The Safer, Longer-Lasting Alternative to Pressure Washing
Not every exterior surface can withstand the force of a pressure washer. Render, cladding, timber, and many other materials can be damaged by high-pressure water, leading to costly repairs. Soft washing provides a safe, highly effective alternative that cleans thoroughly and keeps surfaces cleaner for longer. Our professional soft washing service in Redhill, Reigate and across Surrey uses low-pressure water combined with specialist biodegradable cleaning solutions to remove algae, mould, lichen, and organic staining from any exterior surface.
The key advantage of soft washing is that it doesn't just remove surface growth - it kills the organisms at root level. This means your walls, roof, or cladding stay cleaner for 2-4 years, compared to 6-12 months with pressure washing alone. For homeowners who want lasting results without the risk of surface damage, soft washing is the clear choice.
What is Soft Washing?
Soft washing is a professional cleaning method that uses low-pressure water (under 500 PSI) combined with specially formulated cleaning solutions. Unlike pressure washing, which relies on force to remove dirt and growth, soft washing uses chemistry to break down and kill biological growth such as algae, mould, mildew, and lichen.
The cleaning solutions we use are biodegradable and specifically designed for exterior building surfaces. They penetrate into the surface, killing growth at the root and spore level. After treatment, the dead biological matter is rinsed away with low-pressure water, leaving a clean surface that resists recolonisation for years.
Surfaces We Soft Wash
Render (K-Rend, Silicone, Painted)
Rendered walls are the most common reason homeowners in Surrey contact us for soft washing. K-rend, silicone render, and painted render all attract algae and mould growth, creating unsightly green and black streaks. Many newer developments in Redhill, Horley, and Crawley use rendered finishes that look fantastic when new but quickly become discoloured without maintenance. Pressure washing render risks damaging the surface finish, but soft washing cleans it safely and effectively. See our render cleaning page for more details.
Cladding (UPVC, Timber, Composite)
Cladding panels accumulate dirt, algae, and atmospheric pollution over time. UPVC cladding turns grey and dull, timber cladding develops green algae growth, and composite panels lose their colour. Soft washing restores all cladding types to their original appearance without warping, cracking, or forcing water behind panels.
Roofs (Tiles, Slate, Flat)
Soft washing is the recommended method for roof cleaning. High-pressure washing can crack tiles, strip protective coatings, and force water under the roof covering. Our soft wash biocide treatment kills moss, lichen, and algae on all roof types, with results that last 3-5 years.
Conservatories
Conservatory roofs and frames accumulate green algae and bird droppings that diminish light transmission and look unsightly. Soft washing safely cleans polycarbonate, glass, and UPVC frames without risk of cracking or scratching.
Natural Stone and Brick
Older properties in Reigate, Dorking, and Betchworth often feature natural stone or period brickwork that cannot withstand high-pressure cleaning. Soft washing removes biological growth while preserving the character and integrity of heritage materials.
Fencing and Garden Structures
Timber fences, pergolas, and garden structures respond well to soft washing. The treatment removes green growth and restores the wood's natural appearance without the splintering that can occur with pressure washing.
Benefits of Soft Washing
- Longer-Lasting Results - Kills growth at root level, keeping surfaces cleaner for 2-4 years versus 6-12 months with pressure washing
- Safe for Delicate Surfaces - Low pressure means no risk of damage to render, cladding, timber, or roofing materials
- Effective on All Growth Types - Removes algae, mould, mildew, lichen, and organic staining that pressure alone cannot eliminate
- No Water Ingress Risk - Low-pressure application doesn't force water into wall cavities, behind cladding, or under roof tiles
- Biodegradable Solutions - Our cleaning products are environmentally responsible and safe for use near gardens
- Cost-Effective - Longer intervals between cleans mean lower annual maintenance costs compared to repeated pressure washing
Our Soft Washing Process
1. Surface Assessment
We assess the surface type, condition, and extent of biological growth. This determines the correct cleaning solution concentration and application method. We identify any areas of existing damage that need to be worked around.
2. Preparation & Protection
All nearby plants, garden furniture, and surfaces are protected. Vegetation is thoroughly wetted down to prevent absorption of cleaning solution. Windows and doors are closed, and any sensitive items are covered or moved.
3. Solution Application
The specialist cleaning solution is applied evenly across the surface using low-pressure spray equipment. The solution is left to dwell for the appropriate time, allowing it to penetrate and kill biological growth at the root level.
4. Rinse & Inspection
The surface is rinsed with low-pressure clean water to remove dead growth and cleaning solution residue. We inspect the results, addressing any areas that need additional treatment. All surrounding areas are rinsed clean.
Soft Washing vs Pressure Washing: When to Use Each
Both soft washing and pressure washing have their place. Here's a guide to which method suits different surfaces:
Use soft washing for: Render (all types), cladding, roofs, conservatories, natural stone walls, timber structures, painted surfaces, heritage buildings, and any surface where high pressure risks damage.
Use pressure washing for: Driveways (concrete, tarmac, block paving), patios (concrete slabs, porcelain), garage floors, and other hard, durable ground surfaces where force is needed to shift ingrained dirt and staining.
