Window Cleaning Berlin - Streak-Free from Frame to Glass Edge
Professional window and frame cleaning to professional standards. Immo-Clean GmbH applies DIN EN 13549-aligned methods for glass surfaces, frames, and sills. Tariff-bound permanent staff with professional cleaning technology - streak-free results for offices, commercial buildings, and residential properties.
Window Cleaning: On site across the city
Own teams look after glass, frames, and facade panes throughout the 12 Berlin districts, and each visit lands documented and verified in the site manager's file.

Window Cleaning: Streak-free results for glass, frames & sills
The Window Cleaning Berlin service from Immo-Clean GmbH covers all glass surfaces of a property - from office windows and shopfronts to glass facades, partitions, and conservatories. Fixed cleaning teams, documented quality loops, and an on-site site manager ensure that property managers and commercial tenants receive consistently verifiable streak-free results.
Intervals across a building portfolio
Portfolios receive one glazing plan per building, tuned to facade orientation, sunlight hours, and where the access points sit. Tower in Mitte, estate block in Spandau, or Marzahn walk-up - the documented standard stays identical, and a single monthly report consolidates the results. Request a portfolio quote.
Standards and methods
Three reference frames shape every glazing brief: DIN EN 13549 quality levels, DGUV-safe rope and platform work, and treatment matched to the glass in question - coated, tempered, or laminated. Osmosis and pure-water results feed documented quality loops that owners and property managers can inspect on request.
A dedicated site manager on site
One named site manager owns your glazing plan - pane inventory, exposure side, access method, and interval per facade. They brief the crews, verify the streak-free finish against the light on quality rounds, and reach commercial buildings in Berlin inside 24 hours. Current glazing contracts stretch from tower blocks in Berlin-Mitte and Charlottenburg out to housing portfolios in Pankow, Spandau, and Köpenick; every location we serve is listed on the Berlin service areas page.
Quality you can file
Every visit closes with a pane-by-pane record: floors cleaned, method used (pole, ladder, or pure-water), and defects such as seals, scratches, or condensation noted for the owner. The monthly overview consolidates all buildings, and streaks are caught on the next light-check round - not by the first complainant. Alongside glazing we deliver office cleaning in Berlin, routine stairwell cleaning in Berlin, and contract maintenance cleaning in Berlin under one roof.
Window Cleaning in All Berlin Districts & Brandenburg
Building glazing is planned per exposure: weather-facing facades soil faster and run on shorter cycles, sheltered courtyards on longer ones - and every facade's access method (pole, ladder, lift, or rope) is fixed in the plan before the first visit. We clean on this basis across Berlin-Mitte, Charlottenburg, Friedrichshain, Kreuzberg, Spandau, Köpenick, Pankow, Neukölln, Wilmersdorf, Schöneberg, Tempelhof, and Steglitz - all districts on the Berlin service areas page.
Berlin-Mitte & Eastern Districts
Berlin-Mitte assignments centre on the government quarter; around the East Side Gallery in Friedrichshain we clean shopfront glazing before opening; near the Tierpark in Lichtenberg and across the large estates of Hellersdorf and Marzahn we run residential pane schedules.
Kreuzberg, Neukölln & Northern Districts
Window cleaning in Kreuzberg is scheduled around SO36 and the Bergmannkiez, while window cleaning in Neukölln is organised around Hermannplatz and Sonnenallee. In Pankow and Reinickendorf, period buildings with tall staircase windows are cleaned with telescopic poles - no scaffolding in the stairwell.
Charlottenburg-Wilmersdorf & City West
City West means height and heritage: office towers off Charlottenburg's Kurfürstendamm with rope-access facades, Wilhelminian-era windows around Wilmersdorf's Olivaer Platz, and protected glazing in Schöneberg's Bavarian Quarter.
South, West & Brandenburg
Glazing across southern Berlin in Tempelhof, Steglitz, Zehlendorf, Lichterfelde, and Treptow is dominated by villa conservatories and skyline glass; in the west Spandau adds industrial glazing, in the south-east Köpenick and Adlershof research-campus facades. Portfolio rounds also reach Potsdam and the whole state of Brandenburg.
Mitte: Glazing under heavy traffic and shopfronts in the centre - we clean windows and glass facades at height with safe access methods.
Friedrichshain-Kreuzberg: Period buildings and lofts with tall windows - we clean with telescopic poles, no scaffolding required.
Pankow: Residential buildings with stairwell and apartment windows - here we clean on flexible schedules for tenants.
Charlottenburg-Wilmersdorf: City West shopfronts and offices - we clean display windows and glass fronts streak-free.

