Window cleaning essentials
What is included in professional window cleaning?
Top Notch Exterior Cleaning · 5 min read · 8 November 2026
A professional window clean covers the glass on both sides where quoted, plus the frames and sills. Screens, sliding-door tracks and hard-water removal are usually quoted separately because they take real time. The scope should be listed in writing, so you know exactly which windows and which surfaces are covered before the visit.
The short answer
A properly scoped professional clean includes the glass, the frames and the sills. Interior glass is included only when it is in the quote. Screens, tracks, balustrades and heavy mineral removal are separate items.
The value of a professional clean is not just cleaner glass. It is that the window as a whole — pane, frame, sill, edges — is finished, so it looks right from the street and from inside the room.
What is normally included
Exterior glass
Every accessible exterior pane, washed and squeegeed rather than wiped. Wiping leaves a film that shows in low light; a proper squeegee finish does not.
Interior glass, when quoted
Inside work is slower and needs care around furniture, blinds and floors. If the quote says interiors are included, they are. If it does not, ask.
Frames and sills
Clean glass in a grimy frame still looks unfinished. Frames are wiped as part of the job, and sills are cleared of dust and debris so water does not pool and leave marks.
Glass doors and large openings
Sliding doors, stackers and bifolds are part of the standard clean where they are accessible, though the tracks take extra time and are usually priced separately.
A proper finish check
A good cleaner checks the glass before packing up, rather than discovering streaks after leaving.
What is usually quoted separately
- Flyscreens, which are washed individually
- Sliding-door and window tracks, which need vacuuming and detail work
- Glass balustrades, pool fencing and balcony glass
- Hard-water film and mineral deposits from sprinklers
- Paint, silicone, render or construction residue
- Windows above three storeys, which many Melbourne cleaners do not service at all
How the work is actually done
There are three common methods, and the right one depends on the glass and the access:
- Hand wash and squeegee for interior glass, detail areas and smaller panes
- Water-fed poles with purified water for exterior glass at height
- A combination of both on larger properties
Purified water dries without spotting, which is why it is common on exterior glass. Interior glass is almost always done by hand because water control matters more indoors.
What professional cleaning will not fix
It is worth being honest about limits:
- Etched glass from long-term mineral exposure cannot be polished back by cleaning
- Scratches from previous grit or blades stay scratched
- Failed double-glazing seals, where moisture sits inside the unit, cannot be cleaned out
- Painted or frosted surfaces need different treatment and should be flagged before the visit
Knowing this before you book avoids disappointment. A good cleaner will point it out at the quote stage rather than after.
How to check a quote covers what you think it does
Ask three questions:
1. Which windows are included — all of them, or the accessible exterior ones?
2. Are frames and sills included, and are screens and tracks included or extra?
3. Is interior glass part of the price?
If the quote answers those, the two prices you are comparing are actually comparable.
Why this matters for the result
The most common complaint about window cleaning is not dirty glass — it is a clean window that still looks unfinished because the frame is grubby or the sill has a line of dirt on it. The second most common is streaks on interior glass from a cloth finish.
Both come down to scope. A quote that lists what is included gives you a result you can judge fairly.
Frequently asked questions
They should be. Frames and sills are part of the service because clean glass in a dirty frame still looks unfinished. If a quote excludes them, that is worth knowing before you compare prices.
Screens are usually washed in place or removed, washed and refitted, and quoted as an addition. Mention them when you enquire so they are priced rather than skipped.
Light mineral film usually lifts with a targeted treatment. Long-term etching, where the glass itself has been marked, will not come out through cleaning — and it is better to know that upfront.

How to choose a reliable window cleaning company in Melbourne
Choose a window cleaner on four things: a written scope, a straight answer about access and height limits, evidence they carry insurance, and a quote you can compare line by line. Price matters, but a cheap quote that excludes frames, interiors or second-storey glass is not a cheaper job — it is a smaller one.

Window cleaning in Melbourne is priced per property, not per window, because the work depends on glass size, storeys, access and how much build-up has to come off. A single-storey home cleaned outside only costs less than a two-storey home cleaned inside and out. Quotes are free, and the only reliable price is one based on your actual property.

Cleaning your own windows works well for ground-floor glass you can reach safely and clean quickly. It stops working at height, on large panes, on second storeys and on glass with hardened build-up. Professional cleaning is about safety, equipment and a streak-free finish — not about a job you could never do at all.
Read articleStrata6 minHow often should strata buildings schedule window cleaning?
Most Melbourne strata buildings clean common-property glazing two to four times a year. A quarterly program keeps a street-facing building looking maintained all year; six-monthly suits smaller or sheltered buildings. The right frequency depends on street exposure, glazing area and how the building is presented to owners and visitors.
