Expert High-Rise Facade Repair, Sealant Replacement & Building Envelope Protection
Commercial Facade Restoration Specialists in Boston, MA
Few cities in America subject a building facade to the range of abuse that Boston delivers. Winter brings nor’easters that drive horizontal rain and ice into every joint, gasket and penetration a calm day never threatens. Freeze-thaw cycling follows relentlessly: water trapped in a caulk bead or mortar joint expands each time the temperature drops below 32 degrees, widening the gap for the next round. Between storms, salt air from Boston Harbor works on metal finishes and sealant chemistry the way coastal salt does in any port city. Add road salt and de-icing chemicals tracked across plaza decks, and the envelope is attacked from every direction at once. When sealants split, coatings chalk, brick begins to spall and glass clouds with mineral deposits, water finds its way inside, and interior damage, mold risk, unhappy tenants and declining property value follow.
Presto Restoration takes the whole exterior scope on a Boston building under one contract and one project manager. Our crews bring industrial rope-access and swing-stage capability, and the restoration products that go on the wall are ones we manufacture ourselves. Between the two we can work an elevation in the right order: joints cut out and re-sealed, corroded metal stripped and refinished, elastomeric membrane where the wall needs a continuous skin, and brick and brownstone repointed in a soft high-lime mix rather than a hard cement one that sacrifices the face of the masonry. Sequencing follows the New England calendar, since the acrylic and elastomeric products cannot go onto a cold wall and the sealant and masonry scopes carry the shoulder months instead. What an owner gets back is an elevation that sheds water again, a written record of what was opened up and what was found behind it, and on a high-rise the documented condition basis an engineer needs for the next filing under the Boston facade ordinance.

When a commercial building in Boston leaks, the joint is the suspect long before the wall is. Published service life for exterior sealant runs about seven to ten years for polyurethane and fifteen to twenty for silicone, and the manufacturer warranty is a ceiling that assumes the joint was installed correctly, not a promise of years. Boston then works those joints harder than average: roughly sixty-eight days a year when the air temperature crosses freezing in both directions, most of them December through March, on top of record gust loading and harbor salt acting on the sealant chemistry itself. On filled land in the Back Bay, the South End and Bay Village there is a second driver, because differential settlement over wood pilings opens joints from below, which is why the worst beads on those buildings are often at the base of a wall rather than the top. Presto’s high-rise crews cut the spent material out, prepare and prime the joint walls, set backer rod to the right depth, and install silicone or polyurethane specified for cold-climate movement. Window perimeters, expansion and panel joints, penetrations and control joints all get done in one coordinated pass rather than in patches, and we set the reinspection date on the observed condition of the joints rather than on the warranty date.
Boston’s curtain-wall towers hang acres of aluminum, ACM panel (Alucobond), mullion and architectural trim in the path of two different salts: aerosol off Boston Harbor on waterfront and exposed elevations, and de-icing chloride thrown up off streets and plaza decks all winter. What that produces is pitted, chalked finish, corrosion creeping out from fasteners and panel seams where freeze-thaw has worked moisture in behind them, and a grey film no washing schedule takes off. Replacement is rarely the first answer. Our metal division recovers the finish that is already there, lifting oxidation, corrosion and embedded contamination with controlled micro-abrasion and refinishing back to factory color and gloss, for a fraction of replacement cost and without shutting an elevation down panel by panel. (Restored metal is normally sealed with a protective clear coat afterward, which is covered under our Commercial Waterproofing services and is usually scheduled into the same mobilization.)
On Boston high-rises the damage that dulls glass is chemical, and no window-cleaning contract will reverse it. Alkaline runoff washing down off the concrete, mortar and stone above etches the surface permanently. Salt aerosol off Boston Harbor films waterfront elevations with a haze that comes back as fast as it is cleaned. And at the lower floors, de-icing salt thrown up as splash and spray off the street works on glass and frames from November to March. Presto’s chemical restoration process lifts the staining and the mineral film and takes the etching out of the surface without replacing the unit, so the curtain wall reads clear again. (Holding that clarity afterwards is a separate product: Glass Defender, detailed on our commercial waterproofing page, and most owners here have it applied while the swing stages are still up.)
Stucco, EIFS, precast concrete and masonry all fail the same way in New England, and the reason is porosity. Nor’easter-driven rain and snowmelt push moisture deep into the substrate, and then freeze-thaw takes over: water that has soaked into a hairline crack expands every time the temperature crosses freezing, and the crack becomes a spall. Behind it come rebar corrosion, delamination and efflorescence that get worse every winter rather than every year. Presto’s elastomeric systems cure to a flexible, breathable film that moves with the substrate, bridges hairline cracking up to 1/16 inch, and holds bulk water at the face while still letting trapped vapor out of the wall. Application is the part Boston owners have to plan around. Water-based acrylic and elastomeric products generally want about 50 degrees and rising, with manufacturers cautioning from the mid-50s downward and every product setting its own minimum on its data sheet, so coating work here is realistically an April-to-October scope. Solvent-based silicone and urethane systems stretch the shoulder season, and we will tell you which side of that line your building sits on before you commit the year’s budget. Finishes come in a full factory color range, so the waterproofing doubles as a facade facelift.
