The quick answer: Professional pressure washing comes in three main service levels. A basic wash (£150-250) covers pressure washing, moss treatment, and re-sanding. A deep clean (£200-350) adds hot water treatment, oil stain removal, and extended techniques for heavily soiled surfaces. A full restoration with sealing (£300-500) includes everything plus surface sealing that protects for 3-5 years.

Basic Wash: What's Included
Cost: £150-250 for a standard 40m² driveway
Results last: 18-24 months
A basic professional wash is the most popular choice for UK homeowners. It delivers significantly better results than hiring a pressure washer yourself, with no time investment on your part.
Step-by-step process:
- 1. Surface assessment: The operator checks your surface type, identifies problem areas, and selects appropriate pressure settings
- 2. Pre-treatment: Moss and algae killer is applied and left to dwell for 15-30 minutes, loosening biological growth
- 3. High-pressure washing: Using 3000+ PSI professional equipment - roughly double the power of consumer machines
- 4. Rotary surface cleaning: Industrial spinning heads with multiple nozzles provide even, streak-free results across the entire surface
- 5. Edge and detail work: Careful cleaning around walls, obstacles, drain covers, and borders using hand-held lances
- 6. Re-sanding (block paving): Kiln-dried sand swept into joints to stabilise blocks and inhibit weed growth
- 7. Cleanup: Debris removed, drainage checked, site left tidy
Why this matters: Rotary surface cleaners eliminate the striping and uneven patches common with lance-only cleaning. Cold water at 3000+ PSI removes ingrained dirt that consumer machines leave behind. Proper re-sanding prevents the rapid weed regrowth that undermines cheaper cleaning.
Includes: All equipment, chemicals, sand, labour, public liability insurance (£2-5M), and a 7-day workmanship guarantee.
Best for: Regular maintenance cleaning, surfaces with moderate dirt and moss, tarmac and concrete driveways, homeowners who want reliable results without complexity.
Deep Clean: What's Included
Cost: £200-350 for a standard 40m² driveway
Results last: 24-36 months
A deep clean builds on the basic wash with more powerful equipment and additional treatments for heavily soiled surfaces. This is the right choice when a surface has been neglected for several years or has stubborn staining.
What's added beyond basic:
- Hot water system: Water heated to 80-90°C kills moss and algae at the root, not just the surface. Cold water removes visible growth but leaves roots intact to regrow within months
- Oil stain treatment: Specialist degreasers break down oil, grease, and tyre marks that cold water alone cannot shift
- Extended pre-treatment: Longer chemical dwell times and stronger concentrations for heavy biological growth
- Detail nozzle work: Multiple nozzle types (15°, 25°, 40°) used for different areas - tight joints, stubborn patches, and delicate edges
- Multiple passes: Heavily soiled areas may need two or three passes rather than the single pass of a basic wash
The hot water difference: This is the single biggest upgrade from basic to deep clean. Hot water kills biological growth completely, meaning moss and algae don't return for 2-3 years instead of 12-18 months. For north-facing or shaded driveways where moss is a persistent problem, hot water cleaning makes a dramatic difference.
Best for: Driveways not cleaned for 3+ years, heavy moss or algae growth, oil-stained surfaces, block paving with deep-set grime in joints, surfaces where a basic wash wouldn't be thorough enough.

Full Restoration with Sealing: What's Included
Cost: £300-500 for a standard 40m² driveway
Results last: 36-60 months (3-5 years)
A full restoration is the highest level of professional pressure washing service. It includes everything in a deep clean plus surface sealing that protects your driveway or patio for years. Despite the higher upfront cost, it often delivers the lowest cost per year of clean surface.
What's added beyond deep clean:
- Surface sealing: Quality sealant applied after cleaning (worth £3-8 per m² if purchased separately)
- Premium jointing sand: Sand with built-in weed inhibitor for block paving - far more effective than standard kiln-dried sand
- Post-sealing inspection: Touch-ups applied to any areas where sealant coverage is uneven
- 12-month satisfaction guarantee: Compared to 7-14 days for basic/deep clean
- Higher insurance: £5-10M public liability coverage
What Sealing Does for Your Surface
Sealing transforms the longevity and appearance of block paving, natural stone, and porous concrete:
- Extended cleanliness: Sealed surfaces resist dirt adhesion, staying clean 3-5 years vs 18-24 months unsealed
- Colour enhancement: Sealant brings out natural colours and provides a subtle sheen (wet-look or natural finish available)
- Stain resistance: Oil, grease, and organic stains sit on the surface rather than soaking in, making them easy to rinse away
- Weed prevention: Sealed joints dramatically reduce weed growth compared to sand-only joints
- Weather protection: Reduces water ingress, preventing frost damage and efflorescence (white salt staining)
- Easier maintenance: Simple hosing removes surface dirt without need for pressure washing
Our block paving sealing guide explains the sealing process and benefits in detail.
Best for: Premium surfaces (Indian sandstone, quality block paving), high-traffic driveways, oil-prone parking areas, properties being prepared for sale, homeowners who want maximum time between cleans.
Cost Per Year: Which Service Level Gives Best Value?
Upfront cost is misleading because results last different lengths of time. A better comparison is cost per year of clean driveway.
Example: 40m² block paving driveway in Redhill
| Service Level | Upfront Cost | Results Last | Cost Per Year |
|---|---|---|---|
| Basic Wash | £200 | 20 months | £120/year |
| Deep Clean | £280 | 30 months | £112/year |
| Full Restoration + Sealing | £400 | 48 months | £100/year |
Verdict: Full restoration with sealing offers the lowest annual cost despite the highest upfront price. Basic wash is the most affordable entry point and perfectly adequate for regular maintenance. Deep clean sits in the middle - ideal when your surface needs more than basic but sealing isn't necessary.
Which Service Level Suits Which Surface?
Surface type is the biggest factor in choosing the right service level.
Basic wash works well for:
- Tarmac driveways: Robust surface that responds well to standard pressure washing. Sealing provides minimal benefit on tarmac
- Modern concrete: Hard-wearing surface, straightforward to clean. Sealing optional but not essential
- Regular maintenance: Any surface cleaned within the last 18 months that just needs freshening up
Deep clean recommended for:
- Block paving with heavy moss: Hot water kills moss roots in joints, preventing rapid regrowth
- Neglected surfaces: Driveways or patios not cleaned for 3+ years need the extra treatment time
- Oil-stained areas: Car parking spaces, garage aprons, and areas with tyre marks need specialist degreasing
- North-facing surfaces: Persistent biological growth benefits from hot water treatment
Full restoration ideal for:
- Indian sandstone: Porous stone absorbs stains without sealing. Sealing is essential to protect the investment
- Premium block paving: Where appearance matters and you want maximum longevity between cleans
- Pre-sale preparation: Sealed driveways dramatically improve kerb appeal and perceived property value
- High-traffic areas: Multiple vehicles, frequent foot traffic - sealed surfaces cope better with heavy use

What Professional Equipment Costs (And Why It Matters)
Professional pressure washing equipment represents a significant investment that directly affects the quality of results you receive:
- Commercial pressure washer: £2,000-5,000 (vs £100-400 for consumer models)
- Hot water system: £3,000-8,000 additional
- Rotary surface cleaner: £500-1,500 (industrial grade with multiple nozzle heads)
- Chemical treatment systems: £500-2,000
- Vehicle and equipment total: £10,000-20,000+
This investment is why professional results are noticeably different from what you achieve with a hired machine. The equipment gap cannot be bridged by technique alone - higher PSI, hot water capability, and rotary surface cleaners fundamentally change what's possible.
