The quick answer: Block paving cleaning in the UK costs £3.50-6 per square metre in 2026, including re-sanding with kiln-dried sand. A typical single driveway (25sqm) costs £90-150. A double driveway (40sqm) costs £140-240. Adding sealing costs an extra £3-8 per sqm, bringing a full clean-and-seal to £6.50-14 per sqm.
This guide covers exactly what professional block paving cleaning costs, what the process involves, and whether sealing is worth the extra investment. Block paving requires re-sanding after cleaning to stabilize joints and prevent weeds, which is included in the price. Our block paving sealing guide explains long-term protection options in detail.
Block Paving Cleaning Prices by Driveway Size
Most professional cleaners quote by the square metre. Larger driveways get a better rate because the setup and travel costs are spread across more area.
Small Block Paving Driveway (15-25 sqm)
Typical: Single-car space, terraced or end-of-terrace house
- Clean + re-sand: £70-130
- Clean + re-sand + seal: £130-250
Small block paving driveways are common in newer housing developments around Redhill, Merstham, and Salfords. Despite the smaller area, minimum call-out charges mean the per-sqm rate is higher than larger jobs. Even so, the total cost remains very affordable.
Medium Block Paving Driveway (25-45 sqm)
Typical: Two-car driveway, semi-detached house
- Clean + re-sand: £100-225
- Clean + re-sand + seal: £200-450
This is the most common size for block paving driveways in suburban Surrey. Properties in Reigate, Banstead, Horley, and Epsom typically fall into this range. At this size, you start to see competitive per-sqm rates.
Large Block Paving Driveway (45-70 sqm)
Typical: Three-car driveway, detached house
- Clean + re-sand: £180-350
- Clean + re-sand + seal: £350-650
Detached properties in Dorking, Oxted, Leatherhead, and Reigate Hill often have driveways this size. The larger area means the best per-sqm pricing and excellent value from professional cleaning.
Extra Large Block Paving (70+ sqm)
Typical: Large detached property, turning circle, multiple parking areas
- Clean + re-sand: £280-480
- Clean + re-sand + seal: £500-900+
Premium properties with extensive block paving, common in affluent Surrey areas, benefit from the best per-sqm rates. For very large areas, negotiate package pricing that includes paths, patios, and kerbing at a reduced rate.
What's Included in Block Paving Cleaning?
Block paving cleaning involves more steps than cleaning other driveway surfaces. The joints between blocks create additional work that is essential for a good result.
Standard Block Paving Clean Includes:
- Weed removal: Pulling or scraping weeds from joints before pressure washing. Deep-rooted weeds need clearing first for the cleaning to be effective.
- Joint sand removal: Old, contaminated sand is washed out of joints during the cleaning process. This is unavoidable and is why re-sanding is essential.
- Pre-treatment: Application of moss and algae killer to loosen biological growth before washing. Our moss removal guide explains why this step is essential.
- High-pressure washing: Professional-grade pressure washing using rotary surface cleaners for even, streak-free results across all blocks.
- Edge and detail work: Cleaning around borders, kerbs, drain covers, and expansion joints that rotary cleaners cannot reach.
- Re-sanding: Once the surface has dried, fresh kiln-dried sand is swept into every joint. This stabilises the blocks, prevents weed regrowth, and deters ants from nesting.
- Debris removal: All waste material, old sand, and moss cleaned up and removed from site.
Optional Extras:
- Sealing: £3-8/sqm additional. Applied after cleaning and re-sanding. Protects against staining, weed growth, colour fading, and oil penetration. Lasts 3-5 years.
- Oil stain treatment: £10-30 per stain. Old oil stains need specialist degreaser application before or during cleaning. Our guide on removing oil stains from driveways covers the treatment process.
- Efflorescence treatment: £30-60. White salt deposits on the surface, common on newer block paving, require acid-based treatment to remove.
- Ant treatment: £20-40. Ant nests in the sub-base can undermine blocks. Insecticide treatment prevents recurrence after cleaning.
- Individual block replacement: £5-15 per block. Cracked, chipped, or sunken blocks can be replaced during the cleaning visit.
- Re-levelling sunken areas: £15-30 per sqm. Where blocks have sunk due to sub-base settlement, they can be lifted, re-compacted, and relaid.
Block Paving Cleaning vs Cleaning and Sealing
The biggest decision when having block paving cleaned is whether to add sealing. Here's an honest comparison:
Cleaning Only
- Cost: £3.50-6/sqm
- Results last: 12-18 months before significant weed and moss return
- Maintenance: Regular sweeping, spot weed treatment
- Best for: Budget-conscious homeowners, driveways cleaned regularly, areas with minimal shade
Cleaning and Sealing
- Cost: £6.50-14/sqm
- Results last: 3-5 years with dramatically reduced weed growth
- Maintenance: Occasional sweeping only — weeds struggle to establish in sealed joints
- Best for: Long-term value, driveways with persistent weed problems, colour enhancement, oil stain prevention
What Sealing Actually Does
Block paving sealer is a liquid coating applied after cleaning. It penetrates the surface of the blocks and fills the pores, creating a barrier against moisture, UV light, and organic growth. The result is a surface that resists staining, maintains its colour, and stays cleaner for far longer.
Sealer also locks the kiln-dried sand into the joints, dramatically reducing weed germination. Most customers who add sealing report 80-90% less weed growth compared to unsealed paving.
There are two main types of block paving sealer:
- Matt/natural finish: £3-5/sqm. Preserves the natural look of the blocks while providing invisible protection. Recommended for traditional or rustic-style block paving.
