich runoff washes down from concrete and precast above, irrigation overspray bakes on under a long hot season, and urban and industrial particulate settles into the surface. Left alone, all of it etches and hazes the glass permanently. Our proprietary Glass Defender treatment bonds a hydrophobic barrier to the surface so minerals cannot anchor, water sheets away instead of drying in place, and routine cleaning gets easier and less frequent. Treated glazing holds its optical clarity through years of Gulf Coast heat, humidity and storm exposure.
Ledges, parapets, balcony edges and other horizontal details are where nearly 52 inches of annual rainfall sits and waits, and where conventional coatings surrender first. For those conditions we install high-performance silicone coating systems: seamless monolithic membranes bonded directly to the substrate, with none of the laps and terminations where ordinary products fail. Silicone is at its best exactly where other chemistries die, shrugging off standing water, sustained UV and the daily thermal cycling of a long Houston summer. That makes it our default answer for the flat and near-flat details that collect water on commercial buildings here.
Houston has a recent and very public reminder of why wet glazing matters. When the May 2024 derecho crossed the city, downtown towers lost glass outright and re-glazing work ran on for months afterward. Even without a storm that severe, the sealant joint between the glass and its frame is among the first waterproofing components to go. Once that perimeter seal hardens, splits or releases, wind-driven rain enters the wall cavity and can travel several floors before anything appears indoors. Wet glazing fixes it at the source: we remove the spent sealant and install new high-performance silicone that re-establishes a watertight bond between the glass unit and the frame. Presto reglazes storefront, curtain wall, ribbon window and punched window systems, with documented, warrantied work across entire Houston high-rises.
Stucco, EIFS and concrete walls develop hairline cracks eventually, and in Houston every one of them is an entry point waiting for the next storm. Cracking here is not only thermal, either. Buildings on settling ground and shrink-swell clay keep opening the same cracks faster than a rigid coating can bridge them. 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 open. Our systems are breathable, which matters where vapour drive runs inward for most of the year, stable under a long high-UV season, and available in a full palette of factory colours and texture profiles.
Porous masonry such as brick, block, precast and cast stone drinks in water, and Houston supplies close to 52 inches of it a year. The result is efflorescence, mineral leaching that streaks the surfaces below, accelerated deterioration and damp interior walls. Presto applies clear, breathable penetrating repellents built on silane and siloxane chemistry that soak into the substrate and render it hydrophobic without altering its appearance. After treatment the wall looks untouched, but rain beads and rolls off rather than absorbing. These sealers stay invisible once cured, hold up under sustained UV, and keep working through years of Gulf Coast heat and humidity.
Specialized Restoration-Waterproofing
What makes Presto different is that we do not simply seal surfaces, we clean and restore them first. That two-step approach produces waterproofing that looks better, performs better and lasts longer than standard contractor work. Our specialized restoration-waterproofing services handle the specific problems ordinary waterproofing contractors are not equipped for, and on Houston’s precast-heavy commercial stock those problems come up constantly.
Precast concrete is everywhere in Houston, on 1970s and 80s office towers, medical campus buildings and parking structures alike, and it carries water-soluble minerals that leach out whenever moisture moves through the panel. The runoff deposits on whatever sits below it, leaving stubborn, permanent-looking staining on glass, metal trim and adjacent facade elements. Cleaning alone does not hold, because the leaching itself was never addressed, and the stains return within weeks. Our Leach Stop Protection service treats the cause. We clean the existing staining and treat the precast to block further mineral migration, so a building that has fought recurring window staining for years finally gets lasting relief.
Architectural metal panels, curtain wall framing, mullions and Alucobond composite panels take a continual load from Houston’s long high-UV season, persistent humidity and the airborne particulate a heavily industrial metro produces. Rather than pushing owners toward costly panel replacement, we apply protective clear coating systems that seal the metal and preserve the original factory finish. The clear coats bond directly to the existing surface and block moisture and contamination from reaching the substrate underneath. That meaningfully extends the service life of the original material. In practice this approach often removes the need for a replacement project altogether, and it cuts long-term maintenance cost substantially.
