Window cleaning in London

Describe the windows accurately

Count the windows and mention large panes, bays, patio doors or conservatory sections. Say whether the frames are sash, casement or another style if you know. Include the floor level and any extensions that affect access. The cleaner needs more information than the number of bedrooms. A small house with a glass extension may have much more glazing than a larger house without one. Photographs can help explain the arrangement if requested. Tell us about painted frames, delicate finishes or recent work. This helps distinguish a straightforward window clean from a task involving building residue or specialist care.

Inside and outside are separate choices

Make clear which sides you want cleaned. External windows can be discussed independently from internal glass, and access to one side does not mean the other is reachable. If you want frames, sills or tracks included, ask what the quote covers. A standard glass clean should not be assumed to include every surrounding fitting or a conservatory roof. Tell us about insect screens, shutters and any window that does not open normally. If you rent a flat, check building arrangements and access permissions where appropriate. Clear scope avoids arriving to find that half the work relies on access that has not been arranged.

Access and safe working conditions

Explain gates, locked courtyards, narrow side passages and any parking restrictions. Say whether windows sit above a conservatory, extension or basement area. Do not offer an unsafe way to reach a pane or assume the cleaner can stand on a fragile roof. The team needs to confirm what can be accessed safely with the proposed equipment. If a window cannot be reached, the scope may need to change. Indoor access also matters: furniture, blinds and ornaments can block the glass. Arrange a clear working area and tell us about pets or rooms that must remain locked during the visit.

Marks that ordinary cleaning may not remove

Some marks are not everyday dirt. Paint, adhesive, cement residue and hard-water staining can need a separate discussion. Scratches, etched surfaces and internal condensation cannot be removed by wiping the outside. Tell us if the windows have recently been installed or if building work has taken place. Do not scrape the glass yourself with an unsuitable blade while waiting for the visit. Coatings and specialist glass can be damaged by the wrong method. The cleaner may need to assess the material and the residue before confirming what can be attempted. A realistic explanation is more helpful than a promise of perfect glass in every condition.

Prepare the inside of the property

Remove ornaments, papers and small items from sills where possible. Give the cleaner access to the booked windows and explain how any shutters or fittings should be handled. If furniture needs moving, discuss it in advance rather than expect a heavy item to be lifted on arrival. Let us know about alarms, entry codes and windows that cannot be opened. Keep fragile items somewhere secure and give instructions for pets. The aim is not to have you doing the cleaning first, but to make the agreed glass reachable. Preparation is especially useful in a furnished home with crowded sills or narrow rooms.

Timing and repeat visits

How often to clean windows depends on the property, its surroundings and what matters to you. Traffic, trees, exposed weather and building work can affect how quickly dirt returns. You can enquire about a one-off visit or discuss repeated appointments if available for your address. Weather and safe access can affect external work, so confirm the arrangements rather than rely on an unconditional attendance promise. If you are preparing for a sale, inspection or event, mention the date and leave sensible time. Tell us when other work will be finished so freshly cleaned windows are not immediately covered by dust from continuing trades.

Guide prices and minimum charges

The public price list gives some window-cleaning starting rates from £33, but it also states a £42 minimum charge. A starting item price below the minimum should not be understood as the full payable total. Ask for a quote for your own windows, sides, frames and access. Property type, number of windows, height, location and availability can affect the cost. Congestion charges may apply. Conservatories and other glazing may have separate rates. Keep the quote clear enough to compare with the job: which windows, which sides and what surrounding work is included. That is more useful than choosing a service by a small headline price alone.

Cleaning and glazing are different services

If the glass is broken, misted between panes or part of a damaged frame, explain the issue before asking for cleaning. You may need glazing or repair advice instead. Cleaning is not a repair to a sealed unit, a fix for leaks or a test of the window’s security. Our window glazing page explains the information useful for that enquiry. Keeping the two services separate avoids paying for a clean when the main concern cannot be solved by cleaning.

Questions about window cleaning

Can every upstairs window be reached?

Not automatically. Describe the height, obstacles and access. The team will confirm what is suitable for the proposed equipment and may need photographs or further information before agreeing the full scope.

Are paint marks included?

Mention paint or building residue separately. It may need different treatment, assessment or a different price. Do not assume a routine window clean covers removal of hardened material from all types of glass.

Does window cleaning fix internal misting?

No. Misting between panes is different from dirt on the exposed glass. Describe the problem when enquiring so it can be directed to the appropriate glazing discussion rather than a cleaning appointment.
