One bummer about our paver driveway is that the pavers show tire tread marks and the pavers soak up any kind of oily material which forms a stain. Here you can see the driveway with the tread marks.
So we decided to have the driveway cleaned and sealed. I tried cleaning the driveway myself at first, with a standard power washer, but this was a disaster. The driveway wasn’t that clean in the end, and the power washer blew the stones out of the cracks between the pavers, which took many hours of sweeping over the next week to (mostly) get back in place. We have permeable pavers, which have spaces between the bricks filled with pea gravel, to allow the water to percolate down.
We managed to find a local stone and tile restoration company that would quote us on cleaning and sealing the driveway.
The first step was cleaning. They had a special power washing tool.
