How Often Should Windows Be Cleaned in Cornwall?

Cornwall's unique coastal and maritime climate creates conditions that cause windows to become dirty faster than in most other parts of the UK. Understanding why — and how to set the right cleaning schedule — can save you money and keep your property looking its best year-round.

Why Windows Get Dirty Faster in Cornwall

The main culprit is salt air. When sea breezes carry microscopic salt particles inland, they deposit on every surface they touch — including your windows. Salt is hygroscopic, meaning it attracts moisture, which causes streaking, hazing and eventually pitting on glass if left uncleaned.

Cornwall also experiences high rainfall, which contrary to popular belief does not clean windows. Rain carries airborne dust, pollen and pollution which bond to the glass surface. As rainwater evaporates, these contaminants are left behind as visible deposits.

Add in the algae-friendly mild, damp climate and you have the perfect conditions for green biological growth on frames and sills — especially on north and east-facing elevations.

Recommended Cleaning Frequencies

**Coastal properties (within 1 mile of the sea):** Every 4 weeks. Properties in Newquay, Perranporth, Padstow, Falmouth and other coastal towns are directly exposed to salt-laden air and should be cleaned monthly to prevent salt etching.

**Inland rural properties:** Every 6–8 weeks. Reduced salt exposure but increased organic debris (pollen, spores, dust) from surrounding countryside means bi-monthly cleans are typically sufficient.

**Urban and town-centre properties:** Every 6 weeks. Reduced salt but higher traffic pollution means regular cleaning is still important for appearance and glass protection.

**Commercial properties:** Every 2–4 weeks. First impressions matter for businesses. Most shops, restaurants and offices in Newquay and Truro benefit from fortnightly or monthly commercial window cleaning.

Signs Your Windows Need Cleaning

- Visible salt haze or white streaking on the glass

Green algae growth on frames or sills

Water spots that don't disappear after rain

Difficulty seeing clearly through the glass in bright sunlight

Dark deposits in the corners of frame and glass junctions

The Cost of Neglect

Regularly cleaned windows last significantly longer than neglected ones. Salt deposits, if left, will eventually etch into the glass surface causing permanent damage that no cleaning can reverse. Algae growth in rubber seals degrades them faster, leading to draughts and water ingress.

The cost of regular window cleaning is a fraction of the cost of replacing damaged glass or seals.

Setting Up a Regular Schedule

The easiest approach is to set up a regular cleaning round with a trusted local window cleaner. At Rob's Window Cleaning, we text you the day before every visit, clean to the same high standard every time, and you can adjust or pause your schedule whenever needed — no contract.

For most Newquay homeowners, we recommend starting with a 4–6 weekly schedule and adjusting based on how quickly your windows visibly soil between cleans.
