Pressure Washing Your Driveway: Before & After Guide

A clean driveway transforms the entire look of your property. Over time, algae, moss, oil stains, and general grime build up on driveways, making them look neglected and — in many cases — dangerously slippery. This guide covers everything you need to know about pressure washing driveway cost in the Norwich area, whether to DIY or hire a professional, and how to get results that last.

Why Does Your Driveway Need Pressure Washing?

Norfolk's damp climate is perfect for algae and moss growth. Even well-laid driveways develop a green film within a year or two, particularly in shaded areas or north-facing sections. This isn't just an aesthetic problem — a layer of wet algae on block paving or concrete is a genuine slip hazard, especially during autumn and winter when leaves and moisture compound the issue.

Beyond safety, there's a compelling financial argument. Estate agents consistently report that a clean driveway and tidy front garden add perceived value to a property. If you're preparing to sell a home in Thorpe St Andrew or Eaton, a freshly pressure-washed driveway is one of the cheapest ways to boost kerb appeal. Pair it with a garden clearance and regular garden maintenance to make the whole exterior shine for viewings.

How Often Should You Pressure Wash Your Driveway?

For most Norwich driveways, once a year is sufficient — ideally in spring, after the winter grime has accumulated and before the summer when you're using the garden most. Driveways in heavily shaded spots or under trees may benefit from a twice-yearly clean, particularly if leaf fall causes staining. Combining a spring pressure wash with an autumn leaf removal keeps your driveway looking its best year-round.

If your driveway has been neglected for several years, the first clean will be the most dramatic and may take longer. After that initial deep clean, annual maintenance washes are quicker and more straightforward.

Pressure Washing Driveway Cost in Norwich

Professional pressure washing driveway costs in the Norwich area vary depending on the size of the area, the surface type, and the level of soiling. Here's what you can typically expect to pay in 2026:

• Small driveway (up to 20m²): £80-£150
• Medium driveway (20-40m²): £150-£250
• Large driveway (40-80m²): £250-£400
• Re-sanding block paving (additional): £2-£4 per m²
• Sealant application (additional): £3-£6 per m²

These prices typically include weed removal from joints, cleaning, and a general tidy-up. Some companies charge by the hour (£30-£50/hour is typical for Norwich), while others charge a fixed price based on square footage. Fixed pricing tends to be better value and avoids surprises — something we believe in at GreenRun.

DIY vs Professional Pressure Washing

Hiring a pressure washer from a tool hire shop costs around £40-£70 per day. Add cleaning solution (£10-£20), and the total DIY cost for a medium driveway comes to roughly £50-£90 — significantly less than hiring a professional. So why wouldn't you do it yourself?

The Case for DIY

• Cheaper upfront cost
• You can do it on your own schedule
• Satisfying to see the instant results
• Suitable for small, straightforward driveways

The Case for Professional

• Commercial-grade equipment — professional machines deliver 3,000-4,000 PSI with rotary surface cleaners, compared to the 1,500-2,000 PSI of consumer models. The difference in results is dramatic.
• No risk of damage — incorrect technique can etch concrete, dislodge block paving jointing sand, or force water under pointing. Professionals know the right pressure and nozzle for each surface.
• Time saving — a professional can clean a medium driveway in 2-3 hours. DIY with a consumer machine takes a full day or more.
• Proper waste water management — run-off from driveway cleaning contains pollutants. Professionals manage this responsibly.
• Includes re-sanding and sealing — the real longevity of a clean comes from proper aftercare that most DIYers skip.

Pressure Washing Different Surfaces

Not all driveway surfaces respond the same way to pressure washing. Getting the technique wrong can cause costly damage.

Block Paving

The most common driveway surface in Norwich. Block paving cleans beautifully but is vulnerable to jointing sand loss. Use a rotary surface cleaner rather than a lance for even results. After cleaning, always re-sand the joints with kiln-dried sand — this prevents weed growth and stops the blocks shifting. Sealing block paving after cleaning locks in the sand and prevents algae returning for 3-5 years.

Concrete

Concrete driveways are robust and can handle higher pressures. However, older concrete may have a weakened surface layer that can be damaged. Start with lower pressure and work up. Concrete responds particularly well to a pre-treatment with a specialist cleaning solution left to dwell for 15-20 minutes before washing.

Tarmac (Asphalt)

Tarmac is softer than concrete and more prone to damage from high-pressure water. Use a maximum of 2,000 PSI and keep the nozzle further from the surface. Avoid using hot water on tarmac — it can soften the bitumen binder. Tarmac driveways in Norwich city centre and older areas of Sprowston are often 20+ years old and need a gentle touch.

Natural Stone

Indian sandstone, granite, and slate driveways look stunning when clean but are easily damaged by excessive pressure. Use low pressure (under 1,500 PSI) and a wide fan nozzle. Never use acid-based cleaners on natural stone — they cause irreversible etching and discolouration.

Sealing After Pressure Washing

Sealing your driveway after cleaning is the step most people skip — and it's the step that makes the biggest difference to how long the results last. A good-quality sealant creates an invisible barrier that prevents algae, moss, and weeds from taking hold, while also protecting against oil stains and UV fading.

For block paving, use a water-based sealant that allows moisture to escape from the substrate. For concrete, an acrylic or polyurethane sealer works well. The driveway must be completely dry before sealing — allow 24-48 hours after washing, weather dependent.

A sealed driveway can stay clean for 3-5 years compared to 12-18 months for an unsealed surface. Given that sealing costs around £3-£6 per m², it's a worthwhile investment that reduces your long-term cleaning costs significantly.
