Office Window Cleaning in Almaty

Optimal Frequency for Office Window Cleaning

The frequency of window cleaning in commercial premises depends on three parameters: floor level, proximity to roads, and the type of glazing. We have broken down four main scenarios to help you estimate a schedule for your business.

Offices on Ground Floors and Near Busy Highways

These windows get dirty the fastest — dust from tires, exhaust fumes, and street particulate matter settle on the glass within 1–2 weeks. In Almaty, the situation is worsened by smog, which lingers in the ground-level air layer for up to 10–15 days without precipitation. In practice, we recommend washing windows on ground floors every 1.5–2 months: within this time, the film becomes noticeable to the naked eye, and raindrops leave streaks that reduce light transmission by 15–20%. If the facade faces Abay, Dostyk, or Ryskulov Avenues, the interval is shortened to 3–4 weeks, especially during the dry season from April to October. Skipping two consecutive cycles leads to the formation of a cement-dust crust, which must be removed with acidic solutions — this is more expensive and harsher on the seals. For rooms with panoramic glazing, we advise monthly cleaning: on large surfaces, every defect is visible from 5 meters away, and clients and partners assess the facade’s tidiness within the first 10 seconds.

Offices on Middle Floors (3–7) and in Green Zones

At a height of over 10 meters, the concentration of street dust is 2–3 times lower, but another factor appears — bird droppings and poplar fluff (May–June). If located away from highways, for example in the Samal-1/2 microdistricts, Gorny Gigant, or Kamenskoye Plato, seasonal cleaning is sufficient — 4 times a year: after winter (March–April), before the summer heat (end of May), after leaf fall (October), and before the New Year holidays. However, if the building has aluminum frames with thermal breaks, they require more frequent maintenance — every 2–2.5 months. The reason is that condensation accumulates at the profile joints, mixes with dust, and clogs the drainage channels; with seasonal cleaning, this problem goes unnoticed until mold appears on the slopes. In our practice, there was a case in a business center on Al-Farabi Avenue where, due to a missed autumn cleaning, four seals had to be replaced — the repair cost more than three annual cleaning cycles.

Business Centers and Offices with Panoramic Glazing

For Class A and B buildings with floor-to-ceiling windows, the frequency is determined less by dirt and more by image standards. Tenants of such premises typically demand an impeccable appearance of the glass — no streaks, runs, or fingerprints after rain. The optimal schedule is every 3–4 weeks in the warm season and every 6–8 weeks in winter. At heights over 15 meters, the exterior side is washed by industrial climbers using telescopic poles and demineralized water — this eliminates the film from hard water typical of Almaty’s water supply (total hardness 5–7 °dH). The interior side only needs wiping once a month with a microfiber cloth and a hypoallergenic solution, such as Kiehl or Sodasan, which do not leave a sticky film. Saving on winter cleaning (skipping 2–3 months) leads to the spring sun highlighting the dirt so brightly that the glass has to be washed twice in a row, spending twice as much time and chemicals.

Specifics for Almaty: Smog, Poplar Fluff, and Rainy Season

There are two peak periods in the city when the window cleaning schedule needs to be tightened. The first is from mid-May to the end of June: poplar fluff clogs ventilation grilles and sticks to wet glass after rain. If windows are not washed at least once every 3 weeks during this season, the fluff compresses into felt, which can only be removed mechanically and leaves scratches on plastic frames. The second peak is from late October to mid-November: prolonged rains (up to 10–12 days in a row) wash dust off roofs and roads but leave a grey film on the glass from micro-particles of asphalt and tire debris. Our technologist Aigerim Kassymova recommends ordering a cleaning immediately after the rainy season ends, before the film embeds into the glass structure — this takes about 5–7 days. For offices with wooden frames (historical buildings in the center, Zeleny Bulvar area, Zheltoksan Street), the interval is reduced to 1–1.5 months at any time of year: wood absorbs moisture, and dirt on the glass accelerates the rotting of seals. Moreover, if the premises have magnesium-aluminum frames, they are less prone to corrosion but require careful removal of deposits — harsh chemicals destroy the anodized coating in 2–3 cycles.

