Expert High-Rise Facade Repair, Sealant Replacement & Building Envelope Protection
Commercial Facade Restoration Specialists in Los Angeles, CA
Los Angeles wears a facade down quietly. From the curtain-wall towers of Bunker Hill and Century City to the older masonry along Broadway and Spring Street, exteriors here sit under some of the highest UV loads in the country, absorb marine-layer damp overnight, and give it back to the afternoon heat. Sealants lose elasticity and split. Architectural metals dull and chalk. Glass clouds with mineral deposits from irrigation and a season’s worth of fine airborne grit, and wildfire smoke leaves a film that ordinary washing does not lift. Meanwhile the ground keeps moving, so the joints doing the waterproofing are worked mechanically as well as chemically. None of it looks urgent until a winter storm arrives and the water finds every opening at once.
Presto Restoration delivers a complete facade restoration, caulking, and waterproof coating program built for that combination. Our crews pair industrial rope access and swing-stage capability with restoration products we manufacture ourselves, so we can correct every weak point in the exterior envelope: replacing spent sealants with high-movement systems, refinishing corroded architectural metals, applying UV-stable elastomeric membranes, and repointing masonry. The building looks sharp, performs watertight, and is ready for whatever the next wet season brings.
OUR FACADE RESTORATION SERVICES IN LOS ANGELES
When commercial buildings leak, deteriorated caulking is almost always the culprit. In Los Angeles the sealant is attacked from two directions at once: an extremely high UV index breaks it down chemically, while daily thermal swing and long-term structural movement work it mechanically. Joints split, debond, and open direct channels for the next storm to use. Presto’s high-rise technicians strip out the spent material, prepare each joint, and set proper backer rod. They then install industrial-grade silicone and polyurethane sealants specified for high movement and sustained UV. Window perimeters, expansion joints, panel joints, penetrations, and control joints are all addressed in a single coordinated pass across the entire facade.
Los Angeles curtain-wall towers put enormous expanses of aluminum, ACM panel (Alucobond), mullion, and architectural trim under sun for most of the year. That exposure fades factory color, dulls anodized and painted finishes, and lets traffic soot and wildfire ash bond into the surface where ordinary washing never reaches them. Before you budget for wholesale panel replacement, let our metal restoration team recover the original finish. Controlled micro-abrasion strips away oxidation and embedded contamination, and refinishing revives factory color and luster. Owners get like-new metal surfaces at a fraction of replacement cost, with far less disruption. (Restored metal is typically sealed with a protective clear coating afterward: see our Commercial Waterproofing services, which pair naturally with this work.)
On Los Angeles high-rises, glass takes abuse that no window-cleaning contract can undo. Irrigation overspray bakes mineral deposits into the surface under a sun that runs most of the year; alkaline runoff from concrete and masonry etches permanent damage; and the fine grit that blows through the basin, along with ash after a bad fire season, leaves haze and micro-scratching behind. Our chemical glass restoration process dissolves staining, lifts mineral contamination, and removes surface damage while preserving the glass itself, returning true optical clarity to your curtain wall. (To hold that clarity, ask about our proprietary Glass Defender treatment, covered on the commercial waterproofing page.)
Stucco, EIFS, precast concrete, and masonry share one weakness, and Los Angeles has an enormous stock of all four: porosity. The city’s rain arrives in a few concentrated winter storms rather than spread across the year, so a wall that has been drying out for months takes on water fast, and it goes deep. There it feeds rebar corrosion, concrete spalling, and progressive cracking that the next dry spell simply hides again. Presto installs elastomeric waterproof coating systems that cure into a flexible, breathable membrane. The membrane moves with thermal cycling and with the structure itself, bridges hairline cracks up to 1/16 inch, and stops bulk water at the surface while letting trapped vapor escape. Systems come in a complete palette of factory colors and finishes, so your waterproofing doubles as a facade facelift.
From the granite and terra cotta of the Historic Core to the cast stone and limestone of Mid-Wilshire and the Miracle Mile, masonry carries much of the architectural character in Los Angeles. Its porous nature makes it a collector of airborne grit, biological staining, and efflorescence, and decades of traffic soot leave a darkened surface that owners often assume is permanent. We open every stone project with careful substrate evaluation and gentle, controlled cleaning that lifts contamination without scarring the surface, then apply penetrating sealers and breathable waterproof coatings that block moisture while preserving the material’s natural character. Spalled or damaged sections receive color-matched patching engineered to perform like the original substrate.
