#1 office cleaning company in Tallinn
Apartment building stairwell cleaning
Kontorikoristus 24 cleans the stairwells of apartment associations in Tallinn and Harju County on the basis of a contract, and this service is part of our stairwell and common area cleaning. Each visit covers steps, stair treads, handrails, elevator buttons, mailbox area and front door handles, plus the entrance mat behind the front door in winter.
The contract is concluded with the apartment association, not with individual residents: the board approves the cleaning frequency and price based on the decision of the general meeting, and the apartment association receives one monthly bill for payment by bank transfer. At the end of 2025, there were 29 apartment associations with 76 staircases in the contract.

When an apartment association needs stairwell cleaning
Residents’ cleaning rota is no longer working
In a building with twenty apartments, each apartment's turn to wash the stairwell only takes place every 20 weeks, and one missed week shows up immediately: the sand crunches underfoot on the first floor mat and the handrail is sticky to the touch. Two empty weeks on the bulletin board's schedule page in one month means the volunteer schedule is over and the stairwell needs a regular cleaner.
White salt residue remains on the lower steps
From November to March, shoes bring salt and grit to the stairwell. The white edges on the lower steps after drying means that the weekly washing will no longer remove the salt, and two visits per week are necessary for the winter, which will prevent the salt from etching the surface of the steps.
Apartment renovations bring dust into the stairwell
During the repair of several apartments at the same time, the builders carry plaster and tile cutting dust on the stairs with their shoes, and a gray trail is formed from the door to the front door of the apartment and a layer of white dust on the handrail. After the repairs are complete, the board orders a one-time deep cleaning of the stairwell and the stairwell goes back to a weekly schedule.
Why Salt and Sand Wear Out Stairs
The salt sprinkled on the sidewalks dissolves in the snowmelt water and seeps into the pores of the concrete or mosaic concrete of the steps with the water. In a warm stairwell, the water evaporates, the salt recrystallizes inside the pores, and the growing crystals break the surface in thin layers, so by the end of winter, the first stairwell becomes rough and gray and traps dirt.
Sand and grit are harder than the marble chips of mosaic concrete, so every step that turns a step against a pebble will sand the surface like sandpaper. The edge of the steps and the floor by the front door, where the sand brought from the shoes remains, wears out the most, and that is why the sand is wiped dry before wet washing, instead of being spread along the steps with a wet mop.
How apartment association Staircase Cleaning Works
Inspection and checklist
the site supervisor checks the floors, apartments and stairwells, checks whether the steps are made of mosaic concrete, ceramic tiles or painted concrete, and notes on the checklist where the cleaner gets water and where the used washing water is poured. At the same inspection, he measures the floor by the front door to determine if the stairwell needs an entrance mat for the winter.
Dry clean before washing
The cleaner starts from the top floor and first sweeps up the sand and debris with a brush, because a wet mop drags the grain of sand along the step and scratches the area. Then, the steps and mats are washed with a pH-neutral product with a flat microfiber mop, the washing water is changed every two floors.
Touchpoints and visit log
Finally, the entire length of the handrail, elevator buttons, mailbox fronts, and exterior and basement door handles are wiped with a disinfectant. The cleaner writes the date and time on the guest sheet on the stairwell notice board, so that every resident can see when the stairwell was last washed.

Tallinn Panel Houses Winter Entrance
The sidewalks in front of Lasnamäe, Mustamäe and Õismäe panel houses are maintained in winter by the apartment association's own maintenance company, and the more salt and grit are sprinkled in front of the front door, the more they are carried to the stairwell. In winter, Kontorikoristus 24, in addition to the staircase, also sweeps the wind room and the front steps of the front door, because every handful of sand swept up from there does not reach the steps anymore, and gives the board a written recommendation on where to place the bulk material box so that it does not end up right in front of the door. In the Kontorikoristus 24 graph, there were 56 stairwells in these three districts at the end of 2025.

Frequently asked questions
Can residents see what the cleaner has done?
Yes, the cleaner writes the date and time of each visit on the stairwell visit sheet. Once a month, the stairwell checklist is signed by the site supervisor, and the board receives a copy of it along with the monthly bill.
What happens to bicycles and prams left in the stairwell?
The cleaner does not move the belongings of the residents, but washes around them and notes on the visit sheet which floor the items prevented from being washed. The stairwell is the house's escape route, and based on its signs, the board asks residents to move items to the storage room.
Does the cleaner bring equipment and water?
The cleaner brings washing tools, mops, buckets and cloths with him, he takes water from the house's water intake point, which is noted on the checklist during the inspection. One visit to the five-story stairwell requires 30 liters of water, or three buckets, because the washing water is changed every two floors.
Can we increase the cleaning frequency in winter?
Yes, based on the written notice of the board, there are two visits a week from November to March and once again from April. Billing is done monthly and the contract has a one-month notice period, so the change in frequency takes effect from the next billing period. In November 2025, the second winter visit was to 14 stairwells.
