Why re-sanding matters
The sand between the blocks holds them in place. Cleaning removes the old, weedy sand, so the joints need refilling to keep the blocks tight and stop weeds getting straight back in.
Keep it clean for longer
Sealing block paving after re-sanding locks the sand in, stops weeds rooting in the joints and makes the yearly clean far quicker. It's the best value way to keep a driveway looking new.

AfterQuestions about block paving and driveway cleaning
Will the blocks change colour?
Cleaning brings back the original colour that has been hidden under dirt and growth. Sealing can deepen the colour slightly, depending on the sealer used.
Can you remove oil stains?
Fresh oil stains can often be lifted a long way. Old stains that have soaked in may fade rather than disappear completely, and I'll tell you which from the photos.
How long until I can drive on it?
You can drive on it the same day after a clean. After sealing, it needs time to cure, and I'll give you the exact time for your job.