- Wet look/gloss finish: £4-8/sqm. Enhances the colour of the blocks and gives a "wet" appearance. Popular for darker or multi-coloured block paving where colour vibrancy is desired.

Factors That Affect Block Paving Cleaning Cost
1. Condition of the Paving
Block paving that was cleaned within the last 18 months takes less time and costs less than paving that hasn't been touched in 5+ years. Heavy moss in joints, thick weed growth, and embedded dirt all add time to the job. Our block paving cleaning service handles even the most neglected driveways. Expect a 20-30% premium for heavily neglected paving.
2. Age of the Block Paving
Newer block paving (under 5 years) may have efflorescence (white salt deposits) that requires additional treatment. Very old block paving (20+ years) may have faded colour that responds beautifully to cleaning and sealing but might have blocks that need replacing.
3. Complexity of the Layout
Simple rectangular driveways are fastest to clean. Curved borders, intricate herringbone patterns, decorative bands, and multiple levels all add time because edges and transitions need hand-finishing. Complex layouts can add 10-20% to the price.
4. Access and Water Supply
Easy access keeps costs standard. If equipment needs to be transported through the house or up steep slopes, expect a £20-50 surcharge. Properties without an outside tap may need a water tank, adding further setup time.
5. Location
Surrey prices (£3.50-6/sqm) are at the upper end of the UK range. Within Surrey, prices are fairly consistent, with slightly lower rates in more competitive areas like Crawley versus premium postcodes like Reigate Hill or Cobham.
6. Combined Services
Having your block paving driveway cleaned alongside your patio, paths, or walls saves 10-20% compared to separate bookings. Most companies offer better per-sqm rates for combined jobs over 60sqm.
The Block Paving Cleaning Process
Understanding the professional cleaning process helps you know what to expect and evaluate whether a company is doing a thorough job.
Step 1: Assessment and Setup (15-30 minutes)
The cleaner assesses the paving condition, identifies any problem areas (oil stains, sunken blocks, heavy moss), and sets up equipment. Water supply is connected and the pressure washer is configured for the appropriate settings.
Step 2: Weed and Moss Removal (30-60 minutes)
Large weeds are pulled or scraped from joints. Heavy moss growth may be scraped off manually before washing. For badly neglected driveways, a biocide pre-treatment is applied and left to work for 15-30 minutes.
Step 3: Pressure Washing (1-3 hours depending on size)
Using a rotary surface cleaner at 2000-2500 PSI, the entire surface is systematically cleaned in overlapping passes. Edges, borders, and detail areas are finished with a hand lance at reduced pressure. Old joint sand is washed out during this process.
Step 4: Rinse and Inspect (15-30 minutes)
The entire area is rinsed down and inspected for any missed areas, stubborn stains, or damage. Any remaining problem areas are addressed.
Step 5: Drying (4-24 hours)
The paving needs to dry before re-sanding. In warm, breezy weather this takes 4-6 hours. In cool or humid conditions, it may take 24 hours. Some cleaners return the next day for re-sanding.
Step 6: Re-Sanding (30-60 minutes)
Kiln-dried sand is poured onto the dry surface and swept into every joint using a stiff broom. Excess sand is swept off. A vibrating plate compactor is used if available to settle the sand firmly into the joints.
Step 7: Sealing (if requested, 1-2 hours)
Sealer is applied in 2 coats using a roller or low-pressure sprayer. Each coat needs 2-4 hours to dry. The driveway should not be walked on or driven over for 24 hours after sealing.
Why Re-Sanding Is Essential
Re-sanding after cleaning is not optional — it's a critical maintenance step that many DIY cleaners skip, leading to rapid deterioration of the paving.
Kiln-dried sand in the joints serves three essential functions:
- Structural stability: The sand locks blocks together, distributing weight evenly. Without sand, blocks shift under vehicle weight, creating uneven surfaces and gaps.
- Weed prevention: Tightly packed sand leaves no space for weed seeds to germinate. Loose or missing sand allows weeds to establish within weeks.
- Insect deterrent: Ants are attracted to the warm, dry voids in empty block paving joints. Their tunnelling undermines the sub-base, causing blocks to sink. Properly sanded joints discourage nesting.
A 25kg bag of kiln-dried sand costs £4-6 from any DIY store and covers approximately 15-20sqm. For a full driveway re-sand, you'll need 2-4 bags depending on the area and joint width.
Regional Pricing: Surrey Block Paving

Block paving is particularly common across Surrey, especially in housing developments built since the 1990s. Areas like Crawley, Horley, and Redhill have large concentrations of block-paved driveways, supporting competitive pricing from local cleaners.
Frequently Asked Questions
How much does block paving cleaning cost?
Block paving cleaning costs £3.50-6 per sqm in 2026, including re-sanding. A typical 40sqm driveway costs £140-240 for cleaning, or £260-560 with sealing added.
Is re-sanding included in the price?
With reputable companies, yes. Re-sanding with kiln-dried sand should be included as standard. If a quote doesn't mention re-sanding, ask for it to be added — it's essential for the longevity of your block paving.
How often should block paving be cleaned?
Every 12-18 months for unsealed paving. Sealed block paving can go 2-3 years between professional cleans. Regular sweeping and spot weed treatment extends the time between visits.
Is sealing worth the extra cost?
For most driveways, yes. Sealing adds £3-8/sqm but prevents 80-90% of weed growth, protects colour, resists oil stains, and means the paving stays cleaner 2-3x longer. Over 3-5 years, sealing typically pays for itself in reduced maintenance.
