What we clean
- Retail and hospitality frontage, cleaned before opening so it is never done in front of customers
- Office glazing, internal and external, including atriums and stairwell glass
- Internal partitions and meeting room glass, which shows fingerprints far faster than exterior glazing
- Entrance doors and surrounds, the highest-touch glass in any building
- Showroom and display glass
- Skylights and roof glazing, where safely accessible
- Frames, sills and tracks, which is where the dirt actually sits


Wellington weather is the reason schedules matter
Wellington is harder on glass than most of New Zealand. Wind carries dust and grit onto glazing constantly, and city sites near the harbour get salt deposition on top of that. Wind-driven grit abrades exposed glazing over time, and salt holds deposits against it that bond if they are left. Abraded glass cannot be cleaned back to clear.
The practical consequence is that a scheduled cycle costs less over the life of the glazing than cleaning reactively, because it prevents the build-up that eventually causes permanent damage.
How often commercial windows should be cleaned
- Retail and hospitality frontage: weekly to fortnightly. It is the first thing a customer sees.
- Office exterior glazing: quarterly for most buildings, more often for exposed or harbour-facing sites.
- Internal partitions and meeting rooms: monthly, or as part of the regular cleaning contract.
- Entrance doors: daily or per visit, as part of the standard clean.
Exposure matters more than the calendar. A sheltered courtyard elevation and a west-facing harbour frontage on the same building will not need the same frequency, and quoting them as if they do is how sites end up either over-serviced or looking neglected.

What a commercial window clean actually involves
Almost every complaint about window cleaning is about streaks, or about dirt running back down the glass a week later. Both come from method rather than from effort.
- The frame, sill and track are cleaned first. Dirt sitting in a track runs back onto clean glass the next time it rains, and that is the single most common reason glass looks dirty again within days.
- Glass is washed, not wiped. A dry cloth on dry glass moves grit around and scratches the surface.
- Water-fed pole systems use purified water, which dries without leaving mineral deposits, so upper glazing can be cleaned properly from the ground.
- Squeegee work at ground and low level, with the edges detailed by hand. The edge is where streaking shows first.
- Internal glass is done with different cloths from external, because the soiling is different: fingerprints and marks rather than grit and salt.
The parts a cheap quote skips are almost always the tracks, the frames and the edges. They are also the parts that decide whether the glass looks clean for a month or for an afternoon.
Etched and damaged glass, and what cleaning cannot fix
Some glass will not come back to clear no matter how it is cleaned, and it is better to know that before paying for a clean that expects a different result.
Wind-driven grit gradually abrades exposed glazing, and salt holds moisture and mineral deposits against the surface. Hard water running repeatedly off a sill or an air-conditioning unit leaves mineral deposits that bond to the surface. Fresh deposits a good clean will lift. Abrasion is different: once grit has scratched the surface the marks are in the glass rather than on it, and cleaning will not remove them.
Construction work causes the other common one. Concrete splatter, render and metal fragments baked on by the sun mean post-build glass often needs restoration rather than cleaning, and it should be dealt with promptly, because the longer it sits the less likely restoration is to work.
We will tell you which of those you are looking at when we quote. Where glass is past cleaning we will say so rather than charge for a result we cannot deliver.

Access and height
Ground floor and low-level glazing is straightforward. Above that, access is the thing that determines both method and cost: water-fed pole systems reach a good height from the ground and avoid ladders entirely, while genuinely high-level work needs proper access equipment and planning.
We will tell you at the site visit what your building needs, and where a section is beyond what we should be doing safely we will say so rather than improvise. Height work is one of the areas where a cheap quote usually means a corner is being cut.
What drives the cost
- Number of panes rather than area. Many small panes take far longer than the same area of large glazing, because the time goes into edges and frames.
- Access. Ground level, pole-reachable, or requiring equipment.
- Frequency. A quarterly cycle costs less per clean than an annual one, because there is less build-up each time.
- Internal, external or both.
- Frames and tracks. Included or glass only.
- Timing. Before opening or outside trading hours.

Frequently asked questions
How much does commercial window cleaning cost in Wellington?
It comes down to pane count, access and frequency rather than floor area. We quote after looking at the building, because a photograph does not show what the access is like.
Do you clean inside as well as outside?
Yes, and they are usually on different cycles. Interior glass and partitions typically need attention more often than exterior glazing in an office, and less often in retail.
Can you clean high-rise windows?
We cover ground and mid-level glazing, including pole-reachable heights. For genuinely high-rise abseil work we will tell you straight that it is a specialist job rather than take it on.
Will you work outside trading hours?
Yes. Retail frontage is normally done before opening. Our operating hours are Monday to Friday, 7am to 9pm.
What happens if it rains?
Rain on clean glass does not undo the work; it is the dust and salt on dirty glass that causes streaking. We will move a visit for genuinely unworkable weather or wind, and tell you when we do.
Can window cleaning be part of our cleaning contract?
Yes, and it is usually better that way. It sits as a scheduled periodic line alongside floor care, so the cycle actually happens instead of being remembered once a year.