From Back Bay’s brownstone and brick row houses to the granite and limestone facades of the Financial District, masonry defines much of Boston’s signature architecture. Brownstone is the demanding one. It is an arkosic sandstone whose grains are held together by carbonate and iron oxide, and it sheds worst where blocks were set perpendicular to their bedding, which is why one course on an elevation can be sound while the course above it delaminates. Quincy granite and Roxbury puddingstone are far tougher, but every porous face in this city takes chloride from two directions, harbor salt aerosol on waterfront exposures and de-icing salt as splash at street level, and then takes freeze-thaw on top of it. So we survey the substrate before anyone touches it, clean at the gentlest method that actually works rather than the fastest, and treat with penetrating sealers and breathable coatings that keep water out without sealing vapor in. Failed sections are cut out and rebuilt with replacement material matched for color, strength and permeability. In the Back Bay Architectural District and the South End Landmark District, masonry cleaning and repair need commission review before work begins, and preparing that submission is part of our scope.
In a brick wall the joints are the sacrificial part, and they go long before the brick does. Once they have eroded, a nor’easter pushes water straight through the assembly, and what shows up is interior staining, efflorescence blooming on the face and eventually brick sitting loose in the wall.
Presto’s masonry crews cut the failed joints back to sound mortar at the correct depth, refill with a mix matched to the original in color, strength and composition, and tool the joint to the profile the wall was built with. Structural repointing and decorative tuckpointing come from one accountable crew instead of two trades.
On Boston’s nineteenth-century stock the mortar has to be softer than the brick, not harder. The Back Bay commission requires a high sand and lime content specifically to protect soft nineteenth-century brick, and Beacon Hill caps the mix at one part cement to two parts lime to seven to nine parts sand precisely so the brick can expand through freeze-thaw without spalling its face. Put a portland-rich mortar on that wall and the joint will outlast the brick around it. Done properly, the National Park Service expects a repointing job to last at least thirty years and often fifty to a hundred, which is why we set the interval on the condition of the joints rather than on a calendar. Repointing also runs inside a temperature window here: wall temperatures between 40 and 95 degrees, completed work protected from freezing, and sand and water warmed rather than antifreeze added, which is a real constraint on a Boston winter schedule.
Our Facade Restoration Process in Boston
Every Boston facade project runs through the same five-phase sequence: find every defect before anyone prices the work, keep crews and occupants safe while it is executed, and hand over a documented result at the end.
Building Envelope
Assessment
We look at the whole envelope from grade, by drone and at arm’s length off suspended access. Sealants, metal, glass, stone, coatings and masonry are photographed and logged elevation by elevation, so the defects are mapped before anything is priced.
Diagnostic Testing
Where a leak or hidden deterioration is suspected we test rather than guess: controlled water spray, infrared thermography and moisture readings, run to trace the water back to where it actually enters instead of patching where it shows.
Scope & Planning
Findings turn into a line-item scope with quantities, named products and a phased schedule. Your project manager carries access logistics, occupant notice, the Inspectional Services permit and any Landmarks Commission submission the district requires.
Restoration Execution
Our own certified rope-access and swing-stage crews do the work to manufacturer specification, with a field supervisor on the building enforcing quality control and logging progress every day.
Closeout & Warranty
At turnover you get the whole record: warranties, product data sheets, before-and-after photography by elevation, and a maintenance interval schedule written for this building rather than a generic one.
Our Local Boston, MA Support Network
Covering Boston’s dense urban core and the wider New England coastline properly takes more than crews flown in for a project; it takes standing local infrastructure. Presto runs a set of specialized regional divisions so a Boston client gets continuous coverage from one relationship, whether the job is a full envelope restoration or routine building care.
When a building wants upkeep rather than a facade contract, these divisions take it on directly:
Building Restoration Boston: Repair confined to one part of a structure, plus preservation of elevations reached by swing stage or rope.
Building Maintenance Boston: Recurring attention to sealant joints, flashings and copings, where an elevation usually begins to fail.
Building Services Boston: Everyday commercial building support, handled locally, for owners in the city.
Why Boston Property Managers Choose Presto for Facade Restoration
Presto Restoration has been protecting commercial property nationwide for more than 25 years, and our presence in the Boston market means we work to what New England actually does to a building: the corrosion cycle that comes with coastal salt, the freeze-thaw and ice-damming conditions that punish every joint and flashing detail, the five-year exterior wall inspection cycle the city puts buildings over 70 feet on, and the review that historic districts require before anyone touches a designated facade.

Boston Facade Restoration FAQs
How often should a commercial facade be restored in Boston?
