Yes, when it is done with the right equipment and a little respect for how pavers are built. A paver surface is not a slab. It is hundreds of individual stones held in pattern by sand in the joints, and that sand is exactly what careless washing destroys. Blast the joints out and the pavers start shifting, edges chip, and weeds move into the gaps you just cleaned out for them.
What equipment and pressure do pavers need?
The tool matters as much as the operator. A rotary surface cleaner spreads the force evenly and keeps the spray at a consistent height, which is how large paver areas should be cleaned. Pavers are also typically washed gentler than plain concrete: where a concrete slab commonly takes 2,500–3,500 PSI, pavers are usually cleaned around 1,500–2,500 PSI, with softer or older stone at the low end of that range.
A bare wand in inexperienced hands is the classic failure. It cuts stripes into the surface, digs out joint sand in lines, and leaves a driveway that looks worse in raking light than before it was cleaned. Distance and tip selection do the rest of the work of keeping the stone safe; a wide tip held 12 or more inches off the surface behaves completely differently from a narrow tip at 3 inches, even on the same machine.
What should be checked before the wash starts?
Condition. Loose or sunken pavers, crumbling edges, and empty joints tell us the surface needs gentler handling and probably some restoration alongside the cleaning. White, chalky efflorescence needs the right treatment rather than more pressure, because force does nothing to a mineral bloom.
And if the surface was ever sealed, the wash has to respect the coating. Paver sealers in South Florida sun typically last 3–5 years, and stripping one accidentally with an aggressive wash shortens the life of something you paid good money for. How long those coatings last, and how to tell when one is due anyway, is covered in how long does paver sealing last.
What happens after a proper paver wash?
The joints usually want fresh sand. Washing inevitably lifts some joint material even when it is done carefully, and re-sanding locks the pattern back tight and slows the weeds and ants that love open joints. Skipping this step is how a clean paver surface starts moving within a year.
If sealing is on your list, cleaning and sealing belong in 1 coordinated scope, because the surface has to be washed and then fully dry, typically 24–48 hours, before sealer goes down. Doing them as one pressure washing and paver sealing project gets that timing right and saves paying for a 2nd mobilization. For how often the cleaning itself should recur, how often should a driveway be pressure washed covers the schedule side.
