Window & glass cleaning in Hamburg — streak-free with purified water. Non-binding fixed-price quote within 24 hours.

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. Because ultra-pure water dissolves dirt by purely physical means, we use no chemical surfactants, alcohols, or fragrances at all. No wastewater contaminated with cleaning chemicals ends up in the soil or the sewer system. Plus, there are no harsh chemicals to attack your seals and window frames.
