It's a beautiful sunny Saturday morning. You've got your coffee, you're standing on your back patio, and you look down - yuck! When did your pavers get so dirty? Those pavers used to look so nice and new when you first had them installed. Now they're covered in grime, moss, mildew, and who knows what else.
You think to yourself, "I should power wash these to make them look new again!" So you haul out your heavy-duty power washer, attach the high-pressure nozzle, power it up, and let loose on those unsuspecting pavers. The dirt goes flying, and you smile, thinking, "Wow, it's working great! These pavers are going to look brand new!"
But are they? Can pressure washing damage pavers? Pressure washing can damage pavers if the pressure is too high, the nozzle is held too close, or poor technique is used. Proper pressure washing with moderate pressure, farther nozzle distance, and gentle motions can clean pavers safely.
Let's take a closer look and dive into the details.
Pressure washers work by shooting out an intense, concentrated stream of hot water at high pressure. Residential power washers generate anywhere from 1,500 to 4,000 PSI (pounds per square inch) of pressure. That's some serious power being blasted directly onto your pavers in order to scour off the top layer of dirt.
When used properly, this intense cleaning method can safely remove grime and debris without damaging the surface below. But crank up that pressure too high, get the nozzle too close to the pavers, or use the wrong washing technique and you could etch or score the pavers.
So what exactly is at risk when you power wash pavers? Here are some potential ways they could become damaged:
The key is moderation. You can absolutely pressure wash your pavers safely; just follow these tips:
Regular sweeping and gentle pressure washing when needed will keep your pavers looking fantastic for years. Just be cautious not to overdo the pressure, hold the nozzle too close, or aim directly at crevices between pavers. With some common sense care, you can keep your outdoor living space sparkling clean and prevent any damage to the pavers. So grab that power washer gently, and let's get these pavers cleaned up!

What will ruin pavers?
Using excessive pressure or harsh chemicals when cleaning pavers can damage the surface, causing etching, scoring, and erosion. Not properly sealing and maintaining pavers allows water penetration that leads to cracks, chips, freeze-thaw damage, and weed growth between pavers over time.
What PSI should I wash pavers?
To avoid damaging pavers when pressure washing, use a PSI of 1500-2000 and keep the nozzle at least 4-6 inches from the surface.
What is the best way to clean pavers?
The best way to clean pavers is with a pressure washer at 1500-2000 PSI using a fan nozzle held 4-6 inches above the surface. Sweep loose debris before washing to avoid forcing particles into paver joints. Move the nozzle slowly in wide strokes and avoid aiming directly at crevices. Let the pavers fully dry after washing before applying a new protective sealer. For routine maintenance, sweep frequently and use mild soap and water with a stiff brush to spot clean. Hire a professional power washing service annually for a deeper clean to keep pavers looking their best.
Should you seal pavers after power washing?
Sealing pavers after power washing is highly recommended to protect and enhance their appearance. The intense water pressure can erode the previous sealer coating and leave the pavers vulnerable to elements. New sealer will restore the rich color of the pavers and provide a protective barrier against UV rays, oils, and staining. Be sure pavers are completely dry before applying a fresh sealer coat per manufacturer instructions to maximize durability.
