Façade restoration and exterior renovation for New York City buildings

Your façade, repaired where repair will hold and renovated where it won't, with the next cycle in mind.

Façade restoration is the repair and rehabilitation of a building's exterior walls: brick, stone, terra cotta, lintels, parapets, joints and sealants. When repair can't keep up, exterior renovation goes further, with new cladding in stone, GFRC, EIFS or metal panel, new windows and doors, stucco systems and façade lighting. In New York the work usually starts with a FISP (Local Law 11) report. Banu carries out every repair in that report and fixes what caused it, then hands your QEWI what they need to file the building as Safe.

When brick cracks at a window head or a floor line, there's usually rusting steel behind it. We fix the steel in the same opening as the brick.

What we deliver

  • Work your QEWI can sign off on.

    Each item is scoped to a condition in your report and finished to the standard your QEWI needs to file Safe.

  • Repairs that hold for the next cycle.

    We go after the cause: corroded steel, failed flashing, open joints. Patch only the symptom and it's back on the report in five years.

  • A straight answer on repair or renovate.

    When a wall keeps failing, we lay out both options side by side, with scope and schedule, so you can decide with the facts in front of you.

  • Your architect's design, built as drawn.

    Mockups, shop drawings and submittals get settled before anything new goes on the wall.

  • Watertight where old meets new.

    New cladding and windows tie into the roof edge and the flashing, so the seam between the two stays dry.

  • One team on the wall.

    One project lead runs the masonry, steel, cladding, sealants, coping and roofing, so nothing gets lost in a handoff between trades.

  • A record of the repairs.

    Photo updates at key milestones, then a close-out package showing what was repaired, where, and how.

  • Rigged under our own license.

    We rig and move the suspended scaffold drops ourselves, under our own Special Rigger license.

Services and capabilities

  • Support for LPC applications on landmarked buildings

02 Restore and renovate

03 Close out

  • A site safety plan, and safety management on site where the job calls for it
  • A walk-through with your QEWI, and a punch list we close
  • Photo documentation for the amended FISP filing
  • Final inspections and sign-offs
  • Warranty and maintenance documentation
  • Sheds and scaffold taken down, sidewalk restored
  • A maintenance plan for the next cycle

Signs your façade needs work

  • Diagonal cracks off the corners of windows, or a horizontal crack along a floor line
  • Brick bulging outward or stepping out of plane
  • Rust stains running down from window heads
  • Pieces of stone, brick or concrete on the sidewalk or a setback roof
  • White powder (efflorescence) blooming on the brick
  • Mortar you can scratch out with a key
  • Water stains inside apartments along the exterior walls
  • Coping stones on the parapet that are loose or rock when you lean on them

Anything that looks loose enough to fall shouldn't wait for the next inspection. Request an Assessment and tell us what you're seeing.

Signs a repair won't be enough

  • The same conditions on report after report
  • White glazed brick that keeps spalling and bulging
  • Stucco or EIFS that sounds hollow when you tap it
  • Panels or windows that leak however often they're caulked
  • A wall that's sound but makes the building harder to rent or sell

The rules that apply

FISP (Local Law 11). Every building greater than six stories needs a façade inspection by a QEWI every five years, and each condition is classified Safe, SWARMP or Unsafe. How FISP repairs work →

Local Law 126 parapets. Any building with a parapet facing the street needs a parapet observation every year, whatever its height. Parapet repairs →

Landmarks. Work on a landmark or in a historic district needs an LPC permit before it starts, and significant changes such as re-cladding go to a public hearing. Landmark restoration →

We join your building at any point

  • Before the inspection.

    Your QEWI needs scaffold drops for the close-up inspections, and you need to know what's coming. We rig the drops ourselves and fix the problems you already know about, so they're repaired before they're reported.

  • Right after the report.

    Send it over. We walk every condition with the report in hand and scope each one separately, so you can follow every repair through to sign-off.

  • Unsafe today.

    Protection goes up first, then a repair plan that fits the 90-day window. Check the Unsafe box on the assessment form and attach the report.

  • Mid-project.

    A job stalled, or a contractor walked off. We verify what was done, document what wasn't, and finish it.

Questions about façade restoration and exterior renovation

What's the difference between façade repair and façade restoration?

Repair fixes the items on the list. Restoration fixes the reason they got there. Say brick is cracking above your windows. Repair replaces the cracked brick. Restoration also takes care of the rusting steel lintel behind it, which is what cracked the brick in the first place, so the same crack isn't back on your next report.

When does re-cladding make more sense than repair?

When you're repairing the same wall every cycle. Think of white glazed brick that spalls again after each repair, delaminating stucco, or panels that leak through every round of caulk. If a façade keeps turning up SWARMP and Unsafe conditions, a new cladding system can serve the building better than patching it every cycle for the next twenty years. We scope both options so you can put them side by side.

Do you need our FISP report before you can scope the work?

It helps a lot, but no. With the report in hand, we scope each condition line by line. Without it, we run our own condition survey and tell you what we'd expect your QEWI to flag.

Can the building stay occupied?

Almost always. Most façade work happens from suspended or pipe scaffold outside the building, rigged under our own Special Rigger license. We plan noise, window access and terrace closures around the people living and working there, and they hear about it from us before it happens.

Do residents have to move out for window replacement?

No. In an occupied building we go unit by unit and plan about one day per apartment for the window itself, with the interior finishing done right behind it. We set the schedule with your managing agent and give residents notice.

How long does a façade restoration take?

It depends on the size of the building, how many elevations need work and how much is hidden until the wall is open. One elevation of repointing and brick replacement can take weeks. A full façade rehabilitation of a tall pre-war building can run a year or more. You get a schedule with our proposal, and we keep it current as the work moves. Our cost guide lays out what drives the size of a job.

Does façade work need a DOB permit?

Most of it does. If your building is landmarked or sits in a historic district, it needs a Landmarks Preservation Commission permit as well. Your architect or engineer files the drawings. We pull the work and shed permits and keep them current.

Can we re-clad a building in a historic district?

Sometimes, but it's a bigger conversation. Changing the look of a landmark, or of a building in a historic district, needs LPC approval, and significant changes go to a public hearing. Your architect leads that process. We help with materials, mockups and constructability.

Will new cladding make the building more energy efficient?

It can. Re-cladding is the one time you can add continuous insulation and close up air leaks across the whole wall, and it's often part of a larger plan for Local Law 97 emissions limits. Treat it as a design decision. Your architect or engineer models the energy performance, and their numbers make the case.

Who designs a new façade?

Your architect. We build from their drawings, put up mockups, submit shop drawings and product data, and flag anything that won't work in the field before it gets built.

What happens when you open the wall and find more damage?

We stop, photograph it and show your QEWI. You see the added scope and agree to it before we go further. Our proposals name the common unknowns and how each will be measured (per brick, per linear foot of lintel, per square foot of stone patch), so you've agreed in advance how they'll be handled.

Across New York City

  • Manhattan: Pre-war masonry and terra cotta, much of it on landmarked blocks.
  • Brooklyn: Newer concrete and EIFS towers beside older masonry.
  • Queens: Post-war brick co-ops, often with a long run of elevations to cover.
  • The Bronx: Art Deco brick and terra cotta along the Concourse and beyond.
  • Staten Island: North Shore apartment buildings and parapets over storefronts.
