Your Complete Guide for Truro, Newquay, Falmouth, St Austell, Penzance, Bodmin & Surrounding Villages
Living in Cornwall is incredible — but the coastal climate is tough on properties.
Salt air, high rainfall, shaded gardens and mild winters create ideal conditions for algae, moss and staining. Whether you’re in Truro, Newquay, Falmouth, St Austell, Penzance, Bodmin, Wadebridge, St Ives, Helston or surrounding villages, exterior cleaning is essential maintenance — not just cosmetic work.
Below are the 20 most common exterior cleaning questions Cornwall homeowners ask.
1. Why Does My Driveway Go Green So Quickly in Cornwall?
Cornwall’s damp climate allows algae to grow year-round. Shaded driveways and north-facing surfaces are particularly vulnerable.
Professional pressure washing removes embedded algae and restores safe, clean surfaces.

2. How Often Should I Have My Driveway or Patio Cleaned?
Most Cornwall homes benefit from cleaning every 12–18 months.
Properties near trees or the coast may need annual cleaning to prevent slippery buildup.
3. Can Pressure Washing Damage My Surfaces?
It can — if done incorrectly.
Too much pressure can:
- Etch concrete
- Strip block paving sand
- Damage stone
- Scar surfaces
Professional systems use controlled pressure and surface cleaners to avoid damage.
4. What’s the Difference Between Pressure Washing and Soft Washing?
Pressure washing uses controlled high-pressure water for hard surfaces like driveways.
Soft washing uses low pressure and specialist treatments for delicate surfaces like render.

5. Why Does My Render Turn Green in Coastal Cornwall?
Salt air + moisture + shade = algae growth.
Homes in Falmouth, St Ives and Newquay often see faster staining due to coastal humidity.
Soft washing kills algae at the root for longer-lasting results.
6. Is Roof Moss Actually a Problem?
Yes.
Moss retains moisture against roof tiles, which can lead to:
- Tile damage
- Blocked gutters
- Water ingress
Professional roof cleaning safely removes moss and reduces regrowth.

7. How Often Should Gutters Be Cleaned in Cornwall?
At least once per year.
Leafy villages like Feock, Devoran and Probus may require twice-yearly cleaning due to debris buildup.

8. Can Blocked Gutters Cause Damp?
Absolutely.
Overflowing gutters allow water to run down walls, leading to damp patches, staining and internal moisture issues.
9. Is Decking Cleaning Necessary?
Yes — especially in damp Cornish gardens.
Algae-covered decking becomes extremely slippery.
Professional decking cleaning improves safety and extends timber lifespan.
