Block paving remains one of the most popular choices for driveways, patios, and pathways across the UK. With its timeless style, long-lasting durability and customisable design options, it’s no surprise that so many homeowners turn to this tried-and-tested surface.

But like any exterior feature, your block paving needs proper maintenance to keep it looking fresh, functional, and free from issues like weeds, staining, or surface movement. Whether your driveway is newly installed or has been in place for years, this guide from Crown Paving Ltd explains exactly how to maintain your block paving to the highest standards.

Why Maintenance Matters

While block paving is renowned for its strength and resilience, it still faces the full force of the British weather. Rain, frost, algae, moss, and general wear and tear can all take their toll over time. Routine maintenance not only protects your investment but also ensures your driveway remains an attractive feature that enhances the kerb appeal of your home.

Regular upkeep will also help avoid costly repairs in the future—so it’s worth taking a little time now to extend the lifespan of your paving.

Step-by-Step Guide to Maintaining Block Paving

1. Sweep Regularly

The simplest and most effective way to maintain your block paving is to sweep it regularly. Using a stiff-bristled broom, remove debris like leaves, dirt, and loose stones. This prevents organic matter from building up, which can lead to moss and weed growth if left unchecked.

Aim to sweep your driveway at least once a fortnight, or more often in autumn when falling leaves are a common issue.

2. Remove Weeds and Moss

Even though block paving is laid on a compacted sub-base, weeds can still grow in the joints between the blocks. It’s important to tackle these early before they become more established.

You can remove weeds manually or use a weed killer suitable for hard surfaces. Be cautious with chemical products if you have pets or children and always follow the manufacturer’s instructions. For moss and algae, a diluted bleach solution or specialist patio cleaner can help, followed by a thorough rinse with clean water.

3. Power Wash Occasionally

A periodic pressure wash helps restore the appearance of your block paving and removes ingrained dirt, grime, and surface discolouration. However, it’s essential to take care when using a power washer, as excessive pressure can dislodge the jointing sand and even damage the surface.

Use a fan nozzle at a shallow angle and sweep evenly across the surface. Avoid holding the nozzle too close, and never use a jet washer on full power. Once complete, allow the area to dry before brushing in fresh kiln-dried sand (see below).

4. Re-Sand the Joints

After power washing or once jointing sand has worn away over time, it’s important to replace the sand between the blocks. Jointing sand helps lock the paving in place and prevents movement, so neglecting this step can lead to instability and uneven surfaces.

Use kiln-dried sand, which is fine and dry enough to fall between the joints. Sweep it over the area and allow it to settle into the gaps. You may need to repeat the process after a day or two, as the sand continues to bed in.

5. Consider Sealing

Applying a block paving sealant can offer an extra layer of protection against staining, fading, and weed growth. Sealants form a barrier that repels oil, water, and dirt, while also enhancing the colour of the blocks.

This isn’t essential, but it’s particularly beneficial for high-traffic areas or properties where oil spills (such as from vehicles) are more likely. It’s best to apply sealant during dry weather when the surface is clean and fully dry. You can choose between matt, satin or gloss finishes depending on your preferred aesthetic.

Common Issues to Look Out For

While regular maintenance helps avoid most issues, it’s wise to keep an eye on the condition of your block paving and address any problems early:

  • Loose or sunken blocks – often due to ground movement or lack of proper sub-base. These can usually be lifted and re-laid.

  • Discolouration or oil stains – treat with a degreaser or paving cleaner as soon as possible.

  • Efflorescence – a white powdery residue that can appear on new paving. This is harmless and usually fades with time and weathering.

  • Ant nests – can destabilise the bedding layer. Use ant control products and re-sand joints if disturbed.

Long-Term Care Tips

  • Avoid using metal shovels or sharp tools to remove snow or ice from your driveway—opt for plastic shovels to avoid scratching the surface.

  • Place mats under tyres if you park heavy vehicles in one spot consistently, to prevent permanent markings.

  • Tackle oil or food spills immediately with absorbent materials or specialist cleaners to avoid staining.