Features of Winter Window Cleaning: What You Need to Know

Winter window cleaning in Almaty differs from summer cleaning not so much in technology as in the physics of the process: in freezing temperatures, water freezes faster than it dries, and the temperature difference between a warm room and cold glass creates condensation that leaves streaks. We have restructured the winter protocol so that the solution has time to wash away dirt before it freezes — and without damaging the seals and frames.

How Winter Window Cleaning Differs from Summer

The profi-clean winter protocol changes three parameters: solution temperature, alcohol concentration, and pass speed. We use water heated to 35–40 °C — it prevents instant icing on the glass and better dissolves winter dirt (de-icing agents, bitumen stains, soot from heating). 10–15% isopropyl alcohol is added to the solution: it lowers the freezing point to –10 °C and speeds up evaporation to prevent an ice crust. In summer, these measures are excessive — in the heat, alcohol evaporates faster than water and leaves streaks. Another difference is the water removal technique: in winter, the squeegee is moved without lifting it from the glass, in one continuous motion, so the moisture doesn’t have time to cool and freeze at the edges. In the summer protocol, short pauses are acceptable. Additionally, we halve the interval between cleaning adjacent panes — no more than 40 seconds, compared to 90–120 in summer. This prevents a situation where the first pane has already frozen while the second is still being washed.

Common Mistakes in DIY Winter Office Window Cleaning

Using hot water above 50 °C. In freezing temperatures of –10 °C and below, hot water creates thermal shock for the double-glazed unit: the inner glass heats up, the outer remains icy — the difference can cause micro-cracks in the spacer bar area. In our practice, there was a case in October: an office on the 5th floor of the Nurly Tau business center poured water at 65 °C on the glass; by morning, two double-glazed units had cracked along the edge. Washing on a sunny frosty day. The sun heats the glass unevenly — the solution dries in patches, leaving streaks of salt deposits from de-icing agents on cold areas. Neglecting seals. Silicone lubricant is applied to rubber seals before washing, not after: if the rubber is wetted first, it freezes to the frame and tears when opened. Using the same bucket for all panes. In winter, the water cools down in 3–4 minutes, and each new pass washes with icy water — efficiency drops by half. We change the water every 2 window sections or every 8–10 minutes depending on the outside temperature. Using household chemicals with ammonia. In freezing temperatures, ammonia crystallizes and leaves a whitish film that can only be removed with a repeat pass — adding an extra 15–20 minutes per floor. Before the winter season, check the composition: if the product contains ammonia, replace it with an alcohol-based concentrate for professional cleaning.

How to Prepare Your Office for Winter Window Cleaning

24 hours before cleaning, we ask that you turn off convectors and radiators near the window row — this reduces the convection of warm air, which drives dust onto the glass and creates a temperature difference. If the radiators cannot be turned off, a thermal insulating layer (cardboard + foil) is placed on the windowsills to prevent cold from the glass from condensing on the inner frame. Remove blinds and heavy curtains — in winter, they accumulate moisture, and after cleaning, damp spots may remain on the fabric, which take 6–8 hours to dry. We recommend scheduling cleaning in the first half of the day when the windows face the shady side: in Almaty in winter, the sun rises in the southeast, and northern facades remain cold until 2:00 PM — these are the optimal hours for cleaning without the risk of icing. Check the seal tightness of the frames — if the seal is worn or there is a gap, warm air from the office meets the cold glass and forms condensation on the inside. In this case, external cleaning will not yield a clean result: condensation will appear within 15–20 minutes. We warn the client and suggest postponing cleaning until the seal is replaced. Arrange access to the external glass — in winter, you cannot open the sashes fully: cold air sharply cools the room, and dew forms on the inner panes of adjacent windows. Our cleaners work through tilt sashes with telescopic poles, and if the windows are fixed, from a lift or with an industrial climber. Access to the external perimeter must be coordinated with the building administration a day in advance to avoid blocking ventilation and fire exits.

How to Prepare Windows for Cleaning: Tips for the Office Manager

Preparation is half the result. An office manager who spends 15 minutes inspecting and clearing the area reduces the actual cleaning time by 30-40% and eliminates complaints to the cleaners about damaged blinds or flooded windowsills. Here’s what you need to check before the team arrives.

