Your home’s exterior takes a daily beating from the British weather — rain, damp air, and shade all combine to create the perfect breeding ground for algae, moss, lichen, and black streaking. Left untreated, this buildup doesn’t just look unsightly; it can slowly eat into render, brickwork, cladding, and roofing materials, leading to costly repairs down the line.
That’s where soft washing comes in. Unlike high-pressure jet washing, soft washing uses low-pressure application combined with specialist biocidal treatments to safely kill and remove algae, moss, mould, and organic growth at the root — without damaging delicate surfaces.
At CPC Services Group, we’ve made soft washing one of our core specialisms, delivering safe, long-lasting results for homeowners, businesses, and holiday parks across Hampshire and West Sussex.
What Is Soft Washing?
Soft washing is a low-pressure exterior cleaning method that uses a specially formulated cleaning solution to break down and eliminate organic growth such as:
- Green and black algae
- Moss and lichen
- Mould and mildew
- General atmospheric grime and pollution staining
Because the process relies on chemistry rather than force, it’s far gentler on your property than traditional pressure washing — making it ideal for render, pebbledash, cladding, roof tiles, and painted surfaces that could otherwise be damaged by high-pressure water.
Why Soft Washing Is Essential for Your Property
Many homeowners don’t realise that the green and black staining on their walls and roof isn’t just cosmetic — it’s a sign of active biological growth that continues to spread if left untreated.
Here’s why soft washing matters:
- Protects your investment – Algae and moss retain moisture against surfaces, which can accelerate wear, cracking, and damp issues over time.
- Prevents costly repairs – Removing organic growth early avoids more expensive render, roofing, or cladding repairs later.
- Improves kerb appeal – A clean exterior significantly boosts how a property looks and how it’s perceived by visitors, buyers, or guests.
- Extends the life of surfaces – Regular soft washing keeps render, brick, and roofing in better condition for longer.
- Safe for delicate materials – Ideal for surfaces that pressure washing could crack, chip, or strip.

Our Soft Washing Process
- Free On-Site Assessment – We inspect the property and identify the type and extent of organic growth.
- Surface Protection – Plants, pathways, and surrounding areas are protected before treatment begins.
- Application – A biodegradable, low-pressure treatment is applied to break down algae, moss, and grime.
- Dwell Time – The solution is left to work, killing growth at the root rather than just removing surface staining.
- Rinse & Finish – A final low-pressure rinse leaves surfaces clean, refreshed, and protected.
Many customers see continued improvement over the days following treatment, as the biocidal solution continues working after the visit.
Soft Washing vs Pressure Washing — What’s the Difference?
A common question we get is why soft washing is often recommended over standard pressure washing.
| Soft Washing | Pressure Washing | |
|---|---|---|
| Pressure used | Low | High |
| Best for | Render, roofs, delicate surfaces | Driveways, patios, hard surfaces |
| Root cause treatment | Yes – kills growth at the root | No – removes surface only |
| Risk of surface damage | Very low | Higher on soft materials |
| Longevity of results | Longer-lasting | Shorter-lasting regrowth |
We assess every property individually and recommend the right method — or a combination of both — depending on the surface and level of buildup.

Frequently Asked Questions
How often should soft washing be done?
Most properties benefit from soft washing once every 12–18 months, though shaded or damp-prone areas may need more frequent treatment.
Is soft washing safe for my plants and pets?
Yes. We use biodegradable solutions and take care to protect surrounding planting during the process.
Will soft washing damage my render or roof tiles?
No — this is precisely why soft washing is recommended over pressure washing for these surfaces. The low-pressure method cleans effectively without causing physical damage.
How long do the results last?
Because soft washing treats the root cause of growth rather than just surface staining, results typically last significantly longer than pressure washing alone.
