Everyone asks this first, and nobody can answer it honestly in one line. Window cleaning has no catalogue price, for the same reason a house move has none: it is not a product, it is working time applied to one specific situation. This guide explains what is common in Belgium, where the figures come from, and how to read a quote without being caught out by a headline price.
What Belgian sources publish
The figures below come from publicly available Belgian pages, consulted on 30 July 2026. They are not Clair et Net's rates, and they are not an official industry average. Treat them as orders of magnitude.
Quote platform Bobex, page "De prijs van een ruitenwasser"
| Situation | Published range |
|---|---|
| Hourly rate for a window cleaner | €20 – €55 / hour |
| Terraced house | €15 – €35 |
| Semi-detached / three-façade house | €25 – €40 |
| Detached house | €35 – €50 |
| Businesses (café, restaurant) | €45 – €90 |
The same page cites an average pace of roughly 75 m² of glazing per hour, which explains why surface area weighs so heavily in a quote.
Platform Yoojo, Belgian guide on domestic window cleaners
Yoojo describes pricing per square metre: €1.50 to €2.50 / m², rising to around €6 / m² for conservatories where access is difficult. The guide also estimates 2 hours 30 for ten windows, roughly twenty minutes per window.
Two reading rules that matter. Yoojo also gives an average hourly rate of €14 / hour on its platform. That figure is not comparable with a company's: it reflects matchmaking between private individuals and independent providers, with a different cost base, different equipment and different cover. Separately, other Belgian sites quote higher ranges — in the region of €2 to €5 / m², or €100 to €250 for a whole house. Those figures circulate, but we had not verified them page by page at the time of writing, so we cite them as secondary reference points only.
Why none of these figures settles your job
Take two detached houses with the same glazed area. In the first, every window is reachable from level ground. In the second, a six-metre pane sits above a bank and there is a conservatory with a glass roof. The "€35 – €50" range says nothing useful about the second.
What actually drives the number:
- Number and size of panes. Ten small glazing-bar panes take longer than three large panes of the same total area.
- Which faces. Outside only, inside only, or both. Adding the inside can more than double the time: entering, protecting, moving things, closing up again.
- Height and access. A pole from the ground costs working time. A powered access platform costs hire, positioning, and sometimes a permit to occupy the pavement.
- Level of soiling. Glass maintained three times a year is not glass left four years on a busy street.
- Requested finish. Frames, casings, sills and vents are separate items, not a detail of the glass.
- Frequency. A one-off visit carries the travel and set-up on its own.
- Site logistics. Parking, badge, lift, imposed hours, a manager who has to be present.
What about service vouchers (titres-services / dienstencheques)?
In Belgium, cleaning the windows of a private home can in some cases be done through the service voucher scheme by an approved company. Public information consulted indicates the scheme covers both inside and outside faces, with safety restrictions — notably no ladders beyond a few steps — and that one voucher corresponds to one hour of work, purchased for around ten euros, varying by Region. Each of the three Regions runs its own scheme and conditions.
Two practical consequences: the scheme is reserved for private individuals resident in Belgium, and it does not cover work at height or professional contracts. Conditions change regularly — check with your Region's authority before relying on it.
Reading a quote properly
An honest quote lets you answer four questions without picking up the phone:
- Which faces are included? "Window cleaning" says nothing about inside or outside.
- Are frames and sills in it? Those are three different things.
- Which limits are stated? Baked-on limescale, paint or cement splashes, already-etched glass.
- What would trigger a supplement? Unexpected access, soiling far beyond the photos, height equipment not anticipated.
A low price with no answer to those four questions is not a low price. It is an incomplete one.
Our position
We publish no universal rate, because an honest universal rate does not exist in this trade. We ask for a few photos and some targeted information, then write down what is included, what is not, and at what price. If the photos are not enough, we propose a site visit rather than a number picked at random.
FAQ
Can you give me a price over the phone? An order of magnitude, sometimes. A firm price only after seeing the surfaces and the access, in photos or on site.
Why do online prices vary so widely? Because they describe different things: private-individual platform or company, one face or two, with or without frames, from the ground or at height.
Does the price drop if I book more often? The price per visit usually drops, because travel is spread and the glass is less soiled. The annual budget depends on the frequency you choose.
