Reading sits in a hard water area, which changes window cleaning from a simple job into a technical one. Tap water here carries a high dissolved mineral content, so rinsing glass with it and letting it dry leaves a white mineral film — the spotting people assume is dirt but is actually limescale deposited by the rinse itself. Cleaning windows properly in RG1 means dealing with that before anything else.
Purified water, and why it matters here
Professional window cleaning uses water passed through filtration and deionisation until the dissolved solids are effectively removed. Pure water is aggressive — it actively pulls dirt off glass — and, critically, it dries without leaving a residue, so the glass can be left to dry naturally rather than squeegeed and buffed. That is what allows a telescopic pole to reach upper-floor windows from the ground safely, and it is why professionally cleaned windows in a hard water area stay clear for weeks longer than ones rinsed with a hose.
Frames, sills and the parts that get skipped
A proper clean includes the frames, sills and glazing beads, not just the glass. This matters more than it sounds: dirt held in the frame runs down onto clean glass at the first rain, which is why a glass-only clean looks poor again within days. uPVC frames that have gone grey or yellow can be brought back with an appropriate cleaner, and it is worth asking for that as a one-off rather than assuming the discolouration is permanent. Where there are trickle vents, these get cleared too, since blocked vents contribute directly to condensation problems indoors.
Period glass and conservation streets
Parts of central Reading have older properties with original or early glass, timber sashes and painted frames. Old glass is softer and less even than modern float glass and should not be scraped; painted timber frames should not be saturated. These are handled with lower-pressure pure water and hand detailing where needed, rather than the standard pole routine.
What causes the dirt in the first place
Two things account for most repeat soiling. The first is an overflowing gutter directly above a window, which deposits silt and organic matter down the glass every time it rains — the team covering Reading deals with the cause rather than the symptom, and doing it before a window clean is the sensible order. The second is splash-back from an untreated path or driveway below, which throws grit onto the lower panes: pressure washing specialists in Reading covers that.
Coverage and frequency
Every four to eight weeks suits most households, with quarterly enough for a sheltered property and monthly better on a busy road. The same teams work across Berkshire and Wiltshire, so local window cleaning across Swindon runs on identical terms if you have a property further west. Properties coming out of building work need the paint, plaster and mortar splashes removed before a routine clean will achieve anything — Wokingham post-renovation cleaning covers that specification nearby.
Booking
Pricing is by property size and window count, confirmed before the visit, with no contract and no obligation to keep a recurring slot. Cleaners are insured and use pure water systems with reach-and-wash poles for upper floors rather than ladders wherever possible. Full details of what is covered are on the full service page, and live availability for Reading is online.
Inside, conservatories and access
Interior glass is a separate line from exterior and is usually booked less often — twice a year suits most households. Conservatory roofs are priced separately again because they need a different approach and considerably more time, and are worth doing before summer rather than after. For upper-floor windows the reach-and-wash pole covers most domestic properties from the ground; where a window cannot be reached safely that way, access equipment is quoted rather than improvised.
You do not need to be home for an exterior clean as long as side access is available and gates are unlocked. Let the cleaner know about pets in the garden. Bookings are made and amended online.
