A window cleaning price depends mainly on three things. How many windows you have, how big they are, and what should be cleaned: glass only, both sides, or frames and sills too. At Spotless, window cleaning starts at €80 as a final price, and your exact price comes from an individual quote based on your windows and the scope you choose.
Below you will find what goes into the cost, how to compare offers and what to send for an accurate quote. Most of this applies no matter who you hire, so it should help even if you end up doing the job yourself.
What a window cleaning price usually covers
When people ask about the cost, they often picture a single pane of glass. In practice, a window job in a German apartment or office has more parts than that. There is the glass on the inside and outside, the frame around it and often a sill. Many homes also have a balcony or terrace door that gets just as dirty.
Typical parts of a window job are:
- Glass panes, on the inside, the outside or both
- Window frames and, if agreed, the sills
- Glass doors, balcony doors and terrace doors
- Conservatory glass that can be reached safely
Blinds, shutters and roller shutters are a different kind of work. They take time, they are dusty, and many providers price them separately. If you want them cleaned, mention it from the start so nobody is surprised later.
The point is simple. Two offers can show the same number and still describe very different jobs. Before you compare prices, compare what each offer actually includes.
The factors that shape the window cleaning price
Every quote is really an estimate of time and effort. The table shows the factors that matter most, why they change the effort and what to tell the cleaner.
| Factor | Why it changes the effort | What to tell the cleaner |
|---|---|---|
| Number of windows | More windows simply take more time | A count per room, including glass doors |
| Size of the windows | A floor-to-ceiling window takes far longer than a small bathroom window | Rough sizes or a photo of each window type |
| Number of sashes and panes | Windows with several opening parts or divided panes have more edges and corners | A photo that shows how the window opens |
| Inside, outside or both | The outside usually carries more street dust, pollen and rain marks | Which sides you want cleaned |
| Frames and sills | Frames collect dust, insects and grime in the corners | Whether frames and sills should be included |
| How dirty the windows are | A first clean after a long break, or after renovation work, takes longer | When they were last cleaned, plus photos |
| Access | Heavy furniture, plants or full window sills slow everything down | Anything that stands in front of the windows |
| Extras like blinds | Separate work with its own effort | Mention them as a separate item |
Imagine, for example, two apartments with the same number of windows. One is a modern flat in Bilk with large single panes and nothing in front of them. The other is an older flat in Pempelfort with divided panes, plants on every sill and a balcony door hidden behind a sofa. The window count is the same, but the second job will take noticeably longer, and a fair quote reflects that.
Choosing your scope: glass only, both sides or frames too
The scope is the part you control, and it has a big effect on the price. Here is how the usual options differ in everyday life.
Glass only, inside
This is the smallest job. It makes sense if the outside is cleaned by a building service or if you mainly want clear views between bigger cleans. It will not remove the weather film on the outside, though, so on a sunny day you may still see streaks.
Glass on both sides
This is what most people mean by window cleaning. Many German homes have tilt-and-turn windows. They open fully inward, so the outside of the glass can be cleaned from inside the room. That is safer and quicker than leaning out, but it still means opening every window and working around the hinges.
Glass, frames and sills
If the windows have not been cleaned for a while, the frames are often the dirtiest part. Clean glass inside a grey frame still looks unfinished. Including frames and sills adds time, but it is usually the scope people are happiest with afterwards.
Older buildings with box windows
In many older buildings in Düsseldorf, for example in parts of Oberkassel, you still find box windows (Kastenfenster). These have an inner and an outer window, which means four glass surfaces instead of two. If you live in an Altbau, mention this, because it changes the job more than people expect.
Why per-window prices online can mislead
When you search for prices, you will find plenty of numbers. Some are per window, some per pane, some per hour, some per square metre. None of them is wrong as such, but they are hard to compare. A low headline number does not always mean a low final bill.
A few things to check before you decide:
- Is the price per window, per pane or per side of glass
- Are frames, sills and glass doors included or extra
- Is the price a final price, or does VAT or anything else come on top
- What happens if you are not happy with the result
At Spotless we try to keep this simple. You choose the scope, we look at your details and photos, and you get one final price. As a small business under § 19 UStG we do not charge VAT, so the number in the quote is the number you pay. For window cleaning our insured team brings its own products, and eco-friendly products are available on request. If something is not right after the visit, you can tell us within 24 hours and we come back to fix it free of charge. We are a young company, and fair prices with a clear guarantee are how we want to earn trust.
How to get an accurate quote quickly
Many delays and surprises with window cleaning come from missing information. A few minutes of preparation give you a quote that matches the real job.
- Count your windows and glass doors, room by room. Note any very large or unusual ones.
- Take a photo of each window type, ideally one that shows how it opens and what stands in front of it.
- Decide on the scope. Inside only, both sides, or with frames and sills. Mention blinds separately if you want them done.
- Add practical details such as which floor you live on, whether there is a balcony or conservatory, and which days or times suit you.
With this, you can request a free, non-binding quote based on your information and photos. Cleaning appointments can be at any time, including early mornings, evenings and weekends. That helps if you work during the day or run an office that should not be disturbed. You can reach us Monday to Sunday from 08:00 to 16:00.
One more tip. If you already have regular cleaning or plan a deep clean or a move-out clean, ask for the windows as an add-on in the same request. It saves you a second appointment and makes the planning easier on both sides.
Doing it yourself or hiring someone
Cleaning windows yourself is cheaper in money and more expensive in time. For a small apartment with a few windows, many people manage well on their own. A few habits make a real difference.
- Clean on a cloudy day or when the sun is not on the glass, so the water does not dry into streaks.
- Do the frames first, then the glass, so dirt from the frame does not run onto clean panes.
- Use a squeegee and a dry microfibre cloth for the edges instead of paper towels.
- Never lean out of an open window or stand on a chair at an open window. If you cannot reach it safely from inside, leave it.
Hiring someone makes more sense when there are many windows or very large panes. The same goes for when you have no free afternoon, or after a move or renovation. It also helps older people who would rather not climb step ladders. Families and pet owners often see small hand and nose prints on the terrace door every week. For offices, shops and practices, it is often less about money. What matters is clean glass at the entrance without staff doing it between other tasks.
Whichever way you go, the honest answer about the price stays the same. It depends on your windows and your scope, and a good quote should explain both.
