Rope access for towers, hotels and strata where a lift cannot stand. IRATA Level 3 on every job, two technicians minimum, from $1,540.

High rise window cleaning is priced by the building, not by the pane. A job starts at $1,540 with two technicians on site, and the figure moves with the number of drops, the anchors available and when the building will let you work.
Every job is run under IRATA Level 3 certification. That matters less as a badge than as a fact about who is on the rope: Level 3 is the grade that can supervise a site and effect a rescue, and it is the reason two technicians is a minimum rather than a preference.
Offices, hotels, serviced apartments and strata-managed towers. Glass first, but the same access does facade cleaning, gutters at height and anything else a pole cannot reach.

The instinct on a tall building is to hire a lift, and on plenty of buildings that is correct. It stops being correct in four situations, and most towers have at least one of them.

Abseil window cleaning is a controlled descent on two independent systems: a working line that carries the technician and a backup line that catches them if the first one fails. Neither is trusted alone, and that redundancy is the whole discipline.
Four things worth asking for on any quote for work at height, including ours. A company holding a certification is not the same as the certified person turning up.
Most quotes say “fully insured” and stop there. This is the number behind it, and the certificate of currency goes to the building with the quote rather than after the job.
IRATA runs three grades. Level 3 is the highest, and the one that can supervise a site and carry out a rescue. It is held by the founder, who attends, and it is why two technicians is the minimum.
The Australian unit of competency for work above two metres, held alongside a WorkSafe Victoria construction induction card. Both are sent by name before anything is rigged.
Rope rescue is only half of it. The IRATA technician on site holds a current first aid certificate, because the minutes that matter happen well before an ambulance reaches a rooftop.
A facilities manager or a strata committee is not buying clean glass. They are buying the confidence that nothing goes wrong on their building, on their insurance, during their trading hours.
So the paperwork goes out before the quote is accepted rather than after. A Safe Work Method Statement written for that specific building and its specific access, not a template with the address swapped.
IRATA certification for the technicians attending, by name. This is worth checking on any quote you receive: a company holding a certification is not the same as the certified person being the one who turns up.
Certificates of currency, construction induction cards, and a notice to residents or tenants that the building can send out under its own name. We write that notice; it lands better from the building than from a contractor.
None of this is unusual for the industry. What is unusual is how often it arrives late, after somebody has already agreed a price.

One fixed number, and everything above it quoted after somebody has looked at the building. Two towers of identical height can differ by thousands once the drops are counted and the anchors are found.
from — two IRATA technicians, one day, rigging and ground zone included
The minimum includes GST, both technicians, rigging, the ground zone and the documentation pack. Out-of-hours work, permits and traffic management where the ground has to be closed are quoted as separate lines so you can see what is access and what is cleaning.
Six things move a high rise cleaning quote, and the height of the building is not the first of them. Two towers of the same storey count can sit thousands apart before anyone has counted a pane.
The quote separates these rather than folding them into one rate per square metre, so a committee comparing two prices can see where the difference sits.

It starts with looking at the building, from the footpath and from the roof. Nothing useful can be quoted from an address and a photograph, because what decides the job is where the anchors are and what is underneath.
Then the documents go to whoever manages the building, and the building sends its notice to occupants: which elevations, which days, windows closed, balconies clear, nothing left on a sill.
On the day, the ground zone goes in first. Cones, signage and a technician at the base for as long as anyone is on rope. Then the descents, elevation by elevation and drop by drop.
On a hotel in Albert Park that was four days with three technicians to cover the full envelope. Three towers on Gladstone Street in South Melbourne, twenty-two to twenty-five storeys, took a crew of four about three weeks.
Photographs at the end, elevation by elevation, because on a tall building the person paying has no way to inspect the work themselves.

Common glass, shared cost and a committee that has to compare quotes. Usually scheduled annually, because on a tower nobody can see the state of the glass from their own balcony.
Tenant-facing and judged on it. These jobs run to a calendar rather than to a complaint, and the facilities manager wants the paperwork before the price.
Occupied every night of the year, so the work is planned around guests rather than around the crew. Rope access almost always, because a lift cannot block a hotel entrance.
Laneway elevations, internal courtyards, boundary walls. These are the buildings that call after a lift company has already told them no.
There is almost always a cheaper number available on work like this, and it is worth understanding what produces it before choosing on price. Three things account for most of the gap, and only one of them is efficiency.
One technician instead of two. This is the most common way a quote gets cut, and it is the one that matters: it removes the person whose job is to get the other one down if something goes wrong.
A certification that belongs to the company rather than to the person on the rope. Ask which technician is attending and what grade they hold. It is a fair question and a straight answer takes ten seconds.
A method statement written for a different building. Generic paperwork is not a document, it is a formality, and it is worthless the moment anything is actually reviewed.
We would rather lose a job on price than match it by removing the second technician. That is not a sales position, it is the only version of this work that is defensible afterwards.
Height is rarely the constraint people expect. A rope does not care whether it is hanging twenty metres or eighty, and the technique at the top of a tower is the same as at the top of a four-storey walk-up.
What changes with height is time and weather. Wind closes a job faster than anything else, and above a certain height it does so on days that feel calm at street level. A tower that takes three weeks includes days when nobody went on rope at all.
The other limit is the building itself. Anchors, parapets and the roof structure decide what is reachable, and some buildings were designed around a maintenance unit that has since stopped working.
Where a building has a working BMU, the cradle is usually the right tool and we will say so. Skyscraper window cleaning is not a competition between methods; it is a question of which one that specific building was designed for.
Once there is a technician on a rope, the glass is one of several things that can be dealt with on the same descent, and doing them together costs far less than mobilising twice.
Facade panels and render on the elevations a pole cannot reach. Gutters and box gutters at height, which on a tall building are otherwise a genuine problem to inspect at all.
Solar arrays on roofs that have no safe edge access. Signage, light fittings and anything else mounted where nobody can otherwise stand.
High rise building cleaning quoted as separate visits by separate trades is how a strata budget disappears. If a building needs three things at height in the same year, they belong in one mobilisation.
Because rope access takes two certified technicians and a day, whatever the building. One person on a rope is not a cheaper version of this work, it is an unsafe one, and there is no half-day rate that changes that.
Yes, and it is the right question to ask any contractor. A company can hold certification while sending uncertified people to do the work. Ask for the attending technician and their grade, on every quote you receive.
No. That is a separate accreditation and a separate trade. We use the anchors a building already has, we check them before loading them, and where they are inadequate we say so rather than working around it.
Almost always, and most of our work is on occupied buildings. What it needs is a notice to occupants a few days ahead and agreement on hours, which for retail and hotel frontages usually means early or late.
Work stops. Wind is the limit, and above a few storeys it closes a day that feels calm from the footpath. This is why a tower is quoted in weeks rather than days, and why we do not promise a finish date on a fixed calendar.
Not from the rope. Interior glass is a separate visit organised through the building, because it needs access to occupied floors and it does not need a rope access technician to do it.
A Safe Work Method Statement written for your building, IRATA certification for the attending technicians, certificates of currency, induction cards, and a notice you can send to residents under your own name.
Yes, and it is the cheapest way to do anything at height. Facade panels, gutters, solar and signage can be handled while the rigging is already up, rather than paying to mobilise twice.
