The Risk of Too Much Pressure on Pavers
Concrete and natural stone pavers are more delicate than a solid concrete slab, and pressure washer settings appropriate for a driveway (2,500–3,000+ PSI) can blast out joint sand when applied directly to paver joints — leading to shifting, weed growth, and the need for costly re-sanding. Excessive pressure at close range can also etch or pit the paver surface itself.
Many DIY pressure washing mistakes on pavers happen from holding the nozzle too close or using too narrow a spray tip, both of which concentrate pressure well beyond safe limits.
The Correct Professional Approach
Professional paver cleaning typically uses 1,200–2,000 PSI with a wider fan tip held at an appropriate distance, combined with surface cleaner attachments that distribute pressure evenly and protect joint sand.
Following cleaning, Blues Home Services can restore any displaced joint sand with polymeric sand and recommend sealing to protect the surface. Call (214) 307-2127 for a free DFW paver cleaning estimate.
