Dirty windows can spoil the impression of even the most tidy apartment or representative office. In Prague, the combination of construction dust, traffic on main roads and humidity from the Vltava river contributes to this, so that even carefully washed windows lose their shine faster than one would expect. This guide will show you how window cleaning in Prague actually works, how much it costs, when it is worthwhile to use a robot for window cleaning or work at heights, and how to choose a supplier that you can trust even in a year.
Whether you are dealing with a one-off window cleaning after the renovation of an apartment, or you are looking for a regular service for an administrative building, you will find specific numbers, a practical checklist and answers to the questions that people ask themselves most often.
What is professional window cleaning and how is it different?
Professional window cleaning is not just washing the glass with a rag and a window. It includes the cleaning of frames, windowsills (interior and exterior), seals and, for some types of windows, the removal of accessories such as blinds or insect screens. The goal is not only to polish the window, but also to remove deposits that cannot be removed by hand washing with a household window bottle.
In addition, professionals work with technology (squeegees, purified water systems, osmotically purified water on rods at high altitudes), thanks to which the windows do not dry with streaks, even in sunny weather, when amateur washing usually turns out poorly.
Hand wash vs. washing windows with a robot
In recent years, the window cleaning robot has been gaining ground in Prague – a small device with suction cups that moves around the glass and cleans it using rotating felt discs. Companies use it mainly where it is difficult for an ordinary worker to reach safely or quickly.
- Hand wash is still the standard for ordinary windows in apartments, family houses and ground-floor offices - it allows you to thoroughly clean frames and windowsills.
- Robotic washing suitable for glass walls, atriums, high-rise buildings or large office complexes where scaffolding or climbing equipment would make the job more expensive.
- A combination of both is common practice: a technician washes manually accessible windows while simultaneously operating one or two robots on hard-to-reach areas.
What types of windows are washed most often in Prague?
Prague's built-up area is varied, which is why companies come across several different types of windows:
How much does window cleaning cost in Prague?
The price in Prague is usually calculated in two ways: a flat rate per square meter or an hourly rate for the technician's work. For larger orders (companies, apartment buildings) an hourly rate combined with the number of deployed robots is more common, while for households the price per m² or for the entire order is more common.
| Type of service | Indicative price | Note |
|---|---|---|
| Washing windows in the apartment (manual) | About 12–20 CZK/m² | Includes glass, frames, windowsills |
| Window cleaning - technician's hourly rate | About 250–350 CZK/hour | Common in companies and offices |
| Height washing of windows (facades, atria) | Individual calculation | It depends on the approach and technique |
| Cleaning blinds (per piece/m²) | About 20–40 CZK/lamella or m² | The price increases with the difficulty of disassembly |
What affects the price the most
- Accessibility of windows (ground floor vs. height, balcony vs. deep facade).
- Degree of pollution - after reconstruction or after winter, the price is higher due to the necessary pre-cleaning.
- The number of windows and whether the washing of blinds or nets is also ordered at the same time.
- Frequency – companies that order a regular service (e.g. twice a year) usually get a better price than a one-off order.
If you are planning a more regular collaboration, it makes sense to look directly at the overall price list of cleaning services, where window cleaning is included as an additional item to regular cleaning.
Height window cleaning
Administrative buildings, glazed entrance halls or residential houses with a facade facing the street simply cannot do without high-level window cleaning. Common practice for office buildings is to wash the facade approximately twice a year, in exposed locations (busy streets, construction activity in the vicinity) even more often.
Safety, certification and insurance
Work at height is subject to strict safety standards. When choosing a supplier, it is wise to ask about:
- valid certificates for working at heights (climbing technique, mountaineering courses),
- liability insurance,
- experience with a specific type of facade (an all-glazed wall is handled differently than a classic window with a parapet).
A window cleaning robot as a safe alternative to work at height
Where a climbing team or scaffolding had to be used before, nowadays a window cleaning robot controlled from the ground or from a window is more and more often sufficient. The advantage is obvious: lower risk of injury, faster deployment, and often lower cost, as time is eliminated for building security. The disadvantage is that the robot needs a flat glass surface without large obstacles (window sills, protrusions), so it cannot always be used universally - for more complex facades, it is often combined with classic height technology.
