Before and after photo of a recent paver project. We used hot-water pressure washers to steam-clean the pavers before applying the sealer. In addition to the upgraded appearance, the pavers are now easier to clean and protected from spills and stains like oil, grease, etc. The before photo is actually after we cleaned the pavers, just before sealer was applied.
