Block paving should be cleaned at least once a year and sealed every three to five years to maintain its appearance and protect it from weeds, stains and weather damage.
Here at Swiss Seal, one of the questions we're asked most often is how frequently block paving should be cleaned and sealed. Our advice is simple. Regular cleaning and sealing at the right time will protect the surface, keep weeds under control and help your paving look its very best for years to come.
How often should you clean block paving?
Block paving should be cleaned at least once a year to remove dirt, moss, algae and surface stains.
Over time, the British weather leaves its mark on every driveway. Damp conditions encourage moss and algae, while everyday use brings tyre marks, oil stains and general grime. We recommend annual block paving cleaning and sealing as part of your maintenance routine. Keeping the surface clean not only improves its appearance but also prepares it properly for resealing when the time comes.
How often should block paving be sealed?
Block paving should normally be sealed every three to five years, depending on its condition and level of use.
A quality driveway block paving sealer creates a protective barrier that helps resist stains, water penetration and weather damage. Busy driveways or areas exposed to harsh conditions may need resealing a little sooner, while quieter areas often remain protected for longer. We always suggest checking whether water still beads on the surface, as this is usually a good indication that the sealer is still doing its job.
Does sealing help stop weeds growing?
Yes, sealing helps reduce weed growth by limiting the spaces where seeds and moisture can settle.
It's worth remembering that weeds usually grow in the joints rather than through the blocks themselves. While no sealer can prevent every weed from appearing, a quality driveway block paving sealer helps stabilise the jointing sand and reduces moisture, making it much harder for weeds and moss to establish. We've seen many customers spend far less time weeding after sealing their paving properly.
Can a block paving restorer improve old paving?
Yes, a block paving restorer can revive tired paving before it is sealed.
Years of sunlight and weather gradually dull the original colour of block paving. Applying a suitable block paving restorer before sealing can bring back much of that lost appearance, leaving the driveway looking fresher and more attractive. We often recommend this approach for older paving that's structurally sound but beginning to look a little faded.
What's the best way to maintain block paving?
The best way to maintain block paving is through regular cleaning, timely repairs and resealing when needed.
Here at Swiss Seal, we've seen just how much difference proper maintenance makes. A clean, well-sealed driveway doesn't just improve your home's appearance; it also lasts longer and stands up better to the British weather. By using a quality block paving restorer where needed and applying the right driveway block paving sealer at the right time, you can enjoy attractive block paving that continues to perform brilliantly for many years to come.
