Window Cleaning Berlin - 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
For several properties, we create an object-specific window cleaning plan that takes facade orientation, sun exposure, and access points into account. Property managers receive one central contact and consistent documentation, regardless of whether a property is in Mitte, Spandau, or Marzahn. This keeps quality and traceability consistent across every location. Request a portfolio quote.
Standards and methods
DIN EN 13549-aligned quality benchmarks, DGUV-compliant occupational safety for rope and platform access, and material-appropriate treatment for coated, tempered, and laminated glass guide our work. For pure-water and osmosis systems, we document results in our quality loops and make them transparent to owners and property managers on request.
A dedicated site manager on site
We appoint a dedicated site manager from our team for every property. This person is the first contact for the property manager and tenants, carries out weekly quality rounds, and coordinates the cleaning team. For high-rise or commercial buildings in Berlin, the site manager is usually on site within 24 hours. Regionally, we serve properties in every Berlin district - from Berlin-Mitte through Charlottenburg and Pankow to Spandau and Köpenick. A complete overview is available on our Berlin service areas page.
Documented quality
We use checklist-based quality loops: after every visit, each team documents cleaning points, material use, and anything unusual. Property managers can receive a consolidated monthly quality overview on request. Streak complaints are not only corrected after a complaint; they are identified during routine quality rounds. Our office cleaning in Berlin, stairwell cleaning in Berlin, and maintenance cleaning in Berlin complement the service portfolio.

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 coordinated team took over the property with a clear zone plan, documented quality checks, and a site manager as the direct contact. Visits were aligned with opening hours so cleaning could continue without disrupting operations.
What changed for the property
- Streak complaints reduced significantly
- 350 m² of glass reliably maintained across 8 floors
- Cleanliness rating of 4.7/5 stars
- Sun-position-based scheduling for east-facing facades
- Pure-water final rinse on visibility-critical panes
This case study illustrates our approach and does not constitute an offer or refer to a specific named customer property.
What Determines the Price? An Illustrative Calculation
Window cleaning is not charged as a flat rate per square metre; glass area, accessibility, frequency, and contamination level all matter. The following values are non-binding guidance figures - the binding fixed price always follows the free site survey.
What factors into the quote
- Glass area and surface type - total surface, number of panes, and the mix of standard, coated, tempered, and laminated glass determine the time and tools required; higher facades need rope or platform access
- Cleaning frequency - one-off deep cleaning, monthly, or quarterly visits; regular intervals are more efficient than infrequent intensive cleans
- Access and height - ground-floor shopfronts, water-fed poles, scaffold, or rope access all change the cost basis
- Contract model - long-term contracts with fixed intervals include materials, quality control, and site management
Fixed price after the survey
An hourly rate pays for attendance, not the result - a fixed-price package pays for a defined result agreed in advance, so efficiency benefits us rather than increasing your bill. Every service is listed separately in the quote, and additional services such as facade cleaning, deep cleaning, or specialist cleaning are clearly separated and never added silently. Materials, quality control, and site management are included; the binding fixed price is issued only 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
Lobbies, conference areas, corridors, and back-of-house glass are coordinated according to guest volumes so operations remain undisturbed.
Medical Practice
Waiting rooms, treatment-area glass, and sanitary windows are cleaned according to the hygiene plan by trained staff.
Administration
Several parts of a building are coordinated through one site manager. Monthly reports and quality rounds make the service traceable.
Daycare & School
Classrooms, corridors, and sanitary windows are cleaned during closing hours. Contact surfaces and holiday deep cleans are planned separately.
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
Office wings and production-adjacent glazing are cleaned in line with safety and shift plans. Heavy soiling is removed with material-appropriate methods.
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
Choosing the right method protects glass, frames, and seals. Before use, we check the surface, the soil, and material compatibility.
Material-Appropriate Cleaners
pH-neutral maintenance cleaners cover everyday needs. Specialist products are used only where the surface and the type of soil require them - for example, anti-etch treatments on coated glass.
Glass Type Selection
Coated, tempered, laminated, and frosted glass each receive their own squeegee, blade, and product. Slip resistance, optical clarity, and preservation of value come first.
Pure-Water Systems
For windows, glass façades, and partitions we use demineralized or osmosis water for the final rinse, depending on height and access. This eliminates mineral residue and streak marks.
Frame & Sill Care
Frames and sills are treated according to their material - aluminium, wood, or uPVC - to prevent corrosion, swelling, or discolouration over time.
Window Cleaning in Eight Clear Steps
From the initial survey to documentation, responsibilities, intervals, and quality targets remain transparent.
- Initial survey: we record building size, glass types, facades, access points, and special requirements such as coated or heritage glass.
- Every glass surface, frame, and sill is recorded with its frequency, method, and defined result in a clear service specification.
- The site manager divides the facades into understandable zones and plans routes, access points, and time windows.
- A fixed team is briefed on house rules, DGUV safety requirements, keys, and sensitive zones before the first deployment.
- Squeegees, blades, pure-water systems, ropes, and platforms are matched to the surfaces and property size and made ready for use.
- Routine cleaning follows the agreed schedule, with completed surfaces and any unusual findings documented.
- Periodic intensive cleaning for frames, sills, or facades is scheduled separately and integrated into the annual plan.
- Quality rounds, visit records, and monthly reports give property managers and operators a reliable overview at all times.
