Terms and conditions

These general terms and conditions apply to all contracts for glass and window cleaning between Glasklar Fensterdienst e.K., Jungbuschstraße 22, 68159 Mannheim (“Glasklar”) and its clients (“the client”).

Differing terms proposed by the client become part of the contract only if Glasklar expressly agrees to them in writing. This also applies where Glasklar performs the work without reservation while aware of conflicting terms.

The prices shown on this website and the result of the pane calculator are non-binding estimates and do not constitute an offer in the legal sense.

A contract is formed when Glasklar confirms an enquiry in writing or by email, or begins the work and the client does not immediately object.

Only the price stated in the order confirmation is binding. If the actual scope on site differs substantially from the client's own count, Glasklar will say so before starting work; the client may then adjust or cancel the order free of charge.

Glasklar cleans glass surfaces including frames and sills. The contract does not cover gutters, roofs, photovoltaic modules, façade surfaces, interior room cleaning, or work using rope access techniques.

Cleaning is carried out with deionised water and without detergents. Pre-existing damage such as scratching, corrosion, blind insulating glazing, burnt-in limescale or bonded construction dirt cannot be remedied by cleaning. Glasklar points out such findings before starting; they do not constitute a defect in the cleaning work.

Work above roughly eight metres working height, and glass restoration work, are quoted separately after an inspection.

The client ensures that the surfaces to be cleaned are accessible, that sills are cleared, and that, where necessary, a water supply and a power socket may be used. The resulting cost of water and electricity is negligible and is not charged separately.

If Glasklar is unable to carry out the agreed work for reasons within the client's responsibility, § 6 applies accordingly.

All prices are in euros and include statutory value added tax.

The invoice is issued after the work has been carried out and is payable in full within 14 days of the invoice date by bank transfer. Cash payment is not possible.

For private clients the labour element is shown separately on the invoice so that it can be claimed as a household-related service under § 35a of the German Income Tax Act.

In the event of late payment, the statutory rules apply.

Appointments are binding. If the client cancels later than 24 hours before the agreed start, or if the property is not accessible at the agreed time, Glasklar may charge 50 per cent of the agreed price as compensation. The client remains free to prove that the actual loss was lower.

In frost below minus two degrees Celsius, in winds of force 6 or above, or during thunderstorms, Glasklar may postpone outdoor work for reasons of occupational safety. A replacement appointment is offered promptly; there is no claim for damages arising from the postponement.

Rain after cleaning is not a defect and does not give rise to a claim for re-cleaning.

Contracts for recurring cleaning rounds are concluded for an indefinite period and invoiced monthly.

Either party may terminate the contract in text form with four weeks' notice to the end of a month. The right to terminate for good cause remains unaffected.

If a scheduled visit falls on a public holiday in Baden-Württemberg, it moves to the next working day.

The client notifies apparent defects in the cleaning work within two working days of completion. Glasklar remedies justified defects free of charge.

Only after a reasonable period set for remedy has expired without success may the client exercise the statutory rights to reduce the price or withdraw from the contract.

In all other respects the statutory warranty provisions apply.

Glasklar carries business liability insurance covering personal injury, damage to property and consequential financial loss. The current certificate of insurance is provided on request before work begins.

Glasklar is liable without limitation for intent and gross negligence and for injury to life, body or health. In cases of slight negligence in breaching a material contractual obligation, liability is limited to the foreseeable loss typical of this type of contract. Any further liability is excluded.

Glasklar is not liable for damage to glass, frames, seals or fittings that already existed before work began. Such pre-existing damage is documented before starting, insofar as it is apparent.

No contracts are concluded through this website; there is no online sale. Where a contract is concluded exclusively by telephone, by email or at the client's home, consumers have a statutory right to withdraw within 14 days of conclusion.

Withdrawal is possible without formality, for example by email to hallo@glasklar-fensterdienst.de. We provide separate instructions on the right of withdrawal and its consequences in text form before the contract is concluded.

If the client expressly requests that work begin before the withdrawal period expires, a proportionate amount is owed for the work performed up to a later withdrawal.

Personal data is processed exclusively in order to perform the contract. Details are set out in the privacy policy on this website.

The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods.

If the client is a merchant, a legal entity under public law or a special fund under public law, Mannheim is the exclusive place of jurisdiction.

Should any provision of these terms be or become invalid, the validity of the remaining provisions is unaffected.
