If you’re searching for exterior cleaning prices in Cornwall or Devon, you’re probably wondering what you should expect to pay — and whether quotes you receive are fair.
Exterior cleaning costs vary depending on surface type, contamination level, access, and property size. In this 2026 pricing guide, we explain typical cost ranges across Cornwall and Devon, what affects pricing, and how to avoid false economy quotes.
What Affects Exterior Cleaning Prices in Cornwall & Devon?

- Heavy rainfall and persistent damp
- Coastal salt exposure
- Rapid algae and moss growth
- Difficult access in older town centres

- Level of biological growth
- Size of area
- Required cleaning method (soft wash, steam, pressure wash)
- Access requirements (height, restricted spaces)

Small patio (20m²): £120 – £250
Medium patio (40m²): £200 – £450

£120 – £250 for larger properties
Homes near trees or the coast may require cleaning twice per year. Regular gutter cleaning in Cornwall prevents costly damp and render damage.
Roof Cleaning Cost

£800 – £2,500+ depending on size and moss levels
Roof cleaning is labour-intensive and safety-sensitive. Soft washing and moss removal prevent blocked gutters and tile damage.

£100 – £300 for most residential properties
Professional soffit and fascia cleaning in Cornwall restores rooflines and improves kerb appeal.

Why Prices in Coastal Cornwall & Devon May Be Higher
Properties in coastal towns such as:
- St Ives
- Penzance
- Torquay
- Paignton
often experience:
- Faster algae regrowth
- Heavier contamination
- Salt-induced surface wear
This may require more intensive cleaning methods.
Why the Cheapest Quote Can Cost More
Low-cost quotes often mean:
- No biological treatment
- Overuse of pressure (surface damage risk)
- No insurance cover
- No long-term prevention
Professional cleaning focuses on correct method selection, not just speed.