Case Study: Office Tower in Charlottenburg
A representative example of how we take over and manage window cleaning for a high-traffic commercial property in Berlin. The concrete figures vary depending on the property.
Starting situation: An office tower in Charlottenburg with 8 floors and approximately 350 m² of glass surface. The previous cleaner used standard tools on every surface, ignored sun exposure patterns, and had no documentation. Tenant complaints about streaks increased month over month.
Assessment and plan: We reassessed all glass surfaces by type: coated office windows (floors 1-4), tempered entrance canopy, laminated stairwell panes. Surface-specific tool assignment with pure-water final rinse. Scheduling was shifted to early morning before direct sun hit critical east-facing facades.
Implementation with a fixed team: A fixed glazing crew took over floor by floor, led by the site manager and their pane inventory. All work was scheduled outside core hours, so tenants saw clean windows in the morning and no cleaning traffic during the day.
What changed for the property
- Complaints about streaking dropped sharply
- 350 m² of glass reliably maintained across 8 floors
- Cleanliness score reached 4.7 out of 5
- Sun-position-based scheduling for east-facing facades
- Pure-water final rinse on visibility-critical panes
The case above is an illustration of method only - not an offer, and no reference to a single identifiable property.
What Determines the Price? A Worked Example
What window cleaning costs is decided by the storey, the glazing type, and the frame material - a ground-floor uPVC window is a different job from a seventh-floor coated pane over a conservation facade. The final figure is fixed after the free site survey.
What factors into the quote
- Glass area and type - the surface total, pane count, and blend of standard, coated, tempered, and laminated glazing set tools and minutes; tall facades add rope or platform access
- Frequency - a one-off deep clean or monthly and quarterly visits; shorter cycles beat rare heavy cleans on both price and look
- Access and height - ground-floor shopfronts, water-fed poles, scaffolding, or rope teams each set a different cost basis
- Billing model - fixed cycle prices per facade side include access planning and quality control; lift or rope deployment is quoted per deployment day
Fixed price after the survey
Window cleaning is quoted per pane inventory and result - for example "north and east facades cleaned streak-free, frames and sills included, defects documented" - because three variables dominate the effort: the floor (each storey above pole reach adds access cost), the glazing type (coated, tempered, or laminated panes need their own blades and products), and the frame material (wood takes longer per pane than aluminium or uPVC). Materials, access planning, and quality control are inside the cycle price; one fixed figure is set after the free site survey. Pricing overview.

Window Cleaning for Every Berlin Property Use
Different buildings need different cleaning rhythms. We match intervals, methods, and access to the use of each property.
Office Building
We coordinate floors, reception areas, and interior partitions with fixed teams. Visits are timed outside core working hours, often early morning, to avoid streak marks from midday sun.
Shopfront & Retail
Display windows, entrance glass, and partitions receive a clear schedule that keeps the frontage spotless for opening hours and stays out of customer flow.
Residential Complex
Stairwell, communal, and apartment windows are cleaned with a zone plan that keeps residents informed and minimizes access interruptions.
Hotel & Hospitality
Hotel glass in lobbies, conference zones, corridors, and back of house is slotted around guest rhythms, keeping operations calm.
Medical Practice
Surgery glazing follows the hygiene plan: waiting-room panes, treatment-room glass, and sanitary windows, handled by briefed staff.
Administration
One site manager bundles glazing, stairwell, and care dates for an authority building; monthly summaries plus quality walks keep the trail auditable.
Daycare & School
Classroom, corridor, and sanitary glazing is cleaned outside opening hours; touchpoints and holiday deep cleans are planned as separate line items.
Glass Facade
Multi-storey glass facades receive rope access or platform lift cleaning. Pure-water final rinses leave a streak-free result even on coated glass.
Industrial Facility
Glazing beside production lines and in office wings follows the plant's safety and shift calendar; stubborn films come off with matched agents.
Conservatory & Skylight
Conservatory and skylight glass is cleaned inside and out, often with water-fed pole systems. Frames and seals are included to prevent long-term damage.
Cleaners and Methods for Window Surfaces
The right method for building glazing depends on height, exposure, and glass type - chosen pane by pane, never by habit.
Interval & Exposure Logic
Weather sides and street-facing facades collect dust, pollen, and traffic film fastest, so they run on four- to eight-week cycles; sheltered courtyard glazing holds twelve weeks or more. The interval is set per facade side, not per building.
Access per Storey
Ground floors are cleaned classically with squeegee and blade; upper storeys by water-fed pole up to the reach limit; facades beyond that by lift or rope access. Whichever route is used, the streak-free criterion is identical: checked against the light before handover.
Pure-Water Technology
For facades and partitions the final rinse runs through deionised cartridges, so panes dry without mineral spots - no wiping contact, no ladders against glass, and no detergent film that re-soils faster.
Frame & Seal Handling
Aluminium, wood, and uPVC frames are wiped with material-matched agents, drain grooves are cleared, and seal edges are kept free of cleaner residue - the details that decide whether a window reads as clean months later.
Interval Models by Exposure and Storey
Weather sides set the pace: a west facade facing open street takes rain film and dust noticeably faster than a sheltered courtyard side, so we split intervals within one building instead of averaging them. Height matters as much - panes above pole reach collect less street grime but cost more to visit, which argues for longer cycles finished with pure water. Interior conditions count too: glazing next to a staff kitchen greases up sooner than meeting-room windows on the same floor. The result is a per-side matrix that prices the whole envelope honestly.
Frame Material Shifts the Rhythm
Timber frames swell and shed paint when washed too hard, so they receive gentler agents and longer gaps between wet cleans. Aluminium tolerates frequent wiping and rewards short cycles on pollen-facing sides. uPVC sits between the two and develops a grey film when neglected too long. Seals age faster than the glass they hold: once a gasket hardens, it draws a dark edge line onto the pane that no squeegee removes. Frame material therefore changes the agent, the interval, and the care plan - not just the line on the quote.
Window Cleaning in Eight Clear Steps
From the pane inventory to the light-check handover, every glazing assignment follows the same eight documented stages.
- First walk-through: building dimensions, glass types, facades, access points, and constraints like coated or heritage glazing go on record.
- Every pane, frame, and sill then carries its interval, access method, and target result - one standard from basement to roof.
- Facade zones are mapped by the site manager, who sequences routes, entry points, and working windows.
- The assigned crew is walked through the building: key rules, DGUV access plan, and which panes take which method.
- Poles, pure-water packs, and - for high facades - platform or rope kits are staged per building section.
- Each visit works down the pane inventory; finished surfaces and defects (seals, cracks, condensation) are logged as it goes.
- Deep cleans for frames, sills, and facade glass get their own slots inside the annual plan.
- Quality walks, per-visit records, and the monthly summary keep owners and operators continuously in the picture.
