What “pure water / reach-and-wash” actually is — and why it dries spotless
The short answer: reach-and-wash means we pump purified water up a long carbon-fibre pole, scrub the glass and frames with a soft brush, and rinse — all from the ground. The water is run through deionisation (DI) resin and/or reverse osmosis (RO) to strip out the calcium and magnesium that ordinary tap water leaves behind as white spots. Mineral-free water is “hungry”: it lifts dirt off the glass, then dries with nothing left behind. No detergent, no smears, no ladders. Because the water-fed pole reaches windows up to roughly 60ft from the ground, there’s no need to lean ladders on your conservatory, fences or flowerbeds — which is also why it’s the method the HSE and the Federation of Window Cleaners point to under the Work at Height Regulations 2005.[1]
Why tap water leaves spots and pure water doesn’t
The short answer: tap water carries dissolved calcium and magnesium that dry onto the glass as white spots; purified (DI/RO) water has those minerals stripped out, so it evaporates clear with nothing left behind. That mineral difference is the entire reason pure water dries spotless and tap water doesn’t. If your windows go spotty as they dry — after rain, or after a previous cleaner — that’s the dissolved minerals in ordinary water drying onto the glass. Surrey sits on a mix of chalk and clay substrates, and chalk-area water carries a high calcium load that spots glass fast. Run the same water through DI resin or an RO membrane first and those minerals are gone, so it evaporates clear. That’s the whole trick — no wax, no polish, no chemical residue running into your drains or borders.
What you get every visit
A proper window clean isn’t just the glass. The pole brush reaches the frames, sills and doors too, so those get cleaned every single visit at no extra charge — something a traditional squeegee-and-cloth round simply can’t do from the ground. We text before we come, there’s no tie-in.
- Exterior glass cleaned with 100% purified water — dries spotless, no smears
- Frames, sills and doors cleaned at the same time, no extra charge
- Upper-floor and awkward windows reached safely from the ground
- No chemicals — nothing harmful into drains, soil or borders
- A text before we come, and a note to say we’ve been
- No contract, no tie-in — easy to start, easy to pause
Regular rounds vs one-off / first cleans
Most homes settle onto a 4-, 6- or 8-weekly cycle. The more often we come, the less build-up there is — so each maintained clean is quicker and cheaper per visit than letting it go. A first clean (or a one-off after a long gap) costs more, typically 50–100% above a regular visit, because there’s genuine dirt to shift. One honest heads-up: if your glass has older hard-water spotting or mineral stains baked in, that first clean may not come up perfectly with pure water alone — sometimes a one-off restorative pass is needed first. We’ll always tell you what’s realistic before we start so nobody’s surprised by a “still spotty” result.
Window cleaning prices in Surrey
Below are realistic Surrey bands from public 2026 cost guides[2] and our own local benchmark. The South East sits at the upper end of national rates. Exact price depends on the number and size of windows, access, and how often you have it done — a quick call gives you an exact figure.
| Property | Regular clean (per visit) | One-off / first clean |
|---|---|---|
| Terraced / flat | £18–£35 | £40–£60 |
| 3-bed semi | £20–£40 | £50–£90 |
| Detached | £35–£60 | £70–£120 |
| Townhouse (3 storey) | £25–£45 | £60–£110 |
| Conservatory roof clean | — | £150–£400 |
Per-window guide roughly £8–£15 in England. Committing to a 4–8 weekly round typically saves 15–30% versus one-offs. Conservatory roofs run roughly £8–£12 per panel — a small lean-to from £150, a large Victorian or Edwardian from £300–£400. Gutter clearing add-on roughly £30–£80. All figures are public-guide estimates — call 01737 652 515 for an exact quote.
One crew for the whole exterior
Because we’re already at your property with the pole and the pure water, we can clean more than just the windows on the same visit. That means one trusted local number instead of three different trades:
- Conservatory roofs & glass — soft-brush WFP from the ground, plus soft-wash for moss, lichen and algae on polycarbonate or glass panels
- Gutters, fascias & soffits — cleared and cleaned by pole or gutter-vac while we’re there
- Cladding & render frontages — pure-water or soft-wash for algae streaking
If you want the lot doing together, just say so when you call — see our render cleaning and commercial pages for bigger jobs.
Why a local Redhill crew
We’re a small two-man crew run by Patrick out of Redhill — the same faces every visit, not a faceless national or a gig-app subcontractor. We work to the HSE and Federation of Window Cleaners best-practice guidance for water-fed pole cleaning,[1] the same standards behind the Federation’s IOSH-approved WFP training.[3] Pure-water working from the ground is the direction the whole industry is moving in for safety — ground-based WFP cleaning was even raised in Parliament in late 2025 as the safe standard.[4] And if a clean’s ever not right, we’ll come back and sort it.
Areas we cover
Across all of Surrey within 20 miles of Redhill (RH1). That includes Redhill, Reigate, Crawley, Horley, Dorking, Banstead, and the rest of all 15+ areas.