Cleaning blinds
Cleaning blinds is often only solved when one realizes that the "white" slats are actually gray. Dust and grease settle mainly in the gaps between the slats and on the fastening mechanisms, where you cannot practically reach with a normal cloth.
Types of blinds and how to care for them
- Horizontal blindsMost common in offices – slats are cleaned slat by slat, ideally without disassembly, if the structure allows it.
- Vertical blindsCommon with large glass surfaces, more susceptible to dust collection due to vertical orientation.
- Fabric and pleated blindsThey require a gentler approach, they are often cleaned with the help of special vacuum cleaners or steam.
In addition, regular cleaning of the blinds is worth combining with general window cleaning - companies usually offer this as a single order, since the disassembly and assembly of the blinds is done together with the washing of the glass behind them anyway.
When does it pay off for wider cleaning services in Prague instead of one-off window cleaning?
If you are dealing with only one event (e.g. washing windows after painting), a one-off order makes sense. However, when it comes to an office, shop or apartment building, it is usually better to agree on a regular service as part of wider cleaning services in Prague, because the supplier knows the space, has a set schedule and deals with windows along with other tasks (cleaning common areas, cleaning carpets, disinfection).
Households vs. companies and offices
| Criterion | Household | Company / office |
|---|---|---|
| Window cleaning frequency | 1–2 times a year | 2–4 times a year, depending on the exposure of the building |
| Order type | Disposable | Contractual, regular |
| Frequent additional services | Washing windowsills, blinds | Carpet cleaning, office cleaning, disinfection |
| The deciding factor | Price, speed | Reliability, reporting, contract |
Companies that deal with regular office cleaning often associate window cleaning with the order cleaning of offices and companies, so that they have one supplier for everything and do not have to coordinate several companies at once. It works similarly with SVJ and apartment building managers, where the washing of the windows of common areas is typically agreed together with cleaning apartment buildings and apartment buildings.
The Prague scene: where window cleaning is most often done
Prague is not a homogenous city and the demand for window cleaning varies by district:
Historic houses with casement windows, where a more gentle approach is needed and often also work with wooden frames.
Housing estates with panel houses, where the main task is to wash the windows of common areas and loggias, usually via SVJ.
Modern administrative complexes with glass facades, ideal candidates for high-altitude window cleaning and the deployment of robots.
Family houses and villas with large windows to the garden, where the washing of greenhouses and conservatories also plays a role.
This diversity is one of the reasons why it pays to look for a contractor in Prague who has experience with several types of construction at once, not just one segment.
How to choose a window cleaning company in Prague
Before choosing a supplier, go through this short list:
- ReferencesDoes the company have references for a similar type of building (apartment, office, block of flats)?
- A combination of methodsDoes it offer a combination of hand washing and robots, or just one method?
- Transparent priceIs the price set transparently (per m² or per hour), or do you just get a flat rate without a breakdown?
- Certification and insuranceIs the work at height technician certified and insured?
- Cleaning blindsDoes the company also deal with the cleaning of blinds as part of the same order?
- Regular serviceDoes it offer regular service at a discount compared to a one-off order?
- AvailabilityHow quickly can he start and what references does he have from companies in your location?
Practical tips to keep your windows clean for longer
- Wash windows in cloudy weather - in direct sunlight, water dries faster and streaks remain.
- Wipe down the inner windowsills at least once a week, this will prevent the accumulation of dust, which then also sticks to the glass.
- Clean the blinds with a dry cloth on an ongoing basis, leave the deep cleaning of the blinds to professionals once or twice a year.
- For flats on the ground floor and near the street, expect that the windows get dirty faster due to dust from traffic - adjust the frequency of washing accordingly.
- If you are considering a window cleaning robot for home use, check the load capacity of the suction cups on your type of glass and whether it can cope with minor irregularities in the frame.
Frequently Asked Questions (FAQ)
How often should office windows be washed?
The standard is usually twice a year, for exposed buildings (busy street, construction activity) even four times a year.

Recommendations
Window cleaning in Prague is not a universal service, a casement window in Vinohrady, a glass facade in Karlín and a block of flats in Jižní Město each require a slightly different approach, technique and frequency. Knowing what to ask the contractor and knowing the realistic price range will make your choice much easier and you won't be stuck with a vague flat rate without a job breakdown.