Our Commercial Waterproofing Process in Houston
Every Houston waterproofing project follows a five-phase process built to diagnose the failure correctly, specify systems rated for the movement and heat this market produces, and deliver watertight performance that holds up for years.
Building Envelope Inspection
We inspect every above-grade waterproofing system on the building, from sealed joints and coatings to exposed decks, parapets and masonry walls, documenting each failure point with photos and notes, and flagging where movement is driving the failure.
Diagnostic Testing
Water intrusion on a Houston building often traces back somewhere unexpected, because horizontal rain travels. Controlled water testing, moisture readings and visual tracing separate the real root cause from the surface symptom.
Scope & Specification
We specify products to the substrate and to the movement the joint actually sees: high-movement silicones, elastomeric systems, traffic membranes, with quantified line items, while our PM team handles City of Houston permitting and tenant coordination.
Waterproofing Installation
Trained crews execute using rope access, swing-stage or lifts as the building requires. Work is installed to manufacturer specification with strict quality control, full documentation, and scheduling that respects Gulf Coast cure windows.
Project Closeout & Warranty
We deliver complete documentation, including warranty information, product data sheets, before-and-after photography, and maintenance recommendations to get the most life out of the new waterproofing systems.

Houston Commercial Waterproofing FAQs
How often should commercial building sealants be replaced in Houston?
Sealant on a Houston building is doing two jobs at once, and that shortens its life. It is weathering a long, high-UV cooling season, and it is absorbing structural movement from a metro where the ground is still settling and the clays swell and shrink with the season. Many products are rated for 15 to 25 years. On exposed high-rise elevations here we routinely see meaningful failure at 10 to 15, and sooner in the areas where subsidence is still active. A full 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 specified and installed sealants, coatings, membranes and glazing. Water damage restoration is what happens afterward, cleaning up and repairing once water is already inside. Presto works on the preventative side, restoring and maintaining the above-grade systems that keep water out of the envelope. In a city that delivers close to 52 inches of rain a year, that is almost always cheaper than remediating the interior over and over.
Can waterproofing be done on an occupied commercial building?
Yes, and most of our projects are on fully occupied buildings, from office towers and hotels to medical campus buildings and residential high-rises. We use industrial rope access wherever possible instead of scaffolding, schedule the noisier work outside peak hours, keep tenants informed, and phase the work so common areas and daily operations stay accessible. Houston adds one scheduling factor most markets do not: summer heat and dew point can close a product’s cure window, so we plan around the forecast rather than against it.
What is the difference between elastomeric coatings and regular exterior paint?
Exterior paint is built for appearance. It offers colour and some weather resistance, but it will not stretch with the substrate or bridge a crack. Elastomeric coatings are waterproofing systems that also happen to look good: applied far thicker than paint, they flex with thermal movement and bridge hairline cracking so water cannot work through. That matters more in Houston than in most markets, because cracks here are not only thermal. Buildings on settling ground keep reopening them, and a rigid film fails at exactly those points.
How do I know if my building needs waterproofing now or can wait?
Signs that call for attention now: cracking or separation in joint sealants, dark streaking running down exterior walls below failed joints, efflorescence or mineral leaching on masonry and precast, damp spots or bubbling paint on interior walls, coatings that are chalking or peeling beyond normal wear, and visible concrete spalling or exposed rebar. Add the Houston-specific one: diagonal cracking at an opening, or a joint gone visibly out of square, which indicates the structure is moving rather than the surface degrading. Call 1-800-785-9927 or use Request A Quote and describe what you are seeing, and we will help you prioritise.
Does Presto handle permits and local requirements in Houston?
Yes. Our project management team files permit applications directly through the City of Houston Permitting Center, and through Harris County Engineering or the Fort Bend and Montgomery county authorities for property outside city limits. Houston has no zoning ordinance, so the land-use approvals other cities require simply do not exist here. What usually governs instead is a private deed restriction, along with any owner association or design review the property carries, and we work within those. Specifications are written to the 2021 International Building Code with Houston amendments, in force since 1 January 2024. Presto carries nationwide general liability and workers’ compensation insurance and complies with all applicable local and state requirements on every project.
