Reversing Freeze-Thaw Damage on Des Moines Towers, Skywalks & Historic Properties
Commercial Building Restoration Experts Serving Des Moines, IA
Downtown Des Moines is a financial district built largely of glass and metal, and glass and metal are exactly what a hundred-degree annual temperature range works hardest on. The curtain wall towers that house the insurance and financial companies here expand through a humid ninety-five degree July and contract through a January that drops below zero, and every sealant joint and gasket in the wall absorbs that movement year after year until it does not. Water that gets into a joint in November is ice by December, and ice does not stay the size the water was. Add the skywalk system, where enclosed glazed bridges span between separate buildings that move independently of each other, and Des Moines has a concentration of movement joints that few cities its size can match.
Presto Restoration is a nationwide commercial contractor with more than 27 years of experience restoring and waterproofing office towers, parking structures and historic properties. Our crews work with industrial-grade caulking systems, elastomeric coatings rated for freeze-thaw cycling, and proprietary surface restoration products for glass, metal and stone. From the curtain wall towers on Grand and Locust to the brick warehouse blocks of the East Village and Court Avenue and the limestone around the Capitol complex, we renew a property’s appearance and rebuild the moisture barrier that protects its long-term value.
OUR BUILDING RESTORATION & WATERPROOFING SERVICES IN DES MOINES, IA
Exterior restoration, waterproofing and envelope consulting for commercial property across Des Moines, West Des Moines and greater Polk County.
Value leaves a commercial asset faster through unchecked water intrusion than through almost anything else, and in Des Moines the intrusion ordinarily begins at a joint that years of expansion and contraction have worked loose. Our crews treat the envelope as one continuous system, protecting plaza decks, exterior wall assemblies, window perimeters, skywalk connections and joints at grade with high-performance membranes and sealants. Everything installed is specified against a climate that runs from below zero to the mid-nineties, because a sealant that embrittles in the cold has already failed whether or not it has visibly let go.
In a downtown built on financial services the facade is carrying two jobs, one physical and one reputational: it keeps weather out, and it tells tenants, brokers and investors how the asset is being run. We restore both through complete caulking and sealant replacement, architectural metal refinishing, glass renewal and elastomeric waterproof coatings, with stone cleaning and sealing and brick repointing completing the scope. Which of those leads depends on the building, since the older masonry of the East Village and Court Avenue needs a different emphasis than a Grand Avenue tower does.

Structured parking here absorbs a form of attack that a warm-climate deck never experiences. Each vehicle arriving off a salted street in January delivers brine and slush onto the deck, that meltwater descends through cracks and joints, and the chloride in it reaches the reinforcing steel. Corroding steel expands, and expanding steel fractures concrete from within, which is why the damage is structural before it is visible. The exposed top level meanwhile runs the full freeze-thaw cycle with nothing above it. Our crews interrupt that sequence with traffic coating systems, concrete repair, expansion joint replacement and structural waterproofing.
Before a tear-off is authorized it is worth establishing whether one is necessary, because restoration can return 10 to 20 years of service life on a sound roof at a fraction of replacement cost and without closing floors. We install high-performance silicone and elastomeric coating systems, rebuild flashing and penetration seals, and correct ponding before the spring thaw converts it into a leak. Silicone carries a minimum application temperature, so scoping happens over the winter and the field work is placed inside the open season rather than left waiting on a forecast.
A designated property narrows the options before the scope is written, and Des Moines has a deep and varied inventory of them: the limestone of the Capitol complex, the Victorian and Queen Anne houses of Sherman Hill, the brick warehouse blocks of the East Village and Court Avenue, and the early twentieth century commercial buildings along Locust and Walnut. Preserving those calls for period-correct materials, specialized craftsmanship and close coordination with local preservation review. We work alongside owners, architects and review authorities to stabilize aging structures and renew original detailing, which in this climate means soft lime mortars and breathable treatments that let a wall shed moisture before it freezes rather than holding it there.
A chronic leak is rarely presenting at its entry point, and in this market it is often not presenting in the season it entered either: water that arrived as snow can sit on a roof or a skywalk deck for weeks and surface indoors only during a thaw. Our diagnostic specialists isolate the actual failure through controlled water testing, infrared thermography, moisture meter surveys, drone imaging and hands-on facade inspection. The documented findings are what convert a restoration scope from educated guesswork into verified fact.

Frequently Asked Questions About Building Restoration in Des Moines, IA
Which commercial property types does Presto restore in the Des Moines metro?
Nearly every category: downtown office towers, insurance and financial headquarters buildings, hotels, parking structures, hospitals, government and institutional facilities, the skywalk bridges connecting much of the core, and designated historic landmarks. Our crews work across every exterior surface type in that inventory, including glass curtain wall, metal panel, stone, masonry, stucco, EIFS, concrete and roofing systems.
What does the Iowa climate actually do to a building envelope here?
Movement first, ice second. A Des Moines building passes through a temperature range well past a hundred degrees each year, so the wall expands and contracts and every sealant joint, gasket and termination absorbs that cycle. Once a joint loses its bond, water enters, and the second force arrives: it freezes, expands roughly nine percent, and levers the opening wider. Dozens of freeze-thaw cycles in a winter do more to a masonry joint than a decade of mild weather. De-icing salt then attacks parking decks and the lower courses of walls from the splash zone up, while heavy spring storms and hail add their own loading. The practical consequence is that envelopes here fail at the details rather than in the middle of the field.
What duration should a Des Moines restoration project be planned for?
It tracks with building size and scope, and here with the calendar as well. A focused caulking and sealant replacement on a mid-rise may occupy two to four weeks of field work, while a complete facade restoration on a downtown tower can span three to six months. Sealants, coatings and mortar all carry minimum application temperatures, so exterior work is planned into the open season and a project starting late can carry over to the following year. Our project managers coordinate directly with building management and phase the work zones so tenants and amenities stay functional throughout.
Who manages permits and inspections in Polk County?
Our team does, handling permit applications and inspections with the City of Des Moines and the surrounding municipal building departments. Where a general contractor is running broader construction on site, permitting is coordinated through the GC, and clients who prefer to pull permits themselves are welcome to. Presto carries nationwide general liability and workers’ compensation coverage on every project.
Where is the line between restoration and maintenance?
Maintenance is the recurring cosmetic work, window washing, pressure cleaning, touch-ups, that keeps a property presentable. Restoration is corrective: rebuilding failed waterproofing, replacing degraded sealants, repairing spalled concrete and corroded metal, and re-establishing the envelope’s ability to keep water out. In a freeze-thaw climate that distinction is not cosmetic at all, because water admitted through a failed joint in November is the ice that widens the joint in December. Restoration protects the structure; maintenance preserves appearances between restoration cycles.
How can an owner tell which of the two their building needs?
By whether what they are seeing is dirt or failure. Caulk joints cracked, shrinking or pulling free. Rust bleed trailing below metal components. Spalled concrete or exposed rebar. Efflorescence blooming across masonry, which means water is moving through the wall and depositing salts as it dries. Interior stains appearing during a thaw rather than during rain. Glass that stays hazy no matter how often it is cleaned. Each of those indicates active envelope failure rather than a cleaning problem. Describe the condition and we will say which of the two it is.
