Window Cleaning & Exterior Services Across the Helderberg
Window Cleaning
Pure water cleaning for all glass types — float, tempered, laminated, low-E and double-glazed IGU — and all frame types including aluminium, timber and uPVC. Streak-free finish, ladder-free up to triple-storey.
Skylight Cleaning
Roof glass, atrium glazing and skylights cleared of lichen, bird droppings and pollen. Crucial in shaded Somerset West and Paardevlei properties where biofilm builds up fast.
Gutter Clearing
Pine needles, leaves and debris removed before the Cape winter rainfall season. Prevents fascia rot, ceiling damp and overflow during heavy May–August downpours.
Solar Panel Cleaning
Manufacturer-compliant pure water cleaning for monocrystalline and polycrystalline PV panels. Recovers up to 7% of soiling losses — meaningful kWh during loadshedding.
Signage & Shopfront Cleaning
Retail signs, shopfront glass and corporate branding cleaned without abrasive chemicals. Once-off or scheduled monthly contracts from R450.
Aluminium Frame Cleaning
Salt-spray oxidation and white powder build-up removed from aluminium window frames in Strand, Gordon's Bay and coastal Helderberg homes.
Why Pure Water Window Cleaning Is the Gold Standard
Traditional window cleaning leaves behind detergent residue and mineral spotting that re-attract dust within days. Our pure water system filters Cape Town municipal water through three stages — sediment filtration, reverse osmosis (RO) and deionising resin — until total dissolved solids drop to 0 ppm. With nothing dissolved in the water, it actively pulls grime off the glass and dries spot-free, with no chemicals, no streaks and no need for hand-finishing.
The water is delivered through a carbon-fibre water-fed pole with a soft brush head — reaching up to 9 metres / triple-storey safely from the ground. That means no ladders against your gutters, no scaffolding on your driveway, and no team members at height risk. It's also up to 80% faster than traditional squeegee work, which is why we can offer competitive prices on monthly maintenance contracts.
For solar panels in the Helderberg, pure water is the only safe choice. Modern PV panels (JinkoSolar, Canadian Solar, JA Solar, LONGi, Trina) carry a delicate anti-reflective coating that detergents and acidic cleaners permanently degrade — silently reducing your generation by 1–3% forever. Pure water plus a soft brush is the manufacturer-recommended method.

Window Cleaning Somerset West — Frequently Asked Questions
How much does window cleaning cost in Somerset West?
A standard 3-bedroom home with 15–20 windows ranges from R600–R1,200. Double-storey homes typically run R1,200–R2,000. Estate homes with skylights range R2,000–R3,500. We provide free, no-obligation quotes via WhatsApp.
Do you service Erinvale, Spanish Farm, Heritage Park and Paardevlei?
Yes — we service every major estate in Somerset West, including Erinvale Golf Estate, Spanish Farm, Heritage Park, Paardevlei, Croydon Olive Estate and Parel Vallei. We're set up for boom-gate access and gated-community protocols.
Why are Strand and Gordon's Bay windows dirtier than Somerset West windows?
Salt aerosol from False Bay carries up to 2 km inland on the south-easter (the Cape Doctor). Coastal homes within 500 m of the beach can show visible salt build-up within 14 days, which is why monthly cleaning is recommended for Strand and Gordon's Bay properties.
What is pure water cleaning and why is it better?
Pure water is municipal water filtered through reverse osmosis (RO) and deionising resin until it reaches 0 ppm TDS (Total Dissolved Solids). With nothing dissolved in it, the water actively pulls grime off the glass and dries streak-free without any soap, chemicals or hand-finishing.
Will chemical cleaners damage my solar panels?
Yes. Most modern PV panels (JinkoSolar, Canadian Solar, JA Solar, LONGi, Trina) have an anti-reflective coating that detergents and acidic cleaners can permanently degrade, reducing output. We use only pure water and soft brushes, in line with manufacturer guidelines.
How high can your water-fed poles reach?
Our carbon-fibre water-fed poles reach up to 9 metres / triple-storey — comfortably handling triple-storey homes and buildings without ladders, scaffolding or rope access. Safer for our team and no ladders against your gutters or aluminium frames.
How often should I clean my solar panels in Somerset West?
Every 3 months for inland properties; every 6–8 weeks for coastal homes in Strand or Gordon's Bay. Soiling losses of 3–7% are typical in the coastal Western Cape — meaningful during loadshedding when every kWh extends battery autonomy.
When is the best time to clean gutters in the Helderberg?
Late March to mid-April, before the Cape winter rainfall season starts in May. Pine-heavy areas like Paardevlei and Spanish Farm often need a second clear in mid-July.
Are you insured if something gets damaged?
Yes — Window Ninja carries public liability insurance.
Do you work safely at height on double-storey homes?
Yes. Our pure-water pole system means most double-storey and triple-storey homes are cleaned entirely from ground level — safer for our team, faster than ladder work, and no ladders against your gutters or aluminium frames.
What cleaning products do you use?
For ground-floor windows we use Sunlight to cut grease. For high-reach windows, solar panels and skylights we use our pure water system (0 ppm TDS) — no soap or chemicals — for a streak-free, residue-free finish.
Can dirty solar panels really cost me money during loadshedding?
Yes. Soiling losses of 3–7% are typical in coastal Cape Town. On a 5kW system, that's 600–1,400 kWh per year — enough to noticeably extend your battery's autonomy during evening loadshedding slots.
Do you do once-off shopfront cleans or only contracts?
Both. Once-off signage and shopfront cleans from R450, plus weekly, fortnightly and monthly maintenance contracts for offices, retail, estate common areas and industrial sites.
What happens if it rains on my scheduled day?
If there's heavy rain or dangerous wind on your scheduled day, we'll contact you to move your appointment to the next available clear day at no extra cost. Light drizzle does not affect pure water cleaning results.
What happens if I'm not happy with the result?
We don't leave site until you're satisfied. If you spot anything within 24 hours of the clean, we return at no cost. This applies to every job in Somerset West, Strand, Gordon's Bay, Helderberg and Paarl.