Inspection of Frames and Seals: What Breaks Most Often

The first thing we see at profi-clean sites is warped sashes and torn seals on plastic windows. In office structures after 3-5 years of use, the hardware becomes loose due to daily ventilation and vibrations from air conditioners. Before cleaning, check: the sash closes without a gap, the rubber seal has no cracks, the drainage channels in the lower part of the frame are not clogged with construction dust or sand. In Almaty business centers in Medeu and the Samal-3 microdistrict, a common problem is dried-out lubricant in the hinges: in winter, the sash jams, and the cleaner cannot wash the outside without risking breaking the handle. If you notice play, call a hardware technician before washing: cheap repairs now will save you from replacing the double-glazed window tomorrow.

Removing Blinds and Curtains: How Not to Damage the Fabric and Mechanism

Horizontal aluminum blinds in offices are the main dust collectors, but improper removal breaks the slats. We recommend removing all removable elements before window cleaning: blinds, roller shades, tulle. Vertical fabric blinds (slats on plastic clips) need to be carefully removed from the runners — do not pull on the fabric, otherwise the reinforcing tape will tear. In our orders for offices in the “Nurly Tau” business center, there was a case: the office manager simply moved the blinds aside, the cleaner touched them with a scraper during cleaning, and three slats were bent. It is better to move the removed elements to a neighboring room or wrap them in film — moisture and dust from cleaning settle on them. For “day-night” roller blinds (zigzag stripe), be sure to secure the control chain with tape: if it dangles, it can get pulled into the gap when the sash is open.

Protecting Windowsills and Floors: What to Lay Under the Windows

Office windowsills made of artificial stone (Corian, LG Hi-Macs) and laminate do not tolerate standing water. At profi-clean sites, we always lay technical film or thick rags on the windowsill and floor under the window — this is our standard procedure. Advice for the office manager: before our arrival, remove all papers, folders, flower pots, and souvenirs from the windowsill. Even if the cleaner works carefully, splashes of water with cleaning solution can travel up to a meter from the window. It is especially important to clear the area of heating radiators under the windowsill — dust accumulates there, and during cleaning, it mixes with water, leaving dirty streaks on the radiators. In offices with carpeting (typical for Almaty class B business centers), we additionally cover the floor with polyethylene 1.5 meters from the wall — wet carpeting takes two days to dry and starts to smell musty.

Checking the Glass Condition: Chips and Scratches

Before starting the wash, inspect the glass in the light at a 45-degree angle — this reveals micro-cracks from branch or gravel impacts. In Almaty, due to frequent hail (especially in May-June), pinpoint chips appear on office windows that are invisible under normal light. If a cleaner runs a scraper over such a chip, it will worsen the crack — and the double-glazed window will need replacing. At profi-clean, we always photograph defects before work, but the office manager should do the same on their phone: record the date and angle of the crack. This eliminates disputes if the crack worsens after washing due to temperature changes (in winter, at -10°C outside and +24°C in the office, glass expands by fractions of a millimeter). On panoramic windows higher than 2.5 meters (often in meeting rooms), check the sealant at the edges — peeled silicone lets moisture inside the double-glazed unit, and after washing, non-drying condensation appears between the panes.

Access to the exterior: what to check on the facade

Washing exterior windows at height is the responsibility of the cleaner and their insurance, but the office manager must ensure access. 30 minutes before the profi-clean team arrives, remove all air conditioners, awnings, and advertising banners from the facade that block the opening — if possible without hiring a contractor. In offices on upper floors (12th and above in the “Almaty Towers” business center), check if the sashes open in “winter ventilation” mode — on the micro-lift of the hardware. If the sash sticks, the cleaner won’t be able to wash the exterior side with a telescopic pole — climbing equipment will be needed, increasing work time by 40-50%. We encountered this situation at the “Dostyk Plaza” business center: the sash jammed due to frame distortion after building settlement, and the exterior glass had to be washed from a lift — taking half a day instead of two hours. A timely detected fault saves budget and nerves. “`

Comparison of manual and professional window washing

When an office manager decides who will wash the windows — a regular cleaner or a cleaning company — the choice often comes down to perceived savings. But the difference between amateur washing and professional work goes much deeper than just the price.

