Paving stones are a popular choice for patios, paths, and garden areas across New Zealand. They add style, create clean lines, and can last for decades when they’re looked after properly. But over time, exposure to sun, rain, wind, moss, and dirt can make them look worn, faded, or stained. The good news is that with the right maintenance, you can keep your pavers looking as good as the day they were laid.Keeping paving stones in top condition is not only about appearance. Regular maintenance helps protect the structure of the surface, prevents weeds and moss from taking over, and can save money on repairs in the long run.

Why Regular Maintenance Matters

In New Zealand’s climate, paving stones face constant challenges. In coastal areas like Dunedin, salt in the air can cause surface wear. In shaded or damp spots, moss and mould can take hold, making the surface slippery and unsightly. In summer, strong UV light can cause colours to fade, while in winter, frost can damage unsealed surfaces. Without regular cleaning and protection, these issues can build up, leading to a less attractive look.

Regular maintenance keeps your outdoor areas safe and looking well maintained. It also helps maintain the value of your property. A well-kept driveway or patio makes a better impression and shows that the space has been cared for. It’s also easier to maintain pavers a little at a time than to leave them for years and then try to fix a badly stained or damaged surface.

Steps for Looking After Your Paving Stones

  • Sweep regularly: Use a stiff outdoor broom to remove leaves, dirt, and debris before they cause stains.
  • Rinse with water: A gentle hose-down every couple of weeks helps prevent dirt from building up. Avoid using a high-pressure washer too often, as it can damage the surface. Do not use a water blaster on exposed pebble pavers.
  • Treat stains quickly: Oil, grease, or wine spills should be cleaned as soon as possible with a suitable cleaner for your paver type. Avoid concrete acid wash with coloured pavers.
  • Control weeds: Pull out weeds or treat them before they spread.
  • Seal coloured pavers: Applying a quality sealant every few years protects against stains, fading, and moisture damage.

Cleaning and Sealing for Long-Term Protection

The most effective way to keep paving stones looking new is to combine regular cleaning with periodic sealing. Start with an annual deep clean. Sweep the area, treat any moss or mould, and wash with a mild detergent and water. For stubborn dirt, a low-pressure setting on a water blaster can be used (but not for exposed pebble pavers), and keep the nozzle at least 30 cm away from the surface to avoid damage.

Once the pavers are completely dry, sealing them provides a protective layer that resists stains, blocks UV damage, and makes cleaning easier in the future. Sealers come in different finishes—matt, satin, or gloss – so you can choose the look you want. In New Zealand, sealing is especially useful for coastal or high-rainfall areas where pavers are more exposed to harsh elements.

Choose a sealer that’s suitable for your paver material. A good sealer should last three to five years, depending on foot traffic and exposure. You’ll know it’s time to reseal when water stops beading on the surface and starts soaking in more quickly.

Fixing Common Problems

Even with regular care, paving stones can develop issues over time. The good news is that most are easy to fix if you deal with them early.

If you notice weeds or grass growing between the pavers, remove them by hand or use a weed-killer that’s safe for hard surfaces. Fill holes left by weed removal to discourage regrowth. For moss and mould, a specialist outdoor cleaner can be applied and left to work before rinsing off. In heavily shaded areas, there will be more work to do.

Stains should be dealt with quickly to prevent them soaking in. Oil stains can often be lifted with a degreasing cleaner, while organic stains from leaves or berries may come off with sugar soap and water plus scrubbing. Avoid using harsh acids unless you know your pavers can handle them, as they can damage certain finishes, especially coloured pavers.

With these simple steps, you’ll get more years of use and enjoyment from your paving stones. They’ll continue to be a feature you can be proud of, adding beauty, safety, and value to your outdoor spaces for decades to come.
