Four types of window and glass cleaning

During the inspection, the site supervisor notes what kind of window and glass cleaning the building needs: window cleaning at heights, regular window cleaning, glass facade cleaning or glass partition cleaning. From the first contract through the end of 2025, there were 1,062 window and glass cleaning orders: 581 window cleaning, 268 glass partition cleaning and 213 rope access facade washing.

  • The window cleaner washes the high windows of the light-colored building from the basket of the basket lift, the glass with self-cleaning coating is not touched with a metal blade.

    High-level window cleaning

    window cleaning at heights cleans the windows and glass facade of the upper floors of the office building, choosing the technology according to the height of the building: water washing telescopic pole system on lower floors, rope access technology at a height of more than 12 meters, where the system with the arm can no longer reach to clean effectively.

    Kontorikoristus 24 assigns one contact person to each order placed at heights, who will agree on a weather window with the management company and confirm which windows open for cleaning from the inside and which require external access.

  • The glass cleaner washes the glass wall of the meeting room with a squeegee and cloth, the chairs are pushed under the table before washing so that the squeegee reaches the lower edge of the wall.

    Regular window cleaning

    Regular window cleaning keeps the glass surfaces of the office building transparent at an agreed frequency, at street level and on lower floors, where dust and splashes accumulate faster than on higher floors.

    Kontorikoristus 24 uses a 20-liter deionized water tank for regular washing, which is connected to a 9-meter long extension arm, so that the glass dries automatically without streaks after washing, without the need to touch the glass with a cloth.

  • The window cleaner washes the upper part of the glass facade of the building with a long handle from the ground, in 2025 there were 71 orders for window cleaning from the ground with a handle.

    Glass facade cleaning

    The glass facade wash covers the glass panels of the exterior wall of the building from the aluminum frames to the edge, removing bird dust, dust and calcium residues from rain marks, which the rain does not wash off from the smooth glass.

    the site supervisor also notes the condition of the facade glass on the monthly checklist and writes down every panel that needs a maintenance visit by the manufacturer.

  • The cleaner washes the window with a white frame above the radiator with a squeegee and cloth, the rubber of the squeegee is changed every 3 months, because the worn edge leaves a streak on the glass.

    Glass partition cleaning

    The washing of glass partitions cleans the glass walls of meeting rooms and open offices from fingerprints and marker residues with a scraper and microfiber cloth.

    An oil-based marker mark on a glass board needs a solvent, because a board washed with ordinary window cleaner leaves a film that makes the next letter cloudy.

Window and glass cleaning prices

The price is calculated according to the square meters of the glass surface and the difficulty of access.

ServicePrice
Window and glass cleaningFrom €1.00/m²
Glass partition and board cleaningFrom €0.80/m²
Glass facade cleaning with rope accessFrom €2.60/m²
Additional window cleaning visit outside the main scheduleFrom €28/hour
On-site glass measurement0 €

The main factors affecting the price:

  • building height: telescopic pole system versus a facade requiring rope access
  • amount of glass surface in square meters and opening method of windows, internal or external cleaning
  • washing frequency: once a quarter versus monthly regular washing
  • type of dirt, calcium residues need acid cleaning, dust just water
  • a weather window that limits the timing of rope access operations due to wind and precipitation
  • permission from the management company for access to the roof during the rope access works

How long does window cleaning take?

90 square meters of glass surface at street level takes 2 hours for two window cleaners with a telescopic pole system, because drying the area with deionized water does not require subsequent washing with a cloth.

Washing the glass facade of a 12-story building with rope access takes two technicians 1 working day, and the day starts with checking the rope attachment points on the roof before descending.

Washing the glass partitions in an office space with 15 meeting rooms takes one cleaner 50 minutes, because the marker residues must first be softened with a solvent before wiping.

The technician attaches the work and safety ropes to two separate anchor points, and a 5-meter danger zone is demarcated on the ground with tape. In 2025, rope access technicians washed 31 glass facades with a total of 18,972 square meters.

A cleaner with a window squeegee and sprayer in the office next to a stack of cloths, a glass cleaner reaches the top edge of the high glass partitions with a squeegee with a handle and does not step on tables or chairs.
The cleaner scrapes the glass wall of the empty meeting room with a squeegee, which partly still has marker marks, and railway tracks are visible from the large windows, the glass cleaner wears nitrile gloves to avoid fingerprints on the freshly washed glass.

How the service works

Three steps from the inquiry to the first glass cleaning visit.

  1. 1. Inspection and Access Assessment

    the site supervisor visits the building, measures the glass surface and decides whether a telescopic pole system is sufficient or whether rope access is needed. Access to the roof and the availability of attachment points will be checked before the quote is prepared.

  2. 2. Schedule and Price Agreement

    The price is determined by the square meters of the glass surface and the washing frequency, which the site supervisor records during the inspection. In the case of rope access, a separate weather window is added, during which the work is carried out on the first suitable day.

  3. 3. First clean and checklist

    On the first visit, the site supervisor notes the condition of the glass surfaces and the type of dirt on the checklist, so that on the next visit, the cleaner knows in advance whether acid cleaning is needed or the usual one is sufficient.

How to choose the frequency of window cleaning

The frequency is determined by the floor, the proximity to the street and the visibility of the glass from the reception area.

Monthly cleaning for reception area glass

The glass walls of the entrance and reception area, which are the first to be seen by guests, are washed once a month with a squeegee and microfiber cloth, as fingerprints and dust stand out there the most.

Quarterly cleaning for upper-floor windows

Windows on higher floors, which are less exposed to street dust, are washed once a quarter on a dry, calm day, which is suitable for extension rods and rope access.

Twice-yearly cleaning for facades away from the street

Facades that do not remain on the street and have a lower dust load are suitable for two washes a year, in spring and autumn, in the months between the dusty summer and salty winter periods.

Frequently asked questions

How high can you clean with a telescopic pole?

The deionized water telescopic pole system reaches a height of 9 meters. At a height of more than 12 meters, we switch to a rope access technique, as the system with a stem no longer presses against the glass with sufficient force.

Why use deionised water instead of tap water?

Deionized water does not leave mineral streaks on the glass because lime and salts have been removed. The glass dries by itself after washing, without the cleaner having to go after the glass with a cloth.

Does the weather affect window cleaning?

Yes. Facade works with rope access are not carried out in wet and windy weather, because then it is not safe to work on the roof and facade. Washing on the ground with a telescopic pole can be done in any weather, except for strong winds.

Do you remove marker marks from glass boards?

Yes, the washing of glass partitions and glass panels uses a separate solvent for the oil-based marker, and not the usual window cleaner, because the wrong tool will blur the writing mark.

How much does window and glass cleaning cost?

window and glass cleaning starts at 1.00 euros per square meter. Cleaning a glass facade with rope access costs from 2.60 euros per square meter, as it requires two technicians and approval of access to the roof.

Do you clean stairwell and common area windows?

Yes, the windows of the stairwell and common areas are part of stairwell and common area cleaning, which is ordered by the apartment association or the management company by separate agreement.

Do the windows need to open?

No, we clean the glass on higher floors and the facade from the outside with a telescopic pole or rope access, regardless of whether the window opens from the inside. In the case of internal glass partitions, normal access to the room is sufficient.

Which areas do you serve for window and glass cleaning?

We wash glass in Tallinn office buildings from Ülemiste to central Tallinn and in cooperative buildings in Mustamäe and Lasnamäe, as well as in Harju County Maardu, Viimsi, Rae Parish, Keila and Saue. There is no travel charge in Tallinn, and it is 0.70 euros per kilometer at the sites in Harju County.
