Commercial equipment, professional chemistry
Results like these aren't possible with supermarket sprays and a domestic vacuum. Here's what our teams bring to every job.
HEPA vacuum systems
Commercial vacuums with sealed HEPA filtration capture fine dust and allergens instead of recirculating them into the air.
Hot-water carpet extractor
Professional extraction injects heated solution deep into fibres and pulls the loosened soil straight back out.
Steam cleaners
High-temperature dry steam sanitises grout, seals and hard surfaces chemical-free — ideal around children and pets.
Professional chemistry
Trade-grade degreasers, descalers and enzyme treatments matched to each surface rather than one all-purpose spray.
Colour-coded microfibre
Separate cloth systems per zone prevent cross-contamination between kitchens, bathrooms and living areas.
Eco-certified products
Biodegradable, low-odour solutions that deliver a professional finish without harsh residue.
Everything you need to know about window cleaning in London
Pure-water window cleaning across London
London glass takes a beating. Traffic film, brake dust, pollen and hard-water spotting build into a grey haze that you stop noticing until the day it is cleaned. We clean exterior glass using a pure-water reach-and-wash system: mains water is filtered and de-ionised until every dissolved mineral is stripped out, then fed through a telescopic pole to a brush head. The brush agitates the dirt, the pure water rinses it, and because there is nothing dissolved in the water there is nothing left behind to dry into streaks or spots.
The practical benefits matter as much as the finish. No ladders resting against your brickwork, no detergent running down the render, and frames, sills and rubbers get washed as part of the same pass rather than left dirty around clean glass.
What is included
- Exterior glass cleaned by pure-water reach-and-wash, typically up to four storeys from ground level
- Frames, rubbers, sills and ledges washed as part of the same pass
- Interior panes cleaned and polished streak-free where interior work is booked
- Interior sills, tracks and ledges wiped out
- Conservatory roofs, skylights and glazed doors where safely reachable
- Glazed partitions, balustrades and mirrors on request
- Shopfronts, entrance glass and communal glazing for commercial clients
How the visit works
We confirm the property type, the number of windows and the access before booking, then attend with the water already filtered and stored on the vehicle. Exterior glass is cleaned from the ground with the pole system, working systematically around the property. Interiors, when booked, are cleaned traditionally with applicator, squeegee and microfibre, with the floor protected under each window. There is no chemical smell and nothing to wipe up afterwards. Most terraced and semi-detached homes take under an hour for exteriors; larger properties, conservatories and full interior work take longer.
Glass looks best when it is cleaned regularly rather than rescued occasionally. Many London households book every four, eight or twelve weeks, and regular visits are quicker and cheaper per visit than one-off deep cleans of neglected glass.
Equipment
De-ionising and reverse-osmosis filtration, on-board water tanks, carbon-fibre telescopic poles with soft brush heads, TDS meters to confirm the water is genuinely pure before we start, traditional applicators, professional squeegees, scrim and microfibre for interiors, detail brushes for tracks and vents, and non-marking floor protection indoors.
Transparent pricing
Window cleaning starts from £35. Price depends on the number and size of windows, the number of storeys, whether interiors are included, and whether extras such as conservatory roofs, skylights, French doors or Georgian-bar glazing are involved. Regular schedules are priced per visit and are more economical than one-off calls. First cleans on heavily neglected glass sometimes carry a one-off restoration charge, which we tell you about upfront rather than after the job.
Preparing for the visit
Please make sure side gates are unlocked and rear access is clear, move garden furniture, bins or planters away from the windows, close all windows before we arrive, and keep pets indoors while we work at the rear. If you are booking interiors, clear window sills and pull curtains or blinds back. Tell us about restricted parking, permit zones, communal entry systems and any windows that cannot be opened or are known to leak.
Honest limitations
Cleaning removes what sits on the glass. It cannot fix what is wrong with the glass. Misted or blown double glazing is a failed seal with condensation trapped inside the unit, and no amount of cleaning reaches it — that needs the unit replaced. Scratches, hard-water etching, cement splashes that have burned into the surface, and paint or render spatter from previous works may not come off fully, and aggressive attempts to remove them risk damaging the glass. Windows above safe reach, or those requiring roof access, cradles or scaffolding, are outside our scope. Perished frame seals and rotten timber will be cleaner but not repaired. We will always tell you before we start if we can see something that will not come off.

Window Cleaning — your questions answered
Window cleaning starts from £35. The final price depends on the number of windows, the property type, the height and access, whether balconies, skylights or a conservatory roof are included, and the current condition of the glass and frames.
Exterior glass is cleaned with filtered, de-ionised water fed through a telescopic pole and brush. Because the water contains no minerals, it dries without leaving spots or streaks, and no detergent runs onto planting, brickwork or paintwork.
Yes. Interior window cleaning is a separate part of the quote and covers the internal glass, sills and accessible frames, cleaned by hand with microfibre and glass-safe solution.
Exterior frames and sills are cleaned as part of the pure-water pass where they are included in your quote. Heavily stained, painted, rusted or algae-covered frames may need a separate restorative clean, which we quote after seeing photos.
Yes, where they can be reached safely and where they have been included in the quote. Roof glass, Velux units and conservatory roofs are always priced separately from standard windows.
No. Cleaning removes dirt, dust, pollution film and loose deposits. Scratches, mineral etching burnt into the glass, cloudiness caused by failed double-glazing seals, paint splashes from previous works and building damage are not cleaning issues and will remain.
Pure water leaves no detergent residue behind, so ordinary rain does not create streaks. Heavy driving rain or nearby building works can of course carry new dirt onto the glass.
Access to the outside of the property, gates unlocked, cars moved where they block reach, and pets kept indoors. For interior cleaning, please clear window sills of ornaments, plants and blinds where possible.
Yes. Many clients book repeat visits — monthly, six-weekly or quarterly — and we agree the interval that suits the property and its exposure.
Access and safety. Pure-water poles cover a considerable height from ground level, but restricted rear access, balconies, obstructions and anything beyond safe reach may need alternative access, which we assess and quote before booking.
