Ventilation Cleaning in Tallinn and Harju County — Professional Duct and System Maintenance

Ventilation cleaning (duct cleaning, ventilation system maintenance) is a set of technical measures aimed at removing dust, grease, mould, pollen, bacteria and other deposits from supply and extract ducts, fans, heat recovery units, filters and terminal devices — deposits that over time restrict airflow and harm indoor air quality. The job covers both cleaning visible components (grilles, diffusers, filter cassettes) and mechanically and pneumatically clearing the inside of the ductwork along its full length — right up to the roof outlet.

Estonia's indoor air quality standards (EVS-EN 16798) and fire safety requirements for catering premises (the Rescue Board's guidance on grease duct cleaning) require ventilation systems to be kept clean and maintained. A properly cleaned system uses less electricity, distributes air more evenly, prevents the spread of mould and allergens, and extends the life of the whole system by 30–40% on average. Ventilation cleaning isn't a cosmetic service — it's a direct investment in the health of residents and staff, the building's energy efficiency and the preservation of its value.

Toru SOS OÜ carries out one-off cleaning as well as long-term maintenance under contract, across Tallinn and Harju County. We document every job — taking before/after photos, measuring airflow speed and duct pressure drop, and issuing a cleaning report suitable for submission to the Rescue Board, an insurer or your apartment association's general meeting.

Recommended cleaning intervals depend on the type of property, the load on the ventilation system and how the rooms are used. The general rules Toru SOS OÜ follows in Tallinn and Harju County match both Estonian practice and the European standard EN 15780:

• Mechanical ventilation in houses and flats — every 5–10 years
• Shared extract shafts in apartment blocks — every 5 years
• Offices and commercial buildings — every 2–5 years depending on load
• Kindergartens, schools and healthcare facilities — every 1–2 years (mandatory)
• Restaurant and café kitchen grease ducts — at least 1–2 times a year
• Fast-food and large kitchen grease ducts — every 3–6 months
• Industrial buildings (dust, chemicals, painting) — on an individual schedule, typically once a year
• After renovation or a fire — immediately before restarting the system

Ventilation problems often go unnoticed until they start to affect your living or working environment directly. If you notice at least one of the signs below, it's time to have your ventilation system inspected and cleaned. The earlier a problem is spotted, the cheaper and easier it is to fix.

• The air feels stuffy, heavy or 'stale' even with a window open
• Kitchen or bathroom smells don't disappear and spread to other rooms
• Mould keeps appearing near the bathroom ceiling and sealant lines
• Condensation forms around window and door frames, glass 'fogs up'
• Dust settles on grilles and diffusers just days after cleaning
• The extract fan has become noticeably noisier
• A sheet of paper won't stay on the extract grille — no air is flowing through
• Allergy and asthma symptoms get worse at home
• A visible layer of grease builds up under a restaurant kitchen hood
• Smoking or cooking smells 'linger' in the walls and textiles
• Heating bills have risen even though usage habits haven't changed

Toru SOS OÜ cleans every type of ventilation system in Tallinn and Harju County — from a single flat's extract duct to the complex systems of large apartment blocks and industrial sites. We work with both natural draught and mechanical ventilation (supply + extract, heat-recovery units).

• Flat supply and extract ventilation (kitchen, bathroom, WC)
• Shared vertical extract shafts in apartment blocks, on every floor
• Heat-recovery units (Vallox, Ensto, Komfovent, Systemair and others)
• VAV/CAV systems and main ducts in office and commercial buildings
• Kitchen grease filters, hoods, grease ducts and roof outlets
• Wet areas and pool equipment in hotels and spas
• Kindergarten and school ventilation units
• Dust, exhaust and welding-fume systems in industrial buildings
• Flues and chimney connections for solid-fuel appliances (fireplace, stove, boiler)
• Chemical flushing of heat exchangers (plate and tube type)
• Diffusers, grilles, ventilation dampers and roof outlets

Toru SOS OÜ always cleans ventilation to the same tried-and-tested protocol. This approach ensures that no section of duct is missed, no dirt escapes into the rooms, and you receive full documentation of the work carried out.

• 1. Site visit and consultation — a technician comes out, assesses the system type, measures airflow and prepares a free quote
• 2. Video diagnostics — we use an endoscope camera to check the inside of the ducts and show you real footage of the level of contamination
• 3. Work area preparation — furniture and floors are covered, a negative-pressure dust containment unit is set up so debris doesn't spread into the room
• 4. Removal of grilles, diffusers and filters — cleaned on site or replaced with new ones
• 5. Mechanical cleaning — rotating brushes, cutters and pneumatic whips remove deposits built up on the duct walls
• 6. Pneumatic blow-down — compressed air (up to 8 bar) drives loosened dirt towards the extract unit, where it's captured by a HEPA-filtered industrial vacuum
• 7. Chemical disinfection — treatment with food-industry-approved agents against bacteria, mould and viruses (where needed)
• 8. Grease duct cleaning — for restaurant kitchens, hot-water high-pressure and chemical cleaning up to the roof outlet
• 9. System restoration and airflow balancing — all components refitted and checked
• 10. Final inspection and documentation — before/after photos, measurement results, cleaning certificate and warranty document

Quality ventilation cleaning is impossible without professional equipment. Toru SOS OÜ continually invests in equipment from leading European manufacturers (Lifa Air, Kair, Nilfisk, Karcher Professional, Rothenberger), certified for ventilation duct cleaning and compliant with Estonian fire safety and occupational health requirements.

• Rotating cleaning robots (Lifa Air) with flexible shafts reaching up to 30 m
• Pneumatic whips and brush sets in a range of diameters (Ø50–800 mm)
• HEPA-filtered (H13) industrial vacuums that don't release fine dust back into the room
• Negative-pressure generators with 2,000–6,000 m³/h capacity
• Compressed-air units up to 8 bar with dedicated grease duct cleaning nozzles
• Wi-Fi endoscope cameras for internal system inspection
• Hot-water high-pressure washer (up to 150 bar, 80°C) for kitchen grease ducts
• Anemometers and differential pressure gauges for measuring airflow and pressure drop
• ATP bacteria meters for checking microbiological cleanliness of indoor air
• Food-industry-approved disinfection agents

Ventilation cleaning is closely linked to other building services. During cleaning we often find that the heating system also needs flushing, a heat exchanger is scaled up, or an odour from the drainage is spreading through the ventilation to other flats.

Everything starts with your call or online enquiry. Our dispatcher listens to the problem, assesses how urgent it is, and sends the nearest available technician. In an emergency we head out immediately; for planned work we agree a time that suits you. The technician arrives with the equipment and spare parts needed to sort things out in a single visit wherever possible.

On site we run a first diagnosis, pin down the exact cause of the fault and propose the best solution. We agree the scope and price with you before starting, so you know exactly what you're paying for. Any extra materials or work are always confirmed separately before we proceed.

Once the job is finished we test the system, clean up after ourselves and issue a report. We give you practical advice on further care and, where useful, can offer a maintenance contract with regular preventive check-ups.
