Complete Guide to Exterior Cleaning in Cornwall & Devon

The Ultimate Property Maintenance Resource for Homes & Businesses Across Coastal and Rural Areas

Cornwall and Devon are two of the most beautiful regions in the UK. From the harbours of St Ives and Falmouth to the streets of Truro, Newquay, St Austell, Penzance, Bodmin, Plymouth and Exeter — properties here face environmental conditions that are far harsher than most of the country.

Salt-laden air. High humidity. Mild winters. Heavy rainfall. Shaded lanes. Moss-heavy moorland areas.

All of these factors combine to create ideal conditions for:

Algae growth
Black spot (lichen)
Moss infestations
Render staining
Slippery patios and decking
Blocked gutters
Roof deterioration
Cladding discolouration

Exterior cleaning in Cornwall & Devon is not cosmetic. It is preventative maintenance that protects your property’s structure and long-term value.

Why Cornwall & Devon Properties Need More Frequent Exterior Cleaning

According to the UK Met Office, Cornwall and Devon experience higher humidity levels and milder winter temperatures than most inland regions. That means algae and moss don’t die off fully during winter — they continue to grow year-round.

Coastal towns such as:

Newquay
St Ives
Falmouth
Penzance
Padstow
Bude
Torquay

Experience salt spray and persistent moisture.

Inland towns and villages such as:

Bodmin
Launceston
Tavistock
Okehampton
Totnes
Ivybridge
Wadebridge
Liskeard

Experience heavy moss growth due to tree coverage and valley dampness.

Surfaces stay wet longer. Growth embeds deeper. Regrowth happens faster.

This is why exterior cleaning schedules in Cornwall & Devon should be proactive, not reactive.

Professional Pressure Washing in Cornwall & Devon

👉 https://jetpowerpressurewashing.co.uk/pressure-washing/

Pressure washing is one of the most effective ways to restore hard surfaces including:

Driveways
Patios
Paths
Concrete areas
Forecourts
Commercial hardstanding

Across Truro, St Austell, Newquay, Plymouth and Exeter, pressure washing removes years of embedded grime, algae and black spot.

However, pressure washing must be done correctly.

Too much pressure can:

Etch concrete
Damage block paving
Strip jointing sand
Scar natural stone
Force water into vulnerable areas

Professional surface cleaners ensure even results without striping or surface damage.

Pressure washing in Cornwall is not about brute force. It’s about controlled cleaning tailored to each surface type.

Gutter Cleaning: Essential in Cornwall & Devon’s Climate

👉 https://jetpowerpressurewashing.co.uk/gutter-cleaning/

Blocked gutters are one of the most expensive small problems homeowners ignore.

In leafy villages such as Feock, Devoran, Mylor, Polperro, Kingsand and Cawsand, gutters fill rapidly with:

Leaves
Pine needles
Moss from roofs
Wind-blown debris

When gutters overflow, water runs down walls rather than through downpipes.

This causes:

Damp penetration
Render staining
Fascia deterioration
Internal mould issues
Foundation oversaturation

Annual gutter cleaning is essential in Cornwall and Devon. Twice yearly is recommended for properties near trees.

This is one of the highest return-on-investment maintenance services available.

Soffit and Fascia Cleaning for Coastal Protection

White uPVC rarely stays white in Cornwall.

Salt air, algae film and traffic grime cause streaking and dullness — particularly in coastal towns like Newquay, St Ives, Falmouth and Penzance.

Professional soffit and fascia cleaning:

Restores brightness
Removes algae safely
Protects materials from long-term degradation
Complements gutter maintenance

Maintaining the roofline dramatically improves kerb appeal and extends lifespan.

Roof Cleaning & Moss Removal

👉 https://jetpowerpressurewashing.co.uk/roof-cleaning/

Roof moss is especially aggressive in:

Bodmin Moor areas
Dartmoor-edge towns
Liskeard
Launceston
Tavistock
Okehampton

Moss retains moisture against roof tiles. Over time this leads to:

Tile cracking
Blocked gutters
Water ingress
Structural damage

Professional roof cleaning typically uses soft washing methods to remove moss safely and apply treatment to reduce regrowth.

Pressure washing roofs is rarely appropriate and can cause serious damage if done incorrectly.

Roof cleaning protects one of the most expensive elements of your home.

Render Cleaning & Soft Washing

Modern homes across Truro, St Austell, Exeter and Plymouth often feature coloured render.

Render is highly susceptible to algae staining, particularly on north-facing or shaded walls.

Soft washing is the safest and most effective method for render cleaning because it:

Kills algae at the root
Restores original appearance
Prevents rapid regrowth
Protects delicate surfaces

This is especially important in coastal zones where humidity accelerates staining.

Decking Cleaning in Cornwall’s Damp Conditions

Wooden decking in Cornwall and Devon gardens becomes slippery quickly.

In villages such as Portreath, St Agnes, Mousehole and Perranporth, moisture levels remain high for much of the year.

Professional decking cleaning:

Removes algae safely
Avoids timber damage
Prevents splintering
Improves safety

Slip hazards on decking are a common issue in damp coastal environments.

Cladding Cleaning for Homes & Commercial Buildings

👉 https://jetpowerpressurewashing.co.uk/cladding-cleaning/

Commercial and industrial buildings in Truro, Camborne, Redruth, Plymouth and Exeter often suffer from dull and streaked cladding.

Cladding cleaning:

Restores professional appearance
Extends material lifespan
Enhances brand perception
Prevents permanent staining

This is particularly important for customer-facing businesses.

Commercial Exterior Cleaning Across Cornwall & Devon

First impressions matter.

Shops, schools, offices, industrial estates and retail parks in Truro, St Austell, Falmouth, Plymouth and Exeter all benefit from structured exterior cleaning.

Commercial services include:

Car park cleaning
Forecourt washing
Walkway algae removal
Wall and façade cleaning
Cladding restoration

Slip hazards caused by algae are a serious liability concern. Regular cleaning protects both safety and reputation.

How Often Should You Clean Exterior Surfaces?

Recommended schedule for Cornwall & Devon properties:

Gutters: 1–2 times per year
Driveways & patios: Every 12–18 months
Render: Every 2–4 years
Roof moss treatment: Every 3–5 years
uPVC roofline: Annually or bi-annually
Commercial properties: Ongoing maintenance plans

Coastal properties may require more frequent maintenance.

The Cost of Ignoring Exterior Maintenance

Neglecting exterior cleaning can result in:

Expensive roof repairs
Damp penetration
Structural damage
Increased slip risks
Reduced property value
Premature surface replacement

Preventative maintenance is significantly more cost-effective than repair or replacement.

DIY vs Professional Exterior Cleaning

DIY cleaning often leads to:

Uneven results
Surface damage
Rapid regrowth
Safety risks

Professional services use:

Commercial-grade equipment
Correct pressure settings
Specialist treatments
Fully insured processes
Proper safety procedures

This ensures safe and long-lasting results.
