Office deep cleaning in Tallinn and Harju County

Kontorikoristus 24 performs major office cleaning in Tallinn and Harju County office premises and goes deeper than maintenance cleaning: ventilation grates, cable ducts, inside cabinets and office chair fabric, which are not covered by the maintenance cleaning schedule. Deep cleaning covers disinfecting deep cleaning, cleaning after moving, office chair upholstery cleaning and dust removal of high surfaces.

In an office with closed ventilation, the air changes more slowly than in an open space, so Kontorikoristus 24 uses a vacuum cleaner with an H13 HEPA filter, which captures fine dust and does not blow it back into the air. In the quote, the site supervisor writes the square meters measured on site in the office and the agreed scope, no fee is charged for the inspection. There were 711 major cleanings from 2009 to the end of 2025, 91 in 2025.

What office deep cleaning covers

Disinfectant deep cleaning, post-move cleaning, office chair upholstery cleaning and dust removal of high surfaces are carried out by the evening crew after the last employee has left or on Saturday. Of the 91 major cleanings in 2025, 41 were office major cleanings, 26 post-move cleanings, 13 disinfecting deep cleanings and 11 office chair cleanings.

  • The cleaner wipes the desktop in the glass-walled office with a sprayer and cloth, the circle goes clockwise in each room so that no handle is missed.

    Deep cleaning and disinfection

    Disinfectant deep cleaning applies the disinfectant to all touch surfaces, door handles and keyboards, and the agent remains on the area for the contact time specified by the manufacturer, before wiping dry.

    The contact time of the agent used by Kontorikoristus 24 is 5 minutes: if you wipe earlier, some microorganisms survive, if you wipe later, the agent starts to dry on the area and leaves a stain, so every surface remains wet for the entire contact time and is wiped dry only after it ends.

  • Stacks of moving boxes and a ladder in the office area under the large windows, during the cleaning after the move, the places of furniture marks left in the carpet are steamed up.

    Office cleaning when moving

    Post-move office cleaning prepares the empty office space for a new tenant or hands over the space of the departing tenant to the owner, going through cabinets, cable routes and behind baseboards that are not covered by normal maintenance.

    Kontorikoristus 24 uses a 42-point handover checklist during the post-move-in visit, which goes through room by room, so the result is verifiable for both the owner and the new tenant.

  • Extraction cleaning of the office chair with a textile cover, the backrest is cleaned before the seat, so that the water spilling from it does not leave a border on the seat.

    Upholstery cleaning for office chairs

    office chair upholstery cleaning sprays a hot solution into the textile cover and sucks it out along with sweat, dust and coffee stains.

    Kontorikoristus 24 cleans the chairs during an evening visit because the fabric dries in 3 hours after extraction and the chair is ready for use in the morning.

  • The cleaner cleans the air hole at the top of the wall with a brush with an extension handle, the dusty ventilation grate reduces the air exchange in the room.

    High-level dust removal

    High surface dust removal covers cabinet and shelf ends, light housings, ventilation grilles and cable duct tops, where dust accumulates unnoticed for months until the air flow finally disperses it back into the room.

    Kontorikoristus 24 removes dust from high surfaces with a 3-meter extension wand HEPA filter vacuum cleaner, as the dry brush disperses the dust into the air and the vacuum cleaner sucks it into the bag.

How long does a deep cleaning of the office take?

A large-scale cleaning of a 200-square-meter open office space with 25 workplaces and two meeting rooms takes 5 hours for two cleaners, because the large-scale cleaning also covers the ends of the shelves and cable ducts, which are not touched by maintenance cleaning.

Disinfectant deep cleaning in an office with 15 workplaces takes 40 minutes, because during the 5-minute contact time of each room, the cleaner already disinfects the next room.

Dry cleaning of 20 office chairs takes one cleaner 2 hours, and the textile cover dries in 3 hours after extraction, so it is done in the evening after the last employee leaves.

Post-move cleaning of 150 square meters of empty office space, including closets and utility room, takes 4 hours for two cleaners and ends with filling out a 42-point handover list, which is signed by the site supervisor. 613 of the 711 major cleanings were completed in one evening or one Saturday, and in 2025, 1,147 office chairs were cleaned.

How the service works

Three steps from site inspection to complete deep cleaning.

  1. 1. Site inspection and scope

    The site supervisor goes over the office space and together with the client determines what is included in the scope of the deep cleaning: either only disinfection and high surfaces, or also office chairs and cupboards. The letter also states the specifics of the client's own waste system.

  2. 2. Schedule around office hours

    Larger cleanings are planned for the evening or the weekend, especially for office chairs that need drying time before the morning. The price including the scope will be confirmed in writing before the work starts.

  3. 3. Cleaning and signed checklist

    In each room, the HEPA vacuum cleaner with a 3-meter extension wand first empties the ventilation grille and cable ducts, before the cleaners reach the desks, chairs and floor. At the end, the site supervisor goes over the result with the checklist and signs it, leaving a copy for the client.

How to Choose the Frequency of a Deep Clean

The frequency is determined by the type of office and the number of guests in the meeting rooms.

Quarterly cleaning for offices with frequent visitors

The office, whose meeting rooms are frequented by clients and partners every day, orders a deep cleaning once a quarter, so that high surfaces, glass and textiles are uniformly tidy, not just the reception area.

Twice-yearly cleaning for a typical office

For offices with infrequent visitors, deep cleaning twice a year, in spring and autumn, alongside maintenance cleaning is suitable.

One-time cleaning in case of moving

When moving, a deep cleaning is a one-time order to transfer the premises vacated by the tenant to the owner or to prepare the new surface before moving in, separate from the regular maintenance schedule.

Frequently asked questions

How does office deep cleaning differ from regular cleaning?

Maintenance cleaning covers daily surfaces based on a specific schedule, deep cleaning also reaches ventilation grilles, cable ducts, inside cabinets and the fabric of office chairs, which maintenance cleaning does not touch.

Why use a HEPA-filter vacuum?

The H13 class HEPA filter captures fine dust and does not blow it back into the air in the room, which is important in an office with closed ventilation, where the air does not change as quickly as in an open room.

Must disinfectant remain wet during its contact time?

Yes. Contact time is 5 minutes. When wiping earlier, some microorganisms survive, when wiping later, the product starts to dry on the area and leaves a stain, therefore every surface remains wet for the entire contact time and is wiped dry only after it ends.

When can office chairs be used after cleaning?

The textile coating dries in 3 hours after extraction cleaning. Therefore, we plan the cleaning of office chairs for an evening visit, so that in the morning the chair is already dry and ready for use.

What is included in move-related cleaning?

Post-move-in cleaning goes through a 42-point handover list that covers inside cabinets, cable runs, behind baseboards and utility room, so that the area is verifiably clean for both the departing and incoming tenant. From 2009 to the end of 2025, there were 194 post-move cleanups and a total of 8,148 completed points in their lists.

How is waste from a deep clean removed?

Residues created after moving and cleaning the inside of cabinets, such as old documents or unused equipment, are sorted and removed according to the client's own waste system, as different offices have different agreements with recycling.

How much does office deep cleaning cost?

Major office cleaning starts at 2.00 euros per square meter. Ordered additional works are added to the final price: office chair dry cleaning 8.90 euros per chair and disinfection of touch surfaces 0.60 euros per square meter.

Which areas do you serve for office deep cleaning?