Difference in quality: micro-streaks and film

With manual washing using a standard cloth and supermarket cleaner, a micro-film remains on the glass — invisible to the eye but noticeable on a sunny day. This is a deposit of hardness salts from Almaty’s tap water (city water is 8-10 °dH), which is not removed by regular chemicals. The professional profi-clean approach uses demineralized water with TDS meter control and special Kiehl concentrates that bind salts and prevent them from settling. In practice, this means that after our washing, the glass remains transparent even in the sun, while after manual washing, a whitish film appears within a week, especially on south-facing windows. If the office has panoramic glazing, this difference becomes critical — streaks in the sun are visible from 10 meters.

Tools and safety for frames and profiles

Soft microfiber cloths and rubber squeegees for a professional are consumables replaced after every 5-10 windows. With manual washing, the same cloth is used on all windows, and abrasive particles from the windowsill scratch the PVC profile. This is invisible on white frames, but on colored or laminated ones (wood imitation), micro-scratches remain that yellow over time. At profi-clean, a clean set is used for each window: a separate cloth for the frame, a separate one for the glass, and a separate one for the sill. Additionally, for aluminum profiles (often found in Almaty business centers), a neutral pH composition is used that does not oxidize the metal — regular alkaline glass cleaner corrodes the anodized coating after 3-4 washes.

Speed and office downtime

Manual washing of one standard window (1.5×1.8 m) takes 15-20 minutes: remove dirt, rinse, dry, eliminate streaks. For 20 windows, that’s 5-7 hours of work for one person. During this time, employees cannot work near the window, light falls unevenly, and wet furniture and carpets create a slip risk. A professional profi-clean team of two cleaners washes the same amount in 2-2.5 hours: one washes, the other immediately squeegees the water. Office downtime is reduced by 2-3 times, which for a 100 m² business center rental is cheaper than it seems at first glance.

Chemicals and allergies in an enclosed space

Household window cleaners (Mr. Muscle, Clin, and similar) contain isopropyl alcohol and ammonia — they evaporate into the air and create a sharp odor that lingers for 2-4 hours. In an office with poor ventilation or recirculation (standard split systems), vapor concentration can exceed the maximum permissible concentration for ammonia (20 mg/m³) in the first 30 minutes after cleaning. profi-clean uses hypoallergenic water-based chemicals Sodasan and Kiehl without ammonia — they are odorless and safe for asthmatics and allergy sufferers. Moreover, during manual cleaning, the product is often sprayed directly onto the glass, and excess drips onto the windowsill and frame, leaving a sticky residue that attracts dust. Professionals apply the chemical to a cloth in a measured way, without waste.

High-rise and hard-to-reach windows

In offices on the 4th floor and above, external window cleaning with standard squeegees on telescopic handles (up to 3 m long) is impossible — you can’t reach the top of the sash from the outside. The regular cleaner either washes only the inside or takes risks by leaning out of the window. For such tasks, profi-clean uses telescopic poles up to 8 m with a swivel adapter and a water-fed system (supplying demineralized water via a hose) — this allows cleaning external glass from the ground or a balcony without safety harnesses and without the risk of falling. In Almaty, high-rise business centers (“Nurly Tau”, “Atakent”) with panoramic glazing are standard, and manual cleaning is simply not applicable for the exterior side.

Drying and final inspection

After manual cleaning, water droplets remain on the glass and dry into spots — these are not streaks but mineral deposits. Professionals wipe the glass dry with a squeegee and rubber blade, finishing with a polish using a dry microfiber cloth. At profi-clean, each window is additionally checked with a flashlight at a 45° angle — this reveals even single lint fibers from the cloth. For standard-sized office windows, this takes 30-40 seconds per window but eliminates complaints the next day. With manual cleaning, such inspection is impossible — you can’t see micro-defects in the sunlight.

Common mistakes when washing office windows

Even with regular office window cleaning, the result is often spoiled by typical miscalculations — from choosing the wrong equipment to ignoring Almaty’s tap water. Here’s what we see most often in our practice.

