Service · Commercial window & glass cleaning
Ruiz Büroreinigung Hamburg keeps windows and glass crystal clear in offices, law firms, and commercial buildings — with more than 20 permanently employed specialists, a modern purified-water system that uses reverse osmosis, and no subcontractors. Working from the ground, we clean streak-free at heights of up to 18 meters, gently and with no cleaning chemicals — on a flexible quarterly schedule or as a one-time job.
The service
Window and glass cleaning at Ruiz combines a craftsman’s precision with state-of-the-art purified-water technology — for spotless, streak-free glass throughout your offices and business premises. We clean windows inside and out, including frames, grooves, and windowsills, plus glass partitions and exterior facades.
Our eco-friendly purified-water method (reverse osmosis) completely demineralizes ordinary tap water. The resulting ultra-pure water lifts dirt by purely physical means, with no chemicals, and dries without residue. With no sticky surfactant film left behind, your glass stays clean noticeably longer. Our clients include law firms, tax advisory firms, IT companies, and agencies in the city center, in HafenCity, and all across Hamburg.
Whether you add it to your janitorial services on a regular schedule (e.g., quarterly) or book it as a one-time job, you get a dedicated team, direct lines of communication, and personal service. To learn who’s behind Ruiz, visit our About us page.
Service catalog
We keep the view clear at every level — from individual office windows to entire glass structures.
Technology & environment
Purified water is ordinary tap water that has been fully demineralized by reverse osmosis and mixed-bed resin. It binds dirt by purely physical means and dries without leaving any residue.
Glass types & buildings
From a landmark-protected historic office building (Kontorhaus) to a modern glass facade in HafenCity — we have the right equipment for the job.
Classic window types in older buildings and new construction. Both sides of the glass cleaned thoroughly, including frames, grooves, and hinges.
Presentable interior glass in law firms and IT offices. Cleaned streak-free with microfiber cloths — no chemical smells during business hours.
Exterior facades of modern office buildings up to 18 m high. Cleaned with ease using carbon poles and purified water — no street closure needed.
First impressions count: entrance doors, automatic doors, and vestibules cleaned of fingerprints, splash marks, and street grime.
We thoroughly remove moss, algae, and bird droppings from sloped glass, using telescopic equipment and gentle water pressure.
Once they’re clean, dome skylights and roof windows in offices and commercial halls bring full daylight back to the workplace.
Pricing & calculation
We charge a transparent fixed price for window and glass cleaning. Because glass area, window types (e.g., standard windows, muntined windows, coupled windows), accessibility, and working height vary widely from building to building, we determine the cost during a short, free site visit.
Our fixed price covers everything: professional reverse-osmosis units, carbon telescopic poles reaching up to 18 meters, Unger hand tools, travel, protective clothing, and pay above the collectively agreed wage (Tariflohn) for our permanently employed cleaners.
You’ll receive your detailed, non-binding quote within 24 hours — as a flexible fixed price for regular visits (cancel monthly) or as a one-time job with no contract commitment whatsoever.

With the purified-water method, ordinary tap water is demineralized on site using reverse osmosis and mixed-bed resin filters. This ultra-pure water is highly effective at dissolving dirt and binds soot, dust, and pollen without chemical cleaning agents. Because no minerals or surfactants remain in the water, the glass air-dries completely free of streaks and spots.
The cost depends on the number of windows, the glass area, the window type (e.g., tilt-and-turn, box windows, fixed glazing), and accessibility. Because every building is different, we start with a short, free site visit and send you a transparent, non-binding fixed-price quote within 24 hours — with no hidden costs.
Yes. At Ruiz, professional window cleaning always includes the frames, rubber seals, and both interior and exterior windowsills. During the site visit, we agree on the exact, binding scope of work with you.
With our water-fed Unger carbon telescopic poles, we clean facades and windows up to approx. 18 meters high (roughly 5 to 6 stories) safely, from stable footing on the ground. That saves you the expense of scaffolding or boom lifts and protects walkways and landscaping.
In busy urban locations (e.g., downtown Hamburg, HafenCity, Altona), we recommend cleaning every 2 to 3 months. In quieter locations, cleaning twice a year (spring and fall) is usually enough. Interior glass partitions are often handled monthly as part of routine janitorial cleaning.
No. We work quickly, quietly, and flexibly. On request, we start as early as 6 a.m., before your workday begins, or come on a Saturday. Exterior cleaning with the reverse-osmosis method happens entirely outside the building and doesn’t disturb anyone in the office.
No. You can book window cleaning on a regular schedule (e.g., quarterly, cancel monthly) or as a one-time job with no contract commitment whatsoever. We earn your business with quality, month after month.
We use only our own permanently employed cleaners from Ruiz Büroreinigung Hamburg — 0% of our work goes to subcontractors. Our team is paid above the collectively agreed wage, permanently employed, covered by liability insurance, and trained in the safety regulations of BG BAU (the statutory accident insurance institution for the construction and cleaning trades).
Yes — most of our clients prefer it that way. Your routine janitorial cleaning and periodic window cleaning run under one contract, with one point of contact. No double coordination — one provider for everything.
Yes, 100%. Because ultra-pure water dissolves dirt by purely physical means, we use no chemical surfactants, alcohols, or fragrances at all. No harmful wastewater ends up in the soil or the sewer system. Plus, there are no harsh chemicals to attack your seals and window frames.
