Why You Might Need Soft Washing
Soft washing is essential for protecting your building, especially in Cornwall’s damp, coastal environment where algae and organic growth thrive.
1. Remove Algae, Mould & Black Staining
Cornwall’s climate causes rapid algae growth—soft washing removes it safely and keeps it away for longer.
2. Protect Delicate Surfaces
Render, roofs and painted walls can be damaged by pressure washing. Soft washing avoids cracks, etching and water penetration.
3. Improve Kerb Appeal
A clean exterior instantly lifts your home’s appearance—ideal for home sales, holiday lets or rental properties.
4. Longer-Lasting Results
The specialist biocide continues working for months, preventing regrowth.
5. Prevent Structural Damage
Moss and algae trap moisture, which can lead to cracks, staining and long-term deterioration.
6. Eco-Friendly Solutions
We use approved, biodegradable softwash solutions that are safe for your property and landscaping.