Not on a fixed calendar, which is the honest answer for this city. Published service life is roughly seven to ten years for polyurethane sealant and fifteen to twenty for silicone, and the National Park Service expects a properly executed repointing job to last at least thirty years and often fifty to a hundred. Every one of those figures assumes the work was installed correctly. Boston then works the envelope harder than average: about sixty-eight days a year when the temperature crosses freezing in both directions, most of them December through March, and a 2025 that set Logan’s record for average wind gust. So we inspect on a cycle, normally every three to five years, and set repair intervals on what the inspection finds rather than on a warranty date. Waterfront stock in the Seaport / South Boston Waterfront and along Boston Harbor sits at the aggressive end of that range, and buildings over 70 feet are already on a five-year exterior wall inspection under the city’s facade ordinance, which is a sensible rhythm to hang the rest of the program on.
What are the warning signs a Boston building needs facade restoration?
The tells worth acting on are the ones that move through a Boston winter. Start at the joints: caulking that has split, shrunk back, or released from one face of the joint is what lets a wall begin taking on water. On brick and brownstone, read the deposits and the surface – white efflorescence tracking down an elevation says water is moving through the wall and drying on the outside of it, and brownstone that is delaminating in sheets often points to a block laid perpendicular to its bedding, a documented weakness of the Portland and East Longmeadow sandstone that built the Back Bay. Metals report in rust: streaking from fasteners, panel edges or a corroding lintel onto the masonry beneath. Coatings go chalky, craze, or drift in color. Concrete spalls first at balcony edges, railing posts and window openings, the places reached by both harbor air and de-icing salt thrown up from the street. Glass that will not clean up is usually etched rather than dirty. Indoors, staining or a musty smell along an exterior wall in the days after a nor’easter, or through the spring thaw, means the wall is already passing water rather than merely holding it. One of these on its own is worth a look. Several together on a building over 70 feet is reason to bring forward the exterior wall inspection the Boston facade ordinance already requires every five years, rather than wait for the date.
Can you restore a facade on an occupied Boston building?
Yes, and in Boston it is usually the only way the work can happen at all. Beacon Hill, the Back Bay and the Financial District have no room to stand scaffolding for months, so we work off rope access and swing stage, which puts the crew on the wall and leaves the sidewalk, the loading dock and the on-street parking alone. Overhead protection and pedestrian routing are planned with the building before we mobilize. We phase elevations so lobbies, garage entries and amenity space stay open, keep the loud operations out of the hours that matter most to residents and tenants, and give the board or property manager a written weekly update with photographs of what actually moved that week.
How long does facade restoration take on a Boston high-rise?
Height and scope drive it, and in Boston so does the calendar. A focused sealant replacement on a mid-rise is typically two to four weeks. A full program covering joints, coatings, masonry and metal on a twenty-plus-story tower in the Financial District or the Back Bay usually runs three to six months. The seasonal constraint is real and worth building into the budget year: water-based elastomeric coatings generally want about 50 degrees and rising, and repointing wants wall temperatures between 40 and 95 degrees with the finished work protected from freezing, so coating and mortar scopes are effectively April through October here. Solvent-based silicone and urethane systems extend the shoulder season, and sealant replacement, metal restoration and glass work carry on through the cold months. We sequence around that, so a program starting in autumn does the winter-capable scopes first and the coating work when the wall is warm enough to take it.
What warranties apply to facade restoration work in Boston?
It depends on the systems that actually go on your building, so we put it in writing rather than in a slogan. Sealant, coating and masonry manufacturers each warrant their own materials, and those warranties are conditional on the substrate preparation and installation method being what the data sheet calls for, which is a large part of why we specify and self-perform rather than subcontract the wall. Presto warrants its own workmanship separately. You see both during scoping, in the specification, before anything is signed, and the complete package with product data sheets is handed over at closeout. One Boston-specific point worth knowing: Massachusetts has no state product-approval or Notice of Acceptance program comparable to Florida’s, so coatings and sealants here are accepted on third-party testing and labeling under the state building code rather than on a state approval number.
Does Presto handle permitting in Boston?
Yes, and in Boston the split between the bodies matters. Our project managers routinely handle permit applications with the City of Boston Inspectional Services Department and coordinate with the Boston Landmarks Commission when work involves designated historic properties. Envelope repair generally goes in as an ISD short-form permit. In a landmark or architectural district the document you need is a Certificate of Appropriateness or Design Approval, and genuine maintenance and repair is often cleared by administrative review rather than a hearing, which is a difference of weeks. The Massachusetts Historical Commission only comes into it when state or federal money, permits or licenses are involved, so on privately funded work the local commission is the body that decides. Where a general contractor is running other work on the property we file alongside them. Presto carries nationwide general liability and workers’ compensation coverage, and we build to the Tenth Edition of the Massachusetts State Building Code.

By the time a stain reaches a tenant’s ceiling, the joint or flashing that let the water in has usually been open for several winters, and Boston’s freeze-thaw cycling only widens what it finds. The cheapest version of the repair is always the one scoped before the next winter. Ask Presto Restoration to review the elevation and price the work.