Mistake 1: Washing windows with household chemicals

Using kitchen or bathroom cleaners is the main cause of streaks and damage to seals. Office double-glazed windows have rubber gaskets that “Fairy” and “Mr. Proper” corrode in 3-4 washes: the rubber hardens, loses elasticity, and stops retaining heat in winter. We use professional hypoallergenic chemicals Kiehl and Sodasan — their pH-neutral composition does not harm the profile and leaves no rainbow spots even in sunlight. On sliding aluminum structures, common in Almaty business centers (“Nurly Tau”, “Almaty Towers”), household chemicals are especially dangerous: they react with the anodized coating, leaving permanent white spots on the frame surface. Before ordering office window cleaning, check with the contractor about the solution composition — if they name a universal product from a supermarket, that’s a reason to decline.

Mistake 2: Ignoring water hardness in Almaty

Tap water in Almaty has high hardness — up to 7-8 mg-eq/L compared to the standard 1.5-2. This means that after drying, a dense white coating of calcium and magnesium salts remains on the glass. Office managers often complain: “we wash every week, but the windows are still cloudy.” The problem isn’t frequency, but that the water isn’t filtered before cleaning. At profi-clean, all our services use a reverse osmosis system: demineralized water leaves no salts, and the glass stays clear until the next rain. On the panoramic windows of the “Esentai Tower” business center, the difference is immediately visible — after our cleaning, reflections are even, without a white haze. If the contractor skimps on filtration and washes with regular tap water, after 3-4 procedures the deposit etches into the glass and can only be removed with acid polishing. When ordering professional office window cleaning, request a clause in the contract about using demineralized water — this will prevent deposits for years to come.

Mistake 3: Cleaning without considering the type of dirt

Office windows rarely have uniform dirt — soot from highways, bird droppings, remnants of construction dust after renovations, and an oily film from running printers. Trying to clean everything with the same product leads to streaks. Soot from Abay Avenue requires an alkaline solution to break down the soot; bird droppings need an acidic one, otherwise a matte stain remains visible against the light; construction dust can only be removed with generous wetting, otherwise it scratches the glass. We had a case in a building on Zharokova Street: windows hadn’t been cleaned for a year, and the dirt layer had hardened into a crust. A standard scraper couldn’t handle it — we had to apply a professional gel remover for 15 minutes and remove it layer by layer. If an office manager can’t distinguish between types of dirt, it’s better to entrust the diagnosis to a cleaning technologist — they will select the right solution for each specific stain and reduce work time by 30–40%.

Mistake 4: Incorrect technique with the scraper and rubber squeegee

Even with good chemicals, you can get streaks if you don’t maintain the correct tool angle. The scraper for removing dried stains is held at a 30–35 degree angle — if pressed harder, the steel blade leaves micro-scratches that become noticeable in sunlight over time. The rubber squeegee (water blade) is moved strictly horizontally or vertically, without interruption, and the blade is wiped dry after each pass — a drop of old water on the squeegee leaves a streak on clean glass. In offices on the upper floors of the “Almaty Towers,” wind increases evaporation, and if the squeegee is moved slowly, the water dries before the blade reaches the edge, leaving a “step” of mineral salts. Our cleaners undergo training: on a 2×2 meter pane of glass, the norm is no more than three squeegee interruptions across the entire surface. When ordering office window cleaning services, ask the technician to show you their working tools — a chipped rubber blade or a rusty scraper guarantees defects.

Mistake 5: Skimping on safety when cleaning at height

In offices with panoramic glazing (floor-to-ceiling windows, internal atriums), employees sometimes try to clean windows from the windowsill or a step ladder. This is not only dangerous — a fall from a height of 2–3 meters can cause serious injuries — but also ineffective: from a ladder, you can’t reach the top part of the sash, leaving a dirty strip. According to Kazakhstani regulations, window cleaning at heights over 1.8 meters requires an industrial climber with insurance and a work permit. At profi-clean, cleaners with industrial climbing certifications are dispatched to high-rise sites, using Petzl safety harness systems and a mandatory second anchor point. In the “Almaty Towers” business center, the atrium height is 12 meters, and working there without climbing equipment is prohibited. If an office manager decides to save money and allows a cleaner to work on the windows without safety gear, they risk not only the person’s life but also the company’s administrative liability for violating occupational safety regulations. Ordering office window cleaning with high-altitude work should only be done from licensed cleaners — a cheap option without insurance will cost more at the first inspection.
