Window cleaning cost in Luxembourg 2026

Here are the average prices observed in Luxembourg for window cleaning in 2026:

All prices exclude VAT. Window washing in a private home is taxed at the reduced 8% rate; window cleaning for offices, shops and other business premises at the standard 17%. Luxembourg's high labour costs push window cleaning rates 20–30% above neighbouring countries. Always verify the company holds an RCS registration before booking, especially for high-rise work where liability and insurance are critical.

Prices vary by access difficulty, the size and type of glazing, and whether frames and reveals are included in the scope. A basic ground-floor clean on a residential house falls at the low end of the per-m² range; a commercial building requiring a cherry picker or rope-access technicians sits firmly at the top.

Window cleaning professionals in Luxembourg price in one of two ways: per square metre of glazing, or per unit (per window or per opening). Understanding the difference matters for comparing quotes accurately.

Per-m² pricing is the most transparent method. The cleaner measures the total glazed surface — glass only, not the frame — and multiplies by the rate. A standard double-glazed unit of 0.8 m × 1.2 m = 0.96 m² of glass. At €8/m², that's roughly €8 per window.

Per-unit pricing is faster to quote but harder to compare. Rates of €5–12 per window are common for residential jobs, with skylights and Velux windows billed separately at €8–15 each due to the additional access and cleaning time required.

Always request the measurement methodology on the quote. A company quoting per-unit without specifying what counts as a unit — does a double window count as one or two? — creates ambiguity that can inflate the final invoice. The expat and international community in Luxembourg, which represents a significant share of premium residential clients, frequently reports this as the most common source of billing disputes with cleaning firms.

Access difficulty is the primary driver of price variation in window cleaning. Luxembourg has a mix of low-rise residential properties and mid-to-high commercial buildings, and each requires different equipment and qualifications.

Ground-floor and first-floor residential work is the simplest category. Cleaners use telescopic poles with water-fed brush systems, which allow cleaning from ground level without a ladder. This keeps costs low and avoids access negotiation.

Second floor and above — residential typically requires a ladder or a telescopic reach pole extended to 6–10 metres. Luxembourg buildings from the 1960s–1980s often have awkward overhangs or narrow access passages that make ladder work slow and expensive per unit.

Commercial mid-rise (3–6 floors) usually requires a cherry picker (nacelle élévatrice) or a bosun's chair. The cherry picker day rate runs €300–600 in Luxembourg, split across the windows cleaned that day — which is why per-m² rates for mid-rise commercial double relative to residential.

Rope-access technicians in Luxembourg must hold certified qualifications (IRATA or equivalent) and operate under a valid working-at-height risk assessment. Companies that cannot produce these documents should not be entrusted with high-rise jobs regardless of price.

For most residential properties in Luxembourg, the annual contract is better value — but the maths only works if the frequency matches actual need.

One-time cleaning suits properties being sold, post-renovation situations, or landlords turning over a rental. Expect to pay the full per-m² or per-unit rate with no discount. The lead time in peak periods (spring and autumn, when pollen and autumn rainfall create demand spikes) is two to four weeks.

Quarterly contract (4 visits/year) is the most common format in Luxembourg for residential clients. The typical saving versus four one-off bookings is 15–25% per visit, and the cleaner schedules the slot proactively rather than you needing to rebook each time.

Bi-annual contract (2 visits/year) makes sense for properties with limited glazed surface or low environmental exposure — a modern apartment in a low-pollution area. The discount over one-off rates is smaller, typically 10–15%.

Annual contracts in Luxembourg should be in writing, state the number of visits, define the scope per visit (inside glass, outside glass, frames, reveals), and specify the cancellation notice period. A verbal contract that a cleaner "will come every three months" is not enforceable and creates ambiguity on both sides. The expat market in particular should insist on written terms, as lease transitions and international relocations make cancellation clauses practically important.

Post-construction window cleaning is a distinct and more expensive scope than routine window cleaning. After building or renovation work, windows typically carry a combination of: cement splatter, silicone sealant overspray, paint spots, construction dust bonded to the glass surface, and protective film adhesive residue. None of these respond to the standard water-fed pole technique used for routine maintenance cleaning.

Post-construction cleaning requires specialist chemical treatments — typically an acidic cleaner for cement and mineral deposits, a solvent for adhesive residue, and a non-abrasive mechanical scraping tool for paint and sealant spots. The per-m² rate reflects the significantly higher product and labour costs involved.

At €8–20/m², post-construction cleaning on a new 200 m² house with 40 m² of glazing typically runs €320–800 for the glazing scope alone, excluding any associated facade or floor cleaning. Book a specialist firm, not a routine window cleaner — incorrect chemical use on low-emissivity (low-e) coated glass can permanently damage the coating, a repair that costs far more than the cleaning job itself. In Luxembourg's active construction market, this is a non-trivial risk on any building completed since 2010, when low-e glass became the standard specification.