In any brick wall system, the mortar fails long before the masonry does. Once joints have eroded, a single Los Angeles winter storm sends rainwater straight through the wall assembly, producing interior leaks, efflorescence blooms, and eventually loosened, failing brickwork.
Presto’s masonry crews grind eroded joints to the proper depth, install replacement mortar matched to the original in color, compressive strength, and composition, and tool the finished joints to reproduce the wall’s original profile: structural repointing and decorative tuckpointing handled by a single accountable team.
On older Los Angeles buildings, and on anything inside an HPOZ, we specify lime-based mortar blends consistent with period construction.
Our Facade Restoration Process in Los Angeles
Presto runs every Los Angeles facade project through a disciplined five-phase process, built to surface every defect before work begins, keep crews and building occupants safe during execution, and hand over fully documented results at completion.
Building Envelope
Assessment
We inspect the full envelope from the ground, by drone, and at arm’s length via suspended access. Sealants, metals, glass, stone, coatings, and masonry are photographed and logged: every defect mapped before pricing.
Diagnostic Testing
Where leaks or concealed deterioration are suspected, we run controlled water spray tests, infrared thermography scans, and moisture readings to trace intrusion back to its true source instead of patching symptoms.
Scope & Planning
Findings become a line-item scope with quantities, specified products, and a phased schedule. Your project manager handles access logistics, occupant communication, and permitting with LADBS or the relevant city building department.
Restoration Execution
Certified rope-access and swing-stage crews perform the restoration to manufacturer specification, with field supervisors enforcing quality control and documenting progress daily.
Closeout & Warranty
At turnover you receive the complete record: warranty documents, product data sheets, before-and-after imagery, and a maintenance roadmap to protect the investment going forward.

Los Angeles Facade Restoration FAQs
How often should a commercial facade be restored in Los Angeles?
Sun, not rain, sets the cycle here. We typically recommend a full building envelope inspection every 3-5 years, sealant replacement every 8-12 years, elastomeric coating renewal every 10-15 years, and masonry repointing every 20-35 years. South and west elevations, and any building with significant unshaded glazing, usually need to work off the shorter end of those windows, because that is where UV and thermal cycling do the most work.
What are the warning signs a Los Angeles building needs facade restoration?
Watch for caulking that has cracked, shrunk, or pulled loose from joints; rust streaks bleeding from metal fasteners or panels onto stucco or concrete; coatings that have gone chalky and leave residue on a hand; white efflorescence on masonry and cast stone; stucco that is cracking or discolored; interior water stains that show up only after a winter storm; glass that stays hazy even after cleaning; and spalling concrete around balconies, railings, or window openings. Taken together these say the envelope is failing rather than merely dirty, and the sensible time to look is autumn, before the wet season rather than during it.
Can you restore a facade without disrupting tenants or residents?
Yes. We regularly work on occupied offices, hotels, and mixed-use towers throughout Los Angeles. Rope access lets us avoid the footprint and noise of scaffolding, which matters on tight Downtown sites where there is nowhere to put it; we schedule disruptive tasks outside peak hours where possible, keep property managers updated throughout, and phase the work so lobbies, garages, and tenant entrances stay usable.
How long does facade restoration take on a Los Angeles high-rise?
Timelines depend heavily on building height and scope. A focused sealant replacement on a mid-rise can wrap up in 2-4 weeks. A full restoration covering caulking, coatings, masonry, and metals on a 20-30 story tower typically runs 3-6 months. We provide a firm schedule once we’ve scoped the project so boards and ownership can plan around it.
What warranties apply to facade restoration work in Los Angeles?
Warranty terms depend on the specific coating systems, sealants, and repair methods used on your building. We provide complete warranty documentation at closeout and walk owners through exactly what is covered during the scoping phase, before any contract is signed.
Does Presto handle permitting and historic review in Los Angeles?
Yes. Our project managers routinely handle permit applications and documentation with the Los Angeles Department of Building and Safety, and with the separate departments that govern the surrounding incorporated cities in our service area. Where a property is a designated Historic-Cultural Monument or sits within an HPOZ, we work through the Office of Historic Resources review process and specify materials that will survive it. When a general contractor is overseeing other work at the property, we coordinate directly with them on permitting. Presto carries nationwide general liability and workers’ compensation coverage and complies with all applicable California building code requirements.
