Commercial Window and Glass Cleaning
Interior glass, partitions and storefront cleaning are ordinary scheduled work, typically quarterly or semi-annual. Exterior high-rise window cleaning is a regulated trade governed by New York State Industrial Code Rule 21 (12 NYCRR Part 21) and OSHA fall-protection standards, and it requires a specialist contractor with the right licences, anchor certifications and insurance — not your janitorial vendor.
We do the glass you can reach. We coordinate, vet and supervise the glass you cannot — and we are explicit about the boundary, because this is an area where a cleaning company saying yes to something it should not is how people get hurt.
Interior Glass Is Underrated
In a modern office fit-out, glass is most of what people actually look at: demountable partition systems, phone booths, conference room fronts, entry doors and sidelights. It shows fingerprints within hours and it is the single most visible indicator of whether a space is being maintained. Nightly service covers spot cleaning at high-touch points. A full scheduled glass cycle — both faces, frames, tracks and hardware — belongs on a quarterly rotation.
What Governs Exterior Work in New York
If someone proposes exterior high-rise work, these are the rules that apply, and you are entitled to ask which ones they hold documentation for:
| Rule | What it governs | Whose obligation |
|---|---|---|
| 12 NYCRR Part 21 | NY State Industrial Code Rule 21 — protection of persons employed at window cleaning | Contractor and building owner |
| OSHA 29 CFR 1910.27(b) | Rope descent systems; requires written owner certification that each anchorage has been inspected and certified within the last 10 years | Building owner |
| OSHA 1910.28 / 1910.29 | Fall protection and walking-working surfaces | Contractor |
| ANSI/IWCA I-14.1 | Window cleaning safety standard | Contractor |
| NYC DOB suspended scaffold permit | Suspended scaffold operations require a DOB-licensed rigger | Contractor |
| NY Labor Law §240 / §241 | The “Scaffold Law” — near-absolute liability on owners and contractors for elevation-related injury | Owner and contractor |
| Local Law 11 / FISP | Facade inspection for buildings over six storeys, on a five-year cycle | Building owner |
First, ask your building for the anchor certification date — OSHA requires the owner to certify anchorages at least every ten years, and expired certification is common. Second, check that the contractor's insurance does not carry an Action Over exclusion. Under New York's Scaffold Law, that exclusion is exactly the coverage you would need.

Window Cleaning: Frequently Asked Questions
How often should office windows be cleaned?
Interior glass and partitions quarterly for most offices; monthly if you are client-facing or have a lot of glass in the reception path. Exterior commercial glass is typically quarterly or semi-annual, and in many buildings the schedule is set by the landlord, not by tenants.
What does high-rise window cleaning cost?
It is priced per window and scales with height: roughly $0.75–$1.50 per window at 10–20 storeys, $1.50–$3.00 at 20–50, and $2.50–$5.00 and up above that. Rush scheduling adds 50–100%. Interior glass is quoted per elevation or per square foot of glazed area.
Can your nightly crew do our windows?
Interior glass, yes — it is on the weekly and quarterly rotation. Anything requiring elevated access beyond a standard ladder, no. That is a licensed trade with its own insurance requirements, and a cleaning company that tells you otherwise is one you should not hire.
