Why Regular Maintenance Matters

A block paving driveway is a significant investment that adds real kerb appeal to your home. But it is not a case of laying it and forgetting it. Without a little care, joints can wash out, weeds can take hold, and the surface can start to shift. The good news is that maintenance is straightforward: regular sweeping, occasional pressure washing, and re-sanding the joints. Do these three things and your driveway will stay stable, safe, and looking smart through every season.

Sweep Little and Often

Sweeping is the simplest job you can do, and it pays dividends. A stiff-bristled broom is your best friend. Aim to sweep your driveway once a week, or more often in autumn when leaves fall. Sweeping removes grit, leaves, and dirt before they work their way into the joints. It also stops moss and weeds from getting a foothold.

• Use a stiff broom – not a soft household brush. Push the debris away from the house and garage, then collect it.
• Pay attention to edges and corners – these are where weeds and moss first appear. A hand brush helps here.
• Bin the sweepings – don't wash them into drains, as this can cause blockages.

If you spot a weed, pull it out straight away. A small weed today is a big root system tomorrow. For moss, a stiff brush will usually dislodge it, especially after a dry spell.

Pressure Washing Without the Pitfalls

Once or twice a year, a pressure wash will lift ingrained dirt and restore the colour of your blocks. But be careful: too much pressure can blast away the jointing sand and even damage the surface of the blocks themselves.

Use a fan nozzle rather than a pencil jet, and keep the wand moving. Work at a 30-degree angle to the surface, and never hold the jet in one spot. Start with the lowest pressure setting that does the job. For most driveways, a medium setting is plenty. If you have old or delicate blocks, consider a gentle wash with a garden hose and brush instead.

After washing, let the driveway dry completely. You will almost certainly need to re-sand the joints – see below. Never pressure wash on a frosty day, as water can freeze in the joints and cause cracks.

Re-Sanding: The Secret to a Stable Driveway

Jointing sand is what locks your blocks together and stops them from moving. Over time, rain, wind, and traffic wash or blow it away. When joints are empty, blocks can wobble, weeds can grow, and water can pool. Re-sanding is the single most important maintenance job you can do.

Use kiln-dried sand or a proprietary jointing sand – not ordinary builder's sand, which can contain clay and never sets properly. The best time to re-sand is after pressure washing, on a dry day. Pour the sand over the driveway and work it into the joints with a stiff broom. Fill them completely, then sweep off the excess. For a thorough job, compact the sand with a vibrating plate compactor – but if you don't have one, a few passes with a heavy roller or even your car tyres will help settle it.

• Top up twice a year – spring and autumn are ideal. If you can see the joints are low, add more sand.
• Keep sand off the surface – any excess left on top can stain or be tracked into the house. Sweep it away.
• Water lightly – a fine mist helps the sand settle, but don't soak it. Let it dry naturally.

Seasonal Jobs to Keep Your Driveway Tip-Top

Your driveway faces different challenges throughout the year. Here's a simple seasonal checklist.

• Spring: After winter, check for cracked or lifted blocks. Re-sand joints and pull any weeds that have appeared. A light pressure wash removes winter grime.
• Summer: This is the best time for a deep clean and re-sand. Keep an eye out for ant nests – a little ant powder or boiling water can sort them before they undermine the joints.
• Autumn: Sweep leaves regularly – wet leaves are slippery and can stain. Clear gutters and drains so water doesn't pool on the driveway. Re-sand if needed before winter.
• Winter: Avoid rock salt, which can damage block paving over time. Use a shovel rather than a metal ice scraper. If you must de-ice, use a small amount of white vinegar mixed with water, or a dedicated paving-friendly de-icer. Never use a pressure washer on frozen ground.

With a little routine care, your block paving driveway will reward you with decades of good looks and reliable performance. It's not hard work – just a few hours a year – and it saves you from costly repairs down the line.
