What affects the cost of commercial pressure washing?
- Surface area (m²) — the single biggest driver. Most quotes are calculated per m² with a minimum call-out.
- Surface type — tarmac, concrete, block paving, resin, and delicate natural stone each need different pressure and nozzle settings.
- Level of soiling — routine cleans are quicker than heavily soiled sites with oil, algae, gum, moss or graffiti.
- Specialist treatments — oil-stain removal, chewing gum removal, graffiti removal, and re-sanding after cleaning are priced separately.
- Access & timing — out-of-hours cleans (overnight, early morning, weekends) to avoid customer disruption often add a small premium.
- Water & power — sites without on-site water supply or power may need a tanker / generator, which is factored into the quote.

Frequently asked questions
How much does commercial pressure washing cost per m² in the UK?
The typical UK commercial rate is £2.50–£5.00 per m² for standard surfaces. Heavily soiled areas, stained concrete, or surfaces needing specialist treatment can run up to £8–£10 per m².
Do you have a minimum call-out charge?
Yes — our commercial minimum is £129. This covers site survey, equipment setup, insurance and a small job (typically up to 40–50m² of standard paving or concrete).
Can you work out of hours so we don’t disrupt customers?
Yes. Overnight, early-morning, and weekend slots are available across Sussex and South London. Contract customers get out-of-hours visits at no additional premium.
Do you offer scheduled maintenance contracts?
Yes — quarterly, bi-annual, and annual maintenance contracts are typically 20–30% cheaper per visit and keep forecourts, car parks and service yards consistently presentable.
Can you remove oil stains, chewing gum and graffiti?
Yes — each needs a different treatment approach. Oil uses absorbent pre-treatment then hot pressure wash; gum uses steam or specialist gum remover; graffiti uses graffiti-specific solvents rated for the substrate.
Will pressure washing damage my block paving or resin?
No — we calibrate pressure to the surface. Block paving may need re-sanding after a deep clean (we can include this in the quote). Resin-bound surfaces need low-pressure or soft-wash treatment to protect the resin matrix.
Do you handle waste water and drainage responsibly?
Yes. For sites with sensitive drainage we use bunding mats, vacuum recovery, or water-containment systems to meet local environmental requirements.
Are you insured?
Yes — £10 million public liability, employer’s liability, and professional indemnity. RAMS provided for every commercial site before work begins.
